What is involved when have a pre-op assessment?

what is involved when having a pre-op assessment for orthopaedic surgery and why allow 4 hrs?
you will possibly have xrays and blood test done . the doctor will tell you what thje operation is all almost . good luck
Don't worry in the region of it too much, I've just had a knees op at the Royal National Orthopaedic Hospital. Now, I did my pre-op over the phone (Q&A regarding allergies, etc), and had the nouns at my GP (RNOH is a long way from my house!). The examination consisted of both urine and blood test, and was sent to RNOH for me.
I had to stir in a day earlier the actual op, and at this time my blood was taken again, I was weigh, and the op explained to me (for about the hundredth time, I knew adjectives about it by then).
Before the op, you might want to request a pre-op sedative. They may not ask you if you want it. Take it. I be never asked and I wish I had it. Also, after the op, especially if you're resting, insist on wearing anti-embolism stockings. I be not given these after a knee op, and two days later be rushed into my local hospital with a Pulmonary Embolism (a blood clot that moves to the lungs), and am now on Warfarin. You don't want that, trust me, that be damn scary (esp. considering a friend of mine died of it in 2003).
All of the above, and the nurse will also take your temp, blood pressure and respiration. Check what you are allergic to, assessment your urine. Make sure all the paper work is done. Your consent form is signed and if basic prep the skin where the surgeon is going to cut. then put a funny hood and gown on you (sometimes leggings and pants also) then grant you your pre-medication. You should feel quite drowsy prior to the operation and rouse feeling that you have only just blinked your eyes and it will be all over.
with the doctor ,blood pressure ,chest checked ,weight to see how much the anaesthetist give you
Quite simple really ,nothing to worry in the order of
What is done depends on your health status and age and what procedure is anyone done.

For example, if you are older or have diabetes, illustrious cholesterol, you might get a chest x-ray and an electrocardiogram. (Both painless) They may also want some blood tests for things similar to anemia.

If you have respiratory problems you might get an arterial blood gas or a breathing question paper to evaluate your lung function.

These are just a couple of examples.

Generally, if you are healthy you don't requirement a lot tests, if any.

Mostly what will be involved is the surgeon or his/her assistant explaining the procedure, the risks and option. You'll sign paper work that says you agree to the surgery and have a handle on the risks.

Then you may have to visit folks from anesthesia or from financial counseling.

The purpose all of this takes so long is mostly because you're going to be sitting around waiting for your turn for respectively step in the process.

Good luck.
They need 2 check:-

Blood pressure.
Allergies. Drugs/food/equipment.
They may cover UR Family history, c if there's anything they need 2 B aware of.
It take time & U mayB left waiting 4 a while if specialists need 2 grasp involved.
it take so long for you to have your x-ray taken. they usually prioritize patients from the A & E so, you'll probably be there sittin for atleast an hour and next those blood results as well...
You will have labs drawn, a chest x-ray and perhaps an EKG. Those test do not take that long.....most of the time you will be waiting your turn. Source(s): Nurse
They just examine you with the outlook of giving you an operation !
All things are taken in to narrative,Respiration,Heart,Medication,Med… History,Weight,Physical and Mental Health.
its mostly to help the staff work out the strength of anaesthetic to use and how you will tolerate the operation also your predicted rate of recovery from the op,Nothing to verbs about and to whoever is involved all the best.Paramedic 35yrs and merciful with numerous ops from 1992.
Paperwork, Long wait, poor explanations.
in a nutshell, a pre-op evaluation is the method an internist assesses a patient's cardiac and pulmonary risk of having the procedure. after assessing the risk, the internist tries to way the risk of the procedure versus the benifit surrounded by order to give the lenient advice about whether they should enjoy the procedure.

the surgeon wants to know is this patient in good health enough to tolerate this procedure. is this patient going to hold a heart attack or respiratory arrest because of this procedure?

if the internist feels that the patient is at glorious risk for the procedure, then the surgeon better have a worthy reason to do the procedure, ie the procedure shouldn't be elective.

if the procedure is neither elective nor emergent, and the patient is at dignified risk, the internist can elect to further risk stratify the patient by asking the patient to put up with more tests such as stress test. if the long-suffering "fails" the stress test, then it can be assumed the forgiving is unsafe for surgery. in this instance the patient would predictable undergo a cardiac catherization to determine if there are any blockages contained by the heart that can be fixed before the surgery.

hope that helps...
drug's and test's and a medical check usually
Chest Xray
Lab work - PT/PTT/INR to make sure you won't bleed
Anesthesia will come sermon to you, check out your airway, confirm that you have no allergies, confirm your comorbidities, etc.
It all take a lot of time...But it is to make sure you take home it through with flying colors.
