- Primary Outcome Measures
Name Time Method The primary outcome measures of this study were <br>1) the quality of pain control (numerical rating scale, NRS, at rest, with 0 = no pain, 10 = worst imaginable pain), and <br><br>2) and the intensity of motor block of the hand, assessed using the Modified Medical Research Council Scale for measuring hand muscles strength, cf. Brandsma JW, Schreuders TA: Sensible manual muscle strength testing to evaluate and monitor strength of the intrinsic muscles of the hand: a commentary. J Hand Ther 2001; 14:273-8, grade 1 = no motion / palpable muscle contraction only, grade 2 = reduced motion / no muscle resistance, Grad 3 = full motion / no muscle resistance, Grad 4 = full motion / reduced muscle resistance, Grad 5 = full motion / normal muscle resistance.<br><br>Data was assessed prior to the operation as well as 10 min, 30 min, 240 min and 1440 minutes after the operation.
- Secondary Outcome Measures
Name Time Method Secondary outcomes included the proportion of patients with considerable pain (NRS>3), dose of the opioid Piritramid in the post-anaesthesia care unit and number of Ibuprofen tablets taken in the first 24 hours. <br>Further secondary outcomes were patient satisfaction, whether patients would recommend the regional anaesthesia technique received to friends or family. Patients were asked to rank their satisfaction with pain control and were about how strongly they would recommend the regional anesthesia to friends or family, both on a 5 point Likert scale.<br>We also recorded complications.
