Online published on 16 September, 2020. Abstract Aim To study the effect scalp block given with 0.5% bupivacaine on early hemodynamic changes in patients who were to undergo craniotomy. Methods The study was conducted as a randomized experimental prospective Study on 40 adult patients of both sexes till 70yrs of age with an American Society of Anaesthesiologists (ASA) physical status I, II who were to undergo elective craniotomy. After obtaining institutional ethical clearance and written consent of the patients, they were then randomly grouped into 2 using a computer generated table of numbers. Group S, received 20ml 0.9% normal saline, n=20 and Group B received 20ml 0.5% bupivacaine, n=20. Patients were intubated and scalp block was performed 15 minutes prior to craniotomy. The mean arterial pressure (MAP), heart rate (HR) of the patients were recorded prior to and till half an hour post craniotomy. Chi- square test was used to analyse data. Statistical significance was considered if P value was less than 0.05. Result During the infliction of a painful stimulus, Group S showed a significant difference (p<0.05) in comparison to group Bin terms of the MAP, the HR and also with the baseline within the same group. Conclusion To conclude, we can say that scalp block ensures the stabilization of hemodynamic responses by reducing the sympathetic response during early craniotomy. We think that Injection Bupivacaine 0.5% can be effectively used for achieving this early haemodynamic stability in scalp block procedures.
