Role of oral clonidine on intraopereative haemodynamic stability for craniotomies of intracranial space occupying lesion.

This was an analytical comparative study. Aim of this study was to observe the effect of oral clonidine on intra operative haemodynamic stability in intracranial space occupying lesion (ICSOL) patients who underwent craniotomy. Total 60 patients were distributed into case and control group. Number of cases was 30 in each study group of this study. Mean age of experimental and control were significantly close to each other. Baseline weight, pulse, systolic blood pressure, diastolic blood pressure and mean pressure also showed a significant similarity between each group. Variable of each group was collected during different events of craniotomy. All variable of pulse, systolic blood pressure, diastolic blood pressure and mean pressure were tabulated by line chart and fluctuation of variable was measured by significance test. The fluctuation of mean pressure was respectively 11.6%, 11.2%, 12.4%, 11.4%, 14.2%, 15.6%, 10% and 9.4% in different events of craniotomy in hemodynamically unstable group and it was respectively 11.1%, 10.9%, 10.4%, 9.9%, 9.2%, 9.4%, 8.6% and 8.7% in hemodynamically stable group. 'P' value was less than 0.05. It was observed that fluctuation of haemodynamic parameters were significantly less in experimental group where oral clonidine was used as premedication.
