Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

1.7K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Pneumothorax-II

579
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Trachea

3.4K
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

Flail Chest-II

350
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Flail Chest-I

372
Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Spinal Nerves: Plexus II01:21

Spinal Nerves: Plexus II

1.2K
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Summary

A brachial plexus block caused temporary left hemidiaphragm paralysis in a patient undergoing surgery. This led to tracheal deviation, a rare complication of phrenic nerve palsy.

Area of Science:

  • Anesthesiology
  • Thoracic Medicine
  • Neurosurgery

Background:

  • Brachial plexus blocks are common for upper extremity surgery analgesia.
  • Phrenic nerve palsy is a known complication, but its radiographic presentation can vary.
  • This case explores a specific, unusual radiographic finding secondary to phrenic nerve palsy.

Observation:

  • A patient undergoing left brachial plexus block developed desaturation and reduced left-sided air entry post-extubation.
  • Chest X-ray revealed left hemidiaphragm elevation and contralateral tracheal deviation.
  • No pneumothorax was observed, ruling out common causes of such findings.

Findings:

  • The radiographic findings were consistent with left phrenic nerve palsy.
  • This palsy resulted from the supraclavicular brachial plexus block.
  • The contralateral tracheal deviation is a novel observation in this context.

Implications:

  • Highlights the importance of recognizing phrenic nerve palsy after brachial plexus blocks.
  • Suggests that contralateral tracheal deviation can be a sign of ipsilateral diaphragmatic paralysis.
  • Emphasizes the need for careful radiographic interpretation in patients with respiratory compromise post-nerve block.
