Szabó GV, Szigetváry C, Turan C, Engh MA, Terebessy T, Fazekas A, Farkas N, Hegyi P, Molnár Z. Fluid resuscitation with balanced electrolyte solutions results in faster resolution of diabetic ketoacidosis than with 0.9% saline in adults - A systematic review and meta-analysis. Diabetes Metab Res Rev 2024; 40:e3831. [PMID: 38925619 DOI: 10.1002/dmrr.3831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 02/12/2024] [Accepted: 05/31/2024] [Indexed: 06/28/2024]
Abstract
Fluid resuscitation during diabetic ketoacidosis (DKA) is most frequently performed with 0.9% saline despite its high chloride and sodium concentration. Balanced Electrolyte Solutions (BES) may prove a more physiological alternative, but convincing evidence is missing. We aimed to compare the efficacy of 0.9% saline to BES in DKA management. MEDLINE, Cochrane Library, and Embase databases were searched for relevant studies using predefined keywords (from inception to 27 November 2021). Relevant studies were those in which 0.9% saline (Saline-group) was compared to BES (BES-group) in adults admitted with DKA. Two reviewers independently extracted data and assessed the risk of bias. The primary outcome was time to DKA resolution (defined by each study individually), while the main secondary outcomes were changes in laboratory values, duration of insulin infusion, and mortality. We included seven randomized controlled trials and three observational studies with 1006 participants. The primary outcome was reported for 316 patients, and we found that BES resolves DKA faster than 0.9% saline with a mean difference (MD) of -5.36 [95% CI: -10.46, -0.26] hours. Post-resuscitation chloride (MD: -4.26 [-6.97, -1.54] mmoL/L) and sodium (MD: -1.38 [-2.14, -0.62] mmoL/L) levels were significantly lower. In contrast, levels of post-resuscitation bicarbonate (MD: 1.82 [0.75, 2.89] mmoL/L) were significantly elevated in the BES-group compared to the Saline-group. There was no statistically significant difference between the groups regarding the duration of parenteral insulin administration (MD: 0.16 [-3.03, 3.35] hours) or mortality (OR: -0.67 [0.12, 3.68]). Studies showed some concern or a high risk of bias, and the level of evidence for most outcomes was low. This meta-analysis indicates that the use of BES resolves DKA faster than 0.9% saline. Therefore, DKA guidelines should consider BES instead of 0.9% saline as the first choice during fluid resuscitation.

Abstract
The American Diabetes Association (ADA), European Association for the Study of Diabetes (EASD), Joint British Diabetes Societies for Inpatient Care (JBDS), American Association of Clinical Endocrinology (AACE) and Diabetes Technology Society (DTS) convened a panel of internists and diabetologists to update the ADA consensus statement on hyperglycaemic crises in adults with diabetes, published in 2001 and last updated in 2009. The objective of this consensus report is to provide up-to-date knowledge about the epidemiology, pathophysiology, clinical presentation, and recommendations for the diagnosis, treatment and prevention of diabetic ketoacidosis (DKA) and hyperglycaemic hyperosmolar state (HHS) in adults. A systematic examination of publications since 2009 informed new recommendations. The target audience is the full spectrum of diabetes healthcare professionals and individuals with diabetes.

Abstract
Background: Patients with diabetic ketoacidosis (DKA) are transitioned from intravenous (IV) to subcutaneous (SQ) insulin upon DKA resolution. Although an anion gap (AG) ≤12 mEq/L is recommended before transition to SQ insulin, there are limited data to support this threshold. Objective: To compare the rates of successful transitions to SQ insulin in patients with DKA with an AG ≤ 12 mEq/L versus > 12 mEq/L. Methods: Retrospective cohort study of adult critically ill patients with moderate to severe DKA between September 2019 and December 2022. The primary outcome was the success of insulin transition between patients transitioned with an AG ≤ 12 mEq/L and those transitioned with an AG > 12 mEq/L. Transition was considered successful if the AG did not increase above the value at transition at 24 hours and insulin infusion was not restarted. Secondary outcomes include the individual components of the primary outcome and ICU length of stay (LOS); safety outcomes included hypoglycemia and electrolyte derangements. Results: In total, 92 patients were included, with 43 patients transitioned at AG ≤ 12 mEq/L and 49 patients transitioned at AG > 12 mEq/L. Transition was unsuccessful in 3 patients (7%) with AG ≤ 12 mEq/L and 2 patients (4%) with AG > 12 mEq/L (P = .66). There was no difference in the incidence of the individual components of this outcome between groups or in safety outcomes. Conclusion: This retrospective study showed no difference in success of insulin transition between the groups. Larger studies are needed to evaluate the impact of treatment characteristics on transition success and patient outcomes.

