Anaesthesiology & Modular Operation Theatre

Chandan Hospital is having 4 Modular Operation Theatres with Pre-operation and Post-operation wards having 12 beds. Anaesthetic Machine has vaporizers, ventilators, an anesthetic breathing circuit, waste gas scavenging system and pressure gauges. The purpose of the anesthetic machine is to provide anesthetic gas at a constant pressure, oxygen for breathing and to remove carbon dioxide or other waste anesthetic gases. Intravenous anesthetic is delivered either by bolus doses or an infusion pump. There are also many smaller instruments used in airway management and monitoring the patient.

Anaesthesia is a state of temporary induced loss of sensation or awareness.

Three broad categories of anaesthesia exist :
  • General anesthesia suppresses central nervous system activity and results in unconsciousness and total lack of sensation.
  • Sedation suppresses the central nervous system to a lesser degree, inhibiting both anxiety and creation of long-term memories without resulting in unconsciousness.
  • Regional anesthesia and local anesthesia , which block transmission of nerve impulses between a targeted part of the body and the central nervous system. A patient under regional or local anesthesia remains conscious.
Two broad classes exist :

Peripheral blockade inhibits sensory perception in an isolated part of the body, such as numbing a tooth for dental work or administering a nerve block to inhibit sensation in an entire limb. Central, or neuraxial, blockade administers the anesthetic in the region of the central nervous system itself, suppressing incoming sensation from outside the area of the block. Examples include epidural anaesthesia and spinal anaesthesia.

Modular operating rooms are spacious, easy to clean, and well-lit, typically with overhead surgical lights, and have viewing screens and monitors.

Operating room equipment :

  • The operating table in the center of the room can be raised, lowered, and tilted in any direction.
  • The operating room lights are over the table to provide bright light, without shadows, during surgery.
  • The anesthesia machine is at the head of the operating table. This machine has tubes that connect to the patient to assist him or her in breathing during surgery, and built-in monitors that help control the mixture of gases in the breathing circuit.
  • The anesthesia cart is next to the anesthesia machine. It contains the medications, equipment, and other supplies that the anesthesiologist may need.
  • Sterile instruments to be used during surgery are arranged on a stainless steel table.
  • An electronic monitor (which records the heart rate and respiratory rate by adhesive patches that are placed on the patient's chest).
  • The pulse oximeter machine attaches to the patient's finger with an elastic band aid. It measures the amount of oxygen contained in the blood.
  • Automated blood pressure measuring machine that automatically inflates the blood pressure cuff on patient's arm.
  • An electrocautery machine uses high frequency electrical signals to cauterize or seal off blood vessels and may also be used to cut through tissue with a minimal amount of bleeding.
  • Operation Theatres are having fully automated doors and digital Scrub facilities.
  • In Operating theatres, laminar-flow systems are used with high-efficiency particulate air (HEPA) filters where particles >/=0.3 microm are removed.
