What is the treatment of choice for malignant hyperthermia?

Accepted Answer

Dantrolene sodium IV

Dantrolene sodium prevents calcium release from the sarcoplasmic reticulum, halting the hypermetabolic crisis of malignant hyperthermia.

Question 3

What spinal level should be achieved for effective first-stage labor analgesia with an epidural?

Accepted Answer

T10-L1

Answer

A T10-L1 sensory block covers the uterus and cervix, providing effective analgesia during the first stage of labor.

Question 4

What is the primary risk of using neuraxial opioids for labor analgesia?

Accepted Answer

Maternal respiratory depression and pruritus

Answer

Neuraxial opioids can cause maternal respiratory depression and pruritus due to opioid receptor activation and potential systemic absorption.
