Key Words: Chest drains Pleurodesis Persistent air leak
We read with interest the paper A Prospective study of autologous Blood patch pleurodesis for persistent air leak after pulmonary resection by Loïc Lang-Lazdunski and Aman S. Coonar (Eur J Cardiothorac Surg 26 (2004) 897900) [1]. We too would endorse the use of autologous blood patch pleurodesis for persistent air leak. It is effective and economic as a treatment in this group of patients. In our unit, we use this technique after 4 days of persistent air-leak as we have found that if the air-leak has not resolved by day four, it is unlikely to do so by day 7 without further intervention. We also used to inject 5060ml of autologous blood, but with poor efficacy, unlike the authors. We now use a total of 120ml instilled once. This has resulted in close to one hundred percent resolution of air leaks and is consistent with previous studies [24].
However, we would raise one concern with regard to the methodology of performing blood patch pleurodesis. In our experience, these patients have a significant air-leak and would not tolerate the drain being clamped at all, let alone for 30min as suggested by the authors. Such patients are at risk of developing a tension pneumothorax. We would advise instead that the chest tube is rigged up on a drip stand (Fig. 1). This allows the autologous blood patch to remain within the chest cavity, but enables any air to escape, with minimal risk of developing a tension pneumothorax. We would therefore recommend this technique as an alternative to clamping.
