At present the in vitro caffeine-halothane contracture test is the only test to predict susceptibility to malignant hyperthermia (MH) with acceptable sensitivity and specificity. Anaesthesia is necessary for the excision of muscle bundles from the vastus lateralis muscle. MATERIAL AND METHODS. ⋯ Complete monitoring is necessary, even for this minor procedure: ECG, blood pressure, pulse oximetry, capnometry, measurement of body temperature and blood gas status. Differential diagnosis in negative test results. In patients who suffer an anaesthetic incident, the following disease must be considered: myopathies (especially the congenital myopathies and muscular dystrophies), respiratory problems due to pulmonary infection and obstruction, metabolic disorders of various origins, and the problem of masseter spasm.

The laryngeal mask airway was used to facilitate fibreoptic bronchoscopy under general anaesthesia in 140 adult patients. Following placement, the position of the mask was observed through the fibreoptic bronchoscope. Three different positions were identified. ⋯ No problems with ventilation or maintenance of an acceptable airway were encountered. In one patient repositioning of the laryngeal mask was necessary to allow the passage of the bronchoscope. One patient developed laryngospasm and required tracheal intubation.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Perioperative morbidity in patients randomized to epidural or general anesthesia for lower extremity vascular surgery. Perioperative Ischemia Randomized Anesthesia Trial Study Group.
Perioperative morbidity may be modifiable in high risk patients by the anesthesiologist's choice of either regional or general anesthesia. This clinical trial compared outcomes between epidural (EA) and general (GA) anesthesia/analgesia regimens in a group of patients at high risk for cardiac and other morbidity who were undergoing similarly stressful surgical procedures. ⋯ Carefully conducted epidural and general anesthesia appear to be associated with comparable rates of cardiac and most other morbidity in patients undergoing lower extremity vascular surgery. However, compared with general anesthesia, epidural anesthesia is associated with a lower incidence of reoperation for inadequate tissue perfusion and, therefore, may be advantageous for this surgical population.
