Introduction: To explore the impact of intrapericardial and infracardiac drains on pericardial effusions in cardiac surgery.

Materials and methods: Patients undergoing coronary artery bypass grafting were randomized into two groups. At the end of the intervention, an intrapericardial and infracardiac Blake drain was placed in patients in group 1 (n = 97), and an intrapericardial and infracardiac semirigid drain was placed in patients in group 2 (n = 105). In addition, a semirigid drain was placed into mediastinum in all cases. The amount of drainage was calculated at six different time points postoperatively: postoperative 0 to 2 h, postoperative 2 to 4 h, postoperative 4 to 6 h, postoperative 6 to 12 h, postoperative 12 to 24 h, and postoperative 24 to 48 h. The amount of pericardial effusion was estimated by transthoracic echocardiography after the drains were removed.

Results: In all measurements, the amount of drainage from intrapericardial Blake drains was higher, the total amount of drainage being equal to 330.7 ± 29.4 mL and 193.2 ± 19.6 mL in the Blake drain and semirigid drain groups, respectively (p = 0.000) [mean ± SD]. When the drains were removed, the volume of pericardial effusion was 3.86 ± 0.76 mm in Blake drain group and 7.59 ± 1.16 mm in semirigid drain group (p = 0.000). The incidence of postoperative atrial fibrillation was 11.3% in the group with Blake drains, and 23.8% in the group with semirigid drains (p = 0.016).

Conclusion: The more effective drainage obtained with infracardiac Blake drains compared to semirigid drains helps to reduce the amount of postoperative pericardial effusion and the risk of atrial fibrillation.

Key Words: atrial fibrillation • Blake drain • pericardial effusion
