Managing Acute Menorrhagia

November 25, 2015 · by drmarlenepearce

This week (after a very long break) we get back to business. We’ll take you through the diagnosis, management and investigation of acute menorrhagia.

Take Home Messages:

Acute Menorrhagia can be severe enough to create haemodynamic instability, assess for shock first.
Always perform a B-hCG to exclude pregnancy/miscarriage
Be sure to exclude a pelvic infection in your work-up
Consider inherited platelet dysfunction or coagulopathies in the adolescent with new menorrhagia
Consider endometrial hyperplasia or cancer in the woman over 35
Medical management may include NSAIDs, high-dose Progesterone, Tranexamic Acid
Surgical management may include Dilation & Curettage

Bleeding in Early Pregnancy: Diagnosing Miscarriage

November 10, 2014 · by drmarlenepearce

This week we discuss bleeding and pain in early pregnancy, and how to diagnose miscarriage.

Take Home Messages:

Miscarriage occurs in 1 in 5-6 confirmed pregnancies.
A pregnancy that has not yet been sighted on USS remains a ‘Pregnancy of Unknown Location’ and remains a possible ectopic pregnancy until proven otherwise.
Serial B-hCGs can be helpful in guiding your clinical decision making, however you cannot ‘locate’ a pregnancy with a blood test alone.
In the symptomatic patient, a falling, plateauing or rising B-hCG can ALL be associated with an ectopic pregnancy – these must be followed until an ectopic pregnancy can be diagnosed or excluded.
A rise of B-hCG in 48hrs of > 63% is relatively reassuring for an ongoing intrauterine pregnancy, make sure to confirm it with an USS as soon as you can.
The ultrasound diagnosis of both a blighted ovum and a missed miscarriage (with a foetal pole) have strict criteria – refer ASUM guidelines below.

Quick Start Contraception – It’s Contraception, STAT!

October 15, 2014 · by drmarlenepearce

This week we discuss how to “Quick Start” contraception – on the day your patient requests it.

Take home messages:

Women are at unnecessary risk of pregnancy in the window between ASKING for contraception and STARTING contraception
There are clear protocols for starting contraception at any time in a woman’s menstrual cycle (see links below)
There are no known adverse effects on pregnancy from ordinary hormonal contraceptive methods (except IUDs)
Contraception can be started even if early pregnancy can’t be excluded, with a repeat pregnancy test in 4 weeks time.
Using this algorithm reduces unplanned pregnancies in high risk groups.

LARC Contraception Methods – A Superior Choice

September 21, 2014 · by drmarlenepearce

This week, we discuss the benefits of Long Acting Reversible Contraceptive (LARC) methods, including IUDs and Implants.

Why are we so keen on LARC methods? Because they have a significantly higher continuation rate, higher satisfaction rate, and lower unplanned pregnancy rate than other methods (COCP, POP, DMPA). We also challenge the historical misconceptions regarding the use of IUDs in nulliparous women, and discuss how they are a safe first line option, endorsed by both RANZCOG and family planning groups in Australia.
