Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study of two methods for laryngeal mask insertion].
To compare two ways of inserting laryngeal airway masks: uninflated and partially inflated to 75% of the volume, as recommended by manufacturers. ⋯ No differences were found between inflated insertion and Brain's uninflated insertion technique. We believe that inflated mask insertion might be useful when uninflated insertion proves impossible.

Randomized Controlled Trial Comparative Study Clinical Trial[Evaluation of amplified spontaneous pattern ventilation in postoperative patients. Comparison with pressure support].
Amplified spontaneous pattern (ASP) ventilation is a new method for giving partial support by reproducing, in an amplified manner, the patients' own spontaneous flow wave form, thereby optimizing patient adaptation to support. ⋯ Adaptation to support is better with ASP than with PS during postoperative weaning and causes no significant respiratory work overload.

Randomized Controlled Trial Clinical Trial[Conditions of intubation and neuromuscular block induced by mivacurium: comparison with succinylcholine].
To compare the clinical conditions for intubation and neuromuscular parameters after a high dose of mivacurium (0.25 mg/kg; 3 x SD95) administered in 30 s to those obtained after use of the usual dose of succinylcholine (1 mg/kg). ⋯ Given the moderate conditions of intubation achieved at 60 s, mivacurium can not be recommended as a relaxant in situations that require a rapid induction sequence. In elective surgery, 0.25 mg/kg of mivacurium can, however, be considered an alternative to succinylcholine.

Randomized Controlled Trial Clinical Trial[Comparative study of 3 techniques for total intravenous anesthesia: midazolam-ketamine, propofol-ketamine, and propofol-fentanyl].
To compare the characteristics of induction, maintenance and awakening for three techniques of combined total intravenous anesthesia (TIVA): propofol-ketamine, midazolam-ketamine and propofol-fentanyl. ⋯ TIVA with ketamine and propofol is comparable to the most commonly used combination of propofol and fentanyl and may be an appropriate choice when hemodynamic stability is of great importance; withdrawal 15 min before ending surgery prevents prolonged awakening. Perfusion of midazolam-ketamine is not recommendable for scheduled surgery because it induces too many hypertensive peaks. Although neither midazolam nor propofol completely prevents the psychomimetic effects of ketamine, such effects are not so severe that patients reject the anesthetic technique used.

Randomized Controlled Trial Comparative Study Clinical Trial[Efficacy of EMLA cream, effect of time and place of application].
To evaluate the anesthetic efficacy of EMLA cream for alleviating pain associated with puncture and pressure in areas where venous catheters are normally inserted. ⋯ The efficacy of EMLA cream varies demonstrably depending on type of stimulus, site of application and time since application.
