Case ReportsSuspected malignant hyperthermia syndrome in a miniature pot-bellied pig anesthetized with isoflurane.
Hyperthermia developed in a 7-week-old Vietnamese pot-bellied pig after isoflurane anesthesia for routine ovariohysterectomy. Shivering and a sudden increase in heart rate were noticed 90 minutes after anesthetic induction, both of which persisted throughout the remaining anesthetic period. ⋯ Malignant hyperthermia was suspected to be the cause of the clinical signs in this pig, but specific tests to support this diagnosis were not performed. This report illustrates that hyperthermia may develop in this breed of swine during isoflurane anesthesia, and rectal temperature should be monitored during and after the anesthetic period.

Six cases of acute transient enlargement of the parotid gland under general anesthesia, so called anesthesia mumps, are reported. Patient 1 was placed in the left lateral position and the left parotid gland was subsequently observed to be diffusely enlarged. With five patients in the prone position, bilateral parotid gland enlargement was observed. ⋯ Mechanical compression by sheet amadou may have produced the swelling in the patient who was placed in a lateral position. In the prone position, changes in the autonomic nervous system during surgical procedures and anesthesia, vascular congestion resulting from the surgical position, an overactive pharyngeal reflex stimulated by endotracheal intubation and mechanical ventilation are discussed as possible causes. Evaluation of the occurrence and clinical course of anesthesia mumps provided useful diagnostic and management data.

Define the ranges for normal vital signs during general anesthesia. ⋯ Clinicians recognize ranges for vital signs during uneventful anesthesia. These CORs may differ from one stage of anesthesia to the next. Transgressions of these ranges are common. Not all transgressions are treated.

Randomized Controlled Trial Clinical TrialEvaluation of flumazenil for reversing the effects of midazolam-induced conscious sedation or general anesthesia.
To evaluate the effectiveness of flumazenil in reversing midazolam-induced conscious sedation and general anesthesia, we gave either flumazenil or placebo to 55 patients in a double-blind manner after surgery. Whether surgery was done under conscious sedation (CS group) or general anesthesia (GA group) depended on the procedure. Recovery was assessed by an Observer Assessment of Alertness and Sedation (OAAS) Scale, Finger-Nose (F-N) test, and picture recall and recognition. ⋯ In both groups, picture recall and recognition improved significantly immediately after flumazenil administration, but this improvement was generally not sustained for pictures shown at later times. These results imply that flumazenil is beneficial for reversing amnesia briefly after midazolam-induced sedation. However, flumazenil hastens recovery only when larger doses of midazolam are used for general anesthesia.
