Immunomodulatory effects of anaesthetic sevoflurane in septic mouse model

Abstract

Sepsis is one among the dangerous medical threat that is very much related to body’s immune system having no proper treatment for this condition. About19 million cases of sepsis have been recorded and out of which 5 million cases die every year. Sevoflurane other than controlling the depth of anaesthesia, it does have a vital role in immunomodulations. The study is focused on investigating the immunomodulatory effects of sevoflurane in the septic mouse model induced by CLP. Mortality rate, organ damage, inflammatory mediators, bacterial load, coagulopathy, hepto and renal functional changes, serum lactate, blood glucose, neutrophil sequestration and finally histopathological examination were investigated. The results were interesting that exposure to sevoflurane improves the polymicrobial abdominal sepsis outcome. Mice exposed to sevoflurane after CLP significantly improved outcomes of polymicrobial abdominal sepsis and reduced mortality by improving overall 7-day survival (83.3%) compared to mice without sevoflurane (no treatment group 16.6%) additionally decreasing the surrogate marker levels in the experimental sepsis animal model conducted. Our study suggests that the selection of certain anaesthetic drugs could be critical in the management of septic patients because their immunomodulatory effects could be large enough to affect sepsis pathophysiology.

Comparison of High-Normal Versus Low-Normal Mean Arterial Pressure at Target on Outcomes in Sepsis or Shock Patients: A Meta-Analysis of Randomized Control Trials

“…Sepsis has emerged as the primary cause of infection-related fatalities worldwide, affecting nearly 20 million individuals annually, resulting in over 10,000 daily deaths [ 1 , 2 ]. Notably, sepsis-related deaths surpass those from prostate cancer, breast cancer, and AIDS combined as per the data released by the Global Sepsis Alliance [ 3 ].…”

Association between different MAP levels and 30-day mortality in sepsis patients: a propensity-score-matched, retrospective cohort study

“…Sepsis is now the leading cause of death from infection in the world with nearly 20 million people suffering from severe sepsis every year [ 1 ]. More than 10,000 people die of sepsis-related complications every day [ 2 ]. According to the data released by the Global Sepsis Alliance, the number of deaths caused by sepsis exceeds the combined number of deaths related to prostate cancer, breast cancer, and AIDS [ 3 ].…”
