To determine whether the local anesthetic lidocaine and the volatile anesthetic isoflurane alter the active cellular and molecular programs governing the resolution of acute inflammation.
Evaluated inflammatory resolution dynamics in a zymosan-induced murine peritonitis model exposed to lidocaine or isoflurane.
Quantified polymorphonuclear neutrophil (PMN) apoptosis, macrophage efferocytosis, lipid mediators, and the rescue effects of a stable lipoxin A4 analog.
Performed systematic exudate proteomics using nanospray-liquid chromatography-tandem mass spectrometry to identify altered mediator and protein profiles.
Lidocaine delayed the onset of resolution by inhibiting PMN apoptosis and macrophage clearance, upregulating pro-inflammatory proteins (S100A8/9, CRAMP), and downregulating pro-resolving factors (IL-4, IL-13, TGF-β, Galectin-1).
Isoflurane promoted inflammatory resolution by attenuating PMN infiltration, shortening the resolution interval (Ri) by approximately 50%, and downregulating inflammatory chemokines, cytokines, CRAMP, and cofilin-1.
Administration of a stable lipoxin A4 analog partially rescued lidocaine-induced delays in inflammatory resolution.

No takes yet. Share an insight, caveat, or question.

Implication

Animal study reveals that lidocaine impairs while isoflurane accelerates inflammation resolution in mice, indicating that anesthetic choice directly modulates surgical recovery.
