Abstract
CONTEXT The metabolic response to stress can deplete the remaining thiamine stores, leading to thiamine deficiency. OBJECTIVE This study is the first meta-analysis of the effectiveness of thiamine supplementation on clinical and biochemical outcomes in adult patients admitted to the intensive care unit (ICU). DATA SOURCES Scopus, PubMed, and Cochrane databases were searched to select studies up to 20 November 2022. STUDY SELECTION Studies investigating the effect of thiamine supplementation on serum lactate and creatinine levels, the need for renal replacement therapy, length of ICU stay, and mortality rate in ICU patients were selected. DATA EXTRACTION After excluding studies based on title and abstract screening, 2 independent investigators reviewed the full texts of the remaining articles. In the next step, a third investigator resolved any discrepancy in the article selection process. RESULTS Of 1628 retrieved articles, 8 were selected for final analysis. This study showed that thiamine supplementation reduced the serum creatinine level (P = .03) compared with placebo. In addition, according to subgroup analysis, serum creatinine concentration was significantly lower in patients >60 years old (P < .00001). However, there was no statistically significant difference in the lactate level between the thiamine supplementation and placebo groups (P = .26). Thiamine supplementation did not decrease the risk of all-cause mortality (P = .71) or the need for renal replacement therapy (P = .14). The pooled results of eligible randomized controlled trials also showed that thiamine supplementation did not reduce the length of ICU stay in comparison to the placebo group (P = .39). CONCLUSION This meta-analysis provides evidence that thiamine supplementation has a protective effect against blood creatinine increase in ICU patients. However, further high-quality trials are needed to discover the effect of thiamine supplementation on clinical and biochemical outcomes in ICU patients. SYSTEMATIC REVIEW REGISTRATION PROSPERO no.

Odelli AL, Holyoak A, Yadav S, Page SM, Lindsay D. The effect of cardiopulmonary bypass on blood thiamine concentration and its association with post-operative lactate concentration. J Cardiothorac Surg 2022; 17:260. [PMID: 36207738 PMCID: PMC9541071 DOI: 10.1186/s13019-022-02016-0] [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: 03/04/2022] [Accepted: 09/24/2022] [Indexed: 12/04/2022] Open
Abstract
Objective Cardiothoracic surgery is a large field in Australia, and evidence suggests post-cardiopulmonary bypass (CPB) hyperlactataemia is associated with higher morbidity and mortality. Low thiamine levels are a potentially common yet treatable cause of hyperlactataemia and may occur in the setting of exposure to CPB non-biological material. We hypothesized that cardiopulmonary bypass would result in decreased whole-blood thiamine levels, which may therefore result in increased whole-blood lactate levels in the post-operative period. Methods Adult patients undergoing non-emergent CPB were recruited in a single centre, prospective, analytic observational study at Townsville University Hospital, Australia. The primary outcome was a comparison of pre- and post-CPB thiamine diphosphate level, secondarily aiming to assess any relationship between lactate and thiamine levels. Prospective pre- and post-CPB blood samples were taken and analysed at a central reference laboratory. Results Data was available for analysis on 78 patients. There was a statistically significant increase in thiamine diphosphate level from pre-CPB: 1.36 nmol/g Hb, standard deviation (SD) 0.31, 95% confidence intervals (CI) 1.29–1.43, to post-CPB: 1.77 nmol/g Hb, SD 0.53, 95% CI 1.43–1.88, p value < 0.001. There was a non-statistically significant (p > 0.05) trend in rising whole-blood lactate levels with increasing time. Analysis of lactate levels at varying time periods found a significant difference between baseline measurements and increased levels at 13–16 h (p < 0.05). There was no significant relationship observed between whole-blood thiamine levels and post-operative lactate levels. Conclusion Whole-blood thiamine levels were found to increase immediately post-CPB in those undergoing elective cardiac surgery. There was no correlation between whole-blood thiamine levels and post-operative arterial lactate levels.

