RESUMEN

Aims: To assess whether mechanical circulatory support (MCS), including intra-aortic balloon pump (IABP) or veno-arterial extracorporeal membrane oxygenation (ECMO), can help improve neurological outcomes in patients with out-of-hospital cardiac arrest (OHCA). Methods: This is a retrospective observational cohort study performed in China Medical University Hospital, Taichung, Taiwan. Adult patients with OHCA admitted between January 2015 and June 2023. Quantitative score of vasoactive-inotropic agents and qualitative interventions of MCS, including IABP and ECMO after OHCA. Multivariate regression evaluated the efficacy of each MCS approach in patients stratified by the vasoactive-inotropic score (VIS). Results: A total of 334 patients were included and analyzed, 122 (36.5%) had favorable neurological outcomes and 215 (64.4%) survived ≥90 days. These patients were stratified by VIS: 0-25, 26-100, 101-250, and >250. In patients with a VIS > 100, ECMO with or without IABP ensured favorable neurological outcomes and survival after OHCA compared to non-MCS interventions (p < 0.001). For patients with a VIS ≤ 100, IABP alone was beneficial, with no significant outcome difference from non-MCS interventions (p > 0.05). Conclusions: ECMO with or without IABP therapy may improve post-OHCA neurological outcomes and survival in patients with an expected VIS-24 h > 100 (e.g., epinephrine dose reaches 3 mg during CPR).

RESUMEN

OBJECTIVES: To determine the predictive role of combined assessment of vasoactive-inotropic score and lactate for the prognosis of patients with postcardiotomy cardiogenic shock requiring venoarterial extracorporeal membrane oxygenation. METHODS: The data of adult patients with postcardiotomy cardiogenic shock requiring venoarterial extracorporeal membrane oxygenation between January 2015 and December 2018 at a tertiary hospital was retrospectively analyzed. The incidence of in-hospital mortality and other clinical outcomes were analyzed. The associations of vasoactive-inotropic score and lactate and in-hospital mortality were assessed using logistic regression analysis. RESULTS: 222 patients were included and divided into four groups according to the cut-off points of vasoactive-inotropic score (24.3) and lactate level (6.85 mmol/L). The in-hospital mortality rates were 37.7%, 50.7%, 54.8% and 76.5% for the four groups (P < 0.001), while the rates of successful weaning off extracorporeal membrane oxygenation were 73.9%, 69%, 61.3% and 39.2% respectively (P = 0.001). The group 1 and group 2 exhibited significant differences compared to group 4 in both in-hospital mortality and weaning rates (P < 0.05). There was a statistically significant difference in the incidence of multiple organ dysfunction between group 1 and group 4 (P < 0.05). Groups 1, 2 and 3 demonstrated significantly improved cumulative 30-day survival compared with group 4 (log-rank test, P < 0.05). Logistic regression analysis revealed that age, vasoactive-inotropic score > 24.3 and lactate > 6.85 mmol/L were independently predictive of in-hospital mortality. CONCLUSIONS: Among patients with postcardiotomy cardiogenic shock requiring venoarterial extracorporeal membrane oxygenation, the initiation before reaching vasoactive-inotropic score > 24.3 and lactate > 6.85 mmol/L was associated with improved in-hospital outcomes, suggesting that combined assessment of VIS and lactate may be instructive for determining the initiation of venoarterial extracorporeal membrane oxygenation.

