Evaluation of the Spread and Effect of Local Anesthetic Administered Using Thoracic Muscle Plane Block on Internal Thoracic Artery Grafts
Authors' conclusion
TTPB can be performed safely on patients undergoing coronary artery bypass grafting using ITAs without affecting the ITA graft properties and patency.
Study context
- Population
- Adults undergoing cardiac surgery with median sternotomy; TTPB with 20 mL local anesthetic each side at T4-T5
- Participants
- 47 vs 30
- Exposure
- Transthoracic echocardiography vs T-shaped ultrasound probe
- Transthoracic echocardiographyn = 47
- T-shaped ultrasound proben = 30
- Outcome
- Spread and effect of TTPB local anesthetic in peri-ITA tissue
Methodological detailssingle hospital
- Single hospital
