[Anesthesia for emergency surgery in 2 extremely low birth weight infants with ileus]

Two extremely-low-birth-weight infants, weighing each 684 and 975 g at birth, underwent emergency surgery because of ileus. Our previous experience with an extremely low birth weight infant, whose hemodynamic control during the surgery had been difficult without administering extra preoperative fluid and transfusion, made us administer enough fluid and transfusion during operation although their urine output was more than 2 ml.kg-1.hr-1. We gave intravenous volume to the present 2 cases before the operations despite the level of preoperative urine output and made their hemodynamic situation more stable during surgeries. We conclude it is very important to administer some amounts of intravenous volume (approximately 8-12 ml.kg-1.hr-1) in extremely low birth weight infants for emergency surgery with ileus regardless of their preoperative urine output.
