Need For Vasopressors Research Articles

Epidemiology of cardiogenic shock using the Shock Academic Research Consortium (SHARC) consensus definitions.

The Shock Academic Research Consortium (SHARC) recently proposed pragmatic consensus definitions to standardize classification of cardiogenic shock (CS) in registries and clinical trials. We aimed to describe contemporary CS epidemiology using the SHARC definitions in a cardiac intensive care unit (CICU) population. The Critical Care Cardiology Trials Network (CCCTN) is a multinational research network of advanced CICUs coordinated by the TIMI Study Group (Boston, MA). Cardiogenic shock was defined as a cardiac disorder resulting in SBP < 90 mmHg for ≥30 min [or the need for vasopressors, inotropes, or mechanical circulatory support (MCS) to maintain SBP ≥ 90 mmHg] with evidence of hypoperfusion. Primary aetiologic categories included acute myocardial infarction-related CS (AMI-CS), heart failure-related CS (HF-CS), and non-myocardial (secondary) CS. Post-cardiotomy CS was not included. Heart failure-related CS was further subcategorized as de novo vs. acute-on-chronic HF-CS. Patients with both cardiogenic and non-cardiogenic components of shock were classified separately as mixed CS. Of 8974 patients meeting shock criteria (2017-23), 65% had isolated CS and 17% had mixed shock. Among patients with CS (n = 5869), 27% had AMI-CS (65% STEMI), 59% HF-CS (72% acute-on-chronic, 28% de novo), and 14% secondary CS. Patients with AMI-CS and de novo HF-CS were most likely to have had concomitant cardiac arrest (P < 0.001). Patients with AMI-CS and mixed CS were most likely to present in more severe shock stages (SCAI D or E; P < 0.001). Temporary MCS use was highest in AMI-CS (59%). In-hospital mortality was highest in mixed CS (48%), followed by AMI-CS (41%), similar in de novo HF-CS (31%) and secondary CS (31%), and lowest in acute-on-chronic HF-CS (25%; P < 0.001). SHARC consensus definitions for CS classification can be pragmatically applied in contemporary registries and reveal discrete subpopulations of CS with distinct phenotypes and outcomes that may be relevant to clinical practice and future research.

The association of obesity and in-hospital outcomes among patients undergoing ablation for atrial fibrillation: a propensity-score matched analysis

Abstract Background Obesity is a strong risk factor for atrial fibrillation (AF), and it can affect the prognosis of AF. However, the impact of obesity (BMI≥30 kg/m²) on postoperative complications after AF ablation has not been extensively studied. We aimed to evaluate the association of obesity with in-hospital outcomes among patients with AF who ablation procedures. Methods The study utilized the National Inpatient Sample (NIS) database 2016-2020. Patients were divided into obese and non-obese groups and matched with propensity score matching (1:1). This matching involved adjusting for baseline variables (including age, gender, primary expected payer, race, and median household income) and comorbidities (including diabetes, hypertension, hyperlipidemia, history of coronary artery bypass grafting (CABG), chronic kidney disease, hyperthyroidism, cardiomyopathy, prior stroke or transient ischemic attack, heart failure with preserved ejection fraction (HFpEF), heart failure with reduced ejection fraction (HFrEF), heart valve disease, coronary artery disease, chronic obstructive pulmonary disease (COPD), alcohol misuse, anemia, and smoking). Furthermore, a weighted analysis was conducted utilizing weights provided by the NIS, and multivariate logistic regression was used to calculate the odds ratio. Results A total of 29,440 patient with AF who underwent ablation were included. After propensity matching, (8,110 in obese and 8,110 in non-obese group) the baseline characteristics were not significantly different between the two groups. Obesity was independently associated with higher risk of pseudoaneurysm, hematoma, postoperative anemia, acute kidney injury, vasopressor need, mechanical ventilation, pulmonary embolism, and ischemic stroke in patients who underwent ablation for AF (Figure 1). In addition, obese group had significantly higher length of stay (median and IQR 2 [1-3] vs 2 [1-4]) and total charges (median and IQR: 131,248$ [95,303-197,784] vs 143,693$ [102,720-206728]) compared to non-obese group (p&amp;lt;0.001). However, in-hospital mortality was not significantly different between the two groups. Conclusion In patients who underwent AF ablation, obesity is associated with significantly higher risk of post-operative complications, as well as increased LOS and total hospital charges.

