INTRODUCTION

  • LASER- Light Amplification by Stimulated Emission

of radiation.

  • Light emitted by Laser is non ionizing, electromagnetic radiation

Why Laser safety program

Lasers technology is evolving and clinical application is broadening.

Increasing use in cataract surgery, skin lesions,vericose vein treatment, laser lithotripsy

Pose potential hazard for patients and staff if safety procedures are not established and followed (JCI ,2021)

Purpose and scope

  • Management of classes 3B and 4 which carry the

most significant risk for harm to minimize risks

  • Cause electrical, skin and eye injuries

5 of 17

TEAM

  • Laser safety committee - overall policy and operational oversight over the laser safety program
  • LSO – coordinates the program and reports to laser safety committee
  • Biomedical engineering - responsible for equipment requisition, evaluation, installation, operator training, preventive and corrective maintenance
  • Line staff (Users) comply during use and reporting of incidences

6 of 17

Laser safety officer

  • Conduct laser audits
  • Ensure valid credentials for RNS and physicians
  • Education sessions has been planned
  • Laser operating manuals and policy are easily accessible
  • PPEs are maintained and stored appropriately

CLASSES OF LASER

8 of 17

Laser injuries

  • Classes 3B and 4 are related with significant safety risks, ocular injury, dermal injury and fire.
  • Effects to the eye - Retinal burns, corneal burns, photo keratitis, visual effect (blindness).
  • Skin injury –Can result direct or from reflected laser light, Skin may become dry, itchy or charred.
  • Include – erythema, delayed effects e.g. CA skin, thermal skin burns.

Non beam hazards

  • Non direct exposure to laser beam
  • Electrical hazards
  • Fire
  • Noise especially pulsed lasers
  • Collateral radiation
  • Cryogenics
  • Plasma radiation
  • Explosions

Model for Improvement: PDSA Cycle

Establish the objectives and processes necessary to deliver results in accordance with Laser safety requirements

  • Risk assessment
  • Purpose
  • Objective setting

Monitor and measure those objectives and processes and report the results: KPI i.e trained staff,compliance ,fire incidences,injury ,infections

Take the actions needed to continually improve the process performance: Report incidences,RCA

Implement those objectives and processes

  • Train OR Personel
  • Avail appropriate PPE

To patient and staff

  • Signage

Laser intraop form

DO & DON’TS

1.Patient eye protection:

  • Spinal/L/A : laser googles
  • G/A: saline moistened eye pads secured with tape

2.Skin protection:

  • Do not use alcohol-based skin preparation solution
  • Use saline wet packs to protect adjacent tissues and absorb laser energy when in cavities
  • Physician to wear gloves and a gown to prevent chronic skin exposure
  • Do not touch the tip of the accessory may become hot during surgery causing tissue damage
  • Do not put on reflective jewelry – both user and patient

DO: Electric hazards

Always check power cords for integrity prior to plugging into outlet

Never open any panel on laser units

If any leaks are noted shut off machine immediately

Document the incidence

13 of 17

DO & DON’TS :Environmental safety

Place LASER specific signs to all entryways of OR

01

Close all doors

02

Place protective coverings over the door glasses

03

Avail goggles

04

Do not leave machine unattended when on ready mode

Types of Laser controls

1.Engineering - in-built safety features supplied by manufacture.

    • Guarded foot switch/Housing interlocks
    • stand by controls and emergency switch.

2.Procedural - policies and procedures in facilities.

    • Operational activities specific to equipment and practice.
    • E.g. Ocular protection, controlled access to the OR.

3.Administrative controls:

Development of documentation tools,LSO appointment ,Compliance with occupational health and safety rules and training of personnel.

15 of 17

MONITORING:

  • Quarterly report from the LSO to facility Management services which includes:
    • Monthly KPI report( training, injury and other incidences)
    • Audits
    • Spot-checks on compliance during laser use
