Abstract:
Objective:To evaluate the myocardial protective effect of goal-directed circulation management guided by cardiac index (CI) monitored by pressure recording analytical method (PRAM) in infants undergoing pediatric liver transplantation.Methods:A total of 120 pediatric patients, aged 5-15 months, weighing 5.5-10.0 kg, scheduled for elective living donor liver transplantation (all diagnosed with congenital biliary atresia) were selected and divided into 2 groups ( n=60 each) using a random number table method: routine group (group R) and goal-directed management guided by CI group (group CI-G). Patients in group R received routine hemodynamic monitoring according to central venous pressure (CVP), continuous invasive arterial pressure, blood gas analysis and other monitoring methods to guide intraoperative circulation management.Patients in CI-G group received intraoperative hemodynamic monitoring through radial artery using PRAM/Mostcare, and related treatments were guided by PRAM hemodynamic monitoring indicators.The intraoperative volume of fluid intake, highest and lowest values of parameters of hemodynamics such as heart rate (HR), mean arterial pressure (MAP) and CVP, the maximum fluctuations (△ RHR, △ RMAP and △ RCVP) and the development of reperfusion syndrome within 5 min of reperfusion were recorded.At the beginning of anesthesia (T 0), at 5 min before reperfusion (T 1), at 30 min of neohepatic phase (T 2), at 3 h of neohepatic phase (T 3) and at 12 h after operation (T 4), concentrations of serum cardiac troponin I (cTnI), N-terminal plasma brain natriuretic peptide precursor (NT-pro-BNP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and high mobility group protein B1 (HMGB1) were determined.Mechanical ventilation time, duration of intensive care unit (ICU) stay, the development of heart failure and pulmonary infection, length of hospital stay were recorded. Results:Compared with group R, the intraoperative volume of fluid intake, highest value of CVP, △ RHR, △ RMAP and the incidence of reperfusion syndrome were significantly decreased, lowest value of MAP was increased, concentrations of serum cTnI, NT-pro-BNP, IL-6, TNF-α and HMGB1 was decreased, mechanical ventilation time and duration of ICU were shortened, and the incidence of heart failure during ICU stay were decreased in group CI-G( P<0.05). Conclusion:The goal-directed circulation management guided by CI monitored by PRAM can accurately guide the use of volume and vasoactive drugs, stabilize circulation, which can produce myocardial protective effect to some extent in infants undergoing pediatric liver transplantation.