Outcomes of ST-Elevation Myocardial Infarction in Patients with Adrenal Insufficiency

Abstract Background Patients with adrenal insufficiency (AI) have both increased risk of cardiovascular disease and adverse outcomes with many medical emergencies. However, limited data exist specifically regarding ST elevation myocardial infarction (STEMI) in the context of AI. Methods Admissions for STEMI were identified in the 2016-2019 National Inpatient Sample. In-hospital outcomes were compared between patients with and without AI. The primary outcome was in-hospital mortality. Secondary outcomes included percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG) intervention, acute kidney injury (AKI), vasopressor use, mechanical circulatory support (MCS), mechanical ventilation, ventricular tachycardia (VT), hospital length of stay (LOS), and total charges. Multivariable regression models were used to adjust for potential confounders. Results Among 690,430 STEMI hospitalizations, 1,382 (0.2%) had a diagnosis of AI. AI was associated with higher odds of in-hospital mortality (adjusted OR [aOR] 1.51, 95% CI 1.03-2.2), lower odds of PCI (aOR 0.73, 95% CI 0.55-0.98), higher odds of CABG (aOR 2.8, 95% CI 1.89-4.2) and, AKI (aOR 2.38, 95% CI 1.72–3.3), VT (aOR 1.55, 95% CI 1.1-2.2), need for vasopressors (aOR 2.34, 95% CI 1.33-4.1), mechanical ventilation (aOR 2.11, 95% CI 1.54-2.89) and MCS (aOR 2.18, 95% CI 1.57–3.03). Patients with AI also had a longer LOS (10 days vs. 4.2 days, p&amp;lt;0.001) and higher charges ($258,475 vs. $115,505, p&amp;lt;0.001). Conclusion Patients with AI admitted for STEMI had higher in-hospital mortality, non-fatal adverse outcomes, and resource utilization compared to patients without AI.

Evaluation of a Physiologic-Driven Closed-Loop Resuscitation Algorithm in an Animal Model of Hemorrhagic Shock.

Appropriate resuscitation from hemorrhagic shock is critical to restore tissue perfusion and to avoid over-resuscitation. The objective of this study was to test the ability of a closed-loop diagnosis and resuscitation algorithm called resuscitation from shock using functional hemodynamic monitoring using invasive monitoring (ReFit1) and minimally invasive monitoring (ReFit2) to identify, treat, and stabilize a porcine model of severe hemorrhagic shock. We created a ReFit algorithm using dynamic hemodynamic parameters of pulse pressure variation (PPV), stroke volume variation (SVV), dynamic arterial elastance (Eadyn = PPV/SVV), driven by mean arterial pressure (MAP), mixed venous oxygen saturation, and heart rate targets to define the need for fluids, vasopressors, and inotropes. University-based animal laboratory. Twenty-seven female pigs. Anesthetized, intubated, and ventilated (8 mL/kg) pigs were bled at 10 mL/min until a MAP of less than 40 mm Hg, held for 30 minutes, then resuscitated. The ReFit algorithm used the above dynamic parameters to drive computer-controlled infusion pumps to deliver blood, lactated Ringer's solution, norepinephrine, and in ReFit1 dobutamine. In four animals, after initial resuscitation from hemorrhagic shock, the ability of the ReFit1 algorithm to treat acute air embolism-induced pulmonary hypertension and right heart failure was also tested. In 10 ReFit1 and 17 ReFit2 animals, the time to stabilization from shock was not dissimilar to open controlled resuscitation performed by an expert physician (52 ± 12, 50 ± 13, and 60 ± 15 min, respectively) with similar amounts of fluids and norepinephrine needed. In four ReFit1 animals after initial stabilization, the algorithm successfully resuscitated the animals after inducing an acute air embolism right heart failure, with all animals recovering stability within 30 minutes. Our physiologically based functional hemodynamic monitoring-centered closed-loop resuscitation system can effectively diagnose and treat cardiovascular shock due to hemorrhage and air embolism.

Exploration of the optimal programmed intermittent epidural bolus volume with the dural puncture epidural technique for labour analgesia: a biased-coin up-and-down sequential allocation study.

