Prehospital lactate improves prediction of the need for immediate interventions for hemorrhage after trauma

Abstract The blood lactate level is used to guide the management of trauma patients with circulatory disturbance. We hypothesized that blood lactate levels at the scene (Lac scene) could improve the prediction for immediate interventions for hemorrhage. We prospectively measured blood lactate levels and assessed retrospectively in 435 trauma patients both at the scene and on arrival at the emergency room (ER) of a level I trauma center. Primary outcome was immediate intervention for hemorrhage defined as surgical/radiological intervention and/or blood transfusion within 24 h. Physiological variables plus Lac scene significantly increased the predictive value for immediate intervention (area under the curve [AUC] 0.882, 95% confidence interval [CI] 0.839–0.925) compared to that using physiological variables only (AUC 0.837, 95% CI 0.787–0.887, P = 0.0073), replicated in the validation cohort (n = 85). There was no significant improvement in predicting value of physiological variables plus Lac scene for massive transfusion compared to physiological variables (AUC 0.903 vs 0.895, P = 0.32). The increased blood lactate level per minute from scene to ER was associated with increased probability for immediate intervention (P < 0.0001). Both adding Lac scene to physiological variables and the temporal elevation of blood lactate levels from scene to ER could improve the prediction of the immediate intervention.

Blood Lactate Levels

Metabolic acidosis in severe malaria usually occurs in the form of lactic acidosis. The present study aimed to collate articles from the literature that have reported blood lactate levels in patients with severe malaria and tested the hypothesis that blood lactate levels are elevated in patients with malaria compared to those with uncomplicated malaria. Moreover, the difference in lactate levels between patients who died and those who survived was estimated using a meta-analytic approach. Potentially relevant studies were searched for in PubMed, Web of Science, and Scopus. The quality of the included studies was assessed using the Jadad scale and strengthening the reporting of observational studies in epidemiology (STROBE). The pooled mean blood lactate in patients with severe malaria, the pooled weighted mean difference (WMD) of blood lactate between patients with severe malaria and those with uncomplicated malaria, and the pooled WMD and 95% CI of blood lactate between patients who died from and those who survived severe malaria were estimated using the random-effects model. Heterogeneity among the outcomes of the included studies was assessed using Cochran’s Q and I2 statistics. A meta-regression analysis was performed to identify the source(s) of heterogeneity of outcomes among the included studies. A subgroup analysis was further performed to separately analyze the outcomes stratified by the probable source(s) of heterogeneity. Publication bias was assessed by the visual inspection of the funnel plot asymmetry. Of 793 studies retrieved from the searches, 30 studies were included in qualitative and quantitative syntheses. The pooled mean lactate in patients with severe malaria was 5.04 mM (95% CI: 4.44–5.64; I2: 99.9%; n = 30,202 cases from 30 studies). The mean lactate in patients with severe malaria (1568 cases) was higher than in those with uncomplicated malaria (1693 cases) (p = 0.003; MD: 2.46; 95% CI: 0.85–4.07; I2: 100%; nine studies). The mean lactate in patients with severe malaria who died (272 cases) was higher than in those with severe malaria who survived (1370 cases) (p < 0.001; MD: 2.74; 95% CI: 1.74–3.75; I2: 95.8%; six studies). In conclusion, the present study showed a high mean difference in blood lactate level between patients with severe malaria and patients with uncomplicated malaria. In addition, there was a high mean difference in blood lactate level between patients with severe malaria who died compared to those with severe malaria who survived. Further studies are needed to investigate the prognostic value of blood lactate levels to identify patients who are at high risk of developing severe malaria or dying.

Blood Lactate Levels

Background: Assessment of disease severity in patients with septic shock (SS) is crucial in determining optimal level of care. In both pre- and in-hospital settings, the clinical picture alone is not sufficient for assessing disease severity and outcomes. Because blood lactate level is included in the clinical criteria of SS it should be considered to improve the assessment of its severity. This study aims to investigate the relationship between pre-hospital blood lactate level and 30-day mortality in patients with SS. Methods: From 15 April 2017 to 15 April 2019, patients with SS requiring pre-hospital Mobile Intensive Care Unit intervention (MICU) were prospectively included in the LAPHSUS study, an observational, non-randomized controlled study. Pre-hospital blood lactate levels were measured at the time of first contact between the patients and the MICU. Results: Among the 183 patients with septic shock requiring action by the MICU drawn at random from LAPHSUS study patients, six (3%) were lost to follow-up on the 30th day and thus 177 (97%) were analyzed for blood lactate levels (mean age 70 ± 14 years). Pulmonary, urinary and digestive infections were probably the cause of the SS in respectively 58%, 21% and 11% of the cases. The 30-day overall mortality was 32%. Mean pre-hospital lactatemia was significantly different between patients who died and those who survived (respectively 7.1 ± 4.0 mmol/L vs. 5.9 ± 3.5 mmol/L, p < 10−3). Using Cox regression analysis adjusted for potential confounders we showed that a pre-hospital blood lactate level ≥ 4 mmol/L significantly predicted 30-day mortality in patients with SS (adjusted hazard ratio = 2.37, 95%CI (1.01–5.57), p = 0.04). Conclusion: In this study, we showed that pre-hospital lactatemia predicts 30-day mortality in patients with septic shock handled by the MICU. Further studies will be needed to evaluate if pre-hospital lactatemia alone or combined with clinical scores could affect the triage decision-making process for those patients.

