BackgroundPostoperative sore throat and other airway morbidities are common and troublesome after endotracheal tube intubation general anesthesia (ETGA). We propose lidocaine as endotracheal tube (ETT) cuff inflation media to reduce the postintubation-related emergence phenomenon.MethodsWe searched PubMed, EMBASE, and Cochrane databases systematically for randomized controlled trials (RCTs) that have investigated the outcome of intracuff lidocaine versus air or saline in patients receiving ETGA. Using a random-effects model, we conducted a meta-analysis to assess the relative risks (RRs) and mean difference (MD) of the incidence and intensity of relevant adverse outcomes.ResultsWe reviewed nineteen trials, which comprised 1566 patients. The incidence of early- and late-phase postoperative sore throat (POST), coughing, agitation, hoarseness, and dysphonia decreased significantly in lidocaine groups, with RRs of 0.46 (95% confidence interval [CI]: 0.31 to 0.68), 0.41 (95% CI: 0.25 to 0.66), 0.43 (95% CI: 0.31 to 0.62), 0.37 (95% CI: 0.25 to 0.55), 0.43 (95% CI: 0.29 to 0.63), and 0.19 (95% CI: 0.08 to 0.5), respectively, when compared with the control groups. The severity of POST also reduced significantly (mean difference [MD] -16.43 mm, 95% CI: -21.48 to -11.38) at 1 h and (MD -10.22 mm, 95% CI: -13.5 to -6.94) at 24 h. Both alkalinized and non-alkalinized lidocaine in the subgroup analyses showed significant benefits in emergence phenomena prevention compared with the control.ConclusionOur results indicate that both alkalinized and non-alkalinized intracuff lidocaine may prevent and alleviate POST and postintubation-related emergence phenomena.

Summary Purpose:  People with epilepsy are more likely than healthy people to experience comorbidities and complications in various medical situations. However, the prevalence of postoperative complications, mortality, and use of medical resources in surgical patients with epilepsy has not been studied. The purpose of this study is to examine whether epilepsy is an independent risk factor for postoperative adverse outcomes of patients receiving major surgery. Methods:  Retrospective cohort study using the National Health Insurance Research Database to identify patients with epilepsy who underwent major surgery in Taiwan between the years 2004 and 2007. For each case, four age‐ and sex‐matched participants without epilepsy were included. Preoperative comorbidities in the 24 months before surgery were identified. Eight major postoperative complications, overall 30‐day mortality, and in‐hospital utilization of medical resources (including length of hospital stay, percentage of postoperative intensive care unit admissions, and in‐hospital medical expenditures) served as the major outcome measurements. Comorbidities, status of receiving renal dialysis, teaching hospital status, types of surgery, and patients living in urban or rural areas were adjusted by multivariate logistic regression. Key Findings:  A total of 13,103 participants with epilepsy and 52,412 without were included. Patients with epilepsy have significantly more preoperative comorbidities and demonstrated more risks of any postoperative complications (odds ratio 2.02, 95% confidence interval 1.90–2.14). Consumption of in‐hospital medical resources was also significantly higher in patients with epilepsy, but no significant differences in postoperative mortality rates between the two groups were noted. Significance:  Stroke was identified as the most significant postoperative complication for surgical patients with epilepsy. Patients, especially those with previous hospitalization or emergency visits due to the disease, confronted significantly higher postoperative complication rates, and consumed more in‐hospital medical resources without differences in overall mortality rates. Further revision of health care standards to provide early recognition of postoperative complications and better management for surgical patients with epilepsy is needed.

Our results indicate that the incidence of POST can be significantly reduced by prophylactic BH topical application to the oral cavity or airway devices. Further RCTs are required to overcome the limitations of heterogeneity and to determine the optimal dosage and application of BH for managing POST.

Tracheal bronchus is a congenital anatomical variant of patients with accessory bronchus in the right upper lobe deriving directly from the supracarinal trachea. Pre-operative consultation with the anesthesiologist is important for patient safety and can avoid adverse effects induced by endotracheal intubation. In this report, we described a case of tracheal bronchus in which general anesthesia was performed for video-assisted thoracoscopic surgery. We discussed some of the issues surrounding to complications in tracheal bronchus.
