Randomized Controlled TrialInsertion length and resistance during advancing of epidural catheter.
The migration of an epidural catheter into the intravascular and subarachnoid spaces sometimes occurs. This study was designed to investigate where the resistance was felt during the advancing of the catheter into the epidural space and whether the length of catheter advanced in the epidural space affected the incidence of catheter migration. ⋯ At approximately 2.5 cm in the epidural space, advancing an epidural catheter causes resistance. Further advancing past this point may cause migration of the catheter into the vessels, or the coiling of the catheter.

Randomized Controlled TrialEffect of different anesthetic agents on oculocardiac reflex in pediatric strabismus surgery.
The oculocardiac reflex (OCR) occurs frequently during pediatric strabismus surgery. The aim of this study was to assess the effects of various anesthetic regimens on the incidence of OCR during the surgery. ⋯ Propofol or remifentanil anesthesia was associated with a higher incidence of OCR during pediatric strabismus surgery than sevoflurane and desflurane anesthesia, when either ketamine or midazolam was used as an induction agent.

Randomized Controlled TrialAn individualized recruitment maneuver for mechanically ventilated patients after cardiac surgery.
The recruitment maneuver (RM) has been shown to improve oxygenation for post-cardiopulmonary bypass (CPB) patients; however, sustained inflation of the lung gives rise to hypotension. The primary goal of our study was to evaluate the safety and efficacy of our proposed RM, defined on the basis of dynamic lung compliance (Cdyn). ⋯ The present study indicates that the individualized RM resulted in minimum changes of hemodynamics and brought about improvement in oxygenation and lung compliance.

Randomized Controlled TrialEffect of landiolol hydrochloride on suxamethonium-induced neuromuscular block.
The aim of this study was to examine the effect of landiolol hydrochloride, an ultrashort-acting beta(1)-blocker, on suxamethonium-induced neuromuscular block. ⋯ Landiolol delayed recovery from suxamethonium-induced paralysis. However, the interaction between the drugs seemed to be small in the clinical setting.

Randomized Controlled TrialLow dose of fentanyl reduces predicted effect-site concentration of propofol for flexible laryngeal mask airway insertion.
In contrast to reports on the classical laryngeal mask airway (classical LMA; CLMA), no report has calculated the 50% and 95% effect-site concentrations (EC(50) and EC(95), respectively) of propofol required for flexible LMA (FLMA) insertion. This study was designed to determine the EC(50) and EC(95) of propofol for FLMA insertion, using probit analysis, and to investigate whether supplemental 0.25 microg x kg(-1) fentanyl decreased these concentrations. ⋯ The propofol EC(50) for FLMA insertion was decreased by supplemental 0.25 microg x kg(-1) fentanyl without BIS, hemodynamic, or respiratory depression.
