Has anyone been using lidocaine infusions intra/postop in obese pts having abdominal surgery? Used it for the first time Friday on young guy (30's) for open gastric sleeve with a BMI 69. Normally I just do ketamine (0.25 mg/kg bolus then 0.1 mg q 1 hr) to limit narc requirements but new attending wanted to give it a go and I had read a little bit about it but seems like the research isn't overly convincing right now so was wondering if anyone else has tried.
I will say he didn't cough during emergence tho!