RESUMEN

Background: This study investigated the association between vasoactive medication exposure and mortality risk in patients with sepsis using the norepinephrine equivalent (NEE) score and vasoactive-inotropic score (VIS). Methods: This retrospective cohort study included adult patients with sepsis requiring vasoactive agents. The data were extracted from the Medical Information Mart for Intensive Care IV database. The primary outcome was 28-day mortality. Multivariate Cox regression was used to elucidate the relationship between vasoactive medication exposure and 28-day mortality, as quantified by the VIS and NEE score. Hazard ratios with 95% confidence intervals (CI) for 28-day mortality were generated, and forest plots were constructed to present the results of univariate and multivariate analyses. The Kaplan-Meier method was used to analyze the cumulative incidence of 28-day mortality. A nomogram was constructed to predict the prognosis of patients with sepsis. Results: The present study encompassed 9,032 patients diagnosed with sepsis who received vasoactive therapy, of which 4,229 patients were further analyzed at the second hour after the onset of sepsis. Distinct variations in demographic data were observed between survivors (n = 3,265, 77.21%) and non-survivors (n = 964, 22.79%). Multivariate analysis indicated that several factors, including VIS >15.04 (p = 0.001), NEE >0.10 (p < 0.001), heart rate (p = 0.045), mean arterial pressure (p = 0.009), respiratory rate (p < 0.001), oxygen saturation (p < 0.001), blood urea nitrogen (BUN) (p = 0.001), and the Acute Physiology and Chronic Health Evaluation II (p < 0.001), were significantly associated with 28-day mortality in the patients with sepsis. The NEE score, respiratory rate, oxygen saturation, and BUN were incorporated into the nomogram model with a concordance index of 0.779 and an area under the curve of 0.802 (95% CI 0.787-0.818). Conclusion: We found that the VIS and NEE score had favorable values for predicting mortality risk in patients with sepsis in the intensive care units. The VIS and NEE score in the second hour after sepsis onset were independently associated with 28-day mortality in patients with sepsis.

RESUMEN

Background: In the early postoperative stage after heart transplantation, there is a lack of predictive tools to guide postoperative management. Whether the vasoactive-inotropic score (VIS) can aid this prediction is not well illustrated. Methods: In total, 325 adult patients who underwent heart transplantation at our center between January 2015 and December 2018 were included. The maximum VIS (VISmax) within 24 h postoperatively was calculated. The Kaplan-Meier method was used for survival analysis. A logistic regression model was established to determine independent risk factors and to develop a nomogram for a composite severe adverse outcome combining early mortality and morbidity. Results: VISmax was significantly associated with extensive early outcomes such as early death, renal injury, cardiac reoperation and mechanical circulatory support in a grade-dependent manner, and also predicted 90-day and 1-year survival (p < 0.05). A VIS-based nomogram for the severe adverse outcome was developed that included VISmax, preoperative advanced heart failure treatment, hemoglobin and serum creatinine. The nomogram was well calibrated (Hosmer-Lemeshow p = 0.424) with moderate to strong discrimination (C-index = 0.745) and good clinical utility. Conclusion: VISmax is a valuable prognostic index in heart transplantation. In the early post-transplant stage, this VIS-based nomogram can easily aid intensive care clinicians in inferring recipient status and guiding postoperative management.

RESUMEN

Background: Postarrest acute kidney injury (AKI) is a major health burden because it is associated with prolonged hospitalization, increased dialysis requirement, high mortality, and unfavorable neurological outcomes. Managing hemodynamic instability during the early postarrest period is critical; however, the role of quantified vasopressor dependence in AKI development in relation to illness severity remains unclear. Methods: A retrospective, observational cohort study that enrolled 411 non-traumatic adult cardiac arrest survivors without pre-arrest end-stage kidney disease between January 2017 and December 2019, grouped according to their baseline kidney function. The criteria for kidney injury were based on the Kidney Disease: Improving Global Outcomes definition and AKI staging system. The degree of vasopressor dependence within the first 24 h following return of spontaneous circulation (ROSC) was presented using the maximum vasoactive-inotropic score ( VIS max ). Results: Of the 411 patients, 181 (44%) had early AKI after ROSC. Patients with AKI showed an increased risk of in-hospital mortality (adjusted OR [aOR] 5.40, 95% CI 3.36-8.69, p < 0.001) and unfavorable neurological outcome (aOR 5.70, 95% CI 3.45-9.43, p < 0.001) compared to patients without AKI. The risk of adverse outcomes increased with illness severity. Patients with vasopressor support had an increased risk of early AKI. A low VIS max was associated with AKI stage 1-2 (aOR 2.51, 95% CI 1.20-5.24), whereas a high VIS max was associated with an increased risk for AKI stage 3 (aOR 2.46, 95% CI 1.28-4.75). Conclusions: Early AKI is associated with an increased risk of in-hospital mortality and unfavorable neurologic recovery in cardiac arrest survivors. Postarrest VIS max is an independent predictor of the development and severity of AKI following ROSC, regardless of baseline kidney function.

