一種新型工具可以預測肩先露難產，這種情況發生在嬰兒頭已經分娩出來但是肩膀仍然卡在產道之內。

在頭部分娩出來之后，陰道分娩胎兒的難度增加，特別是當肩膀的大小和位置不佳的時候，在醫學上是一種急癥。臍帶被壓縮，減少了胎兒的氧氣供應。除此之外，產科醫師或許會使用一系列危險的方法，可能會牽拉或者損傷連接胳膊的神經。與嚴重肩先露難產相關的新生兒損傷包括：臂叢神經損傷，鎖骨骨折，以及非常罕見的大腦損傷或者死亡。檢測率較低或者假陽性率較高，導致了目前的檢查效果并不能夠令人滿意。

這種新型CALM (computer-assisted labor management，計算機輔助分娩控制)肩先露篩查是以能夠提高預測成功率改進檢查結果的軟件為基礎的。這套系統是由LMS醫療系統(Montreal, Canada)研制開發的。

LMS公司首席醫療官和創始人Emily Hamilton說：“我們公司的新型預測模型，能夠改進早期預測和假陽性率，從而增加了嚴重生殖并發癥患者獲得良好預后的機會以及患者的安全性。使用CALM肩先露篩查系統，醫療保健團隊能夠獲得經驗性的信息，可以制定干預措施、設計臨床方案，給妊娠婦女和臨床醫生提供有價值的選擇?！?/P>

LMS計算機輔助分娩控制產品為醫生和護理人員提供了創新性的產科決策支持和風險控制工具，能夠與各種臨床信息系統整合，設計用于改善預后并提高分娩婦女和嬰兒在分娩過程中的安全。

Tool for Predicting Shoulder Dystocia
 
A new tool predicts shoulder dystocia, which happens when a baby’s head has been born but the shoulders are still trapped in the birth canal.

The difficulty of delivering a baby vaginally can increase after the head is born, particularly when the size and position of the shoulders are unfavorable, creating a true emergency. The umbilical cord can become compressed, reducing the amount of oxygen supplied to the baby. In addition, the obstetrician may have to use a series of risky maneuvers that may stretch or injure the nerves leading to the arm. Neonatal injuries associated with severe shoulder dystocia can include brachial plexus injury, clavicular fracture, and, very rarely, brain damage or death. Low detection rates or unduly high false-positive rates have made current detection methods unsatisfactory.

The new CALM (computer-assisted labor management) Shoulder Screen is based on software that improves prediction and results in better outcomes. The system was developed by LMS Medical Systems (Montreal, Canada).

“Our new predictive model has the capacity to improve both early prediction and false-positive rates, resulting in an opportunity to improve outcomes and patient safety from this serious birth complication,” stated Dr. Emily Hamilton, chief medical officer and founder of LMS. “With CALM Shoulder Screen, healthcare teams will have empirical information upon which to base policies of intervention, design clinical protocols, and empower women and clinicians to make informed choices.”

The LMS Computer-Assisted Labor Management parent product provides doctors and nursing staff with innovative obstetrical decision-support and risk-management tools integrated into robust clinical information systems designed to improve outcomes and patient care for mothers and their infants during delivery.
