Objective To compare the effect of different sevoflurane induction methods on hemodynamics and immune function in elderly patients with tumor. Methods One hundred and sixty elderly patients with tumor underwent general anesthesia were enrolled, the patients were divided into observation group and control group according to the anesthesia method with 80 cases each. The observation group was received induction method of initial concentration of 2%sevoflurane and increased by 1% per 3 times breathing and then to a final concentration of 4%- 5%. The control group was received 5% sevoflurane induction concentration. The anesthesia induction time, intubation time, recovery time and untoward reaction were recorded. The changes of heart rate, mean arterial pressure (MAP), oxygen saturation of pulse (SpO2), bispectral index (BIS) and CD3+, CD4+, CD8+, CD4+/CD8+were observed. Results There were no statistical differences in BIS, heart rate, SpO2, CD3 +, CD8 + and incidence of untoward reaction between 2 groups (P>0.05). The MAP at immediate intubation in observation group was significantly higher than that in control group:(69.38 ± 10.42) mmHg (1 mmHg=0.133 kPa) vs. (58.52 ± 6.12) mmHg, but the MAP at after intubation was significantly lower than that in control group: (77.12 ± 11.31) mmHg vs. (90.13 ± 9.24) mmHg, there were statistical differences (P<0.05). The anesthesia induction time and intubation time in observation group were significantly longer than those in control group:(110.1 ± 14.2) s vs. (101.4 ± 15.8) s and (341.2 ± 57.3) s vs. (310.4 ± 60.8) s, but the recovery time was significantly shorter than that in control group: (271.2 ± 31.3) s vs. (321.8 ± 41.5) s, there were statistical differences (P<0.05). The CD4+and CD4+/CD8+at end of surgery and 1 d after surgery in observation group were significantly higher than those in control group, CD4+:0.241 ± 0.027 vs. 0.182 ± 0.034 and 0.332 ± 0.039 vs. 0.284 ± 0.042, CD4+/CD8+: 0.84 ± 0.12 vs. 0.69 ± 0.13 and 1.09 ± 0.52 vs. 0.93 ± 0.43, there were statistical differences (P<0.05). Conclusions Induction method of gradually increasing concentration of sevoflurane enables the hemodynamics of elderly tumor patients more stable. In addition, this method can reduce the inhibitory effect on T lymphocytes to some extent.

Improving the quality of newborns is a health development strategy, which has attracted global attention. Adverse pregnancy outcomes, including preterm birth, low birth weight and small for gestational age, are major causes of perinatal mortality and disability. Based on review of international and national publications pertaining to associations between stressful life events during pregnancy and adverse pregnancy outcomes from 2007 to 2023, this review summarizes the correlation between stressful life events during pregnancy and adverse pregnancy outcomes, including preterm birth, low birth weight and small for gestational age, and describes the underlying biological mechanisms. Previous studies have demonstrated the associations between maternal stressful life events during pregnancy and adverse pregnancy outcomes, and the underlying mechanisms mainly include neuroendocrine regulation, inflammation and microbiota pathways; however, the exact mechanisms remain unclear until now. Further studies to identify the critical window period for the association between stressful life events and adverse pregnancy outcomes, and unravel the pathogenesis of adverse pregnancy outcomes are warranted, so as to provide insights into reduction of adverse pregnancy outcomes.
