Propofol Autocoinduction and Midazolam Co-induction for Propofol Induction

Abstract

Intoduction: The problem with induction during anaesthesia is decrease in blood pressure, apnea which could be detrimental to patient. Co-induction and autocoinduction are one of the modalities that are developed to overcome hypotension during induction. The study was carried out to observe heart rate, blood pressure response and propofol consumption following midazolam as co-induction or propofol autocoiniduction for propofol induction. Methods: This study was a conducted in 52 patients of ASA I and ASA II undergoing elective surgical procedures with general anesthesia. Patients were randomly allocated and group P received 0.5 mg/ kg of propofol and group M received 0.04 mg/ kg of midazolam intravenously as autocoindution and coinduction respectively. Results: The two groups were identical regarding age, weight, ASA status and base line vitals. This study showed that there was significant difference between 2 groups in terms of blood pressure. Decrease in blood pressure from baseline is more in Midazolam group compared to propofol. In terms of Heart Rate there was no statistically significant between two groups at any time of observation. Decrease in HR from baseline was almost similar in both groups. Consumption of Propofol was not statistically significant different between two groups. Propofol group required 8% lesser Propofol than Midazolam group. Conclusions: Our study concluded that blood pressure was decreased significantly in Midazolam group compared to Propofol group but heart rate was decreased almost similar in both groups and was not statistically significant. Consumption of Propofol was not statistically significant but Propofol group had 8 % lesser Propofol consumption than Midazolam group.
