Delayed Caesarean Sections and CTG Misinterpretation in Ireland

Parents whose child suffered a birth injury, including cerebral palsy, hypoxic-ischaemic encephalopathy (HIE), or permanent neurodevelopmental delay, may have grounds for a clinical negligence claim if delayed emergency caesarean section or CTG misinterpretation caused or contributed to that injury. Irish law sets a clear standard of care, and recent High Court decisions confirm that departures from that standard can found significant compensation awards.

The moment a birth goes wrong, everything changes. Parents who walked into a maternity ward filled with hope can find themselves, hours or days later, trying to make sense of what happened, and whether it needed to happen at all.

This guide is written for those parents. It sets out, plainly and honestly, what the clinical and legal standards for emergency caesarean care in Ireland actually require, what failure looks like in practice, and what steps you can take to find out whether your child’s injury was preventable. It draws on established Irish case law, clinical guidelines, and real settlement outcomes. It does not make promises. But it does tell you what to look for, and when it is worth asking the question.

The Reality in Irish Maternity Wards: What the Evidence Shows

Maternity care in Ireland has improved significantly over recent decades. But problems persist, and the State Claims Agency (SCA), which manages clinical negligence claims against public health bodies, publishes data that makes that clear.

Obstetric and maternity-related claims consistently represent one of the most significant categories of clinical negligence litigation in Ireland, both in volume and in the size of settlements reached. Brain injury at birth, caused by oxygen deprivation during labour, remains one of the most devastating and most frequently litigated outcomes. These injuries are not always unavoidable. Some occur because warning signs were missed, decisions were delayed, or escalation did not happen when it should have.

The systemic vulnerabilities are well documented: understaffed night shifts, over-reliance on verbal handovers, inconsistent CTG interpretation across teams, and delays between a decision to deliver by caesarean section and the actual delivery of the baby. In each of these failures, there is a window, sometimes as narrow as minutes, where intervention could have made the difference.

The Legal Standard of Care: The Dunne Principles

The legal framework for assessing clinical negligence in Ireland is anchored in three key cases.

Dunne v National Maternity Hospital [1989] IR 91 established what are known as the Dunne principles, the foundational test for clinical negligence that Irish courts have applied for over three decades. The core question is whether the medical practitioner was:

“Guilty of such failure as no medical practitioner of equal specialist or general status and skill would be guilty of if acting with ordinary care.”

This standard is set by reference to the medical profession’s own norms, not by what a judge or jury might consider reasonable in the abstract. It requires expert evidence to establish what an ordinarily competent practitioner would have done in the same circumstances.

Morrissey v HSE [2020] IESC 6 brought critical Supreme Court refinement to this framework, particularly in the context of cancer misdiagnosis but with principles that carry across clinical negligence more broadly. The Supreme Court confirmed that the Dunne standard must be applied with rigour, and that clinical guidelines, while relevant, do not themselves define the legal standard of care.

Perez v Coombe Women and Infants University Hospital and the HSE [2025] IEHC 396 is the most recent and, in many ways, the most instructive authority. In that case, the High Court was asked to consider the care provided to a patient who experienced a postpartum haemorrhage (PPH) at the Coombe Hospital. The judge reaffirmed that clinical guidelines, including IMEWS, RCOG, and NICE protocols, are guidance tools, not mandatory rules. Departing from a guideline does not automatically constitute negligence. Equally, following a guideline does not automatically discharge the duty of care.

What Perez makes clear is this: the courts will assess what a competent clinician, exercising genuine clinical judgment in the specific circumstances, would have done. That assessment requires independent expert evidence. It also means that minor departures from guidelines or imperfect documentation will not, on their own, establish negligence, but a pattern of failures that falls below the standard of an ordinarily competent practitioner can and does.

Clinical Standards: CTG Monitoring and Caesarean Timelines

What is CTG Monitoring and How Should it Be Interpreted?

A cardiotocograph (CTG) is the principal tool used to monitor fetal wellbeing during labour. It records the fetal heart rate and uterine contractions simultaneously, producing a continuous trace that clinicians interpret in real time.

The RCOG and NICE classify CTG features into four categories, normal, suspicious, pathological, and grow, each with specific escalation requirements. A suspicious trace requires a documented review and a management plan. A pathological trace requires immediate senior review and, depending on the clinical picture, may mandate urgent delivery.

