Objective To investigate the effects of fast-track anesthesia on hemodynamics, awakening quality, and neurological function in patients undergoing cardiac surgery.

Methods A total of 130 patients undergoing cardiac surgery were selected and were randomly divided into control group (n=65) and study group (n=65). The clinical data of the patients were collected, and the hemodynamic parameters, awakening quality, neurological function, and incidence of postoperative complications were compared between the two groups.

Results The study group had lower dosages of fentanyl citrate injection and rocuronium bromide compared with the control group (P < 0.05). After anesthesia induction and tracheal intubation, the heart rate (HR), mean arterial pressure (MAP), cardiac output (CO), cardiac index (CI), and bispectral index (BIS) were changed compared with before anesthesia induction in both groups, but the degree of change in the study group was less than that in the control group (P < 0.05). The study group had shorter postoperative recovery time to breathe, awakening time, extubation time, ICU stay time, and postoperative hospital stay compared with the control group, the incidence of restlessness after extubation was lower in the study group than in the control group (P < 0.05). The study group had lower levels of neuron-specific enolase (NSE) and β-amyloid protein (Aβ) at 180 min after arterial cannulation compared with the control group (P < 0.05). The total incidence of postoperative complications was 3.08% in the study group, which was lower than 16.92% in the control group (P < 0.05).

Conclusion Fast-track anesthesia can effectively stabilize hemodynamics in patients undergoing cardiac surgery, improve awakening quality and neurological function, and reduce the incidence of postoperative complications.
