        Combined cerebral and somatic near-infrared spectroscopy oximetry monitoring during liver surgery: an observational and non-interventional study

        Collin Yves,Hu Tina,Denault André,Fortier Annik,Beaubien-Souligny William,Lapointe Réal,Vandenbroucke-Menu Franck 대한마취통증의학회 2022 Korean Journal of Anesthesiology Vol.75 No.5

        Background: Cerebral oximetry using near-infrared spectroscopy (NIRS) is used for monitoring cerebral oxygen saturation during cardiac surgery and is correlated with clinical outcomes. Our goal was to explore cerebral and somatic NIRS in liver resections as a predictor of post-operative complications. Methods: Prospective observational and non-interventional study from a tertiary care university hospital including adult patients undergoing liver resection monitored using NIRS at four sites before and during surgery. Those sites were: frontotemporal left and right zones, right thigh, and right arm. Anesthesiologists and surgeons were blinded to oximetry values. Correlations were assessed between baseline oximetry values and cerebro-somatic desaturation load (threshold of 80% from baseline) values with peri-operative events and complications. Results: Ninety patients were distributed equally among gender with a mean age of 59.7 ± 13.1 years. Lower baseline cerebral and/or somatic values were associated with increased risk of delirium, respiratory failure, surgical and renal complications, blood transfusions, and length of stay in the intensive care unit and in the hospital (P < 0.05). The severity of somatic desaturation below 80% was the only parameter associated with blood losses (P = 0.030) and length of hospital stay (P = 0.047). Conclusions: Cerebral and somatic desaturation does occur in liver resection and can be used simultaneously during liver surgery. Both baseline cerebral and somatic NIRS values are correlated with complications and outcomes. However, thigh desaturation appears more sensitive than cerebral NIRS values in predicting some of these complications.

        Does Foreign Bank Entry Make Chinese Banks Stronger?

        Yingkai Yin,Yahua Zhang,Xiaotian Tina Zhang,Fang Hu 연세대학교 동서문제연구원 2015 Global economic review Vol.44 No.3

        China has encouraged its domestic banks to introduce foreign investment since the early 2000s. In the meantime, China has gradually fulfilled its World Trade Organisation (WTO) accession commitment to give foreign banks the same treatment as their Chinese counterparts in the last decade. This research has examined the effects of the two modes of foreign bank entry, namely, minority ownership participation, and setting up branches and subsidiaries, on the performance of Chinese banks. Our results suggest that there is no systematically significant impact of the minority ownership participation on the performance indicators of Chinese banks. However, it appears that the physical presence of foreign banks has been a significant driver for domestic banks to improve profitability and efficiency. Opening the country to foreign banks appears to have made Chinese banks stronger and more competitive.
