Randomized Controlled Trial Comparative Study Clinical TrialThe use of the laryngeal mask airway as an alternative to the endotracheal tube during percutaneous dilatational tracheostomy.
To evaluate the safety and efficiency of the use of the laryngeal mask airway (LMA) during percutaneous dilatational tracheostomy under bronchoscopic guidance comparing with the ventilation via endotracheal tube (ET). ⋯ LMA is an effective and successful ventilatory device during percutaneous dilatational tracheostomy. It improves visualization of the trachea and larynx during fiberoptic-assisted percutaneous dilatational tracheostomy and prevents the difficulties associated with the use of ET such as cuff puncture, tube transection by the needle, and accidental extubation. The use of a bronchoscope and the puncture of the ET cuff cause major increases in PaCO2.

Randomized Controlled Trial Comparative Study Clinical TrialProne positioning, systemic hemodynamics, hepatic indocyanine green kinetics, and gastric intramucosal energy balance in patients with acute lung injury.
To investigate the effects of prone positioning on systemic hemodynamics, intra-abdominal pressure (IAP), plasma disappearance rate of indocyanine green (PDR(ICG)), and gastric intramucosal to arterial PCO2 difference (Pi-aCO2). ⋯ Prone positioning in mechanically ventilated patients with acute lung injury, despite a small increase in IAP, does not negatively affect the hepatic capacity to eliminate ICG and gastric intramucosal energy balance when systemic blood flow and oxygenation are improved.
