30 yr old ASA I patient was scheduled for lipoma excision. Anaesthesia was induced with propofol, fentanyl and oxygen mask with nitrous oxide and sevoflurane. A classic LMA was introduced subsequently with IPPV by hand as the patient remained apneic.Desaturation and high airway pressure followed by difficulty in ventilation . The LMA was removed and mask ventilation commenced which rectified the problem. Again on reinsertion of the same LMA resulted in difficulty of ventilation and absent ETCO2 tracings.A proseal LMA was then inserted and anaesthesia went uneventful. On careful examination of the lumen of the classic LMA revealed an impacted living foreign body, a beetle which might have crawled in, the prepared LMA from the induction room
COCKROACHES, SPIDERS AND CENTIPEDES BEING THE COMMON LIVING CREATURES FOUND IN ANAESTHESIA CIRCUITS. EVENTHOUGH IT IS COMMON THAT LIVING FOREIGN BODIES CAN ENTER INTO ANAESTHESIA CIRCUITS, IT IS QUITE UNCOMMON TO FIND THEM IN ANAESTHESIA MACHINE.WATCH THIS INTERESTING PHOTOGRAPH WHERE YOU CAN SEE A LIVING FOREIGN BODY IN FOW METER
ROUTINE CHECK FOR ANAESTHETIC BREATHING SYSTEMS IS MANDATORY BEFORE INDUCING ANAESTHESIA AS THESE LIVING FOREIGN BODIES CAN BE AN UNCOMMON CAUSE FOR BREATHING CIRCUIT OCCLUSION, AND THEREBY CAUSING HYPOXIA AND SOMETIMES MAKE YOU THINK OF THE POSSIBILITY OF SEVERE BRONCHOSPASM OR PNEUMOTHORAX IN VIEW OF HIGH AIRWAY PRESSURE AND RAPID DESATURATION .
