The authors have no relevant financial interest in the products or companies described in this article. However, if the mother and fetus are ABO incompatible, it is more crucial to quickly perform the KB stain following a stillbirth, as the fetal red blood cells will be eliminated from the maternal bloodstream quickly, causing the KB stain to underestimate the degree of FMH, if any. Copyright 2023, StatPearls Publishing LLC. Manual uterine displacement may allow for more effective chest compressions because it avoids the need to facilitate a total body tilt.16 All standard medications and defibrillation regimens may be used in advanced cardiac life support (ACLS).17 Unique aspects of ACLS include early intubation, removal of all uterine and fetal monitors, and performance of a perimortem cesarean delivery.18 Modifications of resuscitative efforts in pregnancy are listed in eTable A. Perimortem cesarean delivery may save the life of the fetus when performed after 23 to 24 weeks' gestation.19,20 Delivery increases venous return and cardiac output by 25% to 30%, may lead to a clear survival benefit for the mother, and has not been shown to be harmful.16,1922 The American Heart Association recommends considering perimortem cesarean delivery if ACLS has not returned spontaneous circulation within four to five minutes of cardiac arrest.18 Table 2 and eTable B describe considerations based on gestational age and issues related to perimortem cesarean delivery.

This disruption in the placental barrier may occur for many reasons, including intrauterine fetal demise and trauma. Gestational age 20 to 23 weeks: emergency hysterotomy is indicated to enable successful resuscitation but not for survival of the delivered fetus. Once the size of the feto-maternal hemorrhage (FMH) is determined, the appropriate RhIG dose can be calculated and administered to prevent the mother from making anti-D. * If STAT test request is for Rh Development of Highly Polymorphic Pentanucleotide Tandem Repeat Loci with Low Stutter.

Study design: Blood smears were stained and evaluated manually according to the Kleihauer-Betke test. Results showed that laboratories using Kleihauer-Betke overestimated the percentage of fetal RBCs on average by 0.221% more (5.292 total percentage points over 24 instances) (95% CI, 0.213%0.227%), with a standard deviation of 0.190. Testing schedules may vary. It is important to note, however, that such a diagnosis is still not completely conclusive; fetuses losing large quantities of blood over long periods of time are able to compensate for this slower blood loss; since the KB stain tells us nothing with regard to the level of acuity of FMH. 2004 Nov;57(5):1094-8.

