Ventouse, also known as vacuum-assisted vaginal delivery or vacuum extraction (VE), is a method to assist delivery of a baby using a vacuum device. It is used in the second stage of labour if it has not progressed adequately. It may be an alternative to a forceps delivery and caesarean section. It cannot be used when the baby is in the breech position or for premature births. The use of VE is generally safe, but it can occasionally have negative effects on either the mother or the child.〔(eMedicine - Vacuum Extraction : Article by Christian S Pope, DO ) Retrieved December 16, 2006〕The term comes from the French word for "suction cup." ==Indications== There are several indications to use a vacuum extraction to aid delivery: *Maternal exhaustion *Prolonged second stage of labor *Foetal distress in the second stage of labor, generally indicated by changes in the foetal heart-rate (usually measured on a CTG) *Maternal illness where prolonged "bearing down" or pushing efforts would be risky (e.g. cardiac conditions, blood pressure, aneurysm, glaucoma). If these conditions are known about before the birth, or are severe, then an elective caesarean section may be performed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ventouse」の詳細全文を読む スポンサード リンク
