Abstract
INTRODUCTION: The effect of using closed suction drainage system with the proximal femoral nail antirotation (PFNA) system fixation on outcomes in treating intertrochanteric fractures (ITFs) is still unknown. This prospective randomized controlled trial aimed to examine whether routine drainage is useful for PFNA fixation in ITFs. METHODS: A total of 80 patients with acute ITFs were treated with closed or mini-open reduction with PFNA fixationat the National Cheng Kung University Hospital and 60 eligible patients were randomized for whether to receive suction drainage. In clinical outcomes, the visual analog scale (VAS), morphine equivalent dosage, injured thigh width, body temperature, wound condition and wound infection were measured on postoperative day 1, 2, 4, 10, and 90. In laboratory outcomes, we evaluated hemoglobin and hematocrit levels postoperatively at different time points. Blood transfusion and total blood loss (TBL) were measured by Mercuriali's formula in millimeter. RESULTS: The results revealed that the amount of blood transfusion received by the drained group (543.3 mL) was more than that by the undrained group (367.8 mL; p = 0.0074), and similarly, TBL in the drained group (750.1 mL) was more than that in the undrained group (537.4 mL; p = 0.0067). Regarding clinical and laboratory outcomes, compared with the undrained group, the drained group had a higher VAS score on postoperative day 2 (p = 0.0216). No difference was observed between the 2 groups for morphine equivalent dosage, thigh swelling, wound infection and hematoma, hospitalization period, or total number of complications at every time point after index procedure. CONCLUSIONS:Blood transfusion requirement and TBL were higher in the drained group than in the undrained group of PFNA fixation for ITFs. In addition, the closed drainage system may have manifested no short-term benefit for wound condition postoperatively.
