Resuscitation Fluid

Septic shock is the most serious complication of sepsis, leading to unacceptably high morbidity and mortality worldwide. Fluid resuscitation using crystalloids has become the mainstay of early and aggressive treatment of severe sepsis and septic shock, while increased daily fluid balances from day 2 until day 7 have been related with increased mortality. Recently, pharmacological management has been recommended to combine with appropriate fluid resuscitation for the treatment of septic shock. In this study, we compared the clinical efficacy of restricting volumes of resuscitation fluid strategy with or without intravenous infusion of ulinastatin (UTI) in treating patients with septic shock and additionally examined the patient’s changes of the extravascular lung water index (EVLWI), pulmonary vascular permeability index (PVPI), systemic vascular resistance index (SVRI), cardiac function, lactic acid (LA) level, coagulation function, and renal function. The study included 182 patients with septic shock, among which 89 patients had undergone restricting volumes of resuscitation fluid strategy with intravenous infusion of UTI and 93 patients had undergone restricting volumes of resuscitation fluid strategy alone. It was found that patients with septic shock after restricting volumes of resuscitation fluid strategy with intravenous infusion of UTI showed an increased SVRI concomitant with declined PVPI and EVLWI, increased mean artery pressure (MAP), cardiac output (CO), left ventricular ejection fraction (LVEF), stroke volume (SV), and heart rate (HR), declined levels of cardiac troponin I (cTnI), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and C-reactive protein (CRP), reduced LA level along with shortened prothrombin time (PT) and partially activated thrombin time (PATT), and decreased levels of blood urea nitrogen (BUN), creatinine (Cr), and uric acid (UA) when comparable to those after restricting volumes of resuscitation fluid strategy alone ( P < 0.05 ). We also observed fewer scores of the Acute Physiology and Chronic Health Evaluation (APACHE II) and the sequential organ failure assessment (SOFA) in patients undergoing restricting volumes of resuscitation fluid strategy with intravenous infusion of UTI than those undergoing restricting volumes of resuscitation fluid strategy alone ( P < 0.05 ). According to the above data, it is concluded that UTI as an adjuvant therapy for restricting volumes of resuscitation fluid strategy in treating septic shock may decrease the LA level, attenuate the inflammatory response, reduce vascular permeability, prevent pulmonary edema, and restore cardiac and renal functions.

Abstract Burn injury is a leading cause of unintentional death and injury in children, with the majority being minor (less than 10%). However, a significant number of children sustain burns greater than 15% total body surface area (TBSA), leading to the initiation of the systemic inflammatory response syndrome. These patients require IV fluid resuscitation to prevent burn shock and death. Prompt resuscitation is critical in pediatric patients due to their small circulating blood volumes. Delays in resuscitation can result in increased complications and increased mortality. The basic principles of resuscitation are the same in adults and children, with several key differences. The unique physiologic needs of children must be adequately addressed during resuscitation to optimize outcomes. In this review, we will discuss the history of fluid resuscitation, current resuscitation practices, and future directions of resuscitation for the pediatric burn population.

The syndrome of neurogenic pulmonary edema raises the question of whether there are neurological influences on pulmonary vascular permeability. Previous experimental models commonly produced severe hemodynamic alterations, complicating the distinction of increased permeability from increased hydrostatic forces in the formation of the pulmonary edema. Accordingly, we employed a milder central nervous system insult and measured the pulmonary vascular protein extravasation rate, which is a sensitive and specific indicator of altered protein permeability. After elevating intracranial pressure via cisternal saline infusion in anesthetized dogs, we used a dual isotope method to measure the protein leak index. This elevated intracranial pressure resulted in a nearly three-fold rise in the protein leak index (54.1 +/- 7.5 vs. 20.2 +/- 0.9). This central nervous system insult was associated with only mild increases in pulmonary arterial pressures and cardiac output. However, when we reproduced these hemodynamic changes with left atrial balloon inflation or isoproterenol infusion, we observed no effect on the protein leak index compared with control. Although the pulmonary arterial wedge pressure with intracranial pressure remained <10 mmHg, increases in the extravascular lung water were demonstrated. The results suggest the existence of neurological influences on pulmonary vascular protein permeability. We conclude that neurological insults result in increase pulmonary vascular permeability to protein and subsequent edema formation, which could not be accounted for by hemodynamic changes alone.

BackgroundOptimal fluid resuscitation in children with major burns is crucial to prevent or minimise burn shock and prevent complications of over-resuscitation.ObjectivesTo identify studies using endpoints to guide fluid resuscitation in children with burns, review the range of reported endpoint targets and assess whether there is evidence that targeted endpoints impact on outcome.DesignSystematic review.MethodsMedline, Embase, Cinahl and the Cochrane Central Register of Controlled Trials databases were searched with no restrictions on study design or date. Search terms combined burns, fluid resuscitation, endpoints, goal-directed therapy and related synonyms. Studies reporting primary data regarding children with burns (<16 years) and targeting fluid resuscitation endpoints were included. Data were extracted using a proforma and the results were narratively reviewed.ResultsFollowing screening of 777 unique references, 7 studies fulfilled the inclusion criteria. Four studies were exclusively paediatric. Six studies used urine output (UO) as the primary endpoint. Of these, one set a minimum UO threshold, while the remainder targeted a range from 0.5–1.0 mL/kg/hour to 2–3 mL/kg/hour. No studies compared different UO targets. Heterogeneous study protocols and outcomes precluded comparison between the UO targets. One study targeted invasive haemodynamic variables, but this did not significantly affect patient outcome.ConclusionsFew studies have researched resuscitation endpoints for children with burns. Those that have done so have investigated heterogeneous endpoints and endpoint targets. There is a need for future randomised controlled trials to identify optimal endpoints with which to target fluid resuscitation in children with burns.
