Twin Delivery Complications & Birth Injury

A twin birth injury involving the second twin is a specific and well-documented clinical scenario. When a mother delivers twins, the interval between the delivery of the first and second baby, and the obstetric management of twin B during that interval, is a critical period governed by established clinical guidelines. If the second twin was injured during delivery, understanding the standard of care that applied, what went wrong, and who is responsible requires careful analysis of the operative and delivery records.

This article provides general legal information; consult a licensed Illinois attorney for advice specific to your situation.

The Second Twin’s Unique Risk Profile

Research consistently shows that the second-born twin faces higher perinatal risk than the first. The second twin is subject to: a potentially prolapsed umbilical cord after the first twin is delivered and the uterus partially decompresses; malpresentation (breech or transverse lie) that may require internal podalic version or breech extraction; placental abruption triggered by the change in uterine volume after the first delivery; and reduced uteroplacental circulation if delivery is delayed. Peer-reviewed literature, including studies by Leung et al. and Stein et al., has examined the relationship between inter-twin delivery interval and adverse outcomes for twin B, and ACOG Practice Bulletin 231 on multifetal gestations addresses delivery management for both twins.

Inter-Twin Delivery Interval: What ACOG Guidelines Require

ACOG Practice Bulletin 231 addresses the management of multifetal gestations, including the timing and mode of delivery for twin B. The Bulletin does not mandate a specific maximum number of minutes between deliveries as a bright-line rule, but it does require continuous electronic fetal monitoring of the second twin throughout the first twin’s delivery and the interval that follows, and it directs that the delivery team be prepared to promptly deliver twin B if fetal heart rate abnormalities develop.

The question in a birth injury case is not whether a specific number of minutes elapsed, it is whether the clinical team was continuously monitoring twin B’s fetal heart rate, responded appropriately to any decelerations or bradycardia detected during the inter-twin interval, and had the skill and equipment available to perform an expedited delivery when indicated. A prolonged interval alone is not necessarily negligent; a prolonged interval during which the team failed to monitor or failed to act on detected fetal distress is a different matter.

Mode of Delivery for Twin B: Breech Extraction and Internal Version

When twin B is in a non-vertex (non-head-first) presentation, the delivering obstetrician may need to perform an internal podalic version, manually rotating the baby within the uterus, followed by breech extraction, in which the physician delivers the baby feet-first. These are skilled maneuvers that require specific training and should be performed under continuous ultrasound guidance. ACOG Practice Bulletin 231 addresses the evidence base for these techniques in multifetal deliveries.

Errors in the execution of internal version or breech extraction, including excessive traction, failure to use ultrasound guidance, or performing the maneuver without adequate preparation, can cause direct physical injury to twin B, including brachial plexus injury, cervical spine injury, or traumatic hypoxia. These are distinct injury mechanisms from the oxygen-deprivation injuries that can also occur during this period, and the clinical records typically document which occurred.

Continuous Monitoring Obligations During Twin Labor

A critical standard-of-care issue in twin delivery cases is whether both twins were continuously monitored throughout the labor and delivery process. External fetal monitoring equipment must be positioned to capture heart rate tracings for each twin separately. After the first twin is delivered, internal monitoring of twin B may be indicated to maintain continuous tracing until delivery. Gaps in the monitoring record, periods during which twin B’s fetal heart rate was not documented, are clinically significant findings that a birth injury attorney and reviewing expert will examine carefully.

When monitoring gaps coincide with the development of neonatal neurological injury in twin B, the evidentiary link between the monitoring failure and the outcome becomes a central issue in the case. If the injury resulted in oxygen deprivation affecting the brain, our attorneys who handle HIE and infant brain damage from birth can evaluate that aspect of the claim as part of a comprehensive review of the twin delivery.

A Hypothetical: The Delayed Twin B Delivery

The following is a hypothetical scenario, not a description of any actual case, provided to illustrate how these issues typically arise. Twin A delivers vaginally without complication. Twin B is in a transverse lie, and the monitor begins showing a prolonged deceleration two minutes after Twin A’s delivery. Nursing documentation shows the deceleration was charted, but the attending physician, who had left the room to attend to Twin A, was not immediately notified. By the time an internal version and breech extraction is attempted, twenty-eight minutes have passed since the deceleration began. Twin B is delivered with a low Apgar score and is later diagnosed with hypoxic-ischemic encephalopathy. In a case like this, the medical record itself, the timing of the deceleration, the timing of physician notification, and the timing of delivery, becomes the central evidence a reviewing expert examines.

How a Twin Birth Injury Case Is Evaluated Under Illinois Law

A birth injury malpractice claim arising from a twin delivery is a healing-art claim subject to Illinois requirements, including the 2-622 affidavit requirement under 735 ILCS 5/2-622. Before a complaint may be filed, an attorney must obtain a written certification from a qualified reviewing health professional confirming that the claim has reasonable and meritorious cause. In a twin delivery case, the reviewing expert will typically be a maternal-fetal medicine specialist or obstetrician with experience in multifetal gestations.

The review must assess: whether the delivery team complied with ACOG Practice Bulletin 231 guidance on twin delivery management; whether continuous monitoring was maintained for twin B; whether the inter-twin interval was managed appropriately given the clinical picture; whether the mode of delivery for twin B was indicated and executed correctly; and whether the hospital was appropriately staffed for a twin delivery, including the availability of neonatal resuscitation personnel for each baby at the time of delivery.

