As the indications for and the volume of arthroscopic rotator cuff repair increase, it is important to optimize perioperative care to minimize postoperative complications and health care costs. We sought to investigate if the anesthesia type used affects the rate of postoperative complications in patients undergoing arthroscopic rotator cuff repairs. We conducted a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database to identify patients undergoing arthroscopic rotator cuff repair from 2014 to 2018. Patients were divided into 3 cohorts: general anesthesia, regional anesthesia, and combined general plus regional anesthesia. Bivariate and multivariate analyses with stepwise technique were performed on data related to patient demographics, smoking history, functional status, medical comorbidities (ie, bleeding disorders, chronic obstructive pulmonary disease, and dialysis), and postoperative outcomes within 30 days of discharge. To assess the independent risk factors for postoperative complications, demographics and medical comorbidities were included in the multivariate analyses for any variables that derived P values <.20. Of 24,677 total patients undergoing arthroscopic rotator cuff repair, 15,661 (63.5%) had general anesthesia, 889 (3.6%) had regional anesthesia, and 8127 (32.9%) received combined general plus regional anesthesia. Patients who received general anesthesia rather than regional anesthesia were more frequently white (76.8% vs 74.8%, respectively) and had a medical history of hypertension (47.9% vs 41.8%, respectively), smoking (14.9% vs 12.4%, respectively), and chronic obstructive pulmonary disease (3.4% vs 1.6%, respectively). Compared with patients receiving general anesthesia, those receiving combined general plus regional were more likely to have higher American Society of Anesthesiologists class and a smoking history. Following adjustment, patients who underwent regional anesthesia had a decreased risk for postoperative admission compared with patients who had general anesthesia. Patients who underwent combined regional plus general anesthesia had decreased rates of wound complications and readmission compared with those who received general anesthesia. Among patients undergoing arthroscopic rotator cuff repair, this retrospective study found a significantly higher rate of respiratory and cardiac comorbidities with general anesthesia compared with regional anesthesia. When controlling for these confounders, the use of regional anesthesia was still associated with lower rates of postoperative readmission compared with the general and combined subgroups. Patients receiving combined general plus regional anesthesia had decreased rates of wound complications and readmittance compared with general anesthesia. These findings may influence anesthetic choice in minimizing postoperative complications for rotator cuff repairs.
