38
Q

Muscular dystrophy’s muscle tissue eventually replaced by?

A

Fat and connective tissue; pseudo hypertrophy

39
Q

Pseudohypertrophic (enlarging) of what 2 things?

A

Tongue and calf muscles

40
Q

Can you use sux for muscular dystrophy?

A

NO bc risk of rhabdomyolysis, hyperkalemia, and/or cardiac arrest

41
Q

What has an increased incidence with muscular dystrophy?

A

MH so have dantrolene available

42
Q

7 inherited myopathies:

A
  1. Nemaline rod myopathy
  2. Myotonia congenital
  3. Paramyotonia congential
  4. Periodic paralysis
  5. Central core disease
  6. Multi core myopathy
  7. Centronuclear myopathy
43
Q

Myopathies sux and NMDR effects?

A

Unpredictable

44
Q

Group of disorders of skeletal muscle energy metabolism; defects result in abnormal fatigability with sustained exercise, skeletal muscle pain, and progressive weakness

A

Mitochondrial myopathies (kearns-sayre syndrome)

45
Q

Mitochondrial myopathies (kearns-sayre syndrome) and GA? (3)

A
  1. Drug induced myocardial depression
  2. Develop cardiac conduction defects
  3. Hypoventilation during early post op
46
Q

Alcoholic myopathy/ floppy infant syndrome effect with managing anesthesia? (3)

A
  1. NDMR increased sensitivity and sux can cause hyperkalemia
  2. Infants risk MH
  3. Ketamine does not cause significant respiratory
47
Q

What do you think of when you see myopathies?

A

Muscle relaxants and K+

48
Q

Most common disease affecting NMJ; decrease in functional ACh receptors at NMJ resulting from their destruction or inactivation by circulating antibodies

A

Myasthenia gravis

49
Q

MG and eye problem?

A

Deviation and dropping eyelid

50
Q

Limited to involvement of extraocular muscles (10% pts)

51
Q

Slowly progressive, mild form of skeletal muscle weakness that spares muscles of respiration (respond to anti cholinesterase drugs and corticosteroids)

A

Type 2a MG

52
Q

More rapidly progressive and more severe form of skeletal muscle weakness (respond to drug therapy is not as good, respiration muscles may be involved)

A

Type 2b MG

53
Q

Acute onset and rapid deterioration of skeletal muscle strength within 6mths (high mortality rate)

54
Q

Severe form of skeletal muscle weakness that results from progression of type 1 or 2

55
Q

Chest X-ray and ct scan to evaluate their need to remove thymus and any cancerous tissue that may be present and how often is this seen in MG pts?

A

Thymomas; 10%

56
Q

If surgery is performed to remove thymoma, does it lead to remission of MG?

57
Q

MG and intubation?

A

Can be accomplished without NMB bc of intrinsic muscle weakness and relaxant effect of volatile anesthetics on skeletal muscle

58
Q

Skeletal muscle weakness usually with small cell carcinoma of lung; this deficiency restricts Ca++ entry when terminal is depolarized

Myasthenic syndrome

59
Q

What other syndrome resembles MG?

A

Eaton-lambert syndrome

60
Q

Myasthenic syndrome and muscle relaxants

Sensitive to both NDMR and DMR; anticholintesterase drugs may be inadequate; so decrease doses of muscle relaxants

Anterior flexion of spine

A

Kyphoscholiosis

63
Q

65
Q

Pts will be on what drugs for rheumatoid arthritis?

A

NSAIDs and/or glucocorticoids

66
Q

What joints are affected with rheumatoid arthritis?

A

Every joint except thoracic and lumbosacral spine

67
Q

Rheumatoid arthritis and neck movement?

A

Atlantoaxial subluxation may be present; minimize movement of head and neck during DL to avoid further displacement of odontoid process and damage to brainstem or spinal cord

68
Q

Spinal column can be stiff and deformed and prevent appropriate cervical spine motion for endotracheal intubation; restrictive lung disease from costochondral rigidity and flexion

A

Ankylosing spondylitis

69
Q

Best approach for spinal and epidural anesthesia?

A

Para median

70
Q

What Genetic marker in people with inflammatory arthritis of spine and joints (not osteoarthritis) and is associated with presence of one of a group of diseases called what?

A

HLA-B27; seronegative spondyloarthropathies

71
Q

HLA-B27 genetic marker can be seen in what 3 diseases?

A
  1. Ankylosing spondylitis (AS)
  2. Psoriatic arthritis
  3. Reiter’s syndrome (reactive arthritis)
72
Q

2 forms of dwarfism?

A
  1. Proportionate

2. Disproportionate

73

A

Tracheomegaly

74
Q

Osteogenesis imperfecta has the potential for what?

A
