RESUMO
INTRODUCTION: Acute pancreatitis poses a significant health risk due to the potential for pancreatic necrosis and multi-organ failure. Fluid resuscitation has demonstrated positive effects; however, consensus on the ideal intravenous fluid type and infusion rate for optimal patient outcomes remains elusive. METHODS: A comprehensive literature search was conducted using PubMed, Embase, the Cochrane Library, Scopus, and Google Scholar for studies published between 2005 and January 2023. Reference lists of potential studies were manually searched to identify additional relevant articles. Randomized controlled trials and retrospective studies comparing high (≥ 20 ml/kg/h), moderate (≥ 10 to < 20 ml/kg/h), and low (5 to < 10 ml/kg/h) fluid therapy in acute pancreatitis were considered. RESULTS: Twelve studies met our inclusion criteria. Results indicated improved clinical outcomes with low versus moderate fluid therapy (OR = 0.73; 95% CI [0.13, 4.03]; p = 0.71) but higher mortality rates with low compared to moderate (OR = 0.80; 95% CI [0.37, 1.70]; p = 0.55), moderate compared to high (OR = 0.58; 95% CI [0.41, 0.81], p = 0.001), and low compared to high fluids (OR = 0.42; 95% CI [0.16, 1.10]; P = 0.08). Systematic complications improved with moderate versus low fluid therapy (OR = 1.22; 95% CI [0.84, 1.78]; p = 0.29), but no difference was found between moderate and high fluid therapy (OR = 0.59; 95% CI [0.41, 0.86]; p = 0.006). DISCUSSION: This meta-analysis revealed differences in the clinical outcomes of patients with AP receiving low, moderate, and high fluid resuscitation. Low fluid infusion demonstrated better clinical outcomes but higher mortality, systemic complications, and SIRS persistence than moderate or high fluid therapy. Early fluid administration yielded better results than rapid fluid resuscitation.

BACKGROUND: Current recommendations support guiding fluid resuscitation through the assessment of fluid responsiveness. Recently, the concept of fluid tolerance and the prevention of venous congestion (VC) have emerged as relevant aspects to be considered to avoid potentially deleterious side effects of fluid resuscitation. However, there is paucity of data on the relationship of fluid responsiveness and VC. This study aims to compare the prevalence of venous congestion in fluid responsive and fluid unresponsive critically ill patients after intensive care (ICU) admission. METHODS: Multicenter, prospective cross-sectional observational study conducted in three medical-surgical ICUs in Chile. Consecutive mechanically ventilated patients that required vasopressors and admitted < 24 h to ICU were included between November 2022 and June 2023. Patients were assessed simultaneously for fluid responsiveness and VC at a single timepoint. Fluid responsiveness status, VC signals such as central venous pressure, estimation of left ventricular filling pressures, lung, and abdominal ultrasound congestion indexes and relevant clinical data were collected. RESULTS: Ninety patients were included. Median age was 63 [45-71] years old, and median SOFA score was 9 [7-11]. Thirty-eight percent of the patients were fluid responsive (FR+), while 62% were fluid unresponsive (FR-). The most prevalent diagnosis was sepsis (41%) followed by respiratory failure (22%). The prevalence of at least one VC signal was not significantly different between FR+ and FR- groups (53% vs. 57%, p = 0.69), as well as the proportion of patients with 2 or 3 VC signals (15% vs. 21%, p = 0.4). We found no association between fluid balance, CRT status, or diagnostic group and the presence of VC signals. CONCLUSIONS: Venous congestion signals were prevalent in both fluid responsive and unresponsive critically ill patients. The presence of venous congestion was not associated with fluid balance or diagnostic group. Further studies should assess the clinical relevance of these results and their potential impact on resuscitation and monitoring practices.

