Revolutionizing trauma care: advancing coagulation management and damage control anesthesia

Despite advances in emergency transfer systems and trauma medicine, the incidence of preventable deaths due to massive hemorrhage remains high. Recent immunological research has elucidated key mechanisms underlying trauma-induced coagulopathy in the early stages of trauma, including sympathoadrenal stimulation, shedding of the glycocalyx, and endotheliopathy. Consequently, the condition progresses to fibrinogen depletion, hyperfibrinolysis, and platelet dysfunction. Coexisting factors such as uncorrected acidosis, hypothermia, excessive crystalloid administration, and a history of anticoagulant use exacerbate coagulopathy. This study introduces damage-control anesthetic management based on recent insights into damage-control resuscitation, emphasizing the importance of rapid transport, timely bleeding control, early administration of antifibrinolytics and fibrinogen concentrates, and maintenance of calcium levels and body temperature. Additionally, this study discusses brain-protective strategies for trauma patients with brain injuries and the utilization of cartridge-based viscoelastic assays for goal-directed coagulation management in trauma settings. This comprehensive approach may provide potential insights for anesthetic management in the fast-paced field of trauma medicine.

Prevalence and natural course of incidental gastric subepithelial tumors

Background/Aims@#Gastric subepithelial tumors (SETs) are often encountered during the upper gastrointestinal endoscopic screening. We assessed the prevalence of gastric SETs and the risk factors for their progression. @*Methods@#We reviewed the electronic medical records of 30,754 patients who underwent upper gastrointestinal endoscopic screening at our medical center between January 2013 and December 2016. @*Results@#Among the 30,754 patients examined, 599 (1.94%) had gastric SETs. The prevalence increased with age and was 9.56% in patients aged ≥70 years. In total, 262 patients underwent serial endoscopy for more than 6 months. The median age was 68 years (interquartile range [IQR], 61–74), and the number of females was 167 (63.7%). During a median follow-up of 58 months (IQR, 38–75), 22 patients (8.4%) showed significant changes in tumor size. An irregular border (odds ratio, 4.623; 95% confidence interval, 1.093–19.558; p=0.037) was a significant risk factor for progression. Seven patients underwent surgical or endoscopic resections. The pathologies of gastric SETs included leiomyomas (n=3), gastrointestinal stromal tumors (n=2), and lipomas (n=2). @*Conclusions@#The prevalence of gastric SETs increases with age. Most gastric SETs do not progress during long-term endoscopic examinations, and the risk of an increase in size is low in asymptomatic small SETs without irregular borders.

Analytic Hierarchy Process approach to estimate weights of menu management in the school foodservice / 한국영양학회지

Purpose@#This study used the Analytic Hierarchy Process to evaluate the relative importance of the factors that school nutrition teachers and dietitians consider during menu planning for school foodservices across various educational levels. @*Methods@#An online survey was conducted from December 2023 to January 2024. The hierarchical structure for school foodservice menu management was developed through content analysis, consisting of five high-level categories and 3–4 low-level factors.Questionnaires were distributed to 395 nutrition teachers and dietitians from kindergarten, elementary, middle, and high schools nationwide. One hundred and sixty-six responses were received, resulting in a 42.0% return rate. These responses were analyzed using Microsoft Excel and SPSS Statistics. @*Results@#The most commonly referenced sources for school foodservice menu planning were ‘menus obtained from websites’ (19.4%). The most significant challenge encountered was ‘incorporating students’ preferences’ (18.6%). In the hierarchy of categories considered for school foodservice menu management, ‘employees and facilities’ ranked highest (0.2347), followed by ‘preference’ (0.2312), ‘nutrition balance’ (0.2027), ‘cooking process’ (0.1726), and ‘food materials’ (0.1588). Within each category, the top-ranked factors were ‘employees’ cooking skills’ (0.3759), ‘students’ preferences’ (0.4310), ‘dietary reference intakes’ (0.4968), ‘foodservice hygiene’ (0.4374), and ‘food costs’ (0.4213). The study also compared the relative importance of factors according to the educational levels, and the top-ranked factors were the same across all educational levels. In particular, ‘students’ preferences’, ‘dietary reference intake’, and ‘food costs’ aligned with the top three challenges in school foodservice menu planning. @*Conclusion@#Enhancing working conditions for school foodservice employees and developing menu planning methods that accommodate students’ preferences are necessary. These findings will provide foundational data for future school foodservice menu management strategies.

