Abstract Background  Body core temperature is an important vital parameter during surgery and anaesthesia. It is influenced by several patient-related and surgery-related factors. Laparoscopy is considered beneficial in terms of a variety of parameters, for example, postoperative pain and length of hospital stay. Non-humidified, non-warmed insufflated C ­ O2 applied during laparoscopy is standard of care. This prospective observational trial therefore evaluates the impact of non-humidified ­CO2 at room temperature on abdominal temperature and its correlation to body core temperature. Methods  Seventy patients undergoing laparoscopic surgery were included in this prospective observational study. Temperature was measured oesophageal and abdominal before induction of anaesthesia (T1), right before skin incision (T2), 15 min, 30 min and 60 min after skin incision. All patients were treated according to actual guidelines for perioperative temperature measurement. Results  Body core temperature and abdominal temperature correlated moderately (r = 0.6123; p
