Hi all! My almost 4yo ds was diagnosed in October, he has a Medtronic 640G pump with Enlite sensor, although the latter we have had only for a couple of weeks. The first couple of weeks after we came back from the hospital his BG was never above 180, then he got a cold and the rollercoaster started... BG up to 400! The first day this happened he didn't have a sensor yet, so it took us completely by surprise. He also had keton bodies in his urine! And that's when we realised that we were never told what to do in that case. It turned out that he was fine (finally his BG started dropping, and a few hours later the ketons were gone), but what a scare that was! His HA1c thing was 11.7 when we got to the hospital, but he didn't have DKA. On his last checkup it was 7.2. How low can it get? Wr have the SmartGuard function active, and since then we've noticed that the pump stops the basal insulin a few times per day. Then when I adjust something so that he gets less insulin and therefore doesn't drop that much, he has very high values the next day. Is it reasonable to expect basal interruptions often? Or do I have to try to do more finetuning? The hospital that is advising us supposedly doesn't have many pump+sensor+smartguard patients, so they said we should just experiment with the sensor+smartguard settings to find what suits us best. How do I know when the settings are right? We've had days when he goes up after eating and then stays up for hours, even after a correction bolus. In such a case he needs two or three correction boluses plus an increased basal rate for a few hours before dropping. There are other days when he hardly goes up after earing, amd then drops back down, then the pump stops again. Sometimes the pump stops for two bours, is active for half an bour, then stops again. Sometimes the pump stops only for half an hour on a given day, and his BG is within 60-180 for the whole day, sometimes one day is a mixture of all the above. How normal is this? Should we expect more consistent behaviour, a better setup of basal and bolus? Or is this to be expected? The doctors at the hospital said that people who are not in the honeymoon period anymore have a 50%basal and 50% bolus per day. He has about 75% bolus at the moment. He weighs 16kg and needs about 10 insulin units per day (Humalog). Is the honeymoon over? How do things change when honeymoon is over? Thanks for any comments you can offer! Sandra.
