Bone erosion are clearly evident on computed tomography, but not on the corresponding radio graph. The wrist is one of the most diffcult joint of the body to assess radiographically [61]. Early rheumatoid arthritis involving the of conventional radiography for a detailed eval wrist.

Additional limitations of conventional radiogra the hypothesis that chronic infammation and phy are the following: (a) technical variables, (b) joint destruction are closely linked is further interpretational variables, and (c) pathophysio supported by data from imaging studies. Reasons are that closely related to a poor long-term clinical out radiographs of hands and feet can be easily come [78-80]. Infammation of the joints may showed that within 3 months of disease onset, fuctuate over time in individual patients, and 34.

Each erosion scores one assessing medication effcacy and in following point, with a maximum of fve points for each response to treatment. One assessment for the whole patient [91, 92], point is scored for focal joint narrowing, two whereas others score specifc joint abnormali points for diffuse narrowing of less than 50% of ties [93, 94] (Table 2). Radiographic scores, the original space, and three points if the reduc such as the Sharp scores and their modifca tion is more than half of the original joint space. The score for erosion for method had several limitations and is no longer both hands ranges from 0 to 98. The total erosion score and the total joint of the hands, wrists, forefoot, and cervical score are each normalised based on a maxi spine [94]. One point is scored sions (usually no joint space left and the origi if erosions are discrete, rising to 2, 3, 4, or 5 nal bony outlines are only partly preserved); depending on the amount of surface area and 5 = mutilating changes (the original bony affected (complete collapse of the bone is outlines have been destroyed) (Table 3). The Larsen original method scoring of an individual joint to defnite changes has also been modifed several times by the of erosion and joint destruction. In the 1977 version [102, 103], the six of the erosion into the bone is not considered. Grades are then assigned in abnormalities; grade 3 = medium destructive this way: grade 1 = one or several defnite ero abnormalities; grade 4 = severe defnite abnor sions totalling destruction of <20% of the total malities; and grade 5 = mutilating abnormali surface; grade 2 = joint surface destruction ties.

Step 1 assesses whether you understand and can apply important concepts of the sciences basic to the practice of medicine, with special emphasis on principles and mechanisms underlying health, disease, and modes of therapy. Step 2 ensures that due attention is devoted to principles of clinical sciences and basic patient-centered skills that provide the foundation for the safe and competent practice of medicine. The clinical skills examination began in June 2004 and is a separately administered component of Step 2. Step 3 assesses whether you can apply medical knowledge and understanding of biomedical and clinical science essential for the unsupervised practice of medicine, with emphasis on patient management in ambulatory settings. Step 3 provides a final assessment of physicians assuming independent responsibility for delivering general medical care. Students who fail their second attempt will continue to be assigned to Independent Study. Failure to pass, after the third attempt will result in automatic dismissal from the School of Medicine. At the discretion of the Associate Dean for Student Affairs and the Senior Associate Dean for Education and Academic Affairs, such students will be allowed to walk with their class at commencement and will receive a diploma with a later date, if it is anticipated that they will have met all graduation requirements within a reasonable time after commencement. Passing scores must be documented no later than April 15th of the year the student expects to graduate. Failure to document a passing score for either Step 2 exam by April 15th will result in a delay in graduation. Step 1 has therefore become the one objective measure common to all residency program applicants that program directors feel they can rely on to help them compare and assess applicants. A very good performance on Step 1 can definitely help when it comes to securing a top-rate residency, and a poor score can hurt by limiting your options. Bottom line although Step 1 is only one of many criteria that will be used in evaluating your residency application, it is definitely in your best interest to do all you can to maximize your chances of doing well, regardless of what type of specialty training you may choose to pursue. The number of test items you answer correctly is converted to a three-digit score scale. Blocks of items on Step 1 are constructed to meet specific content specifications. The earlier your application is submitted, the sooner you can schedule your test date. People who wait until mid-spring will have difficulty getting their first choice of test dates. If your application is submitted more than six months in advance of your requested eligibility period, it will be processed, but your Scheduling Permit will be issued no more than six months before your assigned eligibility period begins. You should verify the information on your Scheduling Permit before scheduling your appointment. You will not be able to take the test if you do not bring your Scheduling Permit to the test center. Note: Your Scheduling Number is needed when you contact Prometric to schedule test dates. Please keep the following in mind: You must have your Scheduling Permit before you contact Prometric to schedule a testing appointment. If you must reschedule outside the approved eligibility period, you will need to reapply and pay an additional fee.
