A researcher is bitten by a shark scuba diving in the South Pacific. A tourniquet is placed and left on for the 11 hour boat trip to Guam. Doctors want to amputate the arm. In a last ditch effort she calls her friend Dr De Silva in Gaza who happens to have WiFi briefly. He calls me who happens to be on night shift. I advise pumping the brakes on amputation because she is at the facility where they have a hyperbaric chamber…the hyperbaric doctor is consulted…