BACKGROUND AND AIM: We aimed to evaluate comparative outcomes of aggressive versus non-aggressive intravenous fluid (IVF) therapy in patients with acute pancreatitis. METHODS: A systematic search of electronic data sources and bibliographic reference lists were conducted. All randomized controlled trials (RCTs) reporting outcomes of aggressive versus non-aggressive IVF therapy in acute pancreatitis were included and their risk of bias were assessed. Effect sizes were determined for overall mortality, systemic inflammatory response syndrome (SIRS), sepsis, respiratory failure, pancreatic necrosis, severe pancreatitis, clinical improvement, AKI, and length of stay using random-effects modeling. Trial sequential analysis was conducted to determine risk of types 1 or 2 errors. RESULTS: We included 10 RCTs reporting 993 patients with acute pancreatitis who received aggressive (n = 475) or non-aggressive (n = 518) IVF therapy. Aggressive IVF therapy was associated with significantly higher rate of sepsis (OR: 2.68, P = 0.0005) and longer length of stay (MD: 0.94, P < 0.00001) compared with the non-aggressive approach. There was no statistically significant difference in mortality (RD: 0.02, P = 0.31), SIRS (OR: 0.93, P = 0.89), respiratory failure (OR: 2.81, P = 0.07), pancreatic necrosis (OR: 1.98, P = 0.06), severe pancreatitis (OR: 1.31, P = 0.38), clinical improvement (OR: 1.12, P = 0.83) or AKI (OR: 1.06, P = 0.91) between the two groups. Sub-group analysis demonstrated higher morbidity and mortality associated with the aggressive approach in more severe disease. Trial sequential analysis detected risk of type 2 error. CONCLUSIONS: Aggressive IVF therapy may be associated with higher morbidity in patients with acute pancreatitis compared with the non-aggressive approach, particularly in patients with more severe disease. It may also prolong length of hospital stay. The available evidence is subject to type 2 error indicating the need for adequately powered RCTs.
RESUMO
BACKGROUND: Acute kidney injury (AKI) is common in sepsis and a urine output <0.5â mL/kg/h associated with increased mortality is incorporated into AKI diagnosis. We aimed to identify the urine-output threshold associated with increased AKI incidence and hypothesized that a higher urine output than a specified threshold, which differs from the predominantly used 0.5â mL/kg/h threshold, would be associated with an increased AKI incidence. METHODS: This was a post-hoc analysis of a nationwide prospective observational study. This study included adult patients newly diagnosed with sepsis and requiring intensive care. Urine output on the day of sepsis diagnosis was categorized as low, moderate, or high (<0.5, 0.5-1.0, and >1.0â mL/kg/h, respectively), and we compared AKI incidence, renal replacement therapy (RRT) requirement, and 28-day survival by category. Estimated probabilities for these outcomes were also compared after adjusting for patient background and hourly fluid administration. RESULTS: Among 172 eligible patients, AKI occurred in 46.3%, 48.3%, and 53.1% of those with high, moderate, and low urine output, respectively. The probability of AKI was lower in patients with high urine output than in those with low output (43.6% vs 56.5%; P = .028), whereas RRT requirement was lower in patients with high and moderate urine output (11.7% and 12.8% vs 49.1%; P < .001). Patients with low urine output demonstrated significantly lower survival (87.7% vs 82.8% and 67.8%; P = .018). Cubic spline curves for AKI, RRT, and survival prediction indicated different urine-output thresholds, including <1.2 to 1.3â mL/kg/h for AKI and <0.6 to 0.8â mL/kg/h for RRT and mortality risk. CONCLUSIONS: Urine output >1.0â mL/kg/h on the day of sepsis diagnosis was associated with lower AKI incidence. The urine-output threshold was higher for developing AKI than for RRT requirement or mortality.
RESUMO
Background: This study aims to investigate the safety and efficacy of guideline-directed fluid resuscitation (GDFR) compared with conservative fluid management in end-stage renal disease (ESRD) patients with sepsis by evaluating 90-day mortality and intubation rate. Methods: Following PRISMA guidelines, a systematic review was conducted across multiple databases using specific keywords and controlled vocabulary. The search strategy, implemented until October 1, 2023, aimed to identify studies examining fluid resuscitation in ESRD patients with sepsis. The review process was streamlined using Covidence software. A fourth reviewer resolved discrepancies in study inclusion. A random-effects model with the generic Mantel-Haenszel method was preferred for integrating odds ratios (ORs). Sensitivity analysis and publication bias analysis were performed. Results: Of the 1274 identified studies, 10 were selected for inclusion, examining 1184 patients, 593 of whom received GDFR. Four studies were selected to investigate the intubation rate, including 304 patients. No significant mortality or intubation rate difference was spotted between both groups [OR = 1.23; confidence interval (CI) = 0.92-1.65; I2 = 0% and OR = 1.91; CI = 0.91-4.04]. In most studies, sensitivity analysis using the leave-one-out approach revealed higher mortality and intubation rates. The Egger test results indicated no statistically significant publication bias across the included studies. Conclusion: Our research contradicts the common assumption about the effectiveness of GDFR for sepsis patients with ESRD. It suggests that this approach, while not superior to the conservative strategy, may potentially be harmful.
