Equipment failure of intravenous syringe pump detected by in
Awareness is the recovery of consciousness during general anesthesia. It occurs when patients under general anesthesia receive inadequate anesthetic medications to maintain unconsciousness during surgery. Equipment failure is a common cause of intraoperative awareness. The present case has been reported in the journal Medicine.

A 16-year-old boy, 85 kg in weight, was admitted for thyroglossal cystectomy under general anesthesia. Six minutes after the intubation, it was noted that the Narcotrend index indicated a condition of light anesthesia and the patient was observed to be in tears.

He was diagnosed with Improper positioning of the syringe fixing clamp on the CP700TCI infusion pump caused equipment failure and light anesthesia.

Bolus of 50 mg propofol and 2 mg midazolam were administered manually by syringe, and inhalation of 2% sevoflurane was supplemented. Infusion pump was replaced. The Narcotrend index of the patient returned to state of deep anesthesia following manual administration of the anesthetic medications. Following the surgery, the patient had an uneventful recovery, and did not present with evidence of awareness.

Major takeway:_
- Users of the CP700TCI syringe pump should pay attention to the position of the syringe fixing clamp.

- Anesthesiologists should check all the equipment according to a defined checklist prior to anesthesia.

- Narcotrend monitor could help to detect light anesthesia and prevent potential awareness.