Misinterpretation of a CTG trace is one of the most common failure patterns in birth injury claims. This includes:

  • Failure to recognise decelerations as pathological
  • Misclassification of an abnormal trace as reassuring
  • Failure to document CTG interpretation at appropriate intervals
  • Continuing Syntocinon (oxytocin) augmentation in the face of an abnormal or deteriorating trace

Decision-to-Delivery Intervals: What Does the Standard Require?

When a clinical decision is made to proceed to emergency caesarean section, the interval between that decision and the delivery of the baby is a critical measure of the adequacy of care. RCOG guidance classifies emergency caesarean sections by urgency:

  • Category 1 (immediate threat to maternal or fetal life): delivery should be achieved within 30 minutes of the decision
  • Category 2 (maternal or fetal compromise, not immediately life-threatening): delivery within 75 minutes

These timeframes are not aspirational targets. They represent the clinical standard that a competent obstetric unit is expected to meet. Delays beyond these intervals, particularly where fetal compromise was documented, are a central feature of many birth injury claims.

Common Failure Patterns: Did This Happen to You?

Most birth injury cases share recognisable patterns. Not all of them will be apparent from the clinical notes alone, but knowing what to look for is the first step.

Delayed recognition of fetal distress. The CTG showed deteriorating features, but the trace was not reviewed promptly, or the findings were not escalated to a senior clinician.

Failure to escalate. Junior staff identified a concern but did not call for senior review. Or a senior clinician was called but did not attend in a timely manner.

Inappropriate use of Syntocinon. Oxytocin was continued or increased despite a suspicious or pathological CTG trace, accelerating uterine contractions and reducing placental blood flow.

Delayed delivery. A decision to deliver by emergency caesarean section was made, but theatre was not prepared promptly, the anaesthetic team was not available, or other organisational failures extended the decision-to-delivery interval beyond acceptable limits.

Missing or altered documentation. The CTG trace is incomplete, the partogram shows unexplained gaps, or there are inconsistencies between contemporaneous records and retrospective entries in the clinical notes.

If any of these patterns are familiar to you, the next step is to understand whether there is a causal link between what happened and the injury your child sustained.

Proving Causation: Linking the Delay to the Injury

A clinical negligence claim requires more than proof of substandard care. It also requires proof that the substandard care caused or materially contributed to the injury. In birth injury cases, causation is established through a combination of clinical markers.

Metabolic acidosis at birth, reflected in cord blood gas values showing a low pH and elevated base deficit, is a key indicator of oxygen deprivation during labour. A base deficit greater than 12 mmol/L is associated with significant neonatal compromise.

Apgar scores at one, five, and ten minutes provide a contemporaneous snapshot of the newborn’s condition at delivery. Low scores, particularly at five and ten minutes, support the causation argument.

Brain MRI findings typically conducted in the days or weeks following birth, can identify the pattern and distribution of injury. The MRI pattern in HIE caused by acute near-total asphyxia differs from that caused by chronic partial hypoxia, and expert radiological evidence is used to establish the likely timing and mechanism of injury.

When causation is established, the question becomes: what would have happened if the care had been timely and competent? Expert evidence will typically address whether prompt intervention, earlier recognition of fetal distress, earlier delivery, would have prevented or reduced the degree of injury.

Compensation and Recent Irish Case Law

Irish courts award damages in birth injury cases under two broad headings.

General damages compensate for pain and suffering, past, present, and future. For a child with catastrophic and lifelong disability, these are significant, though capped by statute.

Special damages cover the financial losses associated with the injury: care costs, medical expenses, assistive technology, home adaptations, loss of future earnings, and the cost of therapeutic and educational support over a lifetime.

For children with severe or lifelong disabilities, courts will often approve interim settlements, a lump sum to meet immediate needs, with provision for a further hearing as the child’s prognosis becomes clearer. Periodic Payment Orders (PPOs) are also available, providing for annual payments rather than a single capital sum, which better reflects the ongoing nature of care costs.

Recent Irish settlements give an indication of the range of outcomes:

  • €17.6 million approved by the High Court in Helen and Arron v HSE, relating to a catastrophic birth injury sustained at an HSE hospital
  • €15 million the final settlement approved in Eoin Dunne v The Coombe Hospital, following a finding of liability against the hospital for injuries sustained at birth
  • €2.1 million (interim) approved in Patrick Brannigan v HSE, with provision for further proceedings, in a case involving a child born with dyskinetic cerebral palsy following birth at Cavan General Hospital

These figures reflect both the severity of the injuries involved and the lifetime cost of care. Each case turns on its own facts, and no two claims are alike. But they demonstrate that the Irish courts take birth injury claims seriously and that where negligence is established, the compensation awarded reflects the true cost to the child and the family.

