Induced hypotension.

Abstract

The use of induced hypotension in the hands of a competent anaesthetist combined with the careful technique of a surgeon skilled in operating under these conditions can aid surgical access, improve delineation of pathology, and reduce levels of blood loss, all of which are to the advantage of the patient. These advantages should encourage surgical and anaesthetic teams to become accomplished exponents of the art.

Hyperkalemic periodic paralysis episode during halothane anesthesia in a horse.

A 7-month-old Quarter Horse filly was admitted for surgical repair of a right olecranon fracture. Anesthesia was achieved with xylazine hydrochloride, guaifenesin, ketamine hydrochloride, and halothane. Two and a half hours after induction of anesthesia, myotonia, muscle fasciculations, and sweating, concurrent with high serum potassium concentration and associated electrocardiographic changes consistent with hyperkalemic periodic paralysis, were observed. Treatment included intermittent positive-pressure ventilation, changing intravenous administration of fluids from lactated Ringer's solution to 0.9% NaCl solution, and administration of calcium gluconate, glycopyrrolate, dopamine, and sodium bicarbonate. Clinical signs resolved with the return of serum potassium concentrations to the reference range. The horse was confirmed to be heterozygous for hyperkalemic periodic paralysis by DNA testing.

[Preoperative risk assessment of children with Duchenne muscular dystrophy and relevance for anesthesia and intra- and postoperative course].

BACKGROUND: Patients suffering from muscle disorders have an elevated anesthetic risk, i.e. to develop malignant hyperthermia or rhabdomyolysis. In addition serious cardial and pulmonal complications are imminent during anesthesia for surgery. PATIENTS AND METHODS: We investigated retrospectively the preoperative risk factors of 81 Duchenne patients undergoing 101 anesthesia (79 for muscle releasement operations and 23 for spine surgery) and the relation to possible complications due to the anesthesia and the intra- and postoperative course. RESULTS AND DISCUSSION: 83% of the patients showed pathologic ECG, 26% cardiac insufficiency in echocardiography, 31% pathologic X-rays of the thorax and 73% serious pulmonary restriction. Consequently avoiding of anesthetic agents with a high trigger potential for developing malignant hyperthermia (i.e. halothane or muscle relaxants type succinylcholine) prevented severest complications as malignant hyperthermia, rhabdomyolysis or cardiac arrest. Nevertheless other complications (i.e. arrhythmia, cardiac insufficiency) occurred due to the cardiac and pulmonary limitations more pronounced in the older patients of the spine surgery group.
