Exploration on retention time of urokinase after performing lateral ventricle drainage in the ;treatment of severe ventricular hemorrhage / 中国医师进修杂志

ABSTRACT

Objective To evaluate the effect of retention time of urokinase on hematoma dissipation in the treatment of severe ventricular hemorrhage by lateral ventricle drainage. Methods The clinical data of 62 patients with severe ventricular hemorrhage and having received bilateral ventriculostomy were retrospectively analyzed. These patients was divided into 3 groups according to the retention time of urokinase A group (20 patients, retention time 1 h), B group (22 patients, retention time 2 h) , and C group (20 patients , retention time 3 h).The number of patients with complete hematoma dissipation at different time in each group were compared. Results At 5-6 d, 7-9 d and 10-12 d after operation, the number of hematoma dissipation in A group was 2, 5, 13 cases, in B group was 5, 13, 4 cases, and in C g group was 3, 13, 4 cases. The number of hematoma dissipation patients in three groups had significant difference (P=0.008), the number of hematoma dissipation patients between A group and B group, and between A group and C group had significant differences (P=0.005, 0.012), but there was no significant difference between B group and C group (P=0.621). The complication rate in three groups had no significant difference (χ2=2.540, P=0.281). Conclusions The 2 h retention time of urokinase is more suitable for the patients with severe ventricular hemorrhage who underwent external drainage.
