On examination she has blurred disc margins and a degree of double vision especially on looking upwards. Consider reduction of intracranial pressure with agents such as intravenous mannitol. Assisted ventilation to induce hypocapnia can provide temporary fall in intracranial pressure. They can be remembered and classified according to where along the motor pathway the pathology exists.

Villous adenomas have been demonstrated to contain malignant portions in about one-third of affected persons and invasive malignancy in another one-third of removed specimens skin care at home proven decadron 4 mg. Anterior resection is performed for large lesions or those containing invasive carcinomas when the lesion is above the peritoneal reflection skin care md discount decadron 1mg line. Transrectal excision with regular follow-up examinations is sufficient for lesions without invasive carcinomas. The stone becomes lodged in the small bowel (usually in the terminal ileum) and causes small-bowel obstruction. Plain films of the abdomen that demonstrate small-bowel obstruction and air in the biliary tract are diagnostic of the condition. Treatment consists of ileotomy, removal of the stone, and cholecystectomy if it is technically safe. If there is significant inflammation of the right upper quadrant, ileotomy for stone extraction followed by an interval cholecystectomy is often a safer alternative. Operating on the biliary fistula doubles the mortality rate compared with simple removal of the gallstone from the intestine. The latter includes perforated diverticulitis with or without abscess and fistulous disease. Diverticular abscesses are treated with percutaneous drainage initially followed by definitive resectional therapy. Initial percutaneous drainage allows for a 1-stage procedure that consists of resection of the affected colon with primary anastomosis. Perforated diverticulitis is typically treated with either the Hartmann procedure (sigmoid resection with end colostomy and rectal stump) or sigmoid resection, anastomosis, and diverting loop ileostomy. A gallbladder ejection fraction of less than 35% at 20 minutes is diagnostic of biliary dyskinesia. Cholecystectomy results in improvement in symptoms in 85% to 94% of patients with biliary dyskinesia. A laparoscopic cholecystectomy should not be performed without confirmation of the gallbladder as the etiology of the symptoms. There is no role for oral dissolutional therapy with ursodeoxycholic acid in the treatment of biliary colic, since no gallstones are present. Patients with suspected gallbladder carcinoma should undergo cholecystectomy with intraoperative frozen section, and if there is invasion of the serosa and no evidence of metastatic or extensive local disease, they should undergo a radical cholecystectomy (portal lymphadenectomy and either wedge or formal resection of the liver surrounding the gallbladder fossa in addition to the cholecystectomy). Bile aspiration does not have a role in the workup of gallbladder polyps or gallbladder carcinoma. The hematoma typically presents as an abdominal mass that does not change with contraction of the rectus muscles. Management is conservative unless symptoms are severe and bleeding persists, in which case surgical evacuation of the hematoma and ligation of bleeding vessels may be required. It has the ability to exclude other diseases, such as tumors, and document the degree of peptic esophageal injury. Surgical treatment for sliding esophageal hernias (type I paraesophageal hernias) should be considered only in symptomatic patients with objectively documented esophagitis or stenosis. The overwhelming majority of sliding hiatal hernias are totally asymptomatic, even many of those with demonstrable reflux. Even in the presence of reflux, esophageal inflammation rarely develops because the esophagus is so efficient at clearing the refluxed acid. Symptomatic hernias should be treated vigorously by the variety of medical measures that have been found helpful. Patients who do have symptoms of episodic reflux and who remain untreated can expect their disease to progress to intolerable esophagitis or fibrosis and stenosis. Neither the presence of the hernia nor its size is important in deciding on surgical therapy. Once esophagitis has been documented to persist under adequate medical therapy, manometric or pH studies may help determine the optimum surgical treatment. A femoral hernia occurs through the femoral canal bounded superiorly by the iliopubic tract, inferiorly by Cooper ligament, laterally by the femoral vein, and medially by the junction of the iliopubic tract and Cooper ligament. This patient has no evidence of an acute incarceration and does not need emergent repair of her hernia at this time. It typically presents as a painful fluctuant mass extending from the midline and is located between the gluteal clefts.

