[2025-10-01T12:18:10.861575] [PI reasoning] **Researching placenta previa management**

I need to clarify the best regimen for managing placenta previa, particularly the Macafee and Johnson regime. It’s recognized for expectant management, which involves hospitalization, sedation, and keeping the patient on bed rest until the fetus is mature. The answer seems to point toward the Macafee regimen as the solution! I’ll also want to find some articles that discuss expectant management of placenta previa for evidence, particularly those referencing McAfee and Johnson. Let's search for that information.

I want to ensure that I find the correct regimen for managing placenta previa, specifically the one by "Macafee and Johnson." So, I'll search again, using the term "McAfee and Johnson regimen" to find more supporting evidence about it. I need to confirm the details accurately for the user and make sure I provide the right information. Let's keep digging!
