    Referral template to paeds - from OBGYN HO prespective

    HUSM obgyn paeds referral template:just a note for me to remember when needed to be used. 

    This template is also being passed down by seniors, grateful to those who started this. 

    It is too common that we are being scolded for not presenting detail enough while referring case to MO paeds. This will be especially useful for those who are like me, went to OBGYN posting first before paeds, and have no idea what to do. 

    Good luck guys!

    It is part malay and english, so those who dont understand malay it's time to pick up a new language. 

    **especially those who graduated oversea. 


    Paeds referral

    Summary:

    Dr, saya HO(houseman) xxx, from LR(labor room)/ward xx nak refer baby of 


    (example of problems)

    i. M(maternal) GDM on insulin/metformin

    ii. M PROM > ? hrs

    iii. M GBS positive

    iv. Macrosomic baby (> 4.5kg)

    v. Low birth weight baby (<2.5kg)

    (Example notes to write in record)


    This is baby of ___.

    Baby boy/girl, currently _ hours of life. 

    Born via SVD at _weeks __days POA(period of amenorrhea)/POG(period of gestation) 

    with BW(birth weight) _kg & Apgar score __ at 1 min 


    Antenatally mother have

    1.

    2.

    3.

    4. 


    On examination of baby

    - Baby pink, active on handling

    Some details to take note for each case:


    1. Low birth weight(LBW) baby

    • LBW<2.5kg

    • ELBW <1kg (E: extreme)

    *Not all LBW are SGA (Small Gestational Age)

    *It can be AGA (Appropriate for Gestational Age)

    So plot growth chart if has LBW baby


    SGA : wt <10th centile

    Symmetrical SGA : all components <10th centile

    Asymmetrical SGA : wt (weight) <10th centile, COH (circumference of head) and length almost achieve centile for the gestational age

    Induction of labor - Obstetric

     

    Here is the summary of IOL and more information do scroll down to understand further details. 

    Notes:
    • IOL : Induction Of Labor
    • GDM: Gestational Diabetes Mellitus
    • PROM: Premature Rupture of Membrane
    • IUD: Intrauterine Death
    • IUGR: Intrauterine Growth Restriction
    • LGA: Large Gestational Age
    • NRVE: Next Review Vaginal Examination
    • NRC: Next Review Contraction
    • LSCS: lower segment caesarean Section

    Bishop score

    Balloon Device

    Inflated bulb of a Foley catheter exerts pressure to the internal os of the cervix which then stretches the lower uterine segment and stimulates release of prostaglandin (PG)

    Contraindicated in patients with low-lying placenta

    The catheter is left in place until it falls out spontaneously/24 hours have elapsed


    Pharmacological approach



    Artificial Rupture of Membrane

    - one of the ways of induction of labor (IOL), usually to speed up the process of labor
    - only been done when cervix is dilated to >4cm or > 3cm if indicated
    - and baby's head firmly decended to the pelvis.

    Contraindication:

    1. Bishop score<6
    2. breech
    3. grandmultipara
    4. preterm
    5. high presenting head
    6. polyhydramnious - if rupture is needed: need to have controlled ARM
        - where assistant is needed to control the baby's position to avoid baby from changing position

    Risk: 

    1. cord prolapse: if the baby head is not engaged well, and membrane rupture causing the cord to slip down below the baby's head.
    2. Sepsis: when the labor time is prolonged
    3. Failure of induction
    4. increase risk of fetal distress

    Before you start ARM procedure, always remember to check 

    • Patient's name, and registration number
      • confirm Antenatal history
    • Are they indicated for ARM?
      • or any contraindications
      • check if any oligohydramnious / polyhydramnious - as baby could change position if not stabilised
    • How is the position of the mother and Baby?
    • Ensure there is an IV line set already with IV drip

    • Vaginal Examination: any cord/ placenta
      • Cx and Os dilation, Station
    •  Ensure mother is not having contraction when you wanted to rupture the membrane
      • only rupture when there is no contraction 
      •  to avoid causing chorioamnionitis (acute inflammation of the membranes and chorion of the placenta, typically due to ascending polymicrobial bacterial infection in the setting of membrane rupture.)
        






    Post ARM

    • monitor mother's 
      • vital sign
      • contraction
      • progress of labor 
        • Vaginal examination 4hrly. 
        • time contraction (NextReview of Contraction): 2hrly 
    • baby's fetal heart rate

    Abnormal uterine bleeding

    One of the most common disease in gynae ward

    Definition 

    - infrequent episode of bleeding(oligomenorrhea)
    - prolong duration of menses (longer than 7 days)
    -  excessive flow of menses (soaking>1 every 1-2hr, passing blood clot>50cents, soak pads for >2-3hrs in a row)
    - coital bleeding
    - intermenstrual bleeding

    Risk factor: 

    Palm coin mneumonic


    Mx:

    - make sure you asked the menstrual history throughly, it would aid in differential diagnosis and approach. 
    • age
    • cycle length
    • duration of bleeding
    • flow: heavy, medium, light
    • any contraceptive use? 
    • when is the last mentrual date (LMP)
    • any dysmenorrhea
    • any abortion done before/ miscarriage/ last SI(sexual intercourse)
    • hx of anemia/ 
    • any family hx of cancer/ social hx/ past medical hx
    1. v/s
    - BP (low?),
    - PR(tachy?)
    - temperature
    - SPO2
    - physical examination: pallor? bruising?

    2. Set up
    - call for help
    - 2 large bore IV branulla
    - GXM 2pint standby
    - send FBC, coag, 
    - O2 supply
    - pelvic ultrasound

    3. ensure hemodynamicallly stable
    - IVD run fast (hartman+NS)
    - T. tranxenamic acid
    - IV tranxenamic acid
    - if its retained products of conception: attempt to remove if possible (D+C), if unable, arrange for ERPOC
    - pregnancy test if possible.
