Author information Crit Care. 2011 Aug 12;15(4):227. doi: 10.1186/cc10256. Abstract Critical illness is an uncommon but potentially devastating complication of pregnancy. The majority of pregnancy-related critical care admissions occur postpartum. Antenatally, the pregnant patient is more likely to be admitted with diseases non-specific to pregnancy, such as pneumonia. Pregnancy-specific diseases resulting in ICU admission include obstetric hemorrhage, pre-eclampsia/eclampsia, HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome, amniotic fluid embolus syndrome, acute fatty liver of pregnancy, and peripartum cardiomyopathy. Alternatively, critical illness may result from pregnancy-induced worsening of pre-existing diseases (for example, valvular heart disease, myasthenia gravis, and kidney disease). Pregnancy can also predispose women to diseases seen in the non-pregnant population, such as acute respiratory distress syndrome (for example, pneumonia and aspiration), sepsis (for example, chorioamnionitis and pyelonephritis) or pulmonary embolism. The pregnant patient may also develop conditions co-incidental to pregnancy such as trauma or appendicitis. Hemorrhage, particularly postpartum, and hypertensive disorders of pregnancy remain the most frequent indications for ICU admission. This review focuses on pregnancy-specific causes of critical illness. Management of the critically ill mother poses special challenges. The physiologic changes in pregnancy and the presence of a second, dependent, patient may necessitate adjustments to therapeutic and supportive strategies. The fetus is generally robust despite maternal illness, and therapeutically what is good for the mother is generally good for the fetus. For pregnancy-induced critical illnesses, delivery of the fetus helps resolve the disease process. Prognosis following pregnancy-related critical illness is generally better than for age-matched non-pregnant critically ill patients. PDF Atención crítica materna: ¿qué podemos aprender de la experiencia del paciente? Un estudio cualitativo Maternal critical care: what can we learn from patient experience? A qualitative study Lisa Hinton, Louise Locock, Marian Knight BMJ Open. 2015; 5(4): e006676. Published online 2015 Apr 27. doi: 10.1136/bmjopen-2014-006676 Objective For every maternal death, nine women develop severe maternal morbidity. Many of those women will need care in an intensive care unit (ICU) or high dependency unit (HDU). Critical care in the context of pregnancy poses distinct issues for staff and patients, for example, with breastfeeding support and separation from the newborn. This study aimed to understand the experiences of women who experience a maternal near miss and require critical care after childbirth. Setting: Women and some partners from across the UK were interviewed as part of a study of experiences of near-miss maternal morbidity. Design: A qualitative study, using semistructured interviews. Participants; A maximum variation sample was recruited of 35 women and 11 partners of women who had experienced a severe maternal illness, which without urgent medical attention would have led to her death. 18 of the women were admitted to ICU or HDU. Results; The findings are presented in three themes: being in critical care; being a new mother in critical care; transfer and follow-up after critical care. The study highlights the shock of requiring critical care for new mothers and the gulf between their expectations of birth and what actually happened; the devastation of being separated from their baby, how valuable access to their newborn was, if possible, and the importance of breast feeding; the difficulties of transfer and the need for more support; the value of follow-up and outreach to this population of critical care patients. Conclusions: While uncommon, critical illness in pregnancy can be devastating for new mothers and presents a challenge for critical care and maternity staff. This study provides insights into these challenges and recommendations for overcoming them drawn from patient experiences.

Paro cardiaco y embarazo / Cardiac arrest and pregnancy

Octubre 12, 2017. No. 2839

Fundamentos en el paro cardíaco durante la cesárea Essentials in cardiac arrest during cesarean section. van Liempt SW, Stoecklein K, Tjiong MY, Schwarte LA, de Groot CJ, Teunissen PW. Author information Clin Pract. 2015 Feb 17;5(1):668. doi: 10.4081/cp.2015.668. eCollection 2015 Jan 28. Abstract Cardiac arrest during cesarean section is very rare. Obstetrical teams have low exposure to these critical situations necessitating frequent rehearsal and knowledge of its differential diagnosis and treatment. A 40-year-old woman pregnant with triplets underwent cesarean sections because of vaginal bleeding due to a placenta previa at 35.2 weeks of gestation. Spinal anesthesia was performed. Asystole occurred during uterotomy. Immediate resuscitation and delivery of the neonates eventually resulted in good maternal and neonatal outcomes. The differential diagnosis is essential and should include obstetric and non-obstetric causes. We describe the consideration of Bezold Jarisch reflex and amniotic fluid embolism as most appropriate in this case.

Benson MD1, Padovano A2, Bourjeily G3, Zhou Y4. Author information EBioMedicine. 2016 Apr;6:253-257. doi: 10.1016/j.ebiom.2016.02.042. Epub 2016 Mar 2. Abstract INTRODUCTION: The current approach to, cardiopulmonary resuscitation of pregnant women in the third trimester has been to adhere to the "four-minute rule": If pulses have not returned within 4min of the start of resuscitation, perform a cesarean birth so that birth occurs in the next minute. This investigation sought to re-examine the evidence for the four-minute rule. METHODS: A literature review focused on perimortem cesarean birth was performed using the same key words that were used in formulating the "four-minute rule." Maternal and neonatal injury free survival rates as a function of arrest to birth intervals were determined, as well as actual incision to birth intervals. RESULTS: Both maternal and neonatal injury free survival rates diminished steadily as the time interval from maternal arrest to birth increased. There was no evidence for any specific survival threshold at 4min. Skin incision to birth intervals of 1min occurred in only 10% of women. CONCLUSION: Once a decision to deliver is made, care providers should proceed directly to Cesarean birth during maternal cardiac arrest in the third trimester rather than waiting for 4min for restoration of the maternal pulse. Birth within 1min from the start of the incision is uncommon in these circumstances.

