Background A high prevalence of postoperative complications is closely associated with a worse short- and long-term outcome. This current study aimed to investigate potential risk factors including albumin-to-fibrinogen ratio (AFR) for severe postoperative complications (SPCs) in surgical gastric cancer (GC) patients. Methods Elderly patients (≥65 years) with primary GC who underwent elective radical laparoscopic gastrectomy under general anesthesia were included. According to the Clavien–Dindo classification system, the severity of complications was assessed from Grade I to V and SPCs were defined as C-D Grade ≥ IIIa. The clinicopathological features, operative-associated characteristics, postoperative recovery and laboratory tests were compared between patients with or without SPCs. Receiver operating characteristic (ROC) curve analysis using Youden’s Index was established for determining the predictive value and cut-off threshold of AFR for SPCs. Binary univariate and multivariate logistic regression models were used to assess factors influencing SPCs. Results A total of 365 elderly GC patients were finally included in the analysis, of which 52 (52/365, 14.2%) patients had developed SPCs within postoperative 30 days. Preoperative AFR level predicted SPCs in surgical GC patients with an AUC of 0.841, a sensitivity of 76.36% and a specificity of 80.77%, respectively (P < 0.001). The multivariate analysis revealed that a lower AFR level (OR: 1.94, 95% CI: 1.09–3.36, P = 0.017) and an older age (OR: 1.81, 95% CI: 1.06–3.04, P = 0.023) were two independent predictive factors for SPCs in surgical GC patients. Conclusions Preoperative AFR level is a useful predictor for SPCs in elderly GC subjects after radical laparoscopic gastrectomy.
Background: This study systematically evaluated the safety and efficacy of dexmedetomidine for procedural sedation and postoperative behaviors in a pediatric population as well as whether the results met the information required to draw conclusions. Objective: To evaluate the safety and efficacy evaluation of dexmedetomidine for procedural sedation and postoperative behaviors in a pediatric population. Methods: PubMed, Cochrane library, Web of Science and Ovid MEDLINE were searched to obtain randomized controlled trials (RCTs) comparing dexmedetomidine with control medicine and comparing different doses of dexmedetomidine. Results: There were a total of 16 RCTs for a total of 3240 patients. Dexmedetomidine slowed down the heart rate (HR; mean difference: −13.27; 95% CI: −16.41 to 10.14; P < 0.001) and reduced postoperative delirium (risk ratio [RR]: 0.31; 95% CI: 0.20-0.50; P < 0.001), the number of pain patients (RR: 0.48; 95% CI: 0.30-0.75; P = 0.002), and desaturation (RR: 0.34; 95% CI: 0.13-0.89; P = 0.03) compared with the control group. The limitation was that it was difficult to determine the range of low- and high-dose dexmedetomidine. Conclusion and Relevance: Dexmedetomidine slowed down intraoperative HR within the normal range, which might reduce myocardial oxygen consumption. It reduced postoperative pain and postoperative complications: delirium and desaturation. Dexmedetomidine showed no dose-dependent increase in the procedural sedation time of pediatric patients. Clinically, dexmedetomidine can improve pediatric procedural sedation and postoperative behavior, and it can be considered as a related medicine for safety in pediatric surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
