Abstract
BACKGROUND The Kleihauer-Betke (KB) test allows the detection of fetal red blood cells (containing fetal hemoglobin, HbF) in the maternal blood to identify and quantify potential fetal-maternal hemorrhages. In certain cases, detecting fetal red blood cells with conventional staining is difficult. False-positive results or overestimation of the quantity of fetal red blood cells may occur in cases of maternal hemoglobinopathy. In this study, we developed a new staining protocol to facilitate the reading of difficult smears and improve the precision of the quantification of fetal red blood cells; we also analyzed the performance of this new method. This study assessed blood samples with and without hemoglobin abnormalities, which present difficulties when interpreting the KB test. METHODS The new staining formula is based on an improved elution technique and the use of a different stain instead of hematoxylin. To test this staining method, 16 samples from patients with abnormal hemoglobin electrophoresis and 14 samples from patients with normal hemoglobin electrophoresis were analyzed using the KB test with the classical staining method and the new staining method. In addition, a second series was prepared using the same samples spiked with fetal red blood cells from newborn blood, to compare the accuracy of the two methods in identifying fetal red blood cells. RESULTS In the 60 slides analyzed with both staining methods, we found that the new technique improved the accuracy from 78 to 85%; lowered the coefficient of variation between the operators, which decreased from 20.7% to 12.7%; increased the specificity in our population from 56 to 70%; and decreased the number of false-positive cases by 30%. CONCLUSIONS We successfully developed a new staining technique that facilitates the reading of difficult slides and improves the specificity of the detection of fetal red blood cells. This technique is recommended as a secondary method to use before sending the sample for additional exploration.

Abstract
INTRODUCTION Trauma during pregnancy is the leading cause of non-obstetric maternal death and complicates up to 5%-7% of pregnancies. This systematic review without meta-analysis explores the current literature regarding the assessment and management of pregnant trauma patients to provide evidence-based recommendations to guide the general surgeon regarding the prognostic value of laboratory testing including Kleihauer-Betke testing, duration of maternal and fetal monitoring, the use of tranexamic acid, the safety of radiographic studies, and the utility of perimortem cesarean section to improve maternal and fetal mortality. MATERIALS AND METHODS A systematic search of MEDLINE (Ovid), the Cochrane Library (Wiley), and Embase (Elsevier) was performed. The reference lists of included studies were reviewed for relevant citations. RESULTS Of the 45 studies included in this review, there was reasonable evidence to suggest that the minimally injured pregnant trauma patient should be observed for a minimum of 4 h, CT scans to rule out traumatic injury are necessary and safe, perimortem cesarean sections should be performed as soon as maternal cardiac arrest occurs. CONCLUSIONS We recommend delivery by perimortem cesarean section as soon as possible after maternal cardiac arrest, to provide TXA to the hemorrhaging pregnant trauma patient, to obtain trauma CT scans as indicated, and to observe the injured pregnant patient for a minimum of at least 4 h. Additional high-quality studies focusing on the prognostic potential of KB tests and other laboratory studies are needed.

Abstract
Trauma is the leading nonobstetric cause of maternal death and affects 1 in 12 pregnancies in the United States. Adhering to the fundamentals of the advanced trauma life support (ATLS) framework is the most important component of care in this patient population. Understanding the significant physiologic changes of pregnancy, especially with regard to the respiratory, cardiovascular, and hematologic systems, will aid in airway, breathing, and circulation components of resuscitation. In addition to trauma resuscitation, pregnant patients should undergo left uterine displacement, insertion of 2 large bore intravenous lines placed above the level of the diaphragm, careful airway management factoring in physiologic changes of pregnancy, and resuscitation with a balanced ratio of blood products. Early notification of obstetric providers, initiation of secondary assessment for obstetric complications, and fetal assessment should be undertaken as soon as possible but without interference to maternal trauma assessment and management. In general, viable fetuses are monitored by continuous fetal heart rate for at least 4 hours or more if abnormalities are detected. Moreover, fetal distress may be an early sign of maternal deterioration. When indicated, imaging studies should not be limited out of fear for fetal radiation exposure. Resuscitative hysterotomy should be considered in patients approaching 22 to 24 weeks of gestation, who arrive in cardiac arrest or present with profound hemodynamic instability due to hypovolemic shock.

