In this issue of Obstetrical Anesthesia Digest we feature two manuscripts. The first manuscript is titled; "National Patnership for Maternal Safety Recommended Maternal Early Warning Criteria Are Associated with Maternal Morbidity" written by D.E. Arnolds, A. Smith, J.M. Banayan, R. Holt, and B.M. Scavone. It was recently published in the December 2019 issue of Anesthesia and Analgesia. This study looked at the utility of the maternal early warning criteria (MEWC) as a screeing tool for adverse maternal events. The MEWC were created by the National Patnership for Maternal Safety to identify pregnant women at risk for morbidity and mortality. Screening tools prioritize sensitivity over specificity, and the MEWC have been found to have excellent sensitivity and negative predictive value. The clinical utility of the MEWC are discussed in this article.
        The second manuscript evaluates the common use of tranexamic acid (TXA) in the obstetrical population for which it has been beneficial for obstetrical hemmorage, and reviews drug errors that have occured with its use. Most os these horrible mishaps appear due to system and human factors after thorough review in this article. It was written by S. Patel, B. Robertson, I. McConachie and is titled "Catastrophic Drug Errors Involving Tranexamic Acid Administered During Spinal Anesthesia" in the July 2019 issue of Anaesthesia, which is endorsed by the 2019 Association of Anaesthetists. This article is the analysis of 20 global cases of accidental intrathecal injection of TXA and the devastating resultant 10 deaths out of the 20. The non-fatal cases resulted in severe neurological and cardiac complications, requiring resuscitation and/or intensive care and permanent patient injury