Korean clinical practice guidelines for diagnostic and procedural sedation / 대한마취과학회지

Safe and effective sedation depends on various factors, such as the choice of sedatives, sedation techniques used, experience of the sedation provider, degree of sedation-related education and training, equipment and healthcare worker availability, the patient’s underlying diseases, and the procedure being performed. The purpose of these evidence-based multidisciplinary clinical practice guidelines is to ensure the safety and efficacy of sedation, thereby contributing to patient safety and ultimately improving public health. These clinical practice guidelines comprise 15 key questions covering various topics related to the following: the sedation providers; medications and equipment available; appropriate patient selection; anesthesiologist referrals for high-risk patients; pre-sedation fasting; comparison of representative drugs used in adult and pediatric patients; respiratory system, cardiovascular system, and sedation depth monitoring during sedation; management of respiratory complications during pediatric sedation; and discharge criteria. The recommendations in these clinical practice guidelines were systematically developed to assist providers and patients in sedation-related decision making for diagnostic and therapeutic examinations or procedures. Depending on the characteristics of primary, secondary, and tertiary care institutions as well as the clinical needs and limitations, sedation providers at each medical institution may choose to apply the recommendations as they are, modify them appropriately, or reject them completely.

Factors influencing consumers’ continuance intention in online grocery shopping: a cross-sectional study using application behavior reasoning theory / 대한지역사회영양학회지

Objectives@#Online grocery shopping has gained traction with the digital transformation of retail. This study constructs a behavioral model combining values, attitudes, and reasons for behavior—specifically, facilitators and resistance—to provide a more novel discussion and further understand the relative influences of the various factors affecting continuance intention in online grocery shopping. @*Methods@#Data were collected through an online questionnaire from consumers who had engaged in online grocery shopping during the past month in Seoul, Korea. All collected data were analyzed using descriptive analysis, and model validation was performed using partial least squares structural equation modeling. @*Results@#Continuance intention is primarily driven by facilitative factors (compatibility, relative advantage, and ubiquity). Attitude can also positively influence continuance intention. Although resistance factors (price, tradition, and risk) do not significantly affect continuance intention, they negatively affect attitude. Values significantly influence consumers’ reasoning processes but not their attitude. @*Conclusions@#These findings explain the key influences on consumers’ online grocery shopping behavior in Seoul and provide additional discussion and literature on consumer behavior and market management. To expand the online grocery market, consumers should be made aware of the potential benefits of the online channel; the barriers they encounter should be reduced. This will help sustain online grocery shopping behavior. Furthermore, its positive impact on attitude will further strengthen consumers’ continuance intention.

Vertebral Venous Congestion That May Mimic Vertebral Metastasis on Contrast-Enhanced Chest Compu

Objective@#This study aimed to determine the prevalence of vertebral venous congestion (VVC) in patients with chemoport insertion, evaluate the imaging characteristics of nodular VVC, and identify the factors associated with VVC. @*Materials and Methods@#This retrospective single-center study was based on follow-up contrast-enhanced chest computed tomography (CT) of 1412 adult patients who underwent chemoport insertion between January 2016 and December 2016. The prevalence of venous stenosis, reflux, and VVC were evaluated. The imaging features of nodular VVC, including specific locations within the vertebral body, were analyzed. To identify the factors associated with VVC, patients with VVC were compared with a subset of patients without VVC who had been followed up for > 3 years without developing VVC after chemoport insertion.Toward this, a multivariable logistic regression analysis was performed. @*Results@#After excluding 333 patients, 1079 were analyzed (mean age ± standard deviation, 62.3 ± 11.6 years; 540 females).The prevalence of VVC was 5.8% (63/1079), with all patients (63/63) demonstrating vertebral venous reflux and 67% (42/63) with innominate vein stenosis. The median interval between chemoport insertion and VVC was 515 days (interquartile range, 204–881 days). The prevalence of nodular VVC was 1.5% (16/1079), with a mean size of 5.9 ± 3.1 mm and attenuation of 784 ± 162 HU. Nodular VVC tended to be located subcortically. Forty-four patients with VVC underwent CT examinations with contrast injections in both arms; the VVC disappeared in 70% (31/44) when the contrast was injected in the arm contralateral to the chemoport site. Bevacizumab use was independently associated with VVC (odds ratio, 3.45; P < 0.001). @*Conclusion@#The prevalence of VVC and nodular VVC was low in patients who underwent chemoport insertion. Nodular VVC was always accompanied by vertebral venous reflux and tended to be located subcortically. To avoid VVC, contrast injection in the arm contralateral to the chemoport site is preferred.

