0bjective To compare the effect of closed airway management system and open suction system on distribution and drug susceptibility of pathogenic bacteria in lower respiratory tract of mechanical ventilated patients.Methods Fifty-nine cases in ICU who received mechanical ventilation for more than 48 h from May 2006 to Dec 2006 were randomly divided into two groups.Group A(29 patients)received closed—tracheal suction and Group B(30 patients)received open-tracheal suction.Quantitative bacteriological culture and sensitivity of antibacterial drugs were conducted on lower respiratory tract secretion samples.Results In group A，a total of 91 strains were isolated，in which a single pathogen infection(41.4％)was the most frequent，followed by mixed infection of two pathogens(34.5％)and three or more pathogens(24.1％).In group B，a total of 141 strains were isolated，in which three or more pathogen infection(53.33％)was the most frequent，followed by two pathogen infection(30％)and a single pathogen infection(16.7％ ).Pathogen distribution between the two groups was not significantly different(Pgt;0.05).Drug susceptibility test did not show significant difference in main pathogens between the two groups(Pgt;0.05).Conclusions Closed airway management system can reduce the infection or colonization of mixed pathogens，but can not change the distribution and drug susceptibility of pathogens.
Objective To analyze the injury characteristics and the rescue process and effects for the victims admitted in the People’s Hospital of Deyang City within 72 hours after 4.20 Lushan earthquake, so as to discuss how to adopt the emergency program to implement medical rescue in disaster relief. Methods The data of 25 earthquake victims admitted in the hospital from April 20th, 2013 to April 23rd, 2013 were collected to analyze age, gender, the location of injury, the injury state of different age groups, and the prognosis of victims. Results Of the 25 victims with injuries on 32 locations of the body, there were 20 cases with single injury (80.00%) and 5 cases with multiple injuries (20.00%). Most injuries were seen in four limbs, body surface, and soft tissues; and the incidence of single injury was higher than that of multiple injuries. The number of admitted victims was largest on the first day after earthquake, accounted for 92.00%, which was obviously higher than that on the second and the third day. Victims aged from 19 to 45 years old was more than those of other ages. Conclusion Scientific emergency command system and disaster emergency program play an high-efficient command role in disaster rescue, shorten the time of emergency response, and improve the ability of disaster rescue. The comprehensive capacity of self-rescue and well-organized rescue for disaster area can be improved as long as the general public is educated about the disaster emergency program and cooperative emergency drill. Meanwhile, smooth traffic and unobstructed communication are guaranteed in the disaster area, and the cooperative efforts are made by all walks of society.
Objective To discuss how to improve organization and management of first-aid nursing during the rescue work. Methods Data about the wounded patients in the Emergency Department of our hospital were collected from 12 to 21 May, 2008. The relevant information concerning the interventions and effects of the organization of first-aid nursing was analyzed. Results In the first ten days after the quake, 1 766 wounded patients were received and treated in the Emergency Department. The results of post-evaluation showed that the rescue work was successful including the first-aid path, rationality of the rescuer dispatch, management of the medical resources, collection of the patients information, and high-quality nursing. Conclusion Effective organization and management of first-aid nursing guarantee the rescue work.
