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 Comparative StudyNon-inferiority randomized controlled trial comparing CricOid pressure and para-laryngeal pressure in parturients undergoing cesarean delivery: NiCOP trial.
Cricoid pressure has been surrounded with controversies regarding its effectiveness. Application of ultrasound-guided para-laryngeal (PL) force has been shown to occlude the esophagus effectively compared with cricoid pressure (CP) in awake patients. We hypothesized that there would be no meaningful difference in the change in antero-posterior esophageal diameter from with application of cricoid or para-laryngeal pressure in parturients undergoing cesarean delivery under general anesthesia. ⋯ Para-laryngeal pressure was non-inferior to CP in occluding the esophagus in parturients undergoing cesarean delivery under general anesthesia and furthermore, no significant deterioration in intubation parameters was seen.

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.

Processed electroencephalography-guided general anesthesia and norepinephrine requirements: A randomized trial in patients having vascular surgery.
Processed electroencephalography (pEEG) may help clinicians optimize depth of general anesthesia. Avoiding excessive depth of anesthesia may reduce intraoperative hypotension and the need for vasopressors. We tested the hypothesis that pEEG-guided - compared to non-pEEG-guided - general anesthesia reduces the amount of norepinephrine needed to keep intraoperative mean arterial pressure above 65 mmHg in patients having vascular surgery. ⋯ pEEG-guided - compared to non-pEEG-guided - general anesthesia reduced the amount of norepinephrine needed to keep mean arterial pressure above 65 mmHg by about a third in patients having vascular surgery. Whether reduced intraoperative norepinephrine requirements resulting from pEEG-guided general anesthesia translate into improved patient-centered outcomes remains to be determined in larger trials.

Randomized Controlled Trial
Safety and feasibility of early drinking water after general anesthesia recovery in patients undergoing daytime surgery.
Patients who are recovering from general anesthesia commonly exhibit symptoms such as dry lips, throat irritation, and thirst, prompting a desire to drink water in the post-anesthesia care unit (PACU). In this study, we aimed to evaluate the therapeutic effects and any potential complications of administering varying quantities of water to such patients. The primary objectives are to assess the safety and feasibility of early water intake after general anesthesia, specifically in the context of daytime surgery. ⋯ Non-gastrointestinal surgical patients who passed pre-drinking water assessments post GA(general anesthesia)recovery could safely ingest moderate amounts of water in the PACU. Early water intake is both safe and feasible, effectively fostering swift postoperative recovery.
