The effect of an intraumbilical prostaglandin (PG) F2 alpha injection on the third stage of normal labor was studied in 54 normal, laboring women at term. Either 1 mg of PGF2 alpha diluted to 20 mL in normal saline (27 women) or 20 mL of normal saline alone (27 women) was injected into the umbilical vein immediately after delivery using a randomized, double-blind protocol. The mean (+/- SD) duration of the third stage was 7.31 +/- 6.37 minutes in the PGF2 alpha patients and 8.94 +/- 7.10 in the normal saline patients. Intraumbilical PGF2 alpha did not influence the third stage of normal labor.
对54名足月正常分娩的妇女研究了脐内注射前列腺素（PG）F2α对正常分娩第三产程的影响。采用随机双盲方案，在分娩后立即将1mg PGF2α用生理盐水稀释至20mL（27名妇女）或仅20mL生理盐水（27名妇女）注入脐静脉。PGF2α组第三产程的平均（±标准差）持续时间为7.31±6.37分钟，生理盐水组为8.94±7.10分钟。脐内注射PGF2α对正常分娩的第三产程没有影响。
