Dr. Bohin certainly has more current neonatal experience than Dr. Evans.
Dr. Evans claims it wasn't the bleed at all, but an air embolus as well, iirc.
It depends, there's multiple possibilities. Sometimes people
think they have aspirated and gotten nothing or a small amount, but the tube adhered to the stomach wall, preventing aspiration, another possibility is mis-estimation of the volume vomited - which happens
constantly. Nurses here also chart emesis and they can do it as occurrence with small, medium, large or try and estimate volume. The volume estimates are almost always way off - liquid is incredibly hard to estimate when it is not contained in a vessel. I don't know the exact amount of time it would take, but it can be reasonably rapidly.
Projectile vomiting has less to do with the volume, more involves the musculature of the infant involved. We get projectile vomiting from time to time, with and without pyloric stenosis (the typical cause of projectile vomiting). It's unusual for babies to have a strong enough pylorus and esophageal sphincter to have enough tone to be able to projectile vomit, no matter the volume. But sometimes babies like to surprise us.
Reversible Adsorption of Soluble Hexameric Insulin onto the Surface of Insulin Crystals Cocrystallized with Protamine: An Electrostatic Interaction - Pharmaceutical Research to be able to reverse the adsorption, a fair amount needs to be done.
Yes, if the bag wasn't changed, there could be up to 25 ml if they were using a standard infusion set. Usually a set would be changed in these circumstances to not continue to give the lower amount of glucose, but it is definitely possible that could have happened.
Edited to add: insulin is
always mixed with glucose for neonates when it is administered, usually D5. We only administer insulin to babies as drips, not as individual doses.
