Key result
Ultrasound-guided transversus thoracic muscle plane block significantly reduced the percentage of patients requiring additional postoperative morphine (P<0.015) and total morphine dose (8±0.74 mg).
Why the study?
Transverse thoracic block is a new perioperative analgesic method for post-sternotomy discomfort, prompting evaluation of ultrasound-guided transversus thoracic muscle plane block efficacy in cardiac surgery involving sternotomy.
Does ultrasound-guided transversus thoracic muscle plane block with bupivacaine reduce postoperative pain and opioid requirements in patients undergoing heart surgery with sternotomy?
Population
60 patients undergoing heart surgery, including sternotomy
Comparison
TTPB with 0.25% bupivacaine vs TTPB with saline (both with GA)

Does ultrasound-guided transversus thoracic muscle plane block with bupivacaine reduce postoperative pain and opioid requirements in patients undergoing heart surgery with sternotomy?
p-value: p=<0.015
Ultrasound-guided transversus thoracic muscle plane block with bupivacaine significantly reduces postoperative pain, morphine requirements, extubation time, and ICU stay in patients undergoing sternotomy.
Shokri et al. (2021) conducted an RCT in Post-sternotomy pain (n=60). Ultrasound-guided transversus thoracic muscle plane block (TTPB) vs. General anesthesia with 15 mL saline injected on either side was evaluated on Percentage of patients requiring additional morphine (p=<0.015). Ultrasound-guided transversus thoracic muscle plane block significantly reduced the percentage of patients requiring additional postoperative morphine (P<0.015) and total morphine dose (8±0.74 mg).
