Total intravenous anesthesia for liver resections: anesthetic implications and safety

Selene Yan Ling Tan, Nian Chih Hwang

Korean J Anesthesiol. 2022;75(5):363-370.

Inhalational anesthetics have been the default agents for general anesthesia maintenance for several decades. However, with advances in total intravenous anesthesia (TIVA) and a growing body of evidence on the potential benefits of TIVA, anesthesiologists need to question this paradigm. Some of the benefits of propofol-based TIVA, such as its antiemetic properties and patients’ smooth emergence, are widely acknowledged. A growing body of evidence suggests that TIVA may potentially benefit the immune system and cancer outcomes. From an existential health perspective, there is evidence that inhalational agents have a materially higher global warming potential than propofol-based TIVA. Despite the compelling potential benefits of propofol-based TIVA,...

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

Yves Collin, Tina Hu, André Denault, Annik Fortier, William Beaubien-Souligny, et al.

Korean J Anesthesiol. 2022;75(5):371-390.

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....

Propofol abuse among healthcare workers: an analysis of criminal cases using the database of the Supreme Court of South Korea’s judgments

Hye-Yeon Cho, Yoonbin Hwang, SuHwan Shin, Susie Yoon, Ho-Jin Lee

Korean J Anesthesiol. 2022;75(5):391-396.

Background: Due to its abuse potential, propofol has been classified as a controlled substance since February 2011 in South Korea. Healthcare workers are exposed to propofol abuse considering their easy access to this substance in hospitals. Therefore, we aimed to investigate propofol abuse among healthcare workers through the database of the Supreme Court in South Korea. Methods: We retrospectively analyzed adjudicated criminal cases related to propofol abuse among healthcare workers from January 1, 2013, to December 31, 2020, using the database of the Supreme Court of South Korea’s judgments. We collected...

Association of HLA-DPA1 polymorphism with prolonged mechanical ventilation in patients undergoing liver transplantation

Eun Jung Kim, Min-Soo Kim, Myoung Soo Kim, Junhyun Nam, Seung Ho Choi

Korean J Anesthesiol. 2022;75(5):397-406.

Background: Prolonged mechanical ventilation (PMV) is a common complication after liver transplantation surgery. However, owing to the clinical and economic benefits of early extubation, many efforts have been used to assess the clinical predictors for PMV. The aim of our study was to explore the impact of perioperative risk factors, including candidate gene polymorphisms, for PMV in patients undergoing liver transplantation. Methods: One hundred forty patients who underwent liver transplantation surgery were enrolled. The duration of mechanical ventilation after surgery was examined, along with the length of intensive care unit and hospital stay, and 30-day mortality. Patient-related clinical factors and single nucleotide polymorphisms of candidate genes were assessed with regard to...

Epidemiologic study of epidural analgesia for lung cancer surgery from 2011 to 2018 in South Korea: a National Health Insurance Database cohort study

Tak Kyu Oh, In-Ae Song

Korean J Anesthesiol. 2022;75(5):407-415.

Background: Epidural analgesia is commonly used for pain control during lung cancer surgery. However, the clinical trends in epidural analgesia, associated factors, and their association with clinical outcomes remain controversial. Therefore, we aimed to investigate the trends, associated factors, and their association with the clinical outcomes of epidural analgesia for lung cancer surgery. Methods: The National Health Insurance Database was used as the data source in a nationwide cohort study. All adult patients who underwent lung cancer surgery between 2011 and 2018 were included. Results: A total of 60,031 adult patients...

Prognostic value of left ventricular apical four-chamber longitudinal strain after heart valve surgery in real-world practice

Jae-Sik Nam, Ji-Hyun Chin, Hyun-Uk Kang, Juyoun Kim, Kyoung-Woon Joung, et al.

Korean J Anesthesiol. 2022;75(5):416-426.

Background: Left ventricular longitudinal strain is an emerging marker of ventricular systolic function. However, the prognostic value of apical four-chamber longitudinal strain after heart valve surgery in real-world clinical practice is uncertain. The authors investigated whether left ventricular apical four-chamber longitudinal strain measured in real-world practice is helpful for predicting postoperative outcomes in patients undergoing heart valve surgery. Methods: This observational cohort study was conducted in patients who underwent heart valve surgery between January 2014 and December 2018 at a tertiary hospital in South Korea. The exposure of interest was preoperative...

The state of anesthesia in South Korea: a national survey of the status of anesthetic service activity in 2014–2016

Eun-Su Choi, Hee-Won Jung, Woon Young Kim, Jae Hwan Kim, Yoon-Sook Lee

Korean J Anesthesiol. 2022;75(5):427-436.

Background: Because the quality of anesthesia affects the surgical outcome, the aim of this study was to investigate the current status of anesthetic services performed by anesthesiologists and non-anesthesiologists in South Korea from 2014 to 2016 and to compare the results with data from 2011 to 2013. Methods: The claimed anesthesia services at medical institutions with employed anesthesiologists and the claims for an invitation fee for an anesthesiologist at medical institutions without employed anesthesiologists were regarded as anesthetic services performed by an anesthesiologist. From 2014 to 2016, the employment of anesthesiologists...

Use of a human patient simulator for apnea studies: a preliminary in vitro trial

Debendra Kumar Tripathy, Mridul Dhar, Bharat Bhushan Bhardwaj, K Hemanthkumar, Praveen Talawar, et al.

Korean J Anesthesiol. 2022;75(5):437-444.

Background: Modern human patient simulators (HPSs) could be used for researching critical scenarios such as apnea oxygenation. We aimed to study the use of a high-fidelity HPS to assess prolonged apnea using various oxygenation strategies with a simple high-flow nasal cannula (15 L/min). Methods: An experimental simulation study using an HPS (CAE Healthcare™) was conducted after obtaining approval from the Institutional Review Board. The HPS responded according to real-time physiologically modeled responses to external gases, such as oxygen (O2). Apnea experiments were performed with different physiological settings, such as shunt fraction (5%) and O2 consumption (250, 500, and 750 ml/min). The following four apnea experiments were conducted: no oxygenation (NO), apnea...
