Study summary

In some centres, women are routinely given a course of antibiotics postnatally if ragged placental membranes were present at delivery. The investigators examined the necessity such an intervention.

Read the detailed description

Postpartum endometritis resulting in sepsis remain one of the leading cause of maternal mortality in developing countries. Ragged placental membrane is a risk factor for endometritis and is not infrequently encountered. Several hospitals in Malaysia, largely those geographically-removed currently practice administering prophylactic antibiotics for women with ragged placental membranes. The aim is to reduce the risk of postpartum endometritis in a subgroup of women who may present in dire straits. The investigators sought to examine the necessity of such protocols.

Inclusion criteria

All women who delivered vaginally beyond 24+0 weeks of gestation and were found to have ragged or retained placental membranes immediately after the third stage of labour were invited to participate in the study.

Exclusion criteria

Exclusion Criteria:

  1. Fever, within 5 days preceding delivery (Axillary temperature > 37.5oC on 2 or more occasions at least 1 hour apart or temperature > 38oC on one occasion). This also includes intrapartum fever.
  2. Required oral or intravenous antibiotics for any other obstetric-related (ex. third or fourth degree tears, preterm prelabour rupture of membranes) or non- obstetric related (ex. pneumonia, acute pyelonephritis) reasons
  3. Prolonged rupture of membrane (>18 hours)
  4. Retroviral disease, on long term oral or parenteral or receiving other forms of , including chemotherapy within the last one year.
  5. Vaginal delivery for an intrauterine death
  6. Penicillin allergy
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Study arms

  • Active comparator
    Prophylaxis

    Current protocol of administering antibiotics maintained

    Drug: Prophylactic antibiotics

  • Active comparator
    No prophylaxis

    Antibiotics withheld, with appropriate observation and follow up

    Other: No prophylaxis (Amox-clav withheld)

Interventions

  • DrugProphylactic antibiotics

    Amox-clav given to eligible women as per existing protocol, which is 625mg three times a day, for a week

    Also known as: Amox-clav given as per protocol

  • OtherNo prophylaxis (Amox-clav withheld)

    Withholding Amox-clav, which is the current local practice for women with ragged placental membranes. This was replaced with appropriate counselling on signs and symptoms of endometritis, when and where women should present if the symptoms above occur. A follow up phone call was performed at 2 weeks and 6 weeks postpartum to ascertain well-being of patients

    Also known as: Expectant management

What researchers measure

Primary outcomes

  1. Incidence of postpartum endometritis

    Postpartum endometritis is defined as follows, when presenting anytime within 6 weeks postpartum 1. Fever (Axillary temperature \> 37.5 degrees Celcius on 2 or more occasions at least 1 hour apart or temperature \> 38 degrees Celcius on one occasion), occurring in the absence of apparent source of infection or alternative foci of infection. 2. Increasing lochia loss or offensive lochia. 3. Lower abdominal pain or suprapubic tenderness on palpation. The diagnosis is further supported by the following: 1. Elevated total white cell count \> 11.0 x 109 cells/L 2. Positive genital swab culture. Incidence is calculated as follows: Number of patients diagnosed with endometritis in each arm/total number of patients allocated to each arm

    Time frame: 6 weeks postpartum

Secondary outcomes

  1. ICU admission rate

    ICU admission as a result of endometritis. It is measured as follows: a. ICU admission rate in prophylactic antibiotic group= (Number of patients requiring ICU admissions and given antibiotic prophylaxis, regardless of duration/total number of patients given antibiotics prophylaxis ) a. ICU admission rate in "no prophylaxis" group = (Number of patients requiring ICU admissions and NOT given antibiotic prophylaxis, regardless of duration/total number of patients NOT given antibiotics prophylaxis)

    Time frame: 6 weeks postpartum

  2. Rate of surgical evacuation of retained products of conception

    Surgical procedure required as a result of ragged placental membrane or its complications. It is calculated as follows 1. Surgical evacuation of retained products of conception in prophylaxis group= (Number of patients requiring surgical procedure and given antibiotic prophylaxis, regardless of duration/total number of patients given antibiotics prophylaxis ) 2. Surgical evacuation of retained products of conception in "no prophylaxis" group= (Number of patients requiring surgical procedure and NOT given antibiotic prophylaxis, regardless of duration/total number of patients NOT given antibiotics prophylaxis )

    Time frame: 6 weeks postpartum

  3. Rate of Blood transfusion

    Pack cell transfusion required as secondary to a complication from ragged placental membranes. This can be due to postpartum endometritis or surgical evacuation. It is calculated based on the number of patients requiring transfusion. The number of pack cells required per patient would be also be described. 1. Blood transfusion in prophylaxis group= (Number of patients requiring pack cell transfusion and given antibiotic prophylaxis, regardless of duration/total number of patients given antibiotics prophylaxis ) 2. Blood transfusion in "no prophylaxis group"= (Number of patients requiring pack cell transfusion and were NOT given antibiotic prophylaxis, regardless of duration/total number of patients NOT given antibiotics prophylaxis )

    Time frame: 6 weeks postpartum

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 12, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
