ABSTRACT
BACKGROUND:
The purpose of this study is to compare the anesthetic characteristics in elderly patients who remain in sitting position for 2 min compared with patients that are placed in supine position after induction of spinal anesthesia.METHODS:
Fifty-seven patients scheduled for transurethral surgery were randomized to assume supine position immediately after 6.5 mg hyperbaric bupivacaine were injected (L group) or to remain in the sitting position for 2 minutes before they also assumed the supine position (S group). Analgesic levels were assessed bilaterally, using pin-prick. Motor block was scored using a 12-point scale. The mean arterial pressure and heart rate were also recorded.RESULTS:
Sensory block levels were significantly lower at all time points for the L group. However, there were no significant differences in the degree of the motor block and hemodynamic changes between the two groups. However, in the L group, ephedrine or atropine were administered to three patients.CONCLUSIONS:
We concluded that performing a spinal anesthesia in sitting position was technically easier and induced less hypotension.Key words
