Effect of preoperative single target administrating of fibrinogen on intraoperative bleeding and coagulation function in PLIF / 重庆医学

ABSTRACT

Objective To investigate the effect of preoperative single target administrating of fibrinogen(FIB)on the intraop-erative bleeding and coagulation function in posterior lumbar interbody fusion (PLIF)operation.Methods 60 cases of lumbar inter-vertebral disc herniation(LDH)undergoing elective PLIF operation were divided into two groups according to the preoperative FIB levelsnormal control group(NC,FIB≥3.0 g/L,n=20)and low FIB group(FIB<3.0 g/L,n=40).The low FIB group was ran-domly re-divided into 2 groupsthe low HIB control group(LC,n=20)and the preoperative single FIB administrating group(PF, n=20).After anesthesia induction,the PF group was given FIB;the LC and NC groups were given the same volume of saline solu-tion as solvent volume required by administrating FIB dose.The change of blood coagulation 4 indexes were detected and the activa-ted clotting time(ACT),coagulation time(CR)and platelet function(PF)were detected by the sonoclot analyzer before and after drug administrating.The bleeding amount was weighed after ending operation.Results The FIB concentration after administrating in the PF group was (3.75±0.23)g/L,which was significantly higher than (2.62±0.33)g/L in the NC group and (2.23±0.22) g/L in the LC group,the differences among 3 groups were statistically significant(P <0.05);the CR value after administrating in the PF group was (21.42±7.15)U/min,which was higher than (18.21±5.62)U/min in the NC group and (15.21±5.63)U/min in the LC group.The bleeding amount in the PF group was (516.74±135.53)g,which was lower than (660.71±119.34)g in the NC group and (726.72±160.47)g in the LC group,the difference among 3 groups had statistical significance(P <0.05).Conclusion Preoperative single target administrating of fibrinogen can effectively increase the FIB level,improve the blood coagulation func-tion and reduce the periaoperative bleeding amount.
