Summary
Maternal cardiac arrest is rare but serious. This study found high survival rates and successful outcomes with rapid resuscitative hysterotomy in a tertiary care setting.
Area of Science:
- Obstetrics and Gynecology
- Critical Care Medicine
- Cardiology
Background:
- Maternal cardiac arrest is a critical obstetric emergency with limited outcome data.
- The feasibility and effectiveness of timely resuscitative hysterotomy are not well-established.
Purpose of the Study:
- To evaluate outcomes of maternal cardiac arrest.
- To assess the feasibility and utility of resuscitative hysterotomy.
Main Methods:
- Retrospective cohort study of 31 pregnant or postpartum patients with in-hospital cardiac arrest.
- Analysis of incidence, return of spontaneous circulation (ROSC), survival rates, and hysterotomy outcomes over 15.5 years.
Main Results:
- Incidence of maternal cardiac arrest was 2 per 10,000 deliveries.
- ROSC was achieved in 87.1% of patients, with 77.4% surviving to discharge.
- Two resuscitative hysterotomies resulted in 100% neonatal survival with a 4-minute code-to-delivery time.
Conclusions:
- High rates of ROSC and survival are achievable in tertiary care settings.
- Rapid resuscitative hysterotomy is feasible and beneficial for maternal cardiac arrest management.

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

400
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...

469
Pericarditis, an inflammation of the pericardium, necessitates diligent nursing management to ensure effective patient care and recovery. The initial step in managing pericarditis is a comprehensive patient medical assessment.The patient reports chest pain aggravated by breathing, coughing, and swallowing, which worsens when lying supine. The pain often improves when sitting up and leaning forward. Additional symptoms may include fever, malaise, and, in severe cases, signs of heart failure.

Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...
