The aim of this study was to compare the combination of oral tramadol and midazolam to oral midazolam alone, in children undergoing adenotonsillectomy, as an oral premedication, regarding also sedation and postoperative pain relief. Sixty children selected for elective adenotonsillectomy were enrolled in this randomized, controlled prospective study. Patients were randomly allocated into two groups. Group M (n=30) received 0.5 mg.kg-1 oral midazolam and group MT (n=30) received 0.2 mg.kg-1 oral midazolam with 1 mg.kg-1 oral tramadol as a premedication 30min preoperatively. Standard general anesthesia technique was used.

Our study compared the effectiveness between two of the proposed as rescue manoeuvres to overcome difficulty, in advancing a tracheal tube, during railroading over the fibreoptic bronchoscope. A ninety degrees anti-clockwise rotation (90ΑCWR) of the tube or cricoid cartilage pressure application (CCPA) was randomly performed in eighty patients undergoing fibreoptic orotracheal intubation under general anaesthesia, in whom first attempt to railroad the tracheal tube had failed.
