Risks with osteogenesis imperfecta include

A

fractures that can occur during patient positioning and NIBP cuff inflation

28
Q

For patients with marfan syndrome there is a risk for

A

spontaneous pneumothorax

29
Q

For patients with Marfan syndrome, _________ increases the risk of cardiovascular complications

A

pregnancy

30
Q

When we think of Marfan syndrome we should think of

A

aortic insufficiency and AAA

31
Q

When we think of Ehlers-Danlos syndrome we should think of

A

spontaneous bleeding into joints and AAA

32
Q

When we think of osteogenesis imperfecta we should think of

A

weak bones

33
Q

Is the risk of MH increased with osteogenesis imperfecta?

A

No

34
Q

A unique finding in patients with osteogenesis imperfecta is

36
Q

_________ is increased in >50% of patients with osteogenesis imperfecta

Serum thyroxine (increased BMR and VO2–> hyperthermia)

37
Q

Multiple sclerosis is a

A

demyelinating disease of the CNS

38
Q

Classic teaching with multiple sclerosis suggest that while _________ anesthesia is safe, __________ anesthesia may exacerbate symptoms.

A

epidural; spinal

39
Q

Select considerations for patients with MS include

A

bulbar muscle dysfunction (aspiration risk), chronic steroid therapy, and sensitivity to increased body temperature (risk of demyelination)

40
Q

Myotonic dystrophy is characterized by a

A

prolonged contracture after a voluntary contraction

41
Q

Factors that increase the risk of sustained muscular contractions for patients with myotonic dystrophy

A

42
Q

Scleroderma causes
