Description
Background: Subarachnoid blocks are the most popular method of administering regional aesthetic for procedures involving the knee and lower extremities. The possible benefits of a combined sciatic-femoral nerve block, however, make it an alternative that deserves investigation. Methods: Fourty adult patients, ranging in age from 18 to 65, who were scheduled for knee or below knee surgery were randomly assigned to either Group A (which involved a subarachnoid block) or Group B (which involved a combination sciatic-femoral nerve block). Contrasted with Group A’s 12 mg of 0.5% hyperbaric bupivacaine, Group B’s sciatic and femoral blocks were each administered 20 and 30 ml of 0.5% ropivacaine, respectively. Results: Compared to the separate sciatic and femoral groups, those undergoing combined preparation and preparedness for surgery took substantially longer. The subarachnoid group achieved a perfect block rate of 100%, but the sciatic-femoral group achieved an impressive 80% success rate. Statistical analysis revealed that the subarachnoid group had higher pulse rate and significantly lower systolic and diastolic blood pressures before to surgery. Within the first day following surgery, the combined sciatic-femoral group needed less analgesic overall and less analgesic duration. Conclusion: Both methods were problem-free. Although the combined sciatic-femoral block had a slightly lower success rate than the subarachnoid block, it had benefitted such as longer analgesia and less need for postoperative analgesics. Success rates and postoperative analgesic results should be considered while choosing between these approaches.
Abstract (English)
Background: Subarachnoid blocks are the most popular method of administering regional aesthetic for procedures involving the knee and lower extremities. The possible benefits of a combined sciatic-femoral nerve block, however, make it an alternative that deserves investigation. Methods: Fourty adult patients, ranging in age from 18 to 65, who were scheduled for knee or below knee surgery were randomly assigned to either Group A (which involved a subarachnoid block) or Group B (which involved a combination sciatic-femoral nerve block). Contrasted with Group A’s 12 mg of 0.5% hyperbaric bupivacaine, Group B’s sciatic and femoral blocks were each administered 20 and 30 ml of 0.5% ropivacaine, respectively. Results: Compared to the separate sciatic and femoral groups, those undergoing combined preparation and preparedness for surgery took substantially longer. The subarachnoid group achieved a perfect block rate of 100%, but the sciatic-femoral group achieved an impressive 80% success rate. Statistical analysis revealed that the subarachnoid group had higher pulse rate and significantly lower systolic and diastolic blood pressures before to surgery. Within the first day following surgery, the combined sciatic-femoral group needed less analgesic overall and less analgesic duration. Conclusion: Both methods were problem-free. Although the combined sciatic-femoral block had a slightly lower success rate than the subarachnoid block, it had benefitted such as longer analgesia and less need for postoperative analgesics. Success rates and postoperative analgesic results should be considered while choosing between these approaches.
