摘要：The aim of this work was to investigate preventive effect of dexmedetomidine combined with sevoflurane on neurological disorders in liver cancer patients during postoperative recovery under the ultrasound image restoration (UIR) algorithm. A blind deconvolution medical UIR algorithm was established in this study. The patients anesthetized with sevoflurane for liver cancer surgery were rolled into an experimental group (group A) (dexmedetomidine treatment before surgery) and a control group (group B) (normal saline treatment before surgery). They were monitored routinely before, during, and after surgery, and immune and liver functions of patients were observed before and after surgery. Besides, their cognitive function and adverse reactions were assessed after surgery. Results showed that patients from group A had smaller fluctuation in average arterial blood pressure and heart rate, but their bispectral index (BIS) increased obviously after surgery in contrast to those of group B ( P < 0.05 ). Moreover, changes of immune and liver functions in patients from group A decreased sharply compared with group B ( P < 0.05 ). The postoperative minimental state examination (MoCA) score of patients from group A was 27.51 ± 2.02, while the score of group B was 25.79 ± 2.35. The postoperative (MoCA) score of group A was markedly higher than the score of group B, and the difference was statistically obvious ( P < 0.05 ). Besides, the incidence of postoperative cognitive dysfunction (POCD) in patients from group A and B was 12.91% and 32.26% in turn. The incidence of POCD in patients from group A was sharply lower than the incidence of group B ( P < 0.05 ). In addition, the total incidence of adverse reactions in patients from group A was 6.45%, which was significantly lower than the 22.58% of group B, and the difference was statistically substantial ( P < 0.05 ). In summary, dexmedetomidine combined with sevoflurane could effectively reduce POCD and promote systemic circulation recovery, which had clinical application value.
