RESUMO
BACKGROUND: Although the usefulness of pulmonary function tests has been established for lung resection and coronary artery bypass surgeries, the association between preoperative pulmonary function test and postoperative respiratory complications in nonpulmonary and noncardiac surgery is inconclusive. The purpose of this study was to determine the association between preoperative forced expiratory volume in one second (FEV1) on pulmonary function test and the development of postoperative respiratory failure and/or death in patients undergoing major nonpulmonary and noncardiac surgery. METHODS: Adult patients aged ≥ 18 years and who underwent nonpulmonary and noncardiac surgery with expected moderate to high risk of perioperative complications from June 2012 to March 2019 were included. The primary exposure was preoperative FEV1 measured by pulmonary function test within six months before surgery. The primary outcome was respiratory failure (i.e., invasive positive pressure ventilation for at least 24 h after surgery or reintubation) and/or death within 30 days after surgery. A logistic regression model was used to adjust for the respiratory failure risk index, which is a scoring system that predicts the probability of postoperative respiratory failure based on patient and surgical factors, and to examine the association between preoperative FEV1 and the development of postoperative respiratory failure and/or death. RESULTS: Respiratory failure and/or death occurred within 30 days after surgery in 52 (0.9%) of 5562 participants. The incidence of respiratory failure and/or death in patients with FEV1 ≥ 80%, 70%- < 80%, 60%- < 70%, and < 60% was 0.9%, 0.6%, 1.7%, and 1.2%, respectively. Multivariable logistic regression analysis showed no significant association between preoperative FEV1 and postoperative respiratory failure and/or death (adjusted odds ratio per 10% decrease in FEV1: 1.01, 95% confidence interval: 0.88-1.17, P = 0.838). Addition of FEV1 information to the respiratory failure risk index did not improve the prediction of respiratory failure and/or death [area under the receiver operating characteristics curve: 0.78 (95% confidence interval: 0.72-0.84) and 0.78 (95% confidence interval: 0.72-0.84), respectively; P = 0.84]. CONCLUSION: We found no association between preoperative FEV1 and postoperative respiratory failure and/or death in patients undergoing major nonpulmonary and noncardiac surgery.
RESUMO
Introduction Fan therapy has gained attention as a non-pharmacological treatment for alleviating dyspnea in patients receiving palliative care and in those with chronic progressive diseases. However, the effectiveness of fan therapy for dyspnea in critically ill patients in intensive care units (ICUs) remains unclear. This study aimed to investigate the efficacy and safety of fan therapy for lung transplant patients in the ICU. Methods Fan therapy was performed on lung transplant recipients (age >18 years) who experienced dyspnea during their ICU stay. A tabletop portable fan was used to blow air on the patient's face for five minutes providing fan therapy. The intensity of dyspnea before and after the fan therapy was determined, and a statistical analysis was conducted using a paired t-test to evaluate the changes. Results Between May 2023 and February 2024, 16 patients who were admitted to the ICU following lung transplantation were screened, and eight patients received fan therapy. Fan therapy was performed at a median of postoperative day 12. Seven patients (87.5%) received mechanical ventilation via tracheostomy. The mean (±standard deviation) numerical rating scale (NRS) for dyspnea before and after fan therapy was 5.6±2.3 and 4.4±1.5, respectively (p = 0.08). The mean (±standard deviation) respiratory distress observation scale (RDOS) before and after fan therapy was 4.8 ± 2.0 and 3.8 ± 1.7, respectively (p = 0.03). No serious adverse events were observed, and no significant alterations were observed in the respiratory rate, oxygen saturation levels, pulse rate, or blood pressure. Conclusion The findings suggest that fan therapy can be safely used to relieve dyspnea in lung transplant recipients during their ICU stay. Further evaluations in larger trials are required to confirm the results of this study.
