Introduction to Perioperative Theatre Instruments and Apparatus

Introduction to Peri‑operative Theatre Instruments & Apparatus
(Designed as a quick‑reference guide for students, theatre staff, and anyone new to the operating room environment)

1. Overview of the Peri‑operative Environment

2. Classification of Instruments

Tip: Instruments are usually color‑coded or numbered in sets to speed identification and reduce errors.

3. Core Apparatus in the Operating Theatre

3.1 Anesthesia Workstation

• Components: Gas supply (O₂, N₂O, air), vaporizers, ventilator, breathing circuit, monitoring module.
• Key Checks: Gas flow, leak test, ventilator alarms, vaporizer calibration.

3.2 Surgical Tables

• Features: Adjustable height, tilt, Trendelenburg/Reverse Trendelenburg, radiolucent surface for imaging.
• Safety: Secure patient positioning devices (gel pads, straps) to prevent falls.

3.3 Lighting Systems

• Overhead Surgical Lights: Adjustable intensity, color temperature ~4,300 K, shadow‑free illumination.
• Auxiliary Lights: Headlamps, fiber‑optic illumination for deep cavities.

3.4 Electrosurgical Units (ESU)

• Modes: Cutting, coagulation, blend, bipolar, monopolar.
• Safety: Grounding pad placement, current settings per tissue type, smoke evacuation.

3.5 Suction & Irrigation Devices

• Suction: Wall‑mounted or portable units, Yankauer, Frazier, and deep suction tips.
• Irrigation: Pulsed lavage, gravity‑driven systems, sterile saline bottles.
