RESUMEN

BACKGROUND: Sepsis is a life-threatening organ dysfunction caused by an excessive host response to infection, manifested by elevated levels of inflammatory cytokines. At present, the use of hemoperfusion to remove inflammatory cytokines from the bloodstream has been expanding. Meanwhile, the pharmacokinetics and pharmacodynamics characteristics of antibiotics in critically ill patients may be impacted by hemoperfusion. CASE PRESENTATION: The patient was a 69-year-old male with poorly controlled type 2 diabetes. When admitted to the ICU, Multiple Organ Dysfunction Syndrome (MODS) appeared within 48 h, and he was suspected of septic shock due to acute granulocytopenia and significantly increased procalcitonin. Broad-spectrum antibiotics imipenem was administered according to Sepsis 3.0 bundle and hemoperfusion lasting 4 h with a neutron-macroporous resin device (HA-380, Jafron, China) five times was conducted to lower the extremely high value of serum inflammatory factors. Blood samples were collected to measure imipenem plasma concentration to investigate the effect of hemoperfusion quantitatively. This study showed that 4 h of hemoperfusion had a good adsorption ability on inflammatory factors and could remove about 75.2% of imipenem. CONCLUSIONS: This case demonstrated the high adsorption capacity of hemoperfusion on imipenem in critically ill patients. It implies a timely imipenem supplement is required, especially before hemoperfusion.

RESUMEN

BACKGROUND: The selection of adequate indicators of tissue hypoxia for guiding the resuscitation process of septic patients is a highly relevant issue. Current guidelines advocate for the use of lactate as sole metabolic marker, which may be markedly limited, and the integration of different variables seems more adequate. In this study, we explored the metabolic profile and its implications in the response to the administration of a fluid challenge in early septic shock patients. METHODS: Observational study including septic shock patients within 24 h of ICU admission, monitored with a cardiac output estimation system, with ongoing resuscitation. Hemodynamic and metabolic variables were measured before and after a fluid challenge (FC). A two-step cluster analysis was used to define the baseline metabolic profile, including lactate, central venous oxygen saturation (ScvO2), central venous-to-arterial carbon dioxide difference (PcvaCO2), and PcvaCO2 corrected by the difference in arterial-to-venous oxygen content (PcvaCO2/CavO2). RESULTS: Seventy-seven fluid challenges were analyzed. Cluster analysis revealed two distinct metabolic profiles at baseline. Cluster A exhibited lower ScvO2, higher PcvaCO2, and lower PcvaCO2/CavO2. Increases in cardiac output (CO) were associated with increases in VO2 exclusively in cluster A. Baseline isolated metabolic variables did not correlate with VO2 response, and changes in ScvO2 and PcvaCO2 were associated to VO2 increase only in cluster A. CONCLUSIONS: In a population of early septic shock patients, two distinct metabolic profiles were identified, suggesting tissue hypoxia or dysoxia. Integrating metabolic variables enhances the ability to detect those patients whose VO2 might increase as results of fluid administration.

RESUMEN

INTRODUCTION: Sepsis often leads to acute kidney injury (AKI), presenting significant challenges in fluid management. This study explores the potential of analyzing intrarenal venous flow (IRVF) patterns to guide tailored fluid therapy, aiming to improve patient outcomes. PATIENT CONCERNS: A patient was admitted to the intensive care unit with symptoms of septic shock, including fever, severe hypotension, and altered mental status, secondary to a perforated ascending colon adenocarcinoma. DIAGNOSIS: The patient was diagnosed with perforated ascending colon adenocarcinoma, septic shock, and AKI. Clinical findings included elevated inflammatory markers and impaired renal function. INTERVENTIONS: The primary therapeutic interventions included surgical resection of the perforated colon, administration of broad-spectrum antibiotics, and fluid resuscitation. Fluid management was guided by continuous monitoring of IRVF, which facilitated precise adjustments to optimize fluid balance and renal perfusion. OUTCOMES: By utilizing IRVF patterns to guide fluid therapy, the patient's circulatory status and renal function significantly improved. The individualized fluid management approach contributed to better stabilization of the patient's condition. LESSONS: This case underscores the potential utility of IRVF patterns in guiding fluid management strategies for patients with sepsis and AKI. The main is the benefit of IRVF-guided fluid therapy in improving patient outcomes. Further research is warranted to validate the efficacy and safety of this approach, with the aim of enhancing clinical outcomes in critically ill patients.

