Preemptive caudal anesthesia on back pain after lumbar discectomy: a randomized and controlled study

Area of Science:

• Anesthesiology
• Neurosurgery
• Pain Management

Background:

• Post-operative pain is a significant concern following lumbar disc herniation surgery.
• Effective pain management is crucial for patient recovery and functional restoration.

Purpose of the Study:

• To evaluate the efficacy of preemptive caudal analgesia in reducing early post-operative surgical and muscle-related pain.
• To assess the impact of caudal bupivacaine or bupivacaine with methylprednisolone on pain intensity and functional capacity.

Main Methods:

• A prospective, randomized study involving 120 patients with single-level lumbar disc herniation.
• Caudal epidural injections administered 20 minutes pre-surgery, with patients divided into three groups.
• Pain assessment using the Visual Analog Scale (VAS) pre-operatively and at various post-operative time points.

Main Results:

• Significant reductions in post-operative pain were observed across all groups compared to baseline.
• Statistical significance in pain reduction was noted at 1, 2, 4, and 24 hours post-surgery between specific groups.
• A significant difference in pain intensity was found between the 24-hour mark and the 1-week follow-up in Groups 1 and 2.

Conclusions:

• Preemptive caudal injection of bupivacaine, alone or with methylprednisolone, is a safe and effective strategy for managing post-operative pain.
• This approach significantly reduces pain and improves functional capacity in patients treated for lumbar disc herniation.
