The ability of physicians to identify a patent processus vaginalis by laparoscopic examination of the internal ring is now well established, but the efficacy on patient outcome is not. The authors reviewed their experience to determine the effect of diagnostic laparoscopy of the internal ring on the management of children with inguinal hernias. The records(More)
In 38 boys with clinical unilateral inguinal hernias (CUIH), the contralateral processus vaginalis was examined laparoscopically before surgical manipulation at the time of elective inguinal herniorrhaphy. General anesthesia was used in each case, and a 30 degrees, 2.7-mm laparoscopic was introduced using standard techniques. Positive laparoscope findings(More)
We used peritoneal infusions of 2.5% dextrose solution as an adjunct to resuscitation of 2 very low-birth-weight infants having perforated necrotizing enterocolitis. This was repeated every 12 hours for 7 days before and 1 day after extensive bowel resection. The designation of this research method has been termed direct peritoneal resuscitation. We discuss(More)
BACKGROUND Effective nonelastic strap-based tourniquets are typically pulled tight and friction or hook-and-loop secured before engaging a mechanical advantage system to reach arterial occlusion pressure. This study examined the effects of skin surface initial secured pressure (Friction Pressure) on the skin surface pressure applied at arterial occlusion(More)
BACKGROUND Pulse oximeters are common and include arterial pulse detection as part of their methodology. The authors investigated the possible usefulness of pulse oximeters for monitoring extremity tourniquet arterial occlusion. METHODS Tactical Ratcheting Medical Tourniquets were tightened to the least Doppler-determined occluding pressure at mid-thigh(More)
BACKGROUND Pressure decreases occur after tourniquet application, risking arterial occlusion loss. Our hypothesis was that the decreases could be mathematically described, allowing creation of evidence-based, tourniquet-reassessment- time recommendations. METHODS Four tourniquets with width (3.8cm, 3.8cm, 13.7cm, 10.4cm), elasticity (none, none, mixed(More)
