Comparison of intrrathecal hyperbaric bupivacaine and hyperbaric bupivacaine+sufetanil combination in lower extremity surgery

We aimed to evaluate the effects of intrathecal sufentanil added to hyperbaric bupivacaine for lower extremity surgery. After obtaining approval from the ethics committee, fifty patients (ASA I-II) were included in this study and were allocated randomly to two groups of 25 each. 10 mg hyperbaric bupivacaine +10 µg sufentanil was injected to Group S and the same döşe of hyperbaric bupivacaine given to group K with 2 mL %0.9 NaCI, four mL solution was usen in both groups for İT anesthesia. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), peripheral oxygen saturation (SpO2), sensory and motor block were recorded every 5 minutes during first 30 min, every 10 min fort he following 30 min and every 15 min intervals in the operation period Intraoperative/postoperative side effects and postoperative analgesic requirements were recorded. HR, SBP, DBP and MBP were decreased significantly in both groups when compared with control values and no significant difference were noted between the groups. The onset time of sensory block was shorter in groups S and sensory block was higher in Groups S than Group K. The duration of analgesia was longer in Group S than Group K (p<0.05). In conclusion; intrathecal 10 µg sufentanil added to hyperbaric bupivacaine for lower extremity surgery increased the duration of analgesia in the early postoperative period. 10 µg sufentanil plus hyperbaric bupivacaine provided to improve both the quality and duration of analgesia in this procedures. Bacause this combination had no adverse effect except pruritus, we concluaded that it can be used safety in lower extremity surgery.
