The Use of Subcutaneous Hemovac Drain after Open Heart Surgery with Sternotomy

Background: This study investigated the effect of subcutaneous Hemovac drain use on sternal wound complications in patients with a body mass index (BMI) ≥30 kg/m2 undergoing open heart surgery through median sternotomy. Methods: This retrospective study included a total of 120 patients (74 males, 46 females) with a BMI ≥30 kg/m2 who underwent open heart surgery through median sternotomy between January 2021 and January 2024. The mean age was 60.36 ± 11.31 years (range, 18–80 y). After median sternotomy, a Hemovac drain was placed subcutaneously in the study group (n = 60) and in controls no Hemovac drain was placed (n = 60). Durations of hospital stay, types of surgery, sternal wound complications, and preoperative, intraoperative, and postoperative data were compared between the two groups. Results: The duration of hospital stay (p = 0.018; p < 0.05), the rate of sternal wound complications (p = 0.001; p < 0.01), the rate of superficial sternal complications (p = 0.001; p < 0.01), and the need for antibiotics in superficial infections (p = 0.001; p < 0.01) were significantly lower in cases with a Hemovac drain compared to those without. Conclusion: Subcutaneous placement of a Hemovac drain after open heart surgery is a simple, easily applicable, and effective method that reduces sternal wound complications, and hospital stay in obese patients.