The three main causes blood pressure chart with age and gender buy 12.5mg microzide free shipping, from most to least prevalent hypertension zoloft order microzide 25 mg line, are joint instability ulterior motive synonym buy microzide us, direct trauma blood pressure bottom number buy generic microzide line, and degenerative arthritis blood pressure chart infants order discount microzide on-line. Far and away blood pressure prescriptions cheap microzide 12.5mg overnight delivery, the most common reason for nerve entrapment in the spine blood pressure is purchase discount microzide online, whether the neck or the back heart attack clothing purchase microzide amex, affecting the spinal nerve roots or autonomic nervous system is joint instability. It is common when patients come to our office to already have seen 5 or more doctors and been given diagnoses such as spinal stenosis, cervical radiculopathy, lumbar degenerative disc disease, and been told that they need various surgeries such as decompressive laminectomy with or without spinal fusion to decompress the compressed nerve and/or spinal cord. Again we cannot emphasize this enough, if the symptom is not present in a significant manner 24/7 and specific activities reduce the symptoms such as sitting or lying down, then dynamic joint instability is the correct diagnosis and Prolotherapy is the correct treatment. If the degenerative process is well-advanced, and it is causing a significant narrowing of the nerve canal and it is strangling the nerve 24/7, then clearly no motion or position will relieve symptoms. This type of static compression does affect nerve transmission and significant symptoms are normally present. If the nerve transmission is not going to your skin, you get a true numbness, and the same goes for muscles, as weakness and atrophy are seen. When given a diagnosis of any of the nerve pain conditions which commonly end with the words neuritis, neuralgia, neuroma, or syndrome, a person should run, not walk, to the nearest Prolotherapist and run, not walk, away from any neurologist or orthopedic surgeon! Most of these conditions are easily treated with one of the four natural injection therapy techniques described in this chapter. If the syndrome involves an irritated, compressed, or sensitive (to stretch or touch) nerve, most likely a simple in-office natural injection technique is needed to restore the nerve to health along with all of the tissues it innervates! Nerves connect your brain and spinal cord to everything in the body, including muscles, ligaments, skin, and organs, providing movement and feeling. Nerves are primarily responsible for the transmission of communication between cells and even between organs or joints and the brain. Rest assured, however, the local environment of the cell takes a priority compared to the organism as a whole. They know something is wrong locally and will notify the brain by sending out pain signals. These sensitized nerves in the area of an injury, including joint instability, are said to have neurogenic inflammation, whereby the compressed nerves themselves release inflammatory substances such as substance P, histamine, interleukins, and cytokines that can cause significant local pain. Nerve homeostasis fortunately can be restored with natural injection therapy such as Lyftogt Perineural Injection Therapy. This can produce far-reaching effects to organs and even physiological changes in the central nervous system (brain and spinal cord) including the autonomic nervous system, which controls everything that happens in the body automatically such as breathing, heart rate, and blood flow. As you can see, these types of injuries need to be taken very seriously and treated as soon as possible. The cervical spine can be thought of as the main passage way through which the central nervous system connects to the peripheral nervous system. Cervical instability may affect both the peripheral and central nervous systems, resulting in many unusual and often bizarre symptoms and syndromes. Unfortunately, many of these patients have spent a lot of money to see a myriad of practitioners with little to no resolution of the problem. Not until the underlying cause of the problem is addressed can patients with these symptoms find complete healing. We have been blessed to help many people find hope again and go on to live normal lives. The sympathetic nervous system revs up the body to handle stress and the parasympathetic repairs the damage from the stress, producing relaxation of the body. Capsular ligament laxity (weakness) causes anterior cervical instability with neck flexion, producing impingement of the cervical sympathetic ganglion. Cervicocranial syndrome accounts for many of the seemingly odd array of symptoms post neck trauma. Joint instability etiology of various nerve entrapments and unusual pain syndromes. A stable cervical spine plays a vital role in allowing us to live vibrant productive lives! Nerves alert the brain to the presence of an injury or problem because the nerves are inflamed, entrapped, or encountering excessive stretch. The hallmark sign of nerve irritation is neurogenic pain which produces significant symptoms including sharp pains when an extremity is moved or touched in a normal non-painful way. The most common cause of all nerve pains is ligament injury leading to joint instability. When a ligament is injured, the nerves within it experience excessive stretch and start firing. When a symptom is improved or