Randomized Controlled Trial Clinical TrialRole of prophylactic antibiotics for tube thoracostomy in chest trauma.
The objective of this study was to evaluate the efficacy of antibiotic prophylaxis in association with tube thoracostomy for chest trauma patients with Injury Severity Scores of 9 or 10. A double-blind randomized clinical trial of patients requiring tube thoracostomy was performed at an urban Level 1 trauma center. All patients included in this series were patients with Injury Severity Scores of 9 or 10 (hemothorax/pneumothorax) who suffered isolated chest trauma secondary to blunt or penetrating trauma. ⋯ In the 71 patients receiving antibiotic, 7 complications (1 pleural effusion, 2 chest tube reinsertions, 4 additional chest tubes) occurred, none of which were infectious. In the 68 patients receiving placebo, 7 complications (2 empyemas, 2 pneumonias with effusions, 1 pleural effusion, 2 chest tube reinsertions) occurred, 4 of which were infectious and required antibiotic intervention (P = 0.05, Fisher's exact test). This study showed that patients receiving antibiotics have a significantly reduced incidence of infectious complications and suggests that patients who undergo tube thoracostomy for chest trauma would benefit from administration of prophylactic antibiotics.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialImpact an anatomical site on bacteriological and clinical outcome in the management of intra-abdominal infections.
The clinical and bacteriological results of treatment for 429 patients who had intra-abdominal infection were analyzed to determine whether the anatomical origin of peritonitis influenced outcome. All patients had received effective broad spectrum antimicrobial therapy and operation in four multicenter trials. The diagnoses of infection were categorized into three sites: upper gastrointestinal tract, complicated appendicitis, and lower gastrointestinal tract. ⋯ Mortality was related to recurrent intra-abdominal infection after an unsuccessful primary operation and a serum albumin less than 25 g/l. Clinical trails of antimicrobials for intra-abdominal infection should consider stratification of patients according to these three levels of alimentary tract perforation when the site is known preoperatively. Patients who have infection secondary to previous surgery or who are malnourished represent a higher risk group even with appropriate antibiotics.

Randomized Controlled Trial Clinical TrialThe effects of epidural anesthesia on the neuroendocrine response to major surgical stress: a randomized prospective trial.
It has long been held that the acute-phase and neuroendocrine response to stress requires afferent neural input for its propagation. To further clarify the role of afferent neural impulses in this process and to determine the ability of epidural anesthesia to attenuate the normal perioperative stress response, 39 patients undergoing uncomplicated abdominal aortic replacement were randomized to receive either general anesthesia with postoperative patient-controlled intravenous morphine (n = 19) or combined regional/general anesthesia with intraoperative epidural catheter anesthesia using Bupivacaine to the T4 dermatome level followed by postoperative epidural morphine (n = 20). The stress response was quantitated by blinded measurement of baseline and postoperative (0, 12, 24, 48, and 72 hours) serum cortisol, epinephrine norepinephrine, total catecholamines, interleukin (IL)-1beta, IL-6, tumor necrosis factor (TNF)-alpha, and C-reactive protein (CRP). ⋯ Those patients with operative times greater than 5 hours (n = 10) developed significantly higher CRP, IL-1beta, IL-6, and TNF-alpha levels (P < 0.05) at 12 and 24 hours postoperatively than those with total operative times less than 4 hours (n = 16). The neuroendocrine response to major surgical stress is propagated normally despite epidural blockade and is intensified with prolonged operative times. The inflammatory cytokines appear to play a major role in this process.

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.

Randomized Controlled Trial Comparative Study Clinical TrialFailure of antiseptic bonding to prevent central venous catheter-related infection and sepsis.
Infection associated with the use of triple lumen catheters in hospitals is a frequent and serious complication. The prevailing hypothesis for the origin of catheter-related infection (CRI) is bacterial colonization and subsequent infection of the skin insertion site and catheter interface. The recently released ARROWgard catheter contains a bonded synergistic combination of silver sulfadiazine and chlorhexidine, which is thought to render the catheter resistant to bacterial colonization and subsequent sepsis. ⋯ The rate of CRI for the ARROWgard was 10.9 per cent, compared with 12.9 per cent for the standard catheter (P = NS). The rate of CRS for the ARROWgard was 8.7 per cent, compared with 8.1 per cent for the standard catheter (P = NS). The coating of central venous catheters with silver sulfadiazine and chlorhexidine does not reduce the rate CRI or CRS when compared with standard central venous catheters in patients receiving TPN.
