Objective To explore the effect of trauma control concept on severe multiple injuries.Methods From March 2016 to March 2018,74 emergency patients with severe multiple injuries were selected in Yiwu Central Hospital.The patients were divided into the observation group and the control group according to the digital table method,with 37 cases in each group.The control group was treated with one-time surgical treatment,and the observation group was given treatment measures for severe multiple trauma in emergency department under the concept of trauma control.The recovery time of body temperature,the recovery time of prothrombin (PT),the time of shock correction,the occurrence of complications,and the therapeutic effect were compared between the two groups.Results The body temperature recovery time,PT recovery time and shock correction time in the observation group were (6.73 ± 3.29) h,(5.18 ± 1.89) h and (5.84 ± 3.14) h,respectively,which were shorter than those in the control group [(9.85 ± 1.62) h,(9.86 ± 2.41) h,(8.45 ± 0.87) h],and the differences were statistically significant (t =5.175,9.295,4.873,all P ＜0.05).The incidence rate of complications in the observation group was 8.11％ (3/37),which was lower than that in the control group [32.43％ (12/37)],the difference was statistically significant(x2 =6.773,P ＜ 0.05).The cure rate of the observation group was 97.30％ (36/37),which was higher than that of the control group [91.89％ (34/37)],but there was no statistically significant difference (P ＞ 0.05).Conclusion The treatment effect of severe multiple injuries under the concept of trauma control is obvious.It is an effective and feasible method,which can effectively reduce the complications and fatality rate.
