Carpal tunnel syndrome: Nursing

Carpal tunnel syndrome is a condition in which the median nerve is compressed inside the carpal tunnel of the wrist, causing pain and tingling in the hand.

Let’s start with a bit of anatomy and physiology. The carpal tunnel is a rigid canal in the wrist, created by a sheet of fibrous tissue forming its roof, and the carpal bones forming the floor.

The tendons of forearm muscles run through this canal, as well as the median nerve. The median nerve supplies motor, sensory, and autonomic innervations to the thumb, index, and middle fingers, in addition to the palmar aspect of the ring finger.

Alright, now the cause of carpal tunnel syndrome is not clear, but there are a number of risk factors, including jobs and activities that involve repetitive movement of the wrist, such as musicians, carpenters, excessive cell phone use, and certain sports, such as golf, tennis, or racquetball.

Median nerve compression is generally more common in clients who are assigned females at birth since they tend to have a smaller carpal tunnel.

Hormonal imbalance, which can occur during the premenstrual period, pregnancy, and menopause, can also increase the risk for carpal tunnel syndrome.

Other risk factors include conditions that may cause swelling inside the carpal tunnel, including diabetes mellitus, peripheral vascular disease and rheumatoid arthritis, as well as acromegaly, which is when excessive growth hormone causes excessive growth in the adult bones and tissues, which can narrow the carpal tunnel.

Regardless of what triggers carpal tunnel syndrome, pathology-wise, there’s increased pressure inside the carpal tunnel, which results in obstruction of venous outflow.

This leads to fluid moving from the blood vessels and into the carpal tunnel, which increases the pressure even more, ultimately causing median nerve compression.In terms of clinical manifestations, clients with carpal tunnel syndrome typically present with pain and paresthesia in the thumb, index, and middle fingers, and the radial half of the ring finger, as well as clumsiness in fine hand movements.

These symptoms are typically worse at night and they may even awaken the client from sleep, and they are often relieved by shaking out their hands.

The diagnosis of carpal tunnel syndrome starts with the client's history and physical assessment, which includes two tests.

The first is the Phalen maneuver, where both wrists are flexed to 90 degrees, and maintained in that position for more than one minute.

When the symptoms of carpal tunnel syndrome are reproduced, the test is considered positive. The second is the Tinel test, which is performed by repeatedly percussing firmly over the carpal tunnel, and if carpal tunnel symptoms appear, that’s a positive test.

To confirm the diagnosis of carpal tunnel syndrome, electrophysiological testing of the median nerve is used to assess the degree of nerve damage.Now, the treatment of carpal tunnel syndrome is typically non-surgical.

Initially, a wrist splint can be used during the day, night, or both. This helps immobilize the wrist in a neutral position and prevent excess flexion or extension that can worsen symptoms.

If this does not work, corticosteroids can be injected into the carpal tunnel to reduce inflammation.On the other hand, clients with significant impairment or symptoms lasting for more than six months may require surgical decompression of the median nerve.

This involves making a longitudinal incision through the roof of the carpal tunnel to decrease pressure and can be done either endoscopically, or through open release.

Alright, let’s move on to the nursing care you’ll provide to a client diagnosed with carpal tunnel syndrome. Nursing goals are aimed at relieving the nerve compression and providing supportive care.

Begin by assessing your client’s level of pain, including its location, onset, frequency, and duration, as well any associated symptoms like numbness and tingling.

Administer the prescribed analgesics or anti-inflammatory medications as ordered and immobilize the affected hand and wrist with a splint.

Now, if you’re caring for a client after carpal tunnel release surgery, assess the affected hand’s neurovascular status, and encourage your client to keep the affected hand and arm elevated above the heart and to move their fingers frequently.

Report to the healthcare provider if you notice any reduced or absent sensations, as well as increased numbness or tingling.

Alright, now let’s talk about general client and family teaching. First, explain how inflammation and swelling can cause pressure on the median nerve, causing pain, numbness, and tingling.

Then, demonstrate how to apply the splint and ensure they know when they should wear the splint and for how long. Also make sure to discuss some strategies they can use to help decrease symptoms.

These include to avoid overusing the affected hand, and to try and use the unaffected hand more often; as well as keeping their affected wrist in a neutral, straight position as often as possible; avoiding holding their wrists in a downward bent position for an extended period of time, and taking frequent breaks between activities to allow their wrist and hand to rest.

If your client is recovering from surgery, let them know their wrist and hands could be swollen and stiff initially. Instruct them about their prescribed analgesics for pain, and be sure that a referral for physical therapy has been placed for rehabilitation hand and wrist exercises.

Advise them that certain hand movements and lifting heavy objects should be avoided for at least 4 to 6 weeks. Lastly, advise your client to notify their healthcare provider if they experience bleeding or increased redness, swelling, drainage, warmth, or pain around their surgical site; or if they develop a fever or chills.

Stress the importance of seeking emergency medical treatment if numbness or tingling gets worse, if their fingertips become cold, pale or bluish in color, or if they can’t move their fingers.

Lastly, remind them to keep all their follow-up appointments for ongoing monitoring and care.Alright, as a quick recap… Carpal tunnel syndrome is a condition in which the median nerve is compressed inside the carpal tunnel of the wrist, which causes pain and tingling in the hand.

Risk factors include jobs and activities that involve repetitive movement of the wrist, such as musicians, carpenters, certain sports, such as golf, tennis, or racquetball.

The diagnosis of carpal tunnel syndrome starts with the client's history and physical assessment, which includes the Phalen maneuver and Tinel test.

Initial treatment initially can be splinting to help immobilize the wrist in a neutral position. Corticosteroids and surgical decompression of the median nerve may also be required depending on the extent of the nerve damage.

Nursing goals are aimed at relieving the nerve compression and providing supportive care. Client and family teaching is focused on lifestyle modifications, postoperative care at home, and when to seek medical attention.
