Randomized Controlled Trial Comparative Study
A Comparison of the Effectiveness of the McCoy Laryngoscope and the C-MAC D-Blade Video Laryngoscope in Obese Patients.
Background and Objective: Obesity is associated with difficult or failed intubation attempts, making general anesthesia challenging for anesthesiologists to perform. The purpose of this study was to evaluate and compare the efficacy of a McCoy laryngoscope and a C-MAC D-blade video laryngoscope for intubation in obese patients with a body mass index (BMI) ≥ 35 kg/m2. Methods: In total, 104 patients were randomly assigned to be intubated with a McCoy (McCoy group) or C-MAC D-blade video laryngoscope (C-MAC group). ⋯ The proportion of patients who required an increase in lifting force during laryngoscopy was higher in the McCoy group than in the C-MAC group, which may explain the difference in MAP between the groups. Conclusions: Both the McCoy laryngoscope and the C-MAC D-blade video laryngoscope were useful during the intubation of obese patients. The C-MAC D-blade video laryngoscope might be more useful for obese patients in terms of hemodynamic stability.

Randomized Controlled Trial Comparative Study
Remimazolam to prevent hemodynamic instability during catheter ablation under general anesthesia: a randomized controlled trial.
Maintaining hemodynamic stability during cardiac ablation under general anesthesia is challenging. Remimazolam, a novel ultrashort-acting benzodiazepine, is characterized by maintaining comparatively stable blood pressure and does not influence the cardiac conduction system, which renders it a reasonable choice for general anesthesia for cardiac ablation. We aimed to evaluate whether remimazolam is associated with a decreased incidence of intraoperative hypotension compared with desflurane. ⋯ ClinicalTrials.gov (NCT05486377); first submitted 1 August 2022.

Randomized Controlled Trial Comparative Study
Impact of spinal versus general anaesthesia on perioperative obstructive sleep apnoea severity in patients undergoing hip arthroplasty: a post hoc analysis of two randomised controlled trials.
Recommendations suggest favouring regional over general anaesthesia to reduce impact on postoperative sleep apnoea severity, but there is currently no evidence to support this. We compared the impact of general vs spinal anaesthesia on postoperative sleep apnoea severity and assessed the evolution of sleep apnoea severity up to the third postoperative night. ⋯ NCT02717780 and NCT02566226.

Randomized Controlled TrialThe effect on perioperative anxiety and emergence delirium of the child or parent's preference for parental accompaniment during anesthesia induction in children undergoing adenotonsillectomy surgery.
Pediatric emergence delirium (ED) occurs in the early postoperative period and is defined as a complex psychiatric disorder. Non-pharmacological methods of treatment, such as perioperative parental presence, have been the focus of many studies, but the impact on preventing ED of which parent accompanies the child during anesthesia induction has not been identified as yet. Therefore, the aim of this study was to determine whether the selection made by children undergoing adenotonsillectomy of which parent will accompany them during anesthesia induction has the effect of reducing postoperative delirium scores and incidence compared to selections made by the parents. ⋯ The incidence or severity of ED did not decrease significantly even though lower anxiety scores were obtained during anesthesia induction in children who were allowed to make the decision of accompanying parent. Based on these findings, it can be concluded that postoperative delirium is a more complicated process that can be affected by many other variables rather than just the parent-child general interaction.

Randomized Controlled Trial
One-lung ventilation with fixed and variable tidal volumes on oxygenation and pulmonary outcomes: A randomized trial.
Test the hypothesis that one-lung ventilation with variable tidal volume improves intraoperative oxygenation and reduces postoperative pulmonary complications after lung resection. ⋯ One-lung ventilation with variable tidal volume does not meaningfully improve intraoperative oxygenation, and does not reduce postoperative pulmonary complications.
