Paravertebral block anesthesia for inguinal hernia repair.

Area of Science:

• Anesthesiology
• Regional Anesthesia
• Surgical Procedures

Background:

• Anesthesia choice for inguinal hernia repair is debated, with local anesthesia favored but general/spinal anesthesia commonly used.
• Paravertebral block, successful in breast cancer surgery, offers prolonged sensory block, reduced postoperative pain, nausea, and faster recovery.
• These benefits align with the needs of ambulatory hernia surgery.

Purpose of the Study:

• To evaluate the efficacy and safety of thoracic/lumbar paravertebral block for ambulatory inguinal hernia repair.
• To assess postoperative pain, recovery time, and patient satisfaction with this regional anesthesia technique.

Main Methods:

• Thirty consecutive patients undergoing ambulatory inguinal hernia repair received thoracic/lumbar paravertebral block.
• Block placement time, success rate, need for supplemental anesthesia, and intraoperative pain management were recorded.
• Postoperative outcomes including pain onset, duration of sensory block, pain medication use, and return to activities were analyzed.

Main Results:

• Effective anesthesia was achieved in 28 of 30 patients (93.3%), with two requiring general anesthesia.
• Average block placement time was 12.3 minutes; 10 cases required supplemental sedation or local anesthesia for intraoperative pain.
• Postoperative pain onset averaged 15 hours, sensory block duration was 13 hours, and 82% of patients reported high satisfaction.

Conclusions:

• Thoracic/lumbar paravertebral block is an effective and safe anesthetic technique for ambulatory inguinal hernia repair.
• The technique is associated with minimal complications, reduced postoperative pain, and high patient satisfaction.
• It facilitates a shortened hospital stay and rapid return to normal activities, suitable for ambulatory settings.
