Fig 1 Incidence of side-effects of all patients using patient-controlled anaesthesia (n=458) on postoperative day 1 (exact numbers are given above the bars). There was no difference in the incidence of side-effects with morphine compared with piritramide.

Fig 2 Pain scores (numerical rating scale (NRS); mean (sd)) on the postoperative days 1–4 (a) during movement and (b) at rest. On postoperative day 1, pain scores both during movement (4.9 (2.3) vs 4.5 (2.2)) and at rest (2.6 (2) vs 2.2 (1.9)) were lower in the morphine group. *P<0.05 vs piritramide.

Fig 3 Piritramide concentration during storage at room temperature and at 2–8°C). With storage at 2–8°C, a slight (<5%, P<0.05) increase in piritramide concentration occurred over 40 days. Storage at room temperature was associated with a 14% increase in piritramide concentration.