To determine the optimal programmed intermittent epidural bolus (PIEB) volume for providing effective analgesia in 90% of patients (EV90) during the first stage of labour using the dural puncture epidural (DPE) technique to initiate labour analgesia. We conducted a biased-coin up-and-down sequential allocation study. We included 40 nulliparous women requiring epidural labour analgesia. We used a 25G Whitacre spinal needle to puncture the dural mater and then administered a loading dose of 12mL of ropivacaine 0.1% and sufentanil 0.3μg·mL-1. Subsequently, the PIEB pump delivered boluses with an identical solution at a fixed 40-min interval, starting 1hr after epidural initiation. The bolus volume for the first patient was 7mL and was adjusted for subsequent patients according to the study protocol (bolus volume, 7-12mL). The primary endpoint was effective analgesia, indicated by no need for patient-controlled or manual boluses within 6hr after analgesia initiation or until complete cervical dilation, whichever came first. Outcome evaluators assessed the patients' pain ratings, Bromage scores, sensory blockade level, and maternal blood pressure hourly. Using the truncated Dixon and Mood method, the estimated EV90 was 9.2mL (95% confidence interval [CI], 8.5 to 9.9) whereas the isotonic regression method yielded a value of 8.8mL (95% CI, 8.6 to 9.8). None of the patients experienced a motor block. Two patients experienced hypotension without the need for vasopressors. The estimated PIEB EV90 for ropivacaine 0.1% and sufentanil 0.3μg·mL-1 approached 9mL when DPE was combined with a fixed 40-min interval.

Neutrophil-platelet ratio as a predictor of acute kidney injury in severe COVID-19.

Acute kidney injury (AKI) is one of the most seen complications of coronavirus-2019 (COVID-19) infection. Patients with AKI caused by COVID-19 likely have higher neutrophil counts and lower platelet and lymphocyte levels. Therefore, the predictive value of many inflammation indexes calculated from the total blood count has been investigated to predict the AKI in COVID-19. According to our clinical experience, we thought that neutrophilia and thrombocytopenia may be more common in the development of AKI. For this reason, this study aimed to evaluate the predictive value of the neutrophil-to-platelet ratio (NPR) for AKI in severe COVID-19 patients. This retrospective study included 334 severe COVID-19 patients followed up in the intensive care unit (ICU). Predictive factors for AKI were analyzed. ROC curve analysis was performed to determine the inflammation indexes' cutoff values for the AKI prediction. Multivariate analyses were performed to determine correlations between the inflammation indexes and AKI. In this study, AKI was determined at the rate of 43% (n:145). Independent risk factors affecting AKI were determined to be age (HR = 1.047, 95% confidence interval [CI]: 1.021-1.072, P < .001), the need for invasive mechanical ventilation (HR = 3.003, 95% CI: 1.645-5.481, P = .001) and the need for vasopressor (HR = 8.111, 95% CI: 3.786-17.375, P < .001). The optimal cutoff values predicting AKI were determined to be 3.9 for the NPR (AUC = 0.679, 95% CI: 0.622-0.737, P < .001) with 71.7% sensitivity and 61.9% specificity, 16.1 for the neutrophil-to-lymphocyte ratio (NLR) (AUC = 0.634, 95% CI: 0.575-0.694, P < .001) with 65.5% sensitivity and 56.1% specificity, and 3872.5 × 109L for the systemic inflammatory index (SII) (AUC = 0.566, 95% CI: 0.504-0.629, P = .038) with 60% sensitivity and 55.6% specificity. In the regression model, only NPR values above the cutoff were related to AKI (HR = 3.817, 95% CI: 1.782-8.177, P = .001). The NPR has more predictive value than the NLPR, NLR, and SII in developing AKI in severe COVID-19 patients in the ICU. NPR is a new helpful index that can help clinicians predict early AKI in critical COVID-19.

A pilot randomized controlled trial comparing noradrenaline and adrenaline as a first-line vasopressor for fluid-refractory septic shock in neonates.