The risks of RhIg do not exceed risks associated with any other pooled human product, few incidents of viral transmission have been reported in North America, and RhIg is currently manufactured with viral inactivation products.6 Flow cytometry is currently not feasible for many laboratories owing to the need for special equipment and longer duration of turnaround times, which can impact patient care. Acceptable: Frozen plasma from green-top (lithium heparin) tube, frozen plasma from lavender-top (EDTA) tube or frozen plasma from PPT. Liquid chromatography/tandem mass spectrometry (LC/MS-MS). WebObjective: The purpose of this study was to evaluate the quantification of fetomaternal hemorrhage by the manual and automated microscopic analysis of Kleihauer-Betke stained slides and by flow cytometry. The Kleihauer-Betke test is primarily used to quantify the extent of feto-maternal hemorrhage. g The KleihauerBetke ("KB") test, KleihauerBetke ("KB") stain, Kleihauer test or acid elution test is a blood test used to measure the amount of fetal hemoglobin transferred from a fetus to a mother's bloodstream. + The LOINC codes are copyright 1994-2021, Regenstrief Institute, Inc. and the Logical Observation Identifiers Names and Codes (LOINC) Committee. Methods developed by Schneider and Ludwig[5] and Bartsch' are recommended. [Prevention of fetomaternal rhesus-D allo-immunization. [citation needed], Since fetal and maternal blood cells have the same life expectancy in the maternal bloodstream, it is possible to obtain informative results from a KB stain for a fair period of time after a stillbirth. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). The K-B test can be challenging to interpret, so results may vary from interpreter to interpreter, but it is inexpensive and most hospital laboratories use it. Delivery does result in higher frequency of detection of micro-hemorrhages but this should not confound interpretation of FMH as a possible cause of stillbirth. Laboratory: blood type, Rh factor test, hematocrit measurement, Kleihauer-Betke test, coagulation studies, If greater than 20 weeks' gestation, monitor for contractions, If fewer than three contractions per hour, monitor for four hours, then discharge, If three to seven contractions per hour, monitor for 24 hours, then discharge, All Rh-negative patients should receive Rh immune globulin therapy unless the injury is remote from the uterus (e.g., isolated distal extremity), Perform manual uterine displacement, or 25- to 30-degree left lateral tilt, Decreased chest wall compliance with breast hypertrophy and diaphragmatic elevation, Use cricoid pressure, if assistance is available, Perform compressions higher on the sternum (slightly above center of sternum), Remove fetal and uterine monitors before defibrillation, Loss of adequate cardiac shock dose; produces skin burns at monitor sites, Heimlich maneuver; use chest thrust if unable to encircle the gravid abdomen, Start intravenous therapy above diaphragm, Early tracheal intubation; use short laryngoscope handle and smaller endotracheal tube, Difficult ventilation with pharyngeal edema, breast hypertrophy, diaphragmatic elevation, Consider other etiologies (e.g., magnesium toxicity), Consider left wide paddle, adhesive pad, or breast displacement, Dextrorotation of the heart; breast hypertrophy, Verify endotracheal tube with carbon dioxide detector, Esophageal detector more likely not to reinflate after compression, Tailor ventilator support to oxygenation and ventilation, Perform emergency hysterotomy after four minutes, Decreased aortocaval and venous compression, Continue all maternal resuscitative efforts (cardiopulmonary resuscitation, positioning, defibrillation, and drugs) during and after cesarean delivery. In the second trimester, relatively abundant amniotic fluid volume protects the fetus. Are obstetric personnel immediately available to support the mother after delivery? Using data collected by the College of American Pathologists (CAP) fetal red blood cells (RBCs) detection surveys from 20142019 (24 proficiency testing samples to approximately 50 laboratories using flow cytometry and 1000 laboratories using Kleihauer-Betke) where the recommended RhIg dose was calculated from mean reported values with the CAP RhIg Dose Calculator,3 we compared differences in dose calculation. This value is then used to calculate the total amount of fetal blood in the mothers circulation, so that D-negative mothers may receive appropriate amounts of prophylactic Rh Immune globulin. However, some clinicians are (Press Enter or Space to Go to Landing Page or Press Down to expand Menu), Federally Qualified Health Centers (FQHCs), Combatting Modern Slavery and Human Trafficking Statement. The Kleihauer-Betke (KB) test is validated for estimating the dose of Rh immune globulin needed for Rh-negative pregnant females. Laboratory Testing There is no laboratory test to distinguish between active (alloimmunization) or passive anti-D antibody (RhIG administration) production. J Trauma. After 12-weeks gestational age, a dose of 300 mcg is recommended. Interpretive Use: The Kleihauer-Betke Test is a quantitative test to determine the amount of fetomaternal hemorrhage (FMH) and in the case of Rh negative patients, to determine the number of vials of Rh immune globulin (Rhogam) that will be needed to protect against maternal Rh immunization. Jackson, MS 39216 P Appropriate referrals should be made to community-based advocacy groups for persons who have experienced IPV, and a plan should be made to ensure the safety of the patient and other vulnerable persons living in the household.11, When feasible, patients who have experienced major trauma should be transported to a hospital that has the resources to perform a timely trauma evaluation.3 Because placental abruption has been reported to occur up to 24 hours following trauma, monitoring via tocodynamometry should be continued for a minimum of 24 hours if at least six uterine contractions have occurred or if there are nonreassuring fetal heart rate patterns, vaginal bleeding, significant uterine tenderness, serious maternal injury, or a positive Kleihauer-Betke test result.3,13 If none of these findings are present, the patient may be discharged home with precautions.3 Table 1 provides evaluation and discharge criteria for blunt trauma in pregnancy.9,12, Between 24 and 34 weeks' gestation, if delivery appears imminent, 12 mg of betamethasone should be administered intramuscularly to promote fetal lung maturity, and repeated in 24 hours. F See Plasma Amino Acid Reference Intervals in the Test Resources pages online. The ratio of fetal to maternal cells is recorded, allowing calculation of the volume of fetal blood leaked to the maternal circulation.
