In planning intrapartum analgesia, which complication should be monitored?

• A. Hyperglycemia
• B. Hypotension
• C. Elevated bilirubin
• D. Seizures

Answer: (B)

When planning intrapartum analgesia, the key issue to watch for is maternal hypotension. This is most likely to occur after neuraxial anesthesia (like an epidural or spinal) because the block interrupts sympathetic nerve activity, causing widespread vasodilation and pooling of blood in the venous system. The result is a drop in systemic vascular resistance and venous return to the heart, which lowers blood pressure. If this drop is significant or untreated, uteroplacental blood flow can decrease, risking fetal distress, so close hemodynamic monitoring is essential.

To manage this, you monitor blood pressure frequently—especially right after placing the block—so you can catch a drop early. Positioning matters: place the patient with a left-lateral tilt to relieve any aortocaval compression from the uterus. Ensure reliable IV access and have vasopressors ready (phenylephrine is commonly used as a first-line agent; ephedrine can be used as well). While fluids can help in some settings, modern practice often favors treating hypotension with vasopressors to restore tone quickly, rather than relying solely on volume.

Hyperglycemia, elevated bilirubin, and seizures are not immediate or direct complications of planning intrapartum analgesia. Hyperglycemia relates to metabolic or diabetic conditions, bilirubin to liver or hemolytic issues, and seizures are more aligned with conditions like preeclampsia/eclampsia or rare anesthetic toxicity, rather than a routine planning concern for analgesia.
