Q

What recovery room complications might you expect to manage in a patient who has undergone a carotid endarterectomy and why might these occur? How would you manage them?

[15B11] Describe the complications that can occur post carotid endarterectomy and how these may present in the post anaesthesia care unit (PACU).

What monitoring do you think is necessary for carotid artery surgery and why? Do the surgical and anaesthetic techniques make a difference?

What are the indications for a thoracoscopic sympathectomy, and what would be your anaesthetic and pain management plans?

SS_VS 1.4

A

The Society of Thoracic Surgeons Task Force reviewed the current literature and reached a consensus that

*primary hyperhidrosis of the palms, plantars, axillae, or face is best treated with endoscopic thoracic sympathectomy

Q

VASCULAR – Policy for endovascular stroke intervention
[18A05] You are developing an anaesthetic department policy for acute endovascular stroke intervention.
Outline the issues to be considered in your policy.

A

(41.8%) This question had a low pass rate. Successful candidates demonstrated a structured approach and mentioned communication lines between anaesthesia and other multidisciplinary teams. They recognised the time sensitive nature of treatment and prioritised tasks.

  1. RAPID ID of potential pts
    - rapid ED –> stroke call + MDT (neuro/IR/ICU/anaes)
  2. Prev 2nd BI
