AbstractTerlipressin (TP), an analog of arginine vasopressin, was reported beneficial in sepsis patients when combined use with norepinephrine (NE), but the undetermined action, mechanism, and safety limited it to become the first-line vasopressor for sepsis patients. With 32 septic shock patients, we investigated the effects of a small dose of TP (1.3 μg/kg/h) on hemodynamic, tissue blood flow, vital organ function, acid-base balance, and coagulation function to systemically know the beneficial effect and side effects of TP on septic shock. The results showed that as compared with the single use of NE group (17 patients), a small dose of TP (1.3 μg/kg/h) in combination with NE continuous infusion, except for decreasing the mortality and NE requirement, could better improve and stabilize the hemodynamics, improve the tissue blood flow, increase the blood oxygen saturation and urine volume, and decrease the lactate level and complication rate (47% versus 82.3% in NE group). Meanwhile, TP + NE did not induce blood bilirubin increase and platelet count decrease and hyponatremia that vasopressin has. The results show that low dose of TP continuous infusion can help NE achieve the good resuscitation effect by improving tissue blood flow, stabilizing hemodynamics, and protecting organ function in septic shock patients while did not induce the side effects that high dose or bonus of TP or vasopressin induced. Low dose of TP may be recommended as the first-line vasopressor for refractory hypotension after severe sepsis or septic shock. Copyright © 2016 Elsevier Inc. All rights reserved.
