Potential for Injury
neuropathies, crush injuries, pressure necrosis, hyperextension, nerve damage
Physiologic changes
CV, respiratory, venous stasis
Anatomic changes
pressure points, motionless
compression of ulnar nerve
caused by pronation of arm, suppination and padding of the elbow helps to prevent this
Brachial Plexus injury
caused by excessive arm abduction or external rotation, excess neck rotation and/or compression b/w 1st rib and clavicle

Principles for selecting Position
1. position must not cause harm
2. adequate exposure for surgeon
3. anesthesia must be able to administer anesthesia and monitor patient
4. based on individual patient requirements.