RESUMO
BACKGROUND: Acute pulmonary embolism (PE) is a life-threatening in-hospital complication. Recently, several studies have reported the clinical characteristics of PE among Japanese patients using the diagnostic procedure combination (DPC)/per diem payment system database. However, the validity of PE identification algorithms for Japanese administrative data is not yet clear. The purpose of this study was to evaluate the validity of using DPC data to identify acute PE inpatients. METHODS: The reference standard was symptomatic/asymptomatic PE patients included in the COntemporary ManageMent AND outcomes in patients with Venous ThromboEmbolism (COMMAND VTE) registry, which is a cohort study of acute symptomatic venous thromboembolism (VTE) patients in Japan. The validation cohort included all patients discharged from the six hospitals included in both the registry and DPC database. The identification algorithms comprised diagnosis, anticoagulation therapy, thrombolysis therapy, and inferior vena cava filter placement. Each algorithm's sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were estimated. RESULTS: A total of 43.4% of the validation cohort was female, with a mean age of 67.3 years. The diagnosis-based algorithm showed a sensitivity of 90.2% (222/246; 95% confidence interval [CI], 85.8-93.6%), a specificity of 99.8% (228,485/229,027; 95% CI, 99.7-99.8%), a PPV of 29.1% (222/764; 95% CI, 25.9-32.4%) and an NPV of 99.9% (228,485/229,509; 95% CI, 99.9-99.9%) for identifying symptomatic/asymptomatic PE. Additionally, 94.6% (159/168; 95% CI, 90.1-97.5%) of symptomatic PE patients were identified using the diagnosis-based algorithm. CONCLUSION: The diagnosis-based algorithm may be a relatively sensitive method for identifying acute PE inpatients in the Japanese DPC database.

STUDY OBJECTIVE: Intraoperative sedation plays an important role in the management of regional anesthesia. Few studies have investigated the association of sedation during spinal anesthesia with postoperative mortality in older patients as a primary outcome. This study aimed to test the hypothesis that sedation during spinal anesthesia increases postoperative mortality in older patients undergoing hip fracture surgery. DESIGN: Retrospective, cohort study. SETTING: Acute and subacute care hospitals in Japan. PATIENTS: Patients aged 65 years and older who received hip fracture surgery under spinal anesthesia between April 2014 and May 2022. EXPOSURE: Sedation during spinal anesthesia. MEASUREMENTS: Postoperative in-hospital all-cause mortality within 30 days. MAIN RESULTS: In total, 25,554 eligible patients were identified. Propensity score matching created 4735 pairs, and baseline patient characteristics were acceptably balanced between the sedation and non-sedation groups. There was no significant difference in 30-day postoperative mortality between the two groups (hazard ratio [95% CIs]: 0.92 [0.59-1.44]). CONCLUSIONS: There was no association between sedation during hip fracture surgery in older patients under spinal anesthesia and postoperative mortality. However, these results are limited to our population, and further prospective studies are needed to determine the safety of sedation.

PURPOSE: Various basic and clinical studies have investigated the association between the types of anesthetic agents and prognosis. However, the results have varied among studies and remain controversial. In the present study, we aimed to investigate whether the risk of all-cause mortality differs between inhaled or intravenous anesthetics in patients with gastric cancer undergoing gastrectomy. METHODS: Using a Japanese nationwide insurance claims database, we analyzed patients who underwent gastrectomy under general anesthesia for gastric cancer between January 2005 and September 2019. Postoperative outcomes were compared between two groups: those who received inhaled anesthetics (Sevoflurane, Isoflurane, or Desflurane) and those who received intravenous anesthetics (propofol), using a multivariable Cox proportional hazards model. The primary outcome was overall survival. RESULTS: Among 2671 eligible patients, 2105 were in the inhaled anesthetic group, and 566 were in the intravenous anesthetic group. The median (interquartile range) age was 58 (51-63) years, and 1979 (74.1%) were men. The median follow-up period was 795 days. We identified 56 (2.7%) and 16 (2.8%) deaths during the follow-up period in the inhaled and intravenous anesthetic use groups, respectively. There was no difference in postoperative overall survival between the two groups (hazard ratio, 0.97; 95% confidence interval, 0.56-1.70; P = 0.93). CONCLUSIONS: We found no significant difference in the postoperative risks of overall survival between inhaled and intravenous anesthesia in patients with gastric cancer undergoing gastrectomy.

