ABSTRACT

Las duplicaciones del tracto alimentario son un conjunto heterogéneo de anomalías congénitas del tubo digestivo. Su forma de presentación es variada, y pueden desarrollar distintas complicaciones libradas a su evolución natural. La infección es una complicación poco frecuente, pero que no puede desconocerse por la gravedad que implica. Se presenta el caso de una paciente de 2 años de edad, previamente sana, con una complicación atípica de una duplicación del tracto alimentario: un shock séptico. Consultó inicialmente por distensión y dolor abdominal asociado a una masa abdominal palpable. Los estudios imagenológicos evidenciaron una formación líquida parcialmente tabicada en el hemiabdomen derecho. Durante la internación, se presentó una infección intratumoral, que evolucionó al shock séptico. Respondió favorablemente al tratamiento médico del shock, y se realizó la exéresis quirúrgica posteriormente. La anatomía patológica confirmó la duplicación del tracto alimentario.


Alimentary tract duplications are heterogenous congenital anomalies of the digestive tract. Their form of presentation is varied, and they may lead to different complications, depending on their natural course. Infection is a rare complication, but it cannot be ignored because of its severity. Here we describe the case of an otherwise healthy 2-year-old girl with an atypical complication of alimentary tract duplication: septic shock. She initially consulted due to abdominal distension and pain associated with a palpable abdominal mass. The imaging studies showed a partial fluid septation in the right side of the abdomen. During hospitalization, an intratumoral infection developed, which progressed to septic shock. The patient responded favorably to medical treatment for shock, and surgical resection was subsequently performed. The pathology report confirmed the presence of alimentary tract duplication.

ABSTRACT

La sepsis es un problema global de salud y la progresión hacia el shock séptico se asocia con un incremento marcado de la morbimortalidad. En este escenario, el aumento del lactato plasmático demostró ser un indicador de gravedad y un predictor de mortalidad, y suele interpretarse casi exclusivamente como marcador de baja perfusión tisular. Sin embargo, últimamente se produjo un cambio de paradigma en la exégesis del metabolismo y propiedades biológicas del lactato. En efecto, la adaptación metabólica al estrés, aun con adecuado aporte de oxígeno, puede justificar la elevación del lactato circulante. Asimismo, otras consecuencias fisiopatológicas de la sepsis, como la disfunción mitocondrial, se asocian con el desarrollo de hiperlactatemia sin que necesariamente se acompañen de baja perfusión tisular. Interpretar el origen y la función del lactato puede resultar de suma utilidad clínica en la sepsis, especialmente cuando sus niveles circulantes fundamentan las medidas de reanimación.


Sepsis is a global health problem; progression to septic shock is associated with a marked increase in morbidity and mortality. In this setting, increased plasma lactate levels demonstrated to be an indicator of severity and a predictor of mortality, and are usually interpreted almost exclusively as a marker of low tissue perfusion. However, a recent paradigm shift has occurred in the exegesis of lactate metabolism and its biological properties. Indeed, metabolic adaptation to stress, even with an adequate oxygen supply, may account for high circulating lactate levels. Likewise, other pathophysiological consequences of sepsis, such as mitochondrial dysfunction, are associated with the development of hyperlactatemia, which is not necessarily accompanied by low tissue perfusion. Interpreting the origin and function of lactate may be of great clinical utility in sepsis, especially when circulating lactate levels are the basis for resuscitative measures.

ABSTRACT

Objective To evaluate the efficacy of vitamin C intravenous injection in the treatment of patients with sepsis.Methods PubMed,Embase,Scopus,Cochrane Library,and Clinical Trial databases were retrieved,with a retrieval period from database establishment to December 2022.English literatures on randomized controlled trial(RCT)of vitamin C intravenous injection for the treatment of sepsis or septic shock were collected.Meta-analysis was conducted using RevMan 5.3 software and Stata 15.0 software after literature screening,extraction,and evalua-tion of the bias risk included in the studies by two researchers independently.Results A total of 16 RCT studies involving 3 301 patients were included in the analysis.In terms of main outcomes,the 28-day mortality of patients in the vitamin C treatment group was slightly lower than that of the control group,but the difference was not statis-tically significant(RR=0.86,95%CI[0.72-1.03],P=0.10;I2=44%,P=0.10).In terms of secondary out-comes,vitamin C intravenous injection can reduce the duration of vasoactive drug usage time(MD=-23.44,95%CI[-30.53--16.35],P<0.01;I2=0,P=0.97),but has no significant effect on the 90-day mortality,inten-sive care unit mortality,hospital mortality,duration of mechanical ventilation,difference in estimated sequential organ failure assessment score at 72 hour,length of stay in ICU,and total length of hospital stay of patients(P>0.05).Conclusion Intravenous vitamin C injection can significantly reduce vasoactive drug usage time,but the available evidence is insufficient to support that intravenous vitamin C can improve the prognosis of patients with sepsis or septic shock.More high-quality,multicenter randomized controlled trial is needed to provide more substantial evidence about the efficacy of vitamin C in treating sepsis or septic shock.

