Congratulations on finishing the first one and welcome to the club. There are many more to come hehe
The worst ones are after hours during your surgery term, they can be up to 16-17 hours long with only a single break depending on how busy you are.
Things will get easier though as you become faster at cannulas, fluids, clinical reviews etc, knowing what to quickly look for. A few tips I can add:
1. make sure you take breaks to eat/rehydrate, you'll be slow and useless if you don't. I used to work something out with the other intern so that we would carry each others pagers and respond to the urgent calls so that each of us would have two 30 minute breaks during the shift
2. always be thorough reviewing a patient, even if it seems simple. You don't want to see a delirious patient and miss the ischaemic gut because you didn't do an abdo exam. One patient that I'll always remember is a elderly man reviewed by an intern (not me) with a productive cough, relatively low temperature (35.3) and blood pressure trending down, but a stable heart rate. They were overlooked as being septic because of their HR, but it wasn't noticed that they were on metoprolol 50 BD for AF. Especially in your first year, make sure you do a full examination, look at and make sure you understand all the medications, consider the patient's comorbidities etc AND document all of this
3. always ask for advice for anything more complicated than a cough in the first few months. It sounds excessive, but you don't want to be *that guy* who has a patient deteriorate or worse because they missed something (like the intern, again not me, who didn't do a trop on a patient with sudden onset "sharp" pain and missed the beginning of a NSTEMI). One of the things you'll learn the fastest is how little you actually know, and that there's a big jump between theory and practice. It isn't a reflection on you, it is a reflection on the huge amount of material you need to learn as a doctor. Also don't be scared about the reg's getting angry, they aren't annoyed by your ability, rather they are annoyed by the extra work (which is really the patient's fault). This is the one time in your career where you can ask a stupid question and not be judged, exploit it!
