EDAIC Obstetric Anesthesia and Analgesia 3

Question 1

What is the recommended left lateral tilt angle for a term pregnant patient undergoing general anesthesia to prevent aortocaval compression?

Accepted Answer

15-30 degrees

Answer

Left lateral tilt of 15-30 degrees (typically using a wedge under the right hip) effectively displaces the gravid uterus off the aorta and inferior vena cava.

Question 2

A parturient receives magnesium sulfate for eclampsia prophylaxis. Which finding would prompt immediate magnesium discontinuation?

Accepted Answer

Respiratory rate of 10/min

Answer

Respiratory rate below 12/min indicates respiratory depression from hypermagnesemia and requires immediate cessation and calcium gluconate administration.

Question 3

Which statement about remifentanil patient-controlled analgesia (PCA) for labor is CORRECT?

Accepted Answer

It carries risk of maternal apnea requiring monitoring

Answer

Remifentanil PCA can cause maternal apnea and oxygen desaturation, requiring continuous SpO2 monitoring and 1:1 nursing care.

Question 4

In a patient with placenta previa requiring cesarean delivery, which anesthetic consideration is MOST important?

Accepted Answer

Prepare for massive hemorrhage and have blood products ready

Answer

Placenta previa carries high risk of massive hemorrhage; large-bore IV access, crossmatched blood, and cell salvage should be prepared before incision.

Question 5

What is the most common cause of maternal death directly attributable to anesthesia in obstetrics?

Accepted Answer

Failed intubation with hypoxia

Answer

Failed or difficult intubation leading to hypoxia remains the leading anesthesia-related cause of maternal mortality, driving the preference for regional techniques.
