Four surgeries were completed before noon, each surgery not exceeding an hour.
In order to avoid damaging the quadriceps, tourniquets weren't used in any of the surgeries. Low pressure anesthesia was used to keep blood pressure below 90/60mmHg, and water pressure inside the knee joint was maintained at 120mmHg by a pump.
In this way, even without the use of tourniquets, a bloodless surgical field could be achieved.
The damage that a tourniquet can cause to the quadriceps may be a non-issue for the general population, but for professional athletes, it can greatly influence recovery time.
Maintaining 120mmHg pressure in the knee joint can easily cause interstitial edema if the doctor lacks experience. This could trigger compartment syndrome and lead to severe consequences.
With the surgeries over, the nurses, Linna and Jenny, both heaved a sigh of relief.
