This document discusses patient warming systems used during anesthesia and surgery to prevent hypothermia. Induction of anesthesia can decrease core body temperature by over 1.5 degrees Celsius in the first hour. Forced air warming blankets are more effective at conductive warming than static blankets. Hypothermia can lead to complications like coagulation issues, increased oxygen consumption, cardiac issues, and prolonged hospital stays. Warming blankets are available for different body parts and surgeries, and new systems aim to rapidly induce heat transfer and prevent bacterial growth and burns.

2. WHY A PATIENT WARMER
• Reduction of heat loss from the skin is the most
promising approach to avoid Hypothermia.
• Induction of Anaesthesia can lead to a decrease in
core temperature of more than 1.5 degree Celsius
in the first hour of Anaesthesia.
• Measurement of the core temperature rather than
heat flux (heat transfer).
• Conductive warming of posterior surface to be less
efficient than forced air warming system.

3. HYPOTHERMIA - CONSEQUENCES
• Intra operative disturbance in coagulations.
• Raises post operative oxygen consumption due to
shivering.
• Cardiac Morbidity
• Wound Infection
• Prolonged hospital stay

4. RISKS
• Thermal Burns.
• Active warming of ischemic areas to be avoided.
• Post operative patient discomfort.
• Bacterial Infection in the environment.

5. BLANKET USAGE
• Upper body blankets:
• During abdominal surgery and lower limb surgery.
• Covered area is 0.54sqm. Or 15-20% of body
surface.
• Lower body blankets:
• During upper limb surgery and chest surgery.
• Covered are is 0.35sqm.
• Access blankets for specialised surgeries.

6. • Full body blankets: (Non woven laminated fabric)
• General purpose.
• Paediatric blankets:
• Used in neonatal and paediatric patients.

7. DIFFERENT BLANKET CONFIGURATION

8. COCOON: ADVANTAGES
• 1000 hours life HEPA filter
• Air pickup from sides
• Status Indicator
• Hose Cover
• Rapid induction of heat transfer
• Blankets with uniform micro porous holes
(26 holes/cm)
• Multi size and multi compatible blankets
