Update on anesthesia management for infants and children.

This review aims at providing the pediatric surgeon with an update on the most important issues in pediatric anesthesia and the changes that have taken place over the last few years. Many practices, entrenched in tradition, are being modified in the light of research that has provided new knowledge, drugs, and techniques. Pediatric anesthesia requires dedication, a sense of anticipation, meticulous attention to detail, and an individual who derives enormous satisfaction from the pleasure to be had from dealing with these small patients and their families.

Limb tourniquets and central temperature in anesthetized children.

We have observed an association between the use of tourniquets for limb surgery and a progressive increase in body temperature in pediatric patients. Consequently, we evaluated the effect of leg tourniquet(s) on intraoperative nasopharyngeal temperature in pediatric patients. We measured central temperature in three groups of children anesthetized with halothane and nitrous oxide: those with unilateral tourniquets (n = 15), those with bilateral tourniquets (n = 8), and a control group not requiring tourniquets (n = 24). Intraoperative ambient temperatures were maintained near 23 degrees C, respiratory gases were actively heated and humidified, and skin was warmed using a circulating water blanket set at 38 degrees C. The control patients remained normothermic during anesthesia and surgery. In contrast, central temperature increased 1.0 +/- 0.6 degrees C in 90 min in those with one tourniquet and 1.7 +/- 0.6 degrees C in those with bilateral tourniquets. The tourniquet-induced hyperthermia appeared to result from decreased effective heat loss from distal skin and from constraint of metabolic heat to the central thermal compartment. These data suggest that pediatric patients requiring intraoperative tourniquets should not be aggressively warmed during surgery.

Hyperthermia resulting from tourniquet application in children.

An association between the use of tourniquets for limb surgery and a progressive increase in body temperature was noticed in paediatric patients in our institution. Because malignant hyperthermia is always a concern in these patients, it was decided to investigate this phenomenon. The anaesthetic records of 70 paediatric patients were studied and divided into three groups. Group I (32 patients) had unilateral lower limb procedures and Group II (24 patients) had bilateral lower limb procedures. Group III, the control group, consisted of 14 patients who had undergone superficial body procedures. The data were analysed by oneway analysis of variance (ANOVA), and comparison between groups was made by unpaired t-tests. The study confirmed our clinical impression of the association.

The case for immediate pyeloplasty in the neonate with ureteropelvic junction obstruction.

The 99mtechnetium-diethylenetriaminepentaacetic acid renal scan allows differentiation of ureteropelvic junction obstruction from multicystic kidney in most instances. Although renal function usually will improve at least a little after relief of obstruction, the young infant is privileged and more improvement can be expected than occurs usually in older children. Since an operation is as safe and results of pyeloplasty are as good in the neonate as in older infants or children early correction of ureteropelvic junction obstruction is advocated in otherwise healthy infants as soon as the diagnosis is established.
