Obstetric Emergancies

Post partum Haemorrhage (PPH)

PPH - is blood loss of 500 mls or more and/or clinical signs of hypovolemic shock

  • Primary - within 24 hours

  • Secondary - 24 hours to 6 weeks following birth

A major PPH is blood loss of 50% of the blood volume within 3 hours of birth

 Causes of haemorrhage

  • Tone (70%) Responsible for majority of haemorrhages

  • Trauma (20%) Perineal or cervical tears

  • Tissue (9%) Retained products (placental tissue or clots)

  • Thrombin (1%) Coagulopathy (haemophilia/warfarin)

 

Plan

  • Lie Flat

  • High flow O2 (15L)

  • Massage uterus - cupped hand circling on the umbilicus (expel clots and ‘rub up a contraction’)

  • ???? Bimanual compression

  • Insert x 2 16G cannula – Consider 1-2 litres IV fluids.

  • Vital signs – Respiratory rate, pulse, BP, O2 Sats

  • Consider - Syntometrine, Misprostol, TXA

  • Transfer into Obstetric Unit or ED - consider pre alert if concerned mum's condition.

  • Estimate blood loss

  • Perineal trauma - apply external pressure directly using a pad/sanitary towel

Maternal Antepartum haemorrhage

PREGNANT AND POST-PARTUM WOMEN MAY APPEAR WELL EVEN WITH SIGNIFICANT BLOOD LOSS

Haemorrhages my be revealed or concealed

  • <20 weeks bleeding - miscarriage, ruptured ectopic pregnancy

  • >20 weeks bleeding - late miscarriage, low-lying placenta, placental abruption, uterine rupture, ruptured vasa praevia

  • From birth to 4 weeks - Tone, Tear, Tissue, Thrombin (Any fresh bleeding after 20

weeks, regardless of amount- RED FLAG)

Ectopic pregnancy is when an egg implants somewhere other then the uterine wall most common between 6-8 weeks gestation.

Signs and symptoms

  • Vaginal bleeding

  • Vomiting and nausea

  • Lower abdominal pain

  • Sharp cramps/one sided pain

  • Pain in neck, rectum or shoulder

  • Feeling faint/collapse

Placental abruptions - when the placenta either is partially or full detaches from the uterine wall

  • Symptoms include vaginal bleeding (may be no blood seen externally), constant abdominal pain and hard rigid abdomen

Placenta praevia - the placenta embeds near to or over the opening of the womb

  • It can cause silent bleeding - vaginal bleeding that is not associated with pain

Cord prolapse

A cord prolapse is when the cord comes before the baby

knee chest position allows gravity to help, stay in this position as long as possible then run to hospital with mum lying on her side if possible put something under her hip

  • Assist mum to wear knickers and a pad to hold cord in place.

  • If too much cord presenting, sling in hammock using a towel to carry to hospital/get to truck

Final breech

Breech is essentially feet or buttocks presenting instead of a head

  • Start timer here

  • Encourage continuous pushing

  • Do NOT wait for contractions as they may have stopped.

  • Prepare firm, flat surface off the floor and warm the room

  • Call for help?

  • Baby needs to be fully out/born in 5 minutes if not run to hospital

  • you want bay bum to mum tum, if not thumps to bum fingers on femurs and rotate

  • if you see a foot/feet presentation run to hospital

ensure you get consent before internal monoverse

Shoulder Dystocia

shoulder dystocia is then the head is born and the shoulders get stuck behind the symphysis pubis

  • request HELP (CCP or more senior)

  • stop pushing

  • prep for resus

  • lay mum flat on her back, bring knees up to her abdomen, then push with the next contraction

  • if that doesn’t work suprapubic pressure

  • then try all 4s

NLS

  • Dry the baby and cover with warm dry towels and hat, if conveying warm the ambulance to the maximum prior to departure

  • as part of birth imminent prep for a resus

  • Open the airway, and assess colour, tone, breathing & heart rate

  • The lungs need to be cleared by some good inflation breaths. If the baby doesn’t do this by crying, give 5 using a bag-valve-mask. Reassess.

  • If no improvement, give 30 seconds of ventilation breaths – 1 second duration, rate 30/minute. Reassess.

  • If no improvement, 30 seconds 3:1 chest compressions, with oxygen. Reassess.

  • If no improvement, continue 3:1, consider hospital, consider drugs, consider SpO2 (right hand). Reassess every 30s
