Non-invasive haemoglobin measurement in patients undergoing elective Caesarean section
British Journal of Anaesthesia, 2012
Editor's key points † This study evaluated a new non-invasive co-oximeter in patients undergoing Caesarean section (CS) under regional anaesthesia. † There were variable bias and wide limits of agreement between co-oximeter and laboratory haemoglobin (Hb) values. † Haemoglobin from Pulse CO-Oximeter measurements tended to be higher than laboratory Hb values with the greatest differences at 24 h after CS.

Background: Haemoglobin measurement in antenatal care can help in timely detection and treatment of anaemia, which is a major contributory factor to maternal mortality in developing countries. The transport of samples for haemoglobin assessment may delay the treatment, resulting in preventable deaths. Haemoglobin measurement by point of care testing (POCT) devices is easy, quick and less invasive. There are very few studies which compare the capillary blood haemoglobin using point of care devices with venous blood samples. This study was conducted to compare capillary blood haemoglobin using POCT device with venous blood haemoglobin using haematology analysers in antenatal Indian females.Methods: One hundred pregnant women were recruited during their first trimester antenatal visits. Hemoglobin by finger prick capillary sample (POCT) was compared with haemoglobin of venous sample analysed by the haematology analyser (Beckman coulter) which was considered as gold standard.

The Effectiveness of a Collector Bag for Measurement of Post-partum Hemorrhage
African Journal of Reproductive Health, 2017
The aim of the study was to assess sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) of collector bag and its correlation with hemoglobin (Hb) and hematocrit (Ht) variations. This study, carried on 100 women referred for admission to labor ward of Shohada hospital in Orumeyeh City, Iran, from April to November, 2007. Serum Hb and Ht were measured after admission; a collecting bag placed under the pelvis just after birth and was weighted after delivery. Hb and Ht were again assessed at 8 hr after delivery. PPH was defined as blood loss ˃500 ml following vaginal delivery. Each 500 ml blood loss accounts for approximately a 3% change in the Ht level or a falling in Hb of 1 g/dl. With this cut off our noted Sensitivity=80%, Specificity=95. 7%, PPV= 88.9% and NPV= 91.8%. The collector bag is a rapid and precise instrument to diagnose of postpartum hemorrhage in the delivery room. It also enables a visual, quantitative and objective estimation of blood loss.
Non-invasive measurement of hemoglobin during cesarean hysterectomy: A case series
International Journal of Obstetric Anesthesia, 2011
Obstetric patients diagnosed with abnormal placentation (placenta accreta, increta or percreta) are at increased risk of major postpartum hemorrhage and cesarean hysterectomy. Obstetric anesthesiologists are primarily involved in intraoperative transfusion management in these cases. Hemoglobin assessment is invaluable for assisting transfusion decision-making during the acute period of obstetric hemorrhage. However, laboratory and point-of-care tests of hemoglobin concentration are time-dependent and intermittent, and do not provide a real-time assessment of change during the acute phase of blood loss. A new non-invasive hemoglobin monitor has been introduced recently, which provides real-time measurement of hemoglobin values (SpHb) using multi-wavelength pulse co-oximetry. We present a review of five patients with suspected abnormal placentation who received SpHb monitoring during cesarean hysterectomy at our institution. We discuss the potential clinical utility of non-invasive hemoglobin monitoring for pregnant patients at high risk of obstetric hemorrhage, and the potential role of SpHb in guiding transfusion therapy.

Background: Assessment of hemoglobin is one of the most reliable indicators for anemia, and is widely used to screen for anemia among pregnant women. The HemoCue ® has been widely used for as a point-of-care device for hemoglobin estimation in health facilities. Previous studies showed contradictory results regarding the accuracy of HemoCue ® . Methods: This was a hospital-based cross sectional study carried-out among pregnant women at Khartoum hospital in Sudan to find out whether the measurement of hemoglobin concentration by HemoCue ® using venous or capillary samples was comparable to that of the automated hematology analyzer as standard. Bland and Altman method was used to compare the measurements with an acceptable difference of ± 1.0 g/dl. Results: Among the 108 subjects in this study the mean (SD) level of hemoglobin level using HemoCue ® venous sample, HemoCue ® capillary sample and automated hematology analyzer were 12.70 (1.77), 12.87 (2.04) and 11.53 (1.63) g/dl, respectively. Although the correlations between the measurements were all significant there was no agreement between HemoCue ® and automated hematology analyzer. The bias + SD (limits of agreement) for HemoCue ® venous versus hematology analyzer was 1.17 ± 1.57 (-1.97, 4.31) g/dl, HemoCue ® capillary versus hematology analyzer was 1.34 ± 1.85 (-2.36, 5.04) g/dl, and HemoCue ® venous versus HemoCue ® capillary samples was 017 ± 1.90 and (3.97-3.63) g/dl. Conclusion: Hemoglobin concentration assessment by HemoCue ® using either venous or capillary blood samples has shown unacceptable agreement with automated hematology analyzer.

BACKGROUND: The prevalence of anaemia is higher among women, including pregnant women. The estimation was about 24.8% of the population in the world suffering anaemia. Anaemia during pregnancy is a big problem because it can contribute morbidity and mortality, either in mother or newborn. The impacts of anaemia during pregnancy included post-partum haemorrhage, low birth weight (LBW), preterm delivery, and low Appearance, Pulse, Grimace, Activity, Respiration (APGAR) score. AIM: This study aimed to determine the correlation between haemoglobin concentration during pregnancy and the outcome of mothers and newborns. METHODS: It was a cohort study that included 200 pregnant women in second or third trimester at antenatal care of Sundari General Hospital Outpatient Clinic on February until September 2018. The participants were interviewed using a questionnaire, and their blood was checked to measure haemoglobin concentration using portable Easy Touch Hemoglobinometer. In the next three ...

This study aimed to determine the sensitivity and specificity test of hemoglobin examination on pregnant women using Hemoglobinometer and Hematology Analyzer devices. The research method used a quantitative approach with the type of research being analytic observational research. The type of data used was primary data in the form of research results and secondary data in the form of data obtained from literature, books and documents. The sampling technique in this study was a purposive sampling technique, with a total sample of 73 people taken from the Kota Utara Public Health Center and Toto Kabila Regional General Hospital. The results showed that the hemoglobinometer has a sensitivity of 81% and a specificity of 100%, while the hematology analyzer has a sensitivity of 98% and a specificity of 100%.
