T-Line Tensymeter Instead of Arterial Lines
I remember seeing this product at an anesthesiology meeting last year and thinking how great it would be for bariatric surgery (gastric bypass operations on the morbidly obese). It's an external device which, when strapped to the wrist and calibrated, can give a very accurate blood pressure reading. Depending on their upper arm morphology, a non-invasive blood pressure cuff may not work reliably in morbidly obese patients if the upper arm is cone-shaped. I used to start arterial lines on these patients, but this device, would be an alternative.
As almost all gastric bypass operations I give anesthesia for are done laparoscopically, this is less and less of an issue for me personally.
