Malignant hyperthermia is a rare disease triggered by succinylcholine and the volatile anesthetic agents in genetically predisposed individuals. Recent studies have implicated an abnormality in the calcium release channel of the sarcoplasmic reticulum in skeletal muscle as the likely etiology. Genetic studies have narrowed the search for the chromosomal abnormality to human chromosome 19. Although the mortality from this disorder has dramatically decreased in the past decade due to the discovery of dantrolene, elective diagnosis of the disorder is only now appearing on the horizon.

Optimal perioperative fluid management in pediatric patients entails a knowledge of the effects of preoperative fasting, perioperative third space losses, and hemorrhage on the patient's fluid compartments. We explain which of the various available intravenous fluids should be used to correct various fluid and electrolyte losses that may occur. The authors also review techniques for limiting homologous transfusion requirements and discuss certain complications associated with blood transfusion.

ReviewPreoperative evaluation and preparation of the pediatric patient.
A successful anesthetic is built on the foundation of the preoperative evaluation and preparation, six features of which will be discussed: (1) content and timing of the anesthesiologist's preoperative evaluation; (2) value of preoperative laboratory testing; (3) psychological effects of hospitalization and surgery; (4) approaches to psychological preparation; (5) pharmacological premedication (except for drugs designed to sedate or reduce anxiety, reviewed in the article by Bennie and McNiece); and (6) preoperative feeding schedules.

Many new diagnostic and surgical procedures rely on immobile equipment such as computed tomography or magnetic resonance scanners, biplanar fluoroscopes, or radiotherapy units. To facilitate these procedures in infants and children, anesthesiologists must provide services in a variety of unique environments. This article reviews the anesthetic equipment and techniques that have been adapted to provide anesthesia for children outside the operating room.