worsened by motion or activity, the symptom is said to be dynamic. Many nerve entrapment conditions and syndromes including carpal tunnel syndrome, occipital neuralgia, thoracic outlet syndrome, piriformis syndrome, cervical and lumbar radiculopathy, and even spinal stenosis occur as a result of joint instabilities. Because the extra space for nerves, including vertebral foramina or tunnels, is only 1 to 2 mm, microinstability of joints, can cause bones to move enough to compress nerves. When this happens, positions or movements where the tunnel or foramina is open may occur, thus temporarily eliminating the nerve compression, so symptoms abate. Other positions or movements may cause the nerve space to narrow and symptoms increase. This dynamic (changing) component of the symptomatology is a sign that joint instability is the cause and Prolotherapy is the cure. Neuropathic pain from neurogenic inflammation caused by nerve entrapment or excessive nerve stretch occurs because of joint instability and requires Prolotherapy to resolve the symptoms long-term. One of the common causes of neurogenic inflammation is chronic constriction injury in the fascia where nerves become entrapped. Both of these treatments involve the injection of natural solutions, including 5% dextrose, to release nerve entrapments and restore health and homeostasis to the inflamed nerves. As the entrapped nerve is released immediately, symptoms may often improve or resolve instantaneously. Sometimes several sessions may be required to produce long-lasting resolution of the nerve pain and symptoms. When these symptoms are associated with neck popping, cracking, or grinding with or without a history of chiropractic or self-manipulation, cervical instability can be assumed and the best treatment is Prolotherapy. Each day connective tissue itself, along with the cells that make it, need to be replenished. When catabolic (breakdown) processes exceed anabolic (build-up) ones, a connective tissue deficiency or weakness occurs. Diagnoses such as fibromyalgia syndrome, myofascial pain syndrome and symptoms such as whole body pain or achiness and plain-oljust feeling awful occur. While symptoms can range from mild in those who are sedentary to moderate for more active individuals, symptoms are generally severe after strenuous activity. As in all conditions, the goal is to get at the root cause of the problem and then resolve it! Prolotherapy is an excellent option to strengthen the weakened ligaments in the spine and other painful joints that are causing pain throughout the body! It provides hope and pain relief in some of the most painful, and often hopeless, conditions. The body has tremendous regenerative capabilities, but one must never forget the fact that many different factors affect connective tissue healing. While hypermobility is a feature common to them all, they are all believed to be caused by a defect in collagen, the essential connective tissue protein responsible for tensility and integrity of skin and joints tissues. Reversing connective tissue deficiency syndrome involves many different factors including diet, medications, and other metabolic factors. Hypermobile joints are exhibited by bending the elbow or knee past the neutral position, touching the floor with the palm while bending at the waist, and touching the thumb to the forearm. As we have been discussing, when ligaments are weak, joints become loose and unstable. Affected individuals over 40 years of age typically have recurrent joint problems and almost universally suffer from chronic pain. Other common clues in children, adolescents, and adults that suggest joint hypermobility is present includes recurrent joint dislocations, frequent ankle sprains, child with poor ball catching and handwriting skills, premature osteoarthritis, as well as laxity in other supporting tissues and structures. One reason for this is doctors and other health4 care providers are trained to examine for reduction of joint mobility rather than for an increased range, so that hypermobility is commonly missed. Joint hypermobility is diagnostically evaluated according to the Brighton criteria, which utilizes the Beighton score. The Beighton score measures the ability to perform certain hyperextensive functions, including significant flexion of the thumb and fifth finger, hyperextension of both knees and elbows greater than 10 degrees, and the ability to place the palms on the floor with the knees fully extended, by assigning a point to each of these functions. Generally the diagnosis is made by a family history of the condition and the clinical evaluation. Genetic testing and muscle and skin biopsies confirm the connective tissue (collagen) disorder. A score of 4 or greater is problems seen in the various types indicative of generalized joint hypermobility. Wound healing is delayed, and the stretching of scars after apparently successful primary wound healing is characteristic. Over the next 12 years, the pain and joint subluxations spread to other joints including the other knee, elbows, shoulders, and spine. Ellie tried many different forms of therapy including physical therapy, massage, ultrasound, taping, and compression braces which managed her pain well enough to perform daily activities as well as gymnastics, track, and cross country. At the age of 19, she tore the meniscus in her right knee and underwent surgical meniscus repair. Following the operation, she experienced intense pain, and subsequently underwent a second