cardiac arrest in pregnant

Carlos Javier Shiraishi Zapata
I report a case of hypotension and bradycardia before spinal anesthesia in a pregnant woman with mild to moderate hypertension treated with nifedipine and methyldopa, scheduled for an elective cesarean delivery. She had the history of neurally-mediated syncopes. Two main factors (increased vagal tone and adverse effects of antihypertensive drugs) could explain the hypotension and bradycardia before spinal anesthesia. Monitoring allowed recognizing the problem and corrected it. Thus, it was avoided a disaster in anesthesia, as hemodynamic changes after spinal anesthesia, they would have joined to previous hypotension and bradycardia, which would have caused even a cardiac arrest...

Despite its use since the 1960s, the safety or effectiveness of adrenaline as a treatment for cardiac arrest has never been comprehensively evaluated in a clinical trial. Although most studies have found that adrenaline increases the chance of return of spontaneous circulation for short periods, many studies found harmful effects on the brain and raise concern that adrenaline may reduce overall survival and/or good neurological outcome. The PARAMEDIC-2 trial seeks to determine if adrenaline is safe and effective in out-of-hospital cardiac arrest...

BACKGROUND: Soft-tissue infections in women with subcutaneous injection drug use are often polymicrobial. CASE: A 21-year-old nulliparous woman presented at 14-15 weeks of gestation with several gluteal abscesses related to subcutaneous injection of heroin. She was well appearing, afebrile, and without findings of systemic illness. After empiric broad-spectrum intravenous antibiotics, same-day incision and drainage was performed. Immediately after the procedure, she developed refractory hypotension, severe tachycardia, pulmonary edema, and leukemoid reaction (white blood cell count 80×10/L)...

In developed countries, the rate of obstetric ICU admissions (admission during pregnancy or the postpartum period) is between 0.5 and 4 per 1000 deliveries and the overall case-fatality rate is about 2%. The most two common causes of obstetric ICU admissions concerned direct obstetric pathologies: obstetric hemorrhage and hypertensive disorders of pregnancy. This review summarized the principles of management of critically ill pregnant patient. Its imply taking care of two patients in the same time. A coordinated multidisciplinary team including intensivists, anesthesiologists, obstetricians, pediatricians and pharmacists is therefore necessary...

BACKGROUND: Maternal resuscitation in the emergency department requires planning and special consideration of the physiologic changes of pregnancy. Perimortem cesarean delivery (PMCD) is a rare but potentially life-saving procedure for both mother and fetus. Emergency physicians should be aware of the procedure's indications and steps because it needs to be performed rapidly for the best possible outcomes. OBJECTIVE: We sought to review the approach to the critically ill pregnant patient in light of new expert guidelines, including indications for PMCD and procedural techniques...

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...

BACKGROUND: Delayed hemolytic transfusion reaction (DHTR) is a life-threatening condition in sickle cell disease (SCD) patients that is frequently complicated by hyperhemolysis. Antibodies resulting from antigen disparity between donors of European ancestry and patients of African ancestry are common, but situations involving antibodies not classically of clinical significance are also encountered. Anti-HI is generally considered to be an innocuous naturally occurring antibody. STUDY DESIGN AND METHODS: We describe two cases of hyperhemolysis with anti-HI and provide details of the reported cases...

Although cardiac arrest in pregnancy is rare, it is important that all individuals involved in the acute care of pregnant women are suitably trained, because the outcome for both mother and fetus can be affected by the management of the arrest. Perimortem caesarean delivery was first described in 715 BC. Initially the procedure was performed principally for religious or political reasons. Although the potential for fetal survival was proposed, it was rarely successful, probably because the delivery was delayed until maternal death was established...

This paper presents a case of a pregnant woman with a history of two cesarean sections. The patient was admitted to the hospital because of vaginal bleeding. The ultrasound revealed a placenta covering the internal os. The placenta was characterized by heterogeneous echogenicity with visible irregular hypoechogenic areas and blurred border between the placenta and the cervix. Rich vascularity was observed on the border of the placenta, urethra and the urinary bladder. Cystoscopy showed severe congestion around the urethra...