RESUMEN

Erythroderma is characterized by diffuse erythema and scale covering over 90% body surface area that can affect individuals with inflammatory dermatoses such as psoriasis. Complications of erythrodermic psoriasis include infection and cardiovascular compromise. Here we present a case of a 68 year-old man who was hospitalized for erythrodermic psoriasis refractory to multiple immunosuppressive and immunomodulatory therapies, ultimately developing sepsis due to bacteremia and fungemia complicated by infective endocarditis and a mycotic aneurysm. Although the widespread loss of epidermal function in erythroderma increases the risk of infection by opportunistic pathogens, water loss, and electrolyte imbalances, there are very few reported cases of psoriatic erythroderma complicated by fungemia and mycotic aneurysm. Given the high mortality associated with widespread epidermal dysfunction, there is a great need for evidence-based treatment guidelines for psoriatic erythroderma.

RESUMEN

BACKGROUND AND OBJECTIVE: Renal replacement therapy (RRT) plays a critical role in antimicrobial removal, particularly for low-molecular-weight drugs with low plasma protein binding, low distribution volume and hydrophilicity. Medium cut-off (MCO) membranes represent a new generation in dialysis technology, enhancing diffusive modality efficacy and increasing the cut-off from 30 to 45 kDa, crucial for middle molecule removal. This monocentric randomized crossover pilot study aimed to evaluate the impact of continuous haemodialysis with MCO membrane (MCO-CVVHD) on the removal of piperacillin, tazobactam and meropenem compared with continuous veno-venous hemodiafiltration with standard high-flux membrane (HFM-CVVHDF). METHODS: Twenty patients were randomized to undergo MCO-CVVHD followed by HFM-CVVHDF or vice versa. Extraction ratio (ER), effluent clearance (Cleff) and treatment efficiency were assessed at various intervals. Antibiotic nadir plasma levels were measured for both treatment days. RESULTS: HFM-CVVHDF showed greater ER compared with MCO-CVVHD for meropenem (ß = - 8.90 (95% CI - 12.9 to - 4.87), p < 0.001) and tazobactam (ß = - 8.29 (95% CI - 13.5 to - 3.08), p = 0.002) and Cleff for each antibiotic (meropenem ß = - 10,206 (95% CI - 14,787 to - 5787), p = 0.001); tazobactam (ß = - 4551 (95% CI - 7781 to - 1322), p = 0.012); piperacillin (ß = - 3913 (95% CI - 6388 to - 1437), p = 0.002), even if the carryover effect influenced the Cleff for meropenem and tazobactam. No difference was observed in nadir plasma concentrations or efficiency for any antibiotic. Piperacillin (ß = - 38.1 (95% CI - 47.9 to - 28.3), p < 0.001) and tazobactam (ß = - 4.45 (95% CI - 6.17 to - 2.72), p < 0.001) showed lower nadir plasma concentrations the second day compared with the first day, regardless the filter type. CONCLUSION: MCO demonstrated comparable in vivo removal of piperacillin, tazobactam and meropenem to HFM.

RESUMEN

MEDICAL HISTORY: A 25-year-old female outpatient presenting with fever and micro-hematuria was treated for urinary tract infection. Her condition worsened over 3 days at home. After experiencing multiple falls caused by leg weakness and mental confusion, she was admitted to a hospital with high fever. DIAGNOSTICS: Initial laboratory findings showed hemolytic anemia, pancytopenia, and acute kidney injury, suggesting hemolytic uremic syndrome. However, a detailed fever evaluation revealed her recent return from Afrika. This prompted a malaria test, which confirmed Plasmodium falciparum infection with 80 % parasitemia. THERAPY AND PROGRESS: Despite the quick reduction of parasitemia following treatment with intravenous administered artesunate and oral Artemether-Lumefantrine, her condition worsened, leading to a septic shock. This required renal replacement and kinetic ventilation therapy, as well as blood transfusions due to persistent hemolysis until the laboratory values normalized after 48 days post-admission. CONCLUSION: The evaluation of fever is often challenging, but most often a detailed patient history is key to early diagnosis and treatment preventing deathly outcomes in severe cases.

