Babies on a Plane: Air Travel, Pregnancy, and In-Flight Emergencies

Depending on your perspective, the idea of delivering a baby on a plane might be exciting… or your worst nightmare! Today we’ll talk about what to think about in this scenario, and familiarize you with what you have available for this in-flight emergency.

First of all… what recommendations are there for air travel (i.e., can we prevent this??)

  • There is an ACOG Committee Opinion on Air Travel During Pregnancy (reaffirmed 2019)

  • Highlights:

    • Air travel is safe for pregnant folks, and there’s no increased risk of adverse events following occasional air travel.

    • Most airlines will allow for air travel up until 36 weeks.

      • The Points Guy blog had a recent post comparing airline policies, if you’re interested! 

      • If travel is necessary after 36 weeks, most airlines will require a doctor’s note clearing the patient to fly.

    • Remind patients traveling to reduce VTE risk with compression stockings, frequent movement/ambulation (at least 1x/hr), and adequate hydration.

    • Risk of radiation for occasional air travelers is fairly minimal.

How common is the scenario of a birth on a plane?

  • It’s not very common – but also hard to find estimates.

So if I’m on a 1 in 26 million flight… 

  • First – we’ll plug a paid app called AirRx that’s written for physicians to know about what in-flight emergencies are common, and what you can expect to have access to in a flight.

    • Information is destination/origin specific, so also useful for international air travel.

    • We’ll focus on US-origin (mostly domestic) flights.

  • Every flight has first aid kits:

    • If under 50 passenger seats, minimum 1 kit.

    • If 51-150, minimum 2.

    • If 151-250, minimum 3 - this is a Boeing 737 size.

    • If 251+, minimum 4. 

      • First aid kits on planes have some basic equipment, including antiseptic swabs, bandages, adhesive tape, and bandage scissors.  

  • Separately, all commercial aircraft in the USA are required to carry a separate “emergency medical kit” that contains more advanced equipment:

    • Stethoscope and BP cuff

    • Airway supplies

    • PPE for you (gloves, gown, etc).

    • IV tubing set with at least 500cc bag of NS 

    • Tylenol, benadryl, aspirin

    • Epinephrine, nitroglycerin, and atropine

    • Automatic external defibrillator

    • And some basic instructions for use of drugs in the kit.

  • You will also have access to oxygen and masks.

Who can help?

  • It’s good to keep in mind you have a team, and you’re never alone if you’re helping the crew respond to an in-flight emergency.

    • Always share with flight crew yourself, your level of training, and show a medical ID if you have it.

    • If someone has already volunteered, don’t be shy about volunteering, too – you never know who might have good skills to assist (especially if you’re an OB on a plane where a baby might be coming!).

    • Also if you’re the only one who has responded – feel free to ask the crew to keep asking for additional assists if you need more folks to help.

  • On board, you’ll have a flight crew:

    • Ask them to bring the emergency medical kit and first aid kit.

    • Ask one flight attendant to be an assist throughout the event (usually one will be assigned).

    • The crew will notify a ground medical support team, who is well-trained in a wide variety of scenarios as well as specific physiology of flight.

  • Talking to your ground medical crew:

    • Be explicit about your impression of what’s going on.

    • Keep what you say simple.

    • Keep talking and keep everyone informed – your pilot and crew are often trying to help with weighing a decision about whether emergency landing is warranted.

      • This is more than the medical decision – part of this is airport choice, whether the plane is safe to land (i.e., is the extra fuel of landing early making the plane too heavy for a safe landing), and whether resources are available to assist the patient where landing is considered.

      • Especially if there is concern for communicable disease, flight crew needs to be aware for themselves and to alert ground medical crew for transport considerations.

    • Be professional – all conversations with medical ground crew are recorded!

Starting your assessment

  • Get basic vitals - vital signs are vital!

  • Get your history.

  • Do what you do best as an OB – assess labor or not in labor!

    • You are limited in the air - you have your physical exam, and that’s about it.

    • Your goal is to promote safety of the patient and passengers with your professional assessment. 

    • You’ll have assistance from ground medical staff on what to do in specific scenarios regarding flight diversion.

  • Pregnant folks also have a lot of other things that can be occurring – keep your differential diagnosis broad and reassure folks if labor is not occurring. You may be the best person to limit panic in assessing a pregnant person on board a plane, regardless of the complaint.

  • If delivery is occurring, get help!

    • You know you need assistants, even if not trained.

    • Be prescriptive and talk out loud – think about how you simulate a shoulder dystocia. Now imagine that on a plane with no nurses, no backup, no anesthesia – you have to be directive in making sure you get what you need to succeed.

