Abstract:
Objective:To investigate the effect of regional cerebral oxygen saturation (rSO 2) combined with neurophysiological blood pressure monitoring on brain protection and myocardial protection during carotid endarterectomy (CEA) in patients with carotid stenosis and coronary heart disease. Methods:One hundred patients with carotid artery stenosis complicated with coronary heart disease treated in Jinhua Central Hospital from June 2021 to June 2022 were randomly divided into control group and experimental group. All patients were scheduled to undergo CEA. Fifty patients in the control group were administered with empirically increasing basic blood pressure by 20% - 30%, and 50 patients in the experimental group were administered with blood pressure under the guidance of rSO 2 combined with motor evoked potentials (MEPs) and somatosensory evoked potentials (EPS). The neurological function indexes of the two groups [neuron specific enolase (NSE), central nerve specific protein (S100-β)], myocardial function indicators [cardiac troponin I (cTnI), B-type natriuretic peptide (BNP)], clinical indicators (eye opening time, extubation time, recovery room stay time, hospital stay) and the incidence of postoperative complications [delirium (POD), cognitive dysfunction (POCD), neurological impairment] were compard between the two groups. Results:Two sets of postoperative NSE and S100-β both increased ( P<0.05), but NSE and S100 in the experimental group after surgery were lower than those in the control group: (0.82 ± 0.14) μg/L vs. (1.18 ± 0.28) μg/L, (290.13 ± 27.25) mg/L vs. (301.98 ± 28.56) mg/L, the differences were statistically significant ( P<0.05). After surgery, cTnI and BNP increased in both groups ( P<0.05), but the cTnI and BNP in the experimental group were lower than those in the control group: (2.87 ± 0.74)] μg/L vs. (3.36 ± 0.83) μg/L, (3.01 ± 0.85) μg/L vs. (3.89 ± 0.92) μg/L, the differences were statistically significant ( P<0.05). The opening time, extubation time, recovery room stay time, and hospitalization time in the experimental group were shorter than those in the control group: (16.79 ± 3.15) min vs. (20.55 ± 3.83) min, (29.38 ± 4.66) min vs. (40.14 ± 4.57) min, (66.82 ± 15.80) min vs. (89.35 ± 24.78) min, (11.24 ± 4.89) d vs. (14.56 ± 6.74) d, there were statistical differences ( P<0.05). The incidence of postoperative complications in the experimental group was lower than that in the control group: 12.00% (6/50) vs. 28.00% (14/50), there was statistical difference ( P<0.05). Conclusions:The application of rSO 2 combined with neurophysiological blood pressure monitoring in CEA of patients with carotid artery stenosis and coronary heart disease has a good effect, which has brain protection and myocardial protection, can shorten the recovery time of anesthesia and hospitalization time, and reduce the incidence of postoperative complications.
