Effect of abdominal binder on shoulder pain after laparoscopic gynecologic surgery: A randomized, controlled trial.

BACKGROUND: To evaluate the impact of abdominal binder (AB) use on postoperative shoulder pain in patients recovering from laparoscopic gynecologic surgery. METHODS: This was a prospective randomized study conducted in a tertiary teaching hospital. Overall, 144 patients underwent laparoscopic gynecologic surgery. The postoperative use of an AB for 24 hours was added to the pulmonary recruitment maneuver. RESULTS: Of 144 consenting patients, 72 patients each were allocated to the AB and control groups, respectively, and 14 patients were excluded. Finally, 130 patients were analyzed, with 68 in the AB group and 62 in the control group. There was no difference in the incidence of postoperative shoulder pain between the 2 groups (55.9% vs 56.5%, P = 1.000). The severity of the worst shoulder pain, measured using a numerical rating scale, did not differ between the 2 groups (Median [interquartile range] 2 [0-5] vs 2 [0-5]; P = .865). The severity of surgical site pain, pain and nausea medications, and the ambulation time were not different in the 2 groups. CONCLUSION: The use of an AB was not beneficial for postoperative shoulder pain following laparoscopic gynecologic surgery. Surgical site pain, ambulation time, and postoperative nausea and vomiting were not improved with the use of an AB.

Early Postoperative Fever and Atelectasis in Patients Undergoing Upper Abdominal Surgery.

BACKGROUND: Atelectasis is a common complication after upper abdominal surgery and considered as a cause of early postoperative fever (EPF) within 48 hours after surgery. However, the pathophysiologic mechanism of how atelectasis causes fever remains unclear. STUDY DESIGN: Data for adult patients who underwent elective major upper abdominal surgery under general anesthesia at Seoul National University Hospital between January and December of 2021 were retrospectively analyzed. The primary outcome was the association between fever and atelectasis within 2 days after surgery. RESULTS: Of 1,624 patients, 810 patients (49.9%) developed EPF. The incidence of atelectasis was similar between the fever group and the no-fever group (51.6% vs 53.9%, p = 0.348). Multivariate analysis showed no significant association between atelectasis and EPF. Culture tests (21.7% vs 8.8%, p < 0.001) and prolonged use of antibiotics (25.9% vs 13.9%, p < 0.001) were more frequent in the fever group compared to the no-fever group. However, the frequency of bacterial growth on culture tests and postoperative pulmonary complications within 7 days were similar between the two groups. CONCLUSIONS: EPF after major upper abdominal surgery was not associated with radiologically detected atelectasis. EPF also was not associated with the increased risk of postoperative pulmonary complications, bacterial growth on culture studies, or prolonged length of hospital stay.
