Clinical PracticeA 3-day-old Standardbred colt has strained to urinate, passing small amounts, for 24 hours and now has a progressively distended abdomen. Temperature is 100.6°F (38.1°C), heart rate 110 beats/min, and respiratory rate 48 breaths/min. Ballottement produces a fluid wave, and ultrasound shows a large volume of anechoic peritoneal fluid. Peritoneal fluid creatinine is 13.8 mg/dL (1220 µmol/L). Serum results are shown, and the ECG shows tall, peaked T waves with bradycardia. Surgical repair of a ruptured bladder is planned. Which of the following is the most appropriate first step?
