It appears that the patient has continued bleeding in her abdomen as seen by free fluid there and a blood pressure that does not respond to fluids effective zyvox 600 mg virus 90. Controlling the bleeding in the operating room is the best method to decrease the likelihood of hypotensive episodes purchase zyvox with a visa antibiotics and xtc. Mannitol works to decrease cerebral edema by increasing the osmotic gradi ent from brain tissue to the plasma order genuine zyvox antibiotics for acne nausea, thereby drawing the fluid out of the brain tissue trusted zyvox 600mg virus protection for android. However, mannitol also acts as a significant diuretic and can deplete the total intravascular volume. He has a small intraparenchymal bleed, but because of his rapid presentation to the emergency department, this bleed may "blossom" later. His injury is not severe enough at the moment to warrant intubation, ventriculostomy place ment, vasopressors, or surgical decompression. His car struck the highway divider resulting in a vehicle rollover, and he was ejected from the vehicle. His injuries include: brain injury, pulmonary contu sion with multiple rib factures, pelvic facture, grade 2 splenic laceration, and a femur facture. Respira tory rate and respiratory efforts are important to monitor given his pulmonary contusion and chest wall injuries. To learn to prioritize and coordinate the management of patients with multiple injuries including intra-abdominal injuries, blunt chest injuries, orthopedic injuries, and brain injuries. To learn the criteria for the selection of nonoperative management of solid organ intra-abdominal injuries. Considertions The patient is a 48-year-old man who has been in a high-energy mechanism motor vehicle crash. He has undergone radiographic imaging and his identified injuries include a brain injury, thoracic injuries, pelvic fracture, splenic laceration and a femur fracture. He is at risk for deterioration of his mental status secondary to his brain injury or from developing shock due to splenic or pelvic hemorrhage. Additionally, his respiratory status may deteriorate requiring potential intubation to maintain adequate oxygenation and ventilation. These complications should be prevented and/or addressed aggressively in this patient. For example high-speed motor vehicle crash, fall from a roof, and fall from standing all produce diferent injury patterns. Blunt trauma patients are often quite challenging to treat due to the fact that with a severe mechanism multiple organ systems may be involved. Commonly afected organ systems include the central nervous system (skull, brain, and spine), respiratory system (chest wall and lung), solid intra-abdominal organs (liver and spleen), gastrointestinal system (intestines and the mesentery), urologic system (kidneys and bladder), and musculoskeletal system (long bone and pelvis fractures). Central nervous system injuries will include skull fractures and brain inju ries. The main issue with skull fractures is that there is often underlying associ ated brain injury. Brain injuries include cerebral contusions, epidural hematoma, subdural hematoma, and subarachnoid hemorrhage. These injuries are clinically manifested as altered mental status, or depressed level of consciousness as refected in a decreased Glasgow coma scale score. A brain injury or skull fracture mandates neurosurgical consultation, although the majority of these injuries are treated by observation and serial neurological examinations. Respiratory system injuries include rib fractures, pulmonary contusion, pneu mothorax, and hemothorax. Rib fractures contribute to significant morbidity and even mortality particularly in patients over the age of 45. Rib fractures cause sig nificant pain which can lead to splinted respiration and poor inspiratory efort. The sequelae of this may be pneumonia and respiratory failure requiring mechanical ventilatory support, which carries its own set of complications. Pulmonary con tusions are believed to be due to direct impact of pulmonary parenchyma against the chest wall as a result of significant deceleration force. Clinically, they result in decreased oxygenation as there is a physiologic shunt of damaged lung which may not exchange gas efectively while being perfsed. Unfortunately, pulmonary con tusions often worsen post injury as intravenous fluids may sequester