title: Rational treatment of hypotension after carotid endarterectomy by carotid sinus nerve blockade.
abstract: Intraarterial blood pressure was monitored continuously for the first 24 postoperative hours in twenty consecutive patients subjected to carotid endarterectomy. Ten patients developed postoperative hypotension not attributable to hypovolaemia, depressant drugs, myocardial impairment or arrythmias. The postoperative hypotension was readily reversed by local blockade of the sinus nerve on the operated side. This blockade was accomplished by the injection of 2 ml of Lignocain (1%) through a catheter placed with its tip in the vicinity of the sinus nerve at the carotid bifurcation. It is concluded that the postoperative hypotension is due to increased activity in the sinus nerve and that this hypotension should rationally be treated by carotid sinus nerve blockade.
