Summary
Transverse Thoracic Muscle Plane Block (TTMPB) significantly reduced pain and opioid use after cardiac surgery. This technique also improved respiratory function, offering better postoperative analgesia compared to conventional methods.
Area of Science:
- Pain Management
- Thoracic Surgery
- Regional Anesthesia
Background:
- Acute surgical pain post-cardiac surgery leads to chronic pain and opioid dependence.
- Effective pain management is crucial for recovery and reducing complications.
Purpose of the Study:
- To compare pain scores, patient-controlled analgesia (PCA) fentanyl use, and spirometry values.
- To evaluate the efficacy of Transverse Thoracic Muscle Plane Block (TTMPB) versus conventional opioid strategy in cardiac surgery patients.
Main Methods:
- Randomized controlled trial with 40 adult patients undergoing cardiac sternotomy.
- Intervention group received TTMPB; control group received conventional opioid strategy.
- Pain scores (VAS), PCA fentanyl consumption, and incentive spirometry were measured postextubation.
Main Results:
- TTMPB significantly reduced pain scores at rest and on movement.
- PCA fentanyl consumption was significantly lower in the TTMPB group.
- Improved spirometry volume was observed in the TTMPB group compared to controls.
Conclusions:
- TTMPB provides effective postoperative analgesia for cardiac surgery.
- TTMPB reduces pain, opioid requirements, and enhances respiratory function.
- TTMPB is a valuable technique for managing pain after sternotomy.
