Different perspectives for monitoring nociception during general anesthesia
Pablo Martinez-Vazquez, Erik Weber Jensen
Korean J Anesthesiol. 2022;75(2):112-123.

Safe anesthesia is achieved using objective methods that estimate the patient’s state during different phases of surgery. A patient’s state under anesthesia is characterized by three major aspects, which are linked to the main effects produced by each of the families of anesthetic agents administered: hypnosis, analgesia, and muscular relaxation. While quantification techniques designed to assess muscular relaxation under neuromuscular blocking agents have a relatively long history with a high degree of standardization and understanding (e.g., the train-of-four), the knowledge and techniques used to the depth of hypnosis assessment suffer from a lesser degree in both standardization and interpretation due to brain complexity. The problem of standardization and interpretation in...

How general anesthetics work: from the perspective of reorganized connections within the brain
Teo Jeon Shin, Pil-Jong Kim, Bernard Choi
Korean J Anesthesiol. 2022;75(2):124-138.

General anesthesia is critical for various procedures and surgeries. Despite the widespread use of anesthetics, their precise mechanisms remain poorly understood. Anesthetics inevitably act on the brain, primarily through the modulation of target receptors. Even if the action is specific to an individual neuron, however, long-range effects can occur due to the tremendous interconnectedness of neuronal activity. The strength of this connectivity can be understood using mathematical models that allow for the study of neuronal connectivity dynamics. These models also allow researchers to develop hypotheses on the candidate mechanisms of action of different types of anesthesia. This review highlights the theoretical background associated with the study of the mechanisms of...

The principles of presenting statistical results using figures
Jae Hong Park, Dong Kyu Lee, Hyun Kang, Jong Hae Kim, Francis Sahngun Nahm, et al.
Korean J Anesthesiol. 2022;75(2):139-150.

Tables and figures are commonly adopted methods for presenting specific data or statistical analysis results. Figures can be used to display characteristics and distributions of data, allowing for intuitive understanding through visualization and thus making it easier to interpret the statistical results. To maximize the positive aspects of figure presentation and increase the accuracy of the content, in this article, the authors will describe how to choose an appropriate figure type and the necessary components to include. Additionally, this article includes examples of figures that are commonly used in research and their essential components using virtual data.

Noninvasive cardiac output measurements are inaccurate in patients with severe aortic valve stenosis undergoing transcatheter aortic valve implantation
Musashi Yahagi, Kyuma Omi, Takuma Maeda
Korean J Anesthesiol. 2022;75(2):151-159.

Background: Noninvasive cardiac output (CO) measured using ClearSight™ eliminates the need for intra-arterial catheter insertion. The purpose of this study was to examine the accuracy of non-invasive CO measurement in patients with severe aortic valve stenosis (AS). Methods: Twenty-eight patients undergoing elective transcatheter aortic valve implantation were prospectively enrolled in this study. The CO was simultaneously measured twice before and twice after valve deployment (total of four times) per patient, and the CO was compared between the ClearSight (COClearSight) system and the pulmonary artery catheter (PAC)...

Effect of chemotherapy on effect-site concentration of propofol for loss of consciousness in patients with colorectal cancer
Seunghee Ki, Yongwon Cho, Youngkyung Choi, Sehun Lim, Myounghun Kim, et al.
Korean J Anesthesiol. 2022;75(2):160-167.

Background: The depth of anesthesia is an essential factor in surgical prognosis. The neurotoxic effect of chemotherapeutic drugs affects the sensitivity to anesthetics. This study was conducted to determine whether the effect-site concentration (Ce) of propofol for loss of consciousness (LOC) differs in patients undergoing preoperative chemotherapy. Methods: A total of 60 patients scheduled for surgery for colorectal cancer under general anesthesia were included in this study. Patients who had received chemotherapy comprised the experimental (C) group, and those without a previous history of chemotherapy comprised the control (N) group....

Delphi consensus on the American Society of Anesthesiologists’ physical status classification in an Asian tertiary women’s hospital
Tarig Osman, Eileen Lew, Ban L. Sng, Rajive Dabas, Konstadina Griva, et al.
Korean J Anesthesiol. 2022;75(2):168-177.

Background: The American Society of Anesthesiologists (ASA) score is generated based on patients’ clinical status. Accurate ASA classification is essential for the communication of perioperative risks and resource planning. Literature suggests that ASA classification can be automated for consistency and time-efficiency. To develop a rule-based algorithm for automated ASA classification, this study seeks to establish consensus in ASA classification for clinical conditions encountered at a tertiary women’s hospital. Methods: Thirty-seven anesthesia providers rated their agreement on a 4-point Likert scale to ASA scores assigned to items via the Delphi technique. After...

Subanesthetic intravenous ketamine vs. caudal bupivacaine for postoperative analgesia in children undergoing infra-umbilical surgeries: a non-inferiority randomized, single-blind controlled trial
Alok Kumar Sahoo, Satyajeet Misra, Bikram Kishore Behera, Anand Srinivasan, Sritam Swarup Jena, et al.
Korean J Anesthesiol. 2022;75(2):178-184.

Background: Subanesthetic intravenous (IV) ketamine acts as an analgesic and has opioid-sparing effects, particularly for acute postoperative pain; however, its effectiveness in children is understudied. The primary aim of this study was to evaluate the non-inferiority of subanesthetic IV ketamine vs. caudal bupivacaine for postoperative analgesia in children undergoing infraumbilical surgery. Methods: Children aged < 6 years were enrolled in this single-blind study and randomized to receive either subanesthetic IV ketamine (0.3 mg/kg) or caudal 0.125% bupivacaine (1 ml/kg) along with general anesthesia. Postoperative pain was assessed using...
