Cannulation is a funny old thing. As a medical student approaching the end of training, it was always one of those things you wanted to get good at before you were let loose on the wards. You’d ‘have a go’ in order to get your skill up, provided of course you could see and feel a vein from the end of the bed, otherwise you were destined for failure. Then, on becoming a fully-fledged house officer, you would pride yourself on your ‘tricky cannulations’, those ones that needed multiple attempts from other doctors, the ones that ‘needed the anaesthetist last time’. You’d compare scores with your junior colleagues, hoping you could be successful where they had not, hoping they wouldn’t be successful where you weren’t. You’d cannulate the most awkward of veins, finding a last, untapped vein in the most awkward of places – the elbow, the foot, the leg. And then, as your training progressed, you’d become further and further removed from this skill which you were once able to take so much pride in. It became a job for the junior members of the team, if not the medical students.
Approaching the end of my current A&E job, I find that there is going to be less and less of a requirement for me to cannulate, or take bloods (I’m moving on to paediatrics – where it is almost a given that you will fail and the put-upon Reg will come and do the honours – then GP, then psychiatry, neither of which have much call for these skills), which I’m finding a bit odd. It’s like preparing to say goodbye to an old friend (contrasted, for instance, with saying goodbye to night shifts). There’s a great piece of writing in the Oxford Handbook of Medicine that encourages doctors to rejoice in the calm few moments afforded when taking bloods, those precious few moments of peace when the doctor can be alone with his or her own thoughts.
I can say with all honesty that I will miss cannulation and venepuncture; it can give not only a few moments of peace in an otherwise busy shift, but also a tremendous sense of satisfaction, of achievement.
‘Well done,’ I always say, as I finish and remove the tourniquet. The patient may have been scared stiff, or stoical, or anything in-between, but I always say it. It’s just not always the patient I’m saying it to.
