RESUMO
Background@#Vocal cord polyps are commonly encountered in the otorhinolaryngology department. The risk of anesthesia is high in patients with large vocal cord polyps. Awake intubation with appropriate airway tools provides a favorable safety profile.Case: We present the case of a 60-year-old male patient who had been suffering from a large vocal cord polyp for 16 years. Electronic laryngoscopy revealed that the vocal cord polyp was approximately 1.5 cm in diameter. The polyp had a pedicle and demonstrated synchronous motion with respiratory excursion. It covered almost the entire glottic area during inspiration and moved away from the glottis during expiration. A Disposcope endoscope was used for awake tracheal intubation, and the surgery was completed successfully. @*Conclusions@#The Disposcope endoscope can be a useful option for awake orotracheal intubation in cases of anticipated difficult intubation and difficult facemask ventilation.
RESUMO
Aim To study the anti-stress depression effect of Jiaweisinisan(JWSNS)and it's mechanism of N-methyl-D-aspartate(NMDA)receptor channel in hippocampus.Methods Chronic mild unpredictable stress(CMUS)was adopted to establish the rat depres-sion model.Before and after model establishing,the sucrose consumptions and the weight of rats were detected.TTC dyeing of hippocampus brain slices ex vivo were used to detect the situation of hippocampus neuron damage and the protective effect of serum containing components of JWSNS.The opening probability and the average opening time of NMDA receptor channels were detected by attach on cell patch clamp,the Ca2+ concentrations in single cell of hippocampus neurons were detected by Tillvis ION software.Results CMUS could decrease the sucrose preference and the weights of rats(P
