RESUMO
PURPOSE: To determine the incidence and factors contributing to postspinal anesthesia (SPA) low back pain (LBP) in patients undergoing nonobstetrical surgeries. DESIGN: A prospective 1-year follow-up study. METHODS: Patients having nonobstetrical surgery using SPA were included. The patients were followed up through phone calls and interviews every postoperative day for the first week, weekly for a month, and then monthly for a year after SPA. Patients' duration of LBP, duration of surgery, and need for LBP treatment were recorded. FINDINGS: Of 410 patients, 5.8% (24 patients) experienced LBP. The incidence of LBP did not have a significant correlation with the recorded variables (P > .05). There was a negative significant correlation between duration of LBP and duration of surgery (r = -0.5096; P = .001). Of the 24 patients experiencing LBP, 16.7% (four patients) experienced it for less than 1 day, 66.7% (16 patients) 1 to 7 days, 16.7% (four patients) more than 7 days, and only one patient (4.2%) for up to 17 days. Special LBP treatment was not needed in any of the patients. CONCLUSIONS: The incidence of LBP was very low, and those patients undergoing nonobstetrical surgery and receiving SPA did not experience persistent LBP.