The management of cardiac arrest in pregnancy is an important task for the emergency physicians. Some reasons for cardiac arrest are reversible and should be recognized and managed promptly. Cardiopulmonary resuscitation follows general advanced cardiac life support guidelines with several modifications for pregnant women, taking into account the lives of both mother and fetus. Here, we present the case of 23-year-old pregnant patient who came to Guru Nanak Dev Hospital, Amritsar; in shock, had a cardiac arrest, successfully resuscitated in Intensive Care Unit (ICU), delivered by emergency cesarean section and was discharged from ICU on 9(th) day in healthy state...

BACKGROUND: High-quality cardiopulmonary resuscitation (CPR) by laypersons is a key determinant of both outcome and survival for out-of-hospital cardiac arrest. Dispatcher-assisted CPR (telephone-CPR, T-CPR) increases the frequency and correctness of bystander-CPR but results in prolonged time to first chest compressions. However, it remains unclear whether instructions for rescue ventilation and/or chest compressions should be recommended for dispatcher-assisted CPR. OBJECTIVE: The aim of this study was to evaluate both principles of T-CPR with respect to CPR quality...

BACKGROUND: Little is known about the effects of propofol on oxidative stress and its effect on key structures of the contractile apparatus as the myosin light chain 2 (MLC2) and the p38MAPK survival pathway in the preterm heart. We hypothesized that propofol administration could attenuate the hypoxic myocardial injury after birth asphyxia. METHODS: Pregnant ewes were randomized to receive either propofol or isoflurane anesthesia. A total of 44 late-preterm lambs were subjected to in utero umbilical cord occlusion (UCO), resulting in asphyxia and cardiac arrest, or sham treatment...

Cardiac arrest after neuraxial anaesthesia is very well described. Inhibition of the sympathetic efferent system and vagal activation leading to decrease preload and severe bradycardia results in cardiac arrest. Pregnant patients undergoing spinal anaesthesia are at increased risk for vasovagal events due to aortocaval compression and higher level of spinal block. A 36-year-old pregnant woman at 39 weeks presented for an elective caesarean section. She underwent spinal anaesthesia. Immediately after, she had severe bradycardia followed by asystole cardiac arrest...

Magnetic resonance (MR) imaging can provide critical diagnostic and anatomic information while avoiding the use of ionizing radiation, but it has a unique set of safety risks associated with its reliance on large static and changing magnetic fields, high-powered radiofrequency coil systems, and exogenous contrast agents. It is crucial for radiologists to understand these risks and how to mitigate them to protect themselves, their colleagues, and their patients from avoidable harm and to comply with safety regulations at MR imaging sites...

Cardiac arrest during pregnancy is a rare event but it needs rapid and effective cardiopulmonary resuscitation to prevent loss of two lives. In this questionnaire survey, G2010 AHA-BLS Healthcare Provider Course participants answered four questions about CPR caveats which should be considered during pregnancy. The correct answer ratio is generally low among the four questions. Special situation explanation addition such as left uterine displacement in the AHA-BLS healthcare provider course may be needed for the empowerment of knowledge about cardiopulmonary resuscitation during pregnancy...

Out-of-hospital cardiac arrest is a leading cause of death in the United States. Pregnant women are not immune to cardiac arrest, and the treatment of such patients can be difficult. Pregnancy is a relative contraindication to the use of therapeutic hypothermia after cardiac arrest. A 20-year-old woman who was 18 weeks pregnant had an out-of-hospital cardiac arrest. Upon her arrival at the emergency department, she was resuscitated and her circulation returned spontaneously, but her score on the Glasgow Coma Scale was 3...

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...

OBJECTIVE: High quality chest compressions are the cornerstone of effective cardiopulmonary resuscitation (CPR). There is no available method of real time noninvasive hemodynamic measurement and feedback to inform rescuers of the efficacy of compressions. Ultrasound-based measures of blood flow may provide immediate, noninvasive hemodynamic information. Our objective was to determine the feasibility and safety of using ultrasound to measure blood flow on patients with cardiac arrest. METHODS: Study design This was a prospective cohort study in an emergency department setting...
