METHODS: A prospective randomized comparative study on 120 female patients, aged 20-50 years with a BMI of 30-40 kg/m2 and American Society of Anesthesiologists physical status II, scheduled for elective surgery under spinal anesthesia, was included in the study. Patients were randomly divided into two groups, with 60 patients in each group. Group P uses the paramedian approach for spinal anesthesia, and group M uses the midline approach for spinal anesthesia.
RESULTS: Low back pain incidence was lower in group P than in group M at seven days, but at one month and after, its incidence remained the same in both groups. No difference in the severity of pain was observed.
CONCLUSIONS: The occurrence of back pain in the first seven days of surgery was significantly more frequent with the median approach. The pain severity decreased as the time passed from day seven to three months of follow-up. There is no difference in the severity of pain with either approach at different intervals.
方法:对120名女性患者进行前瞻性随机比较研究,年龄20-50岁,BMI为30-40kg/m2,美国麻醉医师协会的身体状况为II,计划在脊髓麻醉下进行择期手术,包括在研究中。将患者随机分为两组,每组60例。P组采用辅助方法进行脊髓麻醉,M组采用中线入路进行脊髓麻醉。
结果:第7天,P组腰背痛发生率低于M组,但在一个月后,两组的发病率保持相同.没有观察到疼痛严重程度的差异。
结论:手术前7天发生背痛的频率明显高于中位方法。随着随访的第7天至3个月的时间过去,疼痛严重程度降低。两种方法在不同的时间间隔下疼痛的严重程度没有差异。
