Effects of Insufflated Gas on Core Temperature and Post-operative Pain During Laparoscopic Surgery

2014-07-24 14:23:59 | BioPortfolio


During laparoscopy, administration of cold and dry carbon dioxide (CO2) leads to hypothermia. Different types of gas conditioning have been studied in order to prevent this specific hypothermia. Intra-abdominal administration of local anesthetics has also been studied in order to prevent post-operative pain. In both cases, some results have been described.

The investigators propose to evaluate in a prospective, randomized, double blind trial, the impact of 4 different types of conditioning of insufflated gas during laparoscopy for womb surgery on hypothermia prevention and post-operative pain. These 4 types of gas conditioning are:

- CO2 wet and warm with nebulized ropivacaïne

- CO2 wet and warm without nebulized ropivacaïne

- CO2 dry and cold with nebulized ropivacaïne

- CO2 dry and cold without nebulized ropivacaïne

The investigators use a new device (Aeroneb® Pro [Aerogen® Company]) which can wet (by nebulization) the insufflated gas and therefore permits intraperitoneal medicament administration (local anesthetics).
