![]() The foetus and mother are usually not affected apart from maternal anxiety due to prolonged labour.Uterine contractions are infrequent, weak and of short duration.Secondary inertia: inertia developed after a period of good uterine contractions when it failed to overcome an obstruction so the uterus is exhausted.Primary inertia: weak uterine contractions from the start.The presenting part is not fitting in the lower uterine segment leading to absence of reflex uterine contractions. Malpresentations, malpositions and cephalopelvic disproportion.Myomas of the uterus interfering mechanically with contractions.Developmental anomalies of the uterus e.g.Hormonal due to deficient prostaglandins or oxytocin as in induced labour.Nervous and emotional as anxiety and fear.Unknown but the following factors may be incriminated: The uterine contractions are infrequent, weak and of short duration. Obstructed labour should be properly treated otherwise the thinned lower uterine segment will rupture.Clinical picture: is that of obstructed labour with impending rupture uterus (see later).The Bandl’s ring is seen and felt abdominally as a transverse groove that may rise to or above the umbilicus.It is the rising up retraction ring during obstructed labour due to marked retraction and thickening of the upper uterine segment while the relatively passive lower segment is markedly stretched and thinned to accommodate the foetus.Pathological Retraction Ring (Bandl’s ring) It is a line of demarcation between the upper and lower uterine segment present during normal labour and cannot usually be felt abdominally. Episiotomy: to avoid perineal lacerations and intracranial haemorrhage.Įxamine the mother and foetus for injuries.ĮXCESSIVE UTERINE CONTRACTION AND RETRACTION.Tocolytic agents: as ritodrine (Yutopar) may be effective.Inhalation anaesthesia: as nitrous oxide and oxygen is given to slow the course of labour. ![]() Patient who had previous precipitate labour should be hospitalized before expected date of delivery as she is more prone to repeated precipitate labour.
