A Weekend with Penny and an Update on Isaak

When last we left our intrepid band of preemies, Penny had been discharged but Isaak was having complications and was getting all kinds of workups for infections. I'm happy to report that (as daddy suspected) he appears to have just been very cold. Nothing has grown in any of the cultures, including the lumbar puncture. They will continue to watch the cultures, but so far nada. Now, it's not good that he gets cold so easily and we have no idea why he is having so much trouble regulating his temperature, other than because he's a preemie. It's concerning, but all we can do is keep him well wrapped and check his temp more frequently to avoid a recurrence and hope he grows out of it as he gets bigger.

Today was exciting as he's hit 10ml per hour via g-tube feeds. He has started pooping, but no signs of "dumping" yet. What might be the difference between pooping and dumping, one might logically ask? "Dumping" in this context means that very little of the oral/g-tube intake is being processed. It's essentially shooting straight through the GI tract. What's worse, it may actually pull additional fluid out. So maybe you had an intake of 10ml per hour, but are outputting 15ml per hour. That is not a good scenario and is one of the more common issues with short-gut patients. The challenge is finding that upper limit.

10ml was the main target so that he would be getting the majority of his nutrition and fluids enterally rather than via TPN. Right now, due to reduced fluid intake, he's getting over 70% of his feeds as breast milk. That is good for Isaak and very very good for his liver. His bilirubin counts have gradually begun to drop as he's getting less TPN. As he gains weight, the TPN percentage will go up a bit as his digestive system might not be able to tolerate significant increases in volume just yet. If we can keep him over 50% oral/g-tube intake, he'll be in a good place.

Little guy is still having problems with edema (thus the reduced fluid intake) and started a second 3-day course of Lasix yesterday morning. He was looking quite good in the evening and appears to be excreting a bit more so there is hope he will begin regulating his own fluids shortly. It's not uncommon for preemies to have issues with edema, nor is it uncommon for anyone that has had abdominal/GI surgery - so Isaak is experiencing the old double whammy.

Hopefully, control of his fluid levels will also help his other remaining issue - oxygen addiction - he loves the wall juice. What's weird is how little he is actually getting. They have him on a flow rate of 0.05 lpm - an absurdly low number - but if they try to drop to 0.025 lpm, he starts desatting. It really is crazy. Part of this may be an issue with hematocrit. His numbers are dropping again and they are doing a blood count, including reticulocytes, to see if he is making a reasonable number of blood cells. If he is, the question then becomes: What is eating the mature cells? Why isn't he having a net gain? It may (hopefully is) just be something he has to mature past and only time will take care of that.

So on to Miss Penelope!

How is it having a baby in the house again? FANTASTIC (and exhausting). I don't think Bekka and I will be used to just picking her up and squeezing her (gently) anytime we want for weeks yet. After watching her grow from that tiny little newborn to her current petite, but relatively huge size, and only seeing her for a few hours a day, it's wonderful to have her there all the time. We have discovered that if we want to get any sleep at night, we have to feed her a big bottle of mom's milk fortified with extra calories from formula. Otherwise, she wants to feed about every 2 hours and that is tough on mom and dad. Nursing is hard work for babies, and while she is good at it, she just can't get as much food that way before she's tuckered out as she can with a bottle. With time, she'll get better and better at nursing.

That's all for now.
