Gas conditioning

Abstract

A method for reducing or preventing mesothelial cell damage by mixing a carrier gas and between 1 volume percent and 29 volume percent of nitrous oxide gas (N 2 O) to form a medicament and applying the medicament during surgery. The method can be used for prevention of adhesion formation, pain reduction, reducing or preventing acute inflammation, reducing or preventing CO 2 resorbtion or reducing tumor cell implantation upon surgery.

         32 . A method for reducing or preventing mesothelial cell damage during surgery comprising the steps of:
 mixing a carrier gas and nitrous oxide gas to form a medicament, wherein the nitrous oxide gas is between 1 volume percent and 29 volume percent, and   applying the medicament during surgery to reduce or prevent mesothelial cell damage.   
     
     
         33 . The method of  claim 32 , wherein the nitrous oxide gas is between 5 and 20 volume percent. 
     
     
         34 . The method of  claim 33 , wherein the nitrous oxide gas is between 5 and 10 volume percent. 
     
     
         35 . The method of  claim 32 , wherein the carrier gas is carbon dioxide gas. 
     
     
         36 . The method of  claim 33 , wherein the solubility of the carrier gas is larger than 0.5 g/l in water. 
     
     
         37 . The method of  claim 32 , wherein applying the medicament comprises flowing the medicament in or over a cavity during surgery in a cavity. 
     
     
         38 . The method of  claim 32 , wherein applying the medicament comprises flowing the medicament during pneumoperitoneum. 
     
     
         39 . The method of  claim 32 , wherein applying the medicament comprises flowing the medicament during open surgery. 
     
     
         40 . The method according to  claim 32 , wherein applying the medicament during surgery furthermore comprises applying the medicament for reducing or preventing pain. 
     
     
         41 . The method according to  claim 32 , wherein applying the medicament during surgery furthermore comprises applying the medicament for reducing or preventing acute inflammation. 
     
     
         42 . The method according to  claim 32 , wherein applying the medicament during surgery furthermore comprises applying the medicament for reducing or preventing CO2 resorbtion. 
     
     
         43 . The method according to  claim 32 , wherein applying the medicament during surgery furthermore comprises applying the medicament for reducing tumor implantation reduction. 
     
     
         44 . The method according to  claim 32 , wherein applying the medicament during surgery furthermore comprises applying the medicament for reducing or preventing adhesion formation.