Limited data exists on noradrenaline therapy in neonatal septic shock. We compared the efficacy of noradrenaline with adrenaline in neonatal septic shock. This single center, open label, pilot randomized controlled trial included neonates with clinical evidence of sepsis and shock. Primary outcomes were: 1) resolution of shock one hour after treatment, and 2) mortality during hospital stay. Secondary outcomes included: need for additional vasopressors; hemodynamic stability without further administration of vasopressors for ≥2 h; changes in blood pressure and heart rate after 1 h of vasopressor treatment; and morbidities during the hospital stay. Of 65 eligible neonates, 42 were randomized (21 each in adrenaline and noradrenaline treatment arms) between August 2020 and January 2022, at level III neonatal intensive care unit (NICU) of Bharati Vidyapeeth Deemed University Medical College and Hospital (BVDUMCH). The mean (SD) gestational age and mean (SD) birth weight were 36.1(4.2) weeks and 1.8 (0.2) kilograms birth weight for noradrenaline and 36.9 (4.1) weeks and 1.7 (0.7) kilograms for adrenaline. Shock resolved within 1 h of vasopressor therapy in 76.2% neonates in the noradrenaline arm and 61.9% in adrenaline arm (p value-0.53). Mortality during hospital stay was 28.6% (6/21) in noradrenaline group and 33.3% (7/21) in adrenaline group (p value- 0.58). Additional vasopressors were required in 23.8% neonates of the noradrenaline group compared to 38.1% neonates in adrenaline arm (p value-0.53). Median (SD) duration of intensive care stay was 6 (SD) days in the noradrenaline group and 10 (SD) days in the adrenaline group (p value-0.045). Among neonates with septic shock, the efficacy of noradrenaline was comparable to adrenaline in resolving septic shock after one hour of infusion and on the mortality during hospital stay. https://ctri.nic.in/Clinicaltrials/pmaindet2.php?EncHid=NDI2NTc=&Enc=&userName=noradrenaline, Clinical Trials Registry - India with identifier CTRI/2020/08/027185 (17/08/2020).

Comparison Of Prophylactic Effects Of Gargling Different Doses Of Ketamine On Attenuating PostOperative Sore Throat.

Aims and objectives: The aim of the study is to evaluate effectiveness of two doses of ketamine gargle in preventing post-operative sore throat (POST). Materials &amp; Method: Sixty-nine patients scheduled for elective surgery under general anaesthesia were randomized into three groups: Group C, saline 30 ml; Group A, ketamine 100 mg in Saline 30 ml and Group, ketamine 120 mg in saline 30ml. Patients were asked to gargle this mixture for 30 seconds, 5 minutes before induction of anaesthesia. POST was graded at 4, 8 and 24 hours after operation on a four-point scale (0-3). The primary outcome of incidence and grading of POST along with secondary outcomes of drug-related adverse effects were observed and recorded. Results: In the Control group POST occurred more frequently, when compared with patients belonging to both the Ketamine groups at 4, 8, and 24 hours (74%, 70%, and 52%). The greatest difference in the severity of POST was observed at the 4-hour and 8-hour intervals in both the 100 mg and 120 mg ketamine groups. However, these groups exhibited similar outcomes at the 24-hour mark (p&lt;0.05). Conclusion: Prophylactic intravenous Glycopyrrolate in spinal anesthesia for cesarean section reduces the incidence and severity of hypotension and the need for Vasopressor.

National Trends and In-Hospital Outcomes for Immediate Implant-Based Versus Autologous-Based Breast Reconstruction: A Propensity Score-Matched Analysis.

Breast reconstruction consists primarily of two methods: autologous breast reconstruction (ABR) and implant-based breast reconstruction (IBR). Each of these methods has its advantages and disadvantages. The current study used the National Inpatient Sample (NIS), the largest inpatient database in the United States, to explore the trends, complications, and disparities in the use of IBR and ABR. The current study used the NIS database from 2016 to 2020, including the International Classification of Diseases, 10th version (ICD-10) codes. A propensity score-matching (1:1) analysis was used to match the IBR and ABR groups. The percentage of breast reconstruction increased from 58.8% in 2016 to 63.4% by 2020. The trend of ABR was upward, and the trend of IBR was downward. In addition, the ABR group had significantly higher rates of cardiovascular complications (odds ratio [OR], 1.29), respiratory complications (OR, 4.26), vascular complications requiring surgery (OR, 7.82), blood transfusions (OR, 3.44), vasopressor need (OR, 1.409), and acute kidney injury (OR, 1.68). However, the ABR group had significantly lower rates of wound infection (OR, 0.430), wound dehiscence (OR, 0.213), wound seroma (OR, 0.602), and sepsis (OR, 0.252). A significant disparity was found in using ABR for different subgroups based on age, hospital teaching status, racial background, socioeconomic status, and hospital bed size. The current study showed an upward trend in the utilization of ABR and a downward trend for IBR. Although ABR had a higher rate of pulmonary, cardiovascular, vascular, and bleeding complications, it had a lower rate of wound-related complications.

The polymyxin-B direct hemoperfusion OPTimal Initiation timing with Catecholamine PMX-OPTIC study: A multicenter retrospective observational study.