The low urine output indicates poor renal perfusion skin care basics cheap decadron 8mg with mastercard, while the high urine-specific gravity indicates adequate renal function with compensatory free-water conservation acne tretinoin cream 005 discount decadron 4mg with amex. The administration of a vasopressor agent would certainly raise the blood pressure, but it would do so by increasing peripheral vascular resistance and thereby further decrease tissue perfusion. A vasodilating agent to lower the systemic vascular resistance would lead to profound hypotension and possibly complete vascular collapse because of pooling of an already depleted vascular volume. To properly treat this patient, rapid fluid infusion and expansion of the intravascular volume must be undertaken. Therapy must be directed at increasing cardiac output without creating too high a myocardial O2 demand on the already failing heart. Administration of nitroglycerin could be expected to reduce both preload and afterload, but, if given without an inotrope, it would create unacceptable hypotension. Nitroprusside similarly would achieve afterload reduction but would result in hypotension if not accompanied by an inotropic agent. A -blocker would act deleteriously by reducing cardiac contractility and slowing the heart rate in a setting in which cardiac output is likely to be rate-dependent. Dobutamine is a synthetic catecholamine that is becoming the inotropic agent of choice in cardiogenic shock. As a 1-adrenergic agonist, it improves cardiac performance in pump failure both by positive inotropy and peripheral vasodilation. With minimal chronotropic effect, dobutamine only marginally increases myocardial O2 demand. Local action on -opiate receptors ensures pain relief and consequent improvement in respiration without vasodilation or paralysis. Their slow absorption into the circulation also ensures a low incidence of centrally mediated side effects, such as respiratory depression or generalized itching. When these do occur, the intravenous injection of an opiate antagonist is an effective antidote. One poorly understood side effect, which is apparently unrelated to systemic levels, is a profound reduction in gastric activity. This may be an important consideration after thoracic surgery when an early resumption of oral intake is anticipated. An increased heart rate will directly increase the cardiac output and cardiac index. The remaining choices will either decrease or not affect the stroke volume and consequently will not increase the cardiac index. The causes are obscure but probably lead to a common final pathway of gallbladder ischemia. The diagnosis is often extremely difficult because the signs and symptoms may be those of occult sepsis. Moreover, the patients are often intubated, sedated, or confused as a consequence of the other therapeutic or medical factors. Biochemical tests, though frequently revealing abnormal liver function, are nonspecific and nondiagnostic. Percutaneous drainage of the gallbladder is usually curative of acalculous cholecystitis and affords stabilizing palliation if calculous cholecystitis is present. Antibiotics without drainage are too cautious a choice for a patient with a potentially fatal complication. In the early phase of septic shock, the respiratory profile is characterized by mild hypoxia with a compensatory hyperventilation and respiratory alkalosis. Hemodynamically, a hyperdynamic state is seen with an increase in cardiac output and a decrease in peripheral vascular resistance in the face of relatively normal central pressures. This includes fluid replacement and vasopressors as well as antibiotic therapy aimed particularly at gram-negative rods and anaerobes for patients with presumed intra-abdominal collections, especially after bowel surgery. Laparotomy and drainage of a collection is the definitive therapy but should await stabilization of the patient and confirmation of the presence and location of such a collection. Also, the patient may have pulsus paradoxus, which is manifested by a decrease in systolic blood pressure by more than 10 mm Hg at the end of the inspiratory phase of respiration. On Swan-Ganz monitoring, there will be equalization of pressures across the four chambers.

A newborn infant born from a mother with polyhydramnios presents with excessive salivation along with coughing and choking with the first oral feeding skin care natural tips decadron 1mg low price. An x-ray of the abdomen shows gas in stomach and a nasogastric tube coiled in the esophagus skin care with peptides generic decadron 8mg mastercard. Upon examination there are abdominal contents (small bowel and liver) protruding directly through the umbilical ring. A Silastic silo should be placed with immediate reduction of the viscera into the abdominal cavity. Enteral feeds for nutritional support should be initiated early prior to operative management. A 29-week-old previously healthy male infant presents with fevers, abdominal distention, feeding intolerance, and bloody stools at 3 weeks of age. The patient undergoes x-ray and ultrasound examination for possible necrotizing enterocolitis. Which of the following findings on imaging is an indication for surgical management Abdominal x-rays reveal dilated loops of small bowel, absence of air-fluid levels, and a mass of meconium within the right side of the abdomen mixed with gas to give a ground-glass appearance. Which of the following should be performed as the initial management of the patient Bowel rest with nasogastric tube decompression and broad-spectrum intravenous antibiotics c. Ultrasound of the abdomen reveals a pyloric muscle thickness of 8 mm (normal 3-4 mm). Fluid hydration and correction of electrolyte abnormalities prior to operative management. Administration of sodium bicarbonate to correct aciduria prior to operative management 505. A full-term male newborn experiences respiratory distress immediately after birth. A 2-year-old asymptomatic child is noted to have a systolic murmur, hypertension, and diminished femoral pulses. Transposition of the great vessels Questions 509 and 510 For each patient, select the most likely congenital cardiac anomaly. A noncyanotic 2-day-old child has a systolic murmur along the left sternal border; examination is otherwise normal. Imperforate anus is a type of anorectal malformation that affects males and females with approximately the same frequency, occurring in 1 in 5000 live births. Anorectal malformations can be associated with other anomalies such as esophageal atresia or a tethered spinal cord which explains why a complete workup for associated lesions is important. The management of imperforate anus is dependent on whether the lesion is high or low, which is defined by the location of the end of the rectum relative to the level of the levator ani complex. The rectal fistula may end in the prostatic urethra or vagina in the high cases, while the low cases terminate in a perineal fistula. In females, high imperforate anus often occurs with a persistent cloaca (where the rectum, vagina, and urethra share a single perineal orifice). For the low cases, only a perineal operation may be required, and these children will be expected to be continent. A 2-stage procedure-diverting colostomy followed by a subsequent pull-through procedure such as a posterior sagittal anoplasty-will be required for the high imperforate anus, and the likelihood of continence is smaller. If there is doubt about the level or location of the termination of the rectum, it is better to perform a temporary colostomy than to risk future incontinence. The biopsy should be taken at least 2 cm above the dentate line since the finding of aganglionosis at the level of the internal sphincter may be normal. Findings on barium enema-a distal narrow segment of bowel with markedly distended colon proximally (possibly with a transition zone) or lack of elimination of contrast after 24 hours-are suggestive of Hirschsprung disease. Symptoms may go unrecognized in the newborn period, with consequent development of malnutrition or enterocolitis. Definitive repair is best delayed until nutritional status is adequate and the chronically distended bowel has returned to normal size. Unlike the situation with imperforate anus, which is associated with a high incidence of genitourinary tract anomalies and risk of long-term fecal incontinence, in Hirschsprung disease repair leads to satisfactory bowel function in most affected patients. Omphalocele and gastroschisis result in evisceration of bowel and require emergency surgical treatment to effect immediate or staged reduction and abdominal wall closure.
