Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of water seal and suction after pulmonary lobectomy: a prospective, randomized trial.
The objective of the present study was to assess whether placing chest tubes on water seal after pulmonary lobectomy reduced the duration of air leak compared with suction. ⋯ Chest tubes placed on water seal after pulmonary lobectomy were generally well tolerated and safe; however, they did not reduce the duration of air leak or the incidence of prolonged air leak compared with suction.

Randomized Controlled Trial Comparative Study Clinical Trial
Beating versus arrested heart coronary revascularization: evaluation by cardiac troponin I release.
This prospective randomized study aimed to compare beating and arrested heart revascularization in patients undergoing first elective coronary artery bypass graft, with cardiac troponin I release used to evaluate myocardial injury. ⋯ The lower release of cardiac troponin I in the beating heart revascularization group indicates that conventional coronary artery bypass graft with cardioplegic arrest causes more damage to the heart than off-pump myocardial revascularization.