BACKGROUND: The effectiveness and safety of edoxaban for venous thromboembolism (VTE) in unselected real-world patients have not been fully evaluated. METHODSâANDâRESULTS: In the Japanese nationwide administrative database, we identified 6,262 VTE patients in whom edoxaban was initiated; these patients were divided into 3 groups based on their index doses: 15 mg/day (n=235), 30 mg/day (n=4,532), and 60 mg/day (n=1,495). We evaluated patient characteristics, recurrent VTEs, and a composite endpoint of intracranial hemorrhage (ICH) and gastrointestinal (GI) bleeding. Patient characteristics among the 15-, 30-, and 60-mg edoxaban groups varied widely regarding several aspects, including age (mean 81.0, 76.2, and 65.0 years, respectively) and body weight (mean 49.5, 51.8, and 70.3 kg, respectively). At 180 days, the cumulative incidence of recurrent VTEs in the 15-, 30-, and 60-mg edoxaban groups was 4.4%, 2.6%, and 1.8%, respectively, whereas that of ICH or GI bleeding was 7.3%, 5.4%, and 3.3%, respectively. Subgroup analyses showed that the cumulative incidence of ICH or GI bleeding in patients in the 15-mg edoxaban group was 3.6% for patients aged ≥80 years, 8.4% for those with a body weight <60 kg, and 31.3% for those with renal dysfunction. CONCLUSIONS: Only a minority of patients with VTEs received a super low dose (15 mg) of edoxaban, and these patients may be at higher risk of bleeding as well as VTE recurrence.

BACKGROUND: Data on the effects of intraoperative end-tidal carbon dioxide (EtCO2) levels on postoperative organ dysfunction are limited. Thus, this study was designed to investigate the relationship between the intraoperative EtCO2 level and postoperative organ dysfunction in patients who underwent major abdominal surgery under general anesthesia. METHODS: We conducted a cohort study involving patients who underwent major abdominal surgery under general anesthesia at Kyoto University Hospital. We classified those with a mean EtCO2 of less than 35 mmHg as low EtCO2. The time effect was determined as the minutes when the EtCO2 value was below 35 mmHg, whereas the cumulative effect was evaluated by measuring the area below the 35-mmHg threshold. The outcome was postoperative organ dysfunction, defined as a composite of at least one organ dysfunction among acute renal injury, circulatory dysfunction, respiratory dysfunction, coagulation dysfunction, and liver dysfunction within 7 days after surgery. RESULTS: Of the 4,171 patients, 1,195 (28%) had low EtCO2, and 1,428 (34%) had postoperative organ dysfunction. An association was found between low EtCO2 and increased postoperative organ dysfunction (adjusted risk ratio, 1.11; 95% confidence interval [CI], 1.03-1.20; p = 0.006). Additionally, long-term exposure to EtCO2 values of less than 35 mmHg (≥224 min) was associated with postoperative organ dysfunction (adjusted risk ratio, 1.18; 95% CI, 1.06-1.32; p = 0.003) and low EtCO2 severity (area under the threshold) (adjusted risk ratio, 1.13; 95% CI, 1.02-1.26; p = 0.018). CONCLUSIONS: Intraoperative low EtCO2 of below 35 mmHg was associated with increased postoperative organ dysfunction.

