Did a placenta problem during pregnancy or birth cause serious harm — and was it managed properly?
Identify risk factors early — prior caesarean, low-lying placenta, bleeding, or abnormal growth
Order appropriate imaging — ultrasound to confirm placental position and function
Monitor mother and baby closely — escalate care if bleeding, pain, or fetal distress develops
Plan and execute delivery safely — including emergency caesarean if placenta blocks the birth canal or separates
Manage third stage of labour — confirm full placental delivery and control any bleeding
If any step was skipped or delayed, and that failure caused harm to the mother or baby, the clinical team may have breached their duty of care.
Understanding placental complications: what normally happens
The placenta is an organ that grows inside the uterus during pregnancy. It connects the mother’s blood supply to the baby, delivering oxygen and nutrients. After the baby is born, the placenta also delivers — this is called the third stage of labour.
Several things can go wrong with the placenta. Each has a different name and a different set of risks. Healthdirect Australia provides plain-English information about placental conditions for patients and families.
Placenta praevia: The placenta sits low in the uterus, partially or fully covering the cervix. This blocks the birth canal and can cause severe bleeding.
Placental abruption: The placenta separates from the uterine wall before the baby is born. This cuts off the baby’s oxygen supply and causes heavy maternal bleeding.
Placenta accreta spectrum: The placenta grows too deeply into the uterine wall. Removing it after birth can cause life-threatening haemorrhage — that is, extreme blood loss.
Retained placenta: The placenta does not fully deliver after the baby is born. This can cause serious infection and haemorrhage.
Placental insufficiency: The placenta does not function well enough to support the baby’s growth. This can cause restricted growth, oxygen deprivation, and stillbirth.
Proper care means identifying which condition is present, monitoring it throughout pregnancy, and planning delivery accordingly. Clinicians who know a patient has placenta praevia, for example, must plan a caesarean section well in advance. Waiting until bleeding begins is not acceptable practice.
When things start to go wrong
Some warning signs appear gradually. Others arrive suddenly and demand an immediate response. Knowing what the warning signs are helps you understand whether the clinical team should have acted sooner.
Warning signs that should have prompted urgent clinical action:
• Painless vaginal bleeding in the second or third trimester — a classic sign of placenta praevia
• Sudden, severe abdominal pain with or without bleeding — a key sign of placental abruption
• Reduced fetal movement — may indicate the baby is not receiving enough oxygen through the placenta
• Abnormal CTG (cardiotocograph) readings — a CTG monitors the baby’s heart rate during labour
• Uterus that feels hard, rigid, or tender to touch — associated with abruption
• Placenta not delivered within 30 minutes of birth — the clinical threshold for retained placenta
• Heavy bleeding after delivery that does not slow — a sign of postpartum haemorrhage linked to placental problems
Each of these signs carries a specific clinical meaning. A competent clinician recognises them and responds. Dismissing bleeding as “normal spotting” or failing to order an ultrasound after a patient reports reduced movement are examples of care falling below the expected standard.
A common pattern — where care can break down
Placental complications involve a range of failure points. The Australian Commission on Safety and Quality in Health Care has identified communication failures, inadequate monitoring, and delayed escalation as recurring problems in maternity care. Below are the most common patterns seen in placenta-related harm.
Failure to diagnose placenta praevia before labour
Routine ultrasounds during pregnancy should identify a low-lying placenta. When a clinician fails to order a follow-up scan, misreads imaging results, or does not communicate the diagnosis to the patient, the mother may arrive at labour without a safe delivery plan. Attempting a vaginal birth with an undiagnosed placenta praevia can cause catastrophic haemorrhage.
Delayed response to placental abruption
Abruption is a time-critical emergency. The baby loses oxygen rapidly when the placenta separates. Clinicians who delay ordering an emergency caesarean — or who misread CTG abnormalities as minor — can cause permanent brain injury or death. Every minute of delay increases the risk of irreversible harm.
Failure to plan for placenta accreta
Women with prior caesarean sections face a higher risk of placenta accreta — where the placenta embeds too deeply into the uterine wall. Clinicians who do not identify this risk before delivery may attempt manual removal of the placenta, triggering uncontrollable bleeding. Proper care requires specialist planning, a surgical team, and blood products ready before delivery begins.
Retained placenta left unmanaged
After birth, the clinical team must confirm the placenta has delivered completely. Fragments left inside the uterus cause infection and haemorrhage. Standard practice requires the midwife or obstetrician to inspect the placenta and act within a defined timeframe if delivery does not occur. Failing to do so — or discharging a patient before confirming complete delivery — is a serious departure from accepted practice.
Placental insufficiency missed during antenatal care
Clinicians who fail to monitor fetal growth, ignore abnormal Doppler flow studies, or dismiss a mother’s reports of reduced movement may miss a failing placenta. Babies deprived of oxygen in the womb can suffer brain damage, organ failure, or stillbirth — outcomes that earlier intervention may have prevented.
Why this matters legally
Every clinician who treats a patient owes that patient a duty of care — a legal obligation to provide treatment that meets the standard of a competent professional in the same field. Not every bad outcome means negligence occurred. Pregnancy carries inherent risks, and some complications arise even with excellent care.
But the law draws a clear line. When a clinician’s actions — or failures to act — fall below the standard a reasonable obstetrician, midwife, or GP would have met, and that failure causes harm, the law may treat it as negligence. For more information about how this standard applies in maternity cases, see Reframe Legal — Medical Negligence.
The key question is not whether something went wrong. The question is whether the clinical team did what a competent team would have done — and whether doing it properly would have changed the outcome.