ABSTRACT

The main clinical research advances of critical care in 2023 includes: new trials of Chinese herbal medicine, hydroxocobalamin (vitamin B12), methylene blue as well glucocorticoids have shown the potential to improve outcomes of patients with sepsis and septic shock; international committees launched new global definition and managing recommendations for acute respiratory distress syndrome (ARDS). Besides, a cluster of new evidences has emerged in many aspects as following: fluid control strategy in sepsis (restrictive/liberative), antibiotic infusion strategy (continuous/intermittent), oxygen-saturation targets for mechanical ventilation (conservative/liberative), blood pressure targets after resuscitation from out-of-hospital cardiac arrest (hypotension/hypertension), blood pressure targets after successful stroke thrombectomy (intensive/conventional), and nutritional support strategies (low protein-calories/conventional protein-calories, fasting/persistent feeding before extubation). Thus, given above progress, carrying out high -quality domestic multi-center clinical registration researches, constructing shareable standardized databases, as well raising public awareness of sepsis, should be the essential steps to improve our level of intensive care medicine.

ABSTRACT

Objective:To explore the relationship between the completion time of fluid resuscitation as well as negative fluid balance volumes and the prognosis of patients with septic shock, and to try to construct a prediction model based on the completion time of fluid resuscitation and negative fluid balance volumes, and to verify the predictive efficacy of the model on the prognosis of patients with septic shock.Methods:Patients with septic shock admitted to Wuxi People's Hospital from April 2020 to April 2023 were selected. The general data (gender, age, body mass index, infection site), pathological indicators on admission, the difference of acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) and sequential organ failure assessment (SOFA) between admission and 24 hours after fluid resuscitation, the completion time of fluid resuscitation and negative fluid balance volume were recorded. Multivariate Logistic analysis was used to screen the influencing factors of the prognosis of patients with septic shock, and a nomogram model was established. Bootstrap method was used for internal validation of the model. The consistency index, calibration curve and receiver operator characteristic curve (ROC curve) were used to evaluate the accuracy and prediction efficiency of the model.Results:A total of 96 patients with septic shock were enrolled, 38 patients died and 58 patients survived at 28 days. Compared with the survival group, the difference of APACHEⅡscore, SOFA score, the proportion of fluid resuscitation completed within 1 to 3 hours, and the proportion of negative fluid balance volume -500 to -250 mL per day in the death group were lower, and the differences were statistically significant (all P < 0.05). Multivariate Logistic analysis showed that the completion time of fluid resuscitation was a risk factor for the prognosis of patients with septic shock [odds ratio ( OR) = 26.285, 95% confidence interval (95% CI) was 9.984-76.902, P < 0.05]. The difference of APACHEⅡscore ( OR = 0.045, 95% CI was 0.015-0.131), SOFA score ( OR = 0.056, 95% CI was 0.019-0.165) between admission and 24 hours after fluid resuscitation, and negative fluid balance volume ( OR = 0.043, 95% CI was 0.015-0.127) were protective factors for the prognosis of patients with septic shock (all P < 0.05). The model validation results showed that the consistency index was 0.681 (95% CI was 0.596-0.924), indicating good discrimination. The calibration curve showed that the calibration curve fitted well with the ideal curve. The ROC curve showed that the sensitivity of the nomogram model for predicting the death of patients with septic shock was 83.7%, the specificity was 97.2%, and the area under the ROC curve (AUC) was 0.931 (95% CI was 0.846-0.985), indicating that the model had good prediction efficiency. Conclusion:The completion time of fluid resuscitation and negative fluid balance volumes are related to the prognosis of septic shock patients, and the alignment diagram model improve the identification of the risk of death in septic shock patients.

