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...

Area of Science:

  • Obstetrics and Gynecology
  • Biomedical Engineering
  • Public Health

Background:

  • Primary postpartum hemorrhage (PPH) is a leading cause of global maternal mortality.
  • Ethiopia faces high maternal mortality, with PPH contributing significantly, especially during home births.
  • Current visual estimation of blood loss for PPH management is inaccurate and subjective.

Purpose of the Study:

  • To develop an integrated system for accurate postpartum blood loss measurement.
  • To provide precise IV fluid management based on real-time vital signs and blood loss.
  • To improve PPH management in resource-limited settings.

Main Methods:

  • A novel system was designed to collect and measure postpartum blood loss.
  • Continuous monitoring of maternal heart rate and blood pressure was integrated.
  • An automated IV fluid delivery system, regulated by a flow rate sensor and solenoid valve, was developed.

Main Results:

  • A functional prototype was developed and tested, achieving 91.28% accuracy.
  • The cost-effectiveness was demonstrated, with a prototype cost under $210 USD.
  • The system was evaluated for accuracy, cost, and ease of use.

Conclusions:

  • The proposed system enables accurate estimation of blood loss and fluid delivery for PPH.
  • This technology offers a valuable tool for healthcare providers, particularly in low-resource settings.
  • The innovation has the potential to significantly reduce maternal mortality associated with PPH.
