In October 2000, our institution implemented a clinical practice guideline (CPG) utilizing selective computed tomography (CT) and ultrasound scan (US) for the evaluation of children with suspected appendicitis. The authors sought to determine surgical outcomes and diagnostic accuracy in the CPG period. ⋯ A clinical practice guideline selectively utilizing CT and US is highly accurate in the diagnosis of acute appendicitis, minimizing the need for inpatient admission for serial examinations.

Most children and adults with blunt splenic injuries are treated nonoperatively by well-established management protocols. The "blush sign" is an active pooling of contrast material within or around the spleen seen during intravenous enhanced computed tomography (CT) scan. Adult treatment algorithms often include the "blush sign" as an indication for embolization or surgical intervention. This study was designed to evaluate the implications of the "blush sign" in children with blunt splenic injuries. ⋯ Although associated with higher grades of injury, the blush sign did not mandate embolization or surgical intervention in children with blunt splenic trauma in this series. Severe splenic injuries with a blush sign on the initial CT scan may be successfully treated nonoperatively when using an established treatment protocol. Management should be based primarily on physiological response to injury rather than the radiologic features of the injury.

Minor surgical procedures in children, while usually not requiring general anesthesia, need effective control of pain, anxiety, and motion. Certain techniques of conscious sedation may result in loss of protective airway reflexes. Nitrous oxide, however, when inhaled at levels below 50% maintains protective reflexes and does not require fasting or postprocedure monitoring. This study prospectively examines the efficacy of nitrous oxide analgesia in children undergoing outpatient surgical procedures. ⋯ Nitrous oxide analgesia is a cost-effective and efficacious alternative to conscious sedation or general anesthesia for minor pediatric surgical procedures. In the office or outpatient setting, the technique provides for almost pain/anxiety-free surgery, no postoperative monitoring, and a high degree of satisfaction for patients, parents, and staff.

The management of the contralateral region in a child with a known inguinal hernia has been debated by surgeons for more than 50 years. However, the perspective of the child's parents has not been sought, and this study was designed to evaluate parental views on this topic. ⋯ When presented options regarding management of a unilateral inguinal hernia, parents preferred laparoscopic inspection and repair of the contralateral region, if needed, more for convenience than for concerns about a second procedure and anesthesia.

Comparative Study
Heart energy metabolism after intestinal ischaemia and reperfusion.
Multiple organ failure subsequent to intestinal ischaemia and reperfusion (I/R) includes cardiac failure, but little is known about heart energy metabolism in this setting. This study investigates the effects of intestinal I/R on heart energy metabolism and evaluates the effects of moderate hypothermia. ⋯ These results suggest that although cardiac ATP supply was maintained during intestinal I/R at normothermia, the balance of substrate utilisation was shifted from fatty acid oxidation to carbohydrate utilisation. However, moderate hypothermia modified these changes. The beneficial effect of moderate hypothermia on cardiac metabolism during intestinal I/R has potential clinical application in various surgical conditions.
