There's not much to actually WORKING in PACU other than your ABC's and surgical sites but you DO need to have a good knowledge base for when things don't go quite as planned. Know how to manage an airway including ambuing, oral and nasal airways, endotracheal tube management, and Laryngeal Mask Airway management. Read up on your narcotics (Fentanyl, Dilaudid, Morphine, Sufenta, and Remifentanyl), anti-emetics (Zofran, Phenergan, and Inapsine.). Be familiar with versed, ephedrine, phenylephrine, albumibn, hespan, propofol, sevoflurane, desflureane, isoflurane, neostigmine, and robinul.
Those are the most common medications you'll encounter in the PACU. If you have a high acuity PACU that admits ICU patients also you should be familiar with levophed, epi, cardene, nipride, chest tubes, trachs, etc.
Be familiar with reversal agents such as Narcan, Romazicon, and protamine. One thing to note....in PACU we general don't give entire "rescue" doses of reversal such as 0.4mg of Narcan. We generally dilute it down and titrate to effect (i.e. the patient is now spontaneously breathing again). I gave .05mg of Narcan about two days ago. I can honestly say I have never given a 0.4mg dose in PACU.
Just a few things to consider!
