AI Article Synopsis
- The study investigates how different fluid resuscitation methods affect blood circulation and lung water levels in dogs experiencing septic shock.
- Four groups of dogs were treated with various solutions, including hypertonic solutions and normal saline, after being induced with septic shock.
- Results showed that hypertonic solutions lead to better hemodynamic outcomes without increasing extravascular lung water compared to normal saline, which caused an increase in lung water.
Article Abstract
Objective: To observe the effect of small volume resuscitation by hypertonic-hyperoncotic solution on the hemodynamics and extravascular lung water of septic shock dogs.
Methods: Lipopolysaccharide of E. coli was injected to 24 healthy dogs via femoral vein to induce septic shock. These septic shock dogs were resuscitated with hypertonic salt solutions (HS, 6 ml/kg, n = 6), 6% hydroxyethyl starch in combination with HS (HSS, 6 ml/kg, n=6), normal saline (NS, 100 ml/kg, n=6), and 6% hydroxyethyl starch solutions (HES, 33 ml/kg, n=6), respectively. The changes of hemodynamics and extravascular lung water were observed.
Results: After resuscitation, all the solutions improved the hemodynamics of septic shock dogs with significant differences (P<0.05). The effects were superior in HS group and HSS group when compared with in NS group. The extravascular lung water increased in NS group, while no obvious changes were found in the other three groups.
Conclusions: All these four solutions can improve the hemodynamics of septic shock dogs. Small volume hypertonic-hyperoncotic solution has a similar effect in hemodynamics as NS, HS, and HES. Meanwhile, it does not increase the extravascular lung water.

Background: ANDROMEDA-SHOCK 2 is an international, multicenter, randomized controlled trial comparing hemodynamic phenotype-based, capillary refill time-targeted resuscitation in early septic shock to standard care resuscitation to test the hypothesis that the former is associated with lower morbidity and mortality in terms of hierarchal analysis of outcomes.
Objective: To report the statistical plan for the ANDROMEDA--SHOCK 2 randomized clinical trial.
Methods: We briefly describe the trial design, patients, methods of randomization, interventions, outcomes, and sample size.

We report a first case of ceftazidime-resistant pediatric melioidosis involving a previously healthy seven-year-old boy who presented with right lobar pneumonia complicated with a 5-cm lung abscess. Ceftazidime was initiated on Day-6 of admission when (ceftazidime-susceptible, minimum inhibitory concentration [MIC] 1.0 mcg/mL) was isolated from blood.

The morbidity and mortality of sepsis remain high. Clinicians lack effective markers to rapidly diagnose sepsis and identify the underlying pathogen infection particularly for patients with candidaemia or cases of culture-negative sepsis where culture-based diagnostics are inadequate. In our search for new lines of potential sepsis biomarkers, we here explore the impact of various classes of infectious agents on the serum -glycome in a septic shock cohort.

Background: This study investigates the correlation between the difference in hematocrit (HCT) and serum albumin (ALB) levels (HCT-ALB), muscle tissue oxygen saturation (SmtO2), capillary refill time (CRT), and blood lactate (Lac) with the severity of renal function damage and prognosis in patients with septic shock.
Methods: Conducted from February 2022 to February 2024, this study included 116 septic shock patients treated at the First Affiliated Hospital of Anhui Medical University. Patients were divided into groups based on whether they developed acute kidney injury: 40 patients were included in the acute kidney injury group, and the remaining 76 were placed in the non-kidney injury group.
