Eoghan and Marcus discuss obstetric emergencies, and in this episode they cover Cardiovascular Collapse, Resuscitative Hysterotomy, and a lot more.


TAKE-HOME POINTS

CardioVascular Collapse in pregnancy

  • Get Help

  • ABCDE

    • standard principles

    • left-lateral tilt

    • delivering baby will always make things easier for mum - if life-threateningly unwell then best to deliver to remove the additional load.

      • ideally stabilise and deliver in theatre if possible

      • resuscitative hysterotomy may be needed if no gtime to stabilise

  • Potential Diagnoses:

    • CardioVascular - e.g. Cardiomyopathy, MI

    • Massive Blood Loss (may be concealed in abdomen)

    • PE

    • Standard Causes that can occur outside of pregnancy

  • AMNIOTIC FLUID EMBOLISM

    • typically collapse 30-60 minutes after deliver

    • very littel treatment = supportive and hoping the recover

Resuscitative Hysterotomy

  • Timing is important - ideally within 5 minutes of arrest

  • Have an assistant when performing hysterotomy

    • this is your only task (do not be part of ongoing resuscitation)

    • Focus on getting baby out then stitching closed.

  • It is eassier than it sounds!

  • Midline vertical incision best for non-obstetritian

    • Fundus of uterus (top of bump) to symphysis

    • essentially keep going until you reach baby (which you then pull out)

    • As Uterus expands it pretty much ‘shoves everything out of the way’ so you will go through abdominal wall and then arrive at uterus (you won’t damage much else!)

  • The key factor is ‘ not being shy’ and doing it!

    • outcomes for mother are not great but better than not doing it!!

  • Placenta

    • clamp and cut quickly

    • simply scoop it out with your hands immediately

  • Can close the uterus/wound if comfortable to do so, alternatively pack it and await surgeon/obstetritian

  • If output returns, it will bleed heavily so rfemember UTEROTONICS to contract the uterus

  • If thrombolysis has been given, bleeding from Uterus will be less if ‘closed’ so take a 1.0 suture and stitch as best as you can

Post-Hysterotomy

  • This is a highly-emotional state

    • Typically mother and baby will die

    • Everyone was out of their comfort zone, and likely unsuccessful

  • Do a hot-debrief

  • SHould take a break; some may need to go home!

  • Consider follow-up - counselling etc

PRINCIPLES OF MANAGING A PREGNANT LADY WITH A NON-PREGNANCY-RELATED PROBLEM

  • In general: think about what you would do if this patient wasn’t pregnant, and do that!

  • Same rules apply, and best way to get a healthy baby is to treat mum

  • Remember left-lateral position can help

  • DRUGS IN LATE PREGNANCY

    • Typically all emergemncy drugs can be given if mother unwell

    • Priority is to make mum well

    • Avoid warfarin

  • Admitting a pregnant woman with a medical problem

    • No clear rules on this; should be consultant to consultant

    • Where will the patient get the best care? - if pregnancy stable then should probably go to a medical ward

    • remember: Midwives now are often NOT nurse-trained, so not able to look after complex medical problems

PREGNANCY AND MINOR TRAUMA

  • Perceived Foetal movements are unreliable - mother can ‘feel’ movements even when foetus is dead

  • Best methods are:

    • Listening with Doptone

    • CTG

    • Ultrasound

  • In a teriary centre, refer to obstetrics

  • If working in a remoter community, without support, probably best to learn a simple method to provide reasurance (see options above)
