“…Other methods for the intraoperative recording of blood loss are rarely described and have not yet been sufficiently tested. Ultrasound of the inferior vena cava [20,84,85], contrast enhanced ultrasound (CEUS) [86], hemodynamic esophageal Doppler monitoring [19], near-infrared spectroscopy [87] or continuous non-invasive intraoperative Hb monitoring [23,88,89] for intraoperative detection of blood loss have been investigated. None of these methods represents a valid technique for blood loss detection.…”

“…The risk of bias due to confounders was increased in the majority of the studies. The selection of participants in study groups showed an increased risk of bias in four studies [19][20][21][22] and an unclear risk of bias in two studies [23,24]. The documentation and endpoint assessment were adequately described in most of the studies.…”

Estimating intraoperative blood loss is one of the daily challenges for clinicians. Despite the knowledge of the inaccuracy of visual estimation by anaesthetists and surgeons, this is still the mainstay to estimate surgical blood loss. This review aims at highlighting the strengths and weaknesses of currently used measurement methods. A systematic review of studies on estimation of blood loss was carried out. Studies were included investigating the accuracy of techniques for quantifying blood loss in vivo and in vitro. We excluded nonhuman trials and studies using only monitoring parameters to estimate blood loss. A meta-analysis was performed to evaluate systematic measurement errors of the different methods. Only studies that were compared with a validated reference e.g. Haemoglobin extraction assay were included. 90 studies met the inclusion criteria for systematic review and were analyzed. Six studies were included in the meta-analysis, as only these were conducted with a validated reference. The mixed effect meta-analysis showed the highest correlation to the reference for colorimetric methods (0.93 95% CI 0.91–0.96), followed by gravimetric (0.77 95% CI 0.61–0.93) and finally visual methods (0.61 95% CI 0.40–0.82). The bias for estimated blood loss (ml) was lowest for colorimetric methods (57.59 95% CI 23.88–91.3) compared to the reference, followed by gravimetric (326.36 95% CI 201.65–450.86) and visual methods (456.51 95% CI 395.19–517.83). Of the many studies included, only a few were compared with a validated reference. The majority of the studies chose known imprecise procedures as the method of comparison. Colorimetric methods offer the highest degree of accuracy in blood loss estimation. Systems that use colorimetric techniques have a significant advantage in the real-time assessment of blood loss.

“…21 Tomohiro et al found that the ultrasonographic measurement of the IVC diameter was a more accurate marker than vital parameters in predicting serious anemia after birth and identifying patients who will require blood transfusions. 11 On the other hand, Sefidbakht et al 12 and Yanagawa et al 13 showed that the rapid ultrasound performed for bedside IVC evaluation was more sensitive than blood pressure in assessing fluid loss in patients presenting in the emergency department for various types of trauma.…”

“…[8][9][10] Many studies have been conducted to determine the fluid deficit with the help of the IVC diameter and collapsibility index (CI) in the postpartum period, in trauma, cardiogenic-hypovolemic and septic shock patients. [11][12][13] However, to our knowledge, there is no study evaluating preoperative intravascular volume with IVC diameter and CI in the pediatric patient group. Therefore, this study was designed to evaluate changes in IVC diameter and CI of the restriction of preoperative oral nutrition in pediatric patients.…”

Background: Inferior vena cava (IVC) ultrasound measurement is a reliable indicator used in the assessment of intravascular volume status. The aim of this study was to evaluate intravascular volume changes in pediatric patients by measuring the IVC diameter and collapsibility index (CI) in children whose oral feeding was restricted preoperatively. Material and Methods: From May 2018 to October 2018, a total of 55 pediatric patients who were scheduled for surgery were included in this prospective, observational, cohort study. Fasting and satiety IVC diameters and CIs of patients were determined by ultrasonographic evaluation twice: in the preoperative preliminary evaluation, when the patients were satiated, and before surgery, during a fasting period of 6–8 hours. Ultra-sonographic data were recorded and compared between fasting and satiety periods. Results: In the grey scale (B-mode), mean IVC diameter was significantly higher when the patients were satiated, compared to the measurements made just before surgery during the fasting period. In the M-mode, the mean IVC diameter was significantly higher only during the inspiratory phase when the patients were satiated, while during the expiratory phase it was detected to be statistically similar. Mean CI was significantly higher in the immediate preoperative period, compared to the assessment made when satiated. Conclusion: Preoperative ultrasound IVC diameter and CI measurement can be a practical and useful method for evaluating preoperative intravascular volume in children.

[45] продолжили работу по изучению диаметра нижней полой вены в качестве предиктора тяжелой анемии (уровень гемоглобина ≤70 г/л на следующие сутки после родов) при вагинальных родах с кровопотерей ≥500 мл и сравнению с другими параметрами, такими как АШИ, САД, ЧСС. Итогом проведенной работы стал вывод, что диаметр нижней полой вены обладал наибольшей чувствительностью и был наиболее полезным параметром фактической оценки кровопотери после родов [45].…”

Что такое «нормальная» кровопотеря после родов? Общепринятый «нормальный» объем кровопотери в родах и при операции кесарево сечение составляет не более 500 мл и 1000 мл соответственно. Однако такое определение объема кровопотери носит обобщенный характер и не может индивидуально оценить потребность роженицы или родильницы в инфузионной терапии. «Норма» может оказаться достаточно широким понятием при оценке послеродового кровотечения, ведь все роженицы имеют разный волемический статус. Один и тот же объем кровопотери после родов может оказать совершенно разное влияние на состояние и гемодинамические показатели отдельно взятых рожениц. Рассмотрены вопросы оценки изменения волемического статуса рожениц при послеродовом кровотечении, в том числе наиболее существенные ориентиры для правильного определения объема кровопотери. На какие данные должен опираться врач при оценке состояния роженицы, перенесшей послеродовое кровотечение интраоперационно и в послеродовом периоде? Особое внимание уделено мониторингу динамики акушерского шокового индекса как одного из самых простых и в то же время информативных показателей оценки состояния роженицы при послеродовом кровотечении. Рассмотрены вопросы определения необходимости проведения инфузионной терапии при акушерском кровотечении с помощью неинвазивных методов оценки волемического статуса. Отмечено, что зачастую излишняя массивная инфузионная терапия, которая основана лишь на эмпирических расчетах, может принести больше вреда, чем пользы, усилив коагулопатию разведения. Поэтому необходимы новые, более совершенные методы оценки волемического статуса рожениц и родильниц и показаний к инфузионной терапии. Ключевые слова: послеродовое кровотечение, волемический статус роженицы, инфузионная терапия при акушерском кровотечении.
