Email: [email protected] Abstract Hospital admission, anesthesia and surgery are stressful experiences for children which may lead to psychological trauma and personality changes. The increasing use of day care surgery, the avoidance of parental separation and the use of sedative premedica tion may reduce the stress of hospitalization in children and the risk of adverse psychological sequel. Search for an ideal premedicant drug for children is still on. Aims and objectives: To compare and evaluate the efficacy of midazolam and triclofos when given orally as premedicants in children. Materials and methods: In the present study 50 children were selected and were divided in two groups (midazolam group and triclofos group). Preoperative assessment was performed one day before the surgery by an ob server. Evaluation of post-premedication sedation (thirty minutes post-premedication in the Midazolam group and sixty minutes post -premedication in the Triclofos group) was recorded. Level of sedation at the post premedication and level of sedation at the time of separation from parents was recorded. Behavior at the time of separation from parents and behavior during mask acceptance was recorded and analyzed. Results: On Post Premedicant it was observed that in midazolam group majority children (22) had se dation score of two whereas in triclofos group majority of the children (21) had sedation score four . Evaluation of the level of sedation at the time of separation from parents showed that majority of the children (22) in the Midazolam group had a sedation score of two whereas in triclofos group majority of the children (20) were having score four. The comparison of sedation scores between the two groups was done using the Fisher’s exact probability test. The difference between the two groups was very highl y significant statistically. While studying behavior at the time of separation from parents, it was observed that majority of the children in midazolam and triclofos were having score four (21 and 23 children respectively). In the Midazolam group, 14 child ren had a mask acceptance score of four and in the triclofos group, 20 children had a mask acceptance score of four. Conclusion: Even though the children are less sedated with oral midazolam as compared to triclofos, if produces an equally satisfactory sep aration from parents and satisfactory mask acceptance.