RESUMO
Adequate fluid therapy is crucial for resuscitation after major burns. To adapt this to individual patient demands, standard is adjustment of volume to laboratory parameters and values of enhanced hemodynamic monitoring. To implement calibrated parameters, patients must have reached the intensive care unit (ICU). The aim of this study was, to evaluate the use of an auto-calibrated enhanced hemodynamic monitoring device to improve fluid management before admission to ICU. We used PulsioflexProAqt® (Getinge) during initial treatment and burn shock resuscitation. Analysis was performed regarding time of measurement, volume management, organ dysfunction, and mortality. We conducted a monocentre, prospective cohort study of 20 severely burned patients, >20% total body surface area (TBSA), receiving monitoring immediately after admission. We compared to 57 patients, matched in terms of TBSA, age, sex, and existence of inhalation injury out of a retrospective control group, who received standard care. Hemodynamic measurement with autocalibrated monitoring started significantly earlier: 3.75(2.67-6.0) hours (h) after trauma in the study group versus 13.6(8.1-17.5) h in the control group (P < .001). Study group received less fluid after 6 h: 1.7(1.2-2.2) versus 2.3(1.6-2.8) ml/TBSA%/kg, P = .043 and 12 h: 3.0(2.5-4.0) versus 4.2(3.1-5.0) ml/TBSA%/kg, P = .047. Dosage of norepinephrine was higher after 18â h in the study group: 0.20(0.12-0.3) versus 0.08(0.02-0.18) µg/kg/min, P = .014. The study group showed no adult respiratory distress syndrome versus 21% in the control group, P = .031. There was no difference in other organ failures, organ replacement therapy, and mortality. The use of auto-calibrated enhanced hemodynamic monitoring is a fast and feasible way to guide early fluid therapy after burn trauma. It reduces the time to reach information about patient's volume capacity. Management of fluid application changed to a more restrictive fluid use in the early period of burn shock and led to a reduction of pulmonary complications.

BACKGROUND: Acute kidney injury (AKI) is a recognized comorbidity in pediatric diabetic ketoacidosis (DKA), although the exact etiology is unclear. The unique physiology of DKA makes dehydration assessments challenging, and these patients potentially receive excessive amounts of intravenous fluids (IVF). We hypothesized that dehydration is over-estimated in pediatric DKA, leading to over-administration of IVF and hyperchloremia that worsens AKI. METHODS: Retrospective cohort of all DKA inpatients at a tertiary pediatric hospital from 2014 to 2019. A total of 145 children were included; reasons for exclusion were pre-existing kidney disease or incomplete medical records. AKI was determined by change in creatinine during admission, and comparison to a calculated baseline value. Linear regression multivariable analysis was used to identify factors associated with AKI. True dehydration was calculated from patients' change in weight, as previously validated. Fluid over-resuscitation was defined as total fluids given above the true dehydration. RESULTS: A total of 19% of patients met KDIGO serum creatinine criteria for AKI on admission. Only 2% had AKI on hospital discharge. True dehydration and high serum urea levels were associated with high serum creatinine levels on admission (p = 0.042; p < 0.001, respectively). Fluid over-resuscitation and hyperchloremia were associated with delayed kidney recovery (p < 0.001). Severity of initial AKI was associated with cerebral edema (p = 0.018). CONCLUSIONS: Dehydration was associated with initial AKI in children with DKA. Persistent AKI and delay to recovery was associated with hyperchloremia and over-resuscitation with IVF, potentially modifiable clinical variables for earlier AKI recovery and reduction in long-term morbidity. This highlights the need to re-address fluid protocols in pediatric DKA.

