The Effect of Intra Operative Dexmedetomidine in Prevention of Early Postoperative Atrial Fibrillation

• Status: Recruiting

• Target enrollment: 0
• Participant gender: All

Summary

The incidence of atrial fibrillation (AF) after lung resection varies between 12% and 30% after lobectomy and 23%-67% after pneumonectomy. The average time of onset of AF after lung resection is 2-3 days. AF after pulmonary resection can cause symptoms, hemodynamic instability, and stroke.Furthermore, AF following pulmonary resection may triple the mean duration stay in the intensive care unit and increase the total length of hospital stay by 2-9 days, with an increased in associated hospitalization costs.lastly, AF after lung resection has been associated with an increased risk of mortality , although the arrhythmia is more likely to be a consequence of other associated cardiopulmonary complications, rather than the main cause of death.

our study aim to assess the role of intra operative dexmedetomidine in reduction of early postoperative atrial fibriliation in patients undergoing thoracic non cardiac surgeries.

Objectives:

1. To evaluate possible efficacy of intraoperative dexmedetomidine in reduction of postoperative atrial fibriliation in patients undergoing thoracic non cardiac surgeries

2. To determine the incidence of new-onset atrial fibrillation after thoracic non cardiac surgeries in patients given intra operative dexmedetomidine
