Post-op Blood Loss/24 hours and total. Chest tube drainage in the first 24 hours was significantly less in TA group (median of 626 ml) than in the placebo group (median of 1040 ml) (P = 0.04). This represented about 37% decrease in the blood loss. The median total post-operative chest tube drainage was 656 ml (range 248–2105) in TA group and 1056 ml (range 210–3010) in the placebo group, which represents 32% reduction in total bleeding.
