An international standard exists for the identification of oxygen cylinders neoplastic arthritis in dogs cheap 400mg trental with visa, which specifies that they should be painted white. Cylinders of industrial oxygen should also be identified clearly, but this is not always the case. Never use any cylinder to supply gas to a patient unless you are sure of its contents. You must have in place an entire functioning system, comprising not only the apparatus for oxygen delivery, but also people who have been trained to operate it and a system for maintenance, repair and supply of spare parts. Safe use of oxygen cylinders the oxygen supply from a cylinder must be connected through a suitable pressure-reducing valve (regulator). When connecting a cylinder to the anaesthetic apparatus, make sure that the connectors are free from dust or foreign bodies that might cause the valves to stick. Never apply grease or oil, as it could catch fire in pure oxygen, especially at high pressure. Remember that an oxygen cylinder contains compressed oxygen in gaseous form and that the reading on the cylinder pressure gauge will therefore fall proportionately as the contents are used. A full oxygen cylinder normally has a pressure of around 13 400 kPa (132 atmospheres, 2000 p. It should always be replaced if the internal pressure is less than 800 kPa (8 atmospheres, 120 p. In use, they should be securely fixed in the vertical position to a wall or be kept standing secured with a restraining strap or chain. Supplies, equipment and maintenance Compressed oxygen is expensive and using it may pose logistical and cost problems for small or remote hospitals. In the United Republic of Tanzania, for example, a recent survey showed that 75% of district hospitals had an oxygen supply for less than 25% of the year. A reliable system for cylinder oxygen depends on a good source of supply and reliable year-round transportation. In many countries, oxygen cylinders must be bought rather than rented and frequent losses of cylinders in transit impose additional costs. Fortunately, since oxygen is needed for a variety of industrial as well as medical applications, it is widely available. Because cylinders of industrial oxygen and of medical oxygen are produced by the same process (the fractional distillation of air), good-quality industrial oxygen is perfectly safe for medical use. It may also be easier to obtain and less expensive, since a price premium is often levied for medical-grade oxygen. However, if you obtain oxygen from an unorthodox source, you must check it for purity before use (a portable analyzer may be used). Efficient and economical use of oxygen while still ensuring that the patient receives the maximum benefit is important. The oxygen concentration of air (21%) generally needs to be increased only to about 40% in order to bring great benefit to the majority of patients who need extra oxygen. They provide oxygen more cheaply than cylinders, as well as making oxygen available in hospitals where a regular supply of cylinders is difficult to obtain. It is strongly recommended that only those models listed by the World Health Organization as suitable should be purchased for use in district hospitals. Oxygen concentrators designed for use with individual patients normally give a flow rate of up to 4 litres per minute of near-pure oxygen at relatively low pressure. This oxygen can be used in exactly the same way as oxygen from a cylinder: As the supply for T-piece enrichment into a draw-over system For use with a nasal catheter, prongs or face mask to give postoperative or ward oxygen. Oxygen concentrators have been installed in many hospitals where cylinders are not consistently available. Concentrators ensure a more reliable and lower cost supply of oxygen than cylinders. The oxygen produced by concentrators is at least 90% pure and can be used in the same way as oxygen from cylinders, with the same beneficial effects. For successful use in a district hospital, a concentrator must: Be capable of functioning in adverse circumstances: Ambient temperature up to 40 C Relative humidity up to 100% Unstable mains voltage Extremely dusty environment Be incapable of delivering an oxygen concentration of less than 70% oxygen 15?10 Anaesthetic infrastructure and supplies Have a comprehensive service manual Have a supply of spare parts for two years use. A hospital planning to use oxygen concentrators should consider buying at 15 least two. Remember that no piece of equipment will last for ever, especially if it is neglected. Hospitals need to plan for regular maintenance usually after every 5000 hours of use. Servicing the machines is not complicated and can, if necessary, be carried out by the user after simple training. It is important to distinguish between gas mixtures that can burn and those that are explosive. Of the inhalational