Randomized Controlled Trial Comparative StudyThe effect of alfentanil versus ketamine on the intubation condition and hemodynamics with low-dose rocuronium in children.
We investigated the effect of alfentanil and ketamine on the intubation condition and hemodynamic parameters during propofol anesthesia with low-dose rocuronium in children. ⋯ This study showed that both ketamine 0.5 mg/kg and alfentanil 20 μg/kg provided adequate intubation condition during propofol induction with low-dose rocuronium in children. The mean arterial pressure and heart rate were higher in the ketamine group after propofol injection but they remained within the normal limit in both groups throughout the study period.

Randomized Controlled TrialEffects of pretreatment with a small dose of dexmedetomidine on sufentanil-induced cough during anesthetic induction.
We aimed to investigate the effects of pretreatment with a small dose of dexmedetomidine on the cough caused by sufentanil during anesthetic induction. ⋯ Dexmedetomidine at 0.10, 0.25, and 0.50 μg/kg significantly reduced the incidence of sufentanil-induced cough during anesthetic induction, with the effect being most marked for 0.10 μg/kg dexmedetomidine.

Randomized Controlled Trial Comparative StudyComparison of effects of propofol and ketamine-propofol mixture (ketofol) on laryngeal mask airway insertion conditions and hemodynamics in elderly patients: a randomized, prospective, double-blind trial.
The objective of this study was to compare the effects of ketamine-propofol mixture (ketofol) and propofol on ProSeal laryngeal mask airway (PLMA) insertion conditions and hemodynamics in elderly patients. ⋯ The same PLMA insertion conditions were found with ketofol and propofol. The number of patients in need of ephedrine and the total ephedrine dose were lower and apnea duration was increased in the ketofol group.

Randomized Controlled TrialHyperventilation accelerates rise in arterial blood concentrations of sevoflurane in gynecologic patients.
We investigated whether ventilation volumes affected arterial blood sevoflurane concentration (A (sev)) and its uptake into the body during general anesthesia. ⋯ Hyperventilation accelerated the rate of A (sev) increase immediately after sevoflurane administration, which was time dependent with respect to different alveolar ventilation levels.

Randomized Controlled TrialThe parasacral sciatic nerve block does not induce anesthesia of the obturator nerve.
The ability of the parasacral sciatic nerve block (PSNB) to induce anesthesia of the obturator nerve remains controversial. Our objective was to evaluate the anesthesia of the obturator nerve after a PSNB. ⋯ This clinical study demonstrated that the PSNB is an unreliable means of inducing anesthesia of the obturator nerve and emphasizes the need to block this nerve separately to induce adequate analgesia during knee surgery.
