Outcome Measures

Primary Outcomes (1)

  • Mean VAS Pain (Visual Analogue Scale)at Rest (0-100 mm)

    The visual analogue scale (VAS) was used for registration of the pain intensity at rest. The score ranges from 0-100, where 0 means no pain and 100 means maximal pain. Higher values represent a worse outcome.

    120 minutes after surgery

Secondary Outcomes (1)

  • Morphine (Opioid) Consumption Cumulated

    240 minutes

Study Arms (2)

Pregabalin

ACTIVE COMPARATOR

150 mg Pregabalin per orally about one hour before surgery

Drug: pregabalinDrug: morphine

Placebo

PLACEBO COMPARATOR

One capsule of saccharose (placebo) was administered orally about one hour before surgery.

Drug: PlaceboDrug: morphine

Interventions

capsule 150 mg x 1 per orally one hour before surgery

Pregabalin

One capsule of saccharose (placebo) was administered about one hour before surgery

Placebo

All patients were equipped with a PCA (patient controlled analgesia) for 24 hours after surgery. The sum of morphine used was registered (milligram).

PlaceboPregabalin
