重庆市主城区120院前创伤急救情况调查

目的调查重庆市主城区120院前创伤急救情况。方法从重庆市急救医疗中心120指挥系统数据库提取2004年1月～2011年12月(8年)重庆市主城区院前创伤急救数据进行统计分析。结果 (1)8年间总共101 496次院前创伤急救,其中交通伤占68.23%,坠落伤占2.52%,刀砍伤占2.21%,其它创伤占26.2%;2007年1月～2011年12月院前创伤急救次数较2004年1月～2006年12月明显增加;(2)创伤发生频率最高依次为9月、5月、7月,最低依次为2月、1月、12月,夏季发生频率高于冬季;(3)不同致伤原因创伤发生高峰/低谷时段分别为:交通伤08～22时/00～06时;坠落伤08～12时与14～16时/00～06时,刀砍伤20～02时/04～08时,自杀10～16时/02～08时,烧烫伤8～10时与16～18时/02～06时;以上各类伤P<0.05。结论创伤发生与当地地理环境、道路与城乡建设、工农业生产、交通运输、社会治安、气候和人文等有关,且呈逐年明显增加的趋势,不同致伤原因创伤发生频率、高峰和低谷各有特殊规律,院前急救应根据这些规律制定相应的应对策略,对提高院前创伤急救反应能力和救治水平将具有重要意义。

An investigative study on prehospital trauma care in the downtown area of Chongqing

Objective To investigate prehospital trauma care in the downtown area of Chongqing municipality.Methods The data of prehospital trauma care of Chongqing municipality from Jan.2004 to Dec.2011 were collected from the computer database of Chongqing Emergency Medical Center.Results The total number of prehospital trauma care from Jan.2004 to Dec.2011 was 101496 times,road traffic trauma accounted for 68.23%,falling injuries 2.52%,and knife cut injuries 2.21%.The total number of prehospital trauma care from 2007 to 2011 had a significant increase in comparison to the period from 2004 to 2006.The highest trauma incidences by months were ranked in Sep.,May and Jul..The lowest incidences by months were ranked in Feb.,Jan.and Dec..More injuries occurred in summer than in winter（P〈0.05）.Traffic injuries of the highest incidence occurred in the period of 8-22 o’clock,the lowest incidence in the period of 0-6 o’clock（P〈0.05）;falling injuries of the highest incidence occurred in the period of 8-12 o’clock,14-16 o’clock,the lowest incidence in the period of 0-6 o’clock（P〈0.05）;knife cut injuries of the highest incidence occurred in the period of 20-2 o’clock,the lowest incidence in the period of 4-8 o’clock（P〈0.05）;suicide of the highest incidence occurred in the period of 10-16 o’clock,the lowest incidence in the period of 2-8 o’clock（P〈0.05）;burn and scald injury of the highest incidence occurred in the period of 8-10 o’clock,6-18 o’clock,the lowest incidence in the period of 2-6 o’clock（P〈0.05）.Conclusion Trauma occurrence is related to factors involving the geographical conditions,road traffic,construction and development in urban and rural areas,industrial and agricultural production,transportation,local public security,weather,and culture.The incidence of trauma also has significantly increased year by year.Different mechanisms of injury have different characteristics in the occurrence frequency and time interval.It is very important to make the strategies based on this study findings for improvement of trauma emergency response capability and treatment level.