Abstract
BACKGROUND The Western Trauma Association has undertaken publication of best practice clinical practice guidelines on multiple trauma topics. These guidelines are based on scientific evidence, case reports and best practices per expert opinion. Some of the topics covered by this consensus group do not have the ability to have randomized controlled studies completed due to complexity, ethical issues, financial considerations or scarcity of experience. Care of the pregnant trauma patient is one of these clinically complex situations that is based on physiologic data, standard trauma care, trauma care experience and outcomes. METHODS Review of multiple evidence based guidelines, case reports and expert opinion were compiled and reviewed. RESULTS The algorithm is attached with detailed explanation of each step, supported by data if available. CONCLUSIONS Resuscitative and trauma care of the mother is the utmost prioritySTUDY TYPEAlgorithm, expert opinion, consensus. LEVEL OF EVIDENCE III.

Diagnostic accuracy of Kleihauer-Betke (Kb) testing to predict fetal outcomes associated with fetomaternal hemorrhage: a retrospective cohort study. J Perinatol 2022; 42:91-96. [PMID: 34408259 DOI: 10.1038/s41372-021-01185-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 07/24/2021] [Accepted: 07/29/2021] [Indexed: 11/08/2022]
Abstract
OBJECTIVE To evaluate the diagnostic and screening utility of Kleihauer-Betke (KB) testing as a triage tool in predicting adverse fetal outcomes associated with fetomaternal hemorrhage (FMH). STUDY DESIGN Single center retrospective cohort study evaluated a primary composite outcome of fetal complications associated with FMH between KB-negative and KB-positive test groups. Screening tests for sensitivity, specificity, positive predictive value and negative predictive value were determined. RESULTS 641 women (97%) had KB-negative and 22 (3%) had KB-positive tests. The primary composite outcome between KB-negative and KB-positive pregnancies was similar (30% vs. 36%, p = 0.54). Screening exhibited high specificity (97%), however, test sensitivity was poor (4%) with only moderate positive and negative predictive values (36.4 and 69.7%). CONCLUSION Fetal outcomes associated with FMH were not significantly different between KB-positive and KB-negative test cohorts; KB testing offers no diagnostic precision in the emergency triage evaluation of women with suspected FMH.

Abstract
OBJECTIVE To assess whether positive flow cytometry quantification of fetal red blood cells is associated with adverse maternal and neonatal outcomes in cases of mild trauma during pregnancy. STUDY DESIGN A retrospective database study was conducted at a single tertiary center between 2013 and 2019. All pregnant women with viable gestation involved in trauma who underwent flow cytometry quantification of fetal red blood cells were included in the study. Flow cytometry was considered positive (≥0.03/≥30 ml). Composite adverse maternal and neonatal outcome was defined as one or more of the following: intrauterine fetal death, placental abruption, pre-term birth <37 weeks of gestation, immediate premature rupture of the membranes, and immediate delivery following trauma. Univariate analysis was performed followed by multivariate logistic regression analysis controlling for potential confounders, to assess the role of flow cytometry in predicting adverse maternal and neonatal outcome. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated. RESULTS During the study period 1023 women met inclusion and exclusion criteria. The mechanisms of injury were motor vehicle accident in 387 women (38%), falls in 367 (36%), direct abdominal injury in 353 (35%) and in 14 women (1%) other mechanism of injury. Flow cytometry was considered positive (≥0.03/≥30 ml) in 119 women (11.6%) with median result of 0.03 [0.03-0.04], and negative in 904 women (88.4%) ((≤0.03/≤30 ml) with median result of 0.01 [0.01-0.02]. Composite adverse outcome occurred in 8% of the women involved in trauma during pregnancy, with no difference between the groups with vs. without positive flow cytometry (4.2% vs. 8.5%; p = 0.1). Positive flow cytometry was not associated with any adverse maternal or neonatal outcome. This was confirmed on multivariate analysis controlling for potential confounders. CONCLUSION Flow cytometry result is not related to adverse maternal and fetal/neonatal outcome of women involved in minor trauma during pregnancy. We suggest that flow cytometry should not be routinely assessed in pregnant women involved in minor trauma.

