Randomized Controlled Trial Clinical TrialInteraction of vecuronium with piperacillin or cefoxitin evaluated in a prospective, randomized, double-blind clinical trial.
Interactions between beta-lactam antibiotics, particularly acylaminopenicillins, and vecuronium, a widely used muscle relaxant, leading to prolonged neuromuscular blockade have been reported in studies of experimental animals and in a few clinical case reports. In the clinical reports, however, confounding factors always existed. A clinical trial to evaluate interactions between vecuronium and cefoxitin or piperacillin was conducted. ⋯ Cefoxitin and piperacillin administered pre- or intra-operatively are not associated with clinically important prolongation of muscle relaxation induced by vecuronium. The potential for prolongation of neuromuscular blockade induced by vecuronium through concomitant administration of piperacillin or cefoxitin as antibiotic prophylaxis was investigated in a clinical trial of 30 patients having major abdominal operations. Quantitative measurement of neuromuscular blockade was done using the electromyographic twitch response to a supramaximal current stimulus.

Comparative StudyPenetrating cardiac wounds: predictive value of trauma indices and the necessity of terminology standardization.
The authors evaluated the usefulness of different trauma indices in the prediction of outcome following penetrating cardiac wounds. Sixty-three patients were retrospectively reviewed. Age, mechanism of injury, Physiologic Index (PI) on admission, site of injury, associated injuries, ISS, RTS, Penetrating Cardiac Trauma Index (PCTI), Penetrating Thoracic Trauma Index (PTTI), Penetrating Trauma Index (PTI), TRISS and mortality rate were reviewed. ⋯ We conclude that physiologic impairment, shock, and GSW are variables with high significance on mortality. Trauma indices such as PI, RTS, PCTI, PTTI, PTI, and ISS are good predictors of outcome. Trauma indices are an important tool to objectively compare results among different institutions.

Comparative StudyDoes oxygen delivery-directed resuscitation worsen outcome of head injured patients with multisystem injuries?
There is concern that oxygen delivery-directed resuscitation in patients with multiple trauma, including severe head injury, may worsen neurologic recovery. To study this, we retrospectively examined 31 patients admitted over an 18-month period who met the inclusion criteria of having suffered blunt trauma, were between 15 and 65 years of age, had an admission Glasgow coma scale of < or = 8, intact corneal and gag reflexes, and extracranial injury with an Abbreviated Injury score of > or = 3. All patients were placed on intracranial pressure monitors. In comparing the 14 patients whose resuscitation was guided by oxygen delivery (DO2) with the 17 who were resuscitated by standard fluid restriction (FR), we found that despite the DO2 group's having received a significantly greater volume of resuscitation fluids in the first 48 hours after injury, there was no difference in the neurologic recovery between the two groups.

Application of field triage guidelines by pre-hospital personnel: is mechanism of injury a valid guideline for patient triage?
We prospectively investigated the appropriateness of Mechanism of Injury as an exclusive indicator for trauma center triage. For all patients transported to our level 1 trauma center, EMS personnel identified applicable American College of Surgeons' Committee on Trauma field triage guidelines. A total of 112 questionnaires were completed. ⋯ Fourteen (16.9%) had ISS scores > 15. Defining an ISS of 16 or greater as severe injury, mechanism of injury alone had a positive predictive value of only 6.9%. Mechanism of injury may not, by itself, justify bypass of local hospitals in favor of trauma centers.

The use of antibiotics for patients undergoing tube thoracostomy was determined to be highly variable based on a study conducted at a national meeting of surgeons. A meta-analysis of six randomized studies previously reported was performed. The analysis was carried out using the Confidence Profile Method software FAST*PRO. ⋯ The results of this meta-analysis suggest that antibiotics should be used in patients undergoing tube thoracostomy. Antibiotic selection should maximize therapy for Staph. aureus. The implementation of this practice guideline will require the co-operation of multiple specialty oriented physicians and surgeons.
