The following keywords were used: "surgery", "anaesthesia", "anesthesia", "anesthesiology", "anaesthesiology", "fluids", "fluid therapy", "crystalloid", "saline", "plasma-Lyte", "plasmalyte", "hartmann's", "ringers" "acetate", "gluconate", "malate", "lactate". All relevant articles were accessed in full. We summarized the data and reported the data in tables and text. RESULTS We retrieved 104 articles relevant to the choice of Plasma-Lyte 148 for fluid intervention in critical illness, surgery and perioperative medicine. We analyzed the data and reported the results in tables and text.CONCLUSION Plasma-Lyte 148 is an isotonic, buffered intravenous crystalloid solution with a physiochemical composition that closely reflects human plasma. Emerging data supports the use of buffered crystalloid solutions in preference to saline in improving physicochemical outcomes. Further large randomized controlled trials assessing the comparative effectiveness of PlasmaLyte 148 and other crystalloid solutions in measuring clinically important outcomes such as morbidity and mortality are needed.展开更多

Evidence-based recommendations to guide perioperative fluid management are currently limited. Therefore, we provide a contemporary clinical integrative overview of the fundamental principles underpinning fluid intervention and hemodynamic optimization for adult patients undergoing major hepatic resection. DATA SOURCES: A literature review was performed of MEDLINE, EMBASE and the Cochrane Central Registry of Controlled Trials using the terms 'surgery', 'anesthesia', 'starch', 'hydroxyethyl starch derivatives', 'albumin', 'gelatin', 'liver resection', 'hepatic resection', 'fluids', 'fluid therapy', 'crystalloid', 'colloid', 'saline', 'plasma-Lyte', 'plasmalyte', 'hartmann's', 'acetate', and 'lactate'. Search results for MEDLINE and EMBASE were additionally limited to studies on human populations that included adult age groups and publications in English. RESULTS: A total of 113 articles were included after appropriate inclusion criteria screening. Perioperative fluid management as it relates to various anesthetic and surgical techniques is discussed.CONCLUSIONS: Clinicians should have a fundamental understanding of the surgical phases of the resection, hemodynamic goals, and anesthesia challenges in attempts to individualize therapy to the patient's underlying pathophysiological condition. Therefore, an ideal approach for perioperative fluid therapy is always individualized. Planning and designing large-scale clinical trials are imperative to define the optimal type and amount of fluid for patients undergoing major hepatic resection. Further clinical trials evaluating different intraoperative goal-directed strategies are also eagerly awaited.展开更多

In this review, recent insights derived from randomized trials in terms of fluid type, dose and toxicity are discussed. We contend that the prescription of fluid therapy is context-specific and that any fluid can be harmful if administered inappropriately. When contrasting ‘‘crystalloid vs colloid'', differences in efficacy are modest but differences in safety are significant. Differences in chloride load and strong ion difference across solutions appear to be clinically important. Phases of fluid therapy in acutely ill patients are recognized, including acute resuscitation, maintaining homeostasis, and recovery phases. Quantitative toxicity(fluid overload) is associated with adverse outcomes and can be mitigated when fluid therapy basedon functional hemodynamic parameters that predict volume responsiveness and minimization of non-essential fluid. Qualitative toxicity(fluid type), in particular for iatrogenic acute kidney injury and metabolic acidosis, remain a concern for synthetic colloids and isotonic saline, respectively. Physiologically balanced crystalloids may be the ‘‘default'' fluid for acutely ill patients and the role for colloids, in particular hydroxyethyl starch, is increasingly unclear. We contend the prescription of fluid therapy is analogous to the prescription of any drug used in critically ill patients.展开更多

The selected patients were randomly divided into three groups: sodium lactate Ringer's solution group (LR group), saline group (NS group) and compound sodium chloride injection group (RS group), each group received the corresponding crystal liquid for fluid resuscitation, compare three groups Heart rate (HR), mean arterial pressure (MAP), cardiac output, procalcitonin (PCT), and C-reactive protein (CRP) before and after treatment, compared with the treatment of 24 hours of lactate clearance and APACHE II scores, and the overall hospitalization time and mortality rate of the three groups of patients were statistically compared;Results: (1) The difference of HR, MAP and cardiac output between the three groups before treatment was not statistically significant (P>0.05), treatment for 24h The HR of the post-Lactate Ringer's solution group was lower than that of the control group, and the MAP and cardiac output were higher than the control group (P<0.05). (2) The difference of PCT, CRP and BNP levels between the three groups before and after treatment was not statistically significant. (P>0.05);(3) Compared with the results, there was no statistically significant difference in the clearance rate of lactate clearance between the three groups (P>0.05). Three groups before and after treatment APACHE II score was not statistically significant difference comparison (P> 0.05). (4) Three groups The overall hospitalization time and mortality rate of the patients were not statistically significant (P>0.05). Conclusion: Lactate Ringer's solution can better maintain the circulation capacity and blood pressure, which can alleviate the clinical symptoms of patients with septic shock, but no obvious effect on lactic acid clearance. The effect of resuscitation with clinically available crystalloid sodium lactate Ringer's solution, saline and compound sodium chloride injection was not statistically significant in patients with septic shock.展开更多
