Summary
This review highlights inconsistencies in defining and managing abnormal amniotic fluid volumes (AFVs). New algorithms are proposed to guide clinical practice for oligohydramnios and polyhydramnios.
Area of Science:
- Maternal-Fetal Medicine
- Obstetrics
- Diagnostic Ultrasound
Background:
- Amniotic fluid volume (AFV) assessment is crucial in prenatal care.
- Current definitions and management of abnormal AFVs lack universal consensus.
Purpose of the Study:
- To review evidence defining normal and abnormal AFVs.
- To evaluate current management recommendations for AFV abnormalities.
Main Methods:
- Evaluation of studies establishing normal AFVs.
- Analysis of ultrasound estimation methods for AFVs.
- Review of national and international guideline recommendations.
Main Results:
- A timeline of AFV threshold development was created.
- Significant variation exists in definitions and management of abnormal AFVs across 13 guidelines.
- An algorithm for managing oligohydramnios and polyhydramnios was developed.
Conclusions:
- AFV assessment is a frequent procedure in antenatal care.
- Discrepancies in current guidelines necessitate standardized approaches.
- Proposed algorithms aim to aid management of abnormal AFVs pending further research.

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.
