Abstract
Vital signs were as follows: respiratory rate, 16 breaths per minute; 97% oxygen saturation on 2-L nasal cannula; heart rate, 83 beats per minute; blood pressure, 114/69 mm Hg; ETCO2, 38 mm Hg; and CIWA score, 2 (tremors, 0; paroxysmal sweats, 1; anxiousness, 0; agitation, 0; tactile disturbance, 0; auditory disturbance, 0; visual disturbance, 0; orientation, 1). Approximately 1½ hours after stopping the propofol infusion, the patient began to exhibit withdrawal symptoms; and his CIWA score rose to 46. Because of returning signs and symptoms of alcohol withdrawal, the propofol drip was restarted at 5 ?g/(kg min) and titrated by 5 ?g/(kg min) every 10 minutes up to 20 ?g/(kg min), which abated the patient's symptoms; and the CIWA score returned again to 2.
