New study in the British Journal of Anaesthesia: Reusable warming blankets show a lower CO₂ footprint in the operating room

A study conducted at Amsterdam UMC and published in the British Journal of Anaesthesia (BJA) found that the reusable MOECK WARMING SYSTEM® evaluated in the study had a carbon footprint per surgical procedure that was up to 44% lower than that of the single-use systems evaluated. 
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 CO₂ break-even point compared with the single-use systems evaluated in the study was reached after only 5 to 9 uses.

The authors emphasize: In a scenario evaluated in the study using renewable electricity for both the operating theatre and reprocessing, the calculated carbon footprint of the reusable system was up to 74% lower.
