Final answer:
Anesthetic considerations for ankylosing spondylitis encompass increased risks of difficult intubation, spinal cord injury, and postoperative respiratory issues, with the correct response being all of the above.
Step-by-step explanation:
The anesthetic considerations for a patient with ankylosing spondylitis include an increased risk of difficult intubation, an increased risk of spinal cord injury, and an increased risk of postoperative respiratory complications. Therefore, the correct answer to the question is 4) All of the above.
Patients with ankylosing spondylitis often have a limited neck movement and jaw opening, which can lead to difficulties in airway management and intubation. The stiff and possibly fused spine also can increase the risk of spinal cord injury during anesthesia, especially if spinal or epidural anesthetic techniques are used. Moreover, reduced chest wall and lung compliance can lead to postoperative respiratory complications such as atelectasis or pneumonia.