BACKGROUND: Peripheral intravenous cannulation is one of the most fundamental and common procedures in medicine. Securing a peripheral line is occasionally difficult with the landmark method. Ultrasound guidance has become a standard procedure for central venous cannulation, but its efficacy in achieving peripheral venous cannulation is unclear. OBJECTIVES: To evaluate the effectiveness and safety of ultrasound guidance compared to the landmark method for peripheral intravenous cannulation in adults. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search date was 29 November 2021. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-RCTs (RCTs in which participants are systematically allocated based on data such as date of birth or recruitment) comparing the effects of ultrasound guidance to the landmark method for peripheral intravenous cannulation in adults. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes were first-pass success of cannulation, overall success of cannulation, and pain. Our secondary outcomes were procedure time for first-pass cannulation, procedure time for overall cannulation, number of attempts, patient satisfaction, and overall complications. We used GRADE to assess the certainty of the evidence. Placing a peripheral intravenous line in individuals can be classed as 'difficult', 'moderate', or 'easy'. We use the terms 'difficult participants', 'moderate/moderately difficult participants' and 'easy participants' as shorthand to characterise the difficulty level in placing a peripheral line using the landmark method. We used the original studies' definitions of difficulty levels of peripheral intravenous cannulation with the landmark method. We analysed the results in these subgroups: 'difficult participants', 'moderate participants', and 'easy participants'. We did this because we expected the effect of ultrasound-guided peripheral venous cannulation to be largest in participants classed as 'difficult' and smaller in participants classed as 'moderate' and 'easy'. MAIN RESULTS: We included 14 RCTs and two quasi-RCTs involving 2267 participants undergoing peripheral intravenous cannulation. Participants were classed as 'difficult' in 12 studies (880 participants), 'moderate' in one study (401 participants), and 'easy' in one study (596 participants). Two studies (390 participants) did not restrict by landmark method difficulty level. The overall risk of bias assessments ranged from low to high. We judged studies to be at high risk of bias mainly because of concerns about blinding for subjective outcomes. In difficult participants, ultrasound guidance increased the first-pass success of cannulation (risk ratio (RR) 1.50, 95% confidence interval (95% CI) 1.15 to 1.95; 10 studies, 815 participants; low-certainty evidence), and the overall success of cannulation (RR 1.40, 95% CI 1.10 to 1.77; 10 studies, 670 participants; very low-certainty evidence). There was no clear difference in pain (mean difference (MD) -0.20, 95% CI -1.13 to 0.72; 4 studies, 323 participants; very low-certainty evidence; numerical rating scale (NRS) 0 to 10 where 10 is maximum pain). Ultrasound guidance increased the procedure time for first-pass cannulation (MD 119.9 seconds, 95% CI 88.6 to 151.1; 2 studies, 219 participants; low-certainty evidence), and patient satisfaction (standardised mean difference (SMD) 0.49, 95% CI 0.07 to 0.92; 5 studies, 333 participants; very low-certainty evidence; NRS 0 to 10 where 10 is maximum satisfaction). Ultrasound guidance decreased the number of cannulation attempts (MD -0.33, 95% CI -0.64 to -0.02; 9 studies, 568 participants; very low-certainty evidence). Ultrasound guidance showed no clear difference in the procedure time for overall cannulation (MD -24.9 seconds, 95% CI -323.1 to 273.3; 8 studies, 413 participants; very low-certainty evidence) and overall complications (RR 0.64, 95% CI 0.37 to 1.10; 5 studies, 431 participants; low-certainty evidence). In moderate participants, ultrasound guidance increased the first-pass success of cannulation (RR 1.14, 95% CI 1.02 to 1.27; 1 study, 401 participants; moderate-certainty evidence). No studies assessed the overall success of cannulation. There was no clear difference in pain (MD 0.10, 95% CI -0.47 to 0.67; 1 study, 401 participants; low-certainty evidence; NRS 0 to 10 where 10 is maximum pain). Ultrasound guidance increased the procedure time for first-pass cannulation (MD 95.2 seconds, 95% CI 72.8 to 117.6; 1 study, 401 participants; high-certainty evidence). Ultrasound guidance showed no clear difference in overall complications (RR 0.83, 95% CI 0.38 to 1.82; 1 study, 401 participants; moderate-certainty evidence). No studies assessed the procedure time for overall cannulation, number of cannulation attempts, or patient satisfaction. In easy participants, ultrasound guidance decreased the first-pass success of cannulation (RR 0.89, 95% CI 0.85 to 0.94; 1 study, 596 participants; high-certainty evidence). No studies assessed the overall success of cannulation. Ultrasound guidance increased pain (MD 0.60, 95% CI 0.17 to 1.03; 1 study, 596 participants; moderate-certainty evidence; NRS 0 to 10 where 10 is maximum pain). Ultrasound guidance increased the procedure time for first-pass cannulation (MD 94.8 seconds, 95% CI 81.2 to 108.5; 1 study, 596 participants; high-certainty evidence). Ultrasound guidance showed no clear difference in overall complications (RR 2.48, 95% CI 0.90 to 6.87; 1 study, 596 participants; moderate-certainty evidence). No studies assessed the procedure time for overall cannulation, number of cannulation attempts, or patient satisfaction. AUTHORS' CONCLUSIONS: There is very low- and low-certainty evidence that, compared to the landmark method, ultrasound guidance may benefit difficult participants for increased first-pass and overall success of cannulation, with no difference detected in pain. There is moderate- and low-certainty evidence that, compared to the landmark method, ultrasound guidance may benefit moderately difficult participants due to a small increased first-pass success of cannulation with no difference detected in pain. There is moderate- and high-certainty evidence that, compared to the landmark method, ultrasound guidance does not benefit easy participants: ultrasound guidance decreased the first-pass success of cannulation with no difference detected in overall success of cannulation and increased pain.

