Abstract
Forty adult patients of two groups scheduled for surgical procedures involving the lower part of the body were enrolled in a study comparing the incidence and severity of hypotension during the first two hours of spinal anesthesia (SA). SA was induced either by 15mg of 0.5% hyperbaric bupivacaine (B group, 20 patients) or 0.5% hyperbaric bupivacaine (10mg) + 25 microgram fentanyl (FB group, 20 patients). Systolic (SBP), diastolic (DBP) and mean (MAP) arterial blood pressures were significantly lower in group B than in group FB. In group B, the lowest percentages of SBP, DBP and MAP pressure were 79%, 80% and 79% respectively, versus 87%, 8% and 8% for group FB. 70% of patients in group B and 40% in group FB developed hypotension. Total doses of ephedrine therapy were significantly higher in group B (30.4 mg ± 24.5) than group FB (12.6 mg ± 17.4).
