I haven't seen any new proposals from the BTS yet but agree a "small" (10-14 G) drain for pneumothoraces is ideal, if aspiration has failed. I placed a 12 G drain after aspiration of a large pneumothorax failed due to persisting air leak this week, and on check xray the drain was coiled 360 degrees in the pleural space but still draining air well...they appear to have a reinforcing strip down one side... Small seldinger style drains should be I feel the drain of choice for simple pneumothoraces. What is the BTS going to recommend, does anyone know? Marten Howes Preston
