S110 Lactated Ringer’s vs Normal Saline for Acute Pancreatitis: An Updated Systematic Review and Meta-Analysis

Background: The objective of this study is to analyze the efficacy of local bupivacaine irrigation after augmentation mammoplasty for the control of postoperative pain. Methods: A systematic review and meta-analysis was conducted including all randomized controlled trials (RCTs) that compared the irrigation of bupivacaine (±ketorolac) versus normal saline or no irrigation for pain control after breast augmentation. The primary outcome was postoperative pain measured by visual analog scale. The study protocol was established a priori according to the recommendations of the Cochrane Collaboration. A bibliographical search was conducted in September 2015 in the following Cochrane Library databases: CENTRAL, MEDLINE, EMBASE, and Scielo. The strategy used for the search was ((augmentation AND (“mammoplasty”[MeSH Terms] OR “mammoplasty”)) OR ((“breast”[MeSH Terms] OR “breast”) AND augmentation)) AND ((“pain, postoperative”[MeSH Terms])). Results: Four RCTs with a total of 264 participants were included. Two trials compared bupivacaine alone versus placebo (normal saline or no irrigation) and 3 trials compared bupivacaine plus ketorolac versus placebo. The combined irrigation of bupivacaine and ketorolac showed a clinically significant reduction of pain in the first postoperative hour and on postoperative day 5. The irrigation with bupivacaine compared with placebo significantly reduced pain assessed on postoperative day 4. Conclusion: The irrigation of bupivacaine with or without ketorolac was associated with a reduction of postoperative pain compared with control groups for the first 5 postoperative days. Due to the few number of trials included, these results should be correlated further clinically.

Background: Lateral epicondylitis, or tennis elbow, is a painful degenerative disorder that commonly occurs in adults between 40 and 60 years of age. Normal saline (NS) injections have been used as placebo through a large number of randomized controlled trials (RCTs) focused on the treatment of lateral epicondylitis. Purpose: This meta-analysis of RCTs aimed to assess the therapeutic effect of NS injections on lateral epicondylitis symptoms and compare results with established minimal clinically important difference criteria. Study Design: Systematic review and meta-analysis. Methods: MEDLINE, Embase, Web of Science, and Scopus databases were searched for clinical trials reporting pain and joint function with the visual analog scale, Patient-Rated Tennis Elbow Evaluation, and Disabilities of the Arm, Shoulder and Hand in patients with lateral epicondylitis. The meta-analysis was conducted with a random effects model and generic inverse variance method. Heterogeneity was tested with the I2 statistic index. Results: A total of 15 RCTs included in this meta-analysis revealed a significant improvement in pain (mean difference, 3.61 cm [95% CI, 2.29-4.92 cm]; P < .00001; I2 = 88%; visual analog scale) and function (mean difference, 25.65 [95% CI, 13.30-37.99]; P < .0001; I2 = 82%; Patient-Rated Tennis Elbow Evaluation / Disabilities of the Arm, Shoulder and Hand) after NS injection (≥6 months). Conclusion: NS injections yielded a statistically significant and clinically meaningful improvement in pain and functional outcomes in patients with lateral epicondylitis. New research should focus on better methods to diminish the potential confounders that could lead to this effect because NS injections could mask the real effect of an active therapeutic intervention in RCT.
