![]() The results of this study suggest that flutter valve drainage system is a safe and feasible alternative in managing postoperative air leaks and haemorrhage after lung surgery other than pneumonectomy if air leaks are not extremely massive. The medical device manufacturer agreed to pay 62 million to resolve charges that it violated the books and records and internal. The results of this study suggest that flutter valve. The mean length of hospitalization in the surgical ward was 3.6 (SD +/- 2.7) and 4.1 (SD +/- 4.4) days respectively (difference -0.5, 95% CI -2.5 to 1.4). The mean length of hospitalization was 16.3 (SD +/- 20.9) days and 18.7 (SD +/- 27.0) respectively (difference -2.4, 95 CI -16.1 to 11.3). In the conventional underwater seal device group the mean drainage time was 2.6 (SD +/- 2.0) days and in the flutter valve drainage bag group the mean drainage time was 3.3 days (SD +/- 4.0) difference -0.8, 95% confidence interval (CI) -2.4 to 0.9. ![]() Following withdrawal of four patients from the study, 55 patients were evaluated (31 patients in the underwater seal device group and 24 patients in the flutter valve drainage bag group). The purpose of the present study was to compare the use of a conventional underwater seal device with suction and a flutter valve drainage bag for pleural drainage after lung surgery.Īltogether 59 patients undergoing elective lung surgery except pneumonectomy between February 2001 and April 2002 were prospectively randomized to receive postoperative pleural drainage by 28F chest tube(s) attached to underwater seal device placed on negative pressure of 15 cm of water or flutter valve drainage bag. ![]()
