Oxytocin in Postpartum Hemorrhage
Objective: Oxytocin is for postpartum uterine atony only, after the placenta, the way the protocol writes it. Massage the fundus first. Do not give it while the baby is still inside. This site does not list units.
Why this matters
Oxytocin is for postpartum uterine atony only. Atony is a soft uterus that will not contract. It is the leading cause of postpartum hemorrhage.
Massage the fundus first. A uterotonic, a drug that makes the uterus contract, comes next if you are authorized. Give it after the placenta, the way the protocol writes it. Do not give it while the baby is still inside. The protocol sets the units. This site does not list units.
- Confirm the baby and the placenta are delivered, per protocol. Feel the fundus if you are trained. Massage a soft uterus.
- Give oxytocin intramuscularly or intravenously, per protocol, only for postpartum atony after the placenta. This site does not list units.
- Do not give oxytocin for third-trimester bleeding while the baby is still inside.
Clinical sequence
- Confirm the baby is delivered and the placenta is delivered, per protocol. Feel the fundus if you are trained. Massage a soft uterus. Massage is a procedure, not a suggestion.
- Give oxytocin intramuscularly or intravenously, per protocol, only for postpartum atony after the placenta. This site does not list units. Tranexamic acid does a different job. It stabilizes clot. Oxytocin makes the uterus contract. The protocol may include one or both. Neither replaces massage.
- Do not give oxytocin for third-trimester bleeding while the baby is still inside. Treat shock and go to a hospital that can do obstetrics. Do not pack the vagina. Do not pull the cord.
Teaching points
- Atony: a soft fundus and ongoing bleeding after delivery.
- Massage is a procedure, not a suggestion.
- Oxytocin is the usual first uterotonic in the hospital and in some EMS protocols.
- A placenta still inside, an inverted uterus, or trauma are different pathways. Do not treat those as simple atony. The destination is a hospital that can do obstetrics.
Common errors
- Oxytocin before the baby is delivered.
- Tranexamic acid instead of fundal massage.
- Packing the vagina.
Practice
One-minute check
With a partner: delivered 20 minutes ago, a soft fundus, and pads soaking through. Say the order: massage, medication, and destination.