Polymyxin-B direct hemoperfusion (PMX-DHP) is an endotoxin adsorption column-based blood purification therapy. Since one of the most potent effects of PMX-DHP is blood pressure elevations, it may be the most effective when it is introduced at the time when the need for vasopressors is the greatest, which, in turn, may reduce mortality. A multicenter retrospective study was conducted at 24 ICUs in Japan. In each ICU, the 20 most recent consecutive cases of septic shock treated with PMX-DHP were analyzed. The duration between the time of the peak vasopressive agent dose, expressed as the noradrenaline equivalent dose (NEq), and the time of PMX initiation was evaluated. The primary outcome was 28-day mortality, and a multivariable analysis was performed to investigate factors associated with mortality. A total of 480 septic shock patients were included in the analysis. Among all patients, the 28-day mortality group was older, more severely ill, and had a higher body mass index. The NEq peak and NEq on PMX-DHP initiation were both higher in deceased patients. Regarding the timing of PMX-DHP initiation from the NEq peak, -4 << 4 h had more survivors (229/304, 75.3%) than ≤-4 h (50/75, 66.7%) and ≥4 h (66/101, 65.4%) (p = 0.085). When -4 << 4 h was assigned as a reference, the timing of PMX-DHP initiation from the NEq peak of ≤-4 h had an odds ratio of 1.96 (1.07-3.58), p = 0.029, while ≥4 h had an odds ratio of 1.64 (0.94-2.87), p = 0.082 for 28-day mortality, in the multivariable regression analysis. A spline curve of the relationship between the probability of death and the timing of PMX-DHP initiation from the NEq peak showed a downward convex curve with a nadir at timing = 0. The odds ratios of the timing of PMX-DHP initiation other than -4 << 4 h were significantly higher in an older age, male sex, lower BMI, more severe illness, and higher oxygenation. The induction of PMX-DHP at the time of the peak vasopressor dose correlated with lower mortality. PMX-DHP is one of the options available for elevating blood pressure in septic shock, and its initiation either too early or late for shock peak may not improve the outcome.

Minimal invasive extracorporeal circulation: A bibliometric network analysis of the global scientific output.

Minimal Invasive Extracorporeal Circulation (MiECC) has recently emerged as a more 'physiologic' alternative to conventional extracorporeal circulation. However, its adoption is still limited due to lack of robust scientific evidence and ongoing debate about its potential benefits. This bibliometric analysis aims to analyze the scientific articles on MiECC and identify current research domains and existing gaps to be addressed in future studies. Pertinent articles were retrieved from the Web of Science (WOS) database. The search string included 'minimal invasive extracorporeal circulation' and its synonyms. The VOSviewer (version 1.6.17) software was used to conduct comprehensive analyses. Semantic and research networks, bibliographic coupling and journal analysis were performed. Of the 1777 articles identified in WOS, 292 were retrieved. The trend in publications increased from 1991 to date. Most articles focused on transfusion requirements, acute kidney injury, inflammatory markers and cytokines, inflammation and delirium, though the impact of intraoperative optimal fluid and hemodynamic management as far as the occurrence of postoperative complications were poorly addressed. The semantic network analysis found inter-connections between the terms "cardiopulmonary bypass", "inflammatory response", and "cardiac surgery". Perfusion contributed the highest number of published documents. The most extensive research partnerships were between Germany, Greece, Italy, and England. Notwithstanding the scientific community's growing interest in MiECC, crucial topics (i.e., the best anesthetic management and intraoperative need for inotropes, vasopressors and fluids) still require more comprehensive exploration. This investigation may prove to be a useful tool for clinicians, scientists, and students concerning global publication output and for the use of MiECC in cardiac surgery.

Comparison of 24 vs 72-hr octreotide infusion in acute esophageal variceal hemorrhage - A multi-center, randomized clinical trial

