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.

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
Rapid inhalation induction with 7% sevoflurane combined with intravenous midazolam.
To identify an improved rapid inhalation induction (RII) technique by investigating hemodynamics and heart rate variability of induction with midazolam and RII with 7% sevoflurane in comparison with RII alone. ⋯ The addition of intravenous midazolam 0.1 mg/kg provides more stable hemodynamics, cardiac autonomic nervous system activity, and patient satisfaction in RII with 7% sevoflurane.

Postoperative nausea and vomiting after total intravenous anesthesia with propofol and remifentanil or alfentanil: how important is the opioid?
To compare the frequency and duration of postoperative nausea and vomiting (PONV) following total intravenous anesthesia (TIVA) with propofol and either remifentanil or alfentanil in outpatients undergoing arthroscopic surgery of the extremities. ⋯ When propofol-based TIVA is used for arthroscopic surgery, short-acting opioids do not significantly affect the risk of PONV.
