ABSTRACT

Objective:

After using proximal femoral nail antirotation (PFNA) fixation to treat femoral intertro-chanteric fractures (ITFs), closed negative pressure drainage systems are often used for drainage, but the clinical effect of this method is uncertain. A prospective randomized controlled trial study was conducted to analyze the negative effects of negative pressure drainage systems after PFNA fixation.

Methods:

Sixty patients with ITFs and underwent PFNA fixation were randomly divided into two groups. Patients in the drainage group were equipped with negative pressure drainage systems after PFNA fixation. At 4, 10, and 90 days after the surgery, the visual analog scale (VAS) score, analgesic dosage, thigh swelling width, wound and infection status, hemoglobin, hematocrit level, total blood loss and transfusion blood volume of the patients were recorded to evaluate the prognosis.

Results:

The total blood loss of the drainage group [(579.1±236.7) ml] was greater than that of the non-drainage group [(427.8±239.8) ml; P=0.01]. The transfusion blood volume of the drainage group [(443.3±176.3) ml] was greater than that of the non-drainage group [(307.8±155.4) ml; P=0.01]. Compared with the non-drainage group, the drainage group had a higher VAS score at 4 days after the surgery (2.3±0.6, P=0.02). There was no difference between the two groups in analgesic dosage, thigh swelling width, wound infection and hematoma, hospital stay and the total number of complications (all P>0.05).

Conclusions:

In the patients with ITFs treated with PFNA fixation, the transfusion blood volume and total blood loss of the patients in the drainage group are higher than those in the non-drainage group. In addition, drainage systems may not have short-term benefits for postoperative wound conditions.
