These Guidelines are made available as general information only and do not constitute medical advice. These Guidelines are intended to assist qualified healthcare professionals make informed treatment decisions about the care of individuals with Friedreich ataxia. They are not intended as a sole source of guidance in managing issues related to Friedreich ataxia.

5. Surgical and anesthetic considerations in Friedreich ataxia
Individuals with Friedreich ataxia are considered at high risk of complications related to surgery and anesthesia due to comorbidities such as cardiomyopathy, scoliosis, diabetes and compromised lung function (1, 2). Cardiomyopathy is present in most individuals with Friedreich ataxia and left ventricular outflow obstructions should be avoided (1). The presence of scoliosis presents challenges for the use of central neuraxial blockade (1). In addition, concerns have been reported about the use of general anesthesia (3); however, the successful implementation of techniques such as combined spinal epidural anesthesia and total intravenous anesthesia have been reported (2, 4).
This chapter describes the particular surgical and anesthetic considerations relevant to individuals with Friedreich ataxia, focusing on monitoring cardiac function peri-operatively and managing the needs of individuals, both during and after surgery. In writing best practice statements and recommendations, the authors were tasked with answering the following questions:
For individuals with Friedreich ataxia, what management strategies could be implemented to monitor cardiac function peri-operatively? (see 5.1)
For individuals with Friedreich ataxia, what management strategies could be implemented regarding fluid and operative management? (see 5.2, 5.3, 5.4)
Lay summary of clinical recommendations/best practice statements for surgical and anesthetic considerations in Friedreich ataxia
Why these recommendations/best practice statements?
Friedreich ataxia is often associated with heart problems, scoliosis, diabetes and reduced lung function. This means individuals with Friedreich ataxia may be at greater risk of complications while undergoing surgery than other people.
Particular types of anesthetics and careful monitoring of heart function and fluids may be needed when an individual with Friedreich ataxia has surgery. In addition, surgery and the reduction in activity after surgery may mean a person with Friedreich ataxia will quickly lose physical condition while they recover from the surgery.
What does this mean for you as a person living with Friedreich ataxia or caring for someone living with Friedreich ataxia?
If you are considering surgery it might be important for you to speak with your healthcare professional about Friedreich ataxia and surgery and what it means for you.
We suggest that individuals with Friedreich ataxia considering surgery should be seen by a cardiologist before surgery. In addition, monitoring of heart function should occur during surgery, particularly if there is significant loss of blood or extra fluid is required. Ideally surgery should be done in a center with cardiac intensive care facilities. It is best if mobilization (getting out of bed) commences as soon as possible after surgery.
Health providers may consider a range of anesthetic options for you, including spinal nerve blocks or anesthetics given intravenously.
Who are these recommendations/best practice statements specifically for?
These recommendations and best practice statements are for all individuals with Friedreich ataxia who may be considering or are undergoing surgery.
