The Difference

Background Dengue shock syndrome (DSS) mortality is still high.Monitoring of blood lactate level is important to evaluate shock.Objectives The study were to review the difference between bloodlactate level of DSS and that of dengue hemorrhagic fever (DHF),to correlate blood lactate level with hypoxia state as shock riskfactors (PaO 2 , oxygen saturation, and anion gap) and to determinethe cut-off point of blood lactate level to predict shock.Methods The study was carried out at the Department of ChildHealth, Medical School, University of Indonesia, CiptoMangunkusumo Hospital, Jakarta, from January until July 2006.Three mL venous blood specimen was collected from all subjectsfor peripheral blood, blood gasses, serology, and blood lactateexaminations. This study consisted of a retrospective cohort anda cross sectional method. Data were analyzed with Chi-squaretest. Continous data tested using Mann-Whitney method. Toknow the correlation between blood lactate level and shock riskfactors we use logistic regression test.Results In DSS group, 73% shows hyperlactatemia (lactate =2mmol/L). Conversion of lactate means between two groups issignificantly different from day one to day two and three. Therewas a negative correlation between lactate level and pO 2 andoxygen saturation. Oxygen saturation is the only value that hasclinical correlation. Regressions analysis can be applied using Y= 7.05–0.05 X equation. The cut-off point of lactate level asmarker for shock by using ROC curve is 32.015 mmol/L with 70%sensitivity and 83.3% specificity.Conclusions Hyperlactatemia in DSS can be considered as a signfor unappropriate treatment of shock. Blood lactate level can beused as a biochemical marker for tissue hypoxia, to assess severityof the disease, as monitoring of treatment, and has prognosticvalue of DHF cases.

Introduction: Sepsis and its consequences, severe sepsis and septic shock is at menace in country like ours where infectious disease are at toll. Early diagnosis and treatment is very important to decrease the morbidity and mortality. Shock index is one of such tool that is very handy in these situations as this is just a mathematical calculation using heart rate(HR) and systolic blood pressure(SBP). The main aim of this study was to find the effectiveness of using SI as an adjunct to blood lactate in diagnosing patients in sepsis. Methods: This was an observational hospital-based study conducted at Emergency Department of TUTH, Maharajgunj on 104 patients, obtained by purposive sampling method, who had presented to the “Red Area”, aged between 18 to 65 years. These patients were screened for severe sepsis using triage vital signs, basic laboratory tests and an initial serum lactate level. Test characteristics were calculated for hyperlactatemia. I considered the following covariates in our analysis: heart rate >90 beats/min; mean arterial pressure <65 mmHg; respiratory rate > 20 breaths/min; ≥2 SIRS including white blood cell count; SI <0.6; SI 0.6 to 1; SI 1 to 1.4and SI ≥ 1.4.  Results: There was a positive correlation between shock index and blood lactate level, r=0.2, n=104, p=0.042. No relationship was found between SI>=1 and hyperlactemia, X2 (.285, N = 104) = 1, p =.594 and relationship was found between SI >=0.7 and hyperlactemia, X2 (4.1, N = 104) = 1, p =.04. sensitivity and specificity for detecting hyperlactemia of SI>=1, SI.=0.7, SIRS was 84% and 20%, 93% and 0%, 79% and 20% respectively. Conclusions: There was weak correlation between the lactate level and shock index with statistically significant correlation between the shock index grouped >=0.7 and hyperlactatemia with high sensitivity and very low specificity.

Background: We developed a new device for quantifying capillary refill time (CRT) by applying the pulse oximeter principle, and reported the excellent correlation between quantitative CRT (Q-CRT) and tissue hypoperfusion status as represented by arterial blood lactate levels in critically ill patients in the pilot study. Methods: Diagnostic accuracy study was undergone in ICU of a tertiary emergency medical center. While the pulse oxygen saturation sensor was placed on the finger of the patients, transmitted light intensity was measured with a pulse oximeter (OLV-3100, Nihon Kohden Corp., Japan) before start and during compression of the finger. Correlation between delta Ab, defined as the absorbance of light intensity of infra-red (A-ir) minus that of red (A-r), and arterial blood lactate level was analyzed. Results: The delta Ab was analyzed a total of 69 waveforms in 23 patients. The sensitivity, specificity, positive predictive value, and negative predictive value of the delta Ab less than 0.06 for predicting a lactate level more than 2.0 mmol/l were 100%, 93%, 89%, 100%, respectively. Conclusions: The delta Ab was well correlated to high level of blood lactate level in critically ill patients. Further study will confirm to place the delta Ab as one of non-invasive predictors of tissue perfusion status.

We examined the hypothesis that high blood lactate level in ICU patient after adult cardiac surgery under cardiopulmonary bypass is associated with early adverse outcome. The objective of this study was to evaluate whether blood lactate level after cardiac surgery is predictor of the early outcome after adult cardiac surgery under CPB. In this prospective observational study total 100 patients were enrolled who underwent elective cardiac surgery under CPB as per inclusion and exclusion criteria. Blood lactate levels > 3mmol/ L 6 hours after ICU transfer were present in 57(57%) patients. The binary logistic regression analysis showed that blood lactate level 6 hours after ICU transfer is an independent predictor for prolonged mechanical ventilation time (OR 2.417, 95% CI 1.272 - 4.596, p = .007), prolonged ICU stay (OR 1.562, 95% CI 1.181 - 2.067, p = .002), neurological deficit (OR 2.432, 95% CI 1.539 - 3.843, p = .001), pulmonary complication (OR 1.301, 95% CI 1.011 - 1.676, p = .041), arrhythmia (OR 1.444, 95% CI 1.102 - 1.893, p = .008), renal dysfunction (OR 1.838, 95% CI 1.352 - 2.497, p = .001) and mortality (OR 1.822, 95% CI 1.123- 2.955, p = .015). In conclusion, blood lactate level 6 hours after ICU transfer is an independent risk factor for worse outcomes in adult patients including mortality after cardiac surgery under CPB.University Heart Journal Vol. 13, No. 2, July 2017; 50-54