BACKGROUND: Hemodynamic stabilization is a core component in the resuscitation of septic shock. However, the optimal target blood pressure remains debatable. Previous randomized controlled trials suggested that uniformly adopting a target mean arterial pressure (MAP) higher than 65 mmHg for all adult septic shock patients would not be beneficial; however, it has also been proposed that higher target MAP may be beneficial for elderly patients, especially those with arteriosclerosis. METHODS: A multicenter, pragmatic single-blind randomized controlled trial will be conducted to compare target MAP of 80-85 mmHg (high-target) and 65-70 mmHg (control) in the resuscitation of septic shock patients admitted to 28 hospitals in Japan. Patients with septic shock aged ≥65 years are randomly assigned to the high-target or control groups. The target MAP shall be maintained for 72 h after randomization or until vasopressors are no longer needed to improve patients' condition. To minimize the adverse effects related to catecholamines, if norepinephrine dose of ≥ 0.1 µg/kg/min is needed to maintain the target MAP, vasopressin will be initiated. Other therapeutic approaches, including fluid administration, hydrocortisone use, and antibiotic choice, will be determined by the physician in charge based on the latest clinical guidelines. The primary outcome is all-cause mortality at 90 days after randomization. DISCUSSION: The result of this trial will provide great insight on the resuscitation strategy for septic shock in the era of global aged society. Also, it will provide the better understanding on the importance of individualized treatment strategy in hemodynamic management in critically ill patients.

BACKGROUND: Dyspnea is an important problem that might affect the clinical course after lung transplantation; however, the prevalence, risk factors, and relevant outcomes of dyspnea in the intensive care unit (ICU) after lung transplantation remain unknown. METHODS: This retrospective, observational study enrolled consecutive patients aged ≥ 20 years who were admitted to the ICU after lung transplantation between January 2010 and December 2020. The main outcome measure was provider-documented dyspnea identified based on a comprehensive retrospective chart review to extract dyspnea episodes (e.g., documented words related to "dyspnea," "shortness of breath," or "breathlessness"). RESULTS: This study included 184 lung transplant recipients, including 115 bilateral (63%) and 69 single (37%) lung transplants. Fifty-four transplants were from living donors (29%), and 130 were from deceased donors (71%). Dyspnea was documented in 116 patients (63%). Multivariate analysis identified bilateral lung transplantation (odds ratio = 5.127; 95% confidence interval, 2.020-13.014; P < .001) as a risk factor for dyspnea. In addition, postoperative anxiety (odds ratio = 18.605; 95% confidence interval, 7.748-44.674; P < .001) was independently associated with dyspnea. Patients with documented dyspnea showed delayed rehabilitation (P < .001) and weaning from mechanical ventilation (P < .001) and a longer ICU stay (P < .001). CONCLUSION: This study demonstrated that the prevalence of dyspnea in the ICU after lung transplantation was frequent and identified bilateral lung transplantation as a risk factor. Dyspnea caused a delay in rehabilitation and weaning from mechanical ventilation. Extensive evaluation and care for dyspnea and anxiety may enhance patient recovery.

BACKGROUND: Jacobsen syndrome is a rare genetic disorder with multiple congenital anomalies and platelet abnormalities caused by chromosome 11 deletion. CASE PRESENTATION: A 7-month-old boy with thrombocytopenia underwent ventricular septal defect closure. At the beginning of surgery, the platelet count was 168 × 103/µL, and heparinized kaolin with heparinase reaction time (HKH-R), which represents clot formation time, was prolonged at 30.4 min. Platelet transfusion was continued, and at the end of surgery, the platelet count and HKH-R values improved to 215 × 103/µL and 15 min, respectively. CONCLUSIONS: As anesthetic management of patients with abnormal platelet function, the viscoelasticity test might be useful in evaluating hemostatic capacity.