RESUMEN

The relationship between VISmax and mortality in patients undergoing major abdominal surgery remains unclear. This study aims to evaluate the association between VISmax and both short-term and long-term all-cause mortality in patients undergoing major abdominal surgery, VISmax was calculated (VISmax = dopamine dose [µg/kg/min] + dobutamine dose [µg/kg/min] + 100 × epinephrine dose [µg/kg/min] + 10 × milrinone dose [µg/kg/min] + 10,000 × vasopressin dose [units/kg/min] + 100 × norepinephrine dose [µg/kg/min]) using the maximum dosing rates of vasoactives and inotropics within the first 24 h postoperative ICU admission. The study included 512 patients first admitted to the intensive care unit (ICU) who were administered vasoactive drugs after major abdominal surgery. The data was extracted from the medical information mart in intensive care-IV database. VISmax was stratified into five categories: 0-5, > 5-15, > 15-30, > 30-45, and > 45. Compared to patients with the lowest VISmax (≤ 5), those with the high VISmax (> 45) had an increased risk of 30-day mortality (hazard ratio [HR] 3.73, 95% CI 1.16-12.02; P = 0.03) and 1-year mortality (HR 2.76, 95% CI 1.09-6.95; P = 0.03) in fully adjusted Cox models. The ROC analysis for VISmax predicting 30-day and 1-year mortality yielded AUC values of 0.69 (95% CI 0.64-0.75) and 0.67 (95% CI 0.62-0.72), respectively. In conclusion, elevated VISmax within the first postoperative 24 h after ICU admission was associated with increased risks of both short-term and long-term mortality in patients undergoing major abdominal surgery.

RESUMEN

AIMS: This study evaluated how well serial pulse pressure (PP) and PP adjusted by the vasoactive inotropic score (VIS) predicted venoarterial extracorporeal membrane oxygenation (VA-ECMO) weaning success and clinical outcomes in acute myocardial infarction complicated by cardiogenic shock (AMI-CS) patients. METHODS AND RESULTS: A total of 213 patients with AMI-CS who received VA-ECMO between January 2010 and August 2021 were enrolled in the institutional ECMO registry. Serial PP and VIS were measured immediately, 12, 24, and 48 h after VA-ECMO insertion. PP adjusted by VIS was defined as PP/√VIS. The primary outcome was successful VA-ECMO weaning. Successful weaning from VA-ECMO was observed in 151 patients (70.9%). Immediately after VA-ECMO insertion, PP [successful vs. failed weaning, 26.0 (15.5-46.0) vs. 21.0 (12.5-33.0), P = 0.386] and PP/√VIS [11.1 (5.1-25.0) vs. 6.0 (3.1-14.2), P = 0.118] did not differ between the successful and failed weaning groups. Serial PP and PP adjusted by VIS at 12, 24, and 48 h after VA-ECMO insertion were significantly higher in patients with successful weaning than those with failed weaning [successful vs. failed weaning, 24.0 (4.0-38.0) vs. 12.5 (6.0-25.5), P = 0.007 for 12 h PP, and 10.1 (5.7-22.0) vs. 2.9 (1.7-5.9), P < 0.001 for 12 h PP/√VIS]. The 12 h PP/√VIS showed better discriminative function for successful weaning than 12 h PP alone [area under the curve (AUC) 0.80, 95% confidence interval (CI) 0.72-0.88, P < 0.001 vs. AUC 0.67, 95% CI 0.57-0.77, P = 0.002]. Patients with a low 12 h PP/√VIS (≤7) had higher rates of in-hospital mortality (44.4% vs. 19.8%, P < 0.001) and 6 month follow-up mortality (hazard ratio 2.41, 95% CI 1.49-3.90, P < 0.001) than those with a high 12 h PP/√VIS (>7). CONCLUSIONS: PP adjusted by VIS taken 12 h following VA-ECMO initiation can predict weaning from VA-ECMO more successfully than PP alone, and its low value was associated with a higher risk of mortality in AMI-CS patients.

