Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Summary
This summary is machine-generated.

Acute peripartum anemia in monochorionic twins, often linked to twin-to-twin transfusion syndrome (TTTS), poses significant risks. Prompt recognition and management are crucial due to potential for severe fetal complications like anemia and brain infarction.

Area of Science:

  • Perinatology
  • Maternal-Fetal Medicine
  • Neonatology

Background:

  • Monochorionic twin pregnancies face unique challenges, including twin-to-twin transfusion syndrome (TTTS).
  • Acute peripartum anemia is a rare but serious complication requiring immediate attention.

Observation:

  • A case of probable acute TTTS with acute intrapartum fetoplacental transfusion (AIFT) in a monochorionic monoamnionic pregnancy is presented.
  • The first twin exhibited severe anemia, hypovolemic shock, seizures, and a parieto-occipital infarction post-birth.
  • The second twin was plethoric but clinically stable.

Findings:

  • Absence of typical ultrasound markers for chronic TTTS.
  • Demonstration of a potentially catastrophic acute fetoplacental transfusion event.
  • Correlation between acute anemia and neurological damage in the affected neonate.

Implications:

  • Highlights the unpredictable nature of acute TTTS and AIFT in monochorionic twins.
  • Emphasizes the need for heightened awareness and preparedness during delivery planning.
  • Underscores the potential for severe, life-threatening outcomes for affected twins.
