Background and Aims This study aims to assess the effectiveness of the pectoral nerve II (PECS II) block in diminishing postoperative pain, reducing opioid consumption, and enhancing the overall quality of recovery in patients undergoing robot-assisted transaxillary thyroidectomy (RATT).

Methods The Ethics Committee of Seoul University, Mary’s Hospital (KC22EISI0542) approved this prospective, randomized controlled trial (September 29, 2022). This trial involved 83 patients, aged between 19 and 60, scheduled for elective RATT. These participants were then allocated into two groups: 42 received the PECS II block (block group), and 41 did not (non-block group). The study’s primary focus was on evaluating postoperative pain levels. Secondary measures included the frequency of opioid use and the self-assessed quality of recovery post-surgery. Pain levels were gauged using the Visual Analog Scale at intervals of 1, 4, 24, and 48 hours post-surgery, alongside monitoring rescue opioid usage. On the day of discharge, patients completed the Korean version of the Quality of Recovery-15 (QoR-15K) questionnaire.

Results Data indicated that the block group experienced significantly lower levels of postoperative pain at the 1, 4, and 24-hour marks compared to the non-block group. The latter exhibited a higher dependency on opioids, notably in the Post Anesthesia Care Unit. The QoR-15K outcomes suggested superior pain management in the block group. Other recovery aspects, such as physical comfort and emotional well-being, were similarly rated in both groups.

Conclusions The PECS II block demonstrates considerable potential in enhancing the postoperative recovery experience for RATT patients, primarily through improved pain management.

  • PECS II block
  • robot-assisted transaxillary thyroidectomy.
