What is the risk associated with compression of the brachial plexus in the lateral position?

The risk associated with compression of the brachial plexus in the lateral position is primarily the development of neuropathy. The brachial plexus is a network of nerves that originates from the spinal cord in the neck and extends to the arm. When the arm is positioned improperly or compressed during surgery in the lateral position, it can lead to excessive pressure on these nerves.

Neuropathy can occur when the normal blood flow to the nerves is compromised or when the nerve is physically compressed by surrounding structures or body weight. Symptoms may include pain, weakness, tingling, or numbness in the affected arm. This can significantly impact the patient’s recovery and functional use of the arm postoperatively.

Understanding this risk underscores the importance of proper positioning and padding techniques to protect the brachial plexus. Awareness of neuropathy as a potential complication can help surgical teams be vigilant in monitoring the position of the patient and making adjustments as necessary to prevent nerve injury.
