Manoeuvres performed to facilitate fibreoptic orotracheal intubation under general anesthesia. Could be any of them considered as more effective?

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.
