Episode 935: Pregnancy Extremis - TOLDD

Contributor: Aaron Lessen MD

Educational Pearls:

• Pregnant patients at high risk of cardiac arrest, in cardiac arrest, or in extremis require special care

• A useful mnemonic to recall the appropriate management of critically ill pregnant patients is TOLDD

• T: Tilt the patient to the left lateral decubitus position

• This position relieves pressure exerted from the uterus onto the inferior vena cava, which reduces cardiac preload

• If the patient is receiving CPR, an assistant should displace the uterus manually from the IVC towards the patient's left side

• O: Administer high-flow adjunctive oxygen

• L: Lines should be placed above the diaphragm

• Lines below the diaphragm are ineffective due to uterine compression of the IVC

• May consider humeral interosseous line vs. internal jugular or subclavian central line

• D: Dates should be estimated

• > 20 weeks, can consider a resuscitative hysterotomy (previously known as perimortem c-section) to improve chances of survival

• The uterus is palpable at the umbilicus at 20 weeks and 1 cm superior to the umbilicus for every week thereafter

• D: Call the labor and delivery unit for additional help
