CSSD (Central Sterile Supply

Department)

Presented by: Dr Nirali Sheth

What is CSSD?

• CSSD can be defined as that services, within the hospital catering for sterile supplies to all departments, both to specialized unit as well as General Wards and OPDs.

• Mission: to have the right item, at the right place, at the right time, in the right condition and always render services.

• Receives, stores, sterilizes and distributes

Objectives of CSSD

• To provide optimum services to all departments that requires sterile supplies of instruments

• To train all employees in order to assure optimal sterile techniques and aseptic handling of all sterile items.

• To avoid duplication of costly equipments, which may be infrequently used.

• To record the effectiveness of cleaning, disinfection and sterilization process.

• To monitor and enforce controls necessary to prevent cross infection

contd..

• To maintain an inventory of supplies and equipments

• To stay updated regarding developments in the field.

• To provide safe environment for patients and staff.

- Wash in detergent solution with stiff

Bristle brush

- Inspection and drying

Machine- 1. Washer Disinfector

2. Ultrasonic Cleanser

Hand washing Personal protective Technique Equipment

STERILIZATION

• It is a process of freeing an article from all living organisms including bacteria, fungal spores and viruses.

• A material is pronounced sterile if it achieves 99.99% kill bacterial spores.

• 3 types of sterilizers are available in CSSD department of this hospital.

1. Steam Sterilizer

2. ETO (Ethylene oxide gas sterilizer)

3. Hydrogen peroxide plasma gas sterilizer.

STEAM STERILIZER (AUTOCLAVE)

• 3 machines are available in this department

2 manual and1 semi automatic

• Autoclaved instruments can

be valid for 7 days.

Operation:

• Preparation of load

• Loading the chamber

• Autoclave cycle

A)Preparation of Loads:

• The cleaned and disinfected instruments are brought to the packaging area

• Linen packs: The packs is wrapped using two layers of material

• Pack is sealed with autoclave tape( Indicator) and labeled with date, content, cycle and operator.

• Pouch packs: used for single instrument Pouches are heat sealed and rolled and labeled.

B)Chamber loading

C)Autoclave cycleAt high temperature 134`c,30 psi pressure-7 minAt low temperature 121`c, 30 psi pressure- 20 min

ETHYLENE OXIDE GAS STERILIZER

2 ETO sterilizers- 1 manual &

1 automatic

• Here automatic machine uses

100 gms of ETO gas cartridge

• Manual machine uses 40gms

of ETO gas cartridge

Contd..

• Thermal paper roll for printer and gives printed details of each cycle

• 12 hours of cycle and 6 hours aeration period

• 1 year validity for sterilized instruments

• Label over sterilized items should contain sterilization date and expiry date with signature of head.

PLASMA STERILIZER

In this department, a hydrogen peroxide plasma gas sterilizer is available

Identified Advantages:

• Materials and device compatibility

• Rapid turnaround times

• In-house control of sterilization

• Lower inventory requirements

STEPS FOR PLASMA STERILIZATION

1. The Vaccum Phase:

• The chamber is evacuated, reducing internal pressure in preparation for subsequent reaction

2. The Injection Phase"

• A measured amount of liquid hydrogen peroxide is injected into the chamber, evaporating the aqueous hydrogen peroxide solutions and dispersing it into the chamber where it kills bacteria on any surface it can reach.

Contd..

3.Diffusion Phase:

• The hydrogen peroxide vapour penetrates the chamber, exposing all load surfaces to sterilant and rapidly sterilize devices and materials without leaving any toxic residue

• At the completion of this phase,the chamber pressure is reduced and the plasma discharge is initiated.

Contd..

4. Plasma:

• An electromagnetic field is created in which hydrogen peroxide vapour breaks apart, producing low temperature plasma cloud that contains ultraviolet light and free radicals

• Following the reaction, the activated components lose their high energy and recombine to form oxygen and water.

Contd..

5. Vent Phase:

• The chamber is vented to equalize the pressure enabling the chamber door to be open.

• There is no need for aeration or cooldown. Devices are ready to reuse immediately.

Long cycle takes 72 mins and short takes 52-55 mins

Tylveks packet roll is used for packaging

The sterilized instruments are valid for 3 years.

QUALITY INDICATORS

Quality indicators are used and maintained by CSSD senior manager in this hospital

• Bowie Dick type test

• Steam indicator

• Chemical indicator for sterilizing steam

• Biological indicator for Steam, ETO and Plasma sterilizer

• ETO indicator for ETO sterilizer

• Plasma indicator for plasma sterilizer

RECORD MAINTENANCE

• In the CSSD, they are maintaining 3 registers regarding duties allotment and technician and attendants attendance register.

• It is also recorded in a departmental computer.

• CSSD register is implemented with CSSD reference number and maintained well from each and every department before sterilization and after sterilization so recall procedure can be done easily in case of problem in sterilization.

1.Orthopedic OT Autoclave and ETO cycle register

2. Cathlab, trauma and cardiac OT register

3. Wards ETO and Autoclave

4. Plasma cycle record

5. ETO cycle register

6. Autoclave cycle register

• The departmental head indent materials from general store and they will provide it according to needs

• In case of problem in any machine, the department head will contact Bio medical engineering department and a company man for repairing.

SUGGESTIONS

• Ideally CSSD should be unidirectional

• There is less space available for this department

• It should be airconditioning.
