Operative laparoscopy and postoperative pain relief.

Area of Science:

• Anesthesiology
• Surgical Pain Management

Background:

• Postoperative pain is a common concern following laparoscopic surgery.
• Effective pain management strategies are crucial for patient recovery and satisfaction.

Purpose of the Study:

• To evaluate the efficacy of intraperitoneal (IP) lidocaine and intraincisional bupivacaine in reducing immediate postoperative pain and discomfort.
• To assess the safety of these local anesthetic instillations during operative laparoscopy under general anesthesia.

Main Methods:

• A prospective randomized study involving 54 participants undergoing operative laparoscopy.
• Three groups were compared: IP lidocaine + intraincisional bupivacaine, intraincisional bupivacaine only, and no additional local anesthetics (controls).
• Pain was assessed using modified McGill Present Pain Intensity scores and analgesic use.

Main Results:

• Patients receiving IP lidocaine demonstrated significantly lower McGill Present Pain Intensity scores and reduced narcotic use in the recovery room (P < 0.05).
• The mean maximum plasma lidocaine level was 1.01 ± 0.25 μg/mL, indicating a safe systemic absorption profile.
• The combination of IP lidocaine and incisional bupivacaine was associated with the greatest reduction in pain.

Conclusions:

• Peritoneal lidocaine and incisional bupivacaine instillation is a safe and effective method for managing postoperative pain after operative laparoscopy.
• This multimodal approach enhances patient comfort in the immediate postoperative period.
