Application of choosing negative pressure by different sticky secretion different sticky secretion in continuous aspiration of subglottic secretion with mechanical ventilation / 现代临床护理

Objective To explore the effect of continuous aspiration of subglottic secretion at different negative pressure levels on mechanical ventilation. Methods Toally 142 patients were randomized by way of lottery into the control group (n=70) and the experiment group ( n = 72 ): the control group received continuous negative pressure aspiration of subglottic secretion at a negative pressure of 60 mmHg while the experiment group did 30~40 mmHg for grade I of the sticky secretion , 40~60 mmHg for gradeⅡ~Ⅲof the sticky secretion, respectively. The two groups were compared in terms of the rate of ventilator associated pneumonia (VAP), airway mucosal injury and cough. Result There was no significant difference in the rate of ventilator associated pneumonia (P>0.05), but the rates of airway mucosal injury and cough were lower in the experiment group than those of the control group (P < 0.05). Conclusion It is reasonable to choose different negative pressure levels based on stickiness of the secretions for mechanical ventilation, for it can prevent the ventilator associated pneumonia and airway mucosal injury.

A survey concerning the knowledge of the Chinese Guidelines of Diabetes Prevention and Treatment among medical staff from hospitals at different levels in Shanghai / 中华内分泌代谢杂志

To analyze and evaluate the knowledge of Chinese Guidelines of Diabetes Prevention and Treatment in Shanghai medical staff. 175 medical staff working in endocrinology or community health were enrolled and evaluated by a questionnaire of guidelines about the state of professional, training, and related knowledge. Only 16. 6% medical staffwere trained about the guidelines( 46. 67% from the general hospitals, 14. 75% from secod-level hospital and 7. 14% persons from the community hospitals, P＜0. 01 ). The total correct answer rate of the guidelines was 37. 36%. The correct rate of community hospitals was lower than others( P＜0. 05 ). The rate of doctors' was higher than nurses'( P＜0. 05 ). There were difference between doctors and nurses with the key point of diabetes care knowledge in different level hospitals. The effective method of clinical training in diabetes care should be explored. We still have to work hard to promote the effect of diabetes control and prevention. Effective training about the guidelines should be enhanced. The cooperation between general hospitals and community health institutions in diabetes prevention and treatment should be enhanced.
