Abstract:
Objective:To investigate the sedative effect after congenital heart disease surgery in children under the bi-spectral index monitoring(BIS).Methods:A prospective cohort study was performed, we selected 264 children with congenital heart disease who were admitted to the cardiac intensive care unit at Shanghai Children′s Medical Center from September 2018 to August 2019, 126 cases in the intervention group, and 138 cases in the control group.The control group used Ramsay sedation score to evaluate the sedative effect, meanwhile the intervention group was evaluated by Ramsay sedation score and BIS.The incidence of adverse events related to extubation performed within 8 hours after congenital heart disease surgery, and the length of stay in ICU between two groups were compared.The average mechanical ventilation time of the patients whose mechanical ventilation time was more than 8 hours in two groups was compared.The use of sedative drugs midazolam and morphine in children with mechanical ventilation time for more than 24 hours and liver damage, and the incidence of respiratory depression during ventilator withdrawal were analyzed.Results:In children with early extubation, there were 62 cases in the intervention group and 70 cases in the control group.Compared with the control group, the intervention group had a low incidence of extubation-related adverse events (including unplanned extubation, dysphoria after sputum aspiration, and inhalation inhibition after extubation). The average mechanical ventilation time in the intervention group[(8.18±1.95)h] was less than that in the control group[(9.53±1.37)h, P<0.05] of the patients whose mechanical ventilation time was more than 8 hours but less than 24 hours.In children with mechanical ventilation time more than 24 hours, 28 cases were in the intervention group and 35 cases in the control group.The average doses of midazolam and morphine in the intervention group[(1.82±0.40)μg/(kg·min), (8.64±3.03)μg/(kg·h)] were less than those in the control group[(2.73±0.79) μg/(kg·min), (14.32±5.01)μg/(kg·h), all P<0.05]. Among the 28 children in the intervention group with mechanical ventilation time more than 24 hours, 13 cases had liver damage, and 15 cases of the 35 children in the control group had liver damage.The average doses of midazolam and morphine in the intervention group[(1.42±0.51)μg/(kg·min), (6.88±2.17)μg/(kg·h)] were lower than those in the control group[(2.25±0.62)μg/(kg·min), (11.88±3.56)μg/(kg·h), all P<0.05]. The incidence of inhalation inhibition in the intervention group was lower than that in the control group ( χ2=48.303, P<0.05). Conclusion:The sedation after congenital heart disease surgery in children under the BIS is effective.
