Efficacy of quadratus lumborum block in the treatment of acute and chronic pain after cesarean section: A systematic review and meta-analysis based on randomized controlled trials.

BACKGROUND: This analysis aimed to explore the analgesic effects of quadratus lumborum block on acute and chronic postoperative pain among patients undergoing cesarean section. METHODS: PubMed, Cochrane, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP databases for Randomized Controlled Trials (RCTs) that focused on the use of quadratus lumborum block in cesarean section procedures were searched from the inception of the databases until December 2022. Studies were screened based on inclusion and exclusion criteria, and were then conducted for quality assessment and data extraction. Meta-analysis was performed using Stata 15.0 software. Two researchers independently screened the studies, extracted data, and evaluated the risk of bias for the included studies. In case of any disagreements, it was resolved by consultation with a third party opinion. RESULTS: A total of 21 studies involving 1976 patients were finally included, with an overall acceptable study quality level. Compared to the control group, the administration of Quadratus Lumborum Block (QLB) resulted in significant reduction in the postoperative 24-hour visual analog scale (VAS) score (WMD = -0.69, 95% CI: -1.03 ~ -0.35, P < .001) and the consumption of opioid analgesics within 24 hours after surgery (WMD = -2.04, 95% CI: -2.15 ~ -1.92, P = .002). The incidence of chronic pain 3 months QLB (OR = 0.41, 95% CI: 0.09 ~ 1.88, P = .253) and 6 months (OR = 0.83, 95% CI: 0.33 ~ 2.07, P = .686) after surgery were observed to increase as compared with the control group. CONCLUSIONS: The use of QLB for postoperative analgesia after cesarean section, particularly in the relief of acute postoperative pain, had been proven to significantly decrease the VAS score and morphine consumption within the first 24 hours after surgery. However, further studies are needed to determine its impact on managing chronic postoperative pain.

A clinical protocol for the effect of acupuncture combined with qianliean suppository on inflammatory factors in patients with chronic prostatitis.

INTRODUCTION: Chronic prostatitis (CP) is a common genitourinary disorder in adult men. It has a high incidence, a complex disease, and a lingering course, which seriously affects the quality of life of patients. For the treatment of CP, the currently available treatment methods are limited and patients are not satisfied with the treatment results. Therefore, more effective treatment options need to be further explored. METHODS: The study is a single-blind, parallel-group, randomized controlled clinical trial consisting of a 4-to-6-week treatment period and a 6-month follow-up period. Included participants will be randomized into three groups and given a treatment regimen of acupuncture, qianliean suppository, respectively. Patients in each group will be treated for 1 month as a course of treatment. The clinical efficacy and changes in inflammatory factor levels in each group will be assessed at the end of treatment. DISCUSSION: The trial aims to promote a more effective, standardized, and efficacious treatment protocol for CP in the clinical setting.