RESUMEN

INTRODUCTION: This study aimed to investigate the predictive value of the vasoactive-inotropic score (VIS) at different time points for postoperative prolonged mechanical ventilation (PMV) in adult congenital heart disease patients undergoing surgical treatment combined with coronary artery bypass grafting. METHODS: Patients were divided into two groups that developed PMV or not. The propensity score matching method was applied to reduce the effects of confounding factors between the two groups. VIS at different time points (VIS at the end of surgery, VIS6h, VIS12h, and VIS12h max) after surgery were recorded and calculated. The value of VIS in predicting PMV was analyzed by the receiver operating characteristic (ROC) curve, and multivariate logistic regression was used to analyze independent risk factors. RESULTS: Among 250 patients, 52 were in the PMV group, and 198 were in the non-PMV group. PMV rate was 20.8%. After propensity score matching, 94 patients were matched in pairs. At each time point, the area under the ROC curve predicted by VIS for PMV was > 0.500, among which VIS at the end of surgery was the largest (0.805). The optimal cutoff point for VIS of 6.5 could predict PMV with 78.7% sensitivity and 72.3% specificity. VIS at the end of surgery was an independent risk factor for PMV (odds ratio=1.301, 95% confidence interval 1.091~1.551, P<0.01). CONCLUSION: VIS at the end of surgery is an independent predictor for PMV in patients with adult congenital heart disease surgical treatment combined with coronary artery bypass grafting.

RESUMEN

BACKGROUND: Early extubation (EEx) is defined as the removal of the endotracheal tube within 8 h postoperatively. The present study involved determining the availability and threshold of the vasoactive-inotropic score (VIS) for predicting EEx in adults after elective rheumatic heart valve surgery. METHODS: The present study was designed as a single-center retrospective cohort study which was conducted with adults who underwent elective rheumatic heart valve surgery with CPB. The highest VIS in the immediate postoperative period was used in the present study. The primary outcome, the availability of VIS for EEx prediction and the optimal threshold value were determined using ROC curve analysis. The gray zone analysis of the VIS was performed by setting the false negative or positive rate R = 0.05, and the perioperative risk factors for prolonged EEx were identified by multivariate logistic analysis. The postoperative complications and outcomes were compared between different VIS groups. RESULTS: Among the 409 patients initially screened, 379 patients were ultimately included in the study. The incidence of EEx was determined to be 112/379 (29.6%). The VIS had a good predictive value for EEx (AUC = 0.864, 95% CI: [0.828, 0.900], P < 0.001). The optimal VIS threshold for EEx prediction was 16.5, with a sensitivity of 71.54% (65.85-76.61%) and a specificity of 88.39% (81.15-93.09%). The upper and lower limits of the gray zone for the VIS were determined as (12, 17.2). The multivariate logistic analysis identified age (OR, 1.060; 95% CI: 1.017-1.106; P = 0.006), EF% (OR, 0.798; 95% CI: 0.742-0.859; P < 0.001), GFR (OR, 0.933; 95% CI: 0.906-0.961; P < 0.001), multiple valves surgery (OR, 4.587; 95% CI: 1.398-15.056; P = 0.012), and VIS > 16.5 (OR, 12.331; 95% CI: 5.015-30.318; P < 0.001) as the independent risk factors for the prolongation of EEx. The VIS ≤ 16.5 group presented a greater success rate for EEx, a shorter invasive ventilation support duration, and a lower incidence of complications than did the VIS > 16.5 group, while the incidence of reintubation was similar between the two groups. CONCLUSION: In adults, after elective rheumatic heart valve surgery, the highest VIS in the immediate postoperative period was a good predictive value for EEx, with a threshold of 16.5.

