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.

AbstractBackground: Unexpected death within 24 hours of admission is a real challenge for the clinician in the emergency room. How to diagnose these patients and the right approach to prevent sudden death with 24 hours is still an enigma. The aims of our study were to find the independent factors that may affect the clinical outcome in the first 24 hours of admission to the hospital.Methods: We performed a retrospective study defining unexpected death within 24 hours of admission in our Department of Medicine in the last 6 years. We found 43 patients who died within 24 hours of admission, and compared their clinical and biochemical characteristics to 6055 consecutive patients who were admitted in that period of time and did not die within the first 24 hours of admission. The parameters that were used include gender, age, temperature, clinical and laboratory criteria for SIRS, arterial blood lactate, and arterial blood pH.Results: Most of the patients who died within 24 hours had sepsis with SIRS. These patients were older (78.6±14.7 vs. 65.2±20.2 years [p<.0001]), had higher lactate levels (8.0±4.8 vs. 2.1±1.8mmol/L[p<.0001]), and lower pH (7.2±0.2 vs. 7.4±0.1 [p<.0001]). Logistic regression analysis found that lactate was the strongest independent parameter to predict death within 24 hours of admission (OR1.366 [95% CI 1.235-1.512]), followed by old age (OR 1.048 [95% CI 1.048-1.075] and low arterial blood pH (OR 0.007 [CI <0.001-0.147]). When gender was analyzed, pH was not an independent variable in females (only in males).Conclusions: The significant independent variable that predicted death within 24 hours of admission was arterial blood lactate level on admission. Older age was also an independent variable; low pH affected only males, but was a less dominant variable. We suggest use of arterial blood lactate level on admission as a bio-marker in patients with suspected sepsis admitted to the hospital for risk assessment and prediction of death within 24 hours of admission.

Lactate has been thoroughly studied and found useful for stratification of patients with sepsis, in the Intensive Care Unit, and trauma care. However, little is known about lactate as a risk-stratification marker in the Medical Emergency Team- (MET-) call setting. We aimed to determine whether the arterial blood lactate level at the time of a MET-call is associated with increased 30-day mortality. This is an observational study on a prospectively gathered cohort at a regional secondary referral hospital. All MET-calls during the two-year study period were eligible. Beside blood lactate, age and vital signs were registered at the call. Among the 211 calls included, there were 64 deaths (30.3%). Median lactate concentration at the time of the MET-call was 1.82 mmol/L (IQR 1.16–2.7). We found differences between survivors and nonsurvivors for lactate and oxygen saturation, a trend for age, but no significant correlations between mortality and systolic blood pressure, respiratory rate, and heart rate. As compared to normal lactate (<2.44 mmol/L), OR for 30-day mortality was 3.54 (p<0.0006) for lactate 2.44–5.0 mmol/L and 4.45 (p<0.0016) for lactate > 5.0 mmol/L. The present results support that immediate measurement of blood lactate in MET call patients is a useful tool in the judgment of illness severity.

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.
