Randomized Controlled Trial Clinical Trial
Urapidil does not prevent postanesthetic shivering: a dose-ranging study.
To investigate the effect of 0.2 mg x kg(-1), 0.3 mg x kg(-1) and 0.4 mg x kg(-1) urapidil on the incidence and severity of postanesthetic shivering. ⋯ Urapidil showed no beneficial effect on shivering in any of the doses evaluated, whereas prophylactic administration of clonidine was effective in preventing postanesthetic shivering.

Randomized Controlled Trial Clinical Trial
New landmarks improve the positioning of the left Broncho-Cath double-lumen tube-comparison with the classic technique.
To compare a new technique (NT) for positioning the left modified Broncho-Cath double-lumen tube (LM- DLT) by fibreoptic bronchoscopy (FOB) to the classic technique (CT). ⋯ Using this new technique, the LM-DLT is inserted deeper in the left mainstem bronchus. This new landmark augments the range of movement that can be tolerated without requiring repositioning of the LM-DLT. This NT to position and to assess LM-DLT, by transparency across the wall of the tube with FOB, is better adapted to the LM-DLT and its recent modifications.

To present a stepwise training method, first critiquing laryngeal mask (LM) insertion difficulty and malpositioning, then learning how to exchange an endotracheal tube (ETT) for a LM during emergence from anesthesia. ⋯ We found it is easy to learn how to insert a LM in the presence of an oral ETT. The most serious malposition, occurring in 5% of first attempts, was insufficient insertion depth. The only other malposition we encountered, fibreoptic visualization of the epiglottis, is not likely to result in complete airway obstruction following endotracheal extubation under anesthesia.
