Intrapartum Stillbirth Risk in Complicated Pregnancies What Indian Study Reveals About Fetal Survival

A fetus who is alive when labour begins can still be lost before birth if complications are not recognised and acted on quickly. That is the clinical weight of intrapartum stillbirth. It often reflects a narrow window where diagnosis, referral, monitoring, and delivery decisions must work together.

A multicentre prospective cohort study from India helps sharpen this issue. By following pregnant women with complications across multiple facilities, the study moved beyond broad stillbirth counts and looked at a more urgent question: which fetuses survive labour when the pregnancy is already complicated, and which conditions sharply reduce that chance?

The findings matter for obstetricians, midwives, anaesthetists, referral teams, and public health planners. They show that intrapartum stillbirth is rarely the result of one isolated event. It is usually the endpoint of overlapping risks, including maternal illness, fetal compromise, delayed care, and health-system barriers.

Complicated labour needs timely assessment and close fetal monitoring.

Why intrapartum stillbirth deserves separate attention

Stillbirths are often grouped together, but timing changes the meaning. An antepartum stillbirth occurs before labour. An intrapartum stillbirth occurs during labour or delivery, after the fetus was alive at the onset of labour or admission.

That distinction is crucial. Intrapartum deaths are more closely linked with:

• Delayed recognition of fetal distress

• Obstructed or prolonged labour

• Placental abruption or severe bleeding

• Hypertensive emergencies

• Uterine rupture

• Infection and sepsis

• Late referral from smaller facilities

• Limited access to emergency caesarean section, blood, anaesthesia, or neonatal support

  
  

Globally, around 1.9 million stillbirths occur each year, with the highest burden in low- and middle-income countries. India has made progress in reducing stillbirth rates, but because of its population size, it still contributes a large absolute number of fetal deaths. Intrapartum stillbirth is especially important because many cases may be preventable with timely, high-quality intrapartum care.

The Indian prospective cohort adds depth because it focused on women who were already at higher risk. These were not routine pregnancies. They included complications such as hypertensive disorders, haemorrhage, anaemia, malpresentation, preterm labour, medical illness, or suspected fetal compromise.

That makes the study clinically useful. It reflects the reality of referral hospitals and district-level maternity units, where providers often manage several risks at once.

What the India cohort showed about fetal survival

The major strength of a prospective cohort design is that it follows patients forward in time. Instead of asking after the event what might have happened, the study records maternal condition, fetal status, complications, care pathways, and outcomes as they unfold.

In this Indian multicentre cohort, fetal survival was not evenly distributed across all complicated pregnancies. Survival probabilities were highest when complications were identified early, the fetal heart rate was reassuring, labour was monitored, and delivery occurred before maternal or fetal deterioration.

Survival probabilities were lower when pregnancies involved severe or combined complications, especially when fetal compromise was already present at admission.

The central message is clear: among pregnant women with complications, fetal survival during labour depends heavily on how early risk is identified and how quickly effective care begins.

The study’s survival analysis is useful because it frames intrapartum stillbirth as a time-sensitive outcome. A fetus may be alive at admission, but the probability of survival can fall as labour continues in the presence of hypoxia, bleeding, infection, severe hypertension, or mechanical obstruction.

In practical terms, survival probability answers a simple but urgent question: given this complication profile, what is the chance that the fetus remains alive until birth?

That question changes clinical behaviour. It supports earlier escalation, more frequent fetal assessment, and a lower threshold for intervention when several warning signs are present.

Fetal heart rate at admission is one of the most important early signals.

The main risk factors for intrapartum stillbirth in complicated pregnancies

The RISK FACTORS FOR INTRAPARTUM STILLBIRTH identified in the Indian cohort fit closely with what obstetric practice already recognises, but the study helps show how these factors cluster in high-risk women.

Abnormal fetal heart rate at admission

A non-reassuring fetal heart rate is one of the clearest warning signs. If the fetus is already bradycardic, tachycardic, or showing signs of distress at first assessment, the margin for delay becomes very small.

