Question

Complications of anaesthesia in sitting position neurosurgery.

Hint:

Careful monitoring and positioning are crucial when using the sitting position in neurosurgery to minimize risks such as air embolism and hypotension.

Answer 1

Step 1: Complications of Sitting Position in Neurosurgery:
1. Venous Air Embolism (VAE): One of the most serious complications, VAE can occur due to the sitting position, especially during craniotomies or spinal surgeries. It can lead to cardiovascular collapse if not managed promptly.
2. Postoperative Hypotension: The sitting position can cause a significant drop in blood pressure due to the pooling of blood in the lower extremities and reduced venous return.
3. Spinal Cord Injury: Improper positioning can lead to pressure on the spinal cord or nerve roots, causing neurological damage.
4. Complications from Inadequate Ventilation: The sitting position can restrict chest expansion, leading to breathing difficulties, especially in patients with pre-existing respiratory conditions.
