Comparing the efficacy of Morphine alone with Morphine and mgso4 in pain management after coronary artery bypass surgery

Objective: To compare the effectiveness of Morphine alone and Morphine with MgSo4 in pain management after CABG surgery.

Methods: This randomized control trial was conducted in the department of anesthesia and critical care Choudhary Pervaiz Ellahi Institute of Cardiology, Multan from November 2016 to June 2017. All collected data was entered and analyzed by using computer software SPSS version 23.1. Quantitative data like age, VAS score was analyzed and presented as mean and standard deviation. Similarly qualitative data like gender and ASA status was calculated and presented as frequency and percentages. Independent sample T-test was applied for significance of VAS score. P value ≤0.05 was considered as significant.

Results: A total number of 150 patients of both genders were included in this study. The main outcome variables of our study were VAS score. It was observed that, in group (M), the mean VAS score after 4, 12 and 24 hours of operation was 5.24±1.61, 5.8±2.27 and 5.44±2.27 respectively. And in group (MM), the mean VAS score after 4, 12 and 24 hours of operation was 4.36±2.58, 3.48±2.10 and 4.12±1.05 respectively. It was noted that both groups had statically significant difference of VAS score, as group (M) had higher VAS score than group (MM).

Conclusion: Morphine with Mgso4 has better efficacy as compared to morphine alone when used as analgesic agent after CABG surgery.