Abstract
Pelvic ring injuries (PRI) are among the most difficult injuries to deal with in orthopedic trauma. When these injuries are accompanied by hemodynamic instability their management becomes significantly more complex. A methodical assessment and expeditious triage are required for these patients followed by adequate resuscitation. A major triage decision is whether these patients should undergo arterial embolization in the angiography suit or prompt packing and pelvic stabilization in the operating room. Patient characteristics, fracture type and injury characteristics are taken into consideration in the decision-making process. In this review we discuss the acute evaluation, triage and management of PRIs associated with hemodynamic instability. An evidence based and protocol driven approach is necessary in order to achieve optimal outcomes in these patients.

Abstract
CONTEXT.— The Kleihauer-Betke (KB) test is validated for estimating the dose of Rh immune globulin needed for Rh-negative pregnant females. However, some clinicians are also ordering the test for Rh-positive women. The degree to which this practice occurs is unknown. OBJECTIVE.— To evaluate the number of laboratories that perform the KB test on Rh-positive pregnant women, and to establish current ordering practices for this indication. DESIGN.— We added 9 supplemental questions regarding KB test use for fetomaternal hemorrhage to the 2016 College of American Pathologists proficiency test survey. We also reviewed the available literature regarding the diagnostic utility of the KB test for Rh-positive women. RESULTS.— A total of 1578 surveys were evaluated and revealed that 52% (824) of respondents perform these tests for Rh-positive women, and more than 50% (440 of 819; 53.7%) of these laboratories report that the results for Rh-positive women are treated as important or very important. CONCLUSIONS.— The KB test is commonly used for Rh-positive women, and the information obtained from the test is considered as urgent and important. However, the available literature in support of this practice is still nonconclusive.

Abstract
Acute abdomen in pregnancy represents a unique diagnostic and therapeutic challenge. Acute abdominal pain in pregnancy can occur due to obstetric factors as well for reasons that are unrelated to pregnancy. The diagnostic approach of acute abdomen during pregnancy can be tricky owing to the altered clinical presentations brought about by the anatomical and physiological changes of gestation along with the reluctance to use certain radiological investigations for fear of harming the fetus. Delay in diagnosis and treatment can lead to adverse outcomes for both the mother and fetus. In this article, we attempt to review and discuss the various etiologies, the current concepts of diagnosis, and treatment, with a view to developing a strategy for timely diagnosis and management of pregnant women presenting with acute abdominal pain.

Abstract
Fetomaternal hemorrhage (FMH) is a rare condition that requires early diagnosis and appropriate treatment due to its potentially severe consequences. We report a case of massive FMH presenting as decreased fetal movement, fetal hydrops, and intracranial hemorrhage at 24 weeks. Treatment considerations were made and amniocentesis, fetal blood sampling, and fetal blood transfusion via cordocentesis were performed. Recurrent FMH required subsequent fetal transfusion 2 days later. Surveillance was continued twice weekly until the patient delivered a viable infant at 38 weeks after spontaneous labor. Recurrent FMH was unpredictable due to its unclear etiology and absence of precipitating events, however close surveillance proved effective.

