Medial transposition of the radial nerve for anterolateral plate fixation of the humerus: cadaveric study.

In the operative treatment of humeral shaft fractures the radial nerve may be injured during the reduction of fracture fragments or the application of plate and screws. Also, secondary surgical explorations due to delayed or non-union carry a high risk of radial nerve injury because of the scarring of the neighboring tissue and proximity of the nerve to the implants. Consequently, the need for the transposition of the radial nerve to a safer position arises.

A new method for estimating arterial occlusion pressure in optimizing pneumatic tourniquet inflation pressure.

To reduce pressure-related injuries resulting from pneumatic tourniquet use, the lowest possible inflation pressure is recommended. Arterial occlusion pressure (AOP) is a measure of the cuff pressure required to maintain a bloodless surgical field. However, its determination method is time consuming, requires operator skill, and is therefore seldom used in current practice.

Controlled hypotension and minimal inflation pressure: a new approach for pneumatic tourniquet application in upper limb surgery.

Unlabelled: Minimal inflation pressures are recommended for limb surgery to eliminate complications attributable to high inflation pressures with the pneumatic tourniquets. We applied controlled hypotension and a minimal inflation pressure (CHAMIP) technique to provide a bloodless surgical field. Thirty-six patients scheduled for upper extremity surgery were randomized equally to receive either normotensive anesthesia and conventional inflation pressures or controlled hypotension (systolic arterial blood pressure of 80-100 mm Hg and mean arterial blood pressure >60 mm Hg) and minimum inflation pressures.
