Objective To evaluate the correlation of Fast-track extubation ultrasound score (FTEUS) and clinical multi-organ information indicators in post-cardiac surgery patients.
Methods prospectively recruit post-cardiac surgery patients who were about to extubating from Febuary 2019 to September 2019. A fast-track extubation ultrasound score protocol (FTE-USP) was developed on the basis of the conventional fast-track extubation standard precisely and individualized. Cardiac, pulmonary and inferior vena cava ultrasound examinations were performed by specially trained observers, video data were saved, FTE-USP was used for scoring, Kendall consistency coefficient was used to meature the interobserver consistency. The correlation between the FTEUS and the patients' clinical indicators was evaluated.
Results A total of 207 patients were recruited in the study, including 89 males and 118 females, aged (54.63±11.80) years. The FTEUS was performed at bedside with a mean time of (8.23±2.08) min, Kendall consistency coefficient is 0.941. With the increase of the total score of FTEUS, the incidence of clinical adverse events increased (especially the arrhythmia), and there were significant changes in liver, kidney, heart, lung and other organ function indicators, among which serum creatinine level, serum cystatin C level, serum NT-pro-brain natriuretic peptide, length of stay in intensive care unit, non-invasive mechanical ventilation time after extubation, and incidence of arrhythmia were positively correlated with FTEUS (P < 0.05).With FTEUS increased to 5 points, the incidence of arrhythmia (14/24, 58.3%), cardiopulmonary resuscitation (2/24, 8.3%) and weaning failure (2/24, 8.3%) increased.
Conclusion FTE-USP integrates multi-organ informations, can be performed quickly at the bedside and alerts adverse events. It has the potential to be applied to assist clinical decision-making in post-cardiac surgery patients before extubation.
