Which nursing interventions would be beneficial for a client who has a postpartum hemorrhage cause by uterine atony?

Learning Objectives and CME/Disclosure Information

ACOG defines PPH as cumulative blood loss ≥ 1,000 mL or blood loss accompanied by signs or symptoms of hypovolemia within 24 hours after the birth process (including intrapartum) regardless of route of delivery. Unfortunately, postpartum hemorrhage (PPH) is still a leading cause of maternal mortality worldwide.  Following this summary, you can find excellent professional resources at the California Maternal Quality Care Collaborative (CMQCC) and ACOG District II Safe Motherhood Initiative sites. 

CLINICAL ACTIONS:

In the setting of PPH, consider the 4 ‘T’s

• Tone (atony)
• Trauma (laceration)
• Tissue (retained products)
• Thrombin (coagulopathy)

Uterine atony is the single most common cause of PPH (70-80%)

• Empty bladder, perform bimanual pelvic exam, remove clots and initiate uterine massage
• There is lack of evidence to determine which specific uterotonics are superior (good and consistent scientific evidence – ACOG level A)
  • Choice at provider’s discretion
• If uterine atony is identified,  the following drugs have been shown to be effective:

NOTE: Contraindications include hypersensitivity to the specific medication

More on Tranexamic Acid (TXA)

ACOG Update (2017)

• In the WOMAN trial (see Related OBG Topics below) women with PPH received
  • 1 g in 10 mL (100 mg/mL) of tranexamic acid intravenously at a rate of 1 mL per min (i.e., over 10 min)
  • If bleeding continued after 30 min or stopped and restarted within 24 h of the first dose, a second dose of 1 g of tranexamic acid could be given
• Tranexamic acid, administered within 3 hours of birth, has been shown to significantly reduce maternal death due to PPH by approximately 30%
• Based on improved outcomes and lack of adverse events including thromboembolism, ACOG has updated the practice bulletin to include the following

Although the generalizability of the WOMAN trial and the degree of effect in the United States is uncertain, given the mortality reduction findings, tranexamic acid should be considered in the setting of obstetric hemorrhage when initial medical therapy fails. (Level B evidence)

World Health Organization Update (2017)

Based on evidence review, WHO also supports the use of tranexamic acid with postpartum hemorrhage

Early use of intravenous tranexamic acid (within 3 hours of birth) in addition to standard care is recommended for women with clinically diagnosed postpartum haemorrhage following vaginal birth or caesarean section (Strong recommendation, moderate quality of evidence)

Administration of TXA should be considered as part of the standard PPH treatment package and be administered as soon as possible after onset of bleeding and within 3 hours of birth

The reference point for the start of the 3-hour window for starting TXA administration is time of birth

If time of birth is unknown, the best estimate of time of birth should be used as the reference point

TXA should be used in all cases of PPH, regardless of whether the bleeding is due to genital tract trauma or other causes

CONSIDERATIONS IN COVID POSITIVE PATIENTS

Tranexamic Acid (TXA)

• COVID-19 appears to be a hypercoagulable state
• TXA can be considered for the treatment of PPH in keeping with guidance for non-COVID-19 patients
• However, ACOG states

because of the possible additive effect of the increased risk of thrombosis from COVID-19 infection and the hypercoagulative state of pregnancy, it may be prudent to consider this increased likelihood of clotting before administering TXA for postpartum hemorrhage

Hemabate

• While Hemabate is not used in asthma due to risk for bronchospasm, patients with COVID-19 have respiratory symptoms consistent with viral pneumonia
• While there is no data specific to COVID-19 and this medication, “Hemabate is not generally withheld” in patients with viral pneumonia

SYNOPSIS:

The key to managing PPH is identifying the severity of the situation early and quantifying estimated blood loss (EBL).  A second large bore (16 gauge or larger) should be placed and Ringers Lactate used to replace blood loss at 2:1 while, simultaneously as the team is notified, medications are administered to the patient and massive transfusion protocol is initiated.  Initiate fundal massage and place a Foley catheter.

KEY POINTS:

• ABCs
  • Airway: Assess and stabilize
  • Breathing: Supplemental oxygen, 5-7 L/min by tight face mask
  • Circulation: do NOT wait for change in vitals
    • Compromised blood volume: pallor, delayed capillary refill and decreased urinary output
    • Late signs: decreased BP and tachycardia
• Consider intrauterine balloon tamponade or compression sutures for refractory atony
• Surgical Interventions may be a life-saving measure and should not be delayed while waiting to correct coagulopathy
• Quantitative measurement of blood loss is more acurate than visual estimation (see ‘Learn More – Primary Sources’ below) and require 2 key elements
  • Direct measurement of blood loss
  • Protocols for collecting and reporting a cumulative record of blood loss following delivery

Note: The FDA, the World Health Organization, and other professional bodies have released an alert following drug-error deaths related to TXA | TXA use during cesarean delivery has been associated with fatal accidental intrathecal administration because the ampoules of local anesthetic and tranexamic acid are similar in appearance | TXA should not be stored on or near an anesthetic trolley
