Comparison between spinal anaesthesia and sciatic-femoral block for arthroscopic knee surgery

Area of Science:

• Anesthesiology
• Orthopedic Surgery
• Regional Anesthesia

Background:

• Arthroscopic knee surgery requires effective anesthesia and analgesia.
• Spinal anesthesia and peripheral nerve blocks are common anesthetic techniques.
• Comparing these techniques is crucial for optimizing patient outcomes and recovery.

Purpose of the Study:

• To compare spinal anesthesia with sciatic-femoral nerve block for arthroscopic knee surgery.
• To evaluate hemodynamic changes, anesthesia quality, and postoperative recovery.
• To assess patient satisfaction and side effects associated with each technique.

Main Methods:

• A randomized study of 32 patients undergoing arthroscopic knee surgery.
• Group S received unilateral spinal anesthesia (bupivacaine).
• Group B received sciatic-femoral nerve block (mepivacaine) with nerve stimulation.

Main Results:

• Significant differences in heart rate changes at 10, 15, and 30 minutes (increase in Group B, decrease in Group S).
• First urine output occurred earlier in Group B (200 min) compared to Group S (269 min).
• No significant differences reported in intraoperative anesthesia, postoperative analgesia, motor block, or patient satisfaction.

Conclusions:

• Sciatic-femoral nerve block is a safe and effective alternative to spinal anesthesia for arthroscopic knee surgery.
• This block may facilitate earlier hospital discharge.
• Further research could explore long-term outcomes and cost-effectiveness.
