Background The optimal choice of chest tube size for the treatment of pleural infection is unknown, with only small cohort studies reported describing the efficacy and adverse events of different tube sizes. Methods 405 patients with pleural infection were prospectively enrolled into a multi-centre study investigating the utility of fibrinolytic therapy. The combined frequency of death and surgery, and secondary outcomes (hospital stay, change in chest radiograph and lung function at 3 months) were compared in patients receiving chest tubes of differing size (chi squared, t-test and logistic regression analyses as appropriate). Pain was studied in detail in 128 patients. Results There was no significant difference in the frequency with which patients either died or required thoracic surgery in patients receiving chest tubes of varying size (<10F number dying or needing surgery 21/58 (36%), size 10-14F 75/208 (36%), size 15-20F 28/70 (40%), size >20F 30/69 (44%); (chi(2)(trend) 1df = 1.21, p = 0.27), nor any difference in any secondary outcome. Pain scores were substantially higher in patients receiving (mainly blunt dissection inserted) larger tubes (<10F, median pain score 6, (range 4 to 7); 10-14F 5, (4 to 6); 15-20F 6, (5 to 7); >20F 6, (6 to 8); chi(2), 3df = 10.80, p=0.013, Kruskal-Wallis chi(2)(trend) 1df = 6.3, p = 0.014). Conclusions Smaller, guide-wire inserted chest tubes cause substantially less pain than blunt dissection inserted larger tubes, without any impairment in clinical outcome in the treatment of pleural infection. These results suggest that smaller size tubes may be the initial treatment of choice for pleural infection and randomized studies are now required.