RESUMEN

Background: Vasopressors and inotropes are crucial in managing cardiogenic shock (CS) as they enhance microcirculation in patients. Numerous studies have demonstrated the adverse outcomes associated with excessive use of vasoactive drugs and the vasoactive drug scoring system has emerged as a valuable prognostic tool, particularly in pediatric patients. This study aimed to examine the prognostic significance of the Vasoactive Inotropic Score (VIS) in adult patients with CS receiving veno-arterial extracorporeal membrane oxygenation (VA-ECMO) treatment. Methods: This retrospective multi-center study involved 2,453 adult patients who underwent VA-ECMO in China between 2015 and 2021. Among them, 1,742 adult patients with CS following VA-ECMO were finally included. The maximum VIS (VISmax) was determined by considering the highest doses of vasoactive and inotropic drugs administered within the first 6 hours before ECMO initiation. Based on the VISmax, patients were classified into two groups: 0-20 and >20. The primary outcome of this study was in-hospital mortality. Results: A total of 1,146 patients were included in the high VISmax group, while 596 patients were assigned to the low VISmax group. Overall, 882 (50.6%) patients experienced in-hospital mortality, with significantly higher rates observed among those with higher VISmax scores (41.4% for VIS ≤20 versus 68.3% for VIS >20; P<0.001). Similar trends were observed for 30-day mortality (40.7% for VIS ≤20 versus 64.9% for VIS >20; P<0.001). Multivariable regression analysis demonstrated that a VIS score exceeding 20 independently predicted in-hospital mortality [odds ratio (OR) 2.64; 95% confidence interval (CI): 2.10-3.33; P<0.001]. The receiver operating characteristic (ROC) analysis revealed that VIS had an area under the curve (AUC) of 0.65 (95% CI: 0.63-0.68; P<0.001) as a predictor of in-hospital mortality, with an optimal cutoff value of 20.1. Moreover, the VIS exhibited good predictive ability for in-hospital mortality in patients with acute myocarditis (AUC 0.70; 95% CI: 0.63-0.78; P<0.001). Conclusions: Firstly, higher maximum level of VIS within the first 6 hours before ECMO initiation independently predicted poorer clinical outcomes in patients supported with ECMO for CS. Secondly, VIS exceeding 20 was significantly associated with increased risks of in-hospital mortality and 30-day mortality. Thirdly, when categorized by the cause of CS, a high VIS exhibited good predictive ability in patients with acute myocardial infarction, heart failure, and acute myocarditis.

RESUMEN

Objective: This study evaluated the predictive value of the vasoactive-ventilation-renal (VVR) score in identifying the risk of weaning failure after cardiac surgery and developing a nomogram model to help physicians improve the success rate of weaning from mechanical ventilation in adult patients undergoing postoperative cardiac surgery. Methods: Clinical data were retrospectively collected from adult patients who underwent extracorporeal circulation cardiac surgery at the First Affiliated Hospital of Nanjing Medical University between August 2022 and April 2023 and who were subsequently transferred to the Intensive Care Unit (ICU) and treated with vasoactive drugs. Patients were divided into successful and unsuccessful weaning groups based on first-attempt weaning success. Variable selection was regularized using univariate logistic regression and Least absolute shrinkage and selection operator (LASSO) regularization. Multivariate logistic regression was performed to identify predictors and a nomogram was created to predict the risk of weaning failure. Results: A total of 519 patients were included in the study. After selecting multiple stepwise variables, the VVR score before weaning, the modified Sequential Organ Failure Assessment (mSOFA) score on weaning day, and mechanical ventilation duration before weaning were determined as predictive indicators of weaning failure in adult patients after cardiac surgery. The optimal cut-off values for these indicators were 18.46 points, 4.33 points, and 20.50 h, respectively. The predictive model constructed using these three factors demonstrated good predictive performance. Conclusions: The VVR score before weaning accurately predicts the probability of weaning failure in adult patients after cardiac surgery. The weaning risk-predictive nomogram model, established based on the VVR score, mSOFA score, and mechanical ventilation duration before weaning, demonstrated robust predictive ability.

RESUMEN

BACKGROUND: The objective of this study is to conduct a systematic review and meta-analysis examining the relationship between the vasoactive-inotropic score (VIS) and patient outcomes in surgical settings. METHODS: Two independent reviewers searched PubMed, Web of Science, EMBASE, Scopus, Cochrane Library, Google Scholar, and CNKI databases from November 2010, when the VIS was first published, to December 2022. Additional studies were identified through hand-searching the reference lists of included studies. Eligible studies were those published in English that evaluated the association between the VIS and short- or long-term patient outcomes in both pediatric and adult surgical patients. Meta-analysis was performed using RevMan Manager version 5.3, and quality assessment followed the Joanna Briggs Institute (JBI) Critical Appraisal Checklists. RESULTS: A total of 58 studies comprising 29,920 patients were included in the systematic review, 34 of which were eligible for meta-analysis. Early postoperative VIS was found to be associated with prolonged mechanical ventilation (OR 5.20, 95% CI 3.78-7.16), mortality (OR 1.08, 95% CI 1.05-1.12), acute kidney injury (AKI) (OR 1.26, 95% CI 1.13-1.41), poor outcomes (OR 1.02, 95% CI 1.01-1.04), and length of stay (LOS) in the ICU (OR 3.50, 95% CI 2.25-5.44). The optimal cutoff value for the VIS as an outcome predictor varied between studies, ranging from 10 to 30. CONCLUSION: Elevated early postoperative VIS is associated with various adverse outcomes, including acute kidney injury (AKI), mechanical ventilation duration, mortality, poor outcomes, and length of stay (LOS) in the ICU. Monitoring the VIS upon return to the Intensive Care Unit (ICU) could assist medical teams in risk stratification, targeted interventions, and parent counseling.

