Late postpartum eclampsia as an obstetric complication seen in the ED.

Preeclampsia is a complication of pregnancy associated with hypertension and proteinuria. Preeclampsia may be associated with grand mal seizures and is termed eclampsia. Historically, eclampsia occurring more than 48 hours after delivery, known as late postpartum eclampsia, was thought to be uncommon; however, recent evidence suggests that its incidence is increasing. In addition, the presentation of late postpartum preeclampsia-eclampsia may differ from that occurring during the pregnancy. This contributes to difficulty in diagnosing late postpartum preeclampsia-eclampsia in an emergency department setting. We report 2 cases of late postpartum eclampsia presenting 8 days after delivery, which highlight the unique features of this disorder and discuss some of the difficulties in managing these patients. Greater awareness and knowledge of this disorder by ED physicians should improve outcomes in these potentially life-threatening cases.

Effectiveness of a multidisciplinary quality improvement initiative in reducing door-to-balloon times in primary angioplasty.

Primary angioplasty (PA) for acute myocardial infarction (AMI) has emerged as the standard of care in hospitals with cardiac interventional facilities. The benefits from the PA are time dependent, but recent data raise concerns regarding the timeliness of delivery of care in AMI and the level of benefit achieved by current standards. We assessed the effectiveness of an extensive multidisciplinary quality improvement initiative in reducing door-to-balloon (DTB) times in PA. The PA process was divided into six separate time periods, which were assessed individually. Subsequent quality initiatives resulted in a dramatic reduction in the mean DTB time (141.3 minutes preintervention compared to 95.1 minutes postintervention; P < 0.001).

Value of a single troponin T at the time of presentation as compared to serial CK-MB determinations in patients with suspected myocardial ischemia.

BACKGROUND: Prior studies with cardiac markers have focused predominantly on subjects presenting to the emergency department with chest pain or unstable angina, and have relied on serial markers for the diagnosis of acute myocardial infarction. We evaluated the diagnostic utility of a single cardiac troponin T (cTnT) determination at the time of presentation as compared to serial creatine kinase (CK) MB determinations in a broad spectrum of patients with suspected myocardial ischemia. METHODS: A total of 267 consecutive patients presenting to the emergency department with suspected myocardial ischemia had a single, blinded cTnT determination drawn at the time of presentation to the emergency department in addition to routine serial electrocardiographic and CK-MB determinations. RESULTS: The specificity (93.7% vs. 87.1%; p<0.05) and positive predictive value (80.0% vs. 69.4%; p<0.05) of a single cTnT determination were superior to that of serial CK-MB determinations without compromising sensitivity. Forty-six percent of patients with confirmed myocardial infarction and an abnormal cTnT at presentation had a normal initial CK-MB determination. Conversely, 20% of patients without acute coronary syndromes had an abnormal CK-MB determination in the setting of a normal cTnT. The initial cTnT was abnormal in all patients with confirmed myocardial infarction and a symptom duration of at least 3.5 h. CONCLUSIONS: In a heterogeneous population of patients with suspected myocardial ischemia, the initial cTnT determination drawn at the time of presentation is a powerful diagnostic tool that, when used in context with symptom duration, allows for more rapid and accurate triage of patients than serial CK-MB determinations.