What about weird / crazy / undesirable scenarios in the air?

  • Preterm labor:

    • Remember these babies need breathing and warmth primarily!

      • In your emergency medical kit, you have equipment for PPV and oxygen that can be administered to babies.

      • Skin-to-skin, layers, and blankets are readily available on planes for warmth.

      • For super premature kids, we often will put them in plastic bags to help with heat retention… and on planes, there’s often several of those! Ask for a gallon Ziploc bag from volunteering passengers.

  • Malpresentation (i.e., breech or cord prolapse).

    • Don’t encourage pushing in these scenarios! Be clear with ground crew an emergent cesarean is needed and landing the plane needs to be a top consideration. 

    • Get patient into all fours for a cord prolapse, with chest down and butt up – this will help presenting parts stay off the cord.

    • If the baby is coming – go through our breech delivery episode and simulate breech deliveries while you can in training! 

  • Postpartum hemorrhage

    • You’re limited in what you can do here – bimanual massage, examination, pressure, and bandages. 

    • You have a limited amount of IV crystalloid on a plane you can give. 

    • Remember that nipple stimulation can help with oxytocin production – starting breastfeeding or doing nipple stim can get the uterus contracting.

    • Consider delaying placental delivery until the plane is landed – remember you have 30 minutes in an active management scenario. If there’s no active bleeding and baby is delivered, without oxytocin, it may be prudent to wait to not provoke bleeding.

What about medicolegal implications?

  • There is no relevant international law for assisting in-flight medical emergencies.

  • In the US, the Aviational Medical Assistance Act (aka, “Good Samaritan Act”) of 1998 states:

    • An individual shall not be held liable for damages in any action brought in a Federal or State court arising out of the acts or omissions of the individual in providing or attempting to provide assistance in the case of an in-flight medical emergency, unless the individual, while rendering such assistance, is guilty of gross negligence or willful misconduct.

      • The standard for malpractice here is significantly higher than it is in usual malpractice cases.

      • There is no example of a medical professional anywhere in the world who has been sued successfully for assisting an ill traveler

        • Actually - successful lawsuits have only occurred against airlines; and airlines will normally accept liability associated with requests for in-flight assistance. 

  • There likewise is no standard protocol for documentation of in-flight events and assistance; but individual airlines may have forms or policies.

    • It is advisable for you to create a secure document of your exam, assessment, and plan, or get a photo of a completed airline documentation form, for your own records in case you are asked to comment on the case later for any reason.

What about compensation?

  • The Good Samaritan law only applies to true “good samaritan” actions, so where no compensation is provided. Because of this, it’s not advisable to take any monetary compensation for assisting in an in-flight emergency.

    • These laws do not address non-monetary compensation (i.e., frequent flyer miles, seat upgrade, bottle of wine, etc.). 

      • However, just because they are not addressed doesn’t mean they may not be targeted, so most folks advise not accepting these gifts.

    • Lawsuits have been brought against assisting physicians; just none of them have succeeded in US courts to date.

Final Fun Facts

  • If a baby is born in flight, most of the time the child is given citizenship status of the parents.

    • If in US airspace, the child can also be given US birthright citizenship.

    • Sometimes, citizenship is awarded based on the country of registration of the plane.

  • The most recent baby we could find born on a plane occurred in Oct. 2022:


The Twin Birth Study

Here’s the RoshReview Question of the Week:

Which of the following needs to be met to undergo vaginal delivery with a monochorionic-diamniotic twin pregnancy with vertex twin A?

Check your answer and get a special RoshReview deal for listeners at the links above!


Actual title: A Randomized Trial of Planned Cesarean or Vaginal Delivery for Twin Pregnancy

https://www.nejm.org/doi/full/10.1056/nejmoa1214939 

Background:

  • Where was the study published?

    • NEJM, October 3, 2013

  • Why was the study done?

    • Tthrough the 1990s and 2000s there was a significant rise in twin births in the USA, likely attributed to advancing maternal age (when twinning is more common spontaneously) and the use of reproductive technology – ovulation induction and IVF.

    • In the wake of the Term Breech trial, as well as some observational studies looking at twins specifically, there was concern that breech birth risks could be extended to twins – and practice was changing!

      • In 1995, 53.9% of twin births were by CS. By 2008, this number was 75%. 

    • Not all observational studies were in agreement about the risk of “breech extraction” of a second twin, specifically – so a new study was planned and performed.

  • Who performed the study?

    • The “Twin Birth Study Collaborative Group” – a large multinational collaborative, but with the main site at the University of Toronto and funded by the Canadian Institutes of Health Research – the same funders that brought you the Term Breech Trial!

