OG14.1 | Obstructed Labour — Summary & Reflection

KEY TAKEAWAYS

Obstructed labour is a mechanical failure of descent of the presenting part despite adequate contractions, most commonly due to contracted pelvis, fetal macrosomia, or malpresentation. It is clinically recognised by the combination of prolonged non-progressive labour, Bandl's pathological retraction ring (visible groove on the abdomen at the upper-lower uterine segment junction, rising toward the umbilicus as obstruction worsens), grade +++ caput and moulding on vaginal examination, and fetal distress. The partograph is the essential intrapartum tool: cervicograph crossing the action line (4 hours right of the alert line) demands an immediate management decision. Management is a medical emergency: establish IV access, catheterise, resuscitate with fluids, send blood for crossmatch, start antibiotics if infection is suspected, and proceed to emergency LSCS without delay. Oxytocin augmentation in the presence of obstruction is absolutely contraindicated — it adds force against an impassable barrier and causes uterine rupture. Prevention rests on universal partograph use, trained birth attendance, early identification of at-risk women antenatally, and functioning referral chains.

REFLECT

Think about a labour ward scenario from your clinical posting where a woman's progress was being monitored. Was the partograph being used? Was it completed correctly? If the cervicograph crossed the action line, was there a clear plan documented? What barriers exist in your clinical setting that might delay recognition or response to obstructed labour? How would you, as a future clinician, ensure that every woman you attend in labour has a partograph started from active phase and acted upon at the action line? Reflect on the systems-level and individual clinical skills dimensions of this problem.