A meta-analysis of clinical trial studies. J Intensive Care 2022; 10:8. [PMID: 35177121 PMCID: PMC8851730 DOI: 10.1186/s40560-022-00594-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Accepted: 01/04/2022] [Indexed: 01/21/2023] Open
Abstract
Background Although the effect of thiamine alone or in combination with vitamin C has been studied in multiple trials (RCT and interventional studies), their results are inconsistent. This meta-analysis aimed to assess impact of thiamine administration alone, thiamine in combination with vitamin C, and co-administration of low-dose hydrocortisone, vitamin C and thiamine (HVT) on clinical outcomes in critically ill patients. Methods and materials After electronic searches on PubMed, Scopus, Cochrane Library, and Web of Science databases, initially 3367 papers were found, and 20 interventional studies were included in our analysis. We assessed the risk-difference between treatment and control (standard treatment) groups by pooling available data on ICU length of stay, number of ventilator free days, mortality, and changes in Sequential Organ Failure Assessment (SOFA) scores. Results The results of present studies revealed no significant effect of thiamine in combination with vitamin C, and HVT on number of free days of ventilation. Thiamine alone supplementation was associated with high mortality percentage (WMD: 5.17%; 95% CI: 2.67, 7.67). Thiamine in combination with vitamin C had no significant impact on mortality rate. In contrast, HVT could decrease mortality rate (WMD: − 7.23%; 95% CI: − 10.31, − 4.16; I-square: 0.0%). There was no significant effect of thiamine alone, co-administration of thiamine and vitamin C, and HVT on ICU length of stay. The results of the meta-analysis showed that thiamine alone and HVT supplementation had no significant effect on SOFA score. Interestingly, co-supplementation of thiamine and vitamin C had a significant decreasing effect on SOFA score (WMD: − 0.73; 95% CI: − 1.29, − 0.17; I-square: 0.0%). Conclusion In contrast to HVT, thiamine supplementation alone was associated with increased mortality rate in ICU. However, co-supplementation of thiamine and vitamin C had a significant decreasing effect on SOFA score. Thiamine, co-supplementation of thiamine and vitamin C and co-administration of hydrocortisone, vitamin C and thiamine (HVT) had no significant effect on free days of ventilation and ICU length of stay. HVT could decrease and thiamine supplementation could increase mortality rate in ICU. Co-supplementation of thiamine and vitamin C could decrease SOFA score.

Abstract
Objectives: Postoperative hyperlactatemia (POHL) is common in patients undergoing cardiac surgery and is associated with poor outcomes. The purpose of this study was to develop and validate two predictive models for POHL in patients undergoing elective cardiac surgery (ECS). Methods: We conducted a multicenter retrospective study enrolling 13,454 adult patients who underwent ECS. All patients involved in the analysis were randomly assigned to a training set and a validation set. Univariate and multivariate analyses were performed to identify risk factors for POHL in the training cohort. Based on these independent predictors, the nomograms were constructed to predict the probability of POHL and were validated in the validation cohort. Results: A total of 1,430 patients (10.6%) developed POHL after ECS. Age, preoperative left ventricular ejection fraction, renal insufficiency, cardiac surgery history, intraoperative red blood cell transfusion, and cardiopulmonary bypass time were independent predictors and were used to construct a full nomogram. The second nomogram was constructed comprising only the preoperative factors. Both models showed good predictive ability, calibration, and clinical utility. According to the predicted probabilities, four risk groups were defined as very low risk (<0.05), low risk (0.05–0.1), medium risk (0.1–0.3), and high risk groups (>0.3), corresponding to scores of ≤ 180 points, 181–202 points, 203–239 points, and >239 points on the full nomogram, respectively. Conclusions: We developed and validated two nomogram models to predict POHL in patients undergoing ECS. The nomograms may have clinical utility in risk estimation, risk stratification, and targeted interventions.

