What is Diploma in Operation Theatre Technology (DOTT)?
Diploma in Operation Theatre Technology (DOTT) is an allied-health programme that prepares students for technical and support responsibilities within operation theatre and perioperative environments. Students learn how operation theatres are organized and prepared, how surgical instruments and equipment are handled, how sterilization and infection-control procedures are followed, and how patients are supported before, during and after surgical procedures.
The programme also introduces anaesthesia drugs and equipment, special OT tray setup, surgical procedures, emergency care, patient monitoring, OT ethics, safety and the role of the theatre assistant. DOTT training develops technical discipline, attention to detail, teamwork, communication, infection-control awareness and safe workplace practices.
The programme combines classroom education, practical OT simulation training and supervised hospital exposure. Students develop foundational skills in operation theatre preparation, surgical instruments, sterilization and disinfection, infection control, patient preparation, anaesthesia equipment orientation, surgical assistance and safe OT practices.
