Comparison the efficacy of hemorrhage control of Surgiflo Haemostatic Matrix and absorbable gelatin sponge in posterior lumbar surgery: A randomized controlled study

To compare the hemostatic effect of hematostatic agent Surgiflo and absorbable gelatin sponge (AGS) in posterior lumbar surgery. A total of 60 cases were recruited during August 2016 and June 2017 according to the inclusion and exclusion criteria. Patients were randomly allocated to the Surgiflo Haemostatic Matrix (SHM) group or the AGS group (AGS) by computer-generated randomization codes. The success rates of hemostasis for 3 minutes and 5 minutes, the time of operation, the amount of intraoperative bleeding, the volume of autogenously blood transfusion, the amount of blood during hemostasis, the amount of blood transfusion, and BP, RBC, HCT, HB of preoperative, 2 to 3 days, and 5 to 7 days following operation were recorded to compare. Daily drainage and all adverse events after operation were also compared. All the patients were followed up for at least 1 month. The RBC and HCT of the AGS group before operation were lower than those in the control group (P = .039, P = .029), but there was no difference after operation (P >.05). In the control group, 19 cases were successfully hemostatic in 3 minutes, 4 cases were successful in 5 minutes, and 7 cases were combined with hemostasis. In the SHM group, it was 22, 3, and 5 cases respectively. There was significant difference in blood loss during hemostatic process between the 2 groups (P