BACKGROUND: Fluid resuscitation is one of the main therapies for acute pancreatitis (AP). There is still no consensus on the type of fluid resuscitation. This study investigated the differences between lactate Ringer's (LR) and normal saline (NS) in treating AP. METHODS: Two authors systematically searched Web of Science, Embase (via OVID), Cochrane Library, and PubMed to find all published research before July, 2023. The odds of moderately severe/severe AP and intensive care unit (ICU) admission are set as primary endpoints. RESULTS: This meta-analysis included 5 RCTs and 4 observational studies with 1424 AP patients in LR (n = 651) and NS (n = 773) groups. The results suggested that the odds of moderately severe/severe AP (OR 0.48; 95%Cl 0.34 to 0.67; P < 0.001) and ICU admission (OR 0.37; 95%Cl 0.16 to 0.87; P = 0.02) were lower in the LR group compared to NS group. In addition, the LR group had lower rates of local complications (OR 0.54; 95%Cl 0.32 to 0.92; P = 0.02), lower level of CRP, as well as a shorter hospital stay (WMD, - 1.09 days; 95%Cl - 1.72 to - 0.47 days; P < 0.001) than the NS group. Other outcomes, such as mortality, the rate of organ failure, SIRS, acute fluid collection, pancreatic necrosis, pseudocysts, and volume overload, did not differ significantly between two groups (P > 0.05). CONCLUSIONS: LR is preferred over NS as it decreases the odds of moderately severe/severe AP, the rate of ICU admission, local complication, and length of hospital stay. However, large-scale RCT are lacking to support these evidence.

This randomized controlled trial aimed to determine whether lung ultrasound-guided fluid resuscitation improves the clinical outcomes of neonates with septic shock. Seventy-two patients were randomly assigned to undergo treatment with lung ultrasound-guided fluid resuscitation (LUGFR), or with usual fluid resuscitation (Control) in the first 6 h since the start of the sepsis treatment. The primary study outcome was 14-day mortality after randomization. Fourteen-day mortalities in the two groups were not significantly different (LUGFR group, 13.89%; control group, 16.67%; p = 0.76; hazard ratio 0.81 [95% CI 0.27-2.50]). The LUGFR group experienced shorter length of neonatal intensive care unit (NICU) stays (21 vs. 26 days, p = 0.04) and hospital stays (32 vs. 39 days, p = 0.01), and less fluid was used in the first 6 h (77 vs. 106 mL/kg, p = 0.02). Further, our study found that ultrasound-guided fluid resuscitation can significantly reduce the incidence of acute kidney injury (25% vs. 47.2%, p = 0.05) and intracranial hemorrhage (grades I-II) within 72 h (13.9% vs. 36.1%, p = 0.03). However, no significant difference was found in the resolution of shock within 1 h or 6 h, use of mechanical ventilation or vasopressor support, time to achieve lactate level < 2 mmol/L, and the number of participants developing hepatomegaly in the first 6 h. CONCLUSION: Lung ultrasound is a noninvasive and convenient tool for predicting fluid overload in neonatal septic shock. Fluid resuscitation guided by lung ultrasound can shorten the length of hospital and NICU stays, reduce the amount of fluid used in the first 6 h, and reduce the risk of acute kidney injury and intracranial hemorrhage. TRIAL REGISTRATION: Registered in Guangdong Second Provincial General Hospital: 2021-IIT-156-EK, date of registration: November 13, 2021. And ClinicalTrials.gov: NCT06144463 (retrospectively registered). WHAT IS KNOWN: ⢠Excessive fluid resuscitation in neonates with septic shock had worse outcomes. WHAT IS NEW: ⢠Lung ultrasound should be routinely used to guide fluid resuscitation in neonatal septic shock.

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.