RESUMEN

Early diagnosis and prompt management are essential to enhance the outcomes of patients with sepsis and septic shock. Over the past two decades, evidence-based guidelines have guided appropriate treatment and recommended the implementation of a bundle strategy to deliver fundamental treatments within the initial hours of care. Shortly after its introduction, the implementation of a bundle strategy has led to a substantial decrease in mortality rates across various health care settings. The primary advantage of these bundles is their universality, making them applicable to all patients with sepsis. However, this same quality also represents their primary disadvantage as it fails to account for the significant heterogeneity within the septic patient population. Recently, the individualization of treatments included in the bundle has been suggested as a potential strategy for further improving the prognosis of patients with sepsis. New strategies for the early identification of microorganisms and their resistance patterns, advanced knowledge of antibiotic kinetics in critically ill patients, more conservative fluid therapy in specific patient populations, and early use of alternative vasopressors to catecholamines, as well as tailored source control based on patient conditions and site of infection, are potential approaches to personalize initial care for specific subgroups of patients. These innovative methodologies have the potential to improve the management of septic shock. However, their implementation in clinical practice should be guided by solid evidence. Therefore, it is imperative that future research evaluate the safety, efficacy, and cost-effectiveness of these strategies.

RESUMEN

Sepsis, one of the leading causes of death, is still lacking specific treatment. OXIRIS (BAXTER, Deerfield, IL, USA) is the first device allowing combined removal of endotoxins, inflammatory mediators and uremic toxins, alongside fluid balance control. Available data is very limited. This retrospective propensity score-matched cohort study of adult patients with septic shock aimed to evaluate septic shock duration and mortality in patients treated with either standard of care renal replacement therapy (RRT) or RRT with combined hemoadsorption, who were admitted to the interdisciplinary surgical intensive care unit at Heidelberg University Hospital during the years 2018 through 2021. Main outcomes were duration of shock, thirty-day mortality and plasma interleukin-6 levels before and after initiation of hemoadsorption. Included were 117 patients (female, 33%; male 67%); median age: 67 (16) years. After matching: 42 patients (female, 33%; male, 67%); mean age: 59.1 ± 13.8 years. There was no statistically significant difference in septic shock duration (p = 0.94; hazard ratio (HR) 0.97 (95% CI, 0.48-1.97)). Thirty-day survival analysis showed a non-statistically significant survival difference. (p = 0.063; HR 0.43 (95% CI, 0.17-1.09)). A post-hoc 90-day survival analysis revealed statistically significant longer survival and lower death hazard ratio in patients treated with RRT + HA (p = 0.037; HR = 0.42 (95% CI, 0.18-0.99). In conclusion, RRT with combined hemoadsorption of endotoxins, inflammatory mediators and uremic toxins is a modality worth further investigation.

RESUMEN

Introduction: Shock is a life-threatening condition amongst hospitalized patients and requires urgent management to avoid mortality. Early exposure is vital for educational and patient safety purposes. Methods: We developed a 90-minute shock day session that provided internal medicine interns with a cognitive framework for the initial diagnosis and management of shock, which they applied to two simulations. The first simulation involved a patient with septic shock, and the second involved a patient with cardiogenic shock. Critical action checklists were used to assess learners and guide structured debriefs after each simulation. Medical decision-making and communication frameworks were presented through a presession video and a chalk talk. The curriculum was evaluated using pre- and postintervention surveys to assess knowledge and confidence. Results: Forty-eight interns participated in the session in 2022 and 2023. We observed an increase in the percentage of learners correctly answering a knowledge-based question regarding the amount of fluid administered to a patient in septic shock (pre: 33%, post: 62%, p < .01), as well as increases in learner-reported confidence in leading a rapid response (pre: 9%, post: 62%) and in managing undifferentiated shock (pre: 13%, post: 56%), septic shock (pre: 20%, post: 83%), cardiogenic shock (pre: 2%, post: 54%), hemorrhagic shock (pre: 20%, post: 73%), and anaphylactic shock (pre: 22%, post: 54%, all ps < .01). Discussion: Employing a variety of pedagogical methods, we demonstrated that intern knowledge and confidence regarding the management of a hypotensive patient during a rapid response can be increased through participation in our curriculum.

