things to remember after pt has partial or total thyroidectomy? | keep one arms distance and should really be alone for 24hrs |
Pre op care for thyroidectomy? | pt should be euthyroid before sx, antithyroid drugs, iodine prep for 10-14 days prior, achievement of good nutritional status and normal wt |