The number of critically ill patients that present to emergency departments across the world has risen steadily for nearly two decades. Despite a decrease in initial emergency department (ED) volumes early in the COVID-19 pandemic, the proportion of critically ill patients is now higher than pre-pandemic levels [1]. The emergency physician (EP) is often the first physician to evaluate and resuscitate a critically ill patient. In addition, EPs are frequently tasked with providing critical care long beyond the initial resuscitation. Prolonged boarding of critically ill patients in the ED is associated with increased duration of mechanical ventilation, increased intensive care unit (ICU) length of stay, increased hospital length of stay, increased medication-related adverse events, and increased in-hospital, 30-day, and 90-day mortality [2-4]. Given the continued increase in critically ill patients along with the increases in boarding critically ill patients in the ED, it is imperative for the EP to be knowledgeable about recent literature in resuscitation and critical care medicine, so that critically ill patients continue to receive evidence-based care. This review summarizes important articles published in 2022 that pertain to the resuscitation and management of select critically ill ED patients. These articles have been selected based on the authors review of key critical care, resuscitation, emergency medicine, and medicine journals and their opinion of the importance of study findings as it pertains to the care of the critically ill ED patient. Topics covered in this article include cardiac arrest, post-cardiac arrest care, rapid sequence intubation, mechanical ventilation, fluid resuscitation, and sepsis.

PURPOSE: The integrity of the endothelial glycocalyx (EG), a critical player in vascular homeostasis, reportedly influences the outcomes of critically ill patients. We investigated the effect of 5% albumin, which preserved EG integrity in preclinical studies, vs balanced crystalloid solution on EG degradation in patients undergoing off-pump coronary surgery. METHODS: Patients were randomized to receive either 5% albumin (N = 51) or balanced crystalloid solution (Plasma-Lyte [Baxter Incorporated, Seoul, Republic of Korea]; N = 53) for intravenous volume replacement during surgery (double-blinded). The primary outcome was plasma syndecan-1 concentration, a marker of EG degradation, measured after anesthetic induction (baseline), completion of grafting, and sternal closure. Secondary outcomes were atrial natriuretic peptide (ANP), tumour necrosis factor (TNF)-α, soluble thrombomodulin, and perioperative fluid balance. RESULTS: The mean (standard deviation) fluid requirements were 833 (270) mL and 1,323 (492) mL in the albumin and Plasma-Lyte group, respectively (mean difference, -489 mL; 95% confidence interval [CI], -643 to -335; P < 0.001). Plasma syndecan-1 concentration increased after completion of grafting (median difference, 116 ng·mL-1; 95% CI, 67 to 184; P < 0.001) and sternal closure (median difference, 57 ng·mL-1; 95% CI, 36 to 80; P < 0.001) compared with those at baseline, without any intergroup differences. Atrial natriuretic peptide, TNF-α, and soluble thrombomodulin concentrations were similar between the two groups. The amount of chest tube drainage was greater in the albumin group than that in the Plasma-Lyte group (median difference, 190 mL; 95% CI, 18 to 276; P = 0.03). CONCLUSION: Off-pump coronary surgery was associated with significant EG degradation. Yet, intraoperative fluid therapy with 5% albumin could not ameliorate EG degradation when compared with balanced crystalloid solution. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03699462); first posted 9 October 2018.