Background: A high perioperative blood lactate level has been reported to be associated with poor outcomes after cardiac surgery. More than isolated peaks of lactate values, it should be more interesting to take into account changes in intraoperative blood lactate level (∆Lact). This large-scale retrospective study evaluated the relationship between ∆Lact and overall intensive care unit morbidity and 30-day all-cause mortality. Methods: Perioperative data from consecutive patients undergoing on-pump cardiac surgery between September 2010 and June 2016 were retrospectively analysed through our institutional database including clinical, transfusion and laboratory test results implemented prospectively by physicians. Blood lactate levels were initially measured after induction of anaesthesia (baseline) and periodically during the surgery. The ∆Lact was defined as the difference between the highest intraoperative blood lactate and the baseline lactate level and offered the opportunity to stratify patients into four subgroups: ⩽0, 0.1-0.9, 1-1.9 and ⩾2 mmol L−1. Results: From the 7,795 patients found eligible during the study period, 7,447 patients were analysed. The median ∆Lact of our patients was 0.6 (0.3-1) mmol L−1. Most of the studied patients (65.9%) exhibited a ∆Lact between 0.1 and 0.9 mmol L−1. A concentration-dependent relationship was observed between ∆Lact and intensive care unit morbidity and 30-day mortality. After adjustment for co-variables, all ∆Lact > 0 was associated with an increase in overall intensive care unit morbidity. An independent relationship was also found between ∆Lact and 30-day mortality as of a 1 mmol L−1 increase. Conclusion: Our results suggest that ∆Lact is associated with poor short-term outcomes in adult cardiac surgical patients.

Abstract Background Hyperlactatemia is associated with a poor prognosis in cardiac surgery patients. This study explored the impact of target blood pressure management during cardiopulmonary bypass (CPB) on blood lactate levels after cardiac surgery. Methods Adult patients undergoing cardiac valve surgery between 20/1/2020 and 30/6/2020 at Shanghai Chest Hospital were enrolled. The patients were randomized into a low mean arterial pressure (L-MAP) group (target MAP between 50 and 60 mmHg) or a high mean arterial pressure (H-MAP) group (target MAP between 70 and 80 mmHg), n = 20 for each. Norepinephrine was titrated only during CPB to maintain MAP at the target level. Blood lactate levels in the two groups were detected before the operation (T0), at the end of CPB (T1), at the end of the operation (T2), 1 h after the operation (T3), 6 h after the operation (T4) and 24 h after the operation (T5). The primary outcome was the blood lactate level at the end of the operation (T2). The secondary outcomes included the blood lactate level at T1, T3, T4, and T5 and the dose of epinephrine and dopamine within 24 h after the operation, time to extubation, length of stay in the ICU, incidence of readmission within 30 days, and mortality within 1 year. Results Forty patents were enrolled and analyzed in the study. The lactate level in the H-MAP group was significantly lower than that in the L-MAP group at the end of the operation (3.1 [IQR 2.1, 5.0] vs. 2.1 [IQR 1.7, 2.9], P = 0.008) and at the end of CPB and 1 hour after surgery. The dose of epinephrine within 24 h after the operation, time to extubation and length of stay in the ICU in the L-MAP group were significantly higher than those in the H-MAP group. Conclusions Maintaining a relatively higher MAP during CPB deceased the blood lactate level at the end of surgery, reduced epinephrine consumption, and shortened the time to extubation and length of stay in the ICU after surgery. Trial registration This single-center, prospective, RCT has completed the registration of the Chinese Clinical Trial Center at 8/1/2020 with the registration number ChiCTR2000028941. It was conducted from 20/1/2020 to 30/6/2020 as a single, blinded trial in Shanghai Chest Hospital.

