AbstractPositioning of patients with cervical spinal lesions under general anesthesia may lead to serious neurological complications. The authors attempted awake pronation in eighteen patients to minimize the risks. In all patients, cervical instability or cervical spinal cord compression was diagnosed, and posterior fusion or laminoplasty under general anesthesia was planned. Naso-tracheal intubation was performed by broncho-fiberoptic scope under topical anesthesia and light sedation. After tracheal intubation, pronation was completed while patients were still awake. Twelve patients could change their position almost by themselves, and needed only a little assistance of the medical staff. After the patients settled in appropriate position, general anesthesia was induced. Neurological status was assessed before and after the intubation, and just before the induction of general anesthesia, to prove the absence of complications. Operations were accomplished without major troubles in all patients. During post anesthetic interviews, eight patients had memory of the positioning, but none of them had any complaints about the procedure. Awake pronation may be useful to minimize the risk of neurological complications related to positioning of surgical patients, and also need less assistance by medical staff.