anaesthetics mentioned in this book, only ether is flammable or explosive in clinical concentrations: Mixtures of ether and air in the concentrations used for anaesthesia are flammable Mixtures of ether and air (whatever the concentration) are not explosive Mixtures of ether with oxygen or nitrous oxide are explosive Other substances used in the operating room, such as alcoholic skin preparations, also present a risk of fire or even explosion in the presence of high concentrations of oxygen. There is no site within the draw-over apparatus or breathing system where a fire or explosion could start. When flammable gases are in use, the most likely sources of combustion in the operating theatre are the surgical diathermy machine and other electrical apparatus. Static electricity is unlikely to start a fire, but may trigger an explosion if an oxygen-rich gas mixture is present. To minimize the risk of explosion, never allow the simultaneous use of diathermy on a patient anaesthetized with ether. If one of these techniques must be used for the benefit of the patient, the other must not be allowed. This is important in a dry climate, but less so in a humid one where a natural coating of moisture on objects prevents the buildup of static. Make sure that no one stands on the hose and that there is nothing that could trigger combustion near the end of the tubing. No potential cause of combustion or source of sparking should be allowed within 30 cm of any expiratory valve through which a potentially flammable or explosive mixture is escaping. Each year more than two million first few hours after the injury is people die as a result of injuries caused by violence. Among people aged 15?44 years, Your hospital should have a interpersonal violence is the third most common cause of death, suicide the trauma system, such as fourth and war the sixth. In addition to injuries and death, violence can result Primary Trauma Care, to ensure that life-threatening conditions in a wide variety of health problems. These include profound mental health can be quickly identified and problems, sexually transmitted diseases, unwanted pregnancies as well as treated behavioural problems. Hospital staff should be trained in acute trauma care, which Throughout the world, injuries have become a major public health problem. In industrialized countries, intentional and unintentional (accidental) injuries have become the third most common cause of overall mortality and a main cause of death among the 18?40 year old age group. Medical and nursing teams are in a unique position to educate patients and health workers about effective ways of preventing injury. The Primary Trauma Care Manual provides a foundation on which doctors and nurses can build the necessary knowledge and skills for trauma management with minimal equipment and without sophisticated technological requirements. Factors given special consideration in the Primary Trauma Care Manual include: the great distances over which patients may have to be transported to reach hospital the time taken for them to reach hospital Possible absence of high-technology equipment and supplies Possible lack of specialists in trauma care at district hospitals. These strategies are not easy to implement and success in trauma prevention in an area depends on many factors, including: Culture Availability of personnel Politics Health budget Training. Immediate deaths Patients who do not reach the hospital alive die from overwhelming injuries, including: Rupture of the heart or pulmonary artery Overwhelming haemorrhage Massive destruction of brain or other neural tissue. Many deaths in the early time period are preventable with appropriate early diagnosis and treatment of severe life-threatening injuries such as: 16 Pneumothorax Flail chest Abdominal haemorrhage Pelvic and long bone injuries. However long since the injury, trauma care must start immediately the patient arrives. B is for Breathing Even with an open airway, no oxygen reaches the lungs unless the patient is breathing or someone provides artificial ventilation of the lungs. Breathing may stop because of severe head injury, hypoxia, mechanical or circulatory arrest. C is for Circulation Oxygen in the lungs cannot reach the tissues unless the heart is working; common reasons for inadequate circulation include blood loss (shock) and increased pressure on the heart from pneumothorax or haemopericardium. Shock and low blood pressure are dangerous for all patients, but especially for patients with head injury, as the blood supply to the brain will be further reduced. This causes a vicious circle in which hypoxia causes further brain swelling which, in turn, reduces the flow of blood to the brain. D is for Disability and neurological Damage (brain and spinal cord) Checking for neurological damage is a vital part of the primary survey.

