Polyglycolic acid (PGA) sutures and traditional catgut were compared in 190 patients undergoing episiotomy. Each group was also randomly allocated to a double blind comparison of therapy with oral proteolytic enzymes (Chymoral) and placebo. The combination of Chymoral and polyglycolic acid sutures was shown to reduce the level of pain, assessed subjectively, and there was a significant reduction in analgesic requirements in the Chymoral/PGA group.
对190例行会阴切开术的患者比较了聚乙醇酸(PGA)缝线和传统肠线。每组还被随机分配进行口服蛋白水解酶(Chymoral)与安慰剂治疗的双盲比较。结果显示,Chymoral与聚乙醇酸缝线联合使用可降低主观评估的疼痛程度,且Chymoral/PGA组的镇痛需求显著减少。
