Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Secondary Objective: Cumulative 8-hourly NRS after 72 hours. Postoperative NRS every 8 hours for 72 hours. Postoperative NRS in ambulation twice daily for 72 hours. Postoperative recovery according to PQRS at 72 hours, 1 week and 3 months compared to preoperative values. Time until able to perform activities of daily living. Time to eat and drink. Time to walk unaided. Time to GI-function. Day of discharge and discharge time Pre- and postoperative spirometry Plasma levels of stress markers 1, 12 and 36 hours postoperatively compared to preoperative values;Primary end point(s): Cumulated intravenous PCA morphine consumption at 72 hours.;Timepoint(s) of evaluation of this end point: Evaluation of rescue analgesic requirement at 72 hours.;Main Objective: To test the hypothesis that the addition of sufentanil and epinephrine to levobupivacaine in continuous paravertebral block will increase its analgesic potency, resulting in better pain relief and enhanced recovery after Video-Assisted Thoracoscopic Surgery despite the lower total levobupivacaine dose administered. | — |