In the cohort, fetal compromise at admission was strongly linked with poorer survival. This is expected biologically. An abnormal fetal heart rate may reflect hypoxia from placental insufficiency, cord compression, abruption, uterine hyperstimulation, sepsis, or prolonged obstructed labour.

A normal fetal heart rate does not remove risk, but an abnormal rate should trigger urgent senior review and a clear delivery plan.

Antepartum haemorrhage and placental abruption

Bleeding in late pregnancy is a major threat to both mother and fetus. Placental abruption is particularly dangerous because it can rapidly reduce oxygen transfer and cause maternal shock or coagulopathy.

In the Indian cohort, haemorrhagic complications were among the conditions associated with lower fetal survival during labour. This is clinically consistent. Once placental separation begins, fetal reserve can fall quickly.

Care teams need rapid assessment of maternal haemodynamics, fetal status, blood availability, and the feasibility of immediate delivery.

Hypertensive disorders of pregnancy

Severe pre-eclampsia and eclampsia can affect fetal survival through placental insufficiency, fetal growth restriction, abruption, prematurity, and emergency delivery under unstable conditions.

The cohort’s findings reinforce the need to treat hypertension as both a maternal and fetal emergency. Blood pressure control, magnesium sulphate for seizure prevention or treatment, timely delivery planning, and fetal monitoring all matter.

India’s maternal health programmes have rightly focused on detecting hypertensive disorders earlier through antenatal care. The intrapartum period must continue that vigilance.

Preterm birth and low birth weight

Preterm fetuses and growth-restricted fetuses have less physiological reserve. They tolerate hypoxia, infection, and labour stress poorly compared with term fetuses of appropriate weight.

The Indian study found that fetal survival probabilities were lower in these vulnerable groups, especially when prematurity or low birth weight occurred alongside maternal complications.

For providers, this means that gestational age and estimated fetal weight should shape the urgency of monitoring and delivery decisions. A compromised preterm fetus may deteriorate faster, even when labour appears to be progressing.

Obstructed labour, malpresentation, and uterine rupture

Mechanical complications remain major contributors to intrapartum fetal death. Obstructed labour can cause prolonged fetal hypoxia. Malpresentation may delay delivery or increase the need for operative intervention. Uterine rupture is a catastrophic event for both mother and fetus.

These risks are closely tied to the referral pathway. A woman may arrive after many hours of labour, after failed induction, or after attempts at delivery where emergency surgery was not available.

The cohort highlights a familiar but painful pattern: fetal survival falls when definitive care begins late.

Infection and maternal systemic illness

Maternal fever, chorioamnionitis, sepsis, severe anaemia, cardiac disease, and other systemic illnesses can all reduce fetal oxygen delivery. Severe anaemia is particularly relevant in India, where anaemia in pregnancy remains common despite national supplementation programmes.

When infection or systemic illness is present, fetal monitoring should not be treated as optional. Maternal stabilisation and fetal assessment must proceed together.

How survival probabilities should guide care

Survival probability is not a crystal ball. It does not predict the outcome for one fetus with certainty. It gives a risk estimate based on patterns seen across many pregnancies.

That still has practical value. In the Indian cohort, survival curves helped show that fetal loss during labour was more likely when high-risk features appeared early, clustered together, or persisted without timely intervention.

A helpful way to interpret survival probability is to think in three clinical zones.

Clinical zone	Typical features	What providers should do
Higher survival probability	Single complication, stable mother, reassuring fetal heart rate, early presentation	Continue close monitoring, treat the maternal condition, prepare for escalation if signs change
Intermediate survival probability	More than one complication, uncertain fetal status, preterm labour, referral from another facility	Increase monitoring frequency, involve senior staff early, confirm blood and theatre readiness
Lower survival probability	Abnormal fetal heart rate, severe bleeding, eclampsia, obstructed labour, uterine rupture, shock, severe infection	Treat as an obstetric emergency, stabilise the mother, expedite delivery when appropriate

The key point is not that every high-risk pregnancy needs immediate caesarean section. The point is that delay must have a reason. If the fetus is compromised and the mother has a severe complication, waiting without a clear plan can be dangerous.

Referral delays can reduce fetal survival before hospital care begins.

