Mechanisms and implications in gene polymorphism mediated diverse reponses to sedatives, analgesics and muscle relaxants

Yan Sun, Hongyu Zhu, Elham Esmaeili, Xue Tang, Zhilin Wu

Korean J Anesthesiol. 2023;76(2):89-98.

Responses to sedatives, analgesics and muscle relaxants vary among patients under general anesthesia, which could be ascribed to the disparities of clinical characteristics and genetic factors of individuals. Accumulating researches have indicated that gene polymorphisms of the receptors, transporters and metabolizing enzymes associated with anesthetics play a considerable role in their efficacy. However, a systematically summarized study on the mechanisms of gene polymorphisms on pharmacodynamics and pharmacokinetics of anesthetics is still lacking. In this paper, the recent researches on pharmacogenomics of sedatives, analgesics and muscle relaxants are comprehensively reviewed, and the contributions and mechanisms of polymorphisms to the differences of individual efficacy of these drugs are discussed, so as to...

Retrospective analysis of the incidence and predictors of postoperative nausea and vomiting after orthopedic surgery under spinal anesthesia

Jae-Woo Ju, Jina Kwon, Seokha Yoo, Ho-Jin Lee

Korean J Anesthesiol. 2023;76(2):99-106.

Background: Postoperative nausea and vomiting (PONV) commonly occurs after spinal anesthesia; however, its incidence rate and predictors have been scarcely studied. Therefore, we aimed to investigate its incidence rate and potential predictors. Methods: The electronic medical records of 6,610 consecutive patients undergoing orthopedic surgery under spinal anesthesia were reviewed between January 2016 and December 2020. The primary outcome was PONV incidence within 24 h after spinal anesthesia. Along with its incidence rate, we investigated its predictors using multivariable logistic regression analysis. Results: Among the 5,691 patients included in the analysis, 1,298 (22.8%)...

Impact of transient decrease in mixed venous oxygen saturation on prognosis in off-pump coronary artery bypass surgery: a retrospective cohort study

Kyuho Lee, Kwang-Sub Kim, Jong-Kwang Park, Jun Hyug Choi, Young-Lan Kwak, et al.

Korean J Anesthesiol. 2023;76(2):107-115.

Background: The prognostic consequences of transient hemodynamic deterioration due to cardiac displacement, which is most severe during left circumflex artery (LCX) grafting in off-pump coronary artery bypass surgery (OPCAB) are unknown. This study aimed to investigate the association between mixed venous oxygen saturation (SvO2) < 60% during LCX grafting and the occurrence of composite of morbidity endpoints. Methods: Data of patients who underwent elective OPCAB between January 2010 and December 2019 were reviewed. Logistic regression analysis was performed to detect risk factors for the composite of morbidity endpoints, defined as 30-day...

Assessment of the changes in cardiac sympathetic nervous activity using the pupil size changes measured in seated patients whose stellate ganglion is blocked by interscalene brachial plexus block

Eugene Kim, Jung A Lim, Chang Hyuk Choi, So Young Lee, Seongmi Kwak, et al.

Korean J Anesthesiol. 2023;76(2):116-127.

Background: As a side effect of interscalene brachial plexus block (ISBPB), stellate ganglion block (SGB) causes reductions in pupil size (Horner’s syndrome) and cardiac sympathetic nervous activity (CSNA). Reduced CSNA is associated with hemodynamic instability when patients are seated. Therefore, instantaneous measurements of CSNA are important in seated patients presenting with Horner’s syndrome. However, there are no effective tools to measure real-time CSNA intraoperatively. To evaluate the usefulness of pupillometry in measuring CSNA, we investigated the relationship between pupil size and CSNA. Methods: Forty-two patients undergoing right arthroscopic shoulder surgery under...

Ultrasound assessment of residual gastric volume in older adults undergoing staged-bilateral total knee arthroplasty after consuming carbohydrate-containing fluids: a prospective observational study

Hyun-Jung Shin, Heeyeon Kim, Sung-Hee Han, Sang-Hwan Do, Hyo-Seok Na

Korean J Anesthesiol. 2023;76(2):128-134.

Background: We compared preoperative residual gastric volume (GV) between the first and second stages of total knee arthroplasty (TKA) in older adults after drinking carbohydrate-containing fluid 2 h prior to surgery. Methods: In this study, 36 patients, aged > 65 years, scheduled for staged bilateral TKA with one-week interval, were enrolled. The patients consumed 400 ml of carbohydrate-containing fluid 2 h prior to surgery. Before the induction of spinal anesthesia, the gastric antral cross-sectional area was measured at the first and second TKA using ultrasound, and the residual GV was calculated....

Application of competency-based education in the Korean anesthesiology residency program and survey analysis

Kyung Woo Kim, Won Joo Choe, Jun Hyun Kim

Korean J Anesthesiol. 2023;76(2):135-142.

Background: Although competency-based education (CBE) is becoming a popular form of medical education, it has not been used to train residents. Recently, the Korean Society of Anesthesiologists completed a pilot implementation and evaluation of a CBE program.This study aims to outline the experience. Methods: The chief training faculty from each hospital took a one-hour online course about CBE. Emails on the seven core competencies and their evaluation were sent ahead of a pilot core competency evaluation (CCE) to residents and faculty. The pilot CCE took place in late 2021, followed by a survey. Results: A total of 68 out of 84 hospitals participated in the pilot CCE. The survey response rate was...

Comparison of postoperative nausea and vomiting between remimazolam and propofol: a propensity score-matched, retrospective, observational, single-center cohort study

Yuji Suzuki, Shingo Kawashima, Hiroshi Makino, Matsuyuki Doi, Yoshiki Nakajima

Korean J Anesthesiol. 2023;76(2):143-151.

Background: Remimazolam is a novel ultrashort-acting benzodiazepine that has recently become available for general anesthesia. However, the incidence of postoperative nausea and vomiting (PONV) associated with remimazolam remains unknown. In this propensity score-matched, retrospective, observational study, we compared the rates of PONV between remimazolam and propofol. Methods: In this retrospective observational study, propensity score-matching was performed to minimize selection bias. Patients who received total intravenous anesthesia with remimazolam or propofol at the Hamamatsu University Hospital between August 2020 and July 2021 were enrolled in the study. Data on patient demographics, anesthetic...

Evaluation of the effects of bupivacaine combined with sugammadex on the duration of the nociceptive blockade in sciatic nerve blocks: a controlled, double-blind animal study

Omer Tasargol, Isfendiyar Darbaz, Osman Ergene, Feride Zabitler, Aziz Deniz, et al.

Korean J Anesthesiol. 2023;76(2):152-159.

Background: Animal and other experimental studies have demonstrated increased block time and quality when α- and β-cyclodextrin drugs are combined with local anesthetics. However, to our knowledge, no study has utilized γ-cyclodextrins in such a combination. In the present study, we used an animal model to evaluate the effects of different doses of the combined administration of γ-cyclodextrin (sugammadex) and bupivacaine on the duration of sciatic nerve blocks in rats. Methods: Sciatic nerve blocks were performed with a 0.20 ml mixture in all groups. For the non-experimental groups, this mixture...