operation. While the symptoms in her knee appeared to be resolved, pain in her other joints persisted. During this time, Ellie also began experiencing other health issues including hypothyroidism, eczema, chest pains, food allergies, irregular menstrual periods, and degenerative disc pain in her neck and back. In the search for a treatment for her joint pain, Ellie found Prolotherapy, which she felt was needed for the pain in her neck, thoracic, low back, knees, and shoulders. During this time, she continued physical therapy, and managed her pain with multiple medications. After a year and a half of minimal improvement, her pain doctor referred her to Caring Medical for Prolotherapy. As a 21 year old college student, Ellie was living with constant joint pain, which disturbed her ability to exercise, study, and sleep. By this time, she also suffered from joint dislocations in her shoulders and elbows causing its own amount of excessive pain and stiffness. Within a week of her first visit, Ellie reported a decrease in her thoracic and scapular pain and improved physical stamina and energy. A month later, she began running again and no longer required treatment to her knee. By her second visit, Ellie had discontinued all use of pain patches, and only required occasional Tylenol for pain and muscle relaxers to help her sleep. For the next six months, Ellie continued to receive monthly treatments to her neck, thoracic, and shoulders, showing gradual improvement of pain and well-being. After eight months of treatments, Ellie no longer required any pain medications, was no longer experiencing any joint dislocations, and was back to running and gymnastics. She was seen an average of once per year throughout her college and Masters program. These patients present with a wide variety of readily identifiable traumatic and overuse lesions, such as traction injuries at tendon or ligament insertions, chondromalacia patella, rotator cuff lesions, or back pain due to soft tissue injury or disc herniation. Others suffer the effects of joint instability, such as flat feet, recurrent dislocation or subluxation-notably of the shoulder, patella, metacarpophalangeal joints, or temporomandibular joints. Many hypermobile patients also experience myofascial pain, which may be explained by the extra stress placed on muscles to compensate for lax joints as the muscles attempt to stabilize the joints. One of the more serious long-lasting affects of joint laxity is chronic joint degeneration. The increased mechanical stress caused by ligament laxity leads to chronic joint instability, making them more susceptible to soft tissue injuries. Continual instability and injury leads to an earlier onset of degenerative joint disease in hypermobile and other patients with ligament injuries 20,26-28 than in the normal population. Types of Hypermobility Example: Example: Example: A shoulder, knee, or Joint hypermobility syndrome Ehlers-Danlos syndrome, Hypermobility elbow is lax or prone Type Marfan syndrome to dislocation. Hypermobility of four or Osteogenesis Imperfecta more joints occurs in the Ligament laxity absence of any rheumatologic Hypermobility is congenital and occurs in a single disease, characterized by joint caused by an inheritable defect. Efects joint or multiple joints hyperextension, arthralgia, and are multisystemic and can include independent of each joint dislocation or vertebral cardiac, optical, uterine, gastrointestinal, other.

This has become an epidemic in the offices of any practitioner treating chronic pain Figure 17-8: Over-manipulation syndrome symptoms. A high velocity manipulation consists of a violent thrust and contortion of the spine to achieve the audible popping sounds or cracking of the cervical, lumbar, or even thoracic spine in an attempt to realign or adjust the spine. However, patients who sign up for long-term chiropractic packages that include thrusting manipulations often find themselves even more unstable after the treatment course. Ligaments in the neck, for instance, can be injured by as little as 10 newtons of force and high velocity thrusting can cause forces greater than 1000 newtons. The force required to move a subluxed vertebrae or bone into place, should be minimal. Muscle spasms are often a complaint of people who suffer from loose joints, and those who have been diagnosed with over-manipulation syndrome. The capsular ligaments, which hold the cervical, thoracic and lumbar vertebrae in place are typically injured with a rotational force. When a person self-manipulates or receives a high velocity thrust by a health care practitioner before the muscle stiffness or spasm has been addressed a supraphysiological rotation force is applied. Then the muscles have to overcompensate in order to stabilize the joint, leading to tight muscles and muscle spasms. So it is easy to see how this can become a vicious cycle of pain, ligament laxity, muscle spasms, more pain, etc. It has been evident for many years that patients who continue to self-manipulate or receive high velocity manipulations either need many more sessions than other people receiving Prolotherapy for the same condition that did not manipulate, or they simply do not get better. When receiving Prolotherapy, you should not manipulate the body part receiving Prolotherapy or have anyone else do it either! Some of our neck patients claim to have never had neck issues until after seeing a chiropractor for an unrelated condition. This then began a pattern of receiving