Volatile anesthetics, while increasingly utilized in intensive care medicine, are associated with significant renal adverse effects. A critical safety concern—particularly with sevoflurane—involves its potential impact on renal function. Pathophysiologically, inorganic fluoride levels exceeding 50 µmol/L are recognized as a threshold for nephrogenic diabetes insipidus, a condition generally considered reversible. Additionally, the sevoflurane degradation product “compound A” has been implicated in direct renal tubular and glomerular toxicity. Specifically, exposure has been correlated with glomerular damage, evidenced by albuminuria, as well as injury to both proximal and distal tubules, indicated by elevated levels of α-glutathione-S-transferase. Postprandial glycosuria may also be observed. Unlike nephrogenic diabetes insipidus, the structural damage induced by compound A may result in irreversible renal impairment.

The early detection, diagnosis, anticipation, and therapy of infections to prevent sepsis and septic shock remain significant challenges in cases of grave burns. This narrative review explores various tools for early infection detection, including emerging biomarkers, the American Burn Association’s clinical criteria, and traditional blood parameters. A comparative study of the American Burn Association, Mann-Salinas, and Sepsis-3 criteria highlights the superior early detection capabilities of the Sepsis-3 criteria. However, the authors recommend that sepsis should be prospectively evaluated, identified, and classified by the intensive care group, rather than by relying solely on retrospective items, though the latter may still be necessary in certain cases. Advances in biomarker identification, including polymerase chain reaction (PCR) and gene expression (mRNA) profiling, offer diagnostic advantages over current methods, enabling early detection within 4 to 6 h of intensive care unit admission. Mass spectrometry also shows promise for the rapid determination of bacteria, yeast, and fungi based on bacteria protein profiles. Source control remains crucial, and the use of antibacterial topical agents has significantly improved the survival rates of severely burned patients. However, antibiotic selection must be made judiciously to avoid resistance. Despite these advancements, significant progress is still needed to improve the rapid identification, actual presence, prevention, and therapy of infections to reduce the incidence of sepsis and septic shock in this patient subgroup.
