I work in ICU and we have numerous patients on GTN infusions, frequently on very high doses. We notice that sometimes once the GTN has been commenced the patients oxygenation drops, senior staff refer to this as "shunting". Can anyone explain what they mean by this?

I am new to a unit and have been told that I need to take a patient on CVVHD. I get some of the theory behind it but I'm still very confused. Can someone explain for me the role of the dialysate, replacement fluid and their path in the filtration system as it goes through the machine. So where does the fluid first go and where does it end up from each separate bag, e.g. ? to the patient or does it drain into another bag???

i work in icu... and i assisted with my first intubation today.. we initially gave some fentanyl, then propofol to sedate the patient, the we used suxamathonium as the paralyzing agent.... the patient was only a very small lady so that pretty much did the trick.... that is what we use most often in our unit..

I work in a adult CTICU and we generally get patients who will come back intubated post-op CABG, AVR, MVR , thoracotomy, correction of congenital defects etc.. depending on how stable the patient is they might come back with lots of inotropic support, IABP etc. As standard they will have some maintenance fluid, analgesia IV (morphine/fentanyl) and GTN... and chest drains. Our patients will always come back with an aterial line, cvc and pacing wires. But then again what the patient has depends on what they've had done and how unwell they are.