continued adjustments for chronically subluxing and suffering for years until they found out about Prolotherapy. By the time they reach our office, they had all the same symptoms as whiplash-associated disorder (from cervical instability): neck pain, stiffness, vertigo, dizziness, ringing in the ears, swallowing difficulty, stress, anxiety, racing heart, severe fatigue and memory issues. For those getting 20+ adjustments, our experience has been that at least one of those will be too forceful or aggravate cervical instability. The anatomical dangers can clearly be understood if we consider the movement of a joint. Our muscles move a joint from neutral to a certain point, which is called active movement. Passive movement includes the same range of motion as active movement plus a little more. Think of this as turning your head to the right, but then taking your hand to push your head a little further to look over your right shoulder. Beyond active movement and passive movement is the anatomical limit, which is where the joint should stop due to the ligament becoming taught. Active movements are those movements performed using muscular power, such as turning the head. Passive movement occurs when someone else gently pushes the head further to one direction. When a supraphysiological force (force greater than a passive movement) is applied, additional motion can occur, as in a high velocity thrust. Repeated adjustments for a hypermobile patient is not helpful because it will worsen the hypermobility and instability. If after numerous adjustments, the joint is still not staying in place after manipulation, then there is an obvious ligament injury. Treatment to stabilize the vertebrae by strengthening the Figure 17-11: Self-manipulation causing ligaments is necessary.

Urologist: A doctor (physician) who diagnoses and treats disorders of the urinary system. Vein: Blood vessel carrying blood to the heart form the various parts of the body. Venous line: In hemodialysis, the tubing that returns the clean blood from the dialyzer back to the patient through the access. Literal Definition: K = fractional clearance of the dialyzer (efficiency in removing urea from the body water) t = actual time in a dialysis session V = volume of body water from which urea is removed. Functional Definition: Kt/V is a precise way of expressing the dose of dialysis given. It is necessary to understand that the larger the "V," the greater the clearance and/or the longer the time necessary. The prescribed Kt/V may not equal the delivered Kt/V because neither the clearance nor the "t" may be as prescribed. While this appears complicated, many user-friendly computer programs are available. It should be noted that these programs provide information on protein catabolic rate, which in stable patients, is equivalent to dietary protein intake. It is important for social workers to know something about each type and its setting. Patients will want to work with the health care team in choosing the modality that will best meet their needs. A patient may choose one type of dialysis or setting and later find that another type might better meets his or her needs. In helping patients make any decision about treatment type and setting, social workers should facilitate a review of the pros and cons of each choice and how each choice could affect the patient. A number of studies conclude that the more responsibility a person takes for his or her care, the happier and healthier he or she will be. This section has been divided into two parts: (1) the types of dialysis treatments and (2) the treatment settings. During a treatment, all the blood in the body travels several times through a filter, called a "dialyzer. To have a hemodialysis treatment, the patient sits in a recliner chair next to a hemodialysis machine. The tubing takes the blood through the filter (artificial kidney) for cleansing and returns it to the body. Only about 2 cups of blood are outside the body at any one time so the patient does not feel weak. At the end of the treatment, all blood is returned to the body and the needles are removed. Each person has his/her own needles, tubing, and filter which are attached to the dialysis machine and utilized for that particular treatment only. The patient is not at risk of getting a blood-borne disease while on hemodialysis. Numbing the skin or placing the needles into the vein can cause brief discomfort, but cleaning the blood is not painful. Treatments for chronic hemodialysis can be in a clinic that may be in a hospital or an outpatient setting. The team will work with the patient to determine the right schedule, diet and type of dialysis. The hemodialysis regime can vary: daily, overnight, and home hemodialysis are also available patient treatment options. Research suggests that hemodialysis received more frequently than three times a week Standards of Practice for Nephrology Social Workers (6th Ed. After a year of this randomized clinical trial, patients who received more frequent dialysis were found to have lower mortality rates and better cardiac status. In his meta-analysis of the research related to the benefits of home hemodialysis, Rosner (2010) concludes that patients who receive hemodialysis at home rather than in a dialysis center have significantly better outcomes, including improved mortality, morbidity, nutritional status, and quality of life. This and other research that evaluates the benefits of home hemodialysis suggests that the improved outcomes related