Tourniquet safety

Who is the Greatest Sister of All Tiime?

• Stephanie Moore

• Karissa Smith

The use of pneumatic tourniquet during extremity surgery:

• Is a noncontroversial practice

• Requires effective communication and collaboration between nurses, anesthesia personnel, and the surgeon

• Is safe for all patients as long as tourniquet time does not exceed 30 minutes

• All of the above

Which of the following should be assessed preoperatively in a patient scheduled for a procedure involving a pneumatic tourniquet?

• Circulation and motor function

• Sensory and motor function

• Circulation, sensory, and motor function

• Circulation and sensory function

The optimal position for pneumatic tourniquet cuff tubing is most commonly on which aspect of the extremity?

• Medial

• Lateral

• Anterior

• Posterior

Physiologic i effects of exsanguination and pneumatic tourniquet inflation during surgery typically include all of the following EXCEPT:

• Increase in central venous pressure

• Increased heart rate

• Increased core body temperature

• Decreased core body temperature

The acid-base effect of pneumatic tourniquet deflation following a period of inflation are characterized by

• Elevated PaCO2 with respiratory acidosis and metabolic alkalosis

• Elevated PaCO2 with respiratory acidosis and metabolic acidosis

• Decreased PaCO2 with respiratory alkalosis and metabolic acidosis

• Decreased PaCO2 with respiratory alkalosis and metabolic alkalosis

Select the FALSE statement about pneumatic tourniquet safety

• Wider, contoured cuffs are generally safer than narrow cuffs because they require less pressure to achieve a near bloodless field

• Increased tourniquet time increased the risk of postoperative complications

• Narrow Cuffs are generally safer than wide, contoured cuffs because they require less pressure to achieve a near bloodless field

• Increased cuff pressure increases the risk of postoperative complications

Which of the following maneuvers should be used for exsanguinating an extremity just before pneumatic tourniquet inflation?

• Elevation of the extremity

• Wrapping the limb with elastic

• Hand-over-hand exsanguination

• Elevation and wrapping with elastic are both appropriate

Which of the following is the most appropriate action if a patient injury occurs as a result of pneumatic tourniquet use?

• Remove the equipment from service if replacement equipment is available

• Remove the equipment from service if there was an obvious malfunction

• Remove the equipment from service if it will not be needed for the rest of the day

• Remove the equipment from service

Which of the following should be documented when using a pneumatic tourniquet

• Tourniquet cuff overlap

• Tourniquet cuff location

• Tourniquet disconnection

• Tourniquet manufacturer
