Failure of phenylephrine to prolong isobaric bupivacaine spinal anesthesia in elderly patients.

Background And Objectives: The effects of phenylephrine on the duration of spinal anesthesia produced by plain bupivacaine were investigated in a double-blind study of 100 elderly patients.

Methods: Each patient received a basic solution of 3 ml 0.5% plain bupivacaine to which was added either 1 ml physiologic saline, 0.

[Metaraminol does not prolong the duration of spinal anesthesia using glucose-free bupivacaine in the upper dermatomes].

The effects of metaraminol on the duration of plain bupivacaine spinal anaesthesia were investigated in a double-blind study of 80 elderly patients. Each patient received a basic solution of 0.5% plain bupivacaine to which was added either physiological saline, or 1 mg, 2 mg or 3 mg metaraminol.

[Comparative study of general and spinal anesthesia in elderly women in hip surgery].

The choice between regional versus general anaesthesia for elderly patients undergoing hip surgery is debated. It is vitally important to see if the type of anaesthetic administered affects per- and postoperative morbidity and mortality. Seventy women more than 75 yr old suitable for spinal anaesthesia were included in this study.