Practical Guidance: What to Look For in Your Medical Records

You are entitled to request your child’s complete medical records and, where relevant, your own obstetric records. When those records arrive, the following three-document screen is a useful starting point.

The CTG Trace

The CTG trace is the continuous paper or electronic record of the fetal heart rate during labour. Look for gaps, handwritten annotations, and any notation indicating the trace was suspicious or pathological. Check whether there is a documented clinician review at each stage, and whether the response to any abnormality is recorded.

The Partogram and Midwifery Notes

The partogram is a graphical record of the progress of labour. Combined with the midwifery notes, it should show the timeline of cervical dilation, fetal position, uterine contractions, maternal observations, and any interventions. Look for gaps in the timeline, discrepancies between entries, and any record of escalation or the absence of escalation in response to concerns.

Theatre Logs

If your child was delivered by emergency caesarean section, the theatre log records the time the decision was made, the time theatre was prepared, the time the procedure commenced, and the time of delivery. The interval between decision and delivery is one of the most important numbers in a birth injury claim.

If records appear incomplete, inconsistent, or altered, raise this with your legal team immediately.

What Happens Next: Protecting Your Child’s Future

How Much Time Do You Have to Bring a Claim?

In Ireland, a clinical negligence claim must generally be brought within two years of the date of knowledge that is, the date on which you became aware, or ought reasonably to have become aware, that there was a connection between the care received and the injury sustained.

For children, the limitation period does not begin to run until the child’s eighteenth birthday, giving them until their twentieth birthday to bring a claim in their own right. However, a next friend, typically a parent, can bring proceedings on behalf of a minor at any time. Waiting is rarely in the child’s interests. Evidence deteriorates, witnesses become harder to locate, and the family’s ability to access therapeutic and educational supports in the interim may depend on resources that a successful claim can provide.

Why Early Investigation Matters

Early investigation allows your legal team to obtain and preserve the original CTG trace and clinical records before they are archived or destroyed. It allows a specialist independent expert to review the care at a time when their observations are most reliable. And it allows the family to make decisions, about care plans, about education, about the future, with a clearer picture of what happened and what remedies may be available.

Frequently Asked Questions

What is the Dunne Principles test for clinical negligence in Ireland?

The Dunne principles, established in Dunne v National Maternity Hospital [1989] IR 91, set out the legal test for breach of duty in Irish clinical negligence cases. The central question is whether a clinician was “guilty of such failure as no medical practitioner of equal specialist or general status and skill would be guilty of if acting with ordinary care.” The standard is set by reference to accepted medical practice, established through independent expert evidence.

Can I bring a birth injury claim if my child is still a minor?

Yes. A parent or guardian can bring proceedings as a “next friend” on behalf of a child at any time, regardless of the child’s age. The child’s own limitation period does not begin to run until their eighteenth birthday. However, early investigation is strongly advisable, both to preserve evidence and to access any interim supports that a successful claim can fund.

Does departing from a clinical guideline automatically prove negligence?

No. As confirmed in Perez v Coombe [2025] IEHC 396, clinical guidelines are guidance tools, not mandatory rules. A departure from a guideline does not automatically constitute negligence if the clinical decision made was otherwise reasonable in the circumstances. Conversely, following a guideline does not automatically discharge the duty of care. Negligence is assessed against the Dunne standard, established through expert evidence.

What types of compensation are available in birth injury cases?

Irish courts can award general damages (for pain and suffering) and special damages (for care costs, medical expenses, assistive technology, home adaptation, lost earnings, and educational and therapeutic support). For children with significant ongoing needs, courts can approve Periodic Payment Orders (PPOs), annual payments rather than a single lump sum, to better reflect lifetime care costs.

How do I know if the CTG trace was misinterpreted?

You will need an independent expert, typically a consultant obstetrician or midwife, to review the original trace and clinical records. Key indicators of misinterpretation include failure to classify an abnormal trace correctly, failure to escalate findings, and continuation of Syntocinon in the face of a deteriorating trace. Your legal team will commission this expert review as part of the initial investigation.

What if some of the medical records appear to be missing or altered?

Request the complete clinical records, including the original CTG trace, partogram, midwifery notes, and theatre logs. If records appear incomplete, inconsistent, or retrospectively amended, inform your solicitor immediately. Incomplete or altered documentation is a significant issue in birth injury litigation and may support an inference adverse to the hospital.
