哌替啶在第1产程中的作用

The Effect of Pethidin in the First Course of Labor

随机抽取初产妇１００例，于第１产程潜伏期肌肉注射哌替啶１００ｍｇ（注射组）及同样３０例未注射哌替啶（对照组）。观察第１产程中两组产妇的表现是否安静，产程进展速度、阴道手术产率、产后出血及新生儿出生后阿氏评分等指标。结果表明：注射组１００例产妇第１产程中情绪稳定、安静、能与医务人员合作，对照组３０例中２５例因不能忍受宫缩疼痛而表现烦燥、紧张、小声呻吟或大声叫喊。两组临床表现有较大差别：注射组第１产程时间明显缩短于对照组（Ｐ＜０．０１）；阴道手术产发生率两组比较差异有高度显著性（Ｐ＜０．０１）；两组无一例发生产后出血，新生儿阿氏评分两组差异无显著性（Ｐ＞０．０５）。说明哌替啶在第１产程中使用，可迅速发挥其镇痛、镇静及欣慰感的作用，使产妇对产痛迟钝、消除紧张、保持安静、解除疼痛。并能加强宫缩力，缩短第１产程及降低阴道手术产率，有利于母婴安全。
