Background: Early postoperative neurocognitive disorders (ePND), include both emergence delirium, which is defined as very early onset postoperative delirium, and emergence agitation, defined as motor arousal. Although research on anesthesia emergence is limited, ePND are likely associated with unfavorable outcomes. This meta-analysis assessed the effect of ePND on clinically relevant outcomes.Methods: A systematic search of studies published between 2002 and 2022 on MEDLINE, PubMed, Google Scholar, and the Cochrane Library was performed. Studies that included adults with emergence agitation and/or delirium and reported at least one of the following outcomes: mortality, postoperative delirium, length of post-anesthesia care unit stay, or length of hospital stay were included. The internal validity, risk of bias, and certainty of the evidence were assessed.Results: A total of 16,028 patients from 21 prospective observational studies and one case-control retrospective study were included in this meta-analysis. The occurrence rate of ePND was 13% (data excluding the case-control study). The mortality rate was 2.4% in patients with ePND vs. 1.2% in the normal emergence group (risk ratio [RR]: 2.6, P = 0.01, very low quality of evidence). Postoperative delirium occurred in 29% of patients with ePND and 4.5% of patients with normal emergence (RR: 9.5, P < 0.001, I2 = 93%). Patients with ePND had a prolonged length of post-anesthesia care unit stay (P = 0.004) and length of hospital stay (P < 0.001).Conclusions: This meta-analysis suggests that ePND are associated with twice the risk of mortality and a 9-fold increased risk of postoperative delirium.

<P>Abstract. We conducted long-term network observations using standardized Multi-Axis Differential optical absorption spectroscopy (MAX-DOAS) instruments in Russia and ASia (MADRAS) from 2007 onwards and made the first synthetic data analysis. At seven locations (Cape Hedo, Fukue and Yokosuka in Japan, Hefei in China, Gwangju in Korea, and Tomsk and Zvenigorod in Russia) with different levels of pollution, we obtained 80 927 retrievals of tropospheric NO2 vertical column density (TropoNO2VCD) and aerosol optical depth (AOD). In the technique, the optimal estimation of the TropoNO2VCD and its profile was performed using aerosol information derived from O4 absorbances simultaneously observed at 460-490 nm. This large data set was used to analyze NO2 climatology systematically, including temporal variations from the seasonal to the diurnal scale. The results were compared with Ozone Monitoring Instrument (OMI) satellite observations and global model simulations. Two NO2 retrievals of OMI satellite data (NASA ver. 2.1 and Dutch OMI NO2 (DOMINO) ver. 2.0) generally showed close correlations with those derived from MAX-DOAS observations, but had low biases of up to ~50%. The bias was distinct when NO2 was abundantly present near the surface and when the AOD was high, suggesting a possibility of incomplete accounting of NO2 near the surface under relatively high aerosol conditions for the satellite observations. Except for constant biases, the satellite observations showed nearly perfect seasonal agreement with MAX-DOAS observations, suggesting that the analysis of seasonal features of the satellite data were robust. Weekend reduction in the TropoNO2VCD found at Yokosuka and Gwangju was absent at Hefei, implying that the major sources had different weekly variation patterns. While the TropoNO2VCD generally decreased during the midday hours, it increased exceptionally at urban/suburban locations (Yokosuka, Gwangju, and Hefei) during winter. A global chemical transport model, MIROC-ESM-CHEM (Model for Interdisciplinary Research on Climate-Earth System Model-Chemistry), was validated for the first time with respect to background NO2 column densities during summer at Cape Hedo and Fukue in the clean marine atmosphere. </P>
