Introduction:

In this study, we sought to investigate the association between post-operative atrial fibrillation incidence and intra-operative factors, such as estimated blood loss, operative time, and intra-operative complications, in patients who underwent robotic-assisted video-thoracoscopic pulmonary lobectomy.

Methods:
 

Prospectively collected data from 208 consecutive patients who underwent robotic-assisted pulmonary lobectomy by one surgeon for known or suspected lung cancer were analyzed. Postoperatively, 39 (18.75%) of them experienced atrial fibrillation (AF) during the hospital stay. Estimated blood loss (EBL) during operation, duration of operation, and intra-operative complications from all patients were collected and analyzed. Statistical significance (p<0.05) was determined by unpaired student’s t-test.

Results:

Eighteen out of 208 patients (8.7%) experienced intra-operative complications during the surgery. Of which, 5 of them (27.8%) experienced postoperative AF, which is a slightly higher incidence of AF than for patients without complication intra-operative complications (34 out of 190, 17.9%). In the group of patients who experienced postoperative AF, the mean and median EBL were 368ml and 200ml ,respectively, which were both higher (but not significantly, p = 0.08) than the mean and median EBL in patients without AF (266ml and 150ml, respectively). There is no significant difference in operative times between the patients with and without postoperative AF (median 225mins vs. 206mins, p=0.33).

Conclusion:

This study supported that the potential link between post-operative atrial fibrillation and intra-operative complications. Thought not significantly different, the patients who experienced postoperative AF had higher EBL and longer operative times during surgery.
