Shoulder Dystocia,

Shoulder dystocia is an unpredictable, time-critical obstetric emergency requiring immediate recognition and rapid execution of established maneuvers. To date, there is no published evidence evaluating remote real-time support for the management of shoulder dystocia, which could be especially relevant for providers not frequently confronted with obstetric emergencies. This prospective, randomized, controlled, simulation-based trial compares healthcare providers' performance in managing a standardized shoulder dystocia scenario when supported by remote tele-assistance versus a standard cognitive aid. Teams of at least two healthcare providers manage a standardized scenario on the Laerdal MamaBirthie Task Trainer, with a trained study team member playing the laboring patient. Successful delivery requires completion of three predefined external maneuvers and one internal maneuver. Teams are randomized to Group A (cognitive aid: a standardized visual reference tool with written instructions and pictograms) or Group B (remote tele-support: live video guidance from a credentialed obstetric expert via Signal). The primary outcome is the total performance score (0-25 points). Secondary outcomes include cognitive load (NASA-TLX), usability (System Usability Scale), and subjective experience and communication quality (5-point Likert scales).

Prospective, multi-center, single arm with historical control, to verify the safety and effectiveness of the Yaari Extractor used by board certified or board eligible U.S. OB/GYN physicians in the management of shoulder dystocia.

Macrosomia is associated with increased risks for both the mother and the baby, including complications during delivery, injuries, and even death. The accurate diagnosis of macrosomia is often difficult before birth. There are a number of factors that can increase the risk of macrosomia, such as maternal obesity, diabetes, and excessive weight gain during pregnancy. There are also a number of different techniques that can be used to try to predict macrosomia, but none of them are perfect. The aim of this study is to evaluate sensitivity of measuring fetal clavicle length in third trimester compared with biacromial diameter and Hadlock formula IV for prediction of fetal macrosomia.
