ABSTRACT
Objective To screen a set of key techniques for new medical rescue aircraft ICU care for peacetime and wartime.Methods The study used the literature review and field research method to propose the initial technical indicators.The consultation questionnaire was developed by expert panel method.Delphi method was applied to conduct two rounds of consultation among 16 experts from different fields.Analytic hierarchy process and TOPSIS comprehensive evaluation method were used to analyze and summarize data.Results In two rounds of consultation,the positive coefficients of experts were 100％,the authority coefficient of experts was 0.958,and Kendall co ordination coefficients were 0.568,0.525,0.474,and the differences were statistically significant (P＜0.05).The new medical rescue aircraft ICU care key techniques for peacetime and wartime was established finally,including 4 firstlevel indicators,37 second-level indicators,and there were 12 basic care techniques,8 specialty care techniques,10 emergency care techniques,and 7 war wound care techniques.Conclusion Key techniques for new medical rescue aircraft ICU care has high scientificity and feasibility,and experts' opinions are concentrated,which can provide additional safeguard for the transit of critically ill patients in the air.
ABSTRACT
Objective To evaluate the effect of single hand pipe method on venous indwelling needle puncture. Methods Literature about the impact of single hand pipe method on venous indwelling needle puncture was retrieved from digital databases of PubMed, Medline, EMbase, The Cochrane Library, SinoMed, VIP database, China National Knowledge Infrastructure(CNKI), and WanFang Data. The quality of literature was evaluated by the Cochrane Handbook (5.1.0). The Meta data was analyzed by RevMan 5.3. Results Ten random control trials were included . Ten studies indicated that single hand pipe method increased success rate of puncture[related to the risk(RR)=1.16, 95%confidence interval(CI) 1.11-1.22]. And, it decreased the complication rate (3 studies) (RR=0.32, 95%CI 0.13-0.79) and pain rate(2 studies) (RR=0.25, 95%CI 0.13-0.47) as well as shorten the time of tube(2 studies) (WMD:-1.68, 95%CI-2.44--0.93). Conclusions Single hand pipe method can improve a puncture success rate and reduce complications and pain rate and shorten the time of tube, so that get more time to rescue the patient, and improve the level of the working efficiency and nursing for the nursing staff. In addition, to some extent, save manpower. It is worth being popularized.
ABSTRACT
Objective To investigate the effect of high altitude aviation on the pressure and diameter of the trachea cannula cuff after injecting air or water. Methods In the circumstance 5 km height and 795 hPa cabin pressure, the air injected cuffs were divided into two groups, one was under the ground circumstance, the other was in the high altitude aviation environment. The volumes of injected air were 5 ml, 7 ml, 9 ml, 11 ml, 13 ml, 15 ml, 17 ml, and the cuff pressure and its diameter were measured. The water injected cuffs were also divided into two groups of ground and high altitude aviation environment. The volumes of injected water were 10 ml, 12 ml, 14 ml, 15 ml, 16 ml, and the cuff pressure and its diameter were measured. The results were compared between the ground circumstance and high altitude aviation environment. Results The diameter of injection air group versus under the ground circumstance group had the statistical significance (t=5.000-9.449, P0.05), while different air volume injection had significant effect on pressure and diameter (F=5.132, 5.980, P<0.01). When the water volume was 10 ml, the cuff pressure was (24.00±4.62) cmH2O (1 cmH2O=0.098 kPa) , which was appropriate to the range of cuff pressure (20-30 cmH2O). Conclusions In high altitude aviation environment the trachea cannula cuff should adopt water injection, and the best water volume is about 10 ml.
ABSTRACT
OBJECTIVE To study the measures of strengthening the nursing management in the nursing department to prevent and control nosocomial infection.METHODS Establishing nosocomial infection management organization;staff training;modifying the related rules and regulations;setting up the supervision and inspection system;and academic research of nosocomial infection were taken.RESULTS All nurses consciously implemented the rules.The systems of nosocomial infection control had developed and standardized and the rate of nosocomial infection have decreased.CONCLUSIONS Strengthening the nursing management in the nursing department could effectively prevent and control nosocomial infection.
ABSTRACT
Objective To study changes in ACE, LDH and AKP in BALF and blood after rapid decompression in rabbits. Methods Thirty healthy New-Zealand rabbits were randomly divided into low decompression group and rapid decompression group. The respective activity of ACE, LDH and AKP in BALF and blood of rabbits was measured. Results Various degrees of increase in activity of ACE, LDH and AKP in BALF were observed after rapid decompression. Conclusion The simultaneous enhancement of activity of these enzymes suggest that there was injury to the lung consistent with the degree of injury after rapid decompression.
