Recipient pre-existing chronic hypotension is associated with delayed graft function and inferior graft survival in kidney transplantation from elderly donors. PLoS One 2021; 16:e0249552. [PMID: 33819285 PMCID: PMC8021200 DOI: 10.1371/journal.pone.0249552] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Accepted: 03/20/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Pre-existing chronic hypotension affects a percentage of kidney transplanted patients (KTs). Although a relationship with delayed graft function (DGF) has been hypothesized, available data are still scarce and inconclusive. METHODS A monocentric retrospective observational study was performed on 1127 consecutive KTs from brain death donors over 11 years (2003-2013), classified according to their pre-transplant Mean Blood Pressure (MBP) as hypotensive (MBP < 80 mmHg) or normal-hypertensive (MBP ≥ 80 mmHg, with or without effective antihypertensive therapy). RESULTS Univariate analysis showed that a pre-existing hypotension is associated to DGF occurrence (p<0.01; OR for KTs with MBP < 80 mmHg, 4.5; 95% confidence interval [CI], 2.7 to 7.5). Chronic hypotension remained a major predictive factor for DGF development in the logistic regression model adjusted for all DGF determinants. Adjunctive evaluations on paired grafts performed in two different recipients (one hypotensive and the other one normal-hypertensive) confirmed this assumption. Although graft survival was only associated with DGF but not with chronic hypotension in the overall population, stratification according to donor age revealed that death-censored graft survival was significantly lower in hypotensive patients who received a KT from >50 years old donor. CONCLUSIONS Our findings suggest that pre-existing recipient hypotension, and the subsequent hypotension-related DGF, could be considered a significant detrimental factor, especially when elderly donors are involved in the transplant procedure.

Abstract
PURPOSE The aim of this study was to investigate two clinically approved plasma volume expanders (dextran 70 and voluven) as macromolecular MRI-chemical exchange saturation transfer (CEST) contrast agents to assess tumor vascular properties. METHODS CEST contrast efficiency of both molecules (6% w/v) was measured in vitro at various irradiation saturation powers (1-6 μT for 5 s) and pH values (range, 5.5-7.9) and the exchange rate of hydroxyl protons was calculated. In vivo studies in a murine adenocarcinoma model (n = 4 mice for each contrast agent) upon i.v. injection provided CEST-derived perfusion tumor properties that were compared with those obtained with a gadolinium-based blood-pool agent (Gd-AAZTA-Madec). RESULTS In vitro measurements showed a marked CEST contrast dependency to pH, with higher CEST contrast at lower pH values for both molecules. The measured prototropic exchange rates confirmed a base-catalyzed exchange rate that was faster for dextran 70 in comparison to voluven. Both molecules showed a similar CEST contrast increase (ΔST% > 3%) in the tumor tissue up to 30 min postinjection, with heterogeneous accumulation. In tumors receiving both CEST and T1 -weighted agents, a voxel-by-voxel analysis indicated moderate spatial correlation of perfusion properties between voluven/dextran 70 and Gd-AAZTA-Madec, suggesting different distribution patterns according to their molecular size. CONCLUSIONS The obtained results showed that both voluven and dextran 70 can be exploited as MRI-CEST contrast agents for evaluating tumor enhancement properties. Their increased accumulation in tumors and prolonged contrast enhancement promote their use as blood-pool MRI-CEST agents to examine tumor vascularization.

Abstract
Objectives This multicenter retrospective study aimed to compare the effects of HES and gelatin (GEL) on the risk of post-OLT AKI. Method A total of 1,672 patients undergoing OLT were enrolled from major transplant centers in China between 2005 and 2013. These patients were divided into three groups: GEL, hydroxyethyl starch (HES), and GEL + HES group. Results There was no significant difference in the incidence of post-OLT AKI among the GEL, HES, and GEL + HES groups. The GEL + HES group had a lower incidence of stage II post-OLT AKI than the other two groups. Compared with patients receiving GEL, patients receiving HES did not harbor an increased risk of AKI. Our results showed that MELD score (adjusted odds ratio [OR], 1.579; 95% confidence interval [CI], 1.123–2.219; P = 0.009) and preoperative anemia (adjusted OR, 1.533; 95% CI, 1.212–1.939; P < 0.001) were independent risk factors for post-OLT AKI, and normal preoperative Scr level (vs abnormal; adjusted OR, 0.402; 95% CI, 0.222–0.729; P = 0.003) was independent protective factors for post-OLT AKI. Conclusion This large-scale multicenter retrospective study found that the intraoperative use of HES did not increase the overall incidence of post-OLT AKI in patients when compared with GEL, and whether to increase the risk of post-OLT AKI needs to be further explored.