to this treatment modality can be attributed to the longer dialysis treatment times that home hemodialysis patients usually receive, compared to patients who dialyze in outpatient centers only three times per week. Home hemodialysis is a treatment option that allows patients to perform their own dialysis at home. Patients and one social support network member receive comprehensive training to master their own hemodialysis. Dialysis centers arrange for equipment and supplies needed for home hemodialysis to be delivered and set up, using the small hemodialysis machines that the technology related to this modality now supports. Patients are trained to insert their own hemodialysis needles, set up and run hemodialysis machines, and troubleshoot any concerns. Patients can dialyze in the comfort of their homes, or perform hemodialysis when travelling. Patients who receive home hemodialysis see the members of their dialysis teams when they return to the dialysis clinic for routine laboratory testing and follow up visits. This is called an "access" because it provides a way to get the blood outside the body to cleanse it. A vascular surgeon who specializes in blood vessel surgery performs the operation. The procedure is done several weeks before dialysis is necessary, in order to give the vessel time to develop and heal. Types of Access Used in Hemodialysis Permanent: A fistula is an artery and vein that are joined under the skin. This allows a large amount of blood flow into the vein, making the vein grow large enough to place the needles required for hemodialysis. Although some patients never have clotting problems, others have a constant battle with clots that grow within the fistula or graft. These clots are not life threatening because they do not move to the heart or lungs. However, they have to be found and surgically removed quickly after they form or they will permanently block Standards of Practice for Nephrology Social Workers (6th Ed. To make sure blood is flowing through the vein, the patient checks the area daily by either lightly touching the area (to feel for a pulse, called a bruit) or by listening to the bloodflow through a stethoscope. To avoid this, the skin over the access will be cleaned thoroughly before needles are inserted. The patient should save the access arm just for dialysis and avoid anything that puts pressure on the access since extended pressure could cause clotting. The patient should not let anyone draw blood from his or her access arm nor utilize it for taking blood pressure. Usually this type of catheter is limited to those patients who cannot get either a fistula or a graft to work successfully. Temporary: Subclavian catheters are plastic tubing placed in a large vein near the collarbone. The tubing is inserted with local anesthetic in surgery or in an outpatient department. Research suggests that patients who receive peritoneal dialysis instead of in-center hemodialysis have better outcomes, including improved mortality and morbidity rates. A study of 9,277 dialysis patients from across the United States demonstrated that peritoneal patients have a 40% decrease in risk of mortality compared to patients who received hemodialysis three times per week (Charnow, 2010). Interestingly, a recent anonymous survey of nephrologists suggests that the overwhelming majority of nephrologists would choose peritoneal or home hemodialysis if they themselves needed renal replacement treatment (Schatell, Bragg-Gresham, Mehrotra, & Merighi, 2010). When asked what treatment modality they would choose for themselves if they had kidney failure and a five year wait for a kidney transplant, only 6. Forty-five percent of the doctors responded that they would choose peritoneal dialysis for themselves, and 45% responded that they would choose home hemodialysis. The peritoneum is a thin membrane that lines the wall of the abdomen and the digestive organs (including the liver, stomach and intestines). The peritoneal membrane is a lining with tiny openings like the hollow tubes inside a dialyzer. When a special dextrose dialysis fluid is placed inside the peritoneal cavity, the membrane acts as a filter. Waste products and extra fluid from the blood pass through tiny holes in the filter (the peritoneum) into the dialysis fluid. The wastes and fluid are removed from the body through a catheter and then thrown away. The catheter leaves the body in the lower abdomen, about 1 inch below and to the side of the navel. This area around the catheter is called an "exit site" and provides the pathway through which dialysis fluid can be placed. The nurse will give the patient safe, simple instructions for cleaning the exit site. Once the area is dry, many people fasten the catheter with a small piece of tape to the abdomen. The catheter is not removed between treatments and, if cared for, can last for many years. It does not prevent a patient from continuing his or her normal lifestyle or activities. The empty bag is for draining the used dialysis solution from the peritoneal cavity. When the abdomen is empty, it is filled with the fresh dialysis solution from the full bag. Waste products pass from the blood through the peritoneal membrane and into the dialysis fluid. The dialysis solution is left in the peritoneal cavity for four to six hours to collect wastes from the blood. Each time the patient changes the fluid and repeats the steps of draining out the old solution and replacing with the new solution, an "exchange" has been completed.