RESUMO
In liver transplantation for end-stage liver failure, monitoring of continuous cardiac output (CCO) is used for circulatory management due to hemodynamic instability. CCO is often measured using the minimally invasive FloTrac/Vigileo system (FVS-CCO), instead of a highly invasive pulmonary artery catheter (PAC-CCO). The FVS has improved accuracy due to an updated cardiac output algorithm, but the effect of this change on the accuracy of FVS-CCO in liver transplantation is unclear. In this study, we assessed agreement between fourth-generation FVS-CCO and PAC-CCO in 20 patients aged ≥ 20 years who underwent scheduled or emergency liver transplantation at Kyoto University Hospital from September 2019 to June 2021. Consent was obtained before surgery and data were recorded throughout the surgical period. Pearson correlation coefficient (r), Bland-Altman and 4-quadrant plot analyses were performed on the extracted data. A total of 1517 PAC-CCO vs. FVS-CCO data pairs were obtained. The mean PAC-CCO was 8.73 L/min and the mean systemic vascular resistance was 617.5 dyne·s·cm-5, r was 0.48, bias was 1.62 L/min, the 95% limits of agreement were - 3.04 to 6.27, and the percentage error was 54.36%. These results show that agreement and trending between fourth-generation FVS-CCO and PAC-CCO are low in adult liver transplant recipients.

BACKGROUND: Septic shock is a common and life-threatening condition that requires intensive care. Intensive care units (ICUs) in Japan are classified into ICUs and high-dependency care units (HDUs), depending on presence of full-time certified intensivists and the number of assigned nurses. Compared with other developed countries, there are fewer intensive care beds and certified intensivists in Japan; therefore, non-intensivists often treat patients with septic shock in HDUs. It is unknown where we should treat patients with septic shock because no studies have compared the clinical outcomes between ICU and HDU treatment. This study aimed to elucidate which units should admit patients with septic shock by comparing mortality data and resource use between ICU and HDU admissions. METHODS: In this retrospective cohort study, we used a nationwide Japanese administrative database to identify adult patients with septic shock who were admitted to ICUs or HDUs between January 2010 and February 2021. The patients were divided into two groups, based on admittance to ICU or HDU on the day of hospitalization. The primary outcome was 30-day all-cause mortality adjusted for covariates using Cox regression analyses; the secondary outcomes were the length of ICU or HDU stay and length of hospital stay. RESULTS: Of the 10,818 eligible hospitalizations for septic shock, 6584 were in the ICU group, and 4234 were in the HDU group. Cox regression analyses revealed that patients admitted to the ICUs had lower 30-day mortality (adjusted hazard ratio: 0.89; 95% confidence interval: 0.83-0.96; P = 0.005). Linear regression analyses showed no significant difference in hospital length of stay or ICU or HDU length of stay. CONCLUSIONS: An association was observed between ICU admission and lower 30-day mortality in patients with septic shock. These findings could provide essential insights for building a more appropriate treatment system.
RESUMO
BACKGROUND: Apart from saving the lives of coronavirus disease (COVID-19) patients on mechanical ventilation (MV), recovery from the sequelae of prolonged MV (PMV) is an emerging issue.c METHODS: We conducted a retrospective study among consecutive adult COVID-19 patients admitted to an intensive care unit (ICU) in Kobe, Japan, between March 3, 2020, and January 31, 2021, and received invasive MV. Clinical outcomes included in-hospital mortality and recovery from COVID-19 in survivors regarding organ dysfunction, respiratory symptoms, and functional status at discharge. We compared survivors' outcomes with MV durations of >14 days and ≤14 days. RESULTS: We included 85 patients with a median age of 69 years (interquartile range, 64-75 years); 76 (89%) patients had at least 1 comorbidity, 72 (85%) were non-frail, and 79 (93%) were functionally independent before COVID-19 infection. Eighteen patients (21%) died during hospitalization. At discharge, 59/67 survivors (88%) no longer required respiratory support, 50 (75%) complained of dyspnea, and 40 (60%) were functionally independent. Of the survivors, 23 patients receiving MV for >14 days had a worse recovery from COVID-19 at discharge compared with those on MV for ≤14 days, as observed using the Barthel index (median: 35 [5-65] vs. 100 [85-100]), ICU mobility scale (8 [5-9] vs. 10 [10-10]), and functional oral intake scale (3 [1-7] vs. 7 [7-7]) (P < 0.0001). CONCLUSION: Although four-fifths of the patients survived and >50% of survivors demonstrated clinically important recovery in organ function and functional status during hospitalization, PMV was related to poor recovery from COVID-19 at discharge.