Abstract
Background Fluids are by far the most commonly administered intravenous treatment in patient care. During critical illness, fluids are widely administered to maintain or increase cardiac output, thereby relieving overt tissue hypoperfusion and hypoxia. Main text Until recently, because of their excellent safety profile, fluids were not considered “medications”. However, it is now understood that intravenous fluid should be viewed as drugs. They affect the cardiovascular, renal, gastrointestinal and immune systems. Fluid administration should therefore always be accompanied by careful consideration of the risk/benefit ratio, not only of the additional volume being administered but also of the effect of its composition on the physiology of the patient. Apart from the need to constantly assess fluid responsiveness, it is also important to periodically reconsider the type of fluid being administered and the evidence regarding the relationship between specific disease states and different fluid solutions. Conclusions The current review presents the state of the art regarding fluid solutions and presents the existing evidence on routine fluid management of critically ill patients in specific clinical settings (sepsis, Adult Respiratory Distress Syndrome, major abdominal surgery, acute kidney injury and trauma). Electronic supplementary material The online version of this article (10.1186/s12871-018-0669-3) contains supplementary material, which is available to authorized users.

Abstract
This article reviews the pathophysiology of large burn injury and the extreme fluid shifts that occur in the hours and days after this event. The authors focus on acute fluid management, monitoring of hemodynamic status, and end points of resuscitation. Understanding the need and causes for fluid resuscitation after burn injury helps the clinician develop an effective plan to balance the competing goals of normalized tissue perfusion and limited tissue edema. Thoughtful, individualized treatment is the best answer and the most effective compromise.

Abstract
OBJECTIVE Intravenous fluids are broadly categorized into colloids and crystalloids. The aim of this review is to present under a clinical point of view the characteristics of intravenous fluids that make them more or less appropriate either for maintaining hydration when enteral intake is contraindicated or for treating hypovolemia. METHODS We considered randomized trials and meta-analyses as well as narrative reviews evaluating the effects of colloids or crystalloids in patients with hypovolemia or as maintenance fluids published in the PubMed and Cochrane databases. RESULTS Clinical studies have not shown a greater clinical benefit of albumin solutions compared with crystalloid solutions. Furthermore, albumin and colloid solutions may impair renal function, while there is no evidence that the administration of colloids reduces the risk of death compared with resuscitation with crystalloids in patients with trauma, burns or following surgery. Among crystalloids, normal saline is associated with the development of hyperchloremia-induced impairment of kidney function and metabolic acidosis. On the other hand, the other commonly used crystalloid solution, the Ringer's Lactate, has certain indications and contraindications. These matters, along with the basic principles of the administration of potassium chloride and bicarbonate, are meticulously discussed in the review. CONCLUSIONS Intravenous fluids should be dealt with as drugs, as they have specific clinical indications, contraindications and adverse effects.

Abstract
Background: This retrospective study examined the effectiveness and safety of polygeline in adult patients with hypovolemia due to traumatic injury. Materials and Methods: Polygeline was administered after evaluating the amount of blood loss and estimating hematological and biochemical parameters. Changes in vital signs, serum electrolytes, arterial pH, and serum lactate were evaluated. The safety was evaluated by recording the adverse events if any. Results: Sixty patients with the mean age 37.5 ± 11.26 years were included in the study. All patients had blood loss < 20%. The mean total polygeline administered was 1025.0 ± 464.18 ml. Blood transfusion was required in 3.33% of patients. Diastolic, systolic, and mean arterial blood pressure and pulse rate significantly increased after 1 h of polygeline administration (P < 0.0001). There was a trend toward increase in urine output (P = 0.0715) after 1 h. The improvement in vital parameters was consistent at 6, 14, and 18 h after administration of polygeline. Arterial pH significantly increased from 7.2 ± 0.12 to 7.3 ± 0.11 after 1 h of administration (P < 0.0001) and was consistent till 24 h (P = 0.035). Blood lactate decreased after 1 h (P < 0.0001). Changes in laboratory parameters were not clinically significant. After mean duration hospital stay of 10.5 ± 4.63 days all patients were discharged without any clinically significant abnormality or adverse event. Conclusion: Polygeline improved hemodynamic stability in patients with hypovolemia due to traumatic injury. The improvement was seen within 1 h (golden hour) of polygeline administration and maintained consistently. Polygeline can be safely administered to patients with traumatic injury to improve hemodynamic parameters and achieve stability.

Abstract
Perioperative medical management of patients undergoing vascular surgery can be challenging because they represent the surgical population at highest risk. β-Blockers should be continued perioperatively in patients already taking them preoperatively. Statins may be used in the perioperative period in patients who are not on statin therapy preoperatively. Institutional guidelines should be used to guide insulin replacement. Recent research suggests that measurement of troponins may provide some risk stratification in clinically stable patients following vascular surgery. Multimodal pain therapy including nonopioid strategies is necessary to improve the efficacy of pain relief and decrease the risk of side effects and complications.

