Abstract
BACKGROUND Ultrasound-guided pectoralis muscle blocks (PECS I/II) are well established for postoperative pain control after mastectomy with reconstruction. However, optimal timing is unclear. We conducted a randomized controlled single-blinded single-institution trial comparing outcomes of block performed pre-incision versus post-mastectomy. METHOD Patients with breast cancer undergoing bilateral mastectomy with immediate expander/implant reconstruction were randomized to receive ultrasound-guided PECS I/II either pre-incision (PreM, n = 17) or post-mastectomy and before reconstruction (PostM, n = 17). The primary outcome was the average pain score using the Numerical Rating Score during post-anesthesia care unit (PACU) and inpatient stay, with the study powered to detect a difference in mean pain score of 2. Secondary outcomes included mean pain scores on postoperative day (POD) 2, 3, 7, 14, 90, and 180; pain catastrophizing scores; narcotic requirements; PACU/inpatient length of stay; block procedure time; and complications. RESULT No significant differences between the two groups were noted in average pain score during PACU (p = 0.57) and 24-h inpatient stay (p = 0.33), in the 2 weeks after surgery at rest (p = 0.90) or during movement (p = 0.30), or at POD 90 and 180 at rest (p = 0.42) or during movement (p = 0.31). Median duration of block procedure (PreM 7 min versus PostM 6 min, p = 0.21) did not differ. Median PACU and inpatient length of stay were the same in each group. Inpatient narcotic requirements were similar, as were length of stay and post-surgical complication rates. CONCLUSION Intraoperative ultrasound-guided PECS I/II block administered by surgeons following mastectomy had similar outcomes to preoperative blocks. TRIAL REGISTRATION This trial is registered with Clinical Research Information Service (NCT03653988).

Abstract
Background We hypothesized that patients who received an adductor canal block (ACB) in the operating room following unilateral total knee arthroplasty would have a lower oral morphine milligram equivalent (MME) consumption during the postanesthesia care unit (PACU) phase 1 recovery period compared to patients who received an ACB in the PACU. Methods This was a retrospective cohort study of patients who underwent robotic-assisted unilateral total knee arthroplasty under general anesthesia between March 1, 2020, and February 28, 2021, and received postoperative ACB either in the operating room or the PACU. Results A total of 36 and 178 patients received postoperative ACB in the operating room and PACU, respectively, and had median and interquartile range MME consumption in the PACU of 22.5 (20-40) mg and 30.0 (20-40) mg (P = 0.76), respectively. Patients who had an ACB performed in the operating room and PACU had median and interquartile ranges of time spent in the PACU of 101 (75-178) minutes and 186 (125-272) minutes (P < 0.01), respectively. Conclusion Patients who received an ACB in the operating room did not have a lower OME consumption than patients who received an ACB in the PACU but did have a shorter PACU length of stay.

J Pers Med 2021; 11:jpm11070622. [PMID: 34209054 PMCID: PMC8303976 DOI: 10.3390/jpm11070622] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Accepted: 06/29/2021] [Indexed: 12/19/2022] Open
Abstract
Adductor canal block (ACB) has gained popularity for postoperative pain control after total knee arthroplasty (TKA). However, its role in TKA has been questioned recently. Our study aimed to clarify the role of ACB in reducing postoperative pain after TKA and to elucidate an optimal timing to perform ACB for better outcomes. We conducted a comprehensive review of the perioperative records of 652 patients undergoing primary TKA from January 2019 to December 2019. Patients were divided into three groups: Group A received general anesthesia without ACB, Group B received ACB before inducing general anesthesia, and Group C received ACB at the post-anesthesia recovery unit (PACU). Patients in Groups B and C had lower pain visual analogue scale (VAS) scores than patients in Group A at the PACU. Opioid consumption was similar among the three groups; however, a slightly higher dose was required by Group A patients. Higher VAS scores were recorded in the ward in Group A than in Groups B and C with the leg at rest. In addition, higher VAS scores were recorded in Group A than in Groups B and C with the leg in continuous passive motion (CPM) training. More patients in Group A (34.9%) quit their first CPM training after a few cycles than those in Groups B (27.0%) and C (20.1%). Group A patients required a higher per kg dose of opioids in the ward than Groups B and C patients. Additionally, the hourly consumption of sevoflurane was similar among the three groups of patients, while Group A and C patients required a higher hourly per kg dose of intraoperative opioids than Group B patients. More patients in Group A (67.6%) and C (61.7%) developed intraoperative hypertension than patients in Group B (52.7%). There was no significant difference in PON (postoperative nausea), POV (postoperative vomiting), postoperative dizziness, or patient satisfaction among the three groups of patients. Group A patients had a longer length of hospital stay compared to Group B and C patients. In conclusion, preoperative ACB could be a better choice for patients undergoing TKA as it decreases intraoperative opioid consumption and facilitates a stable hemodynamic state during surgery.
