In a prospective clinical investigation of 2,144 deliveries, we elucidate the indications for episiotomy and how different methods of anesthesia affect the frequency of episiotomy and the perineal problems after episiotomy compared with those after spontaneous perineal laceration. We found a significantly higher infection rate (p less than 0.001) and a longer healing period in the episiotomy group. These differences remain even if only primigravida or the indication, imminent perineal laceration, is studied. The results indicate that many women will unnecessarily suffer after an episiotomy. The patient's subjective problems are significantly increased, both immediately and at the 3-month postoperative follow-up.
在一项对2144例分娩的前瞻性临床研究中，我们阐明了会阴切开术的指征，以及与自然会阴裂伤相比，不同麻醉方法如何影响会阴切开术的频率和会阴切开术后的会阴问题。我们发现会阴切开术组的感染率显著更高（p小于0.001）且愈合期更长。即使仅研究初产妇或指征为即将发生的会阴裂伤，这些差异仍然存在。结果表明，许多女性在会阴切开术后将不必要地遭受痛苦。患者的主观问题在术后即刻和术后3个月随访时均显著增加。