If during a primary or revisional total hip replacement arthritis medication south africa cheap trental 400 mg with mastercard, an acetabular or femoral bone graft, using either morcellised bone or block of bone, is performed in addition to the joint replacement the following codes must be assigned: Primary or revisional total prosthetic replacement of hip joint code W31. For the second stage of the procedure assign the following codes: Insertion of like for like prosthesis: Revision of prosthetic replacement of relevant joint code Y71. The removal of the joint spacer during the second stage of the procedure must not be coded in addition. First the prosthesis is removed, surrounding infected tissue is debrided and an antibiotic joint spacer is inserted. After the infection has cleared the joint spacer is removed and the new joint prosthesis is inserted, the new prosthesis may be the same type, like for like, (for example, cemented to cemented) or a different type (for example, cemented to uncemented) to the prosthesis that was removed during the first stage. There are no dedicated codes for the removal of prosthetic joint replacements, therefore the relevant attention to codes must be used for the first stage. However, as revision and conversion to codes are available within specific joint replacement categories these are used for the second stage when a new joint replacement is inserted. Examples: A patient with an infected left cemented total knee replacement is admitted for the first stage of a two stage replacement. The joint spacer is removed and a new cemented total knee replacement is inserted: First stage: W42. The joint spacer is removed and a new uncemented total hip replacement is inserted: First stage: W39. It is not appropriate to assign an attention to code for the aspiration of a prosthetic joint. The presence of the prosthesis may be connected to the need for aspiration; however the aspiration is performed on the cavity of the joint, and does not involve the actual physical parts of the prosthesis. However it is possible to have a hybrid knee replacement with a cemented femoral component and an uncemented tibial component. Category O32 Total prosthetic replacement of ankle joint classifies all total prosthetic replacement of ankle joint whether cemented, uncemented or unspecified. The stump becomes infected and a further three inches of the femoral shaft are amputated. Following amputation the necrosis reoccurs in the leg and a further amputation is performed above the knee. The exception is fibrinolytic (clot busting) drugs on the National Tariff High Cost Drugs List. When intraoperative blood (cell) salvage and reinfusion of the salvaged blood cells into the patient has been performed during a procedure, the following codes must be assigned in addition to the code(s) classifying the procedure during which the cells were salvaged: X36. Codes within Chapter R categories R14 Surgical induction of labour and R15 Other induction of labour must be used to code induction of labour. In allogeneic transplants (where allogeneic means coming from the same species but genetically dissimilar), patients can receive stem cells from their brother or sister (which would include non-identical twins) or parent. Cells from a person who is not related to the patient (an unrelated donor) may also be used. Any procedure(s) performed in order to carry out a procedure classifiable to category X40, such as insertion of dialysis catheters, central venous catheters, arteriovenous shunts, etc. The removal of organs for donation from brain dead or deceased patients must not be coded. The type of anaesthetic given may be coded in addition if this information is required to be collected locally. These are typically immobilisation devices such as impression and shell fitting, lead cut-outs, mouth bites and beam shaping devices. Delivery of radiotherapy Radiotherapy delivery is coded using the following methods: Coding radiotherapy delivery using body system chapter codes Where a body system chapter code that classifies radiotherapy is available. Coding radiotherapy delivery using codes from Chapter X Where a body system code is not available, the following codes and sequence must be applied: X65. A prescription specifies a dose and fractionation for a series of identical treatments. Different anatomical sites treated concurrently would have separate prescriptions. Codes within category X67 Preparation for external beam radiotherapy are divided into simple and complex. Clinical Coding Departments must liaise with clinical staff to determine what actual techniques would fall into these two categories, but for information purposes the following advice is given: Simple radiotherapy is a standard technique with standard imaging and dosimetry. These techniques are relatively easy to plan and the dosimetry is straight-forward. Any deviations from this standard planning protocol may fall into the complex subcategory because they will be out of the norm, need more consideration and be more time consuming on the part of the dosimetrist. Brand names should not be confused with the actual type of stereotactic radiation. High dose rate brachytherapy is delivered through temporarily placed applicators in a shielded room. Multiple fractions may be given and patients may attend the unit more than once in a day. Pulsed dose rate brachytherapy is delivered through temporarily placed applicators, however the radiation dose is given over many hours in short pulses. Examples: Preparation and delivery of pulsed dose brachytherapy therapy for prostate cancer X68. Codes in categories X70?X74 must only be assigned for patients receiving chemotherapy in the treatment of malignant or in-situ neoplasms. Codes classifying high cost drugs must be assigned in preference to other codes in Chapter X which classify method of administration. However if a high cost drug is injected into a specific site classifiable to a body system chapter (such as a sweat gland), then a body system chapter code must be assigned. In many cases a note exists at category or subcategory code level within the main body system chapters indicating that a code from Chapter Y is required, however these codes can also be assigned to codes where one of these notes is not present. Codes in Chapter Y must only be used in a secondary position following a code from the body system chapters (A?X). Where a number of procedures have taken place using different methods of approach a code from categories (Y46?Y52 and Y74-Y76) must be assigned after each body system code. Examples: Open biopsy of lesion of frontal region of brain through frontal burrhole A04. Y53 Approach to organ under image control Codes in category Y53 Approach to organ under image control are used as additional codes for any procedure that uses image control that may or may not be performed via percutaneous approach. This excludes those procedures performed using an arteriotomy approach under image control (Y78). The exception to this is fluoroscopy when used with an image intensifier, where it is only necessary to assign code Y53. Y78 Arteriotomy approach to organ under image control Codes within category Y78 Arteriotomy approach to organ under image control must only be used where it is clear that an arteriotomy approach using image control has been performed. Common terms which indicate an arteriotomy has been performed are: incision into artery, surgical cut-down or cutting of artery. The arteriotomy will always require closure with either suture or clips to the overlying skin 152 Subsidiary Classification of Methods of Operation and this must not be coded in addition. The majority of interventions that are undertaken on arteries by radiologists and some surgeons are referred to as Interventional Radiology procedures and are minimally invasive. These are usually undertaken by putting local anaesthetic in the skin and then passing a small needle and tube into the artery without a surgical incision. This is referred to as a percutaneous access and the intervention is classed as a percutaneous transluminal procedure. Once inside the artery, the radiologist or surgeon needs a means of visualising the artery and this is achieved by using image control. An arteriotomy is a method of approach used to gain access to the inside of the artery by surgical incision. Most patients having an arteriotomy will have a treatment that does not require image guidance as the surgeon will have a direct view of the artery. However, some interventions, in particular stent grafts for aneurysms, require incision away from the site of the procedure, and therefore require some form of image control to allow precise visualisation. Examples: Percutaneous transluminal ablation of ventricular wall under image conrol K57. In all other cases anaesthetics may be recorded if this information is required to be captured locally. It is regarded as best practice to record epidurals or spinals performed on obstetric patients. Where a code from categories Y95 and Y53 are both required the code from category Y53 must be sequenced before the code from Y95.