      • You’ll note a lot of similarities (but also some important differences!) between this study and the Term Breech Trial. We definitely recommend a compare-contrast session!

  • What was the research objective?

    • To compare the risk of fetal/neonatal death or serious morbidity between planned cesarean or planned vaginal delivery for twin pregnancies between 32w0d and 38w6d, if the presenting twin was in cephalic presentation. 

Methods:

  • Who participated and when?

    • Recruitment between December 13, 2003 and April 4, 2011 at 106 centers in 25 countries.

    • Enrolled 1392 patients in the planned cesarean group and 1392 patients in the planned vaginal delivery group.

  • Eligibility:

    • Needed to have:

      • Twin pregnancy between 32w and 38w6d

      • First twin in cephalic presentation

      • Both fetuses alive with EFW between 1500g and 4000g, confirmed by ultrasound within 7 days before randomization

    • Exclusions:

      • Monoamniotic twins

      • Lethal fetal anomalies

      • Other contraindication to labor or vaginal delivery (including 2nd twin being “substantially larger” than the first)

      • Prior cesarean with vertical incision or more than one LTCS

  • Management:

    • Delivery by cesarean or by labor induction was planned between 37w5d and 38w6d

    • If in the CD group, if the first twin delivered vaginally, then a c-section was attempted for the second twin if logistically possible.

    • In the VD group:

      • Continuous EFM was “recommended” during active labor

      • Use of oxytocin and epidural analgesia were left to OB provider discretion

      • After delivery of first twin, use of US was “encouraged” to check second twin presentation

        • If cephalic, amniotomy was delayed until head was engaged and SVD anticipated, unless for other OB indication

        • If non-cephalic, OB decided on best delivery option – spontaneous or assisted breech delivery, total breech extraction +/- internal podalic version, ECV and vaginal cephalic delivery, or intrapartum CD

      • Deliveries were attended by qualified OB experienced in twin delivery, defined as a OB who judged themselves to be experienced at twin delivery and whose department head agreed with this judgment (similarly to Term Breech Trial).

  • Outcomes:

    • Primary: fetal/neonatal mortality or serious neonatal morbidity, assessed up to 28 days after birth.

      • Morbidities included many of the same things in the Term Breech Trial, and were serious neonatal morbidities (for the sake of brevity, we won’t list them out).

    • Secondary: maternal death or serious maternal morbidity, assessed up to 28 days after delivery.

      • Again, this was very similar to the Term Breech Trial. 

    • A number of subgroup analyses were planned for the primary outcome, including by nulliparity; gestational age at randomization; maternal age; presentation of the second twin; chorionicity; and the perinatal mortality rate in the mother’s country of residence. 

Results

  • Who was recruited?

    • Outcome data was available for 1392 women (2783 fetuses/infants) in the cesarean group and 1392 women (2782 fetuses/infants) in the vaginal delivery group. 

    • Baseline characteristics were overall similar, and most patients (82.4%) underwent randomization between 32w0d and 36w6d. 

      • More than half of the infants in each group were born at 37w0d or later. 

        • Around 5-6% in each group were between 32w and 33w6d, and another 42% between 34w0d to 36w6d. 

      • The time from randomization to delivery was similar but slightly different between groups (12.4 vs 13.3 days).

  • In the planned CD group: 

    • 90% had CD

    • 1% had a combined vaginal-cesarean delivery, and 

    • 9% had both twins vaginally.

      • Almost 60% of the CDs were performed before the onset of labor.

  • In the planned VD group:

    • 56% delivered both twins vaginally, 

    • 4% had a combined vaginal-cesarean delivery, and 

    • 40% had a cesarean for both twins.

      • Of those in the VD group who had a CD, 67.5% of them were performed during labor (or another way to look at it, 32.5% had a CD prior to labor in the planned VD group).

    • 95% had an experienced OB present, according to the study definition

  • Primary Outcome:

    • The frequency of composite primary outcome did not differ between planned CD (60, or 2.2%) and planned VD (52, or 1.9%) groups.

      • The only variable that appeared to modify the risk of the primary outcome was earlier gestational age at randomization. 

      • The number of deaths in each group was 24 (0.9%) in CD group and 17 (0.6%) in VD group. 

        • 11 of these deaths in the CD group and 8 in the VD group were before labor onset.

    • In subgroup analyses, there was no significant interaction with the primary outcome with respect to parity, gestational age at randomization, presentation of the second twin, chorionicity, or national perinatal mortality rate. 

    • The second twin was more likely than the first to have the primary outcome, but this was not different between the groups. 

  • Secondary outcome:

    • There were no differences in primary maternal composite outcome rates (7.3% CD, 8.5% VD). 

