Serratus posterior superior intercostal plane block: novel block for minimal invasive cardiac surgery -A report of three cases

Median sternotomy is the standard approach for cardiac surgery (CS). However, conventional CS has some disadvantages such as severe pain, a long hospital stay, and cosmetic concerns. Minimally invasive cardiac surgery (MICS) is not associated with these disadvantages [1]. MICS facilitates earlier mobilization and faster postoperative recovery. Incision types for MICS include upper/lower hemisternotomy and right/left anterior minithoracotomy.
