Abstract:
OBJECTIVETo determine the effect of albumin administration on lung injury in traumatic/hemorrhagic shock (T/HS) rats.
METHODSForty-eight adult Sprague-Dawley rats were divided into three groups randomly (n=16 in each group): Group A, Group B, Group C. In Group A, rats underwent laparotomy without shock. In Group B, rats undergoing T/HS were resuscitated with their blood plus lactated Ringer's (twice the volume of shed blood). In Group C, rats undergoing T/HS were resuscitated with their shed blood plus additional 3 ml of 5% human albumin. The expression of polymorphonuclear neutrophils CD18/CD11b in jugular vein blood was evaluated. The main lung injury indexes (the activity of myeloperoxidase and lung injury score) were measured.
RESULTSSignificant differences of the expression of CD18/11b and the severity degree of lung injury were founded between the three groups. (P<0.05). The expression of CD18/CD11b and the main lung injury indexes in Group B and Group C increased significantly compared with those in Group A (P<0.05). At the same time, the expression of CD18/CD11b and the main lung injury indexes in Group C decreased dramatically, compared those in Group B (P<0.05).
CONCLUSIONSThe infusion of albumin during resuscitation period can protect lungs from injury and decrease the expression of CD18/CD11b in T/HS rats.
