OPERATION THEATRE

What is an operating theatre?

An operating theatre is where certain invasive surgical procedures – which means operations that involve cutting into and working inside a patient’s body – take place. This might involve either minimally invasive procedures like keyhole surgery – where cameras and a laparoscope are inserted through small incisions – or open surgery where surgeons make larger cuts to reach the internal organs. Complicated operations can last many hours.

Not all hospitals have operating theatres, and some larger hospitals might have more than one in what are called operating suites. Most operating theatres specialise in a certain type of surgery, such as heart or neurosurgery. These theatres will contain lots of specialist equipment, but every operating theatre has bright lights, an operating table for the patient to lie on, an Electrocardiograph Machine to monitor a patient’s heart-rate, and surgical suction machines to remove blood from around the organs the surgeons are treating.
It is also essential that operating theatres are completely sterile, which is why anyone who enters one must wear scrubs and a mask and wash thoroughly, to avoid spreading infection.

The stages of an operating theatre

Operations normally take place in four stages, which all require specialist staff:
  • Pre-operative stage is when patients are informed about and prepared for the operation about to take place, by restricting their diet for example
  • Anaesthetic stage is when the patient is either ‘put to sleep’ under general anaesthetic or has part of their body numbed under local anaesthetic
  • Surgical stage is when the operation is performed in the operating theatre
  • Recovery stage is when the patient is transferred to a ward for further care and treatment
Who works in an operating theatre?
Some of the staff who work in operating theatres include:
  • Surgeons who carry out the operation
  • Anaesthetists who give anaesthetics to control pain both before and during the operation
  • Theatre nurses who care for patients throughout all four stages of the operation
  • Operating department practitioners who make sure everything in the operating theatre is sterile and functioning properly, and may assist surgeons in the operation
  • Theatre support workers who transport patients between the wards and the operating theatre
  • Cardiographers to monitor the ECG machine
  • Radiographers to take X-rays if they are needed

SHREE SAI HOSPITAL Provides facility for operation theatre:

In Shree Sai Hospital we have fully equipped OT and CSSD (Central Sterile Supply Department). We have following types of sterilization

  • Autoclave: Steam sterilization
  • ETO (Ethylene Trade Oxide): All type of plastic and tubing are being sterilized with ETO as per the standards
  • STERRAD (Gas plasma sterilizer): We also have one of the advanced sterilization in which we sterilize all endoscopic and laparoscopic instruments. One of the advantage of this is sterilization is done within 30 minutes and the instruments can be used immediately.

Operating rooms: We have 3 operating theaters. Each theater is equipped to conduct most advanced and complicated surgery.

  • In OT we have well trained nurses to assist in latest endoscopic / laparoscopic surgery
  • OT environment is being periodically monitored by sending the surveillance swabs. These measures provide sterile environment and has resulted in minimal infection rate. So we use single dose antibiotics in most elective cases.
  • Strict aseptic precautions and sterile atmosphere is monitored with continuous airflow filtered by HEPA (High Efficiency Particulate Air) filters and the same has been monitored in all theaters.

Statistics: We perform approximately 1700- 1800 surgeries per year. Of these 34 are related to renal transplants.

Patient safety: We mainly focus on patient safety and these are some of the steps

  • Patient is identified with wrist identification tag and patient file in transfer bay
  • Time out (Patient name, Hosp. No and surgery side, antibiotics given) is being done by the Anesthetist in the presence of Surgeon and scrub nurse before starting surgery
  • OT temperature and humidity is monitored
  • We have Warm touch machine a to keep the patient warm, especially pediatric cases
  • We apply TED (Thrombo Embolic Devices) and SCD (Sequential Compression Device) during the prolonged surgery to avoid DVT(Deep Vein Thrombosis)

Equipments:

  • LASER for endoscopic treatment of Stone
  • C-arm machine for assisting in endoscopic surgeries
  • We use a state of Art Aspire anesthesia workstations along with S5 monitor is being used in all theaters
  • We also have the smallest endoscopes which can be used in pediatric cases
  • We have the Audio Visual system to record Endoscopic/ laparoscopic/ Open surgery cases as needed
  • Laparoscopy is the common procedure
  • ESWL facility is within the theater complex