RESUMEN

OBJECTIVE: This study aims to assess compliance with medical protocols and outcomes, as well as determine the consistency in clinical practice across different Pediatric Emergency Departments (PED) in public sector hospitals of a low-middle income country. METHODS: A retrospective analysis was conducted on patients presenting to PEDs of five public sector hospitals, namely Civil Hospital Karachi (PED 1), National Institute of Child Health (PED 2), Abbasi Shaheed Hospital (PED 3), Sheikh Zayed Hospital Larkana (PED 4), and Ghulam Muhammad Mahar College Hospital Sukkur (PED 5). The analysis covered a three-month period from February 1, 2023, to April 30, 2023. Patients diagnosed with Acute asthma, Sepsis, and Septic Shock during the study duration were included. Outcomes for each disease were evaluated based on compliance with standardized protocols.The statistical significance of data was measured by adding the p values. RESULTS: 110,450 patients visited PED during the study period and mortality rate was 2% (n=2193). 12% (13,240) were diagnosed with the three diseases during the study period. Sepsis was on top (74%, n=9,751), followed by Septic Shock (14%, n=1898), and Acute Asthma (12%, n=1591). The overall compliance rate for the three diseases was 77% (n = 10,240). Adherence to standard protocols were 98% (n = 1561) for acute asthma, 85% (n = 8240) for Sepsis, and 23% (n = 439) for Septic Shock across the five emergency departments. Of the patients who were managed according to standard protocol, 31% (n = 3135) were discharged, 30% (n- 3094) were admitted, 11% (n = 1151) were referred, 15% (n = 1501) left against medical advice and 13% (n = 1359) did not survive. On the other hand, in patients where there was noncompliance to standard protocols, 27% (n = 805) did not survive, 27% (n = 807) were discharged, 24% (n = 710) were admitted, 8% (n = 260) were referred and 14% (n = 418) left against medical advice. The differences in adherence rates among the three diseases were statistically significant (p < 0.001). CONCLUSION: The overall mortality rate was 2% in these five emergency departments and the medical protocol was followed in every third patient out of fourth in those three diseases. The survival rate till ED disposition was doubled in those patients for whom medical protocols were followed as compared to those for non-compliant. The majority of PED demonstrated good compliance with standardized practices. However, this study identified areas that require attention and further training, especially early recognition and management of septic shock where compliances seem alarmingly low. Our data analysis indicates that adherence to guidelines has resulted in uniformity in clinical practice and the provision of early evidence-based quality care. Nevertheless, there is still room for improvement in ensuring consistent adherence to medical protocols in pediatric emergency settings and thus improving patient outcomes.

RESUMEN

BACKGROUND: Sepsis is a leading cause of mortality in intensive care units and vasoactive drugs are widely used in septic patients. The cardiovascular response of septic shock patients during resuscitation therapies and the relationship of the cardiovascular response and clinical outcome has not been clearly described. METHODS: We included adult patients admitted to the ICU with sepsis from Peking Union Medical College Hospital (internal), Medical Information Mart for Intensive Care IV (MIMIC-IV) and eICU Collaborative Research Database (eICU-CRD). The Blood Pressure Response Index (BPRI) was defined as the ratio between the mean arterial pressure and the vasoactive-inotropic score. BRRI was compared with existing risk scores on predicting in-hospital death. The relationship between BPRI and in-hospital mortality was calculated. A XGBoost's machine learning model identified the features that influence short-term changes in BPRI. FINDINGS: There were 2139, 9455, and 4202 patients in the internal, MIMIC-IV and eICU-CRD cohorts, respectively. BPRI had a better AUROC for predicting in-hospital mortality than SOFA (0.78 vs. 0.73, p = 0.01) and APS (0.78 vs. 0.74, p = 0.03) in the internal cohort. The estimated odds ratio for death per unit decrease in BPRI was 1.32 (95% CI 1.20-1.45) when BPRI was below 7.1 vs. 0.99 (95% CI 0.97-1.01) when BPRI was above 7.1 in the internal cohort; similar relationships were found in MIMIC-IV and eICU-CRD. Respiratory support and latest cumulative 12-h fluid balance were intervention-related features influencing BPRI. INTERPRETATION: BPRI is an easy, rapid, precise indicator of the response of patients with septic shock to vasoactive drugs. It is a comparable and even better predictor of prognosis than SOFA and APS in sepsis and it is simpler and more convenient in use. The application of BPRI could help clinicians identify potentially at-risk patients and provide clues for treatment.