Abstract
BACKGROUND Current guidelines recommend normal saline (NS) for fluid resuscitation in the management of patients presenting with diabetic ketoacidosis (DKA). However, previous prospective studies have demonstrated improvement in patient-specific outcomes, including time to DKA resolution, when balanced crystalloid fluids are used. METHODS We conducted a single institution, retrospective cohort study of adult patients admitted with DKA before and after a protocol change within our institution, which shifted the default resuscitative and maintenance fluid in our DKA management protocol from NS to lactated Ringer's solution (LR). The primary outcome was time from DKA clinical presentation until DKA resolution. The secondary outcome was time to discontinuation of DKA protocol insulin drip. RESULTS Of 246 patients meeting inclusion criteria, 119 were in the NS group (preprotocol change, where NS was the default resuscitative fluid) and 127 to the LR group (postprotocol change, where LR was the default resuscitative fluid). Time to DKA resolution was significantly decreased in the LR group (mean = 17.1 hours; standard deviation [SD] = 11.0) relative to the NS group (mean = 20.6 hours; SD = 12.2; P = .02). Duration of DKA protocol insulin drip was shorter in the LR group (mean = 16.0 hours; SD = 8.7) compared with the NS group (mean = 21.4 hours; SD = 12.5; P < .001). CONCLUSIONS In this retrospective cohort study, protocolized DKA intravenous fluid management with LR resulted in shorter time to resolution of DKA and reduced duration of DKA protocol insulin drip.

Pediatr Nephrol 2024; 39:889-896.

Abstract
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.

Abstract
PURPOSE OF REVIEW To evaluate recent evidence (2021-2023) on fluid therapy in diabetic ketoacidosis. Key evidence gaps which require generation of new evidence are discussed. RECENT FINDINGS Balanced crystalloid solutions, compared to the commonly recommended and used 0.9% sodium chloride solution (saline), may result in better outcomes for patients with diabetic ketoacidosis, including faster resolution of acidosis, less hyperchloremia and shorter hospital length of stay. Upcoming results from randomized trials may provide definitive evidence on the use of balanced crystalloid solutions in diabetic ketoacidosis. Evidence remains scarce or conflicting for the use of "two-bag" compared to conventional "one-bag" fluid, and rates of fluid administration, especially for adult patients. In children, concerns about cerebral oedema from faster fluid administration rates have not been demonstrated in cohort studies nor randomized trials. SUMMARY Fluid therapy is a key aspect of diabetic ketoacidosis management, with important evidence gaps persisting for several aspects of management despite recent evidence.

Abstract
Sepsis is a clinical syndrome encompassing physiologic and biological abnormalities caused by a dysregulated host response to infection. Sepsis progression into septic shock is associated with a dramatic increase in mortality, hence the importance of early identification and treatment. Over the last two decades, the definition of sepsis has evolved to improve early sepsis recognition and screening, standardize the terms used to describe sepsis and highlight its association with organ dysfunction and higher mortality. The early 2000s witnessed the birth of early goal-directed therapy (EGDT), which showed a dramatic reduction in mortality leading to its wide adoption, and the surviving sepsis campaign (SSC), which has been instrumental in developing and updating sepsis guidelines over the last 20 years. Outside of early fluid resuscitation and antibiotic therapy, sepsis management has transitioned to a less aggressive approach over the last few years, shying away from routine mixed venous oxygen saturation and central venous pressure monitoring and excessive fluids resuscitation, inotropes use, and red blood cell transfusions. Peripheral vasopressor use was deemed safe and is rising, and resuscitation with balanced crystalloids and a restrictive fluid strategy was explored. This review will address some of sepsis management's most important yet controversial components and summarize the available evidence from the last two decades.