Those with peritonitis rheumatoid arthritis 400mg trental with amex, per foration, or signs of ischemic bowel are immediately prepared for laparotomy with expeditious correction of fluid and elec Radiographic Studies trolyte deficits. A urinary catheter is inserted to guide resus citation with the end points being resolution of tachycardia Plain Radiographs and hypotension and/or achieving a urine output of at least 0. A formed in most patients suspected of having small bowel nasogastric tube is inserted preoperatively to decompress the obstruction and consists of both upright and supine abdomi stomach, because these patients are at risk for aspiration on nal films and an upright chest X-ray. Patients with par absent, however, when the obstruction is proximal or the tial small bowel obstructions secondary to adhesions will dilated bowel loops are mostly fluid filled. The findings of pneumatosis intestinalis plete obstruction is significantly lower. This is in part attributable to the fact that mary imaging modality in patients suspected of having small long tubes with mercury-weighted tips (Miller-Abbott) are no bowel obstruction. Postoperative Complications 149 expertise, serial radiographic studies, or endoscopy to guide vomiting and distension is pathognomonic for partial small insertion. The onset of flatus, however, usually sig the use of nasoenteric tubes, mostly among radiologists. Narcotic analgesics may be administered to comfort the After the adequacy of resuscitation is confirmed and broad patient, but not to the point of diminishing mental status. The spectrum antibiotics active against enteric pathogens are practice of withholding pain medication to avoid masking the administered, the peritoneal cavity is entered through a mid signs of perforation or ischemia is probably unnecessary. This is a point in the operation where the risk of Serial abdominal examinations (ideally just before the next inadvertent enterotomy is very high because bowel loops are dose of analgesics) should be performed to assess for increas distended and often adherent to the undersurface of the ing tenderness or the presence of peritoneal signs. In general, rather than a cutting stroke, is used to breach the peritoneal a nonoperative course may be followed for 24?48 hours. Using this technique, it is usually possible to recognize obstruction has not resolved within that time period, it is an adherent bowel loop before enterotomy occurs. In the most favorable scenario, a single constricting band will be encountered that can be sharply divided to relieve the obstruction. In the worst cases, the peritoneal cavity will be Decision to Operate totally obliterated by scar tissue. An orderly and systematic Several studies have attempted to define certain criteria that approach to adhesiolysis is advised in these instances. First, would reliably predict the presence or absence of strangulated the underside of the midline scar is cleared so that the entire bowel. Unfortunately, none have been shown to be particu length of the incision can be opened if necessary. Next, adhe larly accurate and the best tool remains sound clinical sions to the abdominal wall are dissected laterally until both judgment. Certainly, patients with fever, peritonitis, pneumo paracolic gutters are reached. This will allow the placement of peritoneum, or overt sepsis should undergo emergent laparo a self-retaining retractor to facilitate exposure. In cases in tomy because these are hard signs of transmural bowel which bowel distension is severe, needle decompression may necrosis. The presence of early ischemia, however, is much be used to gain additional working space. It is not uncommon for patients with adhesions that defy identification of the bowel and peritoneal small bowel obstruction to present with tachycardia, relative surfaces (?frozen abdomen) may be injected with saline hypotension, mild acidosis, and leukocytosis, all of which through a fine-gauge needle to separate the surfaces and thus may be secondary to dehydration. Attention is then turned to the pelvis aggressively rehydrated with isotonic intravenous fluids and where the most difficult adhesions are often encountered. Persistence of any Rather than separating individual bowel loops at this stage, of these signs after fluid resuscitation should prompt immedi the small bowel residing in the pelvis should be mobilized ate laparotomy. Adherence to this simple algorithm should en-masse by lysing adhesions to the pelvic structures in an minimize the progression to strangulation while limiting the anterior to posterior manner in order to roll the mass of intes number of unnecessary laparotomies. The final portion of this stage of Distinguishing between partial and complete