ABSTRACT

Objective:To observe the clinical effect of Shenfu injection in preventing septic cardiomyopathy (SIC) in septic patients.Methods:From June 2022 to January 2023, patients with sepsis or septic shock who did not develop SIC were randomly divided into treatment group and control group according to the ratio of 1:1. In the treatment group, Shenfu injection (50 mL) was pumped intravenously once every 12 hours for 5 days. In the control group, 50 mL of normal saline was pumped intravenously once every 12 hours, and the course of treatment was 5 days. The primary end point was the incidence of SIC in the first 5 days. The secondary end points were the application time of vasoactive drugs, fluid balance in the previous week, hospitalization time in ICU, total ventilation time and 28-day mortality.Results:112 patients were randomly divided into two groups. Seven patients in the treatment group were excluded twice, and finally 49 patients were included in the analysis, while six patients in the control group were excluded twice and 50 patients included in the analysis. The total incidence of SIC in the treatment group within 5 days was significantly lower than that in the control group (42.9% vs. 64.0%, P = 0.035). Among them, the left ventricular systolic dysfunction in the treatment group was significantly lower than that in the control group (24.5% vs 52.0%, P=0.005), and there was no significant difference in the incidence of left ventricular diastolic dysfunction between the two groups. The incidence of right ventricular dysfunction in the control group was 28.0%, which was significantly higher than 10.2% in the treatment group ( P = 0.025). The duration of using vasoconstrictors in the treatment group was 75(48, 97) hours, which was significantly lower than 97(66, 28) hours in the control group ( P = 0.039). The duration of inotropic drugs use in the treatment group was 32(18, 49) h, which was also significantly shorter than 44(25, 61) h in the control group ( P=0.046). The fluid balance of the control group in the first week was (1 260±850) mL, which was significantly higher than (450±520) mL in the treatment group ( P=0.008). There was no statistical difference in ICU stay, total ventilation time and 28-day mortality between the two groups (all P > 0.05). Conclusion:Early application of Shenfu injection can significantly reduce the incidence of SIC, accompanied by less use of vasoactive drugs and positive fluid balance, which has a good clinical application prospect.

ABSTRACT

OBJECTIVE To compare the clinical effects of different doses of meropenem in the treatment of septic shock. METHODS One hundred and six patients with septic shock were randomly divided into standard-dose group and high-dose group, with 53 cases in each group. Patients in the standard-dose group were given standard dose of meropenem (initial intravenous injection of 1 g meropenem more than 30 minutes, followed by 1 g meropenem intravenously every 8 hours, each time for more than 3 hours); patients in the high-dose group were given high dose of meropenem (initial intravenous injection of 2 g meropenem more than 30 minutes, followed by 2 g meropenem intravenously every 8 hours, each time for more than 3 hours); other treatment measures were determined based on the specific conditions of the patients. The main observation indicators were the increments of sequential organ failure assessment (SOFA) scores and simplified acute physiology score Ⅱ (SAPS Ⅱ) after 3, 5 and 7 days of treatment in both groups. Secondary observation indicators included in-hospital mortality, 90-day all-cause mortality, 7-day microbial cure rate, 7-day clinical cure rate, serum procalcitonin (PCT) and C-reactive protein (CRP) levels after 3, 5 and 7 days of treatment, hospitalization days in the intensive care unit, ventilator treatment days, the highest dose of norepinephrine. The occurrence of adverse drug reaction in the two groups was observed. RESULTS The increments of SOFA scores and SAPS Ⅱ after 7 days of treatment, the levels of PCT and CRP after 5 and 7 days of treatment as well as the 90-day all-cause mortality in the high- dose group were significantly lower than the standard-dose group (P<0.05). There were no statistically significant differences in other indicators between the two groups (P>0.05). CONCLUSIONS High-dose meropenem treatment for septic shock has better clinical effects and is safer than standard-dose meropenem.

ABSTRACT

@#Vibrio vulnificus is a halophilic gram-negative bacillus that can cause fulminant septicaemia in immunocompromised patients. A 67-year-old man who was immunosuppressed as a result of cytotoxic chemotherapy presented with a brief history of fever, lethargy, myalgia, and reduced oral intake. He had recently travelled to the beach to consume seafood. His blood pressure was 81/47 mm Hg, necessitating fluid resuscitation followed by inotropic support and admission to the intensive care unit. His blood culture was positive for curved gram-negative bacilli. The isolate was oxidase-positive and produced an acid butt with an alkaline slant in triple sugar iron agar. Matrix-assisted laser desorption ionization-time of flight mass spectrometry conclusively identified the isolate as V. vulnificus. Intravenous ceftazidime plus ciprofloxacin were administered, and by the fifth day of admission, he was successfully transferred out to the general ward. In total, the patient completed a 14-day course of antibiotic therapy.

