E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The study will test the hypothesis that a continuous bilateral parasternal block with lidocaine will decrease postoperative pain after sternotomy for open cardiac surgery.
|
Studien kommer att pröva hypotesen att en kontinuerlig bilateral parasternal blockad med lidocaine kommer att minska den postoperativa smärtan efter sternotomi för öppen hjärtkirurgi.
|
|
E.2.2 | Secondary objectives of the trial |
The study will evaluate whether improved analgesia by a continuous parasternal block will increase postoperative recovery. |
Studien kommer att utvärdera om förbättrad smärtlindring genom kontinuerlig parasternal blockad kommer att förbättra den postoperativa återhämtningen. |
