Case Reports
Severe hypothermia with cardiac arrest: complete neurologic recovery in a 4-year-old child.
A 4-year-old girl was lost for 17 hours in a snowstorm. Upon discovery, her core temperature was 72 degrees F (22 degrees C). While undergoing endotracheal intubation in the emergency department, she experienced sudden ventricular fibrillation and cardiac arrest. ⋯ Lavage was continued until core temperature reached 34 degrees C, at which time transport to the pediatric intensive care unit was arranged. She was extubated the next day and discharged home, on the fourth hospital day, with apparent complete neurologic recovery. This is the first report of the successful use of rapid high-volume peritoneal lavage for the treatment of accidental severe hypothermia in a pediatric patient.

Comparative Study
Hemodynamic effects of positive end-expiratory pressure during partial liquid ventilation in newborn lambs.
The aim of this study was to compare the effect of positive end-expiratory pressure (PEEP) application on hemodynamics, lung mechanics, and oxygenation in the intact newborn lung during conventional ventilation (CV) and partial liquid ventilation (PLV) at functional residual capacity (FRC). CV or PLV modes of ventilation do not affect hemodynamics nor the optimum PEEP for oxygenation. ⋯ Hemodynamically, CO is impaired at a PEEP above 12 cm H(2)O in intact lungs. PFC at FRC does provide an advantage in lung mechanics more than 10 to 12 cm H(2)O of PEEP by decreasing the amount PIP needed to achieve the similar levels of gas exchange and minute ventilation, implying a reduced risk for barotrauma with chronic ventilation. Thus, selection of the appropriate level of PEEP appears to be important if PLV is to be utilized at FRC. The best strategy for PLV, including the selection of PEEP, remains to be determined.

Comparative Study
Three quantitative approaches to the diagnosis of abdominal pain in children: practical applications of decision theory.
The authors compared 3 quantitative methods for assisting clinicians in the differential diagnosis of abdominal pain in children, where the most common important endpoint is whether the patient has appendicitis. Pretest probability in different age and sex groups were determined to perform Bayesian analysis, binary logistic regression was used to determine which variables were statistically significantly likely to contribute to a diagnosis, and recursive partitioning was used to build decision trees with quantitative endpoints. ⋯ Knowing the pretest probabilities in a specific population allows the physician to evaluate the likely diagnoses first. Other quantitative methods can help judge how much importance a certain criterion should have in the decision making and how much a particular test is likely to influence the probability of a correct diagnosis. It now should be possible to make these sophisticated quantitative methods readily available to clinicians via the computer.
