The aim of this study is to asses the blood loss in third period of labor according the method of its prophylactic. The material consist of 144 prospective and 192 retrospective cases. The blood loss is assessed visually and after that it is weighted. Up to the delivery of placenta the visually assessed blood loss is insignificantly greater than the weighted one. All cases are subdivided in three groups according the management of third period: -with methergin, with oxytocin and without uterostonic. The blood loss associated with the separation and delivery of the placenta is not different in the groups, but the early postpartum haemorrhage is significantly greater in the cases without uterostonics for the delivery of placenta. In premature labors the blood loss associated with the separation of placenta is significantly greater that in term labor.
本研究的目的是根据预防方法评估第三产程中的失血量。材料包括144例前瞻性病例和192例回顾性病例。失血量先通过目测评估，之后再称重。直至胎盘娩出，目测评估的失血量略大于称重的失血量。根据第三产程的处理方式，所有病例分为三组：使用麦角新碱组、使用缩宫素组和未使用宫缩剂组。各组中与胎盘剥离和娩出相关的失血量无差异，但在未使用宫缩剂娩出胎盘的病例中，早期产后出血明显更多。在早产中，与胎盘剥离相关的失血量明显多于足月产。
