In the perioperative period, the major concern related to GLP-1RA is gastric emptying delay and risk of aspiration. This meta-analysis and systematic review compared the risks and benefits of using GLP-1 agonist receptors and control in surgical and nonsurgical procedures under anesthesia or sedation. We systematically searched MEDLINE, Embase, and Cochrane for randomized controlled trials and observational studies involving patients &gt; 18 years undergoing elective surgeries or procedures. Outcomes of interest were pre-procedural gastrointestinal (GI) symptoms, residual gastric content assessed by endoscopy, pulmonary aspiration during anesthesia/sedation, perioperative glycemic control, postoperative inotropic support, nausea/vomiting (PONV), atrial fibrillation, and 30-day mortality rate. We used a random effects model, with odds ratio and mean difference computed for binary and continuous outcomes, respectively. Fourteen randomized and observational studies with 2143 adult patients undergoing elective surgeries and procedures were included. GLP-1RA resulted in increased pre-procedural GI symptoms (OR 7.66; 95% CI 3.42, 17.17; p &lt; 0.00001; I2 = 0%) and elevated residual gastric content (OR 6.08; 95% CI 2.86, 12.94; p &lt; 0.00001; I2 = 0%). GLP-1RA resulted in lower glycemic levels (MD − 0.73; 95% CI − 1.13, − 0.33; p = 0.0003; I2 = 90%) and lower rate of rescue insulin administration (OR 0.39; 95% CI 0.23, 0.68 p = 0.0009; I2 = 35%). There was no significant difference in rate of perioperative hypoglycemia (OR 0.60; 95% CI 0.29, 1.24; p = 0.17; I2 = 0%), hyperglycemia (OR 0.89; 95% CI 0.59, 1.34; p = 0.58; I2 = 38%), need for postoperative inotropic support (OR 0.57; 95% CI 0.33, 1.01; p = 0.05; I2 = 0%), atrial fibrillation (OR 1.02; 95% CI 0.52, 2.01; p = 0.95; I2 = 16%), rate of PONV (OR 1.35; 95% CI 0.82, 2.21; p = 0.24; I2 = 0%), and 30-day mortality rate (OR 0.54; 95% CI 0.14, 2.05; p = 0.25; I2 = 0%). Compared to control, pre-procedural GLP-1RA increased the rate of GI symptoms and the risk of elevated residual gastric content despite adherence to fasting guidelines. GLP-1RA improved glycemic control and decreased the rate of rescue insulin administration. There was no significant difference in the rates of perioperative hypo or hyperglycemia, postoperative inotropic support, PONV, atrial fibrillation, and 30-day mortality. • Question: What are the benefits and risks of using GLP-1RAs in patients undergoing anesthesia or sedation? • Finding: This meta-analysis demonstrates that perioperative GLP-1RAs increased the rate of GI symptoms and the risk of elevated residual gastric content, improved glycemic control, and did not change the rates of hypo or hyperglycemia, postoperative inotropic support, PONV, atrial fibrillation, and 30-day mortality. • Meaning: Despite improving glycemic control, providers must be","PeriodicalId":19764,"journal":{"name":"Perioperative Medicine","volume":"38 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141744134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reviewed the Manning et al. study, which implemented a multidisciplinary opioid reduction pathway and compared outcomes before and after pathway implementation. Outcomes included opioid use, pain scores, antiemetic use, length of stay, and readmissions. The study found reduced opioid consumption, lower antiemetic use, shorter length of stay, and similar pain scores after pathway implementation. However, the pre-post-study design has limitations in attributing causality to the pathway itself. Key confounders were not fully accounted for. The clinical significance of the small reduction in length of stay is also questionable. This commentary highlights important limitations of the Manning et al. study, including the retrospective design, potential confounding factors, small effect size, and lack of long-term outcomes. While the study provides early evidence for a multidisciplinary opioid reduction approach, further rigorous prospective research is needed to confirm the observed benefits and long-term impacts.

This study aimed to externally validate RCRI in this patient group over a 15-year period. Data linkage was used between the the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry and jurisdictional hospital admisisons data across Australia and New Zealand to identify all incident and prevalent patients on chronic KRT between 2000 and 2015 who underwent elective abdominal surgery. Chronic KRT was categorised as haemodialysis (HD), peritoneal dialysis (PD), home haemodialysis (HHD) and kidney transplant. The outcome of interest was major adverse cardiovascular event (MACE) which was defined as nonfatal myocardial infarction, nonfatal stroke, non-fatal cardiac arrest and cardiovascular mortality at 30 days. Logistic regression was used with the RCRI score included as a continuous variable to estimate discrimination by area under the receiver operating curve (AUROC). Calibration was evaluated using a calibration plot. Clinical utility was assessed using a decision curve analysis to determine the net benefit. A total of 5094 elective surgeries were undertaken, and MACE occurred in 153 individuals (3.0%). Overall, RCRI had poor discrimination in patients on chronic KRT undergoing elective surgery (AUROC 0.67), particularly in patients aged greater than 65 years (AUROC 0.591). A calibration plot showed that RCRI overestimated risk of MACE. The expected-to-observed outcome ratio was 6.0, 5.1 and 2.5 for those with RCRI scores of 1, 2 and ≥ 3, respectively. Discrimination was moderate in patients under 65 years and in kidney transplant recipients, with AUROC values of 0.740 and 0.718, respectively. Overestimation was common but less so for kidney transplant recipients. Decision curve analysis showed that there was no net benefit of using the tool in neither the overall cohort nor patients under 65 years, but a slight benefit associated with threshold probability > 5.5% in kidney transplant recipients. The RCRI tool performed poorly and overestimated risk in patients on chronic dialysis, potentially misinforming patients and clinicians about the risk of elective surgery.
