Hypotension in Pregnancy

Is it normal, or is it shock?

HR by5-15 bpm

MAP by10-15 mmHg

Blood vol by 1L

Hgb by1-3 mg/dL

Patient Positioning

Does Pelvic Position Matter?

Where is the Max IVC diameter?

Supine 24%LLT 48% RLT 28%

No correlation to patient age, BMI, EGA

Hypovolemia:

Pump Failure: Obstruction:

Should we consider a “P-RUSH” in the hypotensive pregnant patient?

Summary

• Stay Calm (at least on the outside!)

• Mobilize your resources, assign roles

• Proceed with ABCs and consider modifications

• Consider using ultrasound to help guide therapy

• Most treatments are the same as the non-pregnant patient!

• Be ready to perform perimortem c-section within 4 minutes in appropriate patients
