Open-Label Randomized Controlled Study of a Disposable Dry Seal Chest Drainage System for Safety and Efficiency in...

Lobectomy, a cornerstone in the treatment of various thoracic tumors, often requires postoperative chest drainage to prevent complications such as pneumothorax and pleural effusion. Traditional water-seal drainage systems have limitations, including inconvenience and restricted patient mobility.

This study investigated the safety and efficiency of a disposable dry seal chest drainage system compared to the traditional water-seal system in lobectomy patients. An open-label randomized controlled trial with trial registration number NCTO6410716 was conducted, including 82 patients undergoing elective three-port thoracoscopic lobectomy. The study assessed postoperative pain, functional recovery, complications such as DVT, and nursing workload.

The results showed that the disposable dry seal chest drainage system significantly reduced nursing workload (p < 0.001) and improved patient mobility, with patients in the experimental group having significantly higher finger oxygen saturation levels on postoperative day 1 (p = 0.01) and day 2 (p < 0.001) compared to the control group. The incidence of DVT during the hospital stay was also lower in the experimental group (p = 0.032). Although no significant improvement in postoperative pain scores was observed, the improved functionality and reduced nursing workload suggest potential benefits for patient care and resource management.

This study provides valuable insights into the potential advantages of the new drainage system and its alignment with enhanced recovery after surgery (ERAS) protocols, supporting its use as a superior option in postoperative chest drainage management for lobectomy patients.
