Postoperative Analgesia Impact of Narcotic Free Anesthesia (PAINFree)
|ClinicalTrials.gov Identifier: NCT01544959|
Recruitment Status : Active, not recruiting
First Posted : March 6, 2012
Last Update Posted : October 27, 2016
The first hypothesis of the study is that substituting fentanyl by esmolol and metoprolol during general anesthesia for patients undergoing mastectomy will result in less pain and less narcotic consumption in the recovery room. The investigators will also verify the impact of that substitution on nausea and vomiting, on the time spent in the recovery room and on chronic postsurgical pain (3 and 6 months).
Finally, the investigators will see the impact on breast cancer recurrence 5 years after the surgery.

|Active Comparator: fentanyl||
Use of esmolol and metoprolol compared to use of fentanyl for hemodynamic control during general anesthesia. At induction, fentanyl (2 mcg/kg) is replaced by esmolol (1 mg/kg). During the case, with a standardised anesthesia, response to surgical stimulation will be medicated either by fentanyl (50 mcg aliquot) or metropolol (2.5 mg), for a maximum of 6 doses. After this, fentanyl will be given unblindly.
Instead of narcotics (fentanyl), esmolol and lopressor are being used for hemodynamic control
Drug: beta-blocker (esmolol, metropolol)
esmolol is used at induction and lopressor during surgery instead of fentanyl in response to surgical stimulation.
- Postoperative consumption of narcotic in recovery room [ Time Frame: Immediately after surgery ]
- Pain level in recovery room [ Time Frame: immediately after surgery ]
- Occurence of nausea and vomiting in the recovery room [ Time Frame: immediately after surgery ]
- Time spent in recovery room [ Time Frame: immediately after surgery ]
- Chronic post-surgical pain [ Time Frame: 3 and 6 months ]
- Reccurence of breast cancer [ Time Frame: 5 years ]