Illinois Filing Deadlines and Damages

A twin birth injury claim is subject to the same Illinois deadlines that apply to any birth injury case. Under 735 ILCS 5/13-212, a child’s own claim generally must be filed within eight years of the negligent act and never after the child’s 22nd birthday, and because a delivery-room injury has a fixed date, the eight-year prong is almost always the one that controls. A mother pursuing her own claim, for example over a delayed or complicated delivery of Twin B that also harmed her, generally has two years from discovering the injury, with a four-year outer limit, a separate and typically shorter deadline from her child’s. If either twin was delivered at a public or county hospital, a different, shorter notice period applies under 745 ILCS 10/8-102 of the Local Governmental and Governmental Employees Tort Immunity Act, so confirming the facility type early matters.

Illinois places no cap on non-economic damages in medical malpractice cases. The Illinois Supreme Court struck down the state’s previous statutory damages cap in Lebron v. Gottlieb Memorial Hospital, 237 Ill. 2d 217 (2010). What a twin birth injury claim is worth depends on the documented severity of the injury, the lifetime care the child will need, and the strength of the causation evidence connecting the delivery-management decisions to the outcome. Illinois law also does not generally allow punitive damages in medical malpractice actions; compensation is intended to address the actual harm and the costs it creates, not to punish the provider.

Common Defenses Hospitals and Physicians Raise

Twin delivery cases are defended aggressively, and a few arguments come up repeatedly. The defense may argue that the injury to Twin B resulted from an unavoidable complication of twin gestation itself, twins are, on average, at higher risk regardless of how the delivery is managed, rather than from any delay or error. The defense may also argue that the inter-twin interval, even if longer than average, fell within an acceptable range given the clinical picture at the time, since ACOG guidance does not set a fixed maximum number of minutes. In cases involving a breech extraction or internal version, the defense will often argue the maneuver was performed correctly and that any injury reflects an inherent risk of the procedure rather than a deviation from accepted technique. A thorough record review by a maternal-fetal medicine expert is what separates an inherent-risk outcome from a preventable one.

Hospitals will also sometimes point to the mother’s own prenatal course, arguing that a factor such as polyhydramnios, an unusual fetal position discovered late in pregnancy, or a short interval between pregnancies contributed to the outcome independent of anything done during delivery. These arguments do not automatically defeat a claim; they simply narrow the dispute to whether the delivery team’s response to the known risk factors, once labor began, met the applicable standard. An attorney reviewing a twin delivery case will want to know what was documented in the prenatal chart about the twins’ presentations and estimated weights well before delivery, since that context often shapes how the defense frames its explanation for what happened.

What Compensation Can Cover

When a twin birth injury claim succeeds, compensation can address the medical and life expenses tied to the injury, including past and future medical care, rehabilitative and developmental therapies, any special education or in-home support the child will need, and the impact of the injury on the family’s daily life. If the mother was also harmed, for example by a complicated or delayed delivery of the second twin, her own claim is evaluated and valued separately from her child’s. An attorney can walk through which categories of loss apply to your specific situation once the medical records have been reviewed.

How These Cases Are Investigated

A twin delivery investigation typically begins with obtaining the complete labor and delivery record for both babies, not just the summary discharge paperwork. That includes the continuous fetal heart rate strips for Twin A and Twin B, nursing flow sheets, the operative note if any instrumented delivery or version was performed, anesthesia records if a cesarean was performed for either twin, and the neonatal resuscitation record for each baby. Because two deliveries are documented on overlapping timelines, reconstructing exactly what was happening to Twin B while the team was focused on Twin A is often the single most important piece of investigative work. An experienced birth injury attorney will typically have a maternal-fetal medicine expert build a minute-by-minute timeline from the fetal monitor strips before forming any opinion on whether the standard of care was met.

Chicago and Cook County Considerations

Twin deliveries are frequently managed at Chicago-area hospitals with dedicated maternal-fetal medicine and high-risk obstetrics programs, precisely because twin pregnancies carry elevated risk. That can work in a family’s favor evidentially, these facilities typically have more detailed monitoring records and more complete documentation of staffing and decision-making during the delivery, but it also means the delivery may have involved multiple physicians, residents, and nursing staff, each of whose role needs to be untangled. If your twins were delivered at different points by a rotating labor and delivery team, or if a resident or on-call physician was involved in addition to your primary OB, identifying every potentially responsible party is part of a thorough case review.

Frequently Asked Questions

Does it matter that Twin A was delivered without any problems?
No. Twin A’s uncomplicated delivery does not diminish a claim involving Twin B. The two deliveries are medically and legally distinct events, and the standard of care owed to Twin B is evaluated on its own facts.

Is there a legal limit on how long the delivery of the second twin can take?
No fixed number of minutes is written into the standard of care. What matters is whether the clinical team continuously monitored Twin B and responded appropriately to what the monitor showed, not whether a specific clock ran out.

Can both the doctor and the hospital be responsible?
Yes. The physician can be responsible for delivery-management decisions, while the hospital can be separately responsible for its nursing staff’s monitoring and communication, and for whether the facility was adequately staffed for a twin delivery.

What if my child was diagnosed with a developmental delay months after the twin delivery, not right away?
A delayed diagnosis does not close the door on a claim. The clock under 735 ILCS 5/13-212 runs from the negligent act, not from the diagnosis, and a delivery-room injury has a fixed date regardless of when the resulting condition is later identified.

Do I need a specific type of medical expert for a twin delivery case?
Typically yes. Twin delivery cases usually require a maternal-fetal medicine specialist or an obstetrician experienced in multifetal deliveries to speak to the ACOG guidelines and standard practices specific to twin gestations, in addition to any neonatology or pediatric neurology experts needed to address the injury itself.

What if the delivery records for Twin A and Twin B were combined into a single chart and it is unclear which entries apply to which baby?
This happens more often than families expect, and it is exactly the kind of documentation problem an experienced birth injury attorney and reviewing expert know how to untangle by cross-referencing timestamps, the separate monitor strips, and the delivery summary to determine which entries correspond to each twin.
