Midazolam compared with thiopentone as a hypnotic component in balanced anaesthesia: a randomized, double-blind study.

Midazolam is a short-acting water soluble benzodiazepine derivative. It is a hypnotic used for intravenous anaesthesia induction. The present investigation was designed in a prospective double-blind fashion to compare midazolam with thiopentone as hypnotic components in balanced anaesthesia. The study included 50 healthy patients undergoing relatively short surgical procedures. The results revealed that thiopentone is faster in onset than midazolam for induction of anaesthesia, with less variation of dose response. However, maintenance of anaesthesia was superior with midazolam, requiring fewer supplemental anaesthetic drugs, having better patient acceptance and providing more amnesia. Postoperative complications were very low with both techniques. Midazolam was surprisingly similar to thiopentone in most parameters including emergence time from anaesthesia. Midazolam is a new drug with potential both for induction of anaesthesia and maintenance of balanced anaesthesia.

Duration of intubation and ICU stay after open heart surgery.

One hundred four consecutive patients undergoing open heart surgery were studied to determine the duration of intubation and ICU stay associated with an anesthetic management protocol designed to avoid prolonged postoperative respiratory depression. The results document the feasibility and safety of early extubation and shortened ICU stay in patients having operations for ischemic and acquired valvular heart disease. Patients with complex congenital heart defects require significantly longer periods of respiratory support and intensive care.

Comparison of two benzodiazepines for anaesthesia induction: midazolam and diazepam.

Ro 21-3981 is a newly synthesized water soluble benzodiazepine derivative. Its pharmacological properties are similar to diazepam. This investigation was designed to establish the effective induction dosage of Ro 21-3981 and to compare it with diazepam for induction of anaesthesia. The ED50 for Ro 21-3981 induction is 0.15 mg/kg and ED 100 is 0.2 mg/kg. Ro 21-3981 is one and one-half times as potent as diazepam (0.3 mg/kg) and more rapid in action. There is significantly less pain on injection with Ro 21-3981 as compared to diazepam. Cardiovascular stability and apnoea were observed with both drugs. Ro 21-3981 is a promising anaesthetic induction drug that merits further human study.

Hepatic pathology and skin test reactions to trifluoro-acetylated autologous protein after repeated halothane anaesthesia in the guineapig.

The aetiology of the rare hepatic failure following halothane anaesthesia is not known. In an attempt to develop an experimental model, three groups of guineapigs were exposed to air or oxygen, a single 1% halothane administration, or five exposures of 1% halothane at weekly intervals. In an attempt to identify a hypersensitivity reaction, all animals were skin-tested with the common final metabolite of halothane, fluroxene and isoflurane: trifluoroacetic acid, prepared as a complex with autologous serum protein. Hepatic necrosis was found in all groups and did not correlate with positive skin reactions. There was an increase in fatty changes in the liver in animals anaesthetized with halothane.
