IS IT THIS? - reference only, to read alongside your own examination
  SYMPTOMS - what the patient reports (9)
    - Run the standard trauma algorithm: primary, secondary and tertiary survey
    - Vital signs shift through normal pregnancy, so read them against pregnancy values
    - Ask every woman of childbearing age whether pregnancy is possible and send a beta-hCG
    - Ask about previous preterm labour, placental abruption and placenta praevia
    - Get obstetric help urgently, above all in the second or third trimester
    - Bleeding from the vagina before labour is always abnormal  [vaginal bleeding]
    - It may mean abruption, early labour, the cervix opening early, or placenta praevia
    - Cloudy, white or green discharge suggests the membranes have gone, raising infection risk
    - Contractions after an injury are a concerning finding  [uterine contractions]
  SIGNS - what you find (10)
    - Concerning findings: penetrating abdominal injury, vaginal bleeding, ruptured membranes, a
      bulging perineum, contractions or an abnormal fetal heart rate  [uterine contractions ·
      vaginal bleeding]
    - Ruptured membranes risk cord prolapse, an obstetric emergency needing immediate caesarean
    - If the circulation allows, include a speculum examination
    - Palpate for fundal height, which estimates gestation and may be the only clue in an
      unresponsive patient  [loss of consciousness]
    - The uterus rises above the pubic bone between 8 and 12 weeks
    - From 20 weeks it climbs about a finger’s breadth at a time until 40 weeks
    - It reaches the sternum at 36 weeks, then drops as the head engages
    - A fundal height that does not match known dates suggests uterine injury, twins or growth
      restriction
    - Avoid low blood pressure and give oxygen, because the fetus tolerates hypoxia badly
      [hypotension · hypoxia]
    - If rapid sequence intubation is needed, pregnancy calls for lower doses of suxamethonium
  TESTS (12)
    - Fetal heart sounds can be heard with a stethoscope from 20 weeks; before that use a Doppler
    - They are detectable from as early as 12 weeks, usually between 110 and 160 bpm
    - Fetal hypoxia first shows as a fast heart, then slows as oxygen falls further
    - Any sustained rate below 120 bpm means fetal distress, and points to maternal blood loss
    - Past 24 weeks, monitor the fetal heart for 4 to 6 hours after arrival
    - Fear of radiation must not delay the right diagnosis; the mother comes first, not the fetus
    - An abdominal x-ray gives the fetus 0.1 to 0.3 rads; abdominal and pelvic CT gives 3 to 4 rads
    - A pregnancy should accumulate under 10 rads in total, and no one study should pass 5 rads
    - Between 8 and 15 weeks a high dose (>10 rads) may cause growth restriction and brain defects;
      past 15 weeks no dose-dependent effect appears
    - Ultrasound and MRI have no known harmful effect on the fetus
    - Keep eFAST in the secondary survey; it finds blood or air in the chest, round the heart, or in
      the abdomen
    - Radioactive iodine must not be given therapeutically in pregnancy
  IF NOT THIS - what else fits (5)
    - Blunt abdominal trauma heads the listed differential
    - Placental abruption needing emergency management
    - Penetrating abdominal trauma completes the three
    - Free fluid confined to the pelvis on ultrasound is of unclear meaning in pregnancy
    - MRI is safe in pregnancy but often impractical in an emergency, on availability and time

Rx: Prevention of Rh iso-immunisation  |  Main treatment

PREVENTION OF RH ISO-IMMUNISATION
1. RHO(D) IMMUNE GLOBULIN                                 [1st line]
   Adult    Rh-negative mother only. Under 12 weeks gestation, 150 micrograms. Over 12 weeks, 300
            micrograms. More than that if the feto-maternal haemorrhage is large, which the
            Kleihauer-Betke test measures. - A single dose after the injury, repeated only as the
            Kleihauer-Betke result requires
   Peds     Adult-only condition - paediatric section not applicable
   Source   Pregnancy Trauma - StatPearls - NCBI Bookshelf -
            https://www.ncbi.nlm.nih.gov/books/NBK430926/
   Why      The cited article states that the mother's Rhesus type should be sought, that if she is
            Rh-negative there is a chance of iso-immunisation compromising later pregnancies, and
            that Rh immunoglobulin should be given regardless of mechanism - including a fall from
            standing - because sensitisation occurs at 0.01 to 0.03 mL of fetal blood in 70% of Rh-
            negative patients. It states the amounts by gestational age: 150 micrograms below 12
            weeks, 300 micrograms above, and more where the feto-maternal haemorrhage is marked
            after massive blunt abdominal trauma.
   Caution  EGYPT STOCKS ONLY THE 300 MICROGRAM PRESENTATION. All three registered products -
            RHOGAM, RHOPHYLAC and WINRHO SDF - are 300 micrograms; the 120 microgram WINRHO vial is
            withdrawn and there is no 150 microgram product. Below 12 weeks the article's amount
            cannot be dispensed as written here, and the 300 microgram dose is what is available.
            IT IS FOR AN RH-NEGATIVE MOTHER AND NOBODY ELSE. Check the blood group first. Giving it
            to an Rh-positive mother is useless and not harmless.
            THE KLEIHAUER-BETKE TEST SETS THE DOSE UPWARDS, NOT THE PRESENCE OF BLEEDING. The
            article notes the test only detects a feto-maternal haemorrhage above 5 mL while iso-
            immunisation can happen at 0.01 mL, so it is used to decide HOW MUCH extra is needed,
            not WHETHER to give the first dose.
            A FALL FROM STANDING COUNTS. The article names it explicitly. The threshold for giving
            this is far lower than the threshold for admitting the patient.
            TRANEXAMIC ACID IS SAFE IN SEVERE HAEMORRHAGE WITHIN 3 HOURS OF THE INJURY, the article
            states, and blood products should be given in a 1:1:1 ratio as for a non-pregnant
            patient. It gives no amount for tranexamic acid, so none is written here.
            TETANUS TOXOID IS SAFE IN PREGNANCY, the article states. It also names the antibiotics
            to avoid on teratogenic grounds: aminoglycosides, quinolones, metronidazole and
            sulfonamides. Enoxaparin and heparin are safe for thromboprophylaxis because they do not
            cross the placenta.
            THE MOTHER IS RESUSCITATED FIRST. The article asks for the uterus to be displaced off
            the vena cava with a wedge or roll, and warns that vasopressors further compromise
            placental blood flow.

MAIN TREATMENT
2. REFERRAL & SAFETY-NETTING (NO DRUG THERAPY)            [1st line]
   Adult    Trauma during pregnancy (falls, road traffic accidents, domestic violence) requires
            urgent assessment of both mother and fetus; the GP recognises and refers to obstetric
            emergency care. - Refer, with advice

   Why      Trauma during pregnancy (falls, road traffic accidents, domestic violence) requires
            urgent assessment of both mother and fetus; the GP recognises and refers to obstetric
            emergency care.
   Caution  Abdominal trauma in pregnancy with bleeding, contractions, or reduced fetal movement
            needs immediate obstetric referral for possible placental abruption.
            The drug rows above are what the treating service gives. They are here so that the
            referral is an informed one and so the GP can recognise the regimen the patient comes
            back on - not as permission to start it without the referral.
