Retained Placenta nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Retained placenta is diagnosed when the placenta hasn't delivered more than 30 minutes after the birth of the baby. The bleeding it causes is treated by removing the retained tissue, whether manually or surgically, because oxytocin alone can't control hemorrhage while placental fragments remain attached and preventing the uterus from contracting.
What it is and why it happens
Retained placenta means the placenta has not separated and delivered within 30 minutes of the baby's birth, the standard cutoff used to define the condition. Beyond that window, the risk of postpartum hemorrhage rises sharply because the uterus cannot contract down fully around retained tissue, leaving the placental bed's vessels open.
The three underlying mechanisms are placenta adherens, where the placenta has separated but isn't expelled due to inadequate uterine contractions; trapped placenta, where a separated placenta is caught behind a closed or partially closed cervix; and placenta accreta and its variants, where the placenta has abnormally invaded the uterine wall and cannot separate at all. Distinguishing these matters because accreta typically requires surgical management, while adherens or trapped placenta may respond to manual removal or medication.
How it presents — what you will actually see
The most obvious sign is simply that the placenta hasn't delivered by the 30-minute mark despite expected signs of separation such as a gush of blood, lengthening of the umbilical cord, or a change in uterine shape. In some cases none of these separation signs appear at all, which points more toward accreta than a simple delay.
Bleeding is often the presenting complaint rather than the delay itself: steady or heavy vaginal bleeding with a fundus that won't stay firm, because the uterus can't clamp down around retained tissue the way it does around an empty cavity. Vital signs may show early tachycardia as blood loss accumulates, sometimes before a visible change in bleeding volume makes the severity obvious.
Nursing assessment priorities
Track time from delivery of the baby continuously, since the 30-minute threshold is what triggers escalation to the provider for manual or surgical removal. Assess fundal tone and location, quantify blood loss rather than estimating, and monitor vital signs closely for the tachycardia that precedes hypotension in postpartum hemorrhage.
Look for the classic signs of placental separation, a gush of blood, cord lengthening, and a firmer, more globular uterine shape, and document whether they're present or absent, since their absence supports a diagnosis of accreta rather than a simple delay. Maintain IV access and have blood products available to transfuse if significant hemorrhage develops, given how quickly bleeding can escalate with retained tissue in place.
Interventions and what to do first
The definitive treatment is removing the retained tissue, either by manual placental removal performed by the provider or, if that's unsuccessful or accreta is suspected, surgical intervention. This is the point that distinguishes retained placenta from most other causes of postpartum hemorrhage: oxytocin and other uterotonics support uterine tone once the uterus is empty, but they cannot substitute for removing tissue that's physically preventing the uterus from contracting.
While preparing for removal, the nurse's role includes maintaining IV access, administering uterotonics as ordered to support tone and limit blood loss, monitoring vital signs and blood loss continuously, and preparing the patient and family for the possibility of manual removal, uterine exploration, or transfer to the operating room. Anticipate the need for anesthesia and analgesia, since manual removal is painful and often requires more than local measures.
Complications to watch for
The primary complication is hemorrhage progressing to hypovolemic shock if the retained tissue isn't removed promptly, so ongoing vigilance for tachycardia, hypotension, and rising blood loss is essential throughout. Infection is a secondary concern, particularly if removal is delayed or incomplete, so watch for fever, foul-smelling lochia, and uterine tenderness in the days after.
Uterine perforation is a recognised complication of manual removal itself, given the need to reach into a postpartum uterus, so post-procedure monitoring includes watching for signs of internal bleeding or unexpected pain beyond what's expected from the procedure. Rarely, disseminated intravascular coagulation can develop if hemorrhage is severe and prolonged, which shifts management toward coagulation support alongside hemorrhage control.
Patient teaching before discharge
Explain what happened in plain terms: the placenta didn't come away on its own within the expected time, and it needed to be removed directly rather than being delivered naturally. Reassure the patient that this doesn't affect future pregnancies for most causes, though a history of accreta or significant uterine instrumentation may warrant discussion with her provider about future delivery planning.
Teach the signs of postpartum hemorrhage and infection to watch for at home, heavy bleeding beyond normal lochia, passing large clots, fever, or foul-smelling discharge, and give clear instructions on when to call the provider versus go to the emergency department. If she had significant blood loss, discuss fatigue and the possibility of iron supplementation for postpartum anemia.

Common questions
How long after birth is a placenta considered retained?
More than 30 minutes after the baby is delivered, without full expulsion of the placenta, meets the standard definition of retained placenta. Some providers intervene sooner if active bleeding is present, regardless of the exact time elapsed.
Will oxytocin resolve retained placenta on its own?
Oxytocin supports uterine tone but doesn't remove tissue that's mechanically preventing the uterus from contracting fully. If the placenta hasn't separated or is trapped, manual or surgical removal is needed alongside, not instead of, uterotonic support.
What's the difference between placenta accreta and simple retained placenta?
Simple retained placenta means the placenta has failed to deliver but hasn't abnormally invaded the uterine wall, and it can often be removed manually. Placenta accreta involves the placenta growing into or through the uterine muscle, which usually requires surgical management and carries a much higher hemorrhage risk.
Can a retained placenta happen without any bleeding?
Yes, some cases present with no significant bleeding at all if the uterus maintains some tone despite the retained tissue. Absence of bleeding doesn't rule out retained placenta, and the diagnosis still rests on the 30-minute time threshold and failure of expected separation signs.
