The results of this study demonstrate that 60 mg of lidocaine sprayed down the tracheal tube before extubation and 40 mg sprayed down the tracheal tube before extubation and 40 mg sprayed down during tracheal tube removal prevents increases in blood pressure and pulse rate during and after extubation. The data suggest that this manoeuvre should be of advantage to patients with coronary artery disease who may not be able to tolerate the increased cardiac dynamics which usually accompany extubation.

The median as well as the ulnar nerve may be used effectively in the evaluation of neuromuscular blockade with the peripheral nerve stimulator. Both ulnar and median nerve stimulation produce flexion of the fingers. For maximum neural stimulation either during the routine use of the peripheral nerve stimulator or when it is used as an aid to peripheral nerve block, the negative pole should be attached to the exploring needle or over the nerve to be stimulated.
