Understanding Modern Operation Theatres

An operation theatre, or OT, is a complex sterile environment for safely conducting surgeries. It integrates surgical and anesthetic equipment. An ideal OT is located near related departments like emergency, blood bank, and intensive care. OTs can be classified as ultra sterile, sterile, or septic based on sterility levels. They can also be modular or non-modular based on construction. Key requirements of an OT include strict temperature, humidity, ventilation, and air filtration controls to maintain sterility. The OT suite has defined sterile, clean, protective, and disposal zones to segregate different sterility levels. Features like non-porous floors, seamless walls and ceilings, laminar airflow, medical gases

• Must conform to basic parameters so as to
maintain the sterile OT environment
• Zones in the OT based on sterility
– Sterile/ultra sterile
– Clean