Costarr. Cardiol. 2013 Julio-Diciembre, Volumen 15, N.º 2 Resumen El paro cardíaco en el embarazo presenta un escenario único en el que están incluidos dos pacientes: la madre y el feto. El manejo de este escenario requiere de un equipo multidisciplinario incluyendo especialistas en anestesia, obstetricia, neonatología, cardiología y en ocasiones cirugía cardíaca. Los protocolos de soporte vital básico y soporte cardíaco avanzado deben ser implementados, sin embargo, dados los cambios anatómicos y fisiológicos que ocurren en el embarazo, algunas modificaciones en los algoritmos son fundamentales. La evidencia existente acerca del manejo del paro cardíaco en el embarazo es relativamente insuficiente, sin estudios randomizados, por lo tanto las recomendaciones son basadas en pequeños estudios de cohorte y reportes de casos, además de la opinión de los expertos. En esta revisión hablaremos del paro cardíaco en el embarazo, sus implicaciones y el manejo adecuado por parte del equipo multidisciplinario, además del tiempo en el que se debe realizar la cesárea en caso de no retorno de circulación espontánea.

Falla respiratoria y embarazo / Respiratory failure in pregnancy.

Octubre 6, 2017. No. 2833

Falla respiratoria aguda en el embarazo Acute respiratory failure in pregnancy. Lapinsky SE1. Author information Obstet Med. 2015 Sep;8(3):126-32. doi: 10.1177/1753495X15589223. Epub 2015 Jun 10. Abstract Respiratory failure affects up to 0.2% of pregnancies, more commonly in the postpartum period. Altered maternal respiratory physiology affects the assessment and management of these patients. Respiratory failure may result from pregnancy-specific conditions such as preeclampsia, amniotic fluid embolism or peripartum cardiomyopathy. Pregnancy may increase the risk or severity of other conditions, including thromboembolism, asthma, viral pneumonitis, and gastric acid aspiration. Management during pregnancy is similar to the nonpregnant patient. Endotracheal intubation in pregnancy carries an increased risk, due to airway edema and rapid oxygen desaturation following apnea. Few data are available to direct prolonged mechanical ventilation in pregnancy. Chest wall compliance is reduced, perhaps permitting slightly higher airway pressures. Optimizing oxygenation is important, but data on the use of permissive hypercapnia are limited. Delivery of the fetus does not always improve maternal respiratory function, but should be considered if benefit to the fetus is anticipated.

Author information J Formos Med Assoc. 2017 May 17. pii: S0929-6646(17)30143-2. doi: 10.1016/j.jfma.2017.04.023. [Epub ahead of print] Abstract BACKGROUND: Obstetric patients comprise a limited portion of intensive care unit patients, but they often present with unfamiliar conditions and exhibit the potential for catastrophic deterioration. This study evaluated the maternal and neonatal outcomes of respiratory failure during pregnancy. METHODS: Information on 71 patients at >25 weeks gestation in the ICU with respiratory failure was recorded between 2009 and 2013. The characteristics and outcomes of mothers and fetuses were determined through a retrospective chart review and evaluated using Student's t test, chi-square test, and Fisher's exact test. RESULTS: The leading causes of respiratory failure were postpartum hemorrhage and severe preeclampsia in the obstetric causes group and pneumonia in the nonobstetric causes group during pregnancy and the peripartum period. The non-obstetric causes group exhibited a higher incidence of acute respiratory distress syndrome and renal replacement therapy as well as requiring more ventilator days. The patients in the obstetric causes group showed significant improvement after delivery in the partial pressure of arterial oxygen to the fraction of inspired oxygen and peak inspiratory pressure decrease. Both groups exhibited high incidences of neonatal respiratory distress syndrome. Neonatal complications resulting from meconium aspiration syndrome (MAS) and sepsis were more common in the non-obstetric causes group; however, neurological development impairment was more common in the obstetric causes group. CONCLUSION: Obstetric cause was associated with longer ventilator free days and fewer episodes of ARDS after delivery. Neonatal complications resulting from different etiologies of respiratory failure were found to differ.

Trombocitopenia y embarazo / Thrombocytopenia in pregnancy

Septiembre 19, 2017. No. 2816

Trombocitopenia en el embarazo. Patogénesis y abordaje diagnóstico Thrombocytopenia in pregnancy - pathogenesis and diagnostic approach. Jodkowska A1, Martynowicz H1, Kaczmarek-Wdowiak B1, Mazur G1. Author information Postepy Hig Med Dosw (Online). 2015 Nov 12;69:1215-21. Abstract Thrombocytopenia (TP) affects 7-10% of pregnant women. It occurs 4 times more frequently in pregnancy than in the non-pregnant women population. Women with thrombocytopenia in pregnancy are a heterogeneous and poorly known group. There are several possible causes of thrombocytopenia in pregnancy. The most common are: gestational thrombocytopenia (GE) (60-75%), preeclampsia (PE) and HELLP(hemolysis, elevated liver enzymes, low platelets) syndrome associated TP (21%), and idiopathic immune thrombocytopenia (ITP) (3-10%). Although thrombocytopenia diagnosed in pregnancy in most cases has a mild course, it has also been reported to be associated with a higher rate of preterm birth and premature detachment of the placenta. Some cases of severe thrombocytopenia with systemic involvement are associated with high risk of serious perinatal complications and require early diagnosis, careful clinical monitoring and medical treatment. The differential diagnosis and proper assessment of clinical risk of TP during pregnancy may be of great concern. The article discusses these issues, focusing on pathophysiology of TP in pregnancy.
