G, if the patient is too weak to sit up, you the cricothyroid approach using a large tube. Use humidified the prone position with a pillow under the hips and the foot of the inspired air normally without the need for sedation or bed raised. Percuss the thorax position, because this restricts movement of the over a towel or blanket with your cupped hands for periods diaphragm, and promotes the collapse of the lower lung of about 1min. Relax during inspiration, and follow this with Insist on early mobilization by the 2nd day, if you can, some deep breathing. Distinguish between an effective deep are worst, and arrange the patient so that this affected part productive cough (which is what you want) and a noise in is uppermost, using the appropriate position (11-24). If there is Suggest taking a deep breath after each cough, and not to established collapse or infection repeat this bd/tds. If the patient is too ill for the hips to be raised, lay him If there is an abdominal wound, it is essential to bend on his side. Huffing, when the lungs are in full inspiration, to promote the drainage of secretions from particular parts of the lung. Study the chest radiograph, and decide which position will be will dislodge secretions from the larger airways.

If it is abnormally tender and indurated, near-by, suspect peritonitis and re-open the abdomen; associated with fever, it is probably infected. Sometimes the site of infection in a suture closing the abdomen, this is how the problem may be unclear. If many of your wounds become infected, look at your sterile procedures and leave any but completely clean If the wound is tense, swollen & bruised, with old blood wounds open (11. If it is clean after pus, it is infected, so start by removing 1-3 skin sutures on 5days, consider secondary suturing. This is ketamine or diazepam, and press the sides of the wound, commoner than you probably think. Its best to use a 10ml syringe with a 24G needle attached: break off the needle from the If the wound discharges chronically, there is probably a plastic hub: the resulting apparatus will produce the ideal foreign body in situ. If the discharge persists, up the cleansing of a wound by applying a suction there may be a fistula (11. You can make your own by should have a radio-opaque marker), and re-explore the simply placing a fenestrated drainage tube, attached to a abdomen carefully. Bowel may be caught in the swab, and suction device, between layers of gauze and sponge, need resecting en bloc (11-7). The seal must be air-tight, and you therefore need to make sure the surface is quite dry 11. There is severe intra-abdominal sepsis, such as an infected Caesarean Section, typhoid peritonitis, or a perforation of the large bowel. There is a chronic pressure on the wound from prolonged coughing, asthma or chronic obstructive airways disease. An abdomen which bursts some days after you have sewn it up is a tragedy, because it is often preventable, and because there is a 30% chance of death if subsequent treatment is delayed. You suture the abdomen with non-absorbable, such as steel, nylon, or polyethylene. You close its muscles with interrupted through-and-through sutures, which are not too tight and take wide bites of tissue (11. If the wound is painful about a week after the operation, and there is a thin reddish-brown discharge, the abdomen is probably going to burst. Decompress the bowel by inserting a nasogastric tube, administering a rectal enema. A, measure the defect after debridement, and approximating the wound edges without excessive tension. B & C, incise the transversus abdominis and internal oblique with diathermy along a line between the mid- axillary and anterior axillary line. World J Surg 2006;30(6):1065) E, tension sutures cutting out as the intra-abdominal pressure rises. An intestinal fistula is an abnormal track, usually lined by If you confirm a burst abdomen, remove all sutures from granulation tissue, between the bowel and the skin. Gently separate the parietal peritoneum Fistulae are unusual but serious complications of and the underlying bowel and omentum. Check if there is any evidence of intra- actinomycosis or Crohns disease arise spontaneously. Beware of postoperative fistulae: If there is any tension when you try to pull the (1);After you have divided adhesions for intestinal abdominal wound edges together, measure the width.