Abstract
Background Fetal red blood cells (FRBC) in maternal blood are counted in rhesus-negative women to determine the amount of anti-D immunoglobulin to be administered in the case of a rhesus-positive fetus. In rhesus-positive pregnant women this is done in not always very well-defined indications including trauma, miscarriage, fetal death and diminished fetal movements. The aim of this study is to determine if the detection of FRBC is useful in rhesus-positive pregnant woman. This was done by assessing maternal and fetal characteristics that are more likely to give a positive test. Materials and methods This was a retrospective cohort study. Results A total of 169 FRBC tests were performed in 161 rhesus-positive pregnant women. FRBC were found in 45 (26.6%) of the women. Three patients experienced a miscarriage although their FRBC tests were negative (p = 0.295). Of the seven patients who experienced unexpected stillbirths, three tested positive. The deaths were not less likely to occur if the results had been negative (p = 0.631). There was a statistically significant difference between the different types of trauma indications (p = 0.025): the test was more likely positive if there had been a fall on the ground or staircase or blunt trauma (p = 0.041, 0.026 and 0.018, respectively). FRBC were not more frequently present in the absence of fetal movements (n = 16, p = 0.693). Conclusion FRBC in maternal blood were more likely positive in the case of a fall on the ground, or from a staircase. However, a positive test does not necessarily imply fetal pathology and, therefore, does not contribute to clinical management.

Abstract
OBJECTIVE To evaluate the pertinence of Kleihauer-Betke (KB) test, in case of abdominal trauma during pregnancy in forecast of fetal outcomes, according to trauma severity. METHODS A single-center retrospective study conducted between January 2014 and April 2016 in a maternity type III and a trauma center, which included the pregnant women admitted for abdominal trauma. The trauma's severity was assessed using the guidelines of the Society of Obstetricians and Gynaecologists of Canada. The impact of a positive KB test, defined as>0.1%, was analyzed. Adverse outcome was defined as one or more of the following complications: intrauterine fetal death, placental abruption, pre-term birth<37 weeks of gestation, and fetal or neonatal anemia. RESULTS During the study period, 265 pregnancies involved into an abdominal trauma were included: 69% with a minor trauma and 31% with a severe trauma. Of all patients, 5.6% presented a positive KB test, among then 15.4% had an adverse outcome. There was no significant difference in the rate of adverse outcomes in the positive KB group and the KB negative group either in the overall population (P=0.16), in the minor trauma population (P=1) or in the major trauma population (P=0.14). The predictive positive values were respectively in the global population, in the minor trauma group and in the severe trauma group 15.4%, 0% and 25%. CONCLUSIONS The KB test does not seem to be useful in case of trauma during pregnancy to define adverse outcome.

Abstract
PURPOSE The pharmacologic properties of Rhesus (Rh) immune globulin (RhIG) and clinical data on its effectiveness in preventing Rh-antigen alloimmunization in pregnant women are reviewed. SUMMARY RhIG is a human plasma derivative that targets red blood cells (RBCs) positive for Rh(O) antigen (also called D antigen). In the United States and other countries, the widespread use of RhIG has markedly reduced the occurrence of hemolytic disease of the fetus and newborn (HDFN), a devastating condition caused by D-antigen sensitization of a pregnant woman via exposure to fetal RBCs (usually during detachment of the placenta in labor) that results in a maternal immune response leading to severe hemolysis in the fetus. Routine administration of RhIG at 26-30 weeks' gestation and again within 72 hours of delivery has been shown to be highly effective in preventing maternal Rh alloimmunization, with very low rates of D-antigen sensitization (in the range of 0-2.2%) reported in multiple studies of at-risk women. The four RhIG products currently available in the United States have common clinical indications but differ in certain attributes. Pharmacists can play an important role in guiding other clinicians on the rationale for the use of RhIG, important differences between products, and appropriate timing of RhIG therapy. CONCLUSION Routine administration of RhIG to women at risk for Rh alloimmunization is clinically effective and has made HDFN a rare clinical event. The available RhIG products are not the same and should be carefully reviewed to ensure that they are administered safely.

