Continuous extrapleural intercostal nerve block with bupivacaine effectively reduced postoperative pain and improved lung function in patients undergoing pleurectomy. This safe analgesia method enhances respiratory recovery after surgery.

Area of Science:

  • Anesthesiology
  • Thoracic Surgery
  • Pain Management

Background:

  • Postoperative pain and impaired pulmonary function are significant concerns following pleurectomy.
  • Effective pain management is crucial for improving patient recovery and respiratory mechanics.

Purpose of the Study:

  • To evaluate the efficacy of continuous extrapleural intercostal nerve block using bupivacaine for postoperative pain control and pulmonary function enhancement after pleurectomy.

Main Methods:

  • A randomized, double-blind trial involving 16 patients undergoing pleurectomy.
  • Patients received either continuous extrapleural intercostal block with bupivacaine or a placebo (saline).
  • Pain was assessed using a visual analogue scale, and pulmonary function (peak expiratory flow, FEV1, FVC) was measured preoperatively and for five days postoperatively.

Main Results:

  • The bupivacaine group reported significantly lower pain scores at all measured time points compared to the placebo group.
  • Patients receiving bupivacaine required less additional opioid analgesia (papaveretum).
  • Pulmonary function measurements showed significantly better preservation and faster recovery in the bupivacaine group compared to the control group.

Conclusions:

  • Continuous extrapleural intercostal nerve blockade with bupivacaine is a safe and effective method for managing postoperative pain after pleurectomy.
  • This technique significantly improves respiratory mechanics and promotes faster pulmonary function recovery.
