Clinical Trial Controlled Clinical Trial
Effects of Trendelenburg and reverse Trendelenburg postures on lung and chest wall mechanics.
To test whether the Trendelenburg ("head-down") or reverse Trendelenburg ("head-up") postures change lung and chest wall mechanical properties in a clinical condition. ⋯ The Trendelenburg posture increases the mechanical impedance of the lung to inflation, probably due to decreases in lung volume. This effect may become clinically relevant in patients predisposed with lung disease and in obese patients.

Randomized Controlled Trial Clinical Trial
The effect of laryngeal mask cuff pressure on postoperative sore throat incidence.
To study the effect of laryngeal mask airway (LMA) cuff pressure on the incidence of postoperative sore throat. ⋯ A significant increase in cuff pressure is seen during the first 60 minutes. Three minutes after insertion of the laryngeal mask, cuff pressure can significantly be reduced without any major gas leakage. Postoperative sore throat can be reduced when cuff pressure is continuously monitored and kept on low-pressure values.
