Brief Summary:
The investigators found that there is inflammation in the chest drainage in patients after the Fontan operation. The investigators want to test the theory that Colchicine, an anti- inflammatory medication, can decrease the inflammation in the chest tube drainage after the Fontan operation, and can decrease the amount of time that patients having this surgery will have drainage.

Drug Information available for: Colchicine

Arm Intervention/treatment
Experimental: Colchicine
Colchicine will be given at 0.6 mg once daily for the duration of chest tube output plus 24 hours after chest tube removal with a maximum of 4 weeks duration.
Drug: Colchicine
Colchicine is an alkaloid approved in 1961 for the use in Familial Mediterranean Fever in adults and children 4 years of age or older. It has been widely used for decades in other indications, such as Gout, recurrent pericarditis, pericardial effusions and other inflammatory diseases. This drug is commercially available and is approved in children 4 years and older.




Primary Outcome Measures :
  1. Change in Cytokine concentrations in pleural fluid from patients treated with Colchicine [ Time Frame: Postoperative day 1 ; day most distal from surgery, approximately 7 days after surgery ]
    Cytokine concentrations measured by the Bio-rad Bio-Plex ProHuman Cytokine 17-plex Assay.

  2. Difference in change of Cytokine concentrations in pleural fluid patients treated with Colchicine compared to historical controls [ Time Frame: Postoperative day 1 ; day most distal from surgery, approximately 7 days after surgery ]

Secondary Outcome Measures :
  1. Cytokine concentrations as measured in postoperative Fontan patients treated empirically with Colchicine [ Time Frame: Postoperative days 1, 2, 3, 4, 7, 10, 14, 21 and 28 ]
    Particularly Cytokine concentrations of TNF-α, MIP-1βm, IL-17A, IL-8, and INF-γ, determined by the Bio-rad Bio-Plex ProHuman Cytokine 17-plex Assay

  2. Difference in Cytokine concentrations, as measured in postoperative Fontan patients treated empirically with Colchicine in comparison to a cohort of postoperative Fontan patients [ Time Frame: Postoperative days 1, 2, 3, 4, 7, 10, 14, 21 and 28 ]
    Concentrations measured by Bio-rad Bio-Plex ProHuman Cytokine 17-plex Assay

  3. Duration of pleural drainage as measured in postoperative Fontan patients treated empirically with Colchicine [ Time Frame: Date of chest tube drainage discontinuation, approximately 11 days after surgery ]
    Duration is measured in days, from date of Fontan surgery to chest tube drainage discontinuation

  4. Difference of duration of pleural drainage of two groups, in empiric treatment with Colchicine compared to a cohort of Fontan patients not treated with Colchicine [ Time Frame: Date of chest tube drainage discontinuation, approximately 11 days after surgery ]
    Duration is measured in days, from date of Fontan surgery to chest tube drainage discontinuation

  5. Hospital length of stay as measured in postoperative Fontan patients treated empirically with Colchicine [ Time Frame: Hospital discharge at study completion, approximately 2 weeks after surgery ]
    Measured in days, from date of Fontan surgery to chest tube drainage discontinuation

  6. Difference in hospital length of stay [ Time Frame: Hospital discharge at study completion, approximately 2 weeks after surgery ]
    Measured in days compared to historical controls
