Preoperative hair removal: a random prospective study of shaving versus clipping.

We report the results of a random, prospective study of electrical clipping versus routine razor shaving in the removal of hair immediately before operation. Two hundred patients having elective inguinal herniorrhaphy according to strict protocol were included in this study. Unsatisfactory skin preparation, as evidenced by gross cuts made in the skin during hair removal, was noted in 7% of those shaved and 4% of those clipped. Two subcutaneous wound infections occurred in the shaved group (2%) and one in the clipped group (1%). This study indicates that preoperative clipping of hair with electric barber's clippers immediately before operation is a safe, well tolerated procedure that does not increase the risk of postoperative wound infection.

The use of stroma-free hemoglobin solution for partial exchange transfusion in aortic resection in dogs.

Vascular surgery involves multiple transfusions with their concomitant hazards. At the start of each vascular procedure, 20 per cent of each patient's blood (approximately 1,000 of 5,600 ml) is removed and replaced with colloid and crystalloid and the withdrawn blood returned at the end of surgery. Theoretically, if 40 per cent of the blood volume (2,000+ ml) could be withdrawn, essentially no banked blood would be required for a major vascular procedure. Therefore, 40 per cent (900+ ml) of the blood volume of twenty greyhounds was withdrawn under anesthesia and replaced with stroma-free hemoglobin solution (SFHS). Abdominal aortic resection and graft replacement was performed, and any blood lost during the procedure was replaced with SFHS. After surgery the withdrawn blood was returned to the dog and excess volume removed with postoperative hemodilution diuresis. The study included a battery of twenty tests for monitoring during the procedure and at intervals from this project that in greyhounds 40 per cent or more of the blood volume may be removed and replaced with SFHS and major vascular surgery done without undue risk and with unaltered kidney function.

New Doppler pressure indexes plotted as curves. Curve configuration used to determine sites of arterial obstruction.

Brachial, femoral (in the groin), popliteal, and tibial systolic blood pressures were determined with the Doppler technic. New indexes were developed: femoral/brachial (B/B), popliteal/femoral (P/F), ankle/femoral (A/F), and ankle/popliteal (A/P). Curves were plotted using these indexes and compared with established configurations. As a result the site or sites of obstruction were rapidly determined.