RESUMEN

OBJECTIVES: Hypothermia is associated with poor outcomes in sepsis patients, and hypothermic sepsis patients exhibit temperature alterations during initial treatment. The objective of this study was to classify hypothermic sepsis patients based on body temperature trajectories and investigate the associations of these patients with 28-day mortality. METHODS: This was a retrospective analysis of prospectively collected data from adult sepsis or septic shock patients who visited three emergency departments between August 2014 and December 2019. Hypothermic sepsis was defined as an initial body temperature <36 °C. delta temperature was calculated by subtracting the 0 h body temperature from the 6 h body temperature. We divided the patients into three groups according to delta temperature: Group A (delta temperature ≤ 0), Group B (0 < delta temperature ≤ 1) and Group C (delta temperature > 1). The primary outcome was 28-day mortality, and a multivariable Cox proportional hazards regression model was generated. RESULTS: Among 7344 patients with sepsis or septic shock, 325 hypothermic patients were included in the analysis, and the overall mortality rate was 36%. While initial body temperature was not different between survivors and nonsurvivors, survivors exhibited a higher body temperature at 6 h. The 28-day mortality rates for Groups A, B and C were 53.1%, 36.0%, and 30.0%, respectively, and Group A had significantly higher mortality than Group C did (p < 0.05). Group C demonstrated a 44.2% decrease in 28-day mortality compared to Group A (adjusted hazard ratio of 0.558; 95% confidence interval of 0.330-0.941). CONCLUSIONS: In hypothermic sepsis patients, an increase of 1 °C or more in body temperature after the initial 6 h is associated with a reduced risk of 28-day mortality.

RESUMEN

Leaving university I started working for the Belgian National Radio as a journalist. I used to travel a lot and produce radio features about life abroad and how people all over the world dealt with the different challenges in society. A privileged job that I enjoyed doing for many years. In the meantime, I got married and became a mother of two sons. Nothing to worry about, so it seemed, until January 30, 2009. I had been fighting the symptoms of flu for some days. Instead of recovering, I began to feel worse and worse: I had a high fever, was asleep most of the time, could barely eat or drink, and had to cough a lot. The general practitioner sent me to hospital. A few hours later, I had to be reanimated. It was a close call: I was infected by the Streptococcus pyogenes bacteria. My blood started thickening, my organs stopped functioning, and I went into a septic shock, followed by a cardiac arrest. I was successfully reanimated, but still not stable. For 10 days, I was fighting to survive at the intensive care unit (ICU), with several cardiac arrests and reanimations, some of which were long-lasting. The Head of the ICU informed my husband that there was less than 5% chance to survive and if so, he could not predict what kind of damage there would be: the amount of drugs that I had been given, including noradrenaline, was so extremely high, that it became very unclear how my body would respond to it. And if, as by miracle, I would survive: what kind of damage would there be? Physical? Mental? Physical and mental? No specialist could answer those questions. But both the health care professionals and my family fought to keep me alive.