Implications for maternal health in India

The study’s findings are not only about fetal outcomes. They also reflect the broader maternal health system.

A pregnancy that ends in intrapartum stillbirth often involves serious maternal risk. Severe bleeding, eclampsia, sepsis, obstructed labour, and uterine rupture can also lead to maternal near-miss events or maternal death.

This creates a dual obligation. Improving fetal survival in complicated pregnancies also means improving maternal survival.

Several health-system issues become clear.

Referral quality matters. A referral is not complete when a patient leaves one facility. It is complete when the receiving facility is ready, informed, and able to act.

Antenatal risk detection is not enough. Many complications worsen during labour. Labour rooms need reliable monitoring, documentation, and escalation pathways.

Emergency obstetric care must be functional at all hours. Caesarean capability, blood products, anaesthesia, magnesium sulphate, antihypertensives, antibiotics, and neonatal resuscitation cannot be available only in theory.

Stillbirth review should be routine. Each intrapartum stillbirth should be reviewed without blame, with attention to timing, decision points, referral delays, fetal monitoring, and resource gaps.

For India, these findings align with national priorities around respectful maternity care, reduction of preventable maternal and perinatal deaths, and strengthening of facility-based childbirth services.

Recommendations for healthcare providers

The findings point to practical steps that can improve fetal survival in complicated pregnancies.

Assess fetal status immediately at admission

Every woman in labour with a complication should have prompt fetal heart rate assessment. If the fetal heart rate is abnormal, repeat confirmation should not delay action.

Admission triage should include:

• Maternal vital signs

• Obstetric history and gestational age

• Stage of labour

• Fetal heart rate

• Bleeding, fever, convulsions, pain, or rupture of membranes

• Prior caesarean section or uterine surgery

• Referral details and treatment already given

  
  

Use risk clustering rather than single labels

A diagnosis such as “pre-eclampsia” is not enough. Providers should ask what else is present.

For example, severe pre-eclampsia with normal fetal heart rate and early gestation is different from severe pre-eclampsia with abruption, fetal bradycardia, and maternal shock.

Risk rises when complications stack together.

Shorten decision-to-delivery intervals for emergencies

When fetal distress occurs with severe maternal complications, teams should avoid slow escalation. Senior decision-makers, anaesthesia, theatre staff, blood bank, and neonatal teams should be alerted early.

The goal is not rushed care. The goal is coordinated care without avoidable waiting.

Strengthen referral communication

Referring facilities should communicate:

• Reason for referral

• Fetal heart rate before transfer

• Maternal blood pressure, pulse, temperature, and bleeding status

• Labour duration and cervical findings

• Medicines given

• Estimated time of arrival

  
  

Receiving facilities should prepare before the patient reaches the labour room, especially when the referral involves haemorrhage, eclampsia, obstructed labour, or suspected fetal distress.

Conduct perinatal death audits

Audit should focus on learning. Useful questions include:

• Was the fetus alive at admission?

• Was fetal heart rate documented correctly and repeatedly?

• Were warning signs acted on?

• Was referral timely?

• Was theatre, blood, or anaesthesia delayed?

• Could antenatal care have detected the risk earlier?

• Was the family treated respectfully?

  
  

Over time, these reviews can reveal patterns that one case alone may not show.

Clear documentation helps teams recognise deterioration earlier.

What the study means for clinical practice

The India multicentre cohort reinforces a practical lesson: complicated pregnancies need dynamic risk assessment. A woman’s risk status can change within minutes during labour, and fetal survival can change with it.

For obstetric and maternal-fetal medicine teams, the study supports three priorities.

Early recognition

Identify maternal and fetal danger signs before they become irreversible.

Timely escalation

Bring in senior staff and emergency resources as soon as high-risk features appear.

System readiness

Make sure life-saving care is available when labour complications occur, not after a delay.

Intrapartum stillbirth is a devastating outcome, but the study shows that it is also a measurable and often preventable one. Survival probabilities give clinicians a clearer way to think about time, risk, and urgency. In complicated pregnancies, that clarity can make the difference between fetal survival and loss.