RESUMEN

OBJECTIVE: To assess the effect of cardiovascular medications on the neurodevelopment of preterm infants, as measured by calculated cumulative time of vasoactive-inotropic score (VISct). METHODS: A retrospective study was conducted on preterm infants who developed significant hypotension defined as a mean BP more than 2SDs below the mean for GA and received treatment with duration > 6 hours for each hypotensive episode, we calculated the vasoactive inotropic score (VIS) and cumulative exposure to cardiovascular medications over time (VISct). The composite Bayley III was reported from the high-risk follow-up clinic for the surviving infants between 18 to 21 months corrected age. RESULTS: VISct was significantly higher in infants with abnormal neurodevelopment. Cognitive Bayley was the most affected component with median (IQR) VISct 882.5(249,2047) versus 309(143,471) (p-value 0.012), followed by language function with VISct 786(261,1563.5), versus 343(106.75,473.75) (p-value 0.016) when those with Bayley III <85 were compared with those with normal Bayley IIIs. CONCLUSION: High VISct scores may have negative effect on cognitive and language neurodevelopmental outcomes.

RESUMEN

AIMS: The aim of this trial was to compare the clinical effects of intraoperative haemoadsorption versus standard care in patients undergoing orthotopic heart transplantation (OHT). METHODS AND RESULTS: In a randomized, controlled trial, OHT recipients were randomized to receive intraoperative haemoadsorption or standard care. Outcomes were vasoactive-inotropic score (VIS), frequency of vasoplegic syndrome (VS) in the first 24 h; post-operative change in procalcitonin (PCT) and C-reactive protein (CRP) levels; intraoperative change in mycophenolic acid (MPA) concentration; frequency of post-operative organ dysfunction, major complications, adverse immunological events and length of in-hospital stay and 1-year survival. Sixty patients were randomized (haemoadsorption group N = 30, control group N = 25 plus 5 exclusions). Patients in the haemoadsorption group had a lower median VIS and rate of VS (VIS: 27.2 [14.6-47.7] vs. 41.9 [22.4-63.2], P = 0.046, and VS: 20.0% vs. 48.0%, P = 0.028, respectively), a 6.4-fold decrease in the odds of early VS (OR: 0.156, CI: 0.029-0.830, P = 0.029), lower PCT levels, shorter median mechanical ventilation (MV: 25 [19-68.8] hours vs. 65 [23-287] hours, P = 0.025, respectively) and intensive care unit stay (ICU stay: 8.5 [8.0-10.3] days vs. 12 [8.5-18.0] days, P = 0.022, respectively) than patients in the control group. Patients in the haemoadsorption versus control group experienced lower rates of acute kidney injury (AKI: 36.7% vs. 76.0%, P = 0.004, respectively), renal replacement therapy (RRT: 0% vs. 16.0%, P = 0.037, respectively) and lower median per cent change in bilirubin level (PCB: 2.5 [-24.6 to 71.1] % vs. 72.1 [11.2-191.4] %, P = 0.009, respectively) during the post-operative period. MPA concentrations measured at pre-defined time points were comparable in the haemoadsorption compared to control groups (MPA pre-cardiopulmonary bypass: 2.4 [1.15-3.60] µg/mL vs. 1.6 [1.20-3.20] µg/mL, P = 0.780, and MPA 120 min after cardiopulmonary bypass start: 1.1 [0.58-2.32] µg/mL vs. 0.9 [0.45-2.10] µg/mL, P = 0.786). The rates of cardiac allograft rejection, 30-day mortality and 1-year survival were similar between the groups. CONCLUSIONS: Intraoperative haemoadsorption was associated with better haemodynamic stability, mitigated PCT response, lower rates of post-operative AKI and RRT, more stable hepatic bilirubin excretion, and shorter durations of MV and ICU stay. Intraoperative haemoadsorption did not show any relevant adsorption effect on MPA. There was no increase in the frequency of early cardiac allograft rejection related to intraoperative haemoadsorption use.