A placental abruption that occurred suddenly and without warning signs, where the team responded immediately and appropriately, but the baby still suffered harm
A clinician who knew about placenta praevia but did not plan a caesarean, and the mother then suffered life-threatening haemorrhage during attempted vaginal delivery
This is a general educational framework only. Each case is assessed on its individual facts.
When placental complications may amount to medical negligence
The NSW Civil Liability Act 2002 sets out the legal framework for negligence claims in this state. In plain terms, it means a court will ask whether a reasonable clinician in the same situation would have acted differently — and whether acting differently would have prevented the harm.
Placental complications may give rise to a negligence claim in situations like these:
- An ultrasound identified a low-lying placenta, but no follow-up scan was ordered and no caesarean was planned — and the mother bled severely during labour
- A mother reported reduced fetal movement repeatedly, but no clinician ordered further investigation — and the baby was later stillborn
- A CTG showed signs of fetal distress during labour, but the team delayed the decision to perform a caesarean — and the baby was born with brain damage
- The placenta was not fully removed after birth, the mother developed sepsis — that is, a life-threatening infection — and no clinician had checked for retained fragments before discharge
- A woman with a prior caesarean scar was not assessed for placenta accreta, and the delivery team was unprepared for the haemorrhage that followed
In each scenario, the question is the same: did the clinical team do what a competent team would have done? If the answer is no, and harm followed, the law may recognise a claim.
When harm becomes long-term or permanent
Placental complications can cause harm that lasts a lifetime — for the baby, the mother, or both. Understanding the full scope of that harm matters when assessing what a legal claim might cover.
Harm to the baby
Oxygen deprivation caused by placental abruption or insufficiency can result in hypoxic-ischaemic encephalopathy — brain damage caused by lack of oxygen. Babies who survive may live with cerebral palsy, intellectual disability, epilepsy, or developmental delays. Some require full-time care for the rest of their lives. Others do not survive.
Harm to the mother
Severe haemorrhage from placenta praevia, abruption, accreta, or retained placenta can require emergency hysterectomy — surgical removal of the uterus — ending the mother’s ability to have more children. Blood transfusions, intensive care admissions, and prolonged recovery are common. Some mothers develop post-traumatic stress disorder, depression, or chronic pain.
Financial and practical consequences
Families caring for a child with permanent disability face enormous costs — therapy, equipment, home modifications, and lost income when a parent reduces work to provide care. Mothers who suffer serious physical harm may lose the ability to work for months or permanently. These financial consequences compound over decades and form a significant part of any compensation claim.

What compensation can cover in placental complication cases
NSW law allows compensation for a range of losses when negligence causes harm. This includes pain and suffering, lost income, the cost of ongoing medical treatment, and the cost of care — both professional care and care provided by family members.
In cases involving a child with permanent disability, courts also consider the cost of future care across the child’s entire lifetime. These claims can be substantial.
| Level of harm | Typical compensation range |
|---|---|
| Moderate injury | $50,000–$150,000 |
| Serious injury | $150,000–$500,000 |
| Severe / life-changing injury | $500,000+ |
Each case is assessed on its own facts. These figures are general ranges only. Cases involving permanent disability in a child, or a mother who has lost fertility or capacity to work, often exceed these ranges significantly.
Time limits apply in NSW. Generally, a person has three years from the date they knew — or ought to have known — that they suffered harm as a result of negligence. For children, different rules apply. Acting within those limits is important.
Bringing it together — do the pieces fit?
You may be reading this because something happened during your pregnancy or birth that still does not make sense. Perhaps you were told it was unavoidable. Perhaps nobody explained what went wrong. Perhaps you have a feeling that things should have gone differently.
These questions can help you think through what happened:
Understanding what happened is the first step. For a detailed explanation of how negligence claims work in NSW, see Reframe Legal — How Medical Negligence Claims Work in NSW.
You don’t need certainty to understand your position
Many people who experienced a placental complication feel uncertain about whether what happened was avoidable. That uncertainty is completely normal. Medicine is complex. Clinicians use language that is hard to understand. Hospitals sometimes provide little explanation after a traumatic event.
Legal clarity does not require you to be certain. It requires an examination of the facts — the clinical records, the timing of decisions, the imaging results, and what a competent clinician would have done in the same situation. A lawyer with expertise in medical negligence can assess those facts and give you an honest answer.
If consent was also an issue — for example, if nobody explained the risks of your delivery plan or the risks of a particular procedure — that is a separate but related legal question. For more on this, see Reframe Legal — Informed Consent and Medical Negligence.
If you want to understand your options for making a complaint about a clinician’s conduct, AHPRA — Australian Health Practitioner Regulation Agency handles complaints about registered health practitioners in Australia. A complaint to AHPRA is separate from a legal claim and does not affect your right to pursue compensation.
About the lawyer behind this article
Dr Rosemary Listing is a NSW lawyer with a PhD focused on medical negligence. Her academic and legal work examines how clinical failures cause harm — and how the law responds to those failures.
Placental complications sit at the intersection of obstetric urgency and clinical judgment. Dr Listing has worked on cases involving delayed caesarean decisions, undiagnosed placenta praevia, retained placenta, and placental abruption — conditions where the difference between timely action and delayed action can determine whether a baby survives, and in what condition.
Her experience reflects a consistent pattern: harm in these cases often comes not from the complication itself, but from the clinical team’s failure to recognise it, respond to it, or plan for it. The placenta is not an unpredictable organ — its risks are well understood, and the protocols for managing them are clear.
Families who seek legal advice after a placental complication are rarely looking to blame anyone. Most want to understand what happened and whether it could have been prevented. Dr Listing’s role is to examine the clinical record against the accepted standard of care and give an honest, evidence-based assessment.
Her approach is direct, thorough, and grounded in the medical and legal detail that these cases demand.
