Comparative Evaluation of Ambu AuraGain, LarySeal Pro and I-gel in Pediatric Airway Management for Day-Case Surgery Under Controlled Ventilation

This study aims to compare the Ambu AuraGain, LarySeal Pro LMA, and i-gel regarding their insertion characteristics, ventilation efficacy, risk of gastric insufflation, fiberoptic view quality, intraoperative and postoperative airway-related complications, and hemodynamic stability.165 consecutive pediatric patients aged 2-9 years, weighing 10-30 kg, American Society of Anesthesiologists (ASA) physical status I or II, and scheduled for elective day-case surgery suitable for supraglottic airway device (SGAD) use.Patients will be randomly assigned (n= 55 per group) using a computer-generated random number sequence (www.random.org) to one of three groups: * Group I: Ambu® AuraGain TM (Ambu Ltd Xiang Yu Xiamen, Fujian, China) * Group II: LarySeal Pro® LMA (Flexicare Medical Limited, Cynon Valley Business Park, Mountain Ash, UK).Patients will receive oral midazolam before anesthesia, followed by standard monitoring, induction with sevoflurane, fentanyl, and atracurium, and insertion of an appropriately sized SGAD by experienced anesthesiologists. Ventilation quality, oropharyngeal leak pressure (OLP), peak airway pressure (Ppeak), fiberoptic glottic view, and gastric insufflation by ultrasound will be assessed. Anesthesia will be maintained with controlled ventilation and cuff pressure adjusted to 60 cmH₂O. At the end, neuromuscular blockade will be reversed, devices removed upon awakening, and patients observed for complications such as laryngospasm, Outcome parameter (s): * Oropharyngeal Leak Pressure (OLP). * Demographic and Clinical Data. * Hemodynamics. * Insertion Data. * Peak Airway Pressure (Ppeak). * Fiberoptic Glottic View Assessment. * Ultrasound Assessment of Gastric Insufflation. * Perioperative Complications.bronchospasm, or sore throat. * Group III: I-gelTM (Intersurgical Ltd, Berkshire, RG41 2RZ, UK).

Sevoflurane Versus Propofol for Laryngeal Mask Airway Placement in Children Undergoing Surgery

The goal of this clinical trial is to compare two commonly used anesthetic medicines, sevoflurane and propofol, for inserting a laryngeal mask airway (LMA) in children undergoing minor elective surgery. A laryngeal mask airway is a device placed in the throat to help children breathe safely during anesthesia. The main questions this study aims to answer are: * Does sevoflurane produce a faster onset of anesthesia than propofol? * Is there a difference between sevoflurane and propofol in the time required to achieve jaw relaxation for LMA insertion? * Is there a difference between the two medicines in the time required for successful LMA insertion? The researchers hypothesize that children receiving sevoflurane will have a shorter induction time than those receiving propofol. A total of 170 children aged 4 to 12 years who are undergoing minor surgical procedures below the umbilicus will participate in the study. Participants will be randomly assigned to receive either intravenous propofol or inhaled sevoflurane for induction of anesthesia. During the procedure, the anesthesia team will measure the time taken to lose consciousness, the time required to achieve adequate jaw relaxation, and the time needed for successful insertion of the laryngeal mask airway. These measurements will help determine which anesthetic agent provides better conditions for LMA insertion in children.

LITES Task Order 0005 Prehospital Airway Control Trial (PACT)

The Prehospital Airway Control Trial (PACT) is a proposed 5 year, open label, multi-center, stepped-wedge randomized trial comparing airway management strategies of prehospital trauma patients. The initial airway attempt will be randomized to either usual care (control) or a supraglottic airway management approach (intervention). The primary outcome will be 24 hour survival, with secondary outcomes to include survival to hospital discharge, expected clinical adverse events, airway management performance, ICU length of stay, ventilator days, incidence of ARDS, and incidence of ventilator associated pneumonia. Subjects will be enrolled across approximately 17 prehospital agencies at select LITES Network sites and will enroll a total of 2,009 subjects.

Evaluation of SaCo VLMA for General Anesthesia for Laparoscopic Procedures

Evaluation of new supraglottic device SaCo VLMA for laparoscopic procedures under general anesthesia in comparison with other airway management methods including other supraglottic devices. The parameters noted will be: demographic data, time for placement of SGA counted from moment of grabbing device by operator to correct placement, subjective evaluation of ease of insertion of SGA in 5 step Borg scale, peak pressure, lung compliance, achieved tidal volume before creating pneumoperitoneum, after creating pneumoperitoneum, visualization of glottis on monitor of camera or fiberoptic scope.

Brain-injured Patients Extubation Readiness Study

The BIPER study is a stepped wedge cluster randomised clinical trial aiming to decrease extubation failure in critically-ill brain-injured patients with residual impaired consciousness using a simple clinical score.
