Quite a few NS threads lately, so I thought I would share a few things I've learned.
I'm a former phlebotomist/EMT/UAU and lab tech. I was originally hospital-trained, and have a tad over 100,000 veinpunctures performed. I've had 1 NS, in 20 years, and it was an uncapped syringe left in a room- not one I handled.
Body mechanics are a significant part of preventing self-inflicted sticks. I do not sit, when sticking, as the natural reaction, if bumped, is to move the hands up and forward- which will drive a needle neatly into one's hand.
When sticking, first and foremost, the needle goes nowhere but into the patient (or maybe the bed). That means that if the patient moves suddenly, they get jabbed; a bomb goes off in the parking lot, the patient gets jabbed; lights go out, the patient gets jabbed- maybe the mattress, as long as it isn't in the direction of your hand; a fire-nado-caine-alanche comes down and consumes your hosptital, yep, you guessed it.
What we are trying to mitigate is the startle-response. When adrenalized, our bodies experience a systemic contraction and some level of stabilization-response, such as extending/retracting the hands. What you want to train-in is a rigid locking of the sticking arm perpendicular to the torso. Along with this, applying firm, downward pressure with the sticking hand stabilizes your needle entry, and also connects you to the patient.
The untrained response, relating to that connection, when the patient moves or when we are startled, is to draw away from contact with the patient. The problem is that we have lost all foundation at that point. Our desire being to hold the needle in mid-air, so that no one-particularly the patient- is injured, results in a free-floating missle, ready to be driven into any on-coming surface. That surface is typically us, as either we retract our arms and hands to shield our core torso, or we hyper-extend to catch an anticipated fall.
Most of this is situational, but can be addressed by changing how we perceive a situation, rather than hard and fast rules or safety devices. Primarily: how may I best position myself so that I am not readily in-line with my needle? Secondly: your needle always faces your patient. Our gaze is normally a tandem effort, our eyes move in unison in the same direction. Manually, we have (generally) learned to move our hands together. Adapt your sticking so that your mechanics are more parallel, not intersecting. I.e., when sticking, your needle is always between your patient's body and the dominant side of yours, never pointing towards the non-dominant side.
If, for some odd-ball reason, you must move with an exposed sharp, hold it in the dominant hand, across the chest and pointing toward the non-dominant shoulder. Face your dominant side, and move with that side of the body leading. If bumped or startled, the sharp will be pressed parallell to the body, with the head ducking further towards the dominant shoulder, away from the needle.
Regarding gloves/no gloves, I will simply say that is a performance-bias issue. We do what we want to do until we are conclusively shown that it causes problems.
Just a mini-rant, that hopefully will help someone to evaluate their mechanics. I always find it interesting when the practical skills are said to be better suited to OJT, unnecessary, etc., when basic safety is such an issue in this profession.