Thiamine increases resident endoglin positive cardiac progenitor cells and atrial contractile force in humans: A randomised controlled trial. Int J Cardiol 2021; 341:70-73. [PMID: 34461161 DOI: 10.1016/j.ijcard.2021.08.039] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2021] [Revised: 08/13/2021] [Accepted: 08/24/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND The heart has an intrinsic ability to regenerate, orchestrated by progenitor or stem cells. However, the relative complexity of non-resident cardiac progenitor cell (CPC) therapy makes modulation of resident CPCs a more attractive treatment target. Thiamine analogues improve resident CPC function in pre-clinical models. In this double blinded randomised controlled trial (identifier: ACTRN12614000755639), we examined whether thiamine would improve CPC function in humans. METHODS AND RESULTS High dose oral thiamine (one gram twice daily) or matching placebo was administered 3-5 days prior to coronary artery bypass surgery (CABG). Right atrial appendages were collected at the time of CABG, and CPCs isolated. There was no difference in the primary outcome (proliferation ability of CPCs) between treatment groups. Older age was not associated with decreased proliferation ability. In exploratory analyses, isolated CPCs in the thiamine group showed an increase in the proportion of CD34-/CD105+ (endoglin) cells, but no difference in CD34-/CD90+ or CD34+ cells. Thiamine increased maximum force developed by isolated trabeculae, with no difference in relaxation time or beta-adrenergic responsiveness. CONCLUSION Thiamine does not improve proliferation ability of CPC in patients undergoing CABG, but increases the proportion of CD34-/CD105+ cells. Having not met its primary endpoint, this study provides the impetus to re-examine CPC biology prior to any clinical outcome-based trial examining potential beneficial cardiovascular effects of thiamine.

Abstract
Background Thiamine is a precursor of the essential coenzyme thiamine pyrophosphate required for glucose metabolism; it improves the immune system function and has shown to reduce the risk of several diseases. The role of thiamine in critically ill septic patient has been addressed in multiple studies; however, it’s role in COVID-19 patients is still unclear. The aim of this study was to evaluate the use of thiamine as an adjunctive therapy on mortality in COVID-19 critically ill patients. Methods This is a two-center, non-interventional, retrospective cohort study for critically ill patients admitted to intensive care units (ICUs) with a confirmed diagnosis of COVID19. All patients aged 18 years or older admitted to ICUs between March 1, 2020, and December 31, 2020, with positive PCR COVID-19 were eligible for inclusion. We investigated thiamine use as an adjunctive therapy on the clinical outcomes in critically ill COVID-19 patients after propensity score matching. Results A total of 738 critically ill patients with COVID-19 who had been admitted to ICUs were included in the study. Among 166 patients matched using the propensity score method, 83 had received thiamine as adjunctive therapy. There was significant association between thiamine use with in-hospital mortality (OR = 0.39; 95% CI 0.19–0.78; P value = 0.008) as well as the 30-day mortality (OR = 0.37; 95% CI 0.18–0.78; P value = 0.009). Moreover, patients who received thiamine as an adjunctive therapy were less likely to have thrombosis during ICU stay [OR (95% CI) 0.19 (0.04–0.88), P value = 0.03]. Conclusion Thiamine use as adjunctive therapy may have potential survival benefits in critically ill patients with COVID-19. Additionally, it was associated with a lower incidence of thrombosis. Further interventional studies are required to confirm these findings. Supplementary Information The online version contains supplementary material available at 10.1186/s13054-021-03648-9.

Abstract
BACKGROUND Oxythiamine is a uremic toxin that acts as an antimetabolite to thiamine and has been associated with cases of Shoshin beriberi syndrome in adults. We sought to identify whether surgical stress and ischemia/reperfusion injury may precipitate functional thiamine deficiency in children peritransplant. METHODS We retrospectively analyzed a cohort of pediatric kidney transplant recipients. Oxythiamine levels were measured in pre-transplant serum samples by mass spectrometry and tested for association with severity of lactic acidosis in the first 24 h post-transplant. Secondary outcomes included association with hyperglycemia and indicators of dialysis adequacy (DA). RESULTS Forty-seven patients were included in the analysis. Median oxythiamine levels differed by modality, measuring 0.67 nM (IQR 0.31, 0.74), 0.34 nM (IQR 0.28, 0.56), and 0.25 nM (IQR 0.17, 0.38) for peritoneal dialysis (PD), hemodialysis (HD), and no dialysis, respectively (p = 0.05). Oxythiamine was associated with 24-h lactate levels (r = 0.38, p = 0.02) and negatively associated with DA (r = - 0.44, p = 0.02). Median oxythiamine levels were higher in patients with poor DA (0.92 nM (IQR 0.51, 1.01) vs. 0.40 nM (IQR 0.24, 0.51), p < 0.01). Sensitivity analysis showed absence of residual association of oxythiamine with 24-h lactate or dialysis modality, but remained significant for DA (p = 0.03). One patient manifested Shoshin beriberi syndrome (oxythiamine 2.03 nM). CONCLUSIONS Oxythiamine levels are associated with DA at transplant. Patients on PD with no residual kidney function and low DA manifest the highest oxythiamine levels and may be at an increased risk for developing acute Shoshin beriberi syndrome in the early post-transplant period.