RESUMEN

OBJECTIVE: To analyse the preva lence of complications related to out-of-hospital cardiac arrest patients achieving target temperature management within 360 minutes compared to those taking more than 360 minutes. METHODS: The retrospective study was conducted at a medical centre in Taiwan, and comprised data from Januar y 1, 2014, to December 31, 2020. Data was retrieved using the International Classification of Diseases version 10 codes I46.2, I46.8 and I46.9 related to adult patients of either gender presenting to the Emergenc y Medicine department with out-of-hospital cardiac arrest. Data included gender, age, medical histor y, body mass index, acute physiology and chronic health evaluation II score, blood glucose levels, electrocardiogram results, and complications occurring within the target temperature management timeframe. Data was divided into group A having patients who achieved target temperature management within 360 minutes, and group B having patients with delayed TTM of more than 360 minutes. Data was analysed using SPSS 22. RESULTS: Of the 127 patients, 76(59%) were males, 51(41%) were females,, 47(37%) were aged >75 years, and 13(10.3%) were aged <50 years. Of the total, 65(51.2%) patients were in group A, and 62(48.8%) were in group B. Pneumonia, urinary tract infection, septic shock and gastrointestinal bleeding had lower incidence rates in group A than group B (p<0.05). The odds of death were 2.879 times high er in group B patients than group A (95% confidence interval: 1.908-8.916). CONCLUSIONS: Hypothermia tre atment should be sta rted as soon as pos sible to achieve target temp erature management within 360 minutes to reduce the risk of complications and mortality.

RESUMEN

Despite significant efforts toward improving therapy for septic shock, mortality remains high. Applying veno-arterial (V-A) extracorporeal membrane oxygenation (ECMO) in this context remains controversial. Since the cannulation of the femoral artery for V-A ECMO return leads to lower body hyperoxia, this study investigated the impact of V-A ECMO therapy on the intestinal and hepatic microcirculation during septic shock in a rodent model. Thirty male Lewis rats were randomly assigned to receive V-A ECMO therapy with low (60 mL/kg/min) or high (90 mL/kg/min) blood flow or a sham procedure. Hemodynamic data were collected through a pressure-volume catheter in the left ventricle and a catheter in the lateral tail artery. Septic shock was induced by intravenous administration of lipopolysaccharide (1 mg/kg). The rats received lung-protective ventilation during V-A ECMO therapy. The hepatic and intestinal microcirculation was measured by micro-lightguide spectrophotometry after median laparotomy for two hours. Systemic and pulmonary inflammation was detected via enzyme-linked immunosorbent assays (ELISA) of the plasma and bronchoalveolar lavage (BAL), respectively, measuring tumor necrosis factor-alpha (TNF-α), interleukins 6 (IL-6) and 10 (IL-10), and C-X-C motif ligands 2 (CXCL2) and 5 (CXCL5). Oxygen saturation and relative hemoglobin concentration were reduced in the hepatic and intestinal microcirculation during V-A ECMO therapy, independent of the blood flow rate. Further, rats treated with V-A ECMO therapy also presented elevated systolic, diastolic, and mean arterial blood pressure and increased stroke volume, cardiac output, and left ventricular end-diastolic volume. However, left ventricular end-diastolic pressure was only elevated during high-flow V-A ECMO therapy. Blood gas analysis revealed a dilutional anemia during V-A ECMO therapy. ELISA analysis showed an elevated plasma CXCL2 concentration only during high-flow V-A ECMO therapy and elevated BAL CXCL2 and CXCL5 concentrations only during low-flow V-A ECMO therapy. Rats undergoing V-A ECMO therapy exhibited impaired microcirculation of the intestine and liver during septic shock despite increased blood pressure and cardiac output. Increased pulmonary inflammation was detected only during low-flow V-A ECMO therapy in septic shock.

