Abstract:
Objective To evaluate the efficacy of T-joint endoscopy mask for fiberoptic bronchoscopy (FOB)-guided awake nasotracheal intubation in patients with cervical spinal cord injury.Methods Forty patients of both sexes aged 21-64 yr with fracture of cervical spine complicated by spinal cord injury scheduled for anterior decompression and interbody fusion under general anesthesia were randomly divided into 2 groups according to the technique for awake nasotracheal intubation (n =20 each):group nasal catheter and group T-joint endoscopy mask.Topical anesthesia of nasal cavity,pharynx,larynx and trachea with 2％ lidocaine was conducted and then remifentanil was continuously infused at 0.05-0.15 μg· kg-1 · min-1 in both groups.The incidence of hypoxemia and intubation time were recorded.Arterial blood samples were obtained for determination of PaO2 and PaCO2 before topical anesthesia (baseline),immediately before and 1 min after placement of FOB and immediately after nasotracheal intubation was accomplished.Results The incidence of hypoxemia was significantly lower in group Tjoint endoscopy mask (0) than in group nasal catheter (25％) (P ＜ 0.05).The PaO2 during nasotracheal intubation was significantly higher in group T-joint endoscopy mask than in group nasal catheter (P ＜ 0.05).There was no significant difference in PaCO2 and intubation time between the 2 groups (P ＞ 0.05).Conclusion T-joint endoscopy mask facilitates awake nasotracheal intubation without affecting oxygen inhalation in patients with cervical spinal cord injuries.
