A new gas jet method for the assessment of sensory block after spinal anaesthesia.
We evaluated a new method of assessing sensory block after spinal anaesthesia using a fine gas jet and compared it with other established methods. The gas jet method was used to test the block before and after surgery and was found to compare favourably with pin-prick (median difference 0 and 0 dermatomes) and ethyl chloride (median difference 0.5 and 1.0 dermatomes) but less well with cotton wool (median difference -2.0 and -2.0 dermatomes).
