Green urine from propofol

Abstract

"A 65-year-old female, with past medical history of hypertension and chronic hypoxemic respiratory failure due to chronic obstructive pulmonary disease (COPD), was admitted after endoscopic resection of colonic polyps and a large rectal mass. For this procedure, general anesthesia with intravenous Propofol was utilized. Due to technical difficulty of the procedure, the total anesthesia time was 7 hours and 48 minutes with a total use of 2,951.06 mg of Propofol. On post-procedure day #1, the patient's urine was noted to be green (Figure 1). The patient denied dysuria, frequency, urgency, and foul smell. Additionally, liver function tests, renal function tests, complete blood count, and urinalysis were all within normal limits."