obstruction is the operation involves mobilizing the plane between the small also a key element in deciding which patients should be taken bowel mesentery and the retroperitoneum until the duodenum for early operation. Only at this point are all adhesions between tion of a complete obstruction with expectant management is individual bowel loops lysed in order to free the entire length low (20%). The bowel is then inspected for any strangulation or perforation has occurred will substantially coexisting pathology and for enterotomies or serosal tears increase the mortality rate. The Assessment of bowel viability is usually possible by using passage of stool or flatus cannot be relied on as an accurate the triad of color, peristalsis, and mesenteric pulsations. In predictor because patients with complete obstruction may cases in which these signs are questionable, the ischemic seg continue to pass stool and flatus until the bowel distal to the ment should be wrapped in warm, wet packs and viability site of obstruction is evacuated. If viability is still in doubt, use of more than 12 hours after the onset of obstructive symptoms, the Doppler probe or systemic injection of fluorescein dye the likelihood of complete obstruction is diminished. If an exten adhesion and healing of the staple lines of the linear cutter sive segment of questionable viability is present, then a sec between the limbs of a functional end-to-end/side-to-side ond-look operation 24 hours later should be planned before anastomosis. This is best prevented by maximally distracting committing the patient to a massive small bowel resection. It is our policy to divide the majority of adhesions be easily diagnosed with a water-soluble contrast study, espe if this can be done safely. This will facilitate inspection of the cially if administered via a long tube near the point of entire length of the small bowel and allows for the placement obstruction. The treatment should be conservative initially of anti-adhesion barriers if desired (see below). In some cases, the balloon-tipped catheter itself has broken through the healing web and relieved the obstruction. In the case of an obstructed Special Situations ileocolic anastomosis, colonoscopic balloon dilatation may be carefully used. Operative intervention should be a last resort Early Postoperative Bowel Obstruction and usually requires resection and reanastomosis. Early postoperative bowel obstruction is generally defined as mechanical obstruction occurring within 1 month of abdomi Prevention of Adhesions nal or pelvic surgery. This condition is special in that attempts at relaparotomy in the early postoperative period frequently More than 90% of patients undergoing abdominal surgery result in disastrous complications. Once an area of injury is response usually begins within the abdomen at 7?10 days established, fibrin is deposited and then organizes to form a postoperatively and persists for at least 6 weeks. Bowel motility and endoge operate during this period of time, the surgeon is likely to nous lubricants attempt to counteract this process, but in most encounter dense hypervascular adhesions that may obliterate cases, adhesions will eventually result as the deposited colla the peritoneal cavity. Therefore, immediate reoperation for early post vent, or influence adhesion formation.

If resolution does not occur within the first 5?7 severe adhesion formation can be anticipated, for instance days, a percutaneous gastrostomy tube may be placed for patients with multiple recurrences of small bowel obstruction, longer-term decompression, and the patient is started on the use of long intestinal tubes placed at the conclusion of sur hyperalimentation. Patients may be discharged from the hos gery to splint the bowel open during adhesion formation pital on this regimen and laparotomy performed in 6 weeks if has been advocated. The best studied of these is a by an enteric leak can be percutaneously drained and a con bioresorbable membrane of modified sodium hyaluronate and trolled enterocutaneous fistula established. A large multicenter study by Becker usually only required in cases of ischemic or necrotic bowel. The use of adhesion barriers in patients at high risk Anastomotic Overhealing for subsequent reoperation because of disease or previous Anastomotic overhealing is a rare cause of postoperative adhesions may be justified by the likely improvement in the small bowel obstruction. It is most often attributable to early ease and safety of the subsequent abdominal reentry and 10. One of the problems with the barrier material is single-agent or combination choices exist, each with adequate that it only prevents adhesions between the surfaces where gram-negative and anaerobic coverage.
