Primary Outcome Measures:
  • Pain intensity [ Time Frame: 123 sec x 4 ]
    Pain was caused by Cold Pressure Test

Secondary Outcome Measures:
  • Ventilatory function [ Time Frame: 10 min x 4 ]
    Respiratory frequence (breath/min), tidal volume (mL), minute volume (L)and expiratory end-tidal carbon dioxide tension (mmHg)

  • Cognitive function [ Time Frame: 4 min x 4 ]
    Cognitive function was tested using pc-tests like Cambridge Neuropsychological Test Automated Battery (CANTAB) and Stroop-test

Enrollment: 12
Study Start Date: December 2011
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)

Experimental: Pregabalin/Remifentanil Drug: Pregabalin
hard capsule, 150 mg, 2 times, 2 days
Other Name: Lyrica
Drug: Remifentanil
50-90 min: TCI 0.6 ng/mL, 100-140 min: 1.2 ng/mL, 150-190 min: TCI 2.4 ng/mL
Other Name: Ultiva

Detailed Description:

Pain during cold pressor test (CPT) was scored at all dose levels of remifentanil on a visual analogue scale (VAS 0-100 mm). Ventilatory function was measured by spirometry registering respiratory frequency (breaths/min), minute volume (L/min) and expiratory end-tidal carbon dioxide tension (mmHg).

Side effects such as nausea and sedation were registered.
