Analgesic efficacy and serum ropivacaine concentration of postoperative programmed intermittent bolus infusion with serratus anterior plane block in patients undergoing minimally invasive cardiac surgery: A randomized, double-blind, controlled trial.

ABSTRACT:

Purpose

Minimally invasive cardiac surgery (MICS) involves fewer complications than median sternotomy. However, difficulties in post-MICS analgesia can undermine these advantages. The serratus anterior plane block (SAPB), an effective analgesic for thoracic surgery, could benefit post-MICS analgesia using programmed intermittent bolus infusion (PIBI). We investigated whether PIBI with SAPB can reduce post-MICS fentanyl administration and evaluated its safety profile.

Methods

This randomized, double-blind, controlled trial included 20 patients (age 20-80 years; Eastern Cooperative Oncology Group Performance Status 0-II; scheduled for elective MICS) randomly allocated to two groups (SAPB or control). All patients underwent preoperative SAPB with catheterization, followed by ei
