Objective To investigate the usefulness of HC visual laryngoscope designed for unskilled junior emergency resident doctors in respect of increasing the efficiency and success rate of emergency tracheal intubation.Methods A total of 80 patients needed the emergency tracheal intubation were at first divided into two groups randomly (random number).Patients in group A were operated by junior emergency resident doctors and patients in group B were operated by well experienced attending doctors.Then,the two groups of patients above were divided into two groups randomly (random number).Patients in group N were operated with conventional laryngoscope and patients in group HC were managed with HC visual laryngoscope.Then comparisons of the success rate of glottis exposure,the one-time success rate of tracheal intubation,the success rate of tracheal intubation,the complications,the number of attempt in successful intubation cases and the operative time consumed for successful intubation cases among the groups were done.Results (1)The success rate of glottis exposure,the one-time success rate and the success rate of tracheal intubation in group A-HC were 90%,70% and 90%,respectively which were significantly higher than those (50%,20% and 45%)in group A-N (P <0.05).The rate of complication,the number of attempt and operative time consumed for intubation cases in group A-HC were respectively 15%,(1.28 ± 0.43)and (31.44 ±5.06 ) s,which were significantly less than those [45%,(1.89 ±0.79 )and (45.89 ±4.99) s in group A-N (P <0.05 ).(2)The success rate of glottis exposure,the one-time success rate and the success rate of tracheal intubation in group B-N were 80%,65% and 80%, respectively which were significantly higher than those (50%,20% and 45%)in group A-N (P <0.05). The rate of complication,the number of attempt and operative time consumed for successful intubation cases in group B-N were 15%,(1.25 ±0.41)and (39.31 ±4.23)s,respectively which were significantly less than those [45%,(1.89 ±0.79)and (45.89 ±4.99)s]in group A-N (P <0.05).(3)There were no significant statistical differences in above results between group A-HC and group B-HC (P >0.05 ). Conclusions HC visual laryngoscope used by unskilled junior emergency resident doctors for emergency tracheal intubation,could increase success rate of glottis exposure,decrease the number of attempt of intubation,decrease rate of complication,shorten operative time required for intubation thus improving efficiency and success rate of emergency tracheal intubation,and maybe narrow the skill gap between unskilled junior resident doctors and well experienced attending doctors in respect of emergency tracheal intubation.

Objective The aims of this study were to analyze the clinical characteristics and laboratory test results of stageⅣ lung cancer patients with Pulmonary thromboembolism(PTE),and to find out the risk factors for pulmonary thromboembolism. Methods A total of 70 patients with stage IV lung cancer were selected from the First Affiliated Hospital of Nan Chang University from January 2011 to October 2017. Blood routine,blood biochemistry,coagulation function,tumor markers(CEA,CA199,CA125, NSE,Cyfra211)and multi-slice spiral CT pulmonary angiography(CTPA)were collected in these patients. Univariate analysis was applied to compare the clinical features and laboratory tests between PTE and non-PTE groups. Multivariate logistic regression analy-sis was applied to explore significant risk factors of PTE. Results Univariate analysis showed that serum albumin,blood leukocyte, neutrophil percentage,increased Cyfra211 and abnormal tumor markers were risk factors for PTE in patients with stage IV lung canc-er. Multivariate logistic regression analysis showed that the number of abnormal tumor markers ≥4(OR=7. 016,95% CI:1. 916 ~25. 686)was an independent risk factor for PTE in stage IV lung cancer. Conclusion The number of abnormal tumor markers is an independent risk factor for pulmonary thromboembolism in stageⅣlung cancer. When the number of abnormal tumor markers is≥4, it is necessary to highly alert the possibility of stage IV lung cancer with pulmonary thromboembolism.

Objective To explore the role of clinical pharmacists in the treatment of drug poisoning by analyzing the clinical pharmacist's participation in the treatment of a patient with sodium valproate poisoning. Methods Clinical pharmacists measured the plasma concentration of sodium valproate to inform the doctor to diagnose illnesses. At the initial stage when the concentration is high, to eliminate the free drug by continuous venous-venous hemodialysis-filtration (CVVHDF). Then, the combined drug was cleared by hemoperfusion (HP). Results The blood concentration dropped by half at the first CVVHDF and decreased obviously after two HPs. After stable observation in five days’ course of disease, the blood concentration was maintained at a low level and the patient was cured and discharged. Conclusion The implementation of the blood purification program under the monitoring of the blood drug concentration with the participation of pharmacists is helpful for the rescue of drug overdose and is worthy of promotion.
