OBJECTIVE

To compare the hemostatic effect between absorbable hemostatic fluid gelatin (HFG) and absorbable gelatin sponge(GS) during operation of unilateral open-door cervical expansive laminoplasty.

METHODS

The clinical data of 83 patients underwent unilateral open-door cervical expansive laminoplasty from February 2014 to May 2016 were retrospectively analyzed. According to the used hemostatic materials, patients were divided into two groups. In HFG group, there were 30 males and 11 females, ranging in age from 29 to 81 years, with an average of(55.6±11.6)years; 14 cases were simple cervical spinal stenosis, 9 were cervical spinal stenosis and ossification of posterior longitudinal ligament, and 18 were cervical spinal stenosis complicated with multiple cervical disc herniation. And in GS group, there were 32 males and 10 females, ranging in age from 36 to 78 years, with an average of (55.4±11.1) years; 12 cases were simple cervical spinal stenosis, 10 were cervical spinal stenosis complicated with ossification of posterior longitudinal ligament, and 20 were cervical spinal stenosis complicated with multiple cervical disc herniation. There was no significant difference in the age, gender, and disease categories of patients between two groups (>0.05). The operative time, intraoperative bleeding, postoperative drainage, and postoperative complications were compared between two groups.

RESULTS

The average operative time, intraoperative bleeding, and postoperative drainage in HFG group were(137.2±30.0) min, (156.1±74.6) ml, and (212.1±67.6) ml, respectively; and in GS group were (154.8±33.5) min, (242.9±120.7) ml, and(303.3±115.5) ml, respectively. There were significantly differences in above items between two groups(<0.05). No acute heamatoma or related complications was found postoperatively.

CONCLUSIONS

Compared with GS, HFG can obviously decrease operative time, intraoperative bleeding, and postoperative drainage. It is a safe and effective hemostatic material for the operation of unilateral open-door cervical expansive laminoplasty.
