A 53-year-old woman who had experienced symptoms of fulminant malignant hyperthermia (MH) by sevoflurane a week before and her MH muscle biopsy revealing positive later, underwent the right hemicolectomy under total intravenous anesthesia with propofol and fentanyl. The patient's body temperature
A 7-year-old boy with congenital myotonic dystrophy (MD) and developmental retardation underwent an emergency surgery for strangulation ileus. General anesthesia was maintained using sevoflurane and fentanyl. While intraoperative arterial blood pressure, pulse and rectal temperature remained stable,
The time course of changes in brain electrical activity during halothane anesthesia was examined in 12 malignant hyperthermia-susceptible (MHS) and 14 normal (nMHS) swine. Power densities in selected frequency bands were calculated from the electroen-cephalogram (EEG). EEG and systemic variables
Malignant hyperthermia is a potentially lethal inherited disorder characterized by disturbance of calcium homeostasis in skeletal muscle. Volatile anesthetics and/or the depolarizing muscle relaxant succinylcholine may induce this hypermetabolic muscular syndrome due to uncontrolled sarcoplasmic
Malignant hyperthermia (MH) is a rare hereditary, mostly subclinical myopathy. Trigger substances, such as volatile anesthetic agents and the depolarizing muscle relaxant succinylcholine can induce a potentially fatal metabolic increase in predisposed patients caused by a dysregulation of the
Malignant Hyperthermia (MH) has been a recognized complication of general anesthesia after the first case reports in the 1940's. Since then a great deal has been discovered about the genetics, pathophysiology and treatment of this once fatal syndrome. MH is the only clinical entity specifically
Malignant hyperthermia is now recognized as a distinct entity in anesthetic practice and can be considered as a pharmacogenetic disease of obscure etiology occuring in man and pigs with a dominant inheritance. A close association with myopathy has been noted. Commonly used muscle relaxants or
In MH, skeletal muscle acutely and unexpectedly increases its oxygen consumption and lactate production, resulting in greater heat production, respiratory and metabolic acidosis, muscle ridigity, sympathetic stimulation, and increased cellular permeability. The best-accepted theory is that MH is due
Many cognitive aids are formatted in a step-by-step fashion with the intent that the aid will be accessed at the beginning of a critical event and that key behaviors will be performed in sequence.We hypothesized that, during simulated pediatric Poland syndrome, which is characterized by an absence of pectoralis muscles and their innervated nerves, is marked by variable chest wall defects due to deficits of 2nd, 3rd, 4th, and 5th ribs and costal cartilage. Additionally, there are other reported combined anomalies of the heart, lung, kidney,
Rhabdomyolysis is a potential life-threatening condition characterized by a rapid destruction of striated muscle cells. Causes include trauma, muscle hypoxia, drugs, malignant hyperthermia, infections, toxins and metabolic myopathies. We report a case of a 52-year-old man with hereditary
Heat stroke victims lack thermoregulatory control. Treatment includes immediate cooling, circulatory support and monitoring for secondary complications. Neuroleptic malignant syndrome is a complication of neuroleptic drug therapy; skeletal muscle hypertonicity helps distinguish this entity from heat
OBJECTIVE
High concentrations of hypoxanthine and urate have been found in the blood of rats who died suddenly during induced respiratory alkalosis as well as in cases of sudden death in malignant hyperthermia-susceptible pigs challenged with halothane. The origin of these metabolites is the
OBJECTIVE
To assess the efficacy and safety of helium as an insufflant for transabdominal laparoscopic renal surgery.
METHODS
The charts of all patients undergoing laparoscopic renal surgery with helium insufflation by a single physician between May 2003 and April 2006 were reviewed. Ventilatory
BACKGROUND
The pathophysiology of brain damage from hypoxia or ischemia has been ascribed to various mechanisms and cascades. Intracellular calcium overload and a calcium excitotoxic cascade have been implicated. It has been suggested that disturbances of endoplasmic reticulum calcium homeostasis
