目的探讨剖宫产术后两种镇痛方法的视觉模拟评分VAS和Bron肌力分级。方法有剖宫产手术指征、无椎管内麻醉禁忌症患者223例,随机分为镇痛方法Ⅰ组112例和方法Ⅱ组111例行硬膜外自控镇痛(PCEA)术后镇痛。方法Ⅰ组:舒贝康PCEA泵额定容量200ml、额定流量4.0ml/h、自控加药量0.5ml/15min,罗哌卡因0.125%+0.25μg/ml舒芬太尼;方法Ⅱ组:舒贝康PCEA泵额定容量100ml、额定流量2.0ml/h、自控加药量0.5ml/15min,罗哌卡因0.25%+0.5μg/ml舒芬太尼。分别于术后1、24、48h观察各组VAS评分、PCEA次数和Bron肌力分级。结果术后1、24、48h各组Bron肌力分级差异无显著性(P>0.05);24h、48hPCEA次数Ⅰ组少于Ⅱ组,差异有显著性(P<0.05),VAS评分24h、48hⅠ组低于Ⅱ组,差异有显著性(P<0.05)。结论Ⅰ组镇痛效果优于Ⅱ组,两组各时点Bron肌力分级无差别。
Objective To investigate visual analogue scale (VAS) and muscle strength classification (BEA) of two analgesia methods after cesarean section. Methods There were 223 cases of cesarean section indications and no contraindications to intraspinal anesthesia were randomly divided into two groups: 112 cases in group Ⅰ and 111 cases in group Ⅱ. Postoperative analgesia after PCEA . Method Ⅰ: Shu Beikang PCEA pump rated capacity of 200ml, the rated flow of 4.0ml / h, the amount of controlled dosage 0.5ml / 15min, ropivacaine 0.125% + 0.25μg / ml sufentanil; Beikang PCEA pump rated capacity 100ml, rated flow 2.0ml / h, the amount of controlled dosing 0.5ml / 15min, ropivacaine 0.25% + 0.5μg / ml sufentanil. The VAS score, PCEA frequency and Bron muscle strength were observed at 1, 24, and 48 h after operation. Results There was no significant difference in Bronchial muscular grading between groups at 1, 24, 48 h after operation (P> 0.05). The number of PCEA at 24h and 48h was less in group I than in group II (P <0.05) Group than in group Ⅱ, the difference was significant (P <0.05). Conclusion The analgesic effect of group Ⅰ is better than that of group Ⅱ, and there is no difference between two groups in the grade of bronchial muscle at each time point.
