Dear Bhupendra,

Please find below some universities and institutes offering the course of Operation Theatre Technician in Indore and Madhya Pradesh. 

MGM Medical College (MGMMC), Indore (Offers Certificate course)- It's an old institution established in the 1940s and is run by the government. So, by corollary, you can expect a good level of education here. Then there are Chirayu Medical College Hospital, Bhopal, which offer Certificate in Operation Theatre Technician, and then new and upcoming AISECT University, Bhopal which also offers a course in the subject. 

I hope it gives you some options to begin your exploration towards pursuing the course. 

Good Luck!
