Background Gender-affirming pelvic surgery (GAPS) can be associated with significant postoperative pelvic pain. Given the lack of available peripheral nerve blocks to the perineum, intrathecal morphine (ITM) injection could offer a potent analgesic modality for this patient population. No prior studies to date have been performed examining the analgesic effects of intrathecal morphine for these patients. Methods This retrospective case-control study aims to understand the postoperative analgesic effects of intrathecal morphine for these patients with a historical comparison group of patients who did not receive intrathecal morphine. Results Fourteen patients presented for gender-affirming pelvic surgery over an eight-month period at a single institution and were offered intrathecal morphine for postoperative analgesia. Their analgesic results were compared to a similar historical group of 13 patients who were not offered or declined intrathecal morphine. Conclusions Intrathecal morphine injection is a potent analgesic modality for patients presenting for gender-affirming pelvic surgery.

Background: The study aim was to examine whether concomitant atrial fibrillation (AF) surgery at the time of mitral valve surgery in the elderly results in increased operative mortality (OM)., Methods: Medicare beneficiaries aged ≥65 years undergoing primary mitral valve repair or replacement between 2004 and 2006 were included. The cohort was divided into three groups: Group 1, AF- (n = 2,705); group 2, AF+AF surgery- (n = 2,119), and group 3, AF+AF surgery+ (n = 1,832). The primary outcomes were OM and long-term survival. A secondary outcome was the association between hospital annual mitral procedure volume and OM., Results: The unadjusted OM was 6.4% for group 1 (AF-), 10.3% for group 2 (AF+AF surgery-), and 7.1% for group 3 (AF+AF surgery+) (p = 0.0001). Adjusted OM for AF+AF surgery+ patients was not significantly different from that of AF- patients (OR 1.16, 95% CI 0.90-1.48), or from AF+AF surgery patients (OR 0.83, 95% CI 0.66-1.06). When comparisons were adjusted for differences in baseline characteristics, AF+AF surgery- patients were more likely to experience long-term mortality than AF- patients (HR 1.30, 95% CI 1.17-1.45), as well as AF+AF surgery+ patients (HR 1.17, 95% CI 1.05-1.31). An annual average mitral procedure volume ≤40 was independently predictive of OM (OR 1.42, 95% CI 1.13-1.78). The effect of institutional volume on mortality was strongest in those who received AF surgery (AF+AF surgery+) (HR 1.75, 95% CI 1.15-2.65), compared to those who did not undergo surgery (AF+AF surgery-) (OR 1.20, 95% CI 0.86-1.67)., Conclusions: Elderly patients undergoing mitral valve surgery do not appear to have an increased mortality when clinical judgment favored the performance of concomitant AF surgery.
