A clear plastic backing was found in the throat of a patient.It was suspected that the backing was inadvertently inserted into the patient's throat during insertion of a laryngeal mask airway (undertaken by a consultant anesthetist) during surgery on (b)(6) 2019.The clear plastic backing was suspected to come from ambu ecg electrodes.Post surgery the patient experienced a sore throat, painful on swallowing, despite analgesic medication, an extended course of fungal treatment and a course of antibiotic treatment.During examination 17 days after the surgery, a plastic disc was detected at the base of the tongue.An ent surgeon retrieved the plastic backing with a flexible endoscope.This immediately resolved the patient's symptoms.A small excoriation was found on the patient's left lateral pharyngeal wall, which is expected to heal without problem.
