While laryngeal mask is widely used for laparoscopic interventions in some countries, concerns exist regarding pulmonary aspiration and inadequate ventilation. We compared the LM-Supreme™ (LM-S) with the endotracheal tube (ETT) for laparoscopic gynecological interventions in terms of ventilation parameters and gastric distention. This prospective randomized and double-blind study. The patients were divided into two groups: ETT (n = 50) and LM-S group (n = 50). All patients in the LM-S and ETT groups recieved total intravenous general anaesthesia and standard ventilation protocols. Ventilation parameters (airway peak pressure, mean airway pressure, end-tidal carbon dioxide, total volume, oropharyngeal leak pressure) and perioperative laryngopharyngeal morbidity were recorded before peritoneal insufflation, during and after the peroperative period. The mean airway pressure values in the ETT group 2 min after airway device insertion were significantly higher. The gastric distension after the laparoscope entered the abdomen in the LM-S group was found to be significantly lower. In the first hour postoperative sore throat, disphonia and dysphagia were statistically significantly higher in the ETT group. In our study we concluded that LM-S provides reliable endotracheal intubation in ASA I & II patients undergoing laparoscopic gynecological surgery under positive pressure ventilation.ClinicalTrials.gov ID NCT02127632.

Objective: Rapid sequence intubation (RSI) involves the administration of induction agents and neuromuscular blockers before endotracheal intubation (ETI). However, RSI seems to be underutilized outside emergency departments (ED). We compared RSI adoption rates and ETI outcomes outside and within EDs and investigated whether RSI adoption affected ETI outcomes outside EDs.

Despite these advantages, ciprofol's clinical research is still emerging. This study compares the median effective dose (ED) and adverse reactions of ciprofol and propofol, in conjunction with sufentanil, for suppressing cardiovascular responses during tracheal intubation.

Background: Airway management is a critical component of the care of patients experiencing cardiac arrest, but data from randomized trials on the use of video vs direct laryngoscopy for intubation in the setting of cardiac arrest are limited. Current AHA guidelines recommend placement of an endotracheal tube either during CPR or shortly after return of spontaneous circulation but do not provide guidance around intubation methods, including the choice of laryngoscope.
Research Question: Does use of video laryngoscopy improve the incidence of successful intubation on the first attempt, compared to use of direct laryngoscopy, among adults undergoing tracheal intubation after experiencing cardiac arrest?
Study Design And Methods: This secondary analysis of the Direct versus Video Laryngoscope (DEVICE) trial compared video laryngoscopy versus direct laryngoscopy in the subgroup of patients who were intubated following cardiac arrest.

Background: Colistin, a last-resort antibiotic for treating multidrug-resistant Gram-negative bacterial infections, has increased resistance as a result of the emergence of the gene. The 1gene, which confers colistin resistance, is often carried on plasmids, facilitating its spread by horizontal gene transfer among bacterial populations. The rising prevalence of 1mediated resistance poses significant challenges for infection control and treatment efficacy.

Mediastinal mass syndrome represents a major threat to respiratory and cardiovascular integrity, with difficult evidence-based risk stratification for interdisciplinary management. We conducted a narrative review concerning risk stratification and difficult airway management of patients presenting with a large mediastinal mass. This is supplemented by a case report illustrating our individual approach for a patient presenting with a subtotal tracheal stenosis due to a large cyst of the thyroid gland.