Abstract
OBJECTIVE Physical trauma affects 1 in 12 pregnant women and has a major impact on maternal mortality and morbidity and on pregnancy outcome. A multidisciplinary approach is warranted to optimize outcome for both the mother and her fetus. The aim of this document is to provide the obstetric care provider with an evidence-based systematic approach to the pregnant trauma patient. OUTCOMES Significant health and economic outcomes considered in comparing alternative practices. EVIDENCE Published literature was retrieved through searches of Medline, CINAHL, and The Cochrane Library from October 2007 to September 2013 using appropriate controlled vocabulary (e.g., pregnancy, Cesarean section, hypotension, domestic violence, shock) and key words (e.g., trauma, perimortem Cesarean, Kleihauer-Betke, supine hypotension, electrical shock). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English between January 1968 and September 2013. Searches were updated on a regular basis and incorporated in the guideline to February 2014. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). BENEFITS, HARMS, AND COSTS This guideline is expected to facilitate optimal and uniform care for pregnancies complicated by trauma. Summary Statement Specific traumatic injuries At this time, there is insufficient evidence to support the practice of disabling air bags for pregnant women. (III) Recommendations Primary survey 1. Every female of reproductive age with significant injuries should be considered pregnant until proven otherwise by a definitive pregnancy test or ultrasound scan. (III-C) 2. A nasogastric tube should be inserted in a semiconscious or unconscious injured pregnant woman to prevent aspiration of acidic gastric content. (III-C) 3. Oxygen supplementation should be given to maintain maternal oxygen saturation > 95% to ensure adequate fetal oxygenation. (II-1B) 4. If needed, a thoracostomy tube should be inserted in an injured pregnant woman 1 or 2 intercostal spaces higher than usual. (III-C) 5. Two large bore (14 to 16 gauge) intravenous lines should be placed in a seriously injured pregnant woman. (III-C) 6. Because of their adverse effect on uteroplacental perfusion, vasopressors in pregnant women should be used only for intractable hypotension that is unresponsive to fluid resuscitation. (II-3B) 7. After mid-pregnancy, the gravid uterus should be moved off the inferior vena cava to increase venous return and cardiac output in the acutely injured pregnant woman. This may be achieved by manual displacement of the uterus or left lateral tilt. Care should be taken to secure the spinal cord when using left lateral tilt. (II-1B) 8. To avoid rhesus D (Rh) alloimmunization in Rh-negative mothers, O-negative blood should be transfused when needed until cross-matched blood becomes available. (I-A) 9. The abdominal portion of military anti-shock trousers should not be inflated on a pregnant woman because this may reduce placental perfusion. (II-3B) Transfer to health care facility 10. Transfer or transport to a maternity facility (triage of a labour and delivery unit) is advocated when injuries are neither life- nor limb-threatening and the fetus is viable (≥ 23 weeks), and to the emergency room when the fetus is under 23 weeks' gestational age or considered to be non-viable. When the injury is major, the patient should be transferred or transported to the trauma unit or emergency room, regardless of gestational age. (III-B) 11. When the severity of injury is undetermined or when the gestational age is uncertain, the patient should be evaluated in the trauma unit or emergency room to rule out major injuries. (III-C) Evaluation of a pregnant trauma patient in the emergency room 12. In cases of major trauma, the assessment, stabilization, and care of the pregnant women is the first priority; then, if the fetus is viable (≥ 23 weeks), fetal heart rate auscultation and fetal monitoring can be initiated and an obstetrical consultation obtained as soon as feasible. (II-3B) 13. In pregnant women with a viable fetus (≥ 23 weeks) and suspected uterine contractions, placental abruption, or traumatic uterine rupture, urgent obstetrical consultation is recommended. (II-3B) 14. In cases of vaginal bleeding at or after 23 weeks, speculum or digital vaginal examination should be deferred until placenta previa is excluded by a prior or current ultrasound scan. (III-C) Adjunctive tests for maternal assessment 15. Radiographic studies indicated for maternal evaluation including abdominal computed tomography should not be deferred or delayed due to concerns regarding fetal exposure to radiation. (II-2B) 16. Use of gadolinium-based contrast agents can be considered when maternal benefit outweighs potential fetal risks. (III-C) 17. In addition to the routine blood tests, a pregnant trauma patient should have a coagulation panel including fibrinogen. (III-C) 18. Focused abdominal sonography for trauma should be considered for detection of intraperitoneal bleeding in pregnant trauma patients. (II-3B) 19. Abdominal computed tomography may be considered as an alternative to diagnostic peritoneal lavage or open lavage when intra-abdominal bleeding is suspected. (III-C) Fetal assessment 20. All pregnant trauma patients with a viable pregnancy (≥ 23 weeks) should undergo electronic fetal monitoring for at least 4 hours. (II-3B) 21. Pregnant trauma patients (≥ 23 weeks) with adverse factors including uterine tenderness, significant abdominal pain, vaginal bleeding, sustained contractions (> 1/10 min), rupture of the membranes, atypical or abnormal fetal heart rate pattern, high risk mechanism of injury, or serum fibrinogen < 200 mg/dL should be admitted for observation for 24 hours. (III-B) 22. Anti-D immunoglobulin should be given to all rhesus D-negative pregnant trauma patients. (III-B) 23. In Rh-negative pregnant trauma patients, quantification of maternal-fetal hemorrhage by tests such as Kleihauer-Betke should be done to determine the need for additional doses of anti-D immunoglobulin. (III-B) 24. An urgent obstetrical ultrasound scan should be undertaken when the gestational age is undetermined and need for delivery is anticipated. (III-C) 25. All pregnant trauma patients with a viable pregnancy who are admitted for fetal monitoring for greater than 4 hours should have an obstetrical ultrasound prior to discharge from hospital. (III-C) 26. Fetal well-being should be carefully documented in cases involving violence, especially for legal purposes. (III-C) Obstetrical complications of trauma 27. Management of suspected placental abruption should not be delayed pending confirmation by ultrasonography as ultrasound is not a sensitive tool for its diagnosis. (II-3D) Specific traumatic injuries 28. Tetanus vaccination is safe in pregnancy and should be given when indicated. (II-3B) 29. Every woman who sustains trauma should be questioned specifically about domestic or intimate partner violence. (II-3B) 30. During prenatal visits, the caregiver should emphasize the importance of wearing seatbelts properly at all times. (II-2B) Perimortem Caesarean section 31. A Caesarean section should be performed for viable pregnancies (≥ 23 weeks) no later than 4 minutes (when possible) following maternal cardiac arrest to aid with maternal resuscitation and fetal salvage. (III-B).

