Research on the application of "H shaped" single-tube double-lumen drainage tube in the treatment of chronic subdural hematoma

Abstract

To explore the effect of chronic subdural hematoma external drainage surgery using self-made "H shaped" flush type single-tube double-lumen drainage tube. There were 56 cases chosen from the First Affiliated Hospital of Bengbu Medical College between Jan 2013 and Aug 2015. These patients with unilateral chronic subdural hematoma requiring surgery to place drilling external drainage catheter were randomly divided into group A (21 cases, using self-made single-tube double lumen "H shaped" drainage tube) and group B (35 cases, traditional silicone drainage tube), then the residual liquid volume after drainage on the first day, the days that the tube stay in body and the residual fluid volume after removing the tube were compared between the two groups. The residual liquid volume after drainage on the first day in group A was (23±15)ml, in group B was (31±15)ml. The days that the tube stay in body in group A was (2.7±1.0)d, in group B was (3.3±1.1)d, the two groups had statistical differences (P<0.05). The residual fluid volume after removing the tube in group A was (13±7) ml, in group B was (16±8)ml, but the data in these two groups had no significantly statistical differences (P>0.05). The effect of self-made "H shaped" flush type single-tube double-lumen drainage tube in the drainage of chronic subdural hematoma drainage is good, with short tube stay in the body; therefore, it is a safe and effective way to treat chronic subdural hematoma, and is worthy of clinical application.
