The effect of closed thoracic drainage site on efficacy and postoperative complications in patients with spontaneous pneumothorax
Objective To explore the influence of closed thoracic drainage site on efficacy and postoperative complications in patients with spontaneous pneumothorax.Methods Two hundred and eighteen patients with spontaneous pneumothorax in our hospital were selected.The patients were classified into an observation group and a control group based on area randomization method,109 in each group.In the observation group,thoracic closed drainage was performed in the third intercostal space of the anterior axillary line.In the control group,closed thoracic drainage was performed in the second intercostal space of the midclavicular line.The clinical related indicators and complications were compared between the two groups.The lung function and arterial blood gas were measured before and after 7 days of surgery.The pain degree estimated by Visual Analogue Scale(VAS)was compared before and after 6,12,24,48 and 72 hours of surgery.Results The incidence of complications was obviously lower in the observation group(P＜0.05).After 7 days of surgery,there was no significant difference in the lung function and arterial blood gas indicators between the two groups(P＞0.05).The VAS scores in the observation group at 6,12,24 and 48 hours after surgery were significantly lower compared to the control group(P＜0.05).No obvious differences were shown in VAS score and clinical indicators between groups after 72 hours of surgery(P＞0.05).Conclusions Both closed thoracic drainages in the third intercostal space of the anterior axillary line and the second intercostal space of the midclavicular line have a good therapeutic effect on spontaneous pneumothorax.Both sites have similar efficacy.However,the second intercostal space of the midclavicular line has a higher risk of complications and more serious pain.
