Abstract
Introduction: Thoracic injuries are prevalent in polytrauma patients, with road traffic accidents being a major cause. In India alone, over 400,000 people were injured in such accidents in 2022. Rib fractures, haemothorax, and pneumothorax are common chest injuries, often managed with tube thoracostomy. While standard procedures for chest tube placement are established, consensus on post-insertion management, particularly regarding negative pleural suction, is lacking. Research on this topic mostly pertains to planned thoracotomies rather than trauma cases. This study seeks to compare outcomes of slow negative suction versus conventional drainage in blunt or penetrating thoracic trauma.
Methods: This single-centre, open-label, randomized controlled trial in a western Indian hospital from Jan 2021 to June 2022 included adult patients with thoracic trauma requiring intercostal drainage tubes. Patients needing emergency thoracotomy, mechanical ventilation, or bilateral chest tubes were excluded. Sample size (n = 64) was calculated based on prior studies. Patients were randomly assigned to experimental (slow negative pleural suction) or control (conventional water seal drainage) groups. Both groups received standard care. Primary outcome was time to chest tube removal; secondary outcomes included hospital stay length, complications, and need for further intervention. Data were analysed using SPSS. Significance was set at p < 0.05.
Results: During the study 64 patients were randomised into experimental (n = 32) or conventional (n = 32) groups. Most of the patients were males (88 %, n = 56). Both groups had similar baseline characteristics. Experimental group patients had shorter median chest tube duration (3 [IQR 2-3.75] vs. 5 [3-8.75] days, p < 0.001) and hospital stay (5 [4-8.75] vs. 10 [6-16.75] days, p = 0.004). No discomfort was reported with slow continuous negative pleural suction. Mortality was 1 (3 %) in the experimental group vs. 2 (6 %) in the conventional group. Four patients suffered retained haemothorax, with only one occurrence in the experimental group (3 %).
Conclusion: Application of slow continuous negative pleural suction to chest tubes in patients of thoracic trauma can decrease the chest tube duration and the hospital stay. This study ought to be followed up with multicentric randomised clinical trials with larger sample sizes to better characterise the effects of slow continuous negative pleural suction.
