Abstract:
Objective:To evaluate the effect of s-ketamine on perioperative myocardial injury in patients undergoing liver transplantation.Methods:This was a prospective randomized controlled study. Sixty American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ patients, aged 18-64 yr, with New York Heart Association classⅠ-Ⅲ, undergoing elective liver transplantation with general anesthesia in our hospital from May to October 2023, were divided into 2 groups ( n=30 each) using a random number table method: s-ketamine group (group S) and control group (group C). In group S, s-ketamine was intravenously injected at a dose of 0.5 mg/kg after induction of anesthesia, followed by an infusion of 0.5 mg·kg -1·h -1 until the end of surgery. The equal volume of normal saline was given instead in group C. Central venous blood samples were collected after induction of anesthesia (T 0), at 30 min of anhepatic phase (T 1), 30 min of neopepatic phase (T 2), abdominal closure (T 3), 24 h after operation (T 4) and 72 h after operation (T 5) for determination of the concentrations of serum high-sensitivity cardiac troponin I, creatine kinase-MB isoenzyme, N-terminal pro-B-type natriuretic peptide, tumor necrosis factor-α, interleukin-6 (IL-6), IL-10 and high-mobility group protein B1 by enzyme-linked immunosorbent assay. The occurrence of adverse cardiac events during surgery and within 24 h after surgery, postoperative mechanical ventilation time, time of intensive care unit stay, and postoperative length of hospital stay were recorded. Results:Compared with group C, the concentrations of serum high-sensitivity cardiac troponin I, creatine kinase-MB isoenzyme, N-terminal pro-B-type natriuretic peptide, tumor necrosis factor-α and IL-6 at T 2-5 and high-mobility group protein B1 at T 2-4 were significantly decreased, the concentrations of serum IL-10 were increased at T 2-5, the incidence of myocardial ischemia was decreased, the mechanical ventilation time was shortened ( P<0.05), and no significant change was found in the time of intensive care unit stay and postoperative length of hospital stay in S group ( P>0.05). Conclusions:Intraoperative usage of s-ketamine can inhibit the inflammatory responses and reduce perioperative myocardial injury in the patients undergoing liver transplantation.