Successful Endoscopic Submucosal Dissection Using Open Peroral Endoscopic Myotomy for Duodenal Neuroendocrine Tumor / 대한소화기학회지

Duodenal neuroendocrine tumors (NETs) are subepithelial tumors that are difficult to remove endoscopically, particularly when located just beyond the pylorus. This paper reports a case of a successful endoscopic submucosal dissection (ESD) using open gastric peroral endoscopic myotomy (POEM) for a remnant duodenal NET detected after endoscopic mucosal resection (EMR). A 67-year-old male presented with a 5 mm remnant duodenal NET close to the pylorus after EMR for a duodenal polypoid lesion performed four months earlier. Duodenal ESD was performed under conscious sedation using I-type and IT II knives. The tumor adhered to the fibrotic tissue, and the submucosal cushion was insufficient. Open gastric POEM was performed concurrently during ESD, resulting in the complete resection of the NET. This case suggests that while challenging, open gastric POEM can serve as a valuable technique for endoscopic resection in cases of early gastric cancer or duodenal masses located around the pylorus.

Time to presentation and mortality outcomes among patients with diabetes and acute myocardial infarction

Background/Aims@#Due to limited real-world evidence on the association between time to presentation (T2P) and outcomes following acute myocardial infarction and diabetes (AMI-DM), we investigated the characteristics of patients with AMI-DM and their outcomes based on their T2P. @*Methods@#4,455 patients with AMI-DM from a Korean nationwide observational cohort (2011–2015) were divided into early and late presenters according to symptom-to-door time. The effects of T2P on three-year all-cause mortality were estimated using inverse probability of treatment weighting (IPTW) and survival analysis. @*Results@#The incidence of all-cause mortality was consistently higher in late presenters than in early presenters (11.4 vs. 17.2%; p < 0.001). In the IPTW-adjusted dataset, the incidence of all-cause mortality was numerically higher in late presenters than in early presenters (9.1 vs. 12.4%; p = 0.072). In the survival analysis, the cumulative incidence of all-cause mortality was significantly higher in late presenters than in early presenters before and after IPTW. In the subgroup with ST-elevation myocardial infarction, late presenters had a higher incidence of cardiac death than early presenters before (4.8 vs. 10.5%; p < 0.001) and after IPTW (4.2 vs. 9.7%; p = 0.034). In the initial glycated hemoglobin (HbA1c)-stratified analysis, these effects were attenuated in patients with HbA1c ≥ 9.0% before (adjusted hazard ratio [HR]: 1.45, 95% confidence interval [CI]: 0.80-2.64) and after IPTW (adjusted HR: 0.82, 95% CI: 0.40-1.67). @*Conclusions@#Late presentation was associated with higher mortality in patients with AMI-DM; therefore, multifaceted and systematic interventions are needed to decrease pre-hospital delays.

Removal of iatrogenic orbital foreign bodies with a 3D model

Facial foreign body (FB) is common after trauma, but iatrogenic orbital FB is a rare and unexpected complication of facial FB removal surgery. We present the case of a 43-year-old man with a glass FB in his nose. During the operation, this FB broke into two pieces, and the larger one pierced into the left orbit, close to the eyeball. A three-dimensional (3D) model was made that accurately recreated the shape and position of the FB in the orbit, according to which the FB was removed. 3D-printing technology is a great tool when dealing with complex facial FB.

Comparison of remimazolam–remifentanil and propofol–remifentanil during laparoscopic cholecystectomy

Background@#Remimazolam is a novel benzodiazepine with fast onset and short half-life. We compared the effects of remimazolam and propofol on recovery profiles for general anesthesia in patients undergoing laparoscopic cholecystectomy. @*Methods@#We randomly assigned 108 patients to either a remimazolam (n=54) or propofol (n=54) group. Remimazolam and propofol were used for induction and maintanance of anesthesia. Following anesthesia, we recorded the time until an Aldrete score of 9 was achieved as the primary surrogate marker of complete recovery. The time to reach a Modified Observer’s Assessment of Alertness/Sedation (MOAA/S) score of 2 and the time from the end of anesthesia to eye opening time, recovery time of orientation, time to spontaneous breathing, extubation time, and the time required for analgesics were measured. Heart rate, blood pressure, and bispectral index were assessed before, during, and after pneumoperitoneum. @*Results@#We included 101 patients in the analysis. In the remimazolam group, it took longer to reach an Aldrete score of 9 after the drug infusion ended (P = 0.031). There was no difference in the time to reach MOAA/S 2 between the two groups. The time to eye opening, recovery time of orientation, and time required for analgesics were longer and heart rate was higher in the remimazolam group. Neither blood pressure, nor extubation time differed between groups. @*Conclusions@#Remimazolam and propofol provided safe induction and maintenance of anesthesia in patients undergoing laparoscopic cholecystectomy. The recovery time from anesthesia was longer than that with propofol. Fewer hemodynamic changes were observed with remimazolam, but further studies are needed.

