A Bakri balloon is a medical device specifically designed to treat postpartum hemorrhage (excessive bleeding after childbirth). It is an intrauterine balloon catheter used to apply direct pressure to the inside of the uterus, helping to control bleeding by compressing the blood vessels and stimulating uterine contractions.
Components and Function (Based on Reference)
As indicated in the provided reference discussing components of the Bakri Balloon system, the inflating system is a crucial part. This system, often signed by a blue arrow in illustrations or demonstrations, is responsible for inflating the balloon.
- Function: The inflating system allows healthcare providers to introduce a fluid (typically sterile saline) into the balloon.
- Mechanism: As the balloon inflates within the uterus, it applies pressure to the uterine walls. This pressure helps to compress bleeding vessels.
- Stimulation: The pressure also stimulates the uterine muscles to contract, further aiding in stopping the bleeding.
- Volume: According to the reference, this system allows for compression and stimulation of uterine contraction by a maximum volume of 500 milliliters.
How the Bakri Balloon Works
Once inserted into the uterus and inflated, the Bakri balloon exerts tamponade pressure against the inner surface of the uterus. This mechanical pressure collapses the blood vessels that are bleeding, particularly at the site where the placenta was attached. The pressure also helps the uterus to firm up and contract more effectively, a natural process that constricts blood vessels and stops bleeding.
Common Uses
The primary use of the Bakri balloon is in the management of intractable postpartum hemorrhage (PPH) that does not respond to initial medical management (like uterotonic medications). It is considered a minimally invasive intervention compared to surgical options and can be a life-saving measure in controlling severe bleeding after delivery.
