Complicated third stage of labor: time to switch on the scanner.

This Editorial chronicles the current experience in ultrasound usage during pathologic events occurring in the third stage of labor. Further improvement in the technology for carrying out clinical research will improve our knowledge so that more information can be gleaned from this modality to bestow optimal management for such potentially dangerous conditions. Awareness of the capabilities of sonography may provide the motivation for its use, and obstetricians are encouraged to scan the third stage of normal deliveries for better recognition of normal findings and improved assessment of abnormal ones. Although final decisions should be based mainly upon sound clinical judgement, we contend that complicated third stage of labor warrants turning on the scanner.
