[Routine episiotomy--a five year practice at University Hospital "Majchin Dom"].

Episiotomy continues to be a frequently used procedure in obstetrics despite little scientific support for its routine use. The rationale for routine episiotomy is based on two foundation arguments: that episiotomy reduces perineal trauma and that it prevents subsequent pelvic relaxation. A careful review finds little evidence to support these arguments. Although episiotomy does decrease the occurrence of anterior lacerations, it fails to accomplish the majority of goals stated as reasons for its use. Episiotomy does not decrease damage to the perineum but rather increases it. The midline episiotomy increases the risk for third-degree and fourth-degree lacerations. Episiotomy fails to prevent the development of pelvic relaxation and its attendant complications. Rather than decreasing maternal morbidity, episiotomy increases blood loss and is related to greater initial postpartum pain and dyspareunia. The claims of a protective effect on the fetus in shortening the second stage of labor, improving Apgar scores, and preventing perinatal asphyxia have not been borne out. Efforts should be directed to determine whether episiotomy is beneficial. It is now very important to improve new birthing techniques that maintain the integrity of the perineum and do not involve surgical procedures. More trials are necessary to clarify which are the real indications to use episiotomy. Meanwhile, without the proper scientific evidence, the most correct attitude seems to be a careful use of episiotomy, with decisions on a case-by-case basis.