Impact

  • What is the impact of all of this, and what are we doing now?

    • This paper certainly helped to encourage the training and planning of vaginal delivery of the second twin, including by breech delivery by stating that no increased risk was seen with a policy of planned vaginal delivery. 

      • In ACOG PB 231 on multifetal gestation, it notes that vaginal delivery of a non-cephalic second twin is reasonable, provided an OB with experience is present.

      • That’s key – it’s apparent in this paper that, compared with the Term Breech Trial, there was more emphasis on patient counseling / selection (i.e., 13 day median from randomization to delivery, protocolized assessment of EFW by US within 7 days, 95% presence of “experienced OB”). 

        • And this is heavily noted in the conclusions of the paper – stating “only centers that can provide OB management as specified by the protocol, including ability to perform a CD within 30 minutes if necessary” should undertake this.

  • Methodologically, this group responded to many criticisms of the Term Breech Trial:

    • An improved randomization scheme that was block-based, stratified by gestational age and parity.

    • Improved use of ultrasound and CTG in labor, as well as higher standard of care at all sites to prevent misappropriation of primary outcome.

    • More explicit counseling – happening weeks before delivery on average, rather than in labor!

  • And finally - and most importantly - this represents a well-selected, high-resource, best-case scenario work.

    • For our US listeners who mostly practice in centers where there is ability to perform cesarean within 30 minutes, the Twin Birth Study included:

      • Twins delivering between 32w0d and 38w6d

      • With EFW estimated by US within 7 days of delivery, ranging from 1500g - 4000g

        • Second twin not significantly larger (with expert opinion putting this around a max of 15% discordance)

      • Ability to perform CD within 30 minutes, and use CTG and intrapartum US

      • With someone with experience and ability to perform breech extraction and internal podalic version available 

Postpartum Care

Here’s the RoshReview Question of the Week:

A 23-year-old G1P1001 woman presents to the office for her routine postpartum visit. She is 6 weeks postpartum status post vaginal delivery of a healthy infant. Her pregnancy was complicated by diet-controlled gestational diabetes mellitus and obesity. She completes a 2-hour glucose tolerance test using a 75 g glucose load. Her fasting plasma glucose level is 85 mg/dL, and her 2-hour plasma glucose level is 130 mg/dL. Which of the following is the most likely diagnosis?


More Reading: ACOG Committee Opinion 736 from May 2018: Optimizing Postpartum Care 

Why Do We Care About PP Care? 

  • The days/weeks following birth are critical for patient and infant well-being 

    • Multiple physical, social, and psychological changes 

    • Recovery from delivery (either vaginal or cesarean) 

    • Challenges of breastfeeding

    • Lack of sleep, fatigue, pain, stress

    • New or exacerbation to mental health disorders 

    • Urinary or even anal incontinence 

  • Challenges 

    • Fragmented care between pediatric and obstetric care providers: 

      • As an example of what babies get: day 1-2 of life, day 3-5 of life, 1 month check up, 2 month, 4 month, 6 month, 9 month, and 12 month 

      • Just for well babies! 

      • If other complications, maybe more visits! 

    • Long time before we see our patients 

      • Usually, will see them at 4-6 weeks postpartum 

      • Initial lack of attention to maternal health needs - more than half of pregnancy related deaths occur after the birth of the infant! 

      • Instead of ongoing care, we have fragmented, one or two time visits 

A Call to Action 

  • Because of these issues, ACOG has wanted to increase awareness for the fourth trimester 

  • What we currently have - (FYI, this is me ranting about our current system because I’m a raging socialist. Feel free to chop as much as needed) 

    • 4-6 week visit x1 

    • Edinburgh postpartum depression screens to try and catch postpartum blues, but administered in the hospital and again at 4-6 weeks - can miss depression in the first month after birth

    • With COVID, often not letting family members or infants come to postpartum visits 

    • All pregnant patients receive health insurance through Medicaid, but this insurance stops at 6 weeks postpartum 

    • The US is also one of 7 countries in the entire world without paid maternity leave (WTF) 

    • On average, countries that provide paid maternity leave pay 77% of previous pay 

    • The UK has paid maternity leave minimum of 39 weeks. Most places have a minimum paid maternity leave of 12 weeks to a full year, and on average, globally, the paid maternity leave is 29 weeks. Average paternity leave is 16 weeks 

NY Times

  • What this results in

    • Less attendance of postpartum visits

      • Not wanting to use accrued family leave/sick days for appointments 

      • Unable to find someone to care for themselves/their infants to go to appointments 

      • Results in as many as 40% of patients don’t go to postpartum visits 

      • 23% of employed women return to work within 10 days postpartum, and an additional 22% return to work between 10-40 days pp!!!!! 