PURPOSE: To evaluate the accuracy of different parameters in predicting early (one-month) mortality of patients submitted to orthotopic liver transplantation (OLT). METHODS: This is a retrospective study of forty-four patients (38 males and 10 females, mean age of 52.2 ± 8.9 years) admitted to the Intensive Care Unit of a tertiary hospital. Serial lactate blood levels, APACHE II, MELD post-OLT, creatinine, bilirubin and INR parameters were analyzed by receiver-operator characteristic (ROC) curves as evidenced by the area under the curve (AUC). The level of significance was set at 0.05. RESULTS: The mortality of OLT patients within one month was 17.3%. Differences in blood lactate levels became statistically significant between survivors and nonsurvivors at the end of the surgery (p<0.05). The AUC was 0.726 (95%CI = 0.593-0.835) for APACHE II (p = 0.02); 0.770 (95%CI = 0.596-0.849) for blood lactate levels (L7-L8) (p = 0.03); 0.814 (95%CI = 0.690-0.904) for MELD post-OLT (p < 0.01); 0.550 (95%CI = 0.414-0.651) for creatinine (p = 0.64); 0.705 (95%CI = 0.571-0.818) for bilirubin (p = 0.05) and 0.774 (95%CI = 0.654-0.873) for INR (p = 0.02). CONCLUSION: Among the studied parameters, MELD post-OLT was more effective in predicting early mortality after OLT.

The Impact

Latar Belakang: Karsinoma nasofaring (KNF) merupakan keganasan tersering pada kepala dan leher. Pilihan terapi KNF adalah radioterapi dan kemoterapi yang berhubungan dengan toksisitas, resistensi obat, dan rekurensi. Intervensi metabolik yang didasarkan pada perubahan metabolisme sel kanker merupakan salah satu strategi terapi kanker pada saat ini. Untuk dapat mengetahuinya perlu dipahami pengaruh ekspresi p53 dan hypoxia-inducible factor 1 (HIF1) terhadap peningkatan kadar laktat jaringan nasofaring pada pasien KNF. Tujuan: Mengetahui pengaruh ekspresi p53 dan HIF1 terhadap peningkatan kadar laktat jaringan nasofaring, dan untuk mengetahui kesesuaian antara kadar laktat darah dengan laktat jaringan nasofaring. Metode: Penelitian cross sectional melibatkan 10 subjek, dilakukan biopsi nasofaring dengan tuntunan nasoendoskopi untuk pemeriksaan histopatologi, ekspresi p53 dan HIF1 dengan imunohistokimia, laktat jaringan nasofaring dengan colorimetric, dan laktat darah. Hasil: Seluruh subjek mengalami peningkatan ekspresi p53 dan HIF1 dengan rerata p53 19,53±7,37 dan HIF1 24,30±12,28. Seluruh subjek penelitian memiliki kadar laktat jaringan meningkat, dengan rerata kadar laktat 0,67±0,39. Kadar laktat darah subjek cenderung meningkat dengan rerata 2,93±0,65. Terdapat pengaruh peningkatan ekspresi p53 terhadap peningkatan kadar laktat jaringan (p=0,002). Terdapat pengaruh peningkatan ekspresi HIF1 terhadap peningkatan kadar laktat jaringan (p=0,042). Tidak terdapat kesesuaian antara kadar laktat darah dengan laktat jaringan nasofaring (p=0,000). Kesimpulan: Peningkatan ekspresi p53 dan HIF1 berpengaruh terhadap peningkatan kadar laktat jaringan nasofaring pada pasien KNF, namun kadar laktat darah tidak menggambarkan kadar laktat jaringan nasofaring. ABSTRACTBackground: Nasopharyngeal carcinoma (NPC) is the most frequent malignancy of the head and neck. The options of NPC therapy are radiotherapy and chemotherapy, associated with toxicity, drug resistance, and recurrence. Metabolic intervention based on changes in cancer cell metabolism is currently one of the strategies of cancer therapy. Aim: To determine the impact of p53 and hypoxia-inducible factor 1 (HIF1) expression on elevated lactate levels of nasopharyngeal tissue, and to determine the compatibility between blood lactate and nasopharyngeal tissue lactate levels in patients with NPC. Method: This cross-sectional study involved 10 subjects who underwent nasopharyngeal biopsy for histopathologic examination, p53 and HIF1 expression using immunohistochemistry, lactate of nasopharyngeal tissue using colorimetric, and blood lactate. Results: All subjects had increased expression of p53 and HIF1 with p53 mean of 19.53±7.37 and HIF1 mean of 24.30±12.28. All subjects had elevated tissue lactate levels, with lactate levels mean of 0.67±0.39. The blood lactate level of the subjects increased, with blood lactate level mean of 2.93±0.65. There was a significant increasing impact of p53 expression on tissue lactate elevated level (p=0.002) and a significant increasing impact of HIF1 expression on tissue lactate elevated level (p=0.042). There was no correlation between lactate levels of blood lactate and nasopharyngeal tissue (p=0.000). Conclusion: Increased expression of p53 and HIF1 had an effect on increased levels of lactate nasopharyngeal tissue in NPC patients, but blood lactate levels did not have a correlation with lactate levels of nasopharyngeal tissue.