Abstract
Thiamine (vitamin B1) is necessary for energy production, especially in the heart. Recent studies have demonstrated that thiamine supplementation for cardiac diseases is beneficial. However, the detailed mechanisms underlying thiamine-preserved cardiac function have not been elucidated. To this end, we conducted a functional analysis, metabolome analysis, and electron microscopic analysis to unveil the mechanisms of preserved cardiac function through supplementation with thiamine for ischemic cardiac disease. Male Sprague-Dawley rats (around 10 wk old) were used. Following pretreatment with or without thiamine pyrophosphate (TPP; 300 µM), hearts were exposed to ischemia (40 min of global ischemia followed by 60 min of reperfusion). We measured the left ventricle developed pressure (LVDP) throughout the protocol. The LVDP during reperfusion in the TPP-treated heart was significantly higher than that in the untreated heart. Metabolome analysis was performed using capillary electrophoresis-time-of-flight mass spectrometry, and it revealed that the TPP-treated heart retained higher adenosine triphosphate (ATP) levels compared with the untreated heart after ischemia. The metabolic pathway showed that there was a significant increase in fumaric acid and malic acid from the tricarboxylic acid cycle following ischemia. Electron microscope analysis revealed that the mitochondria size in the TPP-treated heart was larger than that in the untreated heart. Mitochondrial fission in the TPP-treated heart was also inhibited, which was confirmed by a decrease in the phosphorylation level of DRP1 (fission related protein). TPP treatment for cardiac ischemia preserved ATP levels probably as a result of maintaining larger mitochondria by inhibiting fission, thereby allowing the TPP-treated heart to preserve contractility performance during reperfusion.NEW & NOTEWORTHY We found that treatment with thiamine can have a protective effect on myocardial ischemia. Thiamine likely mediates mitochondrial fission through the inhibition of DRP1 phosphorylation and the preservation of larger-sized mitochondria and ATP concentration, leading to higher cardiac contractility performance during the subsequent reperfusion state.

Ezaka M, Tsukamoto J, Matsuo K, Kin N, Yamaoka K. Hyperlactatemia of dialysis-dependent patients after cardiac surgery impacts on in-hospital mortality: a two-center retrospective study. JA Clin Rep 2020; 6:47. [PMID: 32529341 PMCID: PMC7290016 DOI: 10.1186/s40981-020-00348-1] [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: 05/07/2020] [Accepted: 05/26/2020] [Indexed: 11/10/2022] Open
Abstract
Background Lactate is a well-known marker to estimate prognosis after cardiac surgery and critically ill patients. The liver and kidney have a major role in lactate metabolism; however, there was less characterized about the change of lactate and threshold to predict in-hospital mortality in dialysis-dependent patients undertaking cardiac surgery. We conducted this retrospective observational study to characterize when and how lactate values after cardiac surgery affected in-hospital mortality. Methods This two-center retrospective study included dialysis-dependent patients who underwent cardiac surgery with a cardiopulmonary bypass from January 2014 to December 2018. Lactate values were collected at three points: at ICU admission (T1), the maximum level of lactate within 24 h postoperatively (T2), and 24 h after ICU admission (T3). We determined hyperlactatemia as more than 2 mmol/L following previous studies. Results We enrolled 122 dialysis-dependent patients. The mean age was 73 ± 8 years and hyperlactatemia was observed in 100 patients (81.9%). In-hospital mortality was 11.4%. Univariate analysis and area under curve in ROC suggested that T2 lactate was the most significantly associated with in-hospital mortality (AUC = 0.845). Multivariate logistic analysis showed a significant association between in-hospital mortality when patients showed early peak lactate levels of > 4.5 mmol/L after ICU admission (adjusted OR 8.35; 95% CI: 1.44–57.13). Conclusions In dialysis-dependent patients after cardiac surgery, the early-onset of a maximum arterial lactate concentration of > 4.5 mmol/L was significantly associated with in-hospital mortality.