Abstract
BACKGROUND We evaluated the relationship between minor trauma during pregnancy and elevated maternal serum α-fetoprotein level. METHODS This is a retrospective review of pregnant patients admitted to Fukui Prefectural Hospital with trauma during a 10-year period. Charts were reviewed for maternal age, gestational age, injury characteristics, Injury Severity Score, the presence of abdominal pain, systolic pressure and heart rate on arrival, fetal hemoglobin level, and maternal serum α-fetoprotein (MSAFP) concentration on arrival. RESULTS Fifty-one pregnant patients with any trauma were treated at Fukui Prefectural Hospital. All patients were hemodynamically stable and had minor trauma. An adverse pregnancy outcome occurred in three patients (5%). One patient's fetus had a left kidney injury. Intrauterine fetal death occurred in two patients. The time from injury to fatal death was 180 minutes in one patient and 18 hours in the other patient. The mean ± SD fetal hemoglobin was 0.57% ± 0.88%. The mean ± SD MSAFP was 511 ng/mL ± 1,263 ng/mL. Three patients with adverse pregnancy outcome had a high MSAFP of greater than 1,000 ng/mL. CONCLUSION High level of MSAFP may be a predictor of poor fetal outcome following trauma during pregnancy regardless of the severity of the trauma or the mother's hemodynamic status. LEVEL OF EVIDENCE Epidemiologic study, level V.

