Abstract :

BACKGROUND AND AIMS: To study and compare the hemodynamic stress response to skull pin insertion following scalp block with 0.5% bupivacaine v/s 0.5% ropivacaine in patients undergoing craniotomy for intracranial tumours. MATERIALS AND METHODS:The study was done in patients of age between 18 to 60 years of ASA–I and II status of both sexes presenting for elective craniotomy for intracranial tumours.The patients were assigned to two groups of 25 patients each? Group–I patients: Received 20 ml 0.5% bupivacaine (100mg).Group–II patients: Received 20 ml of 0.5% ropivacaine (100mg). RESULTS: The observed hemodynamic variables such as heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure and spo2 at various time intervals in both the groups showed a statistically significant (p<0.05) difference in anova and tukey Kramer method of statistical analysis. CONCLUSION: As both 0.5% bupivacaine and 0.5% ropivacaine, when used in scalp block to attenuate the stress response to skull pin placement in craniotomy patients showed statistically significant p<0.05% and has no superiority of either of the drug in attenuating the hemodynamic stress response to skull pin placement over each other, 0.5% ropivacaine is preferable instead of 0.5% bupivacaine in view of its better cardio stability over bupivacaine.
