ABSTRACT
Objective To compare the effects of different resuscitation pressure on lung function of rats with uncontrolled hemorrhagic shock.Methods Uncontrolled hemorrhagic shock model of rats was built.Sixty Sprague-Dawley rats were randomly sent into six groups NC group (the control group),NF group (shock but non-resuscitation),NS40,NS60 group (limited fluid resuscitation),NS80,NS100 group (large-volume fluid resuscitation).When the mean arterial pressure (MAP) reached between 35 mm Hg to 40 mm Hg (1 mm Hg=0.133kPa) resuscitation was begun,normal saline infusion was used to maintain the following desired endpoints.After the fluid resuscitation for one hour,rats of each fluid resuscitation group were given haemostasis and all-out fluid resuscitation,including blood infusion,to maintain the rats' MAP at 90 mm Hg.Results Findings showed that the blood loss in limited fluid resuscitation groups was significantly lower than that in large-volume fluid resuscitation groups at the situation of uncontrolled hemorrhagic shock,damage to lung tissue pathology and acidosis were significantly lower than those in large-volume fluid resuscitation groups.Nine rats in NS60 group survived 72 hours.Three rats in NS40 group survived 72 hours.No rat in NF group as well as in both NS80 and NS100 groups survived 72 hours.Conclusions Uncontrolled hem-orrhagic shock in trauma and different pressure of fluid resuscitation can cause lung injury to varying de-grees.Limited fluid resuscitation provide significant protective effects against such injuries.
