<正>Objective:To investigate the effect of preoperative limited fluid resuscitation on the patients with traumatic shock.Methods:Eighty-nine patients with multiple injuries complicating with shock were treated in Changhai Hospital between January 2002 to October 2005 and were divided into 3 groups accord ing to the preoperative levels of systolic blood pressure（SBP）.SBP of group A and group B were about 70 and 80 mmHg

respectively;and the SBP of group C was over 90 mmHg.Results:（1）There was no sig- nificant difference in age

gender

and injury severity score（ISS）

initiated resuscitation time and initiated operation time among the 3 groups.Preoperatively

there was significant difference in the amount of fluid resuscitation and infused erythrocyte suspension among group A

B and C（1687±96 ml

2096±87 ml. 2976±93 ml

P<0.05;and 294±110ml

404±113 ml

7984±230ml

P<0.05）.（2）The hemoglobin level in group C（94±45 g/L）was lower than that in group A（110±22 g/L）and group B（103±24 g/L）（P<0.05）.However

there was no significant difference in the level of hemoglobin between group A and B.（3）There was no significant difference in the incidence of acute renal failure（ARF）among the 3 groups.The incidence of acute respiratory distress syndrome（ARDS）of group C（31.2%）was higher than that of group A（16.7%）and group B（18.2%）（P<0.05）.The mortality of group C（34.4%）was higher than that of group A（12.5%）and group B（12.1%）（P<0.05）.Conclusion:Preoperative limited resuscitation applied on patients with traumatic shock can reduce blood loss

incidence of ARDS and mor tality.
