Comparative Study
Level of training, wound care practices, and infection rates.
This prospective, nonrandomized descriptive study compares the traumatic wound infection rates in patients based on level of training of emergency department (ED) practitioners. Wounds were evaluated in 1,163 patients. A wound registry data sheet was prospectively completed on all patients sutured in the ED. ⋯ Patient wound infection rates by practitioner level of training were: medical students, 0/60 (0%); all resident physicians, 17/547 (3.1%); physician assistants, 11/305 (3.6%); and attending physicians 14/251 (5.6%), P was not significant. Comparison of junior (medical students and interns) to senior practitioners (all other practitioners) found no difference in infection rates (8/262 [3.1%] v 34/901 [3.8%], P = .58). In conclusion, carefully selected patients sutured by closely supervised medical students and junior residents have infection rates as low as those sutured by more experienced practitioners.

Abdominal pain (AP) is a common presenting complaint in emergency department (ED) patients. A 1972 study reported that unsupervised surgical residents in a university hospital ED were unable to make a specific diagnosis in 41% of 1,000 AP patients. In the intervening time, ED availability of diagnostic technology has increased, and the reference hospital acquired full-time emergency medicine (EM) faculty. ⋯ One 1993 patient with acute cholecystitis was initially misdiagnosed as having UDAP. Advances in technology and EM faculty presence were temporally associated with improved diagnostic accuracy in patients with AP in a university hospital ED. As compared with 20 years ago, fewer patients required hospitalization, more were assigned a specific diagnosis, and there were fewer cases of missed surgical disease.

Despite widespread use of the Trendelenburg position, its autotransfusion effect remains controversial. Additionally, its adverse effect on cerebral circulation is not generally appreciated. The effects of a 10 degrees head-down tilt on central hemodynamics and flow through the internal jugular vein (IJV) were examined in ten healthy volunteers. ⋯ As a result, calculated IJV blood flow was unchanged throughout the period of tilt. Therefore, the mild trendelenburg position produces a transient autotransfusion effect in normovolemic patients. Our data also suggest that the Trendelenburg produces no adverse effect on cerebral circulation in patients with normal cerebral autoregulation.
