Randomized Controlled Trial
Optimal target concentration of remifentanil during cataract surgery with monitored anesthesia care.
To determine the effect-site target concentration (C(et)) of remifentanil that provides optimal conditions for patients and operators during cataract surgery during monitored anesthesia care using a target controlled infusion (TCI) of propofol and remifentanil. ⋯ C(et) values of remifentanil and propofol of one ng/mL and one μg/mL, respectively, appear to provide optimal conditions for patients and operators during cataract surgery using monitored anesthesia care with TCI.

Randomized Controlled Trial
Effects of propofol on the minimum alveolar concentration of sevoflurane for immobility at skin incision in adult patients.
To determine the effect of propofol on skin incision at target plasma concentrations of one to 6 μg/mL on the minimum alveolar concentration (MAC) of sevoflurane. ⋯ Propofol decreases the MAC of sevoflurane in a concentration-dependent manner in adult patients.

Randomized Controlled Trial Comparative Study
Does lidocaine more effectively prevent pain upon induction with propofol or etomidate when given preemptively than when mixed with the drug?
To compare the efficacy of 2% lidocaine "timing" on alleviation of pain upon induction using propofol or etomidate. ⋯ Alleviation and intensity of post-injection pain were not significantly influenced by the "timing" of administration of lidocaine 80 mg or by the specific induction drug. Pre-lidocaine and "simultaneous" lidocaine with either propofol or etomidate prevented severe pain in 95% of patients.

Randomized Controlled Trial
Effects of high intraoperative inspired oxygen on postoperative nausea and vomiting in gynecologic laparoscopic surgery.
To assess the efficacy of intraoperative inspired oxygen fractions (FIO(2)) of 0.8 and 0.5 when compared with standard FIO(2) of 0.3 in the prevention of postoperative nausea and vomiting (PONV). ⋯ High intraoperative FIO(2) of 0.8 and FIO(2) of 0.5 do not prevent PONV in patients without antiemetic prophylaxis. An intraoperative FIO(2) of 0.8 has a beneficial effect on early vomiting only.