within the injured lung parenchyma. Pneumothorax may occur as a result of a bone fragment from a broken rib lacer ating the pulmonary parenchyma, causing air to accumulate in the pleural space. Prompt recognition and treatment with tube thoracostomy is a life-saving procedure in these patients. Hemothorax is the result of bleeding into the pleural space, most often from the thoracic cage. Besides the risk of exsanguination, accumulated blood in the thorax may lead to infection, resulting in an empyema and sepsis. Solid abdominal organ injury (liver and spleen) manifests as hemorrhage during the initial hours or 1 to 2 days following injuries. Intervention in the form of opera tion or angiography/embolization may be necessary to control hemorrhage. Most clinically significant bleeding will be manifested as drop in blood pressure or hemo globin and hematocrit within the first 24 hours following the injury. Patients with severe liver injuries may develop bile leaks; these patients may present with bile peri tonitis. Hollow viscus injury may result in the development of peritonitis if enteric contents irritate the peritoneal cavity. Clinically, the patients will often exhibit a hyperdynamic picture associated with leukocytosis. This will result in a profound infammatory/septic response and requires operation and possible bowel resection for therapy. Mesenteric injuries may result in exsanguinating hemorrhage or bowel ischemia with delayed presentation of peritonitis. Renal injuries from a blunt mechanism may result in parenchymal laceration or in renovascular injuries. In extremely rare circumstances, particularly ifthe renal pelvis is involved, these injuries may result in the development of a urinoma and sepsis which would require drainage either operatively or percutaneously. The forces involved in a high-energy mecha nism in efect cause a "stretch" of the renal artery fom its origin at the aorta. This causes an intimal injury to the renal artery which will lead to renal artery thrombosis and renal ischemia. Unfortunately, success with revascularization of the kidney fol lowing blunt traumatic injury has been dismal. An ischemic kidney may result in the development of persistent hypertension or chronic flank pain requiring nephrectomy.

A dorsal augmentation graft composed of irradi- ated rib cartilage (purple) is layered with crushed cartilage (green) from the nasal septum. A columellar strut and tip graft, also composed of irradiated rib cartilage (purple), improves tip projection and definition. Removal of a Weir-type alar wedge, including nasal sill, and a V-Y advancement produce a more pleasing alar base. Here, care must be taken not to over-reduce the nose, and osteotomies are not warranted. A dorsal augmentation graft, colum- ellar strut, and tip graft are placed, all composed of irradiated rib cartilage (purple). A plumper graft composed of crushed septal cartilage (green) helps to improve a retracted columella. Removal of a Weir-type alar wedge, including nasal sill, and a V-Yadvancement reduce alar flare and base width. A dorsal augmentation graft composed of irradiated rib cartilage (purple) is again layered with crushed cartilage (green) from the nasal septum. A columellar strut and tip graft, also composed of irradiated rib cartilage (purple), again improves tip projection and definition. Removal of a Weir-type alar wedge, including nasal sill, and a V-Y advancement improves horizontally oriented nostrils by reorienting them more vertically. Note the improvement in the profile by combining radix augmentation with crushed septal cartilage (green), dorsal reduction, and increased tip projection with a columellar strut and tip graft (green).

It is important to remember that changes to the nasal Stucker used a columellar strut and septocolumellar stitch to tip will aﬀect the shape of the alar base. It is important to distin- ment, and both shield-type and infralobular tip grafts.

Tip projection usually requires further nostril unless nasal sill is to be removed. This prevents a tear- enhancement with an anteriorly positioned infralobular or drop or “Q“ deformity. A modified Weir incision placed in the alar-facial groove reduces alar flare without disrupting the continuity of the nostril contour. A modified Weir incision is extended to enter the sill, allowing reduction in the horizontal width of the nostril.

