Study Notes
Venepuncture and the Median Cubital Vein
- The median cubital vein is a primary site for venepuncture due to its superficial location in the cubital fossa.
- Accessibility of this vein simplifies blood collection procedures.
Blood Pressure Assessment
- A stethoscope is placed over the cubital fossa during manual blood pressure assessments.
- Auscultation of the brachial artery is performed to detect Korotkoff sounds, crucial for determining blood pressure.
Cubital Tunnel Syndrome
- Cubital tunnel syndrome is an ulnar neuropathy occurring near the cubital fossa, affecting the ulnar nerve.
- The ulnar nerve is positioned posteriorly to the medial epicondyle of the humerus, within the cubital tunnel.
- Nerve compression can be acute or chronic, leading to symptoms.
Symptoms of Cubital Tunnel Syndrome
- Patients typically experience sensory paraesthesia in the ulnar distribution: the medial hand and the medial one and a half digits.
- Motor symptoms may include clumsiness in performing intrinsic hand movements.
Treatment Options
- Treatment approaches include conservative methods like patient education and the use of elbow splints.
- Surgical decompression can be an option for cases that do not respond to conservative management.
