Administration of amphotericin B in lipid emulsion decreases nephrotoxicity: results of a prospective, randomized, controlled study in critically ill patients.

OBJECTIVES: To evaluate the differences in efficacy and in clinical and biochemical tolerance to amphotericin B administered in a lipid emulsion compared with amphotericin B administered in 5% dextrose in water in the treatment of Candida albicans infection in intensive care unit (ICU) patients. DESIGN: Prospective, controlled, randomized study, conducted during a 2.5-yr period, comparing the two treatment protocols. SETTING: General ICU of a university-affiliated municipal hospital. PATIENTS: Sixty consecutive critically ill patients with confirmed or suspected Candida infection. INTERVENTIONS: Patients received amphotericin B (1 mg/kg/24 hrs), administered randomly in 5% dextrose in water (group A), or in lipid emulsion (20% intralipid) (group B). MEASUREMENTS AND MAIN RESULTS: Clinical tolerance (fever, chills, hemodynamics), hepatorenal tolerance, and biological tolerance (serum electrolytes and coagulation profile) were evaluated. Patients receiving amphotericin B in lipid emulsion experienced a lower frequency rate of drug-associated fever (61.4% vs. 5.8%, p < .003) rigors (54% vs. 8.5%, p < .004), hypotension (17% vs. 0%), and nephrotoxicity (increase of serum creatinine concentration 66.7% vs. 20%, p < .0002). Significant (264,500 +/- 71,460 to 163,570 +/- 34,450 mm3, p < .01) thrombocytopenia, not associated with active bleeding, occurred in patients receiving amphotericin B lipid in emulsion but not in patients receiving the drug in dextrose. CONCLUSIONS: Treatment with amphotericin B in a lipid emulsion when given to critically ill patients with Candida sepsis seems to be safer and as effective as the conventional mode of administration.

Disruption of cholecystoenteric fistula induced by minor blunt trauma.

Biliary enteric fistulas are a rare occurrence in general surgeon practice. We describe a patient who sustained a minor blunt abdominal trauma. In this case, periduodenal fluid resulted in exploratory laparotomy. At exploration, disruption of double cholecystoenteric fistula was revealed.

Blunt injury of the small intestine and mesentery--the trauma surgeon's Achilles heel?

Eighteen patients with small intestine or mesenteric injury following blunt abdominal trauma were operated over a 34-month period. Early diagnosis and surgery, less than 6 hours after admission, was achieved in 10 patients (56%), seven of whom had haemorrhagic shock and had positive diagnostic peritoneal lavage or ultrasonography on admission. Three haemodynamically stable patients had a diagnostic abdominal computed tomography. Diagnosis was delayed in eight patients (44%) resulting in a gap between admission and surgery that varied from 20 hours to 46 days. The delay was related to lack of suspicion of injuries in haemodynamically stable patients despite a seat-belt sign, or false negative abdominal computed tomography. Diagnosis was delayed in six of seven patients (86%) where the only injury on admission was an isolated intestinal or mesenteric injury. In 11 patients there were associated abdominal or other system injuries. Late diagnosis was associated with an increased morbidity and longer hospital stay, relating to intestinal and mesenteric injury. In conclusion, a seat belt sign is highly suspicious of intestinal or mesenteric injury. Computed tomography was unreliable in diagnosing blunt intestinal and mesenteric injuries, and if equivocal, should be followed by diagnostic peritoneal lavage if nonoperative management is selected. Delayed diagnosis is often related to isolation of intestinal and mesenteric injury and results in increased morbidity and hospital stay. Every attempt should be made to reach a diagnosis within six hours of admission to the trauma unit. A management algorithm is proposed.

Early tracheostomy in trauma patients.

