 To improve the perioperative care quality and operating room(OR)efficiency at Kagawa University Hospital, a post-anesthesia care unit(PACU)was introduced in November 2017. The PACU consists of six postoperative beds and two pre-anesthesia beds, located at the center of the OR floor. The structure and operation of our PACU are described in this study, which evaluated the impacts of the PACU on early postoperative pain management and OR turnover time.

 We retrospectively analyzed cases of patients who underwent a unicompartmental knee arthroplasty before and after the PACU’s implementation. Postoperative pain scores and analgesic intervensions were compared between the groups. In the PACU group, 33% of the patients required analgesic intervention within 30 min postoperatively, despite reporting minimal pain at emergence from surgery. Early pain control in the PACU reduced the hospital’s ward-based analgesic needs and improved the patients’ pain scores on the first postoperative day.

 However, no significant reduction in the overall OR turnover time was observed. Only the in-room observation time after extubation was shortened.

 These results indicate that our PACU enables accurate early assessments and interventions and improves the quality of postoperative analgesia. However, the presence of a PACU alone does not improve an OR’s efficiency. Further workflow optimization, including the optimization of patient setup and patient transport, is needed.
