Cascade of Intervention in Childbirth
What is the "cascade of intervention?"
What is an example of the cascade of intervention?
How can I limit the problem of a cascade of intervention?
Many maternity care interventions have unintended effects during labor and birth. Often these effects are new problems that are "solved" with further intervention, which may in turn create even more problems. This chain of events has been called the "cascade of intervention."
This chain of events can change the course of a woman's labor in important ways, yet women and their partners are often unaware that many routine interventions can lead to a cascade of unplanned experiences and unwanted side effects.
The maternity practices that can lead to a cascade of intervention include:
In many instances, these practices cause problems because they disrupt the normal physiology of pregnancy, labor and birth — for example, by:
A variety of interventions — such as continuous electronic fetal monitoring and intravenous fluids — are widely used with epidurals to monitor, prevent or treat these effects. And others become more likely, including use of synthetic oxytocin to strengthen contractions, use of a urinary catheter to empty the bladder, and use of a vacuum extractor or forceps to help move the baby out. These in turn may have side effects that lead to the use of other interventions.
The impacts can also extend to babies. For example, epidurals increase a woman’s likelihood of developing a fever; if a mother has a fever, caregivers worry that her baby may have an infection. Though few babies whose mothers have an epidural associated fever do in fact have an infection, as a precaution these babies often have blood tests and are treated with antibiotics just after birth. They may also be observed in a special nursery, which can interfere with bonding and breastfeeding.
This chain of possible effects from epidural and other interventions shows the importance of making careful, informed maternity decisions.
Unfortunately, it is impossible to fully and accurately know in advance the course of a decision, and the degree to which other interventions and their effects will come into play. The best way to limit the problem of a cascade of intervention is to become informed, get all of your questions answered, set your goals and plans, and avoid interventions with the potential for harm, whenever possible.
The following may help you avoid unnecessary interventions:

Listening to MothersSM III is the third national survey exploring women’s experiences in pregnancy and childbirth. Commissioned by Childbirth Connection, conducted by Harris Interactive, and funded by the W.K. Kellogg Foundation, the survey polled 2,400 women who gave birth in U.S. hospitals from 2011 to 2012. Results show that medically intensive experiences are typical, and evidence-based practices are underutilized. Childbearing women need better support and knowledge to navigate their maternity care.
