Objective:To explore the application effect of thoracic paravertebral nerve block combined with non-tracheal intubation anesthesia preserving spontaneous respiration in thoracoscopic surgery.Methods:Sixty patients who underwent thoracoscopic surgery in thoracic surgery were divided into two groups, 30 cases in each group. The control group received tracheal intubation general anesthesia, while the observation group received thoracic paravertebral nerve block combined with non-tracheal intubation anesthesia retaining spontaneous breathing. The anesthesia effect, vital signs index, arterial oxygen index, incidence rate of adverse reactions, anesthesia time, operation time, postoperative anesthesia recovery and cognitive function scores of the two groups were compared.Results:The excellent and good rate of anesthesia in the observation group was slightly better than that in the control group(96.67% vs. 93.30%, P>0.05). The systolic blood pressure, diastolic blood pressure, and heart rate of the two groups had no significant changes before and after anesthesia(P>0.05). PaO2, SpO2 and PaCO2 of the two groups had no significant changes during the perioperative period(P>0.05), and there was no difference in PaO2, SpO2, PaCO2 between the two groups after surgery(P>0.05). The incidence of adverse reactions was 0% in the observation group, which was lower than 13.33% in the control group(P<0.05). The observation group's anesthesia time, the postoperative spontaneous breathing recovery time, the time to open the eyes after the operation, and the orientation recovery time were shorter than those of the control group(P<0.05). The MMSE and MoCA scores of the two groups at 48 hours after surgery were significantly lower than those before surgery(P<0.05), and the scores of the observation group were higher than those of the control group(P<0.05).Conclusion:Thoracoscopic surgery with thoracic paravertebral nerve block combined with non-tracheal intubation anesthesia preserving spontaneous breathing can reduce adverse reactions, shorten operation time, accelerate postoperative recovery and reduce postoperative cognitive dysfunction on the premise of ensuring anesthesia effect, maintaining vital signs and stable arterial oxygen status. |