Rescue Endovascular Treatment to Prevent Neurological Deterioration in Acute Symptomatic Bilateral Vertebral Artery Occlusion / 신경중재치료의학

Bilateral vertebral artery occlusive disease has been considered as a favorable condition with good collaterals. However, the prognosis of acute ischemic stroke secondary to symptomatic bilateral vertebral artery occlusion (BVAO) and endovascular treatment (EVT) has rarely been reported. We retrospectively selected patients with acute ischemic stroke admitted for symptomatic BVAO between January 2020 and February 2023. All patients with ischemic stroke were evaluated for ischemic lesion and arterial status using brain imaging and angiography. The prognosis of acute stroke with symptomatic BVAO was compared between EVT and conventional treatment. Outcomes were evaluated using modified Rankin Scale (mRS) score at 3 months follow-up. Within the study period, 17 of 2,655 acute ischemic stroke patients were diagnosed with ischemic stroke with symptomatic BVAO. The median age of these patients was 70 (interquartile range 44–89) years, and 13 (76%) were male. Seven patients received emergent EVT with stenting and 10 patients received conventional medical treatment only. Nine of 10 patients with conventional treatment had in-hospital stroke progression and developed new ischemic lesions in the pons and midbrain. Five patients with fetal and hypoplastic posterior communicating artery presented bilateral cerebral peduncular lesions. At 3 months follow-up, 6 patients (35%) had favorable outcomes (mRS 0–2), of which 5 were treated with vertebral artery stenting and 1 received conventional treatment. Ischemic stroke in patients with acute symptomatic BVAO is uncommon. However, stroke progression is common, and the prognosis of most patients is poor. Rescue management such as EVT might be considered for symptomatic BVAO.

Endovascular Reperfusion Therapy in Minor Stroke with Neurologic Deterioration beyond 24 Hours from Onset / 신경중재치료의학

Purpose@#Patients with minor stroke (National Institutes of Health Stroke Scale score ≤5) and large vessel occlusion (LVO) often experience neurological deterioration >24 hours after onset. However, the efficacy of endovascular reperfusion therapy in these patients remains unclear. The aim of this study was to determine the efficacy and safety of reperfusion therapy in patients with minor stroke and neurological deterioration >24 hours after onset. @*Materials and Methods@#Data were retrospectively reviewed from patients between January 2019 and April 2022 who met the following criteria: (1) minor stroke and small definitive ischemic lesions at initial visit, (2) onset to neurological deterioration >24 hours, (3) cortical signs, Alberta Stroke Program Early computed tomography (CT) Score >6 points, and large artery occlusion confirmed by CT angiography at neurological deterioration. Efficacy and safety outcomes were based on final thrombolysis in cerebral infarction (TICI), incidence of symptomatic intracranial hemorrhage (ICH), and mortality. Outcomes were assessed using the modified Rankin Scale (mRS) at 3 months. Good outcome was defined as a mRS of 0, 1, or 2. @*Results@#Data from 26 patients (38.4% female, mean age 75.8 years) were analyzed; 18 (69.2%) had a good outcome. A final TICI of 2b or 3 was observed in 24 (92.3%) patients. No other adverse events, including dissection, vasospasm or distal embolization, were observed during the procedures. Hemorrhagic events occurred in 8 patients after the procedure; however, there were no symptomatic ICHs. Good prognostic factors were younger age (P=0.062) and carotid stenting (P=0.025). @*Conclusion@#Endovascular reperfusion therapy performed in selected patients with minor stroke, LVO, and neurological deterioration >24 hours after stroke onset demonstrated favorable outcomes and safety.