RéSUMé: OBJECTIF: L'intégrité du glycocalyx endothélial (GE), un acteur essentiel de l'homéostasie vasculaire, influencerait le devenir des patient·es gravement malades. Nous avons étudié l'effet de l'albumine à 5 %, qui préservait l'intégrité du GE dans les études précliniques, par rapport à une solution cristalloïde équilibrée sur la dégradation du GE chez les patient·es bénéficiant d'une chirurgie coronarienne à cÅur battant. MéTHODE: Les patient·es ont été randomisé·es à recevoir soit de l'albumine à 5 % (N = 51) ou de la solution cristalloïde équilibrée (Plasma-Lyte [Baxter Incorporated, Séoul, République de Corée]; N = 53) pour le remplacement du volume intraveineux pendant la chirurgie (en double aveugle). Le critère d'évaluation principal était la concentration plasmatique de syndécan-1, un marqueur de la dégradation du GE, mesurée après l'induction de l'anesthésie (ligne de base), la fin de la greffe et la fermeture du sternum. Les critères d'évaluation secondaires étaient le peptide natriurétique auriculaire (ANP), le facteur de nécrose tumorale (TNF)-α, la thrombomoduline soluble et le bilan hydrique périopératoire. RéSULTATS: Les besoins liquidiens moyens (écart type) étaient de 833 (270) mL et 1323 (492) mL dans les groupes albumine et Plasma-Lyte, respectivement (différence moyenne, −489 mL; intervalle de confiance [IC] à 95 %, −643 à −335; P < 0,001). La concentration plasmatique de syndécan-1 a augmenté après la fin de la greffe (différence médiane, 116 ng·mL−1; IC 95 %, 67 à 184; P < 0,001) et la fermeture du sternum (différence médiane, 57 ng·mL−1; IC 95 %, 36 à 80; P < 0,001) par rapport aux concentrations au départ, sans différences intergroupe. Les concentrations de peptide natriurétique auriculaire, de TNF-α et de thrombomoduline soluble étaient similaires entre les deux groupes. La quantité de drainage du drain thoracique était plus importante dans le groupe albumine que dans le groupe Plasma-Lyte (différence médiane, 190 mL; IC 95 %, 18 à 276; P = 0,03). CONCLUSION: La chirurgie coronarienne à cÅur battant a été associée à une dégradation significative du glycocalyx endothélial. Pourtant, la fluidothérapie peropératoire avec 5 % d'albumine n'a pas pu améliorer la dégradation du GE par rapport à une solution cristalloïde équilibrée.

OBJECTIVES: To estimate the use of albumin among adults undergoing thoracic surgery in the United States, compare baseline characteristics, clinical and cost outcomes of recipients versus nonrecipients, and determine albumin's contribution to total hospital costs. DESIGN: Retrospective cohort study. SETTING: Nationwide sample of US hospitals. PARTICIPANTS: Adults undergoing open and minimally invasive thoracic surgery between 2011 and 2017. INTERVENTIONS: Albumin on the day of surgery (identified using itemized hospital billing logs). MEASUREMENTS AND MAIN RESULTS: Albumin was used in 170 of 342 US hospitals, among 13% and 7% of 14,672 and 22,532 patients who, respectively, underwent open and minimally invasive thoracic surgery (median volume 500 mL). Baseline comorbidities and organ-supportive treatments were several-fold more prevalent among recipients (particularly vasopressors, mechanical ventilation, and red cell transfusions). In standardized mortality ratio propensity score weighted analysis, albumin use was not associated with in-hospital mortality (adjusted relative risk 1.17 [0.72, 1.92] and 1.51 [0.97, 2.34], with open and minimally invasive procedures), but was associated with morbidity and higher costs, more so with minimally invasive procedures than with open surgery. Total costs among recipients were higher by $4,744 ($3,591, $5,897) and $5,088 ($4,075, $6,100) for open and minimally invasive procedures, respectively. Albumin accounted for 2.6% of this difference (median $124 [$83-$189] per patient). CONCLUSIONS: Albumin use varies widely across hospitals, and 9% of patients receive it (median 500 mL). Use was not associated with in-hospital mortality and was associated with more morbidity and cost. The cost of albumin accounted for a trivial portion of hospital costs. Clinical trials must examine the effects of albumin on complications and costs after thoracic surgery.
