Intraperitoneal lidocaine for postoperative pain after laparoscopy

Area of Science:

• Anesthesiology
• Surgical Pain Management

Background:

• Controversy surrounds the efficacy of intraperitoneal local anesthetics for post-laparoscopic cholecystectomy pain.
• Investigating the clinical value of intraperitoneal lidocaine is crucial.

Purpose of the Study:

• To evaluate the effectiveness of intraperitoneal lidocaine in managing pain after laparoscopic cholecystectomy.
• To assess the impact of intraperitoneal lidocaine on postoperative pain intensity, analgesic consumption, and recovery.

Main Methods:

• A double-blind study involving 50 patients undergoing laparoscopic cholecystectomy.
• Lidocaine or saline solution was administered intraperitoneally at the end of surgery.
• Pain intensity, analgesic use, respiratory function, and side effects were systematically recorded.

Main Results:

• Intraperitoneal lidocaine significantly reduced the incidence, severity, and duration of shoulder pain.
• Patients receiving lidocaine reported less abdominal pain and experienced "no pain on deep inspiration" more frequently.
• Analgesic consumption was significantly lower in the lidocaine group within 24 hours post-surgery.

Conclusions:

• Intraperitoneal lidocaine offers a simple and effective method for long-lasting pain reduction after a single administration.
• This approach demonstrates significant clinical value in managing postoperative pain following laparoscopic cholecystectomy.
