A patient with a known difficult airway was going to be extubated.The physician decided to use an 11 french cook cae.Using a bronch adapter while the patient was still being ventilated.The doctor says that the markings on the catheter only go to 35cm - the physician likes to go to 25cm at the mouth but couldn't see the numbers at the mouth nor could they be seen at the top of the bronch adapter.The physician was trying to guess on his depth since the markings only go to 35cm and could not see how deep in the patient's airway the device was.It turns out the device was only approximately 15cm in the patient's airway and the catheter fell out.Unfortunately, the patient did require reintubation but could not be and ended up having a cricothyrotomy.The physician feels if the cae had a higher depth markings that this would help with the safety of the product as a double check to let them know how deep the catheter is.The physician stated if markings up to 65cm would be helpful.
