The catheter is also too thick for the pediatric patient's bronchus.
Dr. Liu Yu reminded Student Xie again why this is important.
The obstetrician self-made a balloon in a fully visual environment, where they could clearly see and determine the exact size and shape of the balloon to best fit the patient's uterine wall for hemostasis.
Otherwise, it's necessary to use a balloon like those in interventional endoscopy surgery, similar to the initially invented obstetric hemostatic balloons and the various balloons currently in use, each with a tube connecting to the balloon slowly pressurizing it. If the balloon is too big or too small, it won't work to stop the bleeding.
What is the premise of hemostasis by pressure within the cavity? It is adequate packing.
Because the doctor's hand cannot reach inside, to fully apply pressure on the bleeding surface, it can only be done by employing the natural volume reduction capability of the cavity to apply pressure to the bleeding surface.
