New study in the British Journal of Anaesthesia: Reusable warming blankets significantly reduce CO₂ footprint in the operating room

A recent study conducted at Amsterdam UMC and published in the British Journal of Anaesthesia (BJA) shows: The use of reusable warming blankets can reduce the carbon footprint per surgical procedure by up to 44%. 
In an independent Life Cycle Assessment (LCA), three commonly used forced-air warming blanket systems were analyzed, including the MOECK WARMING SYSTEM®. The study quantified the total CO₂ emissions per surgery, taking into account manufacturing, use, cleaning, and disposal.

Key findings

  • The reusable system produces 0.67 kg CO₂-equivalent per procedure
  • Single-use systems result in 1.05 kg and 1.3 kg CO₂-equivalent respectively
  • The ecological “break-even point” is reached after only 5 to 9 uses

The authors emphasize: Switching to renewable electricity in both the operating theatre and reprocessing facility reduces the carbon footprint of the reusable system by up to 74 %.
