[Immediate postoperative arrhythmias follwing pneumonectomy for lung cancer].
Immediate postoperative arrhythmias after pneumonectomy for non small cell lung cancer is a serious complication. Frequency is estimated 10 to 28% of all patients. The goal of this study is to evaluate the incidence of this complication in our experience, preoperative risk factors, therapeutic implications and short outcome. 132 consecutive patients underwent pneumonectomy for lung cancer. We retrospectively studied this series of which 29 patients developed arrhythmias postoperatively. Mean age was 58 years (48 to 79), 16 patients were older than 65 years. Seven patients had medical history of either myocardial infarction or hypertension. Arrhythmias appeared post-operatively on days 1 and 2 six times, days 3 ans 4 ten times, days 5 to 6 six times and days 7 to 10 twice. The trouble consisted in atrial fibrillation in 18 patients, atrial associated with ventricular premature beats in 11 patients. Antiarrhythmic medication (amiodarone) was started as soon as the trouble was confirmed by EKG in all cases. Normalization was obtained in 27 patients (95%). One patient remained dysrrhythmic in spite of treatment. One death occurred on day 4 postoperatively. The mean hospitalisation stay was 10 days.


CONCLUSIONS
Cardiac arrhythmia in the immediate postoperative course is not rare. Early diagnosis in patients at risk followed by adequat treatment is necessary to avoid haemodynamic storm in these quite fragile patients. Amiodarone is the treatment of choice.
