The customer reported that a patient treated earlier in the day had gone to the hospital due to swelling in the neck, no bruising or bleeding was reported.Customer subsequently reported that patient was administered a breathing tube which has since been removed.The customer reported that the patient was discharged form the hospital and returned home.Endodontist (customer/user) initially stated that swelling could have been due to an allergic reaction to anesthesia.The customer subsequently stated that it could be a sodium hypochlorite incident.The customer reported that during the procedure, the patient indicated feeling pain and thus the customer re-anesthetized the patient.After administering more anesthesia, the customer reported that he completed the procedure and noted that the results looked good.The customer reported that the patient was fine after the procedure and left the office without issue.Since the time of the initial event, the customer has noted that the patient's condition is improving.
