To estimate the optimal endotracheal tube (ETT) length in orotracheally intubated patients. ⋯ The optimal insertion length of the ETT for orotracheally intubated adult patients with the head placed in a neutral position is correlated with body height. The proposed formula can provide a useful guide to determine the optimal ETT tip position in most of the patients who required orotracheal intubation.

The Combitube (Tyco-Healthcare-Kendall-Sheridan, Mansfield, MA) is an easily inserted and highly efficacious device to be used as an alternative airway whenever conventional ventilation fails. The Combitube allows ventilation and oxygenation whether the device locates in the esophagus (very common) or the trachea (rare). ⋯ Contrary to the Laryngeal Mask Airway, the Combitube may help in patients with limited mouth opening. The Combitube may be of special benefit in patients with massive bleeding or regurgitation, and it minimizes the risk of aspiration.

Randomized Controlled Trial Clinical Trial
Postoperative nausea and vomiting: comparison of the effect of postoperative meperidine or morphine in gynecologic surgery patients.
To evaluate the incidence and severity of postoperative nausea and vomiting in women receiving postoperative intravenous morphine or meperidine following gynecologic surgery. ⋯ Our study demonstrates an advantage of the use of morphine rather than meperidine for pain control in the immediate postoperative period following gynecologic surgery.

Randomized Controlled Trial Clinical Trial
The quotient end-tidal/inspired concentration of sevoflurane in a low-flow system.
To investigate the effect of two different fresh gas flows on inspired and end-tidal sevoflurane concentration for a given vaporizer setting in a low-flow anesthesia system. ⋯ After 120 minutes of sevoflurane anesthesia at a vaporizer setting of 2% there is a significant difference between fresh gas flow of 1.0 and 2.0 L/min for inspired and end-tidal concentrations, but not for the ratio end-tidal/inspired.

Comparative Study
Postoperative nausea and vomiting after craniotomy for tumor surgery: a comparison between awake craniotomy and general anesthesia.
To assess the frequency of postoperative nausea and vomiting (PONV) in patients following an awake craniotomy compared to general anesthesia for tumor surgery. ⋯ The frequency of PONV during the initial recovery phase was less in patients having an awake craniotomy for tumor surgery than in patients having a similar procedure with general anesthesia.
