Randomized Controlled Trial Comparative Study
Comparison of the GlideScope video laryngoscope vs. the intubating laryngeal mask for females with normal airways.
In this randomized clinical study, we compared the intubation success rates of the intubating laryngeal mask airway with the GlideScope in patients with normal airways. The primary hypothesis was that the intubating laryngeal mask airway was equally effective as the GlideScope in terms of successful intubation times. ⋯ The GlideScope improved intubation time and difficulty score for tracheal intubation when compared with the intubating laryngeal mask airway in our patients. Blind intubation through the intubating laryngeal mask airway offers no advantages over the GlideScope in patients with normal airways. Despite its limitations, the intubating laryngeal mask airway is a valuable adjunct, especially in cases of difficult airway management when it can provide ventilation in between intubation attempts.

Randomized Controlled Trial Comparative Study
Preoperative oral dextromethorphan vs. clonidine to prevent tourniquet-induced cardiovascular responses in orthopaedic patients under general anaesthesia.
Preoperative oral dextromethorphan and intravenous clonidine attenuate arterial pressure and heart rate increases during tourniquet inflation under general anaesthesia. The effect of preoperative oral clonidine on these variables has not been investigated. ⋯ Preoperative oral clonidine 3 microg kg(-1) significantly prevented tourniquet-induced systemic arterial pressure increase in patients under general anaesthesia better than oral dextromethorphan.

Recovery of older patients undergoing ambulatory anaesthesia with isoflurane or sevoflurane.
Delayed recovery of cognitive function is a well-recognized phenomenon in older patients. The potential for the volatile anaesthetic used to contribute to alterations in postoperative cognitive function in older patients following minor surgical procedures has not been determined. We compared emergence from isoflurane and sevoflurane anaesthesia in older surgical patients undergoing urological procedures of short duration. ⋯ Isoflurane and sevoflurane anaesthesia resulted in similar clinical and neurocognitive recovery profiles in older patients undergoing ambulatory surgical procedures of short duration.

PercuTwist: a new alternative to Griggs and Ciaglia's techniques.
Tracheostomy is one of the most common procedures in intensive care units worldwide. In this study we aimed to compare three different tracheostomy techniques with respect to duration of procedure and complications. ⋯ Percutaneous tracheostomy techniques have their own advantages and complications. PercuTwist, a new controlled rotating dilatation method, was associated with minimal complications, appears to be easy to perform and a practical alternative to percutaneous dilatational tracheostomy and guide-wire dilating forceps techniques.

Randomized Controlled Trial
Does dexmedetomidine reduce the injection pain due to propofol and rocuronium?
This prospective, double-blind, randomized, placebo-controlled study was designed to determine the efficacy of dexmedetomidine compared with lidocaine in reducing the pain of propofol and rocuronium injection pain. ⋯ Pretreatment with dexmedetomidine is not effective in reducing injection pain of propofol, but may attenuate the hand withdrawal associated to rocuronium, as lidocaine does.