Background: The search for the best marker or set of markers for the diagnosis, prognosis and treatment of ‘at risk’ trauma patients is ongoing. Serial estimation of serum lactate values are thought to help predict morbidity and mortality in trauma victims. There is evidence to support the use of blood lactate levels as an end point of resuscitation. The presence of elevated lactic acid levels in the serum can direct the treating physician to safe and correct timing of any surgical intervention. Early identification and aggressive resuscitation measures aimed at correcting the impaired metabolic dysfunction improves survival and reduces complications in severely injured trauma patients. Methods: A prospective analytical study of 52 patients with polytrauma and multiple trauma admitted within 12 hours of injury to our institution between March 2007 to February 2008 was carried out. All the patients were resuscitated as per the advance trauma life support (ATLS) protocol in the emergency room. Serum lactate level was analyzed on the 1st, 5th and 14th day of injury. Serum lactate levels greater than 2 milimoles/L was considered abnormal and serum lactate level greater than 5 milimoles/L was considered significant. Results: There were 45 males and 7 females with an average age of 32.8 years (18-82). 18 patients out of 52 sustained polytrauma. Of these 18 patients, 8 patients sustained chest injury, 4 had head injury and 2 had abdominal injury. In the polytrauma group (n-18), 5 patients had an elevated lactate above 2 milimoles/Lon admission. 2 patients who had significant rise of lactate (>5 milimoles/L) on admission died on the 5th day. Out of 34 multiple trauma patients, 13 patients had an elevated lactate level at admission. One patient in this group with lactate level 7.2 died of ARDS on 3rd day of admission. Conclusion: Blood lactate appears to be a reliable marker reflecting not only the severity of the shock, but also for predicting survival. The longer the lactate is elevated, the more a patient is likely to develop multiple organ dysfunctions and die. Lactate levels followed over time is more reliable than isolated values.

Background Lactate has been shown to be a prognostic biomarker in trauma. Although lactate clearance has already been proposed as an intermediate endpoint in randomized trials, its precise role in trauma patients remains to be determined. Methods Blood lactate levels and lactate clearance (LC) were calculated at admission and 2 and 4 h later in trauma patients. The association of initial blood lactate level and lactate clearance with mortality was tested using receiver-operating characteristics curve, logistic regression using triage scores, Trauma Related Injury Severity Score as a reference standard, and reclassification method. Results The authors evaluated 586 trauma patients (mean age 38±16 yr, 84% blunt and 16% penetrating, mortality 13%). Blood lactate levels at admission were elevated in 327 (56%) patients. The lactate clearance should be calculated within the first 2 h after admission as LC0-2 h was correlated with LC0-4 h (R=0.55, P<0.001) but not with LC2-4 h (R=0.04, not significant). The lactate clearance provides additional predictive information to initial blood lactate levels and triage scores and the reference score. This additional information may be summarized using a categorical approach (i.e., less than or equal to -20 %/h) in contrast to initial blood lactate. The results were comparable in patients with high (5 mM/l or more) initial blood lactate. Conclusions Early (0-2 h) lactate clearance is an important and independent prognostic variable that should probably be incorporated in future decision schemes for the resuscitation of trauma patients.

ABSTRACT Introduction: Physical exercise at high altitude has become constant. However, the risks associated with this type of exercise represent a major concern, considering the influence of important stressors such as hypoxia and physical exercise on psychobiological and physiological responses. Objective: Analyze the mood state and behavior of physiological variables of volunteers subjected to a progressive loading protocol until they reached maximum volitional exhaustion, both at sea level and at a simulated altitude of 4500 meters. Method: For both conditions studied, the volunteers responded to two instruments that assess mood responses: The Brunel Mood Scale and the Visual Analogue Mood Scale. They also underwent blood sampling to measure blood lactate levels and to evaluate oxygen-hemoglobin saturation. These procedures were performed before, immediately after, and 30 and 60 minutes after the end of the protocol. Results: Hypoxia triggered negative effects on mood responses, especially when compared to sea level conditions. An increase in fatigue level (p=0.02) and mental confusion (p=0.04) was observed immediately after the exercise session, and reduction of vigor (p=0.03) was noted at 30 minutes, accompanied by a reduction in oxygen-hemoglobin saturation immediately after the session and at 30 minutes. There was also an increase in blood lactate levels immediately after the session (p=0.006). Conclusion: The particularities of the hypoxic environment associated with maximum exercise are able to cause a deterioration of mood and physiological responses, which can negatively modulate physical performance. This is a cross-sectional clinical study.
