Utilization of gas heater humidifier in the course of coelioscopies

The increasing utilization of coelioscopic interventions has needed the use of a larger number of trocars, which involves in some cases (especially at the beginning of personal experience) longer operations. In our clinical experience we have met hypothermies that compelled us to modify our way of working. The use of conventional means (like warming cushion, warming of irrigation fluids) could limit the temperature loss only moderately. So we imagined to warm and moisten the gases insufflated into the peritoneal cavity. We give a description of the accessories and the results with some patients.
