Step 1. Calculate the 24 hr morphine dose: 3 mg x 24 = 72 mg IV morphine/24 hrs; Step 2. Convert IV to oral morphine: at a ratio of 1 mg IV = 3 mg oral; thus 72 mg IV = 216 mg po/24 hours; Step 3. Convert the oral morphine dose to Duragesic - there are two methods: METHOD 1. Look in the PDR, find the morphine conversion table, it says that 135-224 mg of morphine = 50 mcg patch. Note, this range of morphine is very broad; 50% of patients will be under-dosed when this conversion table is used. METHOD 2. Use a ratio of MS:fentanyl of 100:1; 216mg/100/24hrs = 90 mcg/hr, can rounded to 75 mcg or 100 mcg patch.
The bridge is an engineering feat on its own and there is an informative foot path up to the bridge and a pedestrian walkway across it. You can get great photos of the bridge from Hoover Dam and of Hoover Dam from the bridge. Standing over that much air was a little unnerving for me, but still pretty neat.
