Which medication is commonly used in postpartum hemorrhage management?

• A. Calcium gluconate.
• B. Gentamicin.
• C. Oxytocin.
• D. Insulin.

Answer: (C)

Postpartum hemorrhage is most often caused by uterine atony, meaning the uterus isn’t contracting well enough to compress the vessels at the placental site. The main goal in management is to promote strong uterine contractions to achieve hemostasis. Oxytocin does exactly that by binding to receptors on the uterine smooth muscle and triggering a signaling cascade that raises intracellular calcium, leading to sustained contractions. This makes it the first-line medication used to treat or prevent postpartum hemorrhage.

Calcium gluconate isn’t used for this purpose; it’s given for low calcium states or certain overdoses. Gentamicin is an antibiotic and doesn’t help with controlling uterine bleeding. Insulin is for glucose control and has no role in managing postpartum hemorrhage.