ABSTRACT

Objective:To explore the clinical characteristics of children with septic shock and analyze the drug resistance of blood culture positive bacteria.Methods:The clinical data,positive blood culture strains and drug sensitivity results of 127 children with septic shock admitted to the Department of Intensive Care Medicine of Hunan Children's Hospital from September 2015 to August 2021 were retrospectively analyzed.Results:A total of 134 strains of bacteria or fungi were isolated from the blood culture samples of 127 children with septic shock,and gram-negative strains were the main ones,accounting for 67.16% (90/134).Haemophilus influenzae and Escherichia coli were the main gram-negative bacteria,accounting for 38.81% (52/134) and 20.15% (27/134),respectively,while Streptococcus pneumoniae was the main gram-positive bacteria,accounting for 8.21% (11/134),and Candida albicans was the main fungus,accounting for 10.45% (14/134).The number of white blood cells,the levels of serum C-reactive protein,procalcitonin,venous blood sugar and arterial blood lactic acid in patients were all significantly higher than normal values,and the white blood cells count and neutrophil percentage in gram-positive bacterial infections were significantly higher than those with gram-negative bacterial infections and fungal infections( P<0.05).Procalcitonin increased most obviously when infected by gram-negative bacteria,and the difference was statistically significant ( P<0.05).Gram-positive strains were sensitive to vancomycin,teicoplanin,and linezolid,but only 50% of Streptococcus pneumoniae were sensitive to penicillin.Gram-negative strains had relatively high drug resistance,among which Klebsiella pneumoniae were only highly resistant to imipenem,cilastatin and levofloxacin,reaching 50%.Haemophilus influenzae was resistant to cephalosporins and β-amides enzyme antibiotic,and the drug sensitivity rate of lactamase antibiotics was high,with a resistance rate of 50% only to ampicillin,cefuroxime,amikacin,and compound sulfamethoxazole.There were not many fungal strains,and most antifungal drugs were effective against blood culture-positive fungi. Conclusion:The main pathogens of infection in children with septic shock are gram-negative bacteria,and have high resistance to general antibiotics.We should pay attention to their drug resistance when using antibiotics empirically.

ABSTRACT

Objective:To study the early predictors of refractory septic shock (RSS) in neonates.Methods:From July 2020 to December 2021, clinical data of neonates with septic shock admitted to the Neonatal Department of our hospital were retrospectively reviewed. According to the maximum septic shock score (SSS) during clinical course, the neonates were assigned into RSS group and non-RSS group. Perinatal data, laboratory results and hemodynamic parameters at diagnosis were compared between the two groups. Multiple logistic regression analysis was used to identify independent risk factors of RSS and septic shock-related death. Receiver operating characteristic (ROC) curve was constructed to evaluate the early predictors of poor prognosis.Results:A total of 130 neonates were enrolled, including 54 in RSS group and 76 in non-RSS group. Compared with the non-RSS group, the RSS group had significantly lower pH, base excess (BE), stroke volume index (SVI), cardiac output (CO) and cardiac index (CI).Meanwhile, the RSS group had significantly higher mean arterial pressure (MAP) to CI ratio (MAP/CI) and SSS [including bedside SSS (bSSS), computed SSS (cSSS) and modified version of cSSS (mcSSS)] (all P<0.05). Multiple logistic regression analysis showed that increased MAP/CI was an independent predictor of RSS. The cut-off value of MAP/CI was 11.6 [sensitivity 62%, specificity 87%, positive predictive value (PPV) 79% and negative predictive value (NPV) 77%], with an area under the curve (AUC) of 0.734. Increased mcSSS was an independent predictor of septic shock-related death. The cut-off value of mcSSS was 5.8 (sensitivity 83%, specificity 72%, PPV 21% and NPV 97%), with an AUC of 0.845. Conclusions:Increased MAP/CI (≥11.6) and mcSSS (≥5.8) may be early predictors of RSS and septic shock-related death in neonates.

ABSTRACT

Abstract Background: The optimal amount for initial fluid resuscitation is still controversial in sepsis and the contribution of non-resuscitation fluids in fluid balance is unclear. We aimed to investigate the main components of fluid intake and fluid balance in both survivors and non-survivor patients with septic shock within the first 72 hours. Methods: In this prospective observational study in two intensive care units, we recorded all fluids administered intravenously, orally, or enterally, and losses during specific time intervals from vasopressor initiation: T1 (up to 24 hours), T2 (24 to 48 hours) and T3 (48 to 72 hours). Logistic regression and a mathematical model assessed the association with mortality and the influence of severity of illness. Results: We included 139 patients. The main components of fluid intake varied across different time intervals, with resuscitation and non-resuscitation fluids such as antimicrobials and maintenance fluids being significant contributors in T1 and nutritional therapy in T2/T3. A positive fluid balance both in T1 and T2 was associated with mortality (p = 0.049; p = 0.003), while nutritional support in T2 was associated with lower mortality (p = 0.040). The association with mortality was not explained by severity of illness scores. Conclusions: Non-resuscitation fluids are major contributors to a positive fluid balance within the first 48 hours of resuscitation. A positive fluid balance in the first 24 and 48 hours seems to independently increase the risk of death, while higher amount of nutrition seems protective. This data might inform fluid stewardship strategies aiming to improve outcomes and minimize complications in sepsis.
