Randomized Controlled Trial Clinical TrialEffect of intramuscular intraoperative pain medication on narcotic usage after laparoscopic cholecystectomy.
The purpose of this randomized, double-blind, clinical trial was to determine whether intraoperative, intramuscular (IM) injections of meperidine or ketorolac would improve postoperative pain relief in patients undergoing elective laparoscopic cholecystectomy. A total of 125 patients were entered into five study groups: 1) (N = 23) control placebo; 2) (N = 31) meperidine 100 mg IM intraoperative preprocedure; 3) (N = 20) meperidine 100 mg IM intraoperative postprocedure; 4) (N = 25) ketorolac tromethamine 60 mg IM intraoperative preprocedure; 5) (N = 26) ketorolac tromethamine 60 mg IM postprocedure. All groups were analyzed by comparing the amount of pain medication received in the recovery room, the time until first oral pain medication was requested, the overall amount of pain medication used in the first 24 hours, the percent requiring IM medication, and the pain score ratings from each group. ⋯ Both Groups 4 and 5 had decreased postoperative narcotic usage. Finally, the analogue pain scores showed that both ketorolac groups had significantly less postoperative pain compared to control, whereas the meperidine groups showed no improvement in postoperative pain relief. Intraoperative ketorolac given preprocedure or postprocedure significantly improved postoperative pain management and facilitated the transition to oral pain medication.

Review Case ReportsIntussusception in an adult secondary to an inverted Meckel's diverticulum.
Intussusception secondary to an inverted Meckel's diverticulum is considered to be a rare occurrence. The pathophysiology of the disease process results in a complicated clinical picture of chronic abdominal pain, lower gastrointestinal bleeding, and recurrent obstructive symptoms that may lead to an unnecessary delay in diagnosis. ⋯ The methods of diagnosis and the salient concepts in the surgical management of intussusception are discussed. Special features regarding the pathophysiology and treatment of an inverted Meckel's diverticulum acting as an intussusception are also reviewed.

Pulmonary contusion is the most common injury identified in blunt chest trauma. Despite improvements in diagnostic imaging and critical care, the associated mortality has not appreciably changed over the last three decades. Parenchymal injury ultimately manifests as alveolar collapse and lung consolidation. ⋯ Avoiding fluid overload, oxygen therapy, and a low threshold for mechanical ventilation are useful therapeutic guidelines. Complications include pneumonia and adult respiratory distress syndrome, which may occur in up to one half of all cases. Pulmonary contusion is a serious injury that may complicate patient management as well as pose a vital threat.

A total of 325 patients, aged 80 to 92 (mean 82), underwent cardiac operations with cardiopulmonary bypass over a 4-year period (1991-1995). Hypothermia (22 degrees C) and hyperkalemic cardioplegia were used in each. Coronary bypass procedures only (Group I) were performed in 255 patients with 22 early deaths (8.6%), and the average number of grafts was 3.7 per patient. ⋯ Two hundred seventy-two of the 299 operative survivors were followed for a mean of 18 (range, 3-52) months. The actuarial survival of octogenarians is 92 per cent, 80 per cent, and 65 per cent at 1, 3, and 5 years, respectively, and of the patients surviving operation it was 85 per cent, 70 per cent, and 55 per cent at 1, 3, and 5 years, respectively. At postoperative follow up, 80 per cent of the survivors reported an active functional status, and there was a low incidence of cardiac-related deaths.

Limited value of routine followup CT scans in nonoperative management of blunt liver and splenic injuries.
The objective was to determine the utility of a second CT scan in nonoperative management of blunt liver and splenic trauma. The design was a retrospective review of consecutive cases over a 2-year period in two trauma centers. Subjects were 152 patients with blunt abdominal trauma and isolated injuries to liver and/or spleen. ⋯ Second CT scans were used in 26 patients (26%), one of whom received laparotomy for drainage of a bile leak and three for ongoing bleeding. None of the followup scans showed major progression of injury, and scan findings did not influence decisions for operation in any patients. Routine followup CT scanning is not a justifiable component of nonoperative management protocols for blunt liver and splenic injuries.
