Randomized Controlled Trial Clinical TrialEpileptiform EEG during sevoflurane mask induction: effect of delaying the onset of hyperventilation.
Hyperventilation during sevoflurane-N2O-O2 mask induction in adults is associated with a hyperdynamic circulatory response and epileptiform electroencephalogram (EEG). We tested the hypothesis that delaying onset of hyperventilation will prevent severe (periodic) epileptiform EEG and hyperdynamic response. ⋯ Regardless of its timing, hyperventilation at a high sevoflurane concentration produced severe epileptiform EEG with a hyperdynamic response. PED tended to occur more often with immediate onset of hyperventilation.

Randomized Controlled Trial Clinical TrialRemifentanil and propofol without muscle relaxants or with different doses of rocuronium for tracheal intubation in outpatient anaesthesia.
Intubation using propofol and remifentanil without muscle relaxant is associated with a greater incidence of poor intubating conditions.

Randomized Controlled Trial Clinical TrialEsmolol cardioplegia in unstable coronary revascularisation patients. A randomised clinical trial.
Esmolol has been studied and applied to control hypertension and tachycardia during open heart surgery. Esmolol has been used on a minor scale as a single cardioplegic agent. Little information is available on esmolol as a component of blood cardioplegia. In this prospective, randomised, double-blind clinical study we investigated whether esmolol improves cardioprotection in patients scheduled for an urgent coronary operation. ⋯ Esmolol addition to blood cardioplegia did not increase the efficacy of cardioprotection in the present study setting in unstable patients during urgent coronary revascularisation.

Randomized Controlled Trial Meta Analysis Comparative Study Clinical TrialPostural post-dural puncture headache. A prospective randomised study and a meta-analysis comparing two different 0.40 mm O.D. (27 g) spinal needles.
To compare the incidence of postural post-dural puncture headache (PPDPH) after spinal anaesthesia using two different 0.40 mm O.D. (27 g) spinal needles: pencil-point needle and Quincke needle. In addition, a meta-analysis of studies comparing small bore spinal needles with regard to development of PPDPH was performed. ⋯ A pencil-point-shaped spinal needle will significantly reduce PPDPH compared with Quincke-type spinal needles, also when small bore needles (0.40 mm O.D.) are used.

Randomized Controlled Trial Clinical TrialTopical tenoxicam from pharyngeal pack reduces postoperative sore throat.
One puff of beclomethasone inhaler has been shown to reduce the incidence of sore throat following endotracheal intubation. The aim of this study was to determine the effect of a pharyngeal pack on the incidence of sore throat and whether tenoxicam-impregnated gauze pack significantly influenced the frequency of sore throat. ⋯ The intraoperative use of a tenoxicam-impregnated gauze pack is effective in reducing moderate or severe postoperative sore throat following the use of throat pack.