There are no bony changes If he complains of a trigger finger or thumb so that cheap diovan 40mg amex, for about 2wks generic diovan 80 mg line. The powerful flexors are more difficult to distinguish clinically and by radiography. If you see the disease early, inject the thickened tendon sheath with 05ml lidocaine/hydrocortisone mixture using Suggesting rheumatic fever: age 5-20yrs. Bone erosion around the If injection is not successful (50% of cases), apply a acetabulum (appearing to enlarge upwards), often with tourniquet and get fine instruments. Use a fine tenotomy knife to make a longitudinal incision in the sheath to release the tendon. Suggesting rheumatoid arthritis: from childhood to Leave the sheath open, suture the skin only, and start 40yrs (at the onset). Flex the wrist over the edge of a table; this will carefully: some children develop Perthes disease later. The median nerve passes through the carpal tunnel on the palmar side of the wrist. It causes: (1);Pain, paraesthesiae and reduced sensation in the distribution of the median nerve (her thumb, the index and the middle finger, and the radial side of the ring finger). C, median nerve with an annular passes medial to the anterior superior iliac spine, and so constricting ring round it, caused by pressure from the edge of the may be entrapped under the inguinal ligament. Hang the arm up on a support, and watch the (1) Wasting of the muscles of the thenar eminence. Incise longitudinally for 4cm in the thenar crease, and then transversely for 2cm in the wrist crease. A patient with leprosy can lose feeling in the hands Look for the median nerve, but do not injure it! Do not close the and cuts cause scars that progressively destroy the pulps of deep tissues. Persuade him that it is the injury to the hands which leads to wounds, and not the disease itself. If he fails to care for the fingers, and presents you with a severely disabled hand, there is little you can do, except to maintain such mobility as there is with physiotherapy. Patients are usually able to use their deformed hands quite well, and do not like having their fingers amputated. Tendon transfers and arthrodeses are sometimes helpful, and you can make a Z-plasty to widen the web of the thumb, but these are not easy operations. Ensure that all the joints of the hand are put through their full range daily, using the exercises (32-37D,E). If the ulnar nerve is acutely involved, rest the arm in a sling with the elbow at 90, and put the whole arm through its full range of motion at least once a day. If the lumbricals are involved, there is danger of development of a claw hand, so teach the exercises described (32-37F,G). If paralysis is chronic and slowly progressive, recovery is unlikely, so insist on exercises (32-37A): a paralysed hand is more useful if it is mobile rather than Fig. Tenderness is often absent Protect the patients hands during hard work, either by and fluctuation is too late to be useful. The first complaint making sure he wears protective gloves, or by adapting the may be painful glands in the axilla. If he smokes the pain which prevents a normal person from using the (persuade him not to) he must use a cigarette holder. Make sure that the insensitive hands are soaked and oiled So make sure that a leprosy patient rests an infected hand, in the same way as the feet (32. Rest is essential: antibiotics on their own Use plaster strengthened with a stiff longitudinal wire, are inadequate. Observe the finger If infection starts as a macerated skin crease in a carefully for blueness. Initially, remove splints at night, paralysed finger, splint it with a posterior splint in just until you are sure they are not occluding the circulation. If the dorsum of the hand is scarred, so that the mcp If there is any discharge, add an antibiotic. This can happen as the result of a lepra reaction, If there is septic tenosynovitis, it is likely to be the result when a thick sheet of inflammatory tissue scars and of spread from a pulp infection. If you feel rough bone at the bottom of a sinus over the tip of the finger, this is osteomyelitis of the terminal If the little finger is badly deformed, remove it with half phalanx. Splint the hand and fingers as nearly as possible If the septic arthritis does not heal, excise the joint. Immobilize the infected joint for at least and any dead tissues, and splint the joint in a position of 4-6wks after the infection is controlled, and the ulcer function (7.