Abstract
OBJECTIVE To test the feasibility and investigate possible cardiovascular effects of a sustained high-dose intravenous thiamine protocol in patients undergoing combined valvular and coronary artery bypass graft surgery. DESIGN Randomized, placebo-controlled, pilot feasibility trial. SETTING Cardiac surgery department of a tertiary hospital. PARTICIPANTS Forty patients undergoing combined valvular and coronary artery bypass surgery. INTERVENTIONS Intravenous thiamine (600 mg on the day of surgery, and 400 mg/day on postoperative days 1, 2, and 3) or placebo. MEASUREMENTS AND MAIN RESULTS The primary feasibility endpoints were recruitment rate and protocol compliance. Secondary endpoints included markers of possible biological and physiological effects. The mean recruitment rate was 8 patients per month and protocol compliance was 97.5%. There were no differences in median peak postoperative lactate (2.7 mmol/L [interquartile range [IQR] 1.4-4.6] for thiamine v 2.5 mmol/L [IQR 1.4-3.6] for placebo; p = 0.53), median peak postoperative creatinine (104 µmol/L [IQR 92.5-129] for thiamine v 99 µmol/L [IQR 86.5-109.5] for placebo; p = 0.53), median nadir postoperative cardiac index (1.8 L/min/m2 [IQR 1.5-2.1] for thiamine v 2.2 L/min/m2 [IQR 1.5-2.5] for placebo; p = 0.25), or the number of patients on vasopressor/inotropic agents (thiamine, 12 [63%]; placebo, 12 [60%]; p = 0.80), or in the total inotrope/vasopressor dose 0.14 µg/kg for thiamine v 0.12 µg/kg for placebo; p = 0.88). CONCLUSIONS A double-blind trial of sustained high-dose intravenous thiamine supplementation in higher-risk cardiac surgery patients was feasible and appeared to be safe. However, such treatment did not demonstrate evidence of biological or physiological effects.

Abstract
Persistent physical impairment is frequently encountered after critical illness. Recent data point towards mitochondrial dysfunction as an important determinant of this phenomenon. This narrative review provides a comprehensive overview of the present knowledge of mitochondrial function during and after critical illness and the role and potential therapeutic applications of specific micronutrients to restore mitochondrial function. Increased lactate levels and decreased mitochondrial ATP-production are common findings during critical illness and considered to be associated with decreased activity of muscle mitochondrial complexes in the electron transfer system. Adequate nutrient levels are essential for mitochondrial function as several specific micronutrients play crucial roles in energy metabolism and ATP-production. We have addressed the role of B vitamins, ascorbic acid, α-tocopherol, selenium, zinc, coenzyme Q10, caffeine, melatonin, carnitine, nitrate, lipoic acid and taurine in mitochondrial function. B vitamins and lipoic acid are essential in the tricarboxylic acid cycle, while selenium, α-tocopherol, Coenzyme Q10, caffeine, and melatonin are suggested to boost the electron transfer system function. Carnitine is essential for fatty acid beta-oxidation. Selenium is involved in mitochondrial biogenesis. Notwithstanding the documented importance of several nutritional components for optimal mitochondrial function, at present, there are no studies providing directions for optimal requirements during or after critical illness although deficiencies of these specific micronutrients involved in mitochondrial metabolism are common. Considering the interplay between these specific micronutrients, future research should pay more attention to their combined supply to provide guidance for use in clinical practise.

Abstract
Nutrition support is increasingly recognized as a clinically relevant aspect of the intensive care treatment of cardiac surgery patients. However, evidence from adequate large-scale studies evaluating its clinical significance for patients’ mid- to long-term outcome remains sparse. Considering nutrition support as a key component in the perioperative treatment of these critically ill patients led us to review and discuss our understanding of the metabolic response to the inflammatory burst induced by cardiac surgery. In addition, we discuss how to identify patients who may benefit from nutrition therapy, when to start nutritional interventions, present evidence about the use of enteral and parenteral nutrition and the potential role of pharmaconutrition in cardiac surgery patients. Although the clinical setting of cardiac surgery provides advantages due to its scheduled insult and predictable inflammatory response, researchers and clinicians face lack of evidence and several limitations in the clinical routine, which are critically considered and discussed in this paper.

