The incidence of 12-month mortality and recurrent chest pain was higher in the lower ACh dose group (20 mu g). Conclusion: The learn more patients with MB significantly reacting at the low ACh dose had more pronounced baseline spasm, severe and diffuse long coronary artery
spasm, higher 12-month mortality and recurrent chest pain than those reacting with the higher ACh doses, suggesting that more intensive medical therapy will be required. Copyright (C) 2013 S. Karger AG, Basel”
“BACKGROUND: Recent studies suggest an increased risk of neurodevelopmental impairment following patent ductus arteriosus surgical ligation. The mechanisms are unclear, but intraoperative stress or pain may contribute. The objectives of this study were to determine if pain, evidenced by an increase in heart rate and blood pressure, during patent ductus arteriosus ligation would be accompanied by an increase in amplitude-integrated electroencephalogram (aEEG) voltage. METHODS: This was an observational, pilot study of infants born at 22.6-35.1 weeks with patent ductus AZD8055 cost arteriosus requiring surgical ligation. The aEEG was recorded
prior to, during surgery, and for 2 hours following surgery. Mean heart rate, blood pressure, and aEEG voltage were analyzed for each recording period. RESULTS: Seventeen preterm infants were studied at a mean postmenstrual age of 26.6 weeks. Following anesthetic induction, aEEG became suppressed and remained GDC-0994 ic50 suppressed during the postoperative period. Heart rate and blood pressure increased significantly intraoperatively. The aEEG voltage did not increase with an increase in heart rate. Infants received between 3.7-47 mu g/kg of fentanyl. CONCLUSIONS: There was no correlation between aEEG voltage and vital sign changes. aEEG is not a useful tool as a marker of pain during patent ductus arteriosus ligation, rather a more standardized approach to pain management should be considered.

“Background and Purpose-Microembolic signals (MESs)
are detectable within the transcranial Doppler frequency spectrum downstream from vascular atherothrombotic or cardiothrombotic lesions. A frequent occurrence of MESs has also been shown during bypass surgery or after mechanical valve implantation. We sought to compile the knowledge on MES prevalence, the clinical impact of these cardiogenic MESs, and microemboli composition.\n\nSummary of Review-We performed a systematic MEDLINE search and summarized the currently available literature about MESs during or after cardiosurgical procedures for this state-of-the-art report.\n\nConclusions-The nature of cardiogenic MESs is heterogeneous, and their prevalence is highly variable, reflecting their different origin from a broad spectrum of cardiosurgical conditions.