    • Less anticipatory guidance

      • With decreased time during pregnancy (due to covid) and also with not going to postpartum visits and not having PP visits soon enough → on a national survey, less than ½ of patients attending a PPV reported the received enough info about depression, birth spacing, healthy eating, importance of exercise, changes to their sexual response and emotions 

      • In randomized controlled trial, 15 minutes of anticipatory guidance before discharge, followed by phone call at 2 weeks reduced symptoms of depression and increased breastfeeding duration through 6 months among black and hispanic women  

    • More maternal morbidity and mortality 

  • What we want (and ACOG wants) 

    • Timing of postpartum visit be individualized and woman centered 

    • Initial assessment within 3 weeks postpartum to address acute issues 

    • Follow this up with ongoing care as needed - ie. well woman visit no later than 12 weeks after birth 

    • Insurance should allow for this care (don’t take it away after 6 weeks!)

      • American Rescue Plan Act - allows states to extend Medicaid coverage for pregnant people from 60 days to 1 year postpartum 

      • As of 4/2022: currently in effect for 13 states 

      • 14 states and DC planning to implement a 12 month extension 

      • 4 states with limited overage extension approved or proposed 

      • 4 states pending legislation to seek federal approval 

What should we be doing then for PP Care? 

  • Start early - begin anticipatory guidance even in prenatal care! 

    • Develop a postpartum care plan (Table 1 - can go through some of these things) 

    • Reproductive life planning 

      • Review desire for future pregnancies 

      • Counsel pregnancy spacing (avoid short interval pregnancy, within 6 months, and risks and benefits of pregnancy sooner than 18 months) 

      • Review contraception options if desired 

    • Build a support system 

      • Review: who will provide social and material support? Ie. family, friends

        • Can get social work involved if needed  

      • Identify providers that patient can call with questions

        • Primary care provider, Ob provider, psychiatry provider 

        • Pediatric provider 

        • Lactation support 

        • Care coordinator/case manager 

        • Home visitation 

        • Provide phone numbers or other contact information  

  • Intrapartum to Postpartum Care

    1. Early postpartum period contains substantial morbidity 

    2. Blood pressure evaluation no later than 7-10 days postpartum for those with hypertension

      1. Great studies regarding postpartum blood pressure checks via text message - easy for both patients and clinicians

      2. Decreases usage of emergency rooms 

      3. Those with severe hypertension should be seen within 72 hours!  

    3.  In person follow up earlier for patients with complications such as: 

      1. Cesarean section or perineal wound infection 

      2. Lactation difficulties 

      3. Chronic conditions like seizures that may require postpartum medication titration 

    4. WHO recommends follow up of all women and infant dyads at 3 days, 1-2 weeks, and 6 weeks - we don’t do this in the US! 

    5. Based off of this ACOG recommends first contact within 3 weeks (does not have to be in person, can be by phone) 

    6. Can set up postpartum care either in the prenatal period (we will usually make pp appointments for patients in the hospital or right before delivery) 

  • The components of postpartum care - these were really good from ACOG, so thought I would include 

    1. Mood and emotional well-being 

    2. Infant care

    3. Sexuality, contraception, birth spacing 

    4. Sleep/fatigue 

    5. Physical recovery 

    6. Chronic disease management 

    7. Health maintenance 

What about birth trauma? 

  • Remember that trauma is in the eye of the beholder

    • Many healthcare providers may not even be aware that their patient experienced trauma 

    • Allow patients to ask questions about their labor, childbirth course and review any complications 

    • Complications should be reviewed and how they can best be avoided in next pregnancy if possible (ie. reduce risk of preterm birth, preeclampsia)  

    • Referral to support group, mental health care specialist 

  • Pregnancy loss 

    • Remember to always review someone’s labor course and delivery!

      • May sound basic, but there are times when people miss a cesarean scar or even that someone had a pregnancy loss and congratulate the patient (omg)  

    • Emotional support and bereavement counseling with referrals if appropriate 

    • Review labs and path from loss 

    • Order other labs if needed (look at our stillbirth episode) 

Transition to ongoing care 

  • Refer to ongoing well woman care within 12 weeks 

  • Make sure that there is a good transition for birth control/continued prescriptions

    • Write this out in your notes/recommendations 

    • Many patients all of a sudden don’t have access to get their birth control because their obstetrician or midwife isn’t seeing them anymore 

    • Or, if their OB started them on an antidepressant, all of a sudden, they don’t get scripts anymore because they are not longer postpartum - make sure to help patients get appointments to their PCP or mental health care and transition them!
