PURPOSE: The aim of this clinical study is to evaluate the efficacy of DigiVentTM, a digital drainage system that measures the air leakage and pleural pressure variations and can show those measurements over time.
METHODS: This prospective study included 20 evaluable cases on 24 consecutive cancer resected patients for primary or secondary malignancies from March to April 2008. There were 13 lung resections: 3 lobectomies, 10 sublobar resections. Moreover, there were 7 video-assisted thoracoscopic procedures: 6 partial pleurectomies plus talcage, but 1; the remaining patient had a thoracectomy plus a running suture of a parenchimal injury. Two patients (10 %) had previously a lung resection procedure on the same lung. All the patients underwent pre and post-operatively chest X-ray, pulmonary functional tests, blood gas analyses, and requested the grade of benefit.
RESULTS: The results showed excellent clinical performance. The Digital System revealed an air leakage in 4 cases (range 300–730 ml/min) in a period ranging from 4 to 9 days. The curve flow revealed a lobar atelectasis in 2 patients as a wide swinging. Moreover, we could identify a chest tube malfunction in 2 cases (1 complete collapse and 1 obtruction) as an absent swinging curve showing an inexact endopleural pressure. The collection chamber of the DigiVentTM was changed for the low capacity until to 2000 ml in 3 cases. There was a comparable result between the post-operative chest X-ray and the absence of air leakage as showed by digital display; that permitted a timely chest drain removal. The mean hospital stay was 4.5 days, range 4–9 days.
CONCLUSION: The ability to save data and record curves for the post-operative period could be an advantage for the clinical team.
CLINICAL IMPLICATIONS: The safe and simple use of the Digital Drain System efforts the compliance of the nurse too. The better patients and medical implication was the control and the reduction of the hospital time.
