Summary
In-utero transfers are crucial for neonatal care but often face organizational delays and failures. A centralized planning service could improve efficiency and outcomes for these critical neonatal transports.
Area of Science:
- Neonatal care
- Maternal-fetal medicine
- Healthcare logistics
Background:
- Perinatal transfer is a critical component of neonatal care.
- In-utero transfer is preferred over postnatal transfer when feasible.
Purpose of the Study:
- Quantify the prevalence of in-utero transfers.
- Determine the time expenditure in arranging these transfers.
- Identify failures in the organization of potential in-utero transfers.
Main Methods:
- Prospective study of referred and completed in-utero transfers.
- Questionnaire study of failed potential in-utero transfers.
- Analysis of data from London Ambulance Service (LAS) and Emergency Bed Service (EBS) over six months in 2009.
Main Results:
- 438 in-utero transfers were undertaken by LAS; 180 (53%) of 338 referrals to EBS were successful.
- 11 of 69 emergency postnatal transfers of preterm infants (<29 weeks) were classified as failed in-utero transfers.
- Median time for EBS involvement was 340 minutes; arranging failed transfers involved contacting a median of 7 units and took 240 minutes.
Conclusions:
- Arranging in-utero transfers is time-intensive.
- A significant number of in-utero transfer attempts fail due to non-clinical reasons.
- A centralized in-utero transfer planning service could save clinical time and potentially improve neonatal outcomes.

In Vitro Fertilization
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

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...
