Haemodynamic effects of midazolam and thiopentone during induction of anaesthesia for coronary artery surgery. 1982

D Al-Khudhairi, and J G Whitwam, and M K Chakrabarti, and H Askitopoulou, and E M Grundy, and S Powrie

The cardiovascular effects of thiopentone 3 mg kg-1 and midazolam 0.3 mg kg-1 were observed during induction of anaesthesia in 16 premedicated patients about to undergo myocardial revascularization. There were no significant changes in either group in cardiac output or central venous pressure. The heart rate in both groups showed an increase at 3 min and thereafter returned to control values. After 3 min, there was a significant decrease in both arterial pressure and peripheral resistance by 12% and 15% (mean values) respectively from control values in the group receiving midazolam, whereas after thiopentone the peripheral resistance increased by approximately 13% and was not affected by a further dose of thiopentone 1 mg kg-1.

D008874 Midazolam A short-acting hypnotic-sedative drug with anxiolytic and amnestic properties. It is used in dentistry, cardiac surgery, endoscopic procedures, as preanesthetic medication, and as an adjunct to local anesthesia. The short duration and cardiorespiratory stability makes it useful in poor-risk, elderly, and cardiac patients. It is water-soluble at pH less than 4 and lipid-soluble at physiological pH.