A retrospective analysis of 118 trauma patients who underwent tracheostomy for airway and pulmonary management was undertaken. Timing of the procedure was defined as early (0-3 days), intermediate (4-7 days), and late (> 7 days). Head injury patients received tracheostomy early (p < 0.00003). Aspiration evaluated by modified bedside aspiration test was a frequent occurrence in all three groups with no difference in incidence (p < 0.34). Pneumonia was less frequent in the early group compared with the intermediate and late groups (p < 0.0034). The incidence of pneumonia in the early group was not different from that observed in early extubated patients (n = 282; p < 0.23). Our study suggests that early tracheostomy may decrease pulmonary septic complications in trauma patients. Although no change in length of stay can be attributed to the early performance of tracheostomy, preventing pneumonia in the intensive care unit setting with its resulting high expense is beneficial.

Heparin-induced thrombocytopenia and fatal thrombosis in a patient with activated protein C resistance.

We report a 20-year-old woman who developed heparin-induced thrombocytopenia (HIT) associated with devastating and fatal multiorgan thrombosis. The patient, her mother, and her brother were found to have resistance to activated protein C (APC), and the congenital thrombophilia in this family was verified by the finding of the Arg506 Gln mutation in factor V. This is the first case of HIT and APC resistance. The consequences of this association are discussed.

Blunt vascular injury associated with closed mid-shaft femur fracture: a plea for concern.

During a period of six years, 765 consecutive patients were treated by the trauma service at Allegheny General Hospital for closed mid-shaft femur fractures that were a component of their injury complex. Thirty-one patients underwent angiography of the involved extremity for indications including loss of pulses in eleven and large hematomas or deformities of the thigh in the remainder. Ten patients (1.3%) were found to have acute vascular injuries. In nine patients there was an intimal flap of the superficial femoral artery (SFA), and in one, a pseudoaneurysm. Two patients had injuries of the femoral nerve. Three patients had no other associated major injuries (Injury Severity Score range, 10-19). Twelve months after the initial injury, one patient developed an arteriovenous fistula of the SFA. Detailed, repeated physical examinations, early utilization of angiography, and intensive follow-up by the trauma surgeon or orthopedic surgeon of patients with closed mid-shaft femur fractures should lead to early recognition of this potentially serious association.

Enhanced rim around infarcted, traumatized spleen on computed tomographic scans: case report.

Computed tomography is considered a reliable imaging technique when determining the extent of splenic injury. We present the case of a patient with a traumatic infarct of the spleen detected by computed tomographic scanning of the abdomen. During laparotomy there was an infarction of the spleen from a hilar injury in addition to bleeding from the splenic vein. We conclude that ongoing bleeding from the splenic hilar vessel can lead to a rim of enhancement around the spleen from contrast material. This should be taken into account when a decision is made for nonsurgical management.

Diving injuries: a preventable catastrophe.

During a 5-year period from January 1987 through January 1992, 58 patients were admitted to the Allegheny General Hospital trauma center for non-scuba, non-suicidal diving injuries. There were 46 men and 12 women (mean age, 23 years). Forty-five patients were injured in swimming pools. Twenty-two patients had blood alcohol levels > 100 mg/dL. Cervical spine injury was the most common pathologic entity encountered in this group of patients. Closed head injury, pelvic fracture, thoracic vertebral fracture, and rib fractures were other injuries identified. Some patients had multiple organ failure syndrome. Aquatic recreational activities carry a risk for injury that is preventable. The mechanism, clinical data, and complications of 58 patients are presented and the importance of prevention is discussed.

Delayed rupture of the spleen--myths, facts, and their importance: case reports and literature review.

Over a 1-year period, three patients were seen in our trauma service with delayed bleeding (> or = 7 days) from an initially inapparent splenic injury. This entity was defined as a late occurrence of signs and symptoms attributed to splenic injury not detected by diagnostic computed tomographic (CT) scanning during the initial examination. We believe that this represents an "injury in evolution" minor enough to go undetected on initial CT scans of the abdomen. A high index of suspicion and liberal utilization of imaging techniques are essential for the identification of delayed splenic rupture. Further multicenter studies are required to delineate the true incidence of its occurrence and its clinical significance. We conclude that "delayed rupture" of the spleen is a true clinical entity. The occurrence of a delayed rupture may prove hazardous to patients discharged early from the hospital after blunt abdominal injury. A classification system to assess this type of injury is suggested.
