Spinal anaesthesia for emergency Caesarean section in an achondroplastic patient.

modifications are widely accepted, used and even published in the journals [2]. The modification of the ProSeal LMA by connecting an endotracheal tube connector to the drain tube has been reported recently, when the lightwand was used in conjuction, to facilitate the insertion of the ProSeal LMA, as the endotracheal tube connector seats perfectly in the connector lock at the hilt of the lightwand. The author of this article stressed that the endotracheal tube connector must be removed immediately after the procedure to prevent inadvertent connection of the anaesthetic circuit to the drain tube [3]. This ProSeal LMA is an essential item on our difficult airway trolley, as recommended in the Difficult Airway Society guidelines for unanticipated difficult intubation during rapid sequence induction in non-obstetric patient. In our case, the endotracheal tube connector was found to be firmly attached to the drain tube. The reason for this could not be determined: Either the ProSeal LMA was modified to be used with lightwand or an endotracheal tube connector was attached in error before sending for sterilization. All staff have been made aware of this, to prevent any future incident. This incident highlights the importance of a thorough check of all the equipment before sending for sterilization as well as before use in the theatre. Airway devices should be checked not only for its patency but also for any inadvertent modifications.
