Abstract:Objective To observe the effect of sufentanil-based fast-track cardiac anesthesia on Narcotrend index and hemodynamics in children with congenital heart disease (CHD).Methods A total of 102 children who underwent surgery for CHD in the hospital between June 2022 and June 2024 were selected with retrospectively analyzing their data, and divided into the control group (conventional anesthesia) and the observation group (sufentanil-based fast-track cardiac anesthesia) according to different anesthesia methods, with 51 cases in each group. Narcotrend index, heart rate (HR), mean arterial pressure (MAP) and blood oxygen saturation (SpO2) before surgery (T0), after intubation (T1), 1 h after the beginning of surgery (T2) and at the end of surgery (T3) were compared between groups. The incidence of adverse events and rehabilitation process were observed.Results The differences were statistically significant when comparing Narcotrend index, HR, and MAP at different time points (P < 0.05, respectively), and the difference was not statistically significant when comparing SpO2 at different time points (P > 0.05). The differences in Narcotrend index, HR, and MAP between the two groups were statistically significant (P < 0.05), and the difference in SpO2 between the two groups was not statistically significant (P > 0.05). Comparing the trends of Narcotrend index, HR, and MAP in the two groups, the difference was statistically significant (P < 0.05), and comparing the trends of SpO2 in the two groups, the difference was not statistically significant (P > 0.05); the incidence rate of total adverse reactions in the observation group was lower than that in the control group (P < 0.05); autonomous breathing time, extubation time, resumption of feeding time, ICU stay, and hospitalisation time in the observation group were shorter than those in the control group (P < 0.05).Conclusion Applying sufentanil-based fast-track cardiac anesthesia to children undergoing surgery for CHD can quickly achieve deep sedation and maintain hemodynamic stability, with few adverse events. It is conducive to postoperative recovery of the children.
