- Conditions
- AnesthesiaCesarean Delivery Affecting NewbornInflammatory Response
- Interventions
- Diagnostic Test: HSCRP and NLR
- Registration Number
- NCT03594695
- Lead Sponsor
- Ufuk University
- Brief Summary
The stress response to surgery is a result of tissue injury with local and systemic inflammation that contributes to the postoperative outcome. Anesthesia is known to effect perioperative stress response Regional anesthesia modifies stress response through afferent blockage whereas general anesthesia affects the stress response via central modulation. High sensitive C-reactive protein and neutrophil to lymphocyte ratio are used for evaluation of inflammation. The aim of this study was to document the value hs-CRP and NLR in perioperative stress response in two different anesthesia methods applied to term pregnant women undergoing elective ceserean section (C/S).
- Detailed Description
The stress response to surgery is a result of tissue injury with local and systemic inflammation that contributes to the postoperative outcome. Anesthesia is known to effect perioperative stress response. Regional anesthesia modifies stress response through afferent blockage whereas general anesthesia affects the stress response via central modulation. High sensitive C-reactive protein and neutrophil to lymphocyte ratio are used for evaluation of inflammation. The degree of systemic inflammation has been determined by numerous pro- and anti-inflammatory cytokines.The cytokines control the release of C -reactive protein (CRP) which is an acute phase reactant produced by the liver. CRP is a widely used marker of inflammation and tissue damage. High sensitive C -reactive protein (hs-CRP), is a more sensitive assay for detection of inflammation measured by particle-enhanced immunonephelometry . A rapid increase in hs-CRP may indicate inflammation and tissue damage . Another well-known indicator of inflammation is neutrophil-to-lymphocyte ratio (NLR). NLR correlates strongly with elevated plasma levels of circulating proinflammatory cytokineS. The aim of this study was to document the value hs-CRP and NLR in perioperative stress response in two different anesthesia methods applied to term pregnant women undergoing elective ceserean section (C/S).