Remove the tourniquet (if present) buy 160 mg diovan overnight delivery, control bleeding generic 40mg diovan overnight delivery, drain and close the stump with the suture line lying posteriorly (35-19F). Then bring the patellar tendon round so you can fix the undersurface of the patella to the bony stump of the femur. The best length of stump for a prosthesis is 12-18cm E, suture the patellar tendon to the anterior cruciate ligaments. A stump of only 6cm slips too easily out Get your assistant to hold the knee half-flexed. Lift the edge of the posterior flap and divide the medial hamstrings from the tibial tuberosity. Do not amputate below the muscle area of the calf, This exposes the main trunk of the popliteal artery: because the tissue here has a poor blood supply. Behind the artery, find the tibial nerve, draw it gently into Do not amputate below the knee if there is a fixed flexion the wound, and cut it clean (35-19D). Divide the popliteral artery below its superior popliteal pulse is not palpable as the flap will depend on genicular branches which supply the soft tissues of the the profunda femoris artery. Instill an enema before operation to empty the rectum if it It is important that there is absolutely no tension in is full. Suspend the knee over an anaesthetic screen bar for ready If there would be tension at this point, divide the tibia access; if you cannot do this, place an inverted bowl under and fibula higher up; you may find you have to divide the the lower leg. Prepare the skin right up to the groin, in case vessels and nerves again higher up also. If a haematoma forms within the wound, open it up as If you are not certain of the geometry of the flaps, much as necessary and evacuate the haematoma, otherwise cut them too long rather than too short. Start the skin If the wound becomes septic, open it up and debride any incision anteriorly at this point and continue transversely dead tissue; you may need to re-fashion the stump if there round each side of the tibia of the way round; is enough length. However, it usually means making a then continue down the leg the same length (usually 4cm through- or above-knee amputation. This time, use delayed below the anterior incision), and finally join both incisions primary closure. If bone protrudes through the stump, re-fashion it If a long posterior flap is not possible because of making sure the tibia is bevelled and the myoplastic flap is dubious skin vascularity, the skew flap is an alternative. In fact, the skew flap is actually a short make a through-knee amputation, or cut the stump even posterolateral and a longer anteromedial flap based on a shorter and then fit a peg leg. If at this point you find ischaemic or infected tissues, proceed immediately to a through- or above-knee amputation. Take the lateral incisions down to deep fascia, and the anterior incision straight down to the tibia and the interosseous membrane. Strip the periosteum off the tibia for 2cm above the point of division and divide it obliquely with a saw, preferably Giglis; then clear the fibula 2cm above the level of the tibial division, and divide it with a saw. Hold the distal tibia forwards with a strong hook inside its medullary canal, and expose the posterior tibial and peroneal vessels lying under tibialis posterior; ligate and divide these and cut the posterior tibial nerve clean, allowing it to retract. Then slice obliquely through the calf muscles to reach the posterior skin incision; a large sharp amputation knife is best for this, giving a clean cut. You need to remove all the bones of the foot and saw off the malleoli, so that the end of the tibia is flat. Then you remove a large full thickness heel flap subperiosteally from the calcaneum, and bring it forward to make a solid covering for the end of the tibia. It is sometimes indicated in leprosy with very distal ulcers under the heads of the metatarsals. This is an excellent amputation if it is well done, but it is also the most difficult of the amputations we describe. Its advantage is that if the front of the shoe is filled with cotton wool, a patient can walk reasonably well without a prosthesis. A metatarsal amputation, however, is one of the less useful amputations; its main use is in crush injuries of the toes. Then, bring the incision vertically under the sole of the foot to the tip of the medial malleolus. Put a knife into the ankle joint between the medial malleolus and the talus and cut the deltoid ligament. Forcibly plantarflex Do the same on the lateral side and cut the calcaneo- the foot and cut all anterior structures down to the bone. Then cut the calcaneum out of the heel, (2) Prevent the heel pad from tilting out of alignment with leaving behind the periosteum and specialized fibrofatty the tibia; this is a real disaster! Put the 1st piece on starting below the knee posteriorly, bring it round the flap, and then anteriorly, so as to flex the Pull the talus and calcaneum forward with a bone hook. Apply the 2nd strip from one side to Dissect posteriorly, and cut the posterior capsule of the the other. Check the strapping daily, to Achilles tendon about 10cm proximal to the heel flap.