RESUMEN

INTRODUCTION: Severe septic cardiomyopathy (SCM) is one of the main causes of refractory septic shock (RSS), with a high mortality. The application of venoarterial extracorporeal membrane oxygenation (ECMO) to support the impaired cardiac function in patients with septic shock remains controversial. Moreover, no prospective studies have been taken to address whether venoarterial ECMO treatment could improve the outcome of patients with sepsis-induced cardiogenic shock. The objective of this study is to assess whether venoarterial ECMO treatment can improve the 30-day survival rate of patients with sepsis-induced refractory cardiogenic shock. METHODS AND ANALYSIS: ExtraCorporeal Membrane Oxygenation in the therapy for REfractory Septic shock with Cardiac function Under Estimated is a prospective, multicentre, non-randomised, cohort study on the application of ECMO in SCM. At least 64 patients with SCM and RSS will be enrolled in an estimated ratio of 1:1.5. Participants taking venoarterial ECMO during the period of study are referred to as cohort 1, and patients receiving only conventional therapy without ECMO belong to cohort 2. The primary outcome is survival in a 30-day follow-up period. Other end points include survival to intensive care unit (ICU) discharge, hospital survival, 6-month survival, quality of life for long-term survival (EQ-5D score), successful rate of ECMO weaning, long-term survivors' cardiac function, the number of days alive without continuous renal replacement therapy, mechanical ventilation and vasopressor, ICU and hospital length of stay, the rate of complications potentially related to ECMO treatment. ETHICS AND DISSEMINATION: The trial has been approved by the Clinical Research and Application Institutional Review Board of the Second Affiliated Hospital of Guangzhou Medical University (2020-hs-51). Participants will be screened and enrolled from ICU patients with septic shock by clinicians, with no public advertisement for recruitment. Results will be disseminated in research journals and through conference presentations. TRIAL REGISTRATION NUMBER: NCT05184296.

RESUMEN

This study aimed to evaluate the current evidence on various aspects of fluid therapy such as type, volume, and timing of fluid bolus administration in children with septic shock. Systematic review and meta-analysis of clinical trials including children less than 18 years of age admitted to the pediatric emergency and intensive care unit with severe infection and shock requiring fluid resuscitation. The intervention included balanced crystalloids (BC) vs normal saline (NS), colloids vs NS, restricted vs liberal fluid bolus, and slow vs fast fluid bolus. The primary outcome was mortality rate. Of the 219 citations retrieved, 12 trials (3526 children with severe infection with or without malaria and shock) were included. The pooled results found no significant difference in the mortality rate between groups comparing balanced crystalloids (BC) vs normal saline (NS), colloids vs NS, restricted vs liberal fluid bolus, and slow vs fast fluid bolus. The risk of acute kidney injury (AKI) was significantly less in the BC group compared to the NS group. The certainty of evidence for mortality was of "moderate certainty" in the BC vs NS group, and was of "very low certainty" for the other two groups. CONCLUSIONS: The current meta-analysis found no significant difference in the mortality rate between the types of resuscitation fluid, and their speed or volume of administration. However, a significantly decreased risk of AKI was found in the BC group. More evidence is needed regarding the speed and volume of administration of fluid boluses in critically ill children.Prospero registration: CRD42020209066. WHAT IS KNOWN: • Balanced crystalloids (BC) may be better than normal saline (NS) for fluid resuscitation in critically ill children. WHAT IS NEW: • BC are better than NS for fluid resuscitation in critically ill children as they decrease AKI and hyperchloremia.

RESUMEN

BACKGROUND: The aim of this study was to investigate the optimal CVP range in sepsis and septic shock patients admitted to intensive care unit. METHODS: We performed a retrospective study with adult sepsis patients with CVP records based on the eICU Collaborative Research Database. Multivariable logistic regression was performed to explore the associations between CVP level and hospital mortality. Non-linear correlations and optimal CVP range were explored using restricted cubic splines (RCS). RESULTS: A total of 5302 sepsis patients were included in this study. Patients in 4-8 mmHg group owned the lowest odds ratio for raw hospital mortality (19.7%). The logistic regression analyses revealed that hospital death risk increased significantly when mean CVP level exceeds 12 mmHg compared to 4-8 mmHg level. U-shaped association of CVP with hospital mortality was revealed by RCS model in septic shock patients and the optimal range was 5.6-12 mmHg. While, there was a J-shaped trend for non-septic shock patients. For non-septic shock patients, patients had an increased risk of hospital death only if CVP exceeded 11 mmHg. CONCLUSIONS: We observed U-shaped association between mean CVP level and hospital mortality in septic shock patients and J-shaped association in non-septic shock patients. This may imply that patients with different severity of sepsis have different CVP requirements. We need to monitor and manage CVP according to the circulatory status of the sepsis patient.
