Intercostal nerve block with thoracoabdominal and flank incisions

Area of Science:

• Anesthesiology
• Thoracic Surgery
• Nephrology

Background:

• Postoperative pain management is crucial after major abdominal surgery.
• Intercostal nerve blocks are used for analgesia but their impact on specific surgical outcomes requires further investigation.
• Flank and thoracoabdominal incisions present unique challenges for pain control and recovery.

Purpose of the Study:

• To evaluate the efficacy of intraoperative intercostal nerve block with bupivacaine hydrochloride.
• To assess the impact on postoperative pain, analgesic requirements, and complications.
• To determine effects on the day of ambulation and oral fluid intake.

Main Methods:

• A double-blind, placebo-controlled study involving 90 patients.
• Patients underwent either rib-resecting thoracoabdominal or flank incisions.
• Intercostal nerve block with bupivacaine hydrochloride or placebo was administered intraoperatively.

Main Results:

• Significant reduction in postoperative analgesic requirements in the bupivacaine group.
• No significant difference in the day of ambulation or oral fluid intake between groups.
• Reduced incidence of postoperative atelectasis in the bupivacaine-treated group (4/45) compared to placebo (10/45).

Conclusions:

• Intraoperative intercostal nerve block with bupivacaine is an effective adjuvant for managing postoperative pain.
• This nerve block can decrease the need for analgesics and reduce the incidence of atelectasis after flank surgery.
• Further research may explore broader applications in thoracic and abdominal procedures.