Background: This study examined the relationship between the use of fentanyl-based intravenous patient-controlled analgesia (ivPCA) and the incidence of a clinically significant event (CSE), while considering both the analgesic effects and side effects in laparoscopic gynecological surgery. Methods: This study included 816 patients undergoing laparoscopic gynecological surgery under general anesthesia at Kyoto University Hospital between 2012 and 2018. The primary exposure was the use of fentanyl-based ivPCA. We defined an outcome measureCSEthat integrates severe wound pain and vomiting assumed to negatively affect patient recovery. We performed multivariable logistic regression analysis to assess the independent relationship between ivPCA use and CSE. Results: Multivariable logistic regression analysis revealed that fentanyl-based ivPCA was independently associated with increased CSE (adjusted odds ratio (95% confidence interval): 1.80 (1.24−2.61), p = 0.002). Use of ivPCA was associated with a reduced incidence of postoperative severe wound pain (adjusted odds ratio (95% confidence interval): 0.50 (0.27−0.90), p = 0.022), but was also associated with an increased incidence of vomiting (adjusted odds ratio (95% confidence interval): 2.65 (1.79−3.92), p < 0.001). Conclusion: The use of fentanyl-based ivPCA in laparoscopic gynecological surgery is associated with increased CSE.
RESUMO
Gynecologic laparoscopic surgery has a high incidence of postoperative nausea and vomiting (PONV). Studies suggest that low intraoperative end-tidal carbon dioxide (EtCO2) is associated with an increased incidence of PONV, but the results have not been consistent among studies. This study investigated the association between intraoperative EtCO2 and PONV in patients undergoing gynecologic laparoscopic surgeries under general anesthesia. This retrospective cohort study involved patients who underwent gynecologic laparoscopic surgeries under general anesthesia at Kyoto University Hospital. We defined low EtCO2 as a mean EtCO2 of < 35 mmHg. Multivariable modified Poisson regression analysis examined the association between low EtCO2 and PONV during postoperative two days and the postoperative length of hospital stay (PLOS). Of the 739 patients, 120 (16%) had low EtCO2, and 430 (58%) developed PONV during postoperative two days. There was no substantial association between low EtCO2 and increased incidence of PONV (adjusted risk ratio: 0.96; 95% confidence interval [CI] 0.80-1.14; p = 0.658). Furthermore, there was no substantial association between low EtCO2 and prolonged PLOS (adjusted difference in PLOS: 0.13; 95% CI - 1.00 to 1.28; p = 0.816). Intraoperative low EtCO2, specifically a mean intraoperative EtCO2 below 35 mmHg, was not substantially associated with either increased incidence of PONV or prolonged PLOS.

OBJECTIVES: The purpose of this study was to evaluate the incidence, clinical characteristics and prognosis of postoperative symptomatic venous thromboembolism (VTE) in Japan. DESIGN: Retrospective observational study. Two data sets, Contemporary ManageMent AND outcomes in patients with Venous ThromboEmbolism (COMMAND VTE) Registry and Japanese Society of Anesthesiologists (JSA) annual report, were used for current analyses. SETTING: Eighteen of 29 centres participated in the COMMAND VTE Registry. PARTICIPANTS: Acute symptomatic patients with VTE who had undergone surgery 2 months prior to the diagnosis at 18 centres from January 2010 to December 2013 were identified in the COMMAND VTE Registry. From each centre's JSA annual report, the overall population that had received anaesthetic management during this period was retrieved. INTERVENTIONS: None. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the incidences and clinical characteristics of postoperative symptomatic VTE. The secondary outcomes were recurrent VTE, major bleeding and all-cause death. RESULTS: We identified 137 patients with postoperative symptomatic VTE, including 57 patients with pulmonary embolism. The incidences of postoperative symptomatic VTE and pulmonary embolism were 0.067% and 0.028%, respectively, based on data from 2 03 943 patients who underwent surgery, managed by anaesthesiologists, during the study period. The incidences of postoperative symptomatic VTE varied widely, depending on surgical and anaesthetic characteristics. Postoperative symptomatic VTE occurred at a median of 8 days after surgery, with 58 patients (42%) diagnosed within 7 days. The cumulative incidence, 30 days after VTE, of recurrent VTE, major bleeding, and all-cause death was 3.0%, 5.2%, and 3.7%, respectively. CONCLUSION: This study, combining the large real-world VTE and anaesthesiology databases in Japan revealed the incidence, clinical features and prognosis of postoperative symptomatic VTE, providing useful insights for all healthcare providers involved in various surgeries. TRIAL REGISTRATION: Not applicable.

