Objective To discuss the effect of restrictive fluid resuscitation on trauma patients with uncontrolled hemorrhagic shock and first aid.Methods Totals of 100 patients with trauma patients with uncontrolled hemorrhagic shock randomly divided into control group and observation group with each group of fifty cases,and control group adopt conventional liquid recovery method,observation group was given restrictive fluid resuscitation.Observed and compared two groups of patients cure rate,mortality,and ARDS incidence,MODS incidence,recovery liquid quantity,recovery time,satisfaction of patients and families on first aid job.Results The incidence of patients' cure rate,mortality,ARDS,and MODS in observation group respectively were 80％,20％,4％,8％ and that in control group were 60％,40％,28％,38％,and the difference was statistically significant (x2 =7.24,6.95,8.63,7.84,respectively; P ＜ 0.01).Recovery time in observation group were significantly shorter than that in control group [(95.67 ± 25.03) vs (200.18 ± 35.12) mins; t =5.23,P ＜ 0.01],and the satisfaction of patients and families to first aid job in observation group was higher than that in control group [(98.45 ± 0.91) vs (91.12 ± 4.07) ; t =4.59,P ＜ 0.01)].Conclusions Trauma patients with uncontrolled hemorrhagic shock application restrictive fluid resuscitation,and at the same time,according to the first aid program first aid care,can reduce the occurrence of MODS and ARDS patients,reduce the mortality and improve the cure rate and satisfaction of patients and families on first aid.