The Etiology of Acute Stroke with Experience of Repeated Upper Extremity Deep Vein Thrombosis

In stroke patients, upper extremity deep vein thrombosis (UEDVT) is uncommon compared with lower extremity. Unlike the blood stasis in lower extremity, UEDVT has been developed by secondary cause. We reported a case of stroke patient with repeated UEDVT, presenting superficial venous congestion, who was finally diagnosed with pulmonary adenocarcinoma. The cause of stroke was non-bacterial thromboembolism formed at the mitral valve. Our case shows that unexpected UEDVT should be closely evaluated for higher coagulable status such as a malignancy.

A Case of Schwannoma in the Interarytenoid Area Presenting as Papillomatous Mass

Schwannoma is a type of benign neurogenic tumor which may be derived from the nerve sheath. It is common in the head and neck region, but it occurs relatively rarely in the larynx. The laryngeal schwannoma can occur in the false vocal cord, aryepiglottic fold and epiglottis etc. The typical feature of it is a round submucosal well-encapsulated mass, and papillomatous appearance of its surface is extremely rare. A 76-year-old male came to our clinic with voice change and globus sense. The rigid laryngoscopy showed round papillomatous mass in the interarytenoid area. We performed laryngeal microsurgery, and he was pathologically diagnosed as schwannoma. We report an interesting and didactic case that has an atypical feature of laryngeal schwannoma with relevant literature review.

Endoscopic Ultrasonography-guided Gastrojejunostomy for Patients with Gastric Outlet Obstruction and Pyloric Metal Stent Dysfunction / 대한소화기학회지

A 52-year-old woman with a gastric outlet obstruction (GOO) caused by pyloric cancer underwent pyloric endoscopic self-expandable metal stent (SEMS) insertion. She presented with abdominal distension 40 days later. The SEMS was dysfunctional, and endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) was performed using an endoscopic nasobiliary drainage tube. A 16 mm×31 mm Niti-S ™ HOT SPAXUS™ (TaeWoong Medical, Gimpo, Korea) was inserted successfully between the stomach and the adjacent jejunum. After the procedure, the patient had a good oral intake for more than seven months. GOO is a mechanical obstructive condition caused by various benign and malignant conditions. Traditionally, surgical GJ and SEMS insertion have been used to treat GOOs. EUS-GJ is a feasible treatment option for patients with GOO and a pyloric metal stent dysfunction.

Analgesic effects of ultrasound-guided fourquadrant transversus abdominis plane in patients with cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: a prospective, randomized, controlled study

Background@#Postoperative pain occurring after cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is difficult to control because of extensive surgical injuries and long incisions. We assessed whether the addition of a four-quadrant transabdominal plane (4Q-TAP) block could help in analgesic control. @*Methods@#Seventy-two patients scheduled to undergo elective CRS with HIPEC and intravenous patient-controlled analgesia (IV PCA) were enrolled. The patients received 4Q-TAP blocks in a 10 ml mixture of 2% lidocaine and 0.75% ropivacaine per site (4Q-TAP group, n = 36) or normal saline (control group, n = 33). Oxycodone in the post-anesthesia care unit (PACU) and pethidine or tramadol in the ward were used as rescue analgesics. The primary outcome was less than 3 times of rescue analgesic administration (%) in the ward for 5 postoperative days. Secondary endpoints included oxycodone requirement in PACU, fentanyl doses of IV PCA, morphine milligram equivalent (MME) of total opioid use, hospital stay, and postoperative complications. @*Results@#During 5 postoperative days, there was no difference in pain scores and total rescue analgesic administration between two groups. However, the use of oxycodone in PACU (P = 0.011), fentanyl requirement in IV PCA (P = 0.029), and MME/kg of total opioid use (median, 2.35 vs. 3.21 mg/kg, P = 0.009) were significantly smaller in the 4Q-TAP group. Hospital stay and incidence of postoperative morbidity were similar in both groups. @*Conclusions@#The 4Q-TAP block enhanced multimodal analgesia and decreased opioid requirements in patients with CRS with HIPEC, but did not change postoperative recovery outcomes.