BackgroundCurrent guidelines lack clarity about the optimal duration of octreotide therapy for patients with esophageal variceal hemorrhage (EVH). To address this lack of evidence, we conducted a randomized clinical trial (RCT) of 24-hr versus 72-hr continuous infusion of octreotide for patients with EVH. MethodsThis multi-center, prospective RCT (NCT03624517), randomized patients with EVH to 24-hr versus 72-hr infusion of octreotide. Patients were required to undergo esophageal variceal band ligation prior to enrollment. The primary endpoint was rebleeding rate at 72 hr. The study was terminated early due to an inability to recruit during and after the COVID-19 epidemic. ResultsFor patients randomized to 72-hr (n = 19) of octreotide vs 24-hr (n = 15), there were no differences in the need for transfusion, average pRBC units transfused per patient (3 units vs 2 units), infection (5 % vs 0 %), mechanical ventilation (11 % vs 7 %), or the need for vasopressors (5 % vs 3 %), respectively (none of these differences were statistically significantly different). There were 2 re-bleeding events in the 72-hr group (11 %), and no re-bleeding events in the 24-hr group (p = 0.49). 8/15 of patients receiving 24 hr of octreotide were discharged at or before hospital day 3 while none in the 72-hr group was discharged before day 3 (p < 0.001). There was one death (in the 72-hr group) within 30 days. ConclusionsA 24-hr infusion is non-inferior to a 72-hr infusion of octreotide for prevention of re-bleeding in patients with EVH. We propose that shortened octreotide duration may help reduce hospital stay and related costs in these patients.

Intercambio de plasma y enfermedades autoinmunes críticas

Introduction: Renal replacement therapy (RRT) has evolved significantly since its introduction; initially used to treat acute renal failure, it is applied in various clinical scenarios due to improved membranes and equipment. Other techniques have emerged, such as therapeutic apheresis and hemoadsorption, which allow specific components to be removed from the blood. These therapies have shown promise in the treatment of various diseases. Important points: Sepsis and septic shock are the most common causes of admission to intensive care units (ICU), and extracorporeal therapies (ECT) have shown promise in their management. Sepsis is characterized by a dysregulated inflammatory response, which can lead to multiorgan damage. ECT can help modulate this response, eliminating inflammatory mediators and restoring immune balance. Although clinical evidence is inconclusive for all indications, studies have shown improvements in clinical parameters, such as decreased need for vasopressors and improved oxygenation. The response to ECT may be variable between patients due to genetic, epigenetic, and sociodemographic factors. Conclusion: extracorporeal therapies are presented as a promising tool in the management of critically ill patients, and their use is expanding beyond sepsis. As more scientific evidence accumulates, it is expected that these techniques will become consolidated as part of the standard treatment in various pathologies.

Prognostic value of PGI score compared to poison severity score (PSS) and simplified acute physiology score (SAPS) II as predictors of mortality and other adverse outcomes in acute poisoning with aluminum phosphide

Aluminum phosphide (AlP) poisoning is a life-threatening emergency prevalent in the Middle East region including Egypt. Early prediction of prognosis is critical for initiating the utmost intensive interventions. Though many scoring systems were studied for predicting the prognosis of AlP poisoning, these scores received wide criticism. Complexity and reliability were the main concerns. Therefore, this retrospective cross-sectional study aimed to evaluate the performance of the recently introduced PGI score as a predictor of case fatality, the need for mechanical ventilation and vasopressor therapy in acute AlP poisoning. Moreover, it compares the performance of PGI with the known poison severity score (PSS), and the simplified acute physiology score (SAPS) II. Among 144 exposed patients, we reported a mortality rate of 61.1%. Non-survivors exhibited significantly higher PGI, PSS, and SAPS II than survivors. Though the PGI, PSS, and SAPS II proved their significance as predictors of mortality and, the need for MV and vasopressors, the PGI score showed a significantly higher area under the curve (AUC) as a predictor of MV (AUC = 0.848) compared to PSS (AUC = 0.731) and SAPS II (AUC = 0.749). Additively, PGI of 2 or more was a significant predictor of mortality (AUC = 0.831, sensitivity = 65.9%, and specificity = 89.3 %) and MV (p < 0.001), while PGI of 1 or more was another predictor of vasopressor need (AUC = 0.881, sensitivity = 89.0% and specificity = 79.4%). Given the PGI score's high AUCs across all outcomes, coupled with its balanced sensitivity and specificity, the PGI score could be a simple, and robust tool replacing the PSS and SAPS II for predicting mortality, clinical decision-making including the need for MV and vasopressor therapy in acute AlP exposure. Adopting the PGI score seems substantially useful in managing acute AlP poisoning, notably in resource-restricted countries.

