  • The Effect of Nitrous Oxide on Laryngeal Mask Cuff Pressure While cuff pressures have been shown to increase during general anesthesia with the laryngeal mask airway, the extent of the pressure rise has not been systematically studied for procedures lasting more than 2 hours. This descriptive clinical study demonstrated that there was a gradual increase in the cuff pressure well over a 3-hour period during nitrous oxide and oxygen anesthesia.
    Keywords: Cuff pressure, laryngeal mask airway, nitrous oxide.

  • Anesthetic Implications of Subacute Left Ventricular Rupture