Further study details as provided by Larissa University Hospital:

Primary Outcome Measures:
  • Occurrence of AF [ Time Frame: 6 postoperative days ] [ Designated as safety issue: No ]
    Every day, for the first 6 postoperative days, the investigators will record an ECG of the patient, and look after for any presence of AF

Secondary Outcome Measures:
  • Quality of analgesia [ Time Frame: 6 postoperative days ] [ Designated as safety issue: No ]
    The investigators will record the quality of analgesia, as it can be measured with VAS, for the 6 first postoperative days for all patients

Estimated Enrollment: 50
Study Start Date: December 2014
Estimated Study Completion Date: January 2017
Estimated Primary Completion Date: January 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 6 days TEA
Postoperative analgesia for the first six postoperative days with TEA and daily monitoring for arrhythmia
Other: Thoracic Epidural Analgesia (TEA)
Active Comparator: 3 days TEA and 3 days intravenous morphine
Postoperative analgesia for the first three postoperative days with TEA followed for the next three days with intravenous morphine, and daily monitoring for arrhythmia
Other: TEA followed by Intravenous morphine

Detailed Description:

THEA is considered a very effective technique of providing intra and post-operative analgesia for thoracic surgical procedure and it seems that can also be effective in reducing the incidence of postoperative AF in patients undergoing lung resection. Nevertheless the timing of stopping the epidural analgesia and its further substitution with other therapies, remains unclear.

In this study patients who are scheduled for lung resection surgery will undergo the surgery under combined general anesthesia with volatile anesthetics and thoracic epidural anesthesia.

Immediately after surgery the patients will be divided into two groups:

  • those who will receive thoracic epidural analgesia for 6 days
  • those who will receive thoracic epidural analgesia for 3 days and will then switch to intravenous morphine for another 3 days

All the patients will be monitored daily for arrythmias
