Symptom narrative

DTaP, HiB and varicella vaccines administered at approx. 8:50a.m. Symptoms of fussiness and sleepiness started approx. 10:45 a.m. Background: Parents and grandparent all had a GI illness in the 8 days prior to this incident. Symptoms for them lasted approx. 12 hours. Fell asleep with mom holding him; could not get comfortable, grunting and groaning intermittently while sleeping. Woke up, temperature of 103.2 tympanic measured by parent. He then vomited a large amount. Parents put him in the bathtub then in the shower with mom. He became pale and started to shake. He would not interact with parent, would not look at mom when she would talk to him. Temp after coming out of the shower was initially measured at 105 tympanic then down to 103 within a few more minutes. Mom is a pediatric RN and reported that he was hypotonic. Parent called PCP RN triage and was instructed to take patient to the ER. In the car on the way to the ER he perked up a little bit per mom. Rectal temp in ER initially 100.2 then up to 103.2. Mom reports improvement in symptoms shortly after arriving to ER and during triage. He was appropriately upset during the triage process as VS obtained. He was given ibuprofen and Tylenol for symptoms; he kept those medications down and did not have any further emesis. Fever reduced to normal temperature. Fever returned after 12 hours, continued with intermittent fever for a total of approximately 24 hours. He displayed signs of hunger at this time, no further vomiting. Symptoms improved and returned to normal and he remained afebrile. No other symptoms developed.