Abstract
OBJECTIVES Normal saline (NS) and Ringer's lactate (RL) are the most common crystalloids used for fluid therapy. Despite evidence of possible harm associated with NS (eg, hyperchloremic metabolic acidosis, impaired kidney function and death), few large multi-centre randomised trials have evaluated the effect of these fluids on clinically important outcomes. We conducted a pilot trial to explore the feasibility of a large trial powered for clinically important outcomes. DESIGN FLUID was a pragmatic pilot cluster randomised cross-over trial. SETTING Four hospitals in the province of Ontario, Canada PARTICIPANTS: All hospitalised adult and paediatric patients with an incident admission to the hospital over the course of each study period. INTERVENTIONS A hospital wide policy/strategy which stocked either NS or RL throughout the hospital for 12 weeks before crossing over to the alternate fluid for the subsequent 12 weeks. PRIMARY AND SECONDARY OUTCOME MEASURES The primary feasibility outcome was study fluid protocol adherence. Secondary feasibility outcomes included time to Research Ethics Board (REB) approval and trial initiation. Primary (composite of death or re-admission to hospital in first 90 days of index hospitalisation) and secondary clinical outcomes were analysed descriptively. RESULTS Among 24 905 included patients, mean age 59.1 (SD 20.5); 13 977 (56.1%) were female and 21 150 (85.0%) had medical or surgical admitting diagnoses. Overall, 96 821 L were administered in the NS arm, and 78 348 L in the RL arm. Study fluid adherence to NS and RL was 93.7% (site range: 91.6%-98.0%) and 79.8% (site range: 72.5%-83.9%), respectively. Time to REB approval ranged from 2 to 48 days and readiness for trial initiation from 51 to 331 days. 5544 (22.3%) patients died or required hospital re-admission in the first 90 days. CONCLUSIONS The future large trial is feasible. Anticipating and addressing logistical challenges during the planning stages will be imperative. TRIAL REGISTRATION NUMBER NCT02721485.

Plasma volume expansion reveals hidden metabolic acidosis in patients with diabetic ketoacidosis. Intensive Care Med Exp 2022; 10:36. [PMID: 36038699 PMCID: PMC9424448 DOI: 10.1186/s40635-022-00464-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Accepted: 08/13/2022] [Indexed: 11/30/2022] Open
Abstract
Background Hyperchloremic metabolic acidosis that develops during the treatment of diabetic ketoacidosis is usually attributed to the chloride content of resuscitation fluids. We explored an alternative explanation, namely that fluid-induced plasma volume expansion alters the absolute differences in the concentrations of sodium and chloride (the Na–Cl gap) enough to affect the acid–base balance. We analyzed data from a prospective single-center cohort study of 14 patients treated for diabetic ketoacidosis. All patients received 1 L of 0.9% saline over 30 min on two consecutive days. Blood gases were sampled before and after the infusions. Results The initial plasma volume was estimated to be 25 ± 13% (mean ± SD) below normal on admission to the intensive care unit. At that time, most patients had an increased actual Na–Cl gap, which counteracts acidosis. However, the correction of the plasma volume deficit revealed that these patients would have had a decreased Na–Cl gap upon admission if they had been normovolemic at that time; the estimated “virtual Na–Cl gap” of 29 ± 5 mmol/L was significantly lower than the uncorrected value, which was 39 ± 5 mmol/L (P < 0.001). On Day 2, most patients had a decreased actual Na–Cl gap (33 ± 5 mmol/L), approaching the corrected value on Day 1. Conclusions The hyperchloremic acidosis commonly seen in diabetic ketoacidosis may not be primarily caused by the chloride content of resuscitation fluids but, rather, by the restoration of plasma volume, which reveals the hidden metabolic acidosis caused by a decreased Na–Cl gap.