RESUMO
INTRODUCTION: Fluid resuscitation reduces mortality and morbidity in acute pancreatitis (AP); however, whether glucose-containing fluids negatively impact AP remains uncertain. We aimed to examine the association between glucose-containing fluids and AP outcomes. METHODS: This multicenter retrospective cohort study included patients diagnosed with AP between January 2015 and December 2018. Glucose density was defined as total glucose content divided by total fluid volume (g/dl) on day 1, and was considered high if the level exceeded the median. Endpoints were early organ failure (OF), including cardiovascular, renal, or respiratory system failure within 7 days; 30-day OF; ICU admission; and AP-related 90-day mortality. Logistic regression models, restricted cubic spline curves, and Cox proportional hazards models were used for statistical analysis. RESULTS: From the database, 1,146 patients with AP were included. Early OF occurred in 8.8% of patients within 7 days. The high glucose-density group (>5 g/dl) had increased risk of early OF (9.7% vs. 8.2%; adjusted odds ratio [aOR], 1.69; 95% confidence interval [CI], 1.03-2.80; P = 0.039), respiratory failure (8.0% vs. 6.2%; aOR, 1.88; 95% CI, 1.09-3.24; P = 0.024), cardiovascular failure (3.4% vs. 2.4%; aOR, 3.59; 95% CI, 1.28-10.0; P = 0.015), and ICU admission (6.8% vs. 5.8%; aOR, 2.06; 95% CI, 1.08-3.94; P = 0.029), with a dose-response effect observed for cardiovascular failure and ICU admission. A significant increase 30-day OF risk (adjusted hazard ratio [aHR], 1.70; 95% CI, 1.19-2.45) was also noted. CONCLUSION: Excess glucose-containing fluid was associated with increased risks of overall, respiratory, and cardiovascular OF and ICU admission in AP.
RESUMO
BACKGROUND: Sepsis fluid resuscitation is controversial, especially for patients with volume overload risk. The Surviving Sepsis Campaign recommends a 30-mL/kg crystalloid fluid bolus for patients with sepsis-induced hypoperfusion. Criticism of this approach includes excessive fluid resuscitation in certain patients. OBJECTIVE: The aim of this study was to assess the efficacy and safety of guideline-concordant fluid resuscitation in patients with sepsis and heart failure (HF) or end-stage kidney disease (ESKD). METHODS: A retrospective cohort study was conducted in patients with sepsis who qualified for guideline-directed fluid resuscitation and concomitant HF or ESKD. Those receiving crystalloid fluid boluses of at least 30 mL/kg within 3 h of sepsis diagnosis were placed in the concordant group and all others in the nonconcordant group. The primary outcome was in-hospital mortality. Secondary outcomes included intensive care unit (ICU) and hospital length of stay (LOS); vasoactive medications and net volume over 24 h; new mechanical ventilation, new or increased volume removal, and acute kidney injury within 48 h; and shock-free survival at 7 days. RESULTS: One hundred twenty-five patients were included in each group. In-hospital mortality was 34.4% in the concordant group and 44.8% in the nonconcordant group (p = 0.1205). The concordant group had a shorter ICU LOS (7.6 vs. 10.5 days; p = 0.0214) and hospital LOS (12.9 vs. 18.3 days; p = 0.0163), but increased new mechanical ventilation (37.6 vs. 20.8%; p = 0.0052). No differences in other outcomes were observed. CONCLUSIONS: Receipt of a 30-mL/kg fluid bolus did not affect outcomes in a cohort of patients with mixed types of HF and sepsis-induced hypoperfusion.

Fluid resuscitation is typically needed in patients with cirrhosis, sepsis and hypotension. However, the complex circulatory changes associated with cirrhosis and the hyperdynamic state, characterised by increased splanchnic blood volume and relative central hypovolemia, complicate fluid administration and monitoring of fluid status. Patients with advanced cirrhosis require larger volumes of fluids to expand central blood volume and improve sepsis-induced organ hypoperfusion than patients without cirrhosis, which comes at the cost of a further increase in non-central blood volume. Monitoring tools and volume targets still need to be defined but echocardiography is promising for bedside assessment of fluid status and responsiveness. Large volumes of saline should be avoided in patients with cirrhosis. Experimental data suggest that independent of volume expansion, albumin is superior to crystalloids at controlling systemic inflammation and preventing acute kidney injury. However, while it is generally accepted that albumin plus antibiotics is superior to antibiotics alone in spontaneous bacterial peritonitis, evidence is lacking in patients with infections other than spontaneous bacterial peritonitis. Patients with advanced cirrhosis, sepsis and hypotension are less likely to be fluid responsive than those without cirrhosis and early initiation of vasopressors is recommended. While norepinephrine is the first-line option, the role of terlipressin needs to be clarified in this context.

