“…Chakithandy et al, described a case report with a hypertensive crisis after an interscalene blockade. The hypertension remained to be persistent due to the failure of a contralateral carotid sinus body reflex compensation [10]. The blood pressure did not remain persistently high in our cases, which reflected the compensatory control mechanism of the contra lateral carotid body receptor.…”

We would like to report 2 cases where we encountered a rare complication of hypertension without tachycardia after the administration of an interscalene block. We have tried to explain the same with the anatomical correlations.Sameer mahamud Jahagirdar, C. raJeSh Prabhu, S. ParthaSarathy InTRoduCTIon Case capsule 1:A 55 year old male patient had a history of the fall of a coconut on his left arm and he had sustained a fracture on the mid shaft of the humerus. He was posted for the open reduction and the internal fixation of the left humerus. The preoperative evaluation of the patient revealed a pulse rate of 62 per min, a regular and a blood pressure of 170 / 90 mm Hg and a respiratory rate of 18/ min. Electrocardiography revealed left ventricular hypertrophy by the voltage criteria and 2 D echocardiography showed a grade I diastolic dysfunction, no regional wall motion abnormality, and a trivial aortic, mitral and tricuspid regurgitation with no clots in the chambers. The other systemic examinations were unremarkable. The laboratory investigations revealed anaemia (a haemoglobin concentration of 7.1), which was optimized with blood transfusions. The other investigations were unremarkable. The patient was optimized with the cardiac medications; Tab. Atorvastatin 20 mg OD and Tab. Amlodipine 2.5 mg OD for a week and he was then taken for surgery.

“…The disturbances in the autonomic nervous system after an interscalene block due to the blocked carotid body baroreceptors have been described, which clinically correlate as severe hypertension [10]. The hypertension without tachycardia is observed with a carotid sinus blockade, which is due to the local anaesthetic agents experimentally [11].…”
