Fig 1. Changes in core temperatures during the study period in each group.

Circle blue line: control group (no insufflation); Square green line: warmed insufflation group (heating and humidification of the insufflation CO₂); Triangle orange line: forced air group (standard insufflation with lower-body warming blanket); Triangle red line: combination group (heating and humidification of the insufflation CO₂ in association with underbody warming blanket).Red Star stands at time after which the difference in temperature becomes significant across groups control group versus combination group i.e. 210 min.
