In the SA\u2010PCA group, patients received 0.5% ropivacaine at a rate of 2\u00a0ml\/h with a patient\u2010controlled bolus dose of 2\u00a0ml. In the IV\u2010PCA group, patients received intravenous patient\u2010controlled analgesia.

The frequency of requested bolus doses by patients in the IV\u2010PCA (19 \u00b1 19) was higher than in the SA\u2010PCA (7 \u00b1 10, <jats:italic>P<\/jats:italic> = 0.04). Rescue opioid or NSAID requirements were not different. More patients in the IV\u2010PCA (17\/30) experienced nausea than in the SA\u2010PCA (7\/30, <jats:italic>P<\/jats:italic> = 0.03). Patient satisfaction was higher in the SA\u2010PCA than in the IV\u2010PCA [6.7 (3\u201310) vs. 5.6 (0\u20138), <jats:italic>P<\/jats:italic> = 0.04]. The mean total venous plasma concentration of ropivacaine at 8 and 24 h was below the maximum tolerated venous plasma concentration, and symptoms of systemic toxicity were not noted during 48 h in the