Accordingly discount 600mg zyvox otc antibiotic and birth control, if a patient develops symptomatic bradycardia with another beta blocker buy discount zyvox 600mg on-line antibiotics pneumonia, switching to one of these may help discount 600mg zyvox mastercard virus 68 symptoms. Potential side effects of beta blockers include depression order zyvox 600 mg line antibiotics cause fever, insomnia, bizarre dreams, and sexual dysfunction; however, a review of older clinical trials has shown that the risk is small or nonexistent. The resultant vasodilation reduces both peripheral resistance and venous return to the heart. It is not clear whether doxazosin increased cardiovascular risk or chlorthalidone decreased risk. Carvedilol and labetalol are unusual in that they can block alpha receptors as1 well as beta receptors. Blood pressure reduction results from a combination of actions: (1) alpha blockade promotes dilation of arterioles and veins, (2)1 blockade of cardiac beta receptors reduces heart rate and contractility, and (3)1 blockade of beta receptors on juxtaglomerular cells suppresses release of renin. In addition, clonidine can cause severe rebound hypertension if treatment is abruptly discontinued. Additional adverse effects of methyldopa are hemolytic anemia and liver disorders. Because of its capacity for significant side effects, minoxidil is not used routinely for chronic hypertension. Instead, the drug is reserved for patients with severe hypertension that has not responded to safer drugs. B l a c k B o x Wa r n i n g : M i n o x i d i l Minoxidil can promote pericardial effusion that in some cases progresses to cardiac tamponade. In addition, verapamil and diltiazem have direct suppressant effects on the heart. This reaction is greatest with the dihydropyridines and minimal with verapamil and diltiazem. Reflex tachycardia is low with verapamil and diltiazem because of cardiosuppression. Because dihydropyridines do not block cardiac calcium channels, reflex tachycardia with these drugs can be substantial. As a result, the National Heart, Lung, and Blood Institute has recommended that the use of immediate-release nifedipine be discontinued for treatment of hypertensive emergency. In hypertensive diabetic patients with renal damage, these actions slow progression of kidney injury. Principal adverse effects are persistent cough, first-dose hypotension, angioedema, and hyperkalemia (secondary to suppression of aldosterone release). Because of the risk for hyperkalemia, combined use with potassium supplements or potassium- sparing diuretics is generally avoided. Also, in patients with type 2 diabetes mellitus, use of aliskiren has demonstrated an increased incidence of renal impairment, hypotension, and hyperkalemia. Accordingly, until experience with the drug is more extensive, other antihypertensives should be considered first. Both spironolactone and eplerenone promote renal retention of potassium and hence pose a risk for hyperkalemia. Accordingly, they should not be given to patients with existing hyperkalemia and should not be combined with potassium-sparing diuretics or potassium supplements. Spironolactone is discussed in Chapter 35, and eplerenone is discussed in Chapter 36. As shown in the algorithm at this link, lifestyle changes should be instituted first. If needed, another drug may be added (if the initial drug was well tolerated but inadequate) or substituted (if the initial drug was poorly tolerated). However, before another drug is considered, possible reasons for failure of the initial drug should be assessed. Among these are insufficient dosage, poor adherence, excessive salt intake, and the presence of secondary hypertension. If treatment with two drugs is unsuccessful, a third and even fourth may be added. Initial Drug Selection Initial drug selection is determined by the presence or absence of a compelling indication, defined as a comorbid condition for which a specific class of antihypertensive drugs has been shown to improve outcomes. Initial drugs for patients with and without compelling indications are discussed next. For initial therapy in the absence of a compelling indication, a thiazide diuretic is currently recommended for most patients. This preference is based on long-term controlled trials showing conclusively that thiazides can reduce morbidity and mortality in hypertensive patients and are well tolerated and inexpensive too. Accordingly, these drugs should be reserved for special indications and for patients who have not responded to thiazides. Certain other alternatives—centrally acting sympatholytics and direct-acting vasodilators—are associated with a high incidence of adverse effects and hence are not well suited for initial monotherapy. One last alternative—alpha blockers1 —is no longer recommended as first-line therapy. As noted, when the alpha blocker doxazosin was compared with the diuretic chlorthalidone, doxazosin was associated with a much higher incidence of adverse cardiovascular events. Drugs shown to improve outcomes for six comorbid conditions are indicated in Table 39. Management of hypertension in patients with diabetes and renal disease—two specific comorbid conditions—is discussed further under “Individualizing Therapy. Adapted from The seventh report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. When using two or more drugs to treat hypertension, each drug should come from a different class. In contrast, it would be inappropriate to combine two thiazide diuretics or two beta blockers or two vasodilators. Second, when drugs are used in combination, each can be administered in a lower dosage than would be possible if it were used alone. Third, when proper combinations are selected, one agent can offset the adverse effects of another. However, if a vasodilator is combined with a beta blocker, reflex tachycardia will be minimal. Dosing For each drug in the regimen, dosage should be low initially and then gradually increased. As a result, sympathetic reflexes offer less resistance to the hypotensive effects of therapy. Individualizing Therapy Patients With Comorbid Conditions Comorbid conditions complicate treatment. Two conditions that are especially problematic—renal disease and diabetes—are discussed here. Preferred drugs for patients with these and other comorbid conditions are shown in Table 39. Drugs to avoid in patients with specific comorbid conditions are summarized in Table 39.