RESUMEN

INTRODUCTION: The use of Del Nido Cardioplegia (DNC) has been extended in the latest years from pediatrics to adult cardiac surgery with encouraging results. We sought to investigate clinical and biochemical outcomes in adult patients who underwent cardiac surgery with different degrees of complexity who received DNC for myocardial protection. METHODS: Data on one-thousand patients were retrospectively collected from 2020 to 2022. The only exclusion criteria was off-pump adult cardiac surgery. Surgical procedures weight was categorized according EuroSCORE II in six groups: Single-CABG(G1), isolated non-CABG(mitral) (G2), isolated non-CABG(aortic) (G3), isolated non-CABG(any) (G4), 2-procedures(G5), 3/more-procedures(G6). Primary endpoint was to identify a binomial correlation between hs-TnT/CK-MB and the cross-clamp time (X-Clamp). A secondary endpoint was the comparison between the treatment groups of the vasoactive-inotropic score (VIS) and the need of mechanical circulatory support (MCS). RESULTS: A linear correlation was identified between hs-TnT and X-clamp in the overall population (rho:0.447, p< .001) and in the treatment groups (G1:rho=0.357, p< .001/G2:rho=0.455, p< .001/G3:rho=0.307, p= .001/G4:rho=0.165, p= .257/G5:rho=0.157, p= .031/G6:rho=0.226, p= .015). Similarly, a linear correlation between CK-MB and X-clamp in the overall population (rho=0.457, p< .001) and treatment group (G1:rho=0.282, p< .001/G2:rho=0.287, p= .025/G3:rho=0.211, p= .009/G4:rho=0.0878, p= .548/G5:rho=0.309, p< .001/G6: rho=0.212, p= .024) was identified. As regard for the secondary endpoint, no differences were reported between the treatment groups in terms of VIS and MCS (VIS G1:7; G2:4; G3:7; G4:7, G5:5.5, G6:6, p-value= .691) (MCS G1: 4.5%; G2:4.8%; G3:3.3%; G4:3.1%; G5:1.4%; G6:5.3%; p-value= .372). CONCLUSIONS: Del Nido Cardioplegia is a safe and useful tool in adult cardiac surgery allowing operators to achieve a stable and durable cardioplegic arrest. Despite accounting with different types of surgery, the six subgroups of our study population showed similar perioperative results.

RESUMEN

After the initiation of veno-arterial extracorporeal membrane oxygenation (V-A ECMO) for hemodynamic support, patients often require vasopressor and inotropic medications to support their blood pressure and cardiac contractility. The vasoactive-inotropic score (VIS) is a standardized calculation of vasopressor and inotrope equivalence, which uses coefficients for each medication to calculate a total value. This study evaluated the association between the 30-day survival of patients receiving V-A ECMO support and the VIS calculated 24 h after ECMO cannulation (VIS24). This was a single-center, retrospective, observational cohort study. The median VIS24 of the entire cohort was 6.0, and was determined as a cutoff for comparison. Patients with a VIS24 < 6.0 were assigned to a group, and those with a VIS24 ≥ 6.0 were assigned to a second group. Patients with a VIS24 < 6.0 had higher 30-day survival than those with a VIS24 ≥ 6.0 (54.5% vs 41.4%; p = 0.03). The group with a VIS24 < 6.0 also had significantly improved survival to decannulation of ECMO support; however, there was no difference in the survival to hospital discharge. We conducted a secondary analysis of quartiles and determined that individuals with a VIS24 > 11.4 had the lowest survival in the cohort. This finding may help identify patients with the lowest probability of 30-day survival in those receiving V-A ECMO for hemodynamic support.