Effect of ulinastatin on the inflammatory response after video-assisted thoracic lobectomy in patients with lung cancer: a randomized controlled study / 中华医学杂志(英文版)

BACKGROUND@#The first-line treatment for lung cancer is surgical resection, and one-lung ventilation (OLV) is the most basic anesthetic management method in lung surgery. During OLV, inflammatory cytokines are released in response to the lung tissue damage and promote local and contralateral lung damage through the systemic circulation. We designed a randomized, prospective study to evaluate the effect of the urinary trypsin inhibitor (UTI) ulinastatin on the inflammatory response after video-assisted thoracic lobectomy in patients with lung cancer.@*METHODS@#Adult patients aged 19 to 70 years, who were scheduled for video-assisted thoracic lobectomy surgery to treat lung cancer between May 2020 and August 2020, were enrolled in this randomized, prospective study. UTI (300,000 units) mixed with 100 mL of normal saline in the ulinastatin group and 100 mL of normal saline in the control group was administered over 1 h after inducing anesthesia.@*RESULTS@#The baseline (T0) interferon-γ (IFN-γ)/interleukin-4 (IL-4) ratio was not different between the groups (6941.3 ± 2778.7 vs. 6954.3 ± 2752.4 pg/mL, respectively; P  > 0.05). The IFN-γ/IL-4 ratio was significantly higher in ulinastatin group at 30 min after entering the recovery room than control group (20,148.2 ± 5054.3 vs. 6674.0 ± 2963.6, respectively; adjusted P < 0.017).@*CONCLUSION@#Administering UTI attenuated the anti-inflammatory response, in terms of INF-γ expression and the IFN-γ/IL-4 ratio, after video-assisted thoracic surgery in lung cancer patients.@*TRIAL REGISTRATION@#Clinical Research Information Service of Korea National Institute of Health (CRIS), KCT0005533.

Perioperative Management for the Patients with Obstructive Sleep Apnea

The prevalence of obstructive sleep apnea (OSA) is on the rise worldwide due to an increase in metabolic syndrome, obesity, and aging. Patients with OSA are at higher risk of perioperative complications than those without OSA; however, OSA is often not diagnosed before surgery. For patients diagnosed with OSA or who are judged to be at risk of OSA by various screening tools, safe preparation for respiratory depression or difficult airway is critical. Exaggerated respiratory depression often occurs in response to commonly used sedatives and analgesics, and there is a high risk of hypoxic events due to difficulty in maintaining the airway. Currently, there is insufficient training of health care providers to screen and diagnose patients with OSA, and several screening tools are incomplete. In addition, the guidelines for optimal monitoring and perioperative management of patients with OSA have not yet been clearly established. In the present work, the author aims to explain the latest findings useful to sleep physicians regarding the overall management, including pre-operative evaluation and preparation, intraoperative anesthetic management, and post-operative general care and analgesic strategies, of patients at risk of OSA.

A Case of Glottic Cavernous Hemangioma Mimicking Malignancy in Elderly Patient

The etiology of laryngeal hemangioma is unclear, and it is classified into infant and adult types. The former is capillary hemangioma and relatively common, the latter is cavernous type and very rare. The adult laryngeal hemangioma mainly occurs in supraglottis and glottis. A 75-year-old man came to our clinic with a voice change that started four months ago. The laryngoscopic finding showed that the surface of oval-shaped mass is covered with turbid exudates. We performed the laryngeal microsurgery with CO2 laser. The mass was pathologically proven as cavernous hemangioma. We report a very rare and didactic case with review of relevant literature.

Analysis of Surveys to Determine the Real Prices of Ingredients used in School Foodservice / 대한지역사회영양학회지

Objectives@#The purpose was to identify the ingredients that are usually surveyed for assessing real prices and to present the demand for such surveys by nutrition teachers and dietitians for ingredients used by school foodservice. @*Methods@#A survey was conducted online from December 2019 to January 2020. The survey questionnaire was distributed to 1,158 nutrition teachers and dietitians from elementary, middle, and high schools nationwide, and 439 (37.9% return rate) of the 1,158 were collected and used for data analysis. @*Results@#The ingredients which were investigated for price realities directly by schools were industrial products in 228 schools (51.8%), fruits in 169 schools (38.4%), and specialty crops in 166 schools (37.7%). Moreover, nutrition teachers and dietitians in elementary, middle, and high schools searched in different ways for the real prices of ingredients. In elementary schools, there was a high demand for price information about grains, vegetables or root and tuber crops, special crops, fruits, eggs, fishes, and organic and locally grown ingredients by the School Foodservice Support Centers. Real price information about meats, industrial products, and pickled processed products were sought from the external specialized institutions. In addition, nutrition teachers and dietitians in middle and high schools wanted to obtain prices of all of the ingredients from the Offices of Education or the District Office of Education. @*Conclusions@#Schools want to efficiently use the time or money spent on research for the real prices of ingredients through reputable organizations or to co-work with other nutrition teachers and dietitians. The results of this study will be useful in understanding the current status of the surveys carried out to determine the real price information for ingredients used by the school foodservice.
