What is rheumatoid arthritis (slide 2-3)? | Pain & morning stiffness in mult joints, progressive joint deformity |
W/ rheumatoid arthritis, what are some airway issues to consider (2 of them) (slide 2-3)? | limited TMJ (temporomandibular joint) & narrow glottic opening: use smaller tube |
W/ rheumatoid arthritis, what is a cervical spine issue to consider (slide 2-3)? | atlantoaxial instability: Do NOT crank their heads back! |
W/ rheumatoid arthritis, what are some cardiac issues to consider (2 of them) (slide 2-3)? | pericarditis & tamponade: check cardiac concerns w/ echo |
W/ rheumatoid arthritis, what is an eye issue to consider (slide 2-3)? | Sjogren's syndrome (consider eye ointment) |
W/ rheumatoid arthritis, what is a GI issue to consider (slide 2-3)? | ulcers, especially secondary to NSAIDs & ASA (these pts have chronic NSAID & ASA use) |
W/ rheumatoid arthritis, what are some pulmonary issues or signs & symptoms to consider (5 of them) (slide 2-3)? | interstitial fibrosis, diffusion impairment, possible hypoxemia evidenced by cough, dyspnea, PFTs show restrictive pattern |
W/ rheumatoid arthritis, what is a renal issue to consider (slide 2-3)? | renal insufficiency secondary to NSAIDs (these pts have chronic NSAID & ASA use) |
What are the 3 drug classes that can be used to treat rheumatoid arthritis (slide 3-1)? | disease modifying drugs (methotrexate, remicade, enbrel), NSAIDs, and glucocorticoids |
What is a side effect of disease modifying drugs (slide 3-1)? | increased risk of infection |

What are 4 side effects of glucocorticoids? If pt is on high doses what should they be given intraop (slide 3-1)? | osteoporosis, cataracts, cushingoid symptoms, & hyperglycemia. If pt is on high doses they should be "stress dosed" w/ hydrocortisone (solu-cortef) 100 mg |

What is transient neurologic symptoms? What is the incidence, onset & duration (slide 3-2)? | pain in butt & legs; occurs more w/ spinal lidocaine. Incidence = 1 - 14%. Onset = 1 day. Duration = 2 - 5 days |
What is an issue with a femoral nerve block (slide 3-2)? | persistent quad weakness |
Tourniquets are used primarily to _____. Width should be ____. Max safe pressure should be ____ for the arm & ____ for the leg (slide 3-3) | Used to minimize blood loss. Width should be >50% diameter of the limb. Max safe pressure: 50 mmHg over max systolic for arm, 100 mmHg over max systolic for leg |
Risk of tourniquet is (slide 3-3) _____ | ischemic damage to underlying nerve & muscle |
4 s/s of tourniquet pain are (slide 3-3): | dull, aching, restlessness, & BP trends up |
What may occur after tourniquet deflation & how is it treated (slide 3-3)? | Transient metabolic acidosis & high CO2 levels. Increase minute ventilation. D/t vasodilation BP may also drop |
Ankle block consists of 5 discrete nerves around the ankle. Which ones are terminal branches of the sciatic nerve? Which ones are terminal branches of the femoral nerve (slide 4-1)? | terminal branches of sciatic nerve = posterior tibial (plantar surface), deep peroneal (interspace between 1st & 2nd toe), superficial peroneal (dorsum of foot), & sural (back of & plantar surface of foot) |