Abstract
INTRODUCTION While neonates account for a significant proportion of health care expenditures related to inpatient care for congenital heart disease, key drivers of resource utilization among this population are poorly defined. METHODS Data from 2005 through 2011 were extracted from the Pediatric Health Information System for patients assigned a discharge All Patient Refined Diagnosis Related Group of 630 (neonates with birthweight >2499 g undergoing a major cardiovascular procedure). Mortality risk adjustment for patients undergoing operative interventions was performed with the Risk Adjusment in Congenital Heart Surgery (RACHS-1) score. RESULTS A total of 13 156 cases were included in the analysis. Despite only a 3% increase in case mix index and no significant change in operative acuity over the study period (RACHS classifications of 3 or greater 67% in 2005 vs. 66% in 2011, P = .64), there were inflation-adjusted increases in both total estimated cost per case of (50% to $151 760 in 2011, P < .001), and mean charge per case (33% to $433 875 in 2011, P < .001). Pharmacy charges increased by 16% (P < .001), with agents including chlorothiazide and albumin accounting for the highest patient charges over the study period. Imaging charges increased by 42% (P < .001), with an average of 5.7 echocardiograms and $6517 in associated charges per case by 2011. While the proportion of patients receiving nitric oxide remained consistent, mean duration of administration increased by 25% to 6.6 days by 2011, accounting for average charges of $52 141 per patient exposed. CONCLUSIONS Among neonates with serious congenital heart disease, increases in both institutional costs and charges to the patient are associated with relatively consistent utilization practices in recent years. Multiinstitutional collaboration may prove useful in aligning evidence-based reductions in practice variation with limitations in resource utilization without compromising the quality of care.

Abstract
PURPOSE To assess the impact of 6% tetrastarch [hydroxyethyl starch (HES) 130/0.4 and 130/0.42] in severe sepsis patients. The primary outcome measure was 90-day mortality. METHODS A structured literature search was undertaken to identify prospective randomised controlled trials (RCTs) in adult patients with severe sepsis receiving 6% tetrastarch (of potato or waxy maize origin) as part of fluid resuscitation in comparison with other non-HES fluids after randomisation in the critical care setting. A systematic review and meta-analysis were performed. RESULTS Six RCTs were included (n = 3,033): three from 2012 (n = 2,913) had low risk of bias. Median tetrastarch exposure was 37.4 ml/kg (range 30-43 ml/kg). Ninety-day mortality was associated with tetrastarch exposure [relative risk (RR) 1.13; 95% confidence interval (CI) 1.02-1.25; p = 0.02] compared with crystalloid. The number needed to harm (NNH) was 28.8 (95 % CI 14.6-942.5). Publication bias and statistical heterogeneity (I(2) = 0%) were not present. Tetrastarch exposure was also associated with renal replacement therapy (p = 0.01; NNH 15.7) and allogeneic transfusion support (p = 0.001; NNH 9.9). No difference between groups was observed for 28-day mortality, for comparison with colloid as control, or for waxy maize-derived tetrastarch, but power was lacking. Overall mortality was associated with tetrastarch exposure (RR 1.13; 95% CI 1.02-1.25; p = 0.02). CONCLUSIONS In our analysis, 6% tetrastarch as part of initial fluid resuscitation for severe sepsis was associated with harm and, as alternatives exist, in our view should be avoided.

STUDY SELECTION Eligible trials were randomised clinical trials comparing hydroxyethyl starch 130/0.38-0.45 with either crystalloid or human albumin in patients with sepsis. Published and unpublished trials were included irrespective of language and predefined outcomes. DATA EXTRACTION Two reviewers independently assessed studies for inclusion and extracted data on methods, interventions, outcomes, and risk of bias. Risk ratios and mean differences with 95% confidence intervals were estimated with fixed and random effects models. RESULTS Nine trials that randomised 3456 patients with sepsis were included. Overall, hydroxyethyl starch 130/0.38-0.45 versus crystalloid or albumin did not affect the relative risk of death (1.04, 95% confidence interval 0.89 to 1.22, 3414 patients, eight trials), but in the predefined analysis of trials with low risk of bias the relative risk of death was 1.11 (1.00 to 1.23, trial sequential analysis (TSA) adjusted 95% confidence interval 0.95 to 1.29, 3016 patients, four trials). In the hydroxyethyl starch group, renal replacement therapy was used more (1.36, 1.08 to 1.72, TSA adjusted 1.03 to 1.80, 1311 patients, five trials), and the relative risk of acute kidney injury was 1.18 (0.99 to 1.40, TSA adjusted 0.90 to 1.54, 994 patients, four trials). More patients in the hydroxyethyl starch group were transfused with red blood cells (1.29, 1.13 to 1.48, TSA adjusted 1.10 to 1.51, 973 patients, three trials), and more patients had serious adverse events (1.30, 1.02 to 1.67, TSA adjusted 0.93 to 1.83, 1069 patients, four trials). The transfused volume of red blood cells did not differ between the groups (mean difference 65 mL, 95% confidence interval -20 to 149 mL, three trials). CONCLUSION In conventional meta-analyses including recent trial data, hydroxyethyl starch 130/0.38-0.45 versus crystalloid or albumin increased the use of renal replacement therapy and transfusion with red blood cells, and resulted in more serious adverse events in patients with sepsis. It seems unlikely that hydroxyethyl starch 130/0.38-0.45 provides overall clinical benefit for patients with sepsis.

