It will also evaluate the safety of dexmedetomidine in this population.\n\nThe main questions it aims to answer are:\n\nDoes early dexmedetomidine improve sympathetic nervous system activity, as measured by heart rate variability (HRV) and blood pressure variability (BPV)?\n\nDoes dexmedetomidine reduce endogenous catecholamine levels and vasopressor requirements?\n\nDoes early autonomic modulation improve organ function and survival outcomes in septic shock? Researchers will compare dexmedetomidine to a placebo (normal saline) to determine whether dexmedetomidine improves hemodynamic stability and prognosis in patients with septic shock.\n\nParticipants will:\n\nBe randomly assigned to receive dexmedetomidine (0.5 μg\u002Fkg\u002Fh) or placebo by continuous intravenous infusion for 48 hours\n\nUndergo continuous ECG and invasive blood pressure monitoring\n\nHave blood samples collected at predefined time points to measure inflammatory markers and endogenous catecholamine levels\n\nBe assessed for organ function, vasopressor use, and perfusion parameters during the first 48 hours\n\nBe followed up for 28-day and 90-day survival outcomes",[57,58],"Sepsis","Septic Shock",[15,60,58],"Sympathetic Nervous System","NOT_YET_RECRUITING","2026-03-10",{"date":64,"type":65},"2026-03-13","ACTUAL",{"date":67,"type":51},"2026-03-01",{"date":69,"type":51},"2028-03-01",{"name":5,"class":6}]
