[Preventive digitalis therapy in open thoracotomy].
Prophylactic digitalization is still recommended after open lung surgery in order to prevent cardiac arrhythmias in the postoperative period. Since a beneficial effect of this potentially harmful medication is only poorly documented, we conducted a prospective randomized trial. Patients undergoing elective open lung surgery were divided into two groups one of which received digoxin postoperatively, the other not. Randomization was performed independently in three groups with regard to the extent of surgery, i.e. pneumonectomies in patients of any age, (bi-)lobectomies in patients > 50 and other (less extended) operations in patients > 60. Patients who were either too young for either group or who had already taken digoxin before surgery were followed separately. Monitoring was performed continuously in the ICU and conventional ECG was registered after 24, 48 and 72 hours and weekly until dismission.--Cardiac arrhythmias are very frequent in the early postoperative period with a maximum between the third and the fifth postoperative day. Any kind of arrhythmias were present in 19 of 30 patients (63%) compared to 14 of 35 patients (40%) in the control group. Symptomatic arrhythmias that needed treatment occurred in 11.4% of the control group, but in 33.3% of the patients with prophylactic digitalization. We therefore conclude that a general prophylactic digitalization after open lung surgery is not indicated, but that arrhythmias should be treated individually.