Fluid resuscitation with 6 % hydroxyethyl starch (130/0.4 and 130/0.42) in acutely ill patients: systematic review of effects on mortality and treatment with renal replacement therapy. Intensive Care Med 2013; 39:558-68. [PMID: 23407978 DOI: 10.1007/s00134-013-2840-0] [Citation(s) in RCA: 107] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2012] [Accepted: 01/11/2013] [Indexed: 12/26/2022]
Abstract
PURPOSE To determine whether fluid resuscitation of acutely ill adults with 6 % hydroxyethyl starch (6 % HES 130) with a molecular weight of 130 kD and a molar substitution ratio of approximately 0.4 (6 % HES 130) compared with other resuscitation fluids results in a difference in the relative risk of death or treatment with renal replacement therapy (RRT). METHODS Systematic review and meta-analysis of randomized controlled trials comparing intravascular fluids for resuscitation of hospitalised adults that reported mortality or treatment with RRT. The risk of bias was assessed independently by two reviewers and meta-analysis was performed using random effects. RESULTS Thirty-five trials enrolling 10,391 participants were included. The three largest trials had the lowest risk of bias, were published (or completed) in 2012, and together enrolled 77 % of all participants. Death occurred in 928 of 4,691 patients (19.8 %) in the 6 % HES 130 group versus 871 of 4,720 (18.5 %) in the control fluid groups relative risk (RR) in the 6 % HES 130 group 1.08, 95 % confidence interval (CI) 1.00 to 1.17, I (2) = 0 %). Treatment with RRT occurred in 378 of 4,236 patients (8.9 %) in the 6 % HES 130 group versus 306 of 4,260 (7.2 %) in the control fluid group (RR in the 6 % HES 130 group 1.25, 95 % CI 1.08 to 1.44, I (2) = 0 %). CONCLUSIONS The quality and quantity of data evaluating 6 % hydroxyethyl starch (130/0.4 and 130/0.42) as a resuscitation fluid has increased in the last 12 months. Patients randomly assigned to resuscitation with 6 %HES 130 are at significantly increased risk of being treated with RRT.

Abstract
<b><i>Hintergrund: </i></b>Intraoperative Gerinnungsstörungen kommen bei großen Operationen häufig vor und können verschiedene, oft parallel auftretende Ursachen haben. Die Blutungsdynamik unter laufender Operation erfordert eine gute interdisziplinäre Zusammenarbeit sowie ein effektives Team- und Kontextmanagement. Geeignete diagnostische Methoden sind für ein rasches und zielgerichtetes Gerinnungsmanagement notwendig. <b><i>Methode: </i></b>Die Literatur bis April 2013 wurde selektiv, inklusive der neuen europäischen und deutschen anästhesiologischen Handlungsempfehlungen zum perioperativen Blutungsmanagement, berücksichtigt. <b><i>Ergebnisse: </i></b>Dilutionskoagulopathien zählen zu den häufigsten intraoperativen Gerinnungsstörungen, da bei Blutverlust zur Aufrechterhaltung der Makrozirkulation kolloidale oder kristalloide Lösungen infundiert bzw. Erythrozytenkonzentrate zur Oxygenierung transfundiert werden. Hypothermien, Azidosen, Hypocalciämien, Anämien, Hyperfibrinolysen, Medikamenteneinnahmen und Vorerkrankungen können die Koagulopathien verstärken. Fibrinogen ist der erste Faktor, der bei massiven Blutungen kritisch abfällt und substituiert werden muss. <b><i>Schlussfolgerungen: </i></b>Patientennahe diagnostische Verfahren eignen sich besonders zur Differenzierung von intraoperativen Gerinnungsstörungen und einer zielgerichteten Therapie. Faktorenkonzentrate stehen schneller als Gefrierplasmen (fresh frozen plasma, FFP) zur Verfügung und bilden häufig die Basis einer zielgerichteten Therapie. FFP enthalten alle Faktoren in einem physiologischen Verhältnis, allerdings unkonzentriert. Zu den Limitationen zählen neben geringerer Wirksamkeit die zeitaufwendige Vorbereitung und die nicht unerheblichen unerwünschten Wirkungen. Die Evidenzlage ist noch nicht ausreichend für eindeutige Empfehlungen.
