Lengthy bernese PAO surgery results in serious blood loss — 6 notes


A recent study shows that bernese periacetabular osteotomy, aimed at reducing hip pain, often causes tremendous blood loss in patients.

Here are six things to know:


1. The study involved 41 patients who underwent bernese PAO for their symptomatic acetabular dysplasia.


2. The researchers found that on average, patients lost 30.3 percent of their blood volume during the surgery.


3. Factors such as arthrotomy, male gender, femoral head-neck osteochondroplasty, labral procedure and age reacted poorly with the surgery's length, ultimately harming the patient.


4. The researchers recommend that before undergoing bernese PAO, patients use hypotensive anesthesia and tranexamic acid to help minimize blood loss during the surgery.


5. Eduardo N. Novais, MD, Patrick M. Carry, Lauryn A. Kestel, Jason Koerner and Gee Mei Tan, MD, conducted the study.


6. Bernese PAO is an operation aimed at reducing hip pain and improving patients' ability to function with symptomatic dysplastic hips.
