Mitral Valve Prolapse III: Nursing Management

534
The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

Pathophysiology of Diabetes

4.5K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Summary

Retained placenta, a complication of vaginal delivery, is strongly linked to stillbirth. Other risk factors include advanced maternal age and delivery in a teaching hospital.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Reproductive Health

Background:

  • Retained placenta complicates 2-3% of vaginal deliveries, increasing risks of postpartum hemorrhage, infection, and prolonged hospital stays.
  • Current management involves manual or operative placental extraction, which can carry additional risks.

Purpose of the Study:

  • To evaluate risk factors associated with retained placenta in a large US obstetrical cohort.
  • To identify predictors of retained placenta, defined as the absence of the placenta more than 30 minutes after fetal delivery.

Main Methods:

  • Analysis of singleton vaginal deliveries (n=91,291) from the Consortium of Safe Labor (2002-2008).
  • Multivariable logistic regression was used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI) for risk factors.
  • Analyses were stratified by parity and adjusted for confounding factors including maternal age, race, stillbirth, and body mass index.

Main Results:

  • Retained placenta occurred in 1.12% of deliveries.
  • Stillbirth was a significant predictor regardless of parity (aOR 5.67 nulliparous, 4.56 multiparous).
  • Additional risk factors included maternal age ≥30 years, delivery at 24-27 weeks gestation, and delivery in a teaching hospital. Non-Hispanic Black race was protective in nulliparous women.

Conclusions:

  • Stillbirth is a potent risk factor for retained placenta.
  • Potential shared etiologies or intrinsic factors related to stillbirth may contribute to placental retention.
  • Understanding these risk factors can inform clinical management and potentially reduce retained placenta incidence.
