Objective To investigate the difference in the incidence of postextubation throat complications between severe patients treated with methylprednisolone intravenously with and without budesonide suspension inhalation immediately after postextubation.Methods 75 patients with tracheal intubation were divided into group A (n=36,patients received methylprednisolone 40 mg intravenously before extubation) and group B (n=39,patients received methylprednisolone 40 mg intravenously before extubation and budesonide suspension inhalation 1 mg immediately after extubation).Postextubation thoat complications including sore throat,hoarseness and laryngeal edema were observed in the two groups.Clinical efficacies in the two groups were analyzed.Results The incidences of sore throat,hoarseness and laryngeal edema after extubation were 50.0％ (18/ 36),55.6％ (20/36) and 5.6％ (2/36) respectively in group A and 30.8％ (12/39),35.7％ (14/ 39) and 2.6％ (1/39) respectively in group B.There were no significant differences in the incidences of sore throat,hoarseness and laryngeal edema after extubation between the two groups,but the tendencies of complication incidences were decreased in group B as compared with group A.Conclusions The application of intravenous methylprednisolone before extubation and budesonide suspension inhalation after extubation can reduce the incidences of sore throat,hoarseness and laryngeal edema after extubation.

Objective To estimate the success rate of emergency endoscopic treatment in patients with esophagogastric variceal bleeding using self-made gastroscope outer casing and to investigate bow to prevent complications. Methods A total of 11 patients with esophagogastric variceal bleeding underwent endoscopic treatment with self-made gastroscope outer casing, which consisted of a wire reinforced plastic casing (1.05 cm in inner diameter, 1.35 cm in outer diameter and 50 cm in length), a 3.8 cm×3.8 cm balloon fixed on the casing head and its cavity connected to the gas pipeline placed in casing tail, an anti-reflux pad in the insert entrance of the endoscope tail as well.as a flushing hole. The endoscopy was introduced to the esophagus or stomch together with outer casing to wash and pump the hematocele out from the side of flushing hole. In patients with hemorrhagic lesion in esophageal vein, the balloon was used to press bleeding vein and intravascular sclerotherapy was performed simutanously. In those with hemorrhagic lesion in gastric vein, the balloon was pressed on esophageal vein near to the cardia and intravascular sclerotherapy was performed. Results During the process of examination, the hemorrhagic lesion was fully exposed because of flushing, and bleeding was controlted in all patients after sclerotherapy. No complication such as aspiration or perforation was seen. Conclusions For emergency endoscopic treatment of esophagogastric variceal bleeding, gastroscope outer casing is helpful in removing intragastric hematocele and maintaining a clear field of vision. It can be effectively improving the efficacy of sclerot herapy.

Objective To develop a simple and effective method for monitoring cortical ischemia after temporary occlusion of the parent arteries during anterior circulation intracranial aneurysm surgery. Methods Fifty-two patients with anterior circulation aneurysm (58 aneurysms) received craniotomy from April to November 2008, and at the same time,cortical electroencephalograpby (EEG) and scalp EEG were monitored during the surgery.According to the international 10/20 electrode placement system, scalp electrodes were placed on O1, O2, P3, P4, T5, and T6 for monitoring the changes in the depth of anesthesia. A cortical strip electrode was placed on the cortical surface supplied by the artery that was possibly blocked during the operation, which was used to monitor the possible cortical ischemia. For patients who had cortical EEG suppression after the temporary occlusion of the parent arteries Were compared with the changes of scalp EEG. Whether there were ischemic events in the corresponding supply territory after vascular occlusion were observed after surgery. Results Of the 58 aneurysms, 40 aneurysms and 41 major arteries were occluded temporarily. After being occluded temporarily in 19 arteries of 18 patients, cortical EEG changed significantly,while scalp EEG did not change significantly. Only 9 patients had ischemic events in the corresponding supply territories after the occlusion in the cortical EEG significant change group. The changes in the depth of anesthesia had the consistent impact on cortical and scalp EEG. Conelusions Simultaneous monitoring of cortical and scalp EEG is a simple and effective method for monitoring cortical ischemia during anterior circulation intracranial aneurysm surgery, and may effectively identify the effect of anesthesia on EEG.
