Objective: The objective of the present study was to explore the resuscitative effect of small-volume resuscitation on uncontrolled hemorrhagic shock in emergency. 
Methods: In this study, the resuscitative effects in 200 trauma patients with uncontrolled hemorrhagic shock in emergency were studied. Half of these patients were infused with hypertonic/hyperoncotic fluid (small-volume resuscitation group, n=100), whereas the rest were infused with Hespan and lactated Ringer’s solution (conventional fluid resuscitation group, n=100). The changes in hemodynamics, coagulation function, blood biochemistry, blood hematology, and the average infusion volume in both the groups were comparatively studied. 
Results: It was found that the hemodynamics were improved in both the groups after resuscitation. Interestingly, compared with trauma patients infused with Hespan and lactated Ringer’s solution, the growth rate, range, and time duration of the mean arterial pressure of the patients in small-volume resuscitation group increased significantly, and the shock index decreased progressively; in the 60th min after the resuscitation, blood index including hemoglobin, hematocrit, red blood cells, white blood cells, and platelet declined, whereas prothrombin time and activated partial thromboplastin time were prolonged in both the groups, but these changes were less obvious in the small-volume group. In addition, the average infusion volume of patients in the small-volume group was less than that of patients in conventional fluid resuscitation group.
Conclusion: Featured with small infusion volume and less influence to coagulation function and homeostasis of human body, small-volume resuscitation possesses a significantly higher resuscitative effect. Therefore, trauma patients may have a better chance to maintain the hemodynamic stability and the survival rate, or recovery speed will be increased when traditional aggressive fluid resuscitation is replaced by small-volume resuscitation.
