Which nerve is spared in supraclavicular block?

brachial plexus
The supraclavicular block, first described by Kulenkampf, provides a consistent homogenous blockade of the entire upper extremity without preferentially sparing the cephalad (musculocutaneous) or caudad (ulnar) nerves of the brachial plexus.

What is a supraclavicular nerve block?

The supraclavicular block is a regional anesthetic technique used as an alternative or adjunct to general anesthesia or used for postoperative pain control for upper extremity surgeries (mid-humerus through the hand).

What is phrenic nerve block?

Phrenic nerve block and hemi-diaphragmatic paralysis are common complications of brachial plexus blocks above the clavicle. The phrenic nerve originates from the ventral ramus of the fourth cervical nerve with contributions from the third and fifth cervical nerves, but the origin of the phrenic nerve is variable.

What is an Interscalene nerve block?

An Interscalene block is a form of regional anesthesia used in conjunction with general anesthesia for surgeries of the shoulder and upper arm. Simply stated, an Interscalene block will numb your shoulder and arm before surgery so that your brain will not receive any pain signals during and immediately after surgery.

What does supraclavicular block coverage?

The supraclavicular block is used for surgeries or postoperative pain control for the upper extremities. It is best for areas below the mid-humerus level. Above the mid-humerus, the shoulder area, an interscalene block would provide better coverage.

How long does a supraclavicular block last?

The duration of the effects of a supraclavicular nerve block depends on the type of anesthetic agent used. During surgery, mepivacaine provides fast-acting anesthesia, which sets in within five minutes and lasts up to three hours.

What is the difference between Interscalene and supraclavicular block?

The increased distance between the supraclavicular injection site and the phrenic nerve compared with the interscalene approach results in a reduced incidence of hemidiaphragmatic paresis. The shoulder joint is mainly innervated by the suprascapular and axillary nerves originating from the brachial plexus.

What irritates the phrenic nerve?

Phrenic nerve irritation If your phrenic nerve becomes irritated or damaged, you may lose the ability to take automatic breaths. The condition can be caused by a spinal cord injury, physical trauma, or surgical complications. With phrenic nerve irritation, you might also experience: hiccupping.

Can a damaged phrenic nerve heal?

Unless the phrenic nerve is injured on both sides, making the patient unable to breathe on his or her own, this is often an elective treatment situation. In some cases, the damaged nerve may heal on its own, but patients need to understand this isn’t an unlimited window.

What are the risks of a nerve block?

Risks of nerve blocks A nerve block can lead to bleeding and infection where the shot was given, the medicine may spill into other areas unexpectedly, and healthcare providers may hit the wrong nerve during surgery. Compared with many procedures, however, nerve blocks appear to be quite safe.
