A 6-year-old patient underwent an outpatient tonsillectomy and adenoidectomy. The surgeon ordered 1, cc D5W, dispensed at a rate of cc every 8 hours, to maintain hydration levels.
A pharmacist calculated the infusion rate for the IV drip to be administered. He used a calculator and checked his calculations twice.
The nurse who started the infusion obtained a bag of D5W, which contains 1, cc of fluid, and administered the IV solution to the child.
Like other nurses in her unit, she relied on the accuracy of the pharmacist since he had a reputation for correctness. Therefore, she did not check his calculations even though her job duties include verifying dosages. Once the first 1, cc bag of D5W was empty, she hung a second bag to infuse.
The child began vomiting frequently, which is not unusual in the recovery for this surgery. The child was given medicine to ease the vomiting. Forty minutes later the child exhibited seizure-like activity, which is unusual in the recovery from this type of surgery.
This behavior increased over the course of the day, during which a third 1, cc bag of D5W was hung to dispense.
The pediatrician on call noticed the patient was experiencing hyponatremia and water intoxication due to the high IV infusion rate and lack of sodium chloride in the infused medicine.
