Randomized Controlled Trial Clinical TrialAbsence of explicit and implicit memory in unconscious patients using a TCI of propofol.
Episodes of implicit memory have been described during propofol anaesthesia. It remains unclear whether implicit memory is caused by short periods of awareness or occurs in an unconscious subject. ⋯ In our group of young ASA I/II patients, in the absence of any noxious stimulus, no implicit or explicit memory was found when the calculated concentration of propofol using a Diprifusor was maintained at the level associated with LOC.

Randomized Controlled Trial Clinical TrialEMLA does not permit pain-free retrobulbar injection.
Retrobulbar injection can be associated with significant pain, due to both needle insertion and deposition of the local anaesthetic solution. The local anaesthetic cream EMLA (eutectic mixture of local anaesthetics) which contains a mixture of lignocaine and prilocaine has been shown to reduce the pain associated with skin puncture. The efficacy of EMLA in alleviating the pain of retrobulbar injection for cataract surgery was assessed in this study. ⋯ EMLA does not permit pain-free retrobulbar injection.

Randomized Controlled Trial Comparative Study Clinical TrialResistive load of laryngeal mask airway and ProSeal laryngeal mask airway in mechanically ventilated patients.
The ProSeal Laryngeal Mask Airway (PLMA) ventilation tube is narrower and shorter than the standard Laryngeal Mask Airway (LMA) and is without the vertical bars at the end of the tube. In this randomized, crossover study, PLMA and LMA resistances were compared. ⋯ The standard LMA offers a lower resistive load than the PLMA. Moreover, the fitting between the laryngeal masks and the larynx, as fiberoptically evaluated, plays a major role in determining the resistive properties of these devices.

Randomized Controlled Trial Clinical TrialKetamine reduces swallowing-evoked pain after paediatric tonsillectomy.
Ketamine efficacy as an analgesic adjuvant has been studied in several clinical settings with conflicting results. The aim of this study was to investigate the effect of ketamine on spontaneous and swallowing-evoked pain after tonsillectomy. ⋯ Premedication with a small dose of ketamine reduces swallowing-evoked pain after tonsillectomy in children who received an analgesic regimen combining an opioid and a NSAID.

Randomized Controlled Trial Comparative Study Clinical TrialRocuronium combined with i.v. lidocaine for rapid tracheal intubation.
Rocuronium (ORG 9426) has been shown to have an onset of action more rapid than other nondepolarizing neuromuscular blocking agents and to provide intubating conditions similar to those of succinylcholine 60-90 s after administration. We compared the intubating conditions and hemodynamic changes after the administration of rocuronium 0.6 mg kg(-1) and lidocaine 1.5 mg kg(-1) with rocuronium alone and succinylcholine 60 and 90 s after administration. ⋯ The combination of lidocaine (1.5 mg kg(-1)) and low-dose rocuronium (0.6 mg kg(-1)) along with propofol is clinically equivalent to succinylcholine, improves intubating conditions in 60 s and effectively blocks increases in heart rate after intubation.