Abstract
The management of a pregnant woman with an acute non-obstetrical disease must be made in narrow collaboration with an obstetrician. This one must be warned from the beginning of the care of the patient. In a pregnant woman, any acute medical, surgical or traumatic non-obstetrical disease can have obstetrical consequences. The diagnostic and therapeutic management of an acute non-obstetrical disease can have iatrogenic consequences during pregnancy. The most often described risks are early pregnancy loss, intra-uterine fetal death, placenta abruption, direct fetal hurts, preterm labor, prematurity and its complications. Obstetrical complications can induce maternal and neonatal life-threatening risks. Simple and easily accessible examinations in emergency allow detecting the obstetrical consequences of an acute non-obstetrical disease. During the management of an acute non-obstetrical disease in a pregnant woman, the induced obstetrical consequence of the disease can require emergency action of the obstetrician in conditions associated with maternal life-threatening risk. During the management of an acute non-obstetrical disease in a pregnant woman, once the mother condition was stabilized, the obstetrician had to estimate the fetal consequences and to adapt his or her therapeutic attitude. He or she sets up the fetal and placental surveillance adapted to the obstetrical risks and decides on the duration of this surveillance.

Abstract
Trauma during pregnancy has presented very unique challenges over the centuries. From the first report of Ambrose Pare of a gunshot wound to the uterus in the 1600s to the present, there have existed controversies and inconsistencies in diagnosis, management, prognostics, and outcome. Anxiety is heightened by the addition of another, smaller patient. Trauma affects 7% of all pregnancies and requires admission in 4 of 1000 pregnancies. The incidence increases with advancing gestational age. Just over half of trauma during pregnancy occurs in the third trimester. Motor vehicle crashes comprise 50% of these traumas, and falls and assaults account for 22% each. These data were considered to be underestimates because many injured pregnant patients are not seen at trauma centers. Trauma during pregnancy is the leading cause of nonobstetric death and has an overall 6% to 7% maternal mortality. Fetal mortality has been quoted as high as 61% in major trauma and 80% if maternal shock is present. The anatomy and physiology of pregnancy make diagnosis and treatment difficult.

Abstract
In the United States, trauma is the leading nonobstetric cause of maternal death. The principal causes of trauma in pregnancy include motor vehicle accidents, falls, assaults, homicides, domestic violence, and penetrating wounds. The managing team evaluating and coordinating the care of the pregnant trauma patient should be multidisciplinary so that it is able to understand the physiologic changes in pregnancy. Blunt trauma to the abdomen increases the risk of placental abruption. Evaluation of the pregnant trauma patient requires a primary and secondary survey with emphasis on airway, breathing, circulation, and disability. The use of imaging studies, invasive hemodynamics, critical care medications, and surgery, if necessary, should be individualized and guided by a coordinating team effort to improve maternal and fetal conditions. A clear understanding of gestational age and fetal viability should be documented in the record.

Abstract
Trauma is the leading cause of maternal death in the United States. Nurses must optimize the well-being of 2 patients in the pregnant trauma patient. Rapid assessment, initiating immediate interventions for life-threatening injuries, and transport to a trauma center are critical to optimize maternal and fetal outcome. Understanding these factors can facilitate an effective resuscitation and optimize the outcome for both mother and baby.

Abstract
Trauma complicates approximately 6-7% of all pregnancies and is associated with significant maternal and fetal morbidity and mortality. While the majority of trauma is minor, it is minor trauma that contributes to the majority of fetal mortality. Since virtually every organ system is affected anatomically and physiologically by pregnancy, it is important for healthcare providers who care for trauma victims to be aware of these changes. While assessment and resuscitation considers the existence of two patients, stabilization of the mother takes priority. Diagnostic and radiologic procedures should be used as indicated, with fetal exposure to radiation limited as much as possible. Management of the pregnant trauma victim requires a multidisciplinary approach in order to optimize outcome for mother and fetus. This review discusses the epidemiology, assessment and treatment of pregnant trauma patients and reviews areas where prevention efforts may be focused.

