Randomized Controlled Trial Comparative Study
A comparison of intra cuff pressures in high-flow and low-flow nitrous oxide anesthesia.
To investigate intra cuff pressure changes in low-flow anesthesia (LFA) and high-flow (HFA) N2O anesthesia during moderate-duration surgical procedures. ⋯ The intra cuff pressures should be monitored carefully during LFA, since the duration to reach the maximum intra cuff pressures was shorter than that of HFA.

Randomized Controlled Trial Comparative Study
Does the use of radiofrequency ultrasonic dissector in tonsillectomy have a beneficial effect over the use of laser?
To compare the intra- and post- operative morbidities on the use of radiofrequency ultrasonic dissector (US) with the use of laser during tonsillectomy in the same patients. ⋯ The use of US in tonsillectomy showed a beneficial effect on intraoperative blood loss, duration of the operation, as well as, postoperative pain over the use of laser.
