Quizplus · Accepted Answer

Pneumatic tourniquets are frequently used for procedures involving the extremities.
Limb exsanguination is achieved by elevating the limb or by wrapping it,distally to proximally,with an Ace or Esmarch rubber bandage before tourniquet inflation.Preoperative assessment of the patient includes determining contraindications for use,including compartment syndrome,McArdle's disease,hypertension,or other vascular problems.Duration of tourniquet inflation should be kept to a minimum.It is recommended in the average,healthy 50-year-old person to apply continuous tourniquet pressure less than 1 hour on the upper extremity and less than 2 hours on the thigh.Tourniquet pressure should not exceed the recommended maximum cuff pressure limits of 300 to 350 mm Hg for the thigh and 250 to 300 mm Hg for the arm and the lower leg.The interval between inflation and deflation should be 5 minutes for every 30 minutes of tourniquet ischemia to minimize detrimental effects on muscle and nerves.Cuffs should overlap a minimum of 3 inches and a maximum of 6 inches;excess overlap can pinch skinfolds.A tourniquet cuff that is too short can loosen after inflation.
