RESUMEN
OBJECTIVE: To determine the level of satisfaction in terms of pain relief and comfort among patients receiving different postoperative analgesia protocols after hand surgery under regional anaesthesia in a day care unit. METHODS: Cohort study among patients after hand surgery under regional anaesthesia during two consecutive three months time periods, with patient stratification according to the expected pain level with different balanced analgesia protocols (group A: carpal tunnel, group B: other surgery without bone involvement, group C: bone surgery). A telephone survey, scoring analgesia and comfort, each with a numerical (0-10) scale was conducted on days 1 and 7. During the first period analgesia for groups A and B was the same (acetaminophen-dextropropoxyphene or acetaminophen-codeine) and group C patients were treated with acetaminophen-ketoprofen-tramadol. In the second period analgesia was reduced for group A (acetaminophen alone) and increased for group B (acetaminophen-ketoprofen-tramadol) and group C (duration increased from 3 to 7 days). RESULTS: For carpal tunnel surgery, analgesia with acetaminophen alone was efficient, (Pain scale [PS] d0=2[0-10], PS d1=1 [0-10] and PS d2-d4=0,5 [0-10]). This surgery does not elicit important pain, there is no benefit in adding other analgesics. For group B, a significant improvement in postoperative pain was observed (postoperative d1 p<0.03) with a major increase in side effects (2/57 vs 17/48 p<0.001). For group C, therapeutic changes were ineffective (PS d0=2 vs 3.5 et PS d1=3 vs 5 [NS]) and we noticed an increase in side effects (p<0.05). One third of all patients are totally satisfied on day 7, logistic regression showing the role of inefficient analgesia in late postoperative period (PS>2 between d2-d4). Between day 1 and day 7, 20% of the patients change their point of view, those who feel less satisfied on day 7 complained of a more severe postoperative pain between day 2 and 4 (p<0.001) and between day 5-7 (p<0.01). CONCLUSION: For hand surgery on day case, quality of late postoperative analgesia (day 2-day 7) is strongly related to patient's satisfaction on day 7.
