[Spinal anesthesia with low dose sufentanil-bupivacaine in transurethral resection of the prostate].
OBJECTIVE
To explore the clinical efficacy of intrathecally administered low dose sufentanil-bupivacaine in transurethral resection of the prostate (TURP). METHODS. Ninety patient (ASA I - III) undergoing TURP were randomly divided into 3 groups (n = 30); Group A, B and C. Group A received 7.5 mg bupivacaine + 5 microg sufentanil + 10% glucose; Group B received 7.5 mg bupivacaine + 7.5 microg sufentanil + 10% glucose; Group C received 15 mg bupivacaine + 10% glucose. The volume was 3 mL in every group. SP, DP, HR, SpO2, the degree of motor and sensory blockade and the side effect were observed.


RESULTS
SP/DP was significantly decreased in Group C than that in Group and Group B (p<0.05), HR and SpO2 in group B were decreased to different degrees 15 min after the injection (p<0.05). The complete recovery time of motor nerve blockade and the regression time of sensory blockade were obviously prolonged in Group C (p<0.05). There were no significant differences in analgesic effect among the three groups during the operation, but the incidence of pruritus was higher in both group A and Group B than that in Group C during the first 24 hours after the injection.


CONCLUSIONS
Spinal anesthesia with low dose sufentanil-bupivacaine possesses relatively steady hemodynamics. The blockade degree of motor and sensory blockade in this spinal anesthesia is lower than that in standard spinal bupivacaine in TURP.
