Use of thopaz in patients of empyema thoracis undergoing decortication

Abstract

Introduction: The management of empyema thoracis has evolved over the years. After all lung surgeries chest drain is required, however they suffer from inter observer variability and impair mobility of the patient. However, the newer digital thoracic drain system are portable and have alarms for various situations, furthermore they eliminate inter-observer variability. One such device is Thopaz™ (Medela inc, Switzerland). We wanted to compare efficacy of Thopaz™ with our conventional intercostal chest tube drain in patients undergoing decortications for empyema thoracis. Materials and Methods: One hundred patients were enrolled in study and were randomized into conventional and thopaz group with 50 patients in each group with help of opaque envelopes. Results: Both the groups were comparable in demographic parameters. Majority of the patients in our study were children and young adults. Majority of empyema thoracis involved right side with nontubercular empyema thoracis being the most common cause of decorticartion. Patients managed with Thopaz had a significantly shorter air leak duration, shorter duration of postdecortication chest tube placement and shorter postoperative hospital stay. All postoperative complications were less in Thopaz group. Conclusions: Patients with empyema thoracis undergoing open decortications when managed with digital chest drainage system (Thopaz) experienced faster reduction in air leak, a shorter duration of chest tube placement and in hospital stay. Thopaz usage is also associated with reduction in rate of postoperative complications. We recommend that this digital chest tube drainage system is a very useful tool in armamentarium of thoracic surgeon after lung surgeries.
