You are 28+2 weeks pregnant. You are very anxious because you have never had bleeding like this before.

Presenting Complaint

Site – vaginal bleeding.
Onset – since around 9am this morning, you noticed after you went to the toilet to pass urine. You have also been experiencing spotting for the last week or so, however nothing as bad as this.
Character – bright red blood, no clots. No vaginal discharge. You put a sanitary pad in your underwear when you noticed the bleed this morning, you’ve replaced it twice since due to blood soaking the pads.

Associated symptoms – no pain.
Associated symptoms – No anaemia Sx - no SOB, pallor, dizziness, collapse or palpitations. No bleeding from anywhere else in the body.

Assessment

Explanation and Further Management

  • Placenta Praevia means the placenta is lying low in the uterus
  • Bleeding comes from seperation of the placenta itself as the lower segment of the uterus forms or from cervical dilation later in pregnancy
  • Blood usually comes from the maternal blood supply
  • It is a serious medical condition and requires close monitoring
  • Emergency delivery (if mother or baby is in haemodynamic distress)
  • Re-scan with elective caesarean section if the placenta remains low
  • Consultant led monitoring, likely as an inpatient due to bleed

Summary

(Grab a coffee…there’s a lot to discuss 👀)

 

Laura was admitted for monitoring due to the volume of her bleed. She remained cardiovascularly stable and CTG readings remained normal. As a result emergency delivery was not indicated. She suffered 1 further bleed whilst straining to lift a chair in her room at 30 weeks. This was treated with successful resusitation and there were no signs of foetal or maternal compromise. Laura remained an inpatient and delivered a healthy baby boy at 37 weeks via semi-elective caesarian section. 

  • Note that a FBC Haemaglobin will not immediately reflect acute blood loss. This is why a history seeking symptoms of anaemia is a key part of any obstetric bleeding history (and in fact, any acute bleeding history). This is especially true as concealed bleeding commonly occurs in obstetric emergencies so true blood loss may be worse than first resported.

  • Estimating blood loss in ml is notoriously difficult so asking about the volume of soiled clothing/bedding/pads can be useful. 

  • In high tension stations like this it is easy to offer false reassurance, remember, you are an FY1. You often won’t know the prognosis of these presentations especially because you will be moving every 4 months on rotations. No doubt a worried actor will ask you if their baby will be okay during the ideas/concerns/expectations section of your history. A good stock sentence when asked “is my baby going to be okay” is something along the lines of “you are in the right place and we are going to take the best care of both you and your baby”. Clearly in real scenarios it is more complex than this, but in an OSCE scenarios this should satisfy the examiners. As a general rule do not be tempted to offer prognosis unless specifically asked in the prompt or you are confident about the answer (e.g. a station about stroke outcomes).

  • Laura (the mother) is Rh+ so a kleihauer test is not required, but this is worth knowing for MCQs. Any rhesus negative (Rh -) mother who has suffered a faetal bleed should receive Anti rhesus D immunoglobulins to stop Rhesus Disease (the kleihauer test helps identify the quantity of Anti-Rh-D-Immunoglobulin required)
