E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Total morphine consumption, other than the patients usual opioid use, 0-24 hours postoperatively, administered on as patient-controlled analgesia (PCA, bolus 2.5 mg, lockout 10 minutes) |

E.2.2 | Secondary objectives of the trial |
Pain score during active mobilisation, measured on a visual analogue scale (VAS), defined ad a standarised movement from recumbent position to sitting on the bedside at 2, 6, 12, 18 and 24 hours postoperatively, the worst pain from the movement is registered. Endpoint is AUC-VAS-mob (2-24 t) calculated from these measurements. Pain score during rest (VAS), at 2, 6, 12, 18 and 24 hours postoperatively. Endpoint is AUC-VAS-mob (2-24 t) calculated from these measurements. Degree of nausea 0-24 hours at time 2, 6, 12, 18 og 24 hours postoperatively. Number of episodes vomiting 0-24 hours, registered in periods 0-2, 2-6, 6-12, 12-18, 18-24 hours postoperatively. Use of ondansetron during the period 0-24 hours postoperatively . Degree of sedation 0-24 hours, at time 2, 6, 12, 18 og 24 hours postoperatively. Hallucinations and nightmares 0-24 hours postoperatively. Chronic pain and daily use of opioids assessed by questionnaire 6- and 12 months postoperatively.

Smertescore under aktiv mobilisation, målt på visuel analog skala (VAS), defineret ved standardiseret bevægelse fra liggende stilling til siddende på sengekanten til tiden 2, 6, 12, 18 og 24 timer postoperativt, den værste smerte ved bevægelsen registreres. Endpoint er AUC-VAS-mob (2-24 t) beregnet på basis af disse smertemål. Smertescore i hvile (VAS) til tiden 2, 6, 12, 18 og 24 timer postoperativt. Endpoint er AUC-VAS-hvile (2-24 t) beregnet på basis af disse smertemål. Graden af kvalme 0-24 timer, målt til tiden 2, 6, 12, 18 og 24 timer postoperativt. Antal af opkastninger 0-24 timer, registreret i perioderne 0-2, 2-6, 6-12, 12-18, 18-24 timer postoperativt. Forbrug af ondansetron i perioden 0-24 timer postoperativt. Graden af sedation 0-24 timer, målt til tiden 2, 6, 12, 18 og 24 timer postoperativt. Hallucinationer og mareridt 0-24 timer postoperativt. Kroniske smerter og fast forbrug af opioider vurderes ved et valideret spørgeskema 6- og 12 måneder postoperativt |