Nit Removal Treatment with a pediculicide kills adult lice and nymphs preventing the spread of head lice infestation to other people 80 mg diovan amex. Removal of nits is recommended to reduce confusion about the effectiveness of treatment generic diovan 80 mg overnight delivery. Nits within 1 cm of the scalp should be physically removed by a fine toothed comb. A variety of agents are available to break down the cement holding the nit to the hair shaft including distilled white vinegar, formic acid preparations, and enzymatic nit removal systems. Nits that are present on the hair shaft greater than 1 cm from the scalp are not considered to be viable and do not have to be removed. It is also recommended that all hair care items and bedding belonging to the infested person be cleaned. Head lice should be sought in the hair while body lice will be found in the clothing, most commonly on the layer next to the skin. Given their limited and specialized habitat, surveys are not normally conducted specifically for human lice. However, if medical treatment is sought because of lice, qualified medical practitioners will examine the head and pubic areas for lice. Give special attention to seams of clothing, particularly trousers and to wool blankets for the presence of both lice and eggs. All management operations for individual treatments for lice infestations are directed and conducted by medical personnel. Mass delousing Bulk-issue louse powders are used in mass delousing with hand and power dusters. Use manual dusting 178 equipment such as plunger-type hand dusters to treat individuals without requiring clothing removal. To treat more than 10 to 12 people at a time, use power equipment if it is available. A power delouser has a small portable gasoline engine and air compressor, 10 lengths of hose and 20 dusters. It is easy to detach dusters and attach extra units to aid refilling while others are in use. Contingency considerations Individual protective measures against lice include issuing standard issue louse powder to individuals and properly laundering uniforms in a laundry unit. Use of a standard 0 laundry unit (operating at 140 F for 20 minutes) normally ensures that any nits and living forms are killed. Mass delousing is always indicated when louse-borne disease is endemic and either large numbers of prisoners of war or displaced persons come under U. Shaving of hair (head and pubic) can eradicate both the adults and nymph Review Questions 1. Draw the strategy of controlling the epidemic of relapsing fever in a certain community. They are oval in shape with no wing Shinny reddish to brown in color (after blood meal they become dark brown) 4 - 7 mm long. During the ten minute or so feeding period they take 2- 5 times their body weight blood from their host. Once fed, bugs return to the cracks behind wall paper, furniture and crevices in which they hide. Application of insecticide like Carbonyl, Propoxur, Deltamethrin, Bendiocarb Review questions 182 1. About 50 species have become domestic pests and the most important medically are Blattela germanica (the German cockroach), Blattella orientalis (the oriental cockroaches) and periplaneta Americana (the American cockroach). Cockroaches almost certainly aid in the transmission and harbourage of various pathogenic viruses, bacteria, protozoa and helminthes. In adults of both sexes there are two pairs of wings- they are not used in flight but serve as protective covers. Cockroaches are most readily distinguished from beetles by having the fore wings placed over the abdomen in a scissor like manner. Cockroaches are often seen running around with an ootheca partly protruding from the tip of the abdomen. Nymphs are hatching out from the eggs after about 1-3 months, depending on both temperature and species. The duration of the nymph stage varies according to temperature, abundance of food, and species. Nuisance- the presence of cockroaches in houses and hotels, etc has for a long time been regarded as highly undesirable because of their dirty habits of feeding indiscriminately on both excreta and 185 foods, and their practice of excreting and regurgitating their partially digested meals over food 2. Typhoid fever, diarrheal diseases, etc The presence of cockroaches in houses and hotels has for a long time been regarded as highly undesirable because of their dirty habits of feeding indiscriminately on both excreta and foods, and their practice of excreting and regurgitating their partially digested meals over food. Many of the parasites and pathogens isolated from cockroaches are spread directly from person to person with out the aid of intermediary insects because of this it is very difficult to prove that cockroaches are the prime cause of any disease out break. Nevertheless because of their unsanitary habits they have been suspected as aiding the transmission of various illnesses.