Eighty percent of brain-dead (BD) organ donors develop hypotension and are frequently hypovolemic. Fluid resuscitation in a BD donor is controversial. We have previously published our 4-h goal-directed stroke volume (SV)-based fluid resuscitation protocol which significantly decreased time on vasopressors and increased transplanting four or more organs. The SV was measured by pulse-contour analysis (PCA) or an esophageal doppler monitor, both of which are invasive. Thoracic bioreactance (BR) is a non-invasive portable technology that measures SV but has not been studied in BD donors. We performed a randomized prospective comparative study of BR versus PCA technology in our fluid resuscitation protocol in BD donors. Eighty-four donors (53.1%) were randomized to BR and 74 donors to PCA (46.8%). The two groups were well matched based on 24 demographic, social, and initial laboratory factors, without any significant differences between them. There was no difference in the intravenous fluid infused over the 4-h study period [BR 2271 ± 823 vs. PCA 2230 ± 962 mL; p = .77]. There was no difference in the time to wean off vasopressors [BR 108.8 ± 61.8 vs. PCA 150.0 ± 68 min p = .07], nor in the number of donors off vasopressors at the end of the protocol [BR 16 (28.6%) vs. PCA 15 (29.4%); p = .92]. There was no difference in the total number of organs transplanted per donor [BR 3.25 ± 1.77 vs. PCA 3.22 ± 1.75; p = .90], nor in any individual organ transplanted. BR was equivalent to PCA in clinical outcomes and provides a simple, non-invasive, portable technology to monitor fluid resuscitation in organ donors.

At least 30 mL/kg of crystalloid fluid administration within the first 3 hours of resuscitation is suggested by the current Surviving Sepsis Campaign guidelines for management of sepsis and septic shock. This commentary discusses the challenges with using a weight-based approach to bolus fluid dosing during the early phase of resuscitation of adult, obese patients. Based on the available literature, arguments can be made for the use of either ideal or adjusted body weight for weight-based fluid dosing, but there are concerns with fluid overload if using actual body weight to dose patients with more severe forms of obesity.

OBJECTIVE: To compare the efficacy and safety of enteral fluid resuscitation (via nasointestinal tube or colorectal tube) and intravenous fluid resuscitation (via intravenous route) in the early treatment of severe acute pancreatitis. METHODS: In this study, 8 electronic databases (PubMed, Web of Science, Embase, Cochrane Library, Scopus, China HowNet database, Wanfang database, and VIP database) were searched to collect clinical studies from inception to June 12, 2022. After the quality evaluation and data extraction of the included studies, the RevMan 5.3 software was used for analysis. RESULTS: A total of seven studies including 580 patients were studied in this meta-analysis, in which 291 cases were treated with enteral fluid resuscitation and 289 cases were treated with intravenous fluid resuscitation. Compared with the intravenous route group, the enteral route resuscitation group reduced the incidence of new organ failure (OR = 0.23, 95% CI: 0.12-0.43, P < 0.00001), the incidence of persistent organ failure (OR = 0.38, 95% CI: 0.22-0.64, P = 0.0003), the incidence of mechanical ventilation (OR = 0.15, 95% CI: 0.03-0.69, P = 0.01), the incidence of ICU care (OR = 0.49, 95% CI: 0.27-0.88, P = 0.02), and the incidence of pancreatic infection (OR = 0.38, 95% CI: 0.17-0.83, P = 0.02). There were no statistically significant differences in mortality (OR = 0.77, 95% CI: 0.35-1.66, P = 0.50), surgical intervention rate (OR = 0.47, 95% CI: 0.19-1.18, P = 0.11), and incidence of localized ascites (OR = 0.65, 95% CI: 0.25-1.73, P = 0.39). CONCLUSION: Early enteral fluid resuscitation is safe and effective for in severe pancreatitis. But this conclusion needs to be verified by more additional multi-centre randomized controlled trials with large samples.

Perioperative anaphylaxis is associated with significant morbidity and mortality. Prompt and appropriate treatment is required for optimal outcome. Despite general knowledge of this condition, delays occur in the administration of epinephrine and in particular the use of i.v. route of administration in the perioperative setting. Barriers should be addressed to allow prompt utilisation of i.v. epinephrine in perioperative anaphylaxis.