Abstract
The pregnant woman who has experienced trauma will need to be transferred to an appropriate setting once she is stabilized. Nursing has evolved into many specialty areas with specific sets of skills developed to care for women in these areas. The trauma team and the intensive care unit team will most likely be uncomfortable with the pregnant woman. The perinatal team may be uncomfortable with the injuries or illness that brought the woman to the trauma unit. Together the combined knowledge of all teams can provide for safe care of the woman and fetus and prevent injury occurring to them. Collaborative care is part of the overall plan of care, which follows a formal plan already established by the leadership teams of the 2 units. The purpose of this article is to review collaborative care in the intensive care unit and to provide an overview of the nursing skill sets necessary to care for the pregnant trauma woman.

Abstract
The care of the pregnant trauma patient provides unique challenges and holds profound implications for both fetal and maternal outcomes. The management of these patients is influenced by unique anatomic and physiologic changes, increased concern for deleterious radiation and medication exposures, and the need for multidisciplinary care. This article reviews the critical features necessary in the assessment, diagnosis, treatment, and disposition of pregnant trauma patients with a focus on recent developments reported in the literature as pertinent to emergency management.

Abstract
Ten children (six males, four females) with spastic (n=9) and mixed spastic-dyskinetic (n=1) cerebral palsy were born at term to mothers who earlier in the pregnancy had been involved in accidents without suffering overt abdominal injury, placental abruption, or premature onset of labour. At follow-up (at ages 2-24y), Gross Motor Function Classification System levels were II (n=7) and V (n=3). Cognitive level was normal in five patients, while learning disability was mild to moderate in two and severe in three. Magnetic resonance imaging of the brain in all children, assessed blind to the dates of maternal trauma in pregnancy, showed lesions consistent with prenatal vascular insult at the time of the trauma. Feasible mechanisms of brain injury include reduced placental blood flow and/or placental embolization.

Abstract
BACKGROUND Trauma during pregnancy places two lives at risk. Knowledge of risk factors for trauma during pregnancy may improve outcomes. METHODS We reviewed the charts of 188 such patients admitted to a Level I trauma center from 1996 to 2004. A comparison was made of injury severity and outcome from a cohort of nonpregnant female trauma patients selected with a similar temporal occurrence and age range. RESULTS Motor vehicle collisions comprised 160 cases, 67 using a restraint device. Of 84 patients tested, 45 tested positive for intoxicants, 16 positive for 2 or more intoxicants. A significant trend toward less testing through the study period was observed (p = 0.0002). Injury severity was assessed by Revised Trauma Score (RTS). RTS <11 or admission to operating room or intensive care units (OR/ICU) classified patients as severely injured. The six maternal fatalities had an RTS <11 or OR/ICU disposition. Fetal outcomes included 155 live in utero, 18 live births, and 15 fatalities correlating with injury severity by either criteria (p < 0.0001). Of the fetal fatalities, 7 occurred with RTS = 12, but only 3 fatalities occurred in the 147 cases not admitted to OR/ICU. Gestational age correlated (p < 0.0001) with fetal outcomes. The 18 live births had mean gestational ages of 35 +/- 4 weeks as compared with fetal fatalities at 20 +/- 9 weeks, and fetuses alive in utero at 22 +/- 9 weeks gestation. Coagulation tests prothrombin time (PT), international normalized ratio (INR) (both p < 0.008), and partial thromboplastin time (PTT) (p < 0.0001) correlated with maternal outcome. A matched cohort of nonpregnancy trauma cases during the same time frame indicated that, despite a significantly higher percentage of severely injured patients, fewer fatalities occurred. This might reflect a greater risk for the pregnant trauma patient. CONCLUSIONS This study of trauma in pregnancy cases revealed a high percentage with risk behaviors. There was a significant trend toward less intoxicant testing in recent years. Coagulation tests were the most predictive of outcomes. Lower gestational age correlated with fetal demise.

Abstract
Although less than 10% of pregnant patients are likely to experience some type of physical trauma, injury is the leading non-obstetric cause of maternal mortality. The assessment and resuscitation of the injured pregnant patient must take into account the specific needs of both the mother and the foetus. This paper will review the physiology of pregnancy, discuss recent changes in assessment and resuscitation, and identify special injuries and issues specific to the pregnant trauma patient.