Prediction of vasopressor needs in hypotensive emergency department patients using serial arterial blood pressure data with deep learning

AbstractBackgroundShock is a life‐threatening condition that is associated with high mortality and morbidity. Therefore, the timely identification and management of this condition are important. We aimed to develop a prediction model for vasopressor use based on concise serial arterial blood pressure data.MethodsWe collected continuous arterial blood pressure from patients admitted to the emergency department (ED) resuscitation room. Patients with an initial systolic blood pressure lower than 90 mmHg were included in the study. We developed prediction models using convolutional neural networks (CNNs) and long short‐term memory (LSTM) networks. Discrimination performance was assessed using the area under the receiver operating characteristic curve (AUROC) and the area under the precision–recall curve (AUPRC).ResultsA total of 120 patients were enrolled in the study. The CNN and LSTM models yielded AUROCs ranging from 0.731 to 0.834 for predicting the need for vasopressor infusion within different time frames (30 min, 1 h, and 6 h). LSTM outperformed the CNN in terms of predicting vasopressor infusion within 30 min and 1 h (p value &lt; 0.05). The AUPRC values ranged from 0.200 to 0.252, and sensitivity–specificity analyses indicated that the models have potential for clinical applications.ConclusionThis study used serial arterial blood pressure data to construct a promising prediction model for the need for vasopressors in hypotensive ED patients. The simplicity and accuracy of the model provide valuable insights for developing a clinical decision support tool for resuscitation in emergency settings.

Feasibility of deescalating postoperative care in enhanced recovery after cardiac surgery.

Enhanced Recovery After Surgery (ERAS) prioritizes faster functional recovery after major surgery. An important aspect of postoperative ERAS is decreasing morbidity and immobility, which can result from prolonged critical care. Using current clinical data, our aim was to analyze whether a six-hour monitoring period after Minimally Invasive Cardiac Surgery (MICS) might be sufficient to recognize major postoperative complications in a future Fast Track pathway. Additionally, we sought to investigate whether it could be possible to deescalate the setting of postoperative monitoring. 358 patients received MICS and were deemed suitable for an ERAS protocol between 01/2021 and 03/2023 at our institution. Of these, 297 patients could be successfully extubated on-table, were transferred to IMC or ICU in stable condition and therefore served as study cohort. Outcomes of interest were incidence and timing of Major Adverse Cardiac Events (MACE; death, myocardial infarction requiring revascularization, stroke), bleeding requiring reexploration and Fast Track-associated complications (reintubation and readmission to ICU). Patients' median age was 63 years (IQR 55-70) and 65% were male. 189 (64%) patients received anterolateral mini-thoracotomy, primarily for mitral and/or tricuspid valve surgery (n = 177). 108 (36%) patients had partial upper sternotomy, primarily for aortic valve repair/replacement (n = 79) and aortic surgery (n = 17). 90% of patients were normotensive without need for vasopressors within 6 h postoperatively, 82% of patients were transferred to the general ward on postoperative day 1 (POD). Two (0.7%) MACE events occurred, as well as 4 (1.3%) postoperative bleeding events requiring reexploration. Of these complications, only one event occurred before transfer to the ward - all others took place on or after POD 1. There was one instance of reintubation and two of readmission to ICU. If MICS patients can be successfully extubated on-table and are hemodynamically stable, major postoperative complications were rare in our single-center experience and primarily occurred after transfer to the ward. Therefore, in well selected MICS patients with uncomplicated intraoperative course, monitoring for six hours, possibly outside of an ICU, followed by transfer to the ward appears to be a feasible theoretical concept without negative impact on patient safety.

Outcome of Subarachnoid Block with Low Dose Bupivacaine and Fentanyl for Lower Limb Vascular Surgeries in Patients with Coronary Artery Disease

Subarachnoid block (SAB) with local anesthetics and opioids (fentanyl) and able to perform spinal anesthesia because of the synergistic effects and allow top use of low dose local anesthetics which results in a stable hemodynamic state. A randomized clinical trial was conducted to observe the cardiovascular effects of subarachnoid block (SAB) with low dose bupivacaine and fentanyl on patient with coronary artery disease, between January 2021 and December 2022. A total of 36 patients who had known case of coronary artery disease. All patients underwent spinal block for lower limb surgery with 7.5 mg hyperbaric bupivacaine 0.5% and 25 µg fentanyl. In each patient, 1 mg I/V midazolam was used and if needed subsequent may be given. Complications related to anesthesia such as hypotension, bradycardia, vasopressor need, and blood or volume use were recorded. Our study shows at the 90-minutes of spinal block, patients with EF ≤40% experienced a decrease of 10.5% in systolic blood pressure, while those with EF&gt;40% experienced a larger decrease of 19%. At the 90-minutes of spinal block, percentage decrease was higher in the EF&gt;40% group (19.5% vs. 14%) in diastolic blood pressure. At the 90-minutes of spinal block, patients with EF ≤ 40% experienced a decrease of 13% in MAP, while those with EF&gt;40% experienced a larger decrease of 19%. The findings demonstrate that patients with EF&gt;40% exhibited larger percentage decreases in systolic blood pressure, diastolic blood pressure, and MAP compared to those with EF ≤40%. The difference was statically significant (P&lt;0.05). Our study recommends subarachnoid block with low dose of bupivacaine and fentanyl is effective in lower limbs surgeries for patients with coronary artery disease particularly with low EF.

