Abstract

Background:

This study assessed effect of administration of high-concentration supplemental perioperative oxygen on systemic inflammatory and immune response in patients undergoing elective laparoscopic cholecystectomy.

Materials and Methods:

One hundred seventy-seven patients were assigned randomly to an oxygen/air mixture with a fraction of inspired oxygen (FiO2) of 30% (n=88) or 80% (n=89). White blood cells, peripheral lymphocytes subpopulation, human leukocyte antigen-DR, neutrophil elastase, interleukin (IL)-1 and IL-6, and C-reactive protein were investigated.

Results:

Significantly higher concentration of neutrophil elastase, IL-1, IL-6 and C-reactive protein was detected postoperatively in the 30% FiO2 group patients in comparison with the 80% FiO2 group (P<0.05). Statistically significant change in human leukocyte antigen-DR expression was recorded postoperatively at 24 hours, as a reduction of this antigen expressed on monocyte surface in patients from 30% FiO2 group.

Conclusions:

This study demonstrated that high-concentration (80%) supplemental perioperative oxygen can lead to a reduction in postoperative inflammatory response and avoid postoperative immunosuppression.
