Objective To compare the effect between i-gel mask and SHPA mask in the airway management of general anesthesia.Methods Sixty patients of general anesthesia with ASA I or Ⅱ were randomly divided into two groups:i-gel mask group (30 cases) and SLIPA group(30 cases).After intubation and general anesthesia,fiberoptic bronchoscopy was used to detect and evaluate.The peak airway pressure,mean airway pressure,condition of the laryngeal mask intubation,time of intubation,time of extubation,time of recovery and the side effect occurrence of extubation were recorded.Results The time of anesthesia,time of operation,time of extubation,time of recovery,achievement ratio of first time,achievement ratio of second time,time of intubation,peak airway pressure and mean airway pressure had no significant difference between two groups (P ＞ 0.05).The airway seal pressure in i-gel mask group was significantly higher than that in SL1PA group [(29 + 6) cm H2O (1 c m H2O =0.098 kPa) vs.(23 ± 4) cm H2O] (P ＜ 0.05).For the grade of fiberoptic bronchoscopy in i-gel mask group,there was 27 patients in I grade,3 patients in Ⅱ grade.But in SL1PA group,there was 3 patients in I grade,4 patients in Ⅱ grade,13 patients in Ⅲ grade,10 patients in ⅣVgrade.There was significant difference between two groups (P ＜ 0.05).There were none of regurgitation in two groups.Conclusions The i-gel mask and SLIPA mask can provide the same effective ventilation.The i-gel mask has higher airway seal pressure,less side effect during the intubation and extubation,and have better airway management of general anesthesia.

Objective To explore the factors affecting implementation of basic nursing by practice nursing students and countermeasures.Methods By cluster sampling, from November to December 2015, 119 nursing students from Xiangtan Medicine & Health Vocational College who had completed their 10-month practice in Hunan Provincial People's Hospital, were selected as objects and were surveyed by a self-designed questionnaire about causes and countermeasures of implementation of basic nursing among practice nursing students.Results The nursing students' negative attitude was the most important cause affecting implementation of basic nursing, which accounted for 0.861 of the original variable; allocating nursing staff more reasonably, establishing an incentive mechanism to overcome occupation burnout, and promoting humanistic care by concerning psychological needs were significant in promoting implementation of basic nursing, each accounting for 0.719, 0.660 and 0.613 of the original variables.Conclusions Nursing educators should strengthen guidance to the nursing students, help them to be more aware of basic nursing, change their negative attitude, allocate nursing staff more reasonably, establish incentive mechanism and pay more attention to their psychological needs.

Objective:To explore the enhancement effect of different concentrations of contrast media on blood vessels and hollow organs in CT enterography.Methods:Sixty patients with CT enterography were enrolled from January to August 2019 at Shanghai Ninth People's Hospital, and were prospectively randomly divided into three groups (group A: 90 ml 400 mg/ml contrast media, group B: 90 ml 350 mg/ml contrast media, and group C: 79 ml 400 mg/ml contrast media). Evaluation parameters included CT value, signal noise ratio (SNR) and contrast noise ratio (CNR) of main abdominal vessels (abdominal aorta, superior and inferior mesenteric atery, jejunal artery, ileum artery, superior and inferior mesenteric vein), jejunum, ileum and inflammatory bowel disease. The overall image quality and direct jejunum ileum artery quality scores were evaluated. One-way ANOVA was used to compare the parameters among the three groups.Results:There was no statistical difference in CT value, SNR and CNR of each measurement index among the three groups in plain scan ( P>0.05). The CT value, SNR and CNR of abdominal aorta, superior mesenteric artery, inferior mesenteric artery, jejunal artery and ileal artery in group A and C were higher than those in group B in arterial phase ( P<0.05), but there was no significant difference between group A and group C ( P>0.05). The CT value, SNR and CNR of superior mesenteric vein, inferior mesenteric vein, normal jejunum, ileum and inflammatory lesions in group A were higher than those in group B and C in venous phase ( P<0.05), but there was no significant difference between group B and group C ( P>0.05). The overall image quality scores of group A, B and C were (3.8±0.7), (3.4±0.6), (3.4±0.6), respectively, with no significant difference ( F=3.075, P=0.054). The direct jejunum ileum artery scores of the three groups were (3.5±0.5), (3.1±0.5), (3.4±0.5), respectively, the difference was statistically significant ( F=3.684, P=0.031). Conclusion:At the same injection rate and scanning parameters, contrast media at 400 mg/ml can provide better vessel and hollow organ enhancement.

Objective To explore the effects of different sleep positions on the apnea hypopnea index (AHI) of obstructive sleep apnea hypopnea syndrome (OSAHS) patients under the state of sleep. Methods Totally 98 OSAHS patients from the ENT clinic and the inpatient department of a tertiary hospital of Changsha from May to July 2015 were selected as the research objects. By using polysomnography detection instrument, the AHI index of patients under different sleeping postures were observed and compared between two groups. Results For 98 patients, the AHI index was (16.51±42.08) in their right lateral position, the AHI index was (20.05±66.11) in left lateral position, AHI index was (22.04±86.39) in supine position, and the AHI index was (53.31±122.88) in prone position. The differences of AHI index in prone position were statistically significant compared with the right lateral position, the left lateral position and supine position (P < 0.05). Conclusions The right lateral position is the best position for OSAHS patients under the state of sleep, and it can decrease upper airway pressure and reduce the sleep apnea and hypopnea during sleep.