Premature Closure of the Ductus Arteriosus and Veno-Arterial Extracorporeal Membrane Oxygenation in Critically Ill Neonates: A 10-Year Single-Center Retrospective Study.

To describe critically ill neonates with premature closure of the ductus arteriosus (DA) and assess the frequency as well as predictive factors for extracorporeal membrane oxygenation (ECMO) support in the latter. This was a monocentric retrospective observational study conducted in the NICU of a French academic medical center between 01/01/2013 and 01/01/2023. All neonates diagnosed with premature closure of the DA were included. Exclusion criteria were associated congenital heart disease amenable to urgent surgeryor contraindication for ECMO. Eleven neonates with complete premature closure of the DA were included. Births were full-term with a weight of 3.60kg [3.16-3.89]. Only one case (9%) was diagnosed antenatally. Premature closure of the DA was idiopathic in seven neonates (64%) and associatedto maternal exposure to non-steroidal anti-inflammatory drugs (NSAIDs) in three (27%). All newborns had pulmonary hypertension (PH) and right ventricular hypertrophy. Three neonates (27%) were supported on veno-arterial ECMO and appeared to have more pathological adaptation to extra-uterine life, greater need for vasopressor and/or inotropic support, and higher frequency of bi-ventricular failure (100%) or morphological anomaly of the tricuspid valve (67%). No patient died but more than half had non-cardiological sequelae. Veno-arterial ECMO support is not uncommon in critically ill neonates with premature DA closure and appeared to be associated with more pathological adaptation to extra-uterine life, greater need for vasoactive-inotropic support and higher frequency of bi-ventricular failure or morphological anomaly of the tricuspid valve. These parameters can help clinicians to identify neonates likely to require such an assistance.

Evaluation of the effect of the quality and quantity of fluid drained due to pleural effusion on complications that may develop in intensive care unit

Aims: Pleural drainage volume is very important for oxygenation and perfusion in patients with massive pleural effusion. However, there is still no clear data between the complications that may develop after pleural drainage and the optimal volume of fluid to be removed. The primary aim of this study was to evaluate the effect of the quality and quantity of pleural fluid drained due to pleural effusion in the intensive care unit (ICU) on the complications that may develop after drainage and to determine the optimal drainage volume to prevent complications. The secondary aim was to determine the risk factors affecting the development of complications after pleural effusion drainage. Methods: A total of 176 patients who underwent pleural drainage for pleural effusion between April 1,2022 and December 31,2023 in an adult tertiary ICU were retrospectively analyzed. Demographic information, clinical follow-up information, quantity and quality of pleural effusion, laboratory values and complications were recorded and the relationship between these parameters and the amount of pleural fluid drained within 24 hours and complications were evaluated. Results: ICU duration, ICU mortality, activated partial thromboplastin time (aPTT) and vasopressor requirement were found to be statistically significantly higher in patients with complications after pleural drainage procedure. In multivariate logistic regression analysis, female gender (odds ratio=0.455, p=0.049) and need for vasopressors (odds ratio=2.373, p=0.034) increased the risk of complications. There was no statistically significant difference between the amount of pleural fluid drained and complications. In addition, when the optimal amount of drained fluid required to prevent complications was analyzed, a cut off value could not be given. Conclusion: In order to reduce the risk of complications that may develop after pleural drainage, we believe that paying more attention to the position during pleural drainage in patients receiving vasopressor support and performing pleural drainage with the help of ultrasound in patients whose position cannot be changed due to hemodynamic disorder will reduce the complication rate. We think that a decrease in the complication rate will be effective in terms of both cost and efficient use of ICU beds by reducing the length of ICU stay and ICU mortality. In our study, the quality and quantity of pleural fluid drained had no effect on the complications that may develop after drainage, and further studies with a larger patient population are needed to investigate this situation.
