Inhaled sevoflurane for lower gastrointestinal endoscopy with possible propofol anaphylaxis.

Sedation with propofol is widely used for the outpatient examination. Although anaphylaxis to propofol is rare, there were some reports of anaphylaxis following propofol administration. We present a case of female patient under sedation for lower gastrointestinal endoscopy with possible propofol anaphylaxis. Then sevoflurane was successfully used for the examination and the following surgery. We discussed the possible feasibility of sevoflurane for the examination of lower gastrointestinal endoscopy. Propofol is widely used for the sedation of outpatient with lower gastrointestinal endoscopy. But it may cause some allergic reaction. Inhaled sevoflurane may provide a satisfactory and safe alternative for adult outpatients' endoscopy.