Abstract
BACKGROUND Thiamine has a crucial role in energy production, and consequently thiamine deficiency (TD) has been associated with cardiac failure, neurological disorders, oxidative stress (lactic acidosis and sepsis) and refeeding syndrome (RFS). This review aims to explore analytical methodologies of thiamine compound quantification and highlight similarities, variances and limitations of current techniques and how they may be relevant to patients. CONTENT An electronic search of Medline, PubMed and Embase databases for original articles published in peer-reviewed journals was conducted. MethodsNow was used to search for published analytical methods of thiamine compounds. Keywords for all databases included "thiamine and its phosphate esters", "thiamine methodology" and terms related to critical illness. Enquiries were also made to six external quality assurance (EQA) programme organisations for the inclusion of thiamine measurement. SUMMARY A total of 777 published articles were identified; 122 were included in this review. The most common published method is HPLC with florescence detection. Two of the six EQA organisations include a thiamine measurement programme, both measuring only whole-blood thiamine pyrophosphate (TPP). No standard measurement procedure for thiamine compound quantification was identified. OUTLOOK Overall, there is an absence of standardisation in measurement methodologies for thiamine in clinical care. Consequently, multiple variations in method practises are prohibiting the comparison of study results as they are not traceable to any higher order reference. Traceability of certified reference materials and reference measurement procedures is needed to provide an anchor to create the link between studies and help bring consensus on the clinical importance of thiamine.

Abstract
Elevated lactate is a common occurrence after cardiac surgery. This review summarizes the literature on the complex etiology of lactate elevation during and after cardiac surgery, including considerations of oxygen delivery, oxygen utilization, increased metabolism, lactate clearance, medications and fluids, and postoperative complications. Second, the association between lactate and a variety of outcomes are described, and the prognostic role of lactate is critically assessed. Despite the fact that elevated lactate is strongly associated with many important outcomes, including postoperative complications, length of stay, and mortality, little is known about the optimal management of postoperative patients with lactate elevations. This review ends with an assessment of the limited literature on this subject.

Abstract
Background Thiamine is a vitamin that is essential for adequate aerobic metabolism. The objective of this study was to determine if thiamine administration prior to coronary artery bypass grafting would decrease post-operative lactate levels as a measure of increased aerobic metabolism. Methods We performed a randomized, double-blind, placebo-controlled trial of patients undergoing coronary artery bypass grafting. Patients were randomized to receive either intravenous thiamine (200 mg) or placebo both immediately before and again after the surgery. Our primary endpoint was post-operative lactate levels. Additional endpoints included pyruvate dehydrogenase activity, global and cellular oxygen consumption, post-operative complications, and hospital and intensive care unit length of stay. Results Sixty-four patients were included. Thiamine levels were significantly higher in the thiamine group as compared to the placebo group immediately after surgery (1200 [683, 1200] nmol/L vs. 9 [8, 13] nmol/L, p < 0.001). There was no difference between the groups in the primary endpoint of lactate levels immediately after the surgery (2.0 [1.5, 2.6] mmol/L vs. 2.0 [1.7, 2.4], p = 0.75). Relative pyruvate dehydrogenase activity was lower immediately after the surgery in the thiamine group as compared to the placebo group (15 % [11, 37] vs. 28 % [15, 84], p = 0.02). Patients receiving thiamine had higher post-operative global oxygen consumption 1 hour after the surgery (difference: 0.37 mL/min/kg [95 % CI: 0.03, 0.71], p = 0.03) as well as cellular oxygen consumption. We found no differences in clinical outcomes. Conclusions There were no differences in post-operative lactate levels or clinical outcomes between patients receiving thiamine or placebo. Post-operative oxygen consumption was significantly increased among patients receiving thiamine.

Abstract
In 2015, the demand for the presence of cardiothoracic anesthesiologists outside of the cardiac operating rooms continues to expand. Most notably, cardiothoracic anesthesiologists now find themselves called on to care for patients postoperatively in the cardiothoracic surgical intensive care unit. This article is the first in this annual series to review relevant contributions in postoperative cardiac critical care that may influence the cardiac anesthesiologist. We explore the use of extracorporeal membrane oxygenation, management of postoperative atrial fibrillation and coagulopathy, metabolic support of the critically ill cardiothoracic surgical patient, and new insights into delirium and acute kidney injury.