BACKGROUND: Worldwide, pediatric sedation for magnetic resonance imaging is a standard practice; however, there are few studies on its trends and patterns. AIMS: This study aimed to investigate the trends and patterns of pediatric sedation for magnetic resonance imaging in Japan and determine the incidence of and risk factors for adverse events/interventions. METHODS: This longitudinal descriptive study assessed children (age < 15 years) who underwent sedation for magnetic resonance imaging between April 2012 and December 2019 in Japan using a nationwide claims database. We assessed the patients' demographic characteristics, time trends in sedatives, sedative patterns by age, and adverse events/interventions within two post-sedation days. Further, we used multivariable logistic regression models to explore factors related to the incidence of adverse events/interventions. RESULTS: We identified 29 187 cases (median age, 2.0 years; 55.2% males). The most common sedative was triclofos sodium (n = 18 812, 51.7%). There was an increasing trend in barbiturate use (17.0% [2012] to 25.0% [2019]) and decreasing trends in the use of triclofos sodium (56.4% [2012] to 47.7% [2019]) and chloral hydrate (15.6% [2012] to 10.8% [2019]). We identified 534 adverse events/interventions in 460 cases (1.5%). Multivariable logistic regression analyses revealed that the incidence of adverse events/interventions mainly increased with the number of sedatives (≥3; adjusted odds ratio, 5.10; 95% confidence interval, 3.67-7.10) and unscheduled setting (adjusted odds ratio, 6.28; 95% confidence interval, 4.85-8.61); further, it decreased with high hospital procedure volume (adjusted odds ratio, 0.62; 95% confidence interval, 0.49-0.78). CONCLUSIONS: Based on a Japanese real-world setting, there is an increasing trend in barbiturate use and decreasing trends in the use of triclofos sodium and chloral hydrate in pediatric sedation for magnetic resonance imaging. Low hospital procedure volumes were associated with an increased risk of adverse events/interventions.

Background: Using neuromuscular blocking drugs (NMBDs) for patients with myasthaenia gravis remains a challenge in perioperative management. Sugammadex has enabled the safe use of NMBDs. We investigated whether the adverse outcomes, and the treatment used for myasthaenic crises and tracheotomy, are affected by NMBD use in patients with myasthaenia gravis under general anaesthesia. Methods: Patients with myasthaenia gravis who underwent general anaesthesia were retrieved from the Diagnostic Procedure Combination/Per-Diem Payment systems in Japan between 1 January 2010 and 30 November 2020. This database did not contain information on the severity of myasthaenia gravis (Osserman classification). Patients who received rocuronium and sugammadex were compared with those who did not receive NMBDs after propensity-score matching. We excluded patients who underwent emergency or cardiac surgery or tracheal intubation before anaesthesia. The primary outcome was receipt of postoperative treatment used for myasthaenic crises. Results: Among 2304 surgical patients with comorbid myasthaenia gravis, propensity-score matching identified 788 patients administered rocuronium and sugammadex and 449 not administered NMBDs. On comparing the treatment used for myasthaenic crises, we found no significant difference between the two groups (6.2% vs 5.3%; hazard ratio, 1.14; 95% confidence interval, 0.70-1.85). Conclusions: Use of rocuronium and sugammadex in patients with myasthaenia gravis did not significantly affect the receipt of postoperative treatment used for myasthaenic crises compared with no use of NMBDs. As well as the severity of myasthaenia gravis was not fully adjusted, it is unclear whether intraoperative administration of rocuronium with the use of sugammadex postoperatively is acceptable and further investigations are needed.
