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.

Randomized Controlled Trial Comparative StudyA randomized comparison of the i-gel and the ProSeal laryngeal mask airway in pediatric patients: performance and fiberoptic findings.
We compared the insertion performance of the pediatric size 1.5-3 i-gel airway device with that of the ProSeal laryngeal mask airway (PLMA) in anesthetized children in a prospective, randomized, controlled manner. ⋯ Both the pediatric i-gel and the PLMA were successfully inserted in children. The fiberoptic view was better with the i-gel than with the PLMA.

Randomized Controlled TrialEpinephrine decreases the dose of hyperbaric bupivacaine necessary for tourniquet pain blockade during spinal anesthesia for total knee replacement arthroplasty.
We quantified the dose-sparing effect of epinephrine by comparing the median effective dose (ED(50)) of intrathecal hyperbaric bupivacaine co-administered with epinephrine with the ED(50) of intrathecal hyperbaric bupivacaine alone. ⋯ Intrathecal epinephrine did not decrease the dose of intrathecal hyperbaric bupivacaine required for successful anesthesia. However, it reduced the dose required for tourniquet pain blockade.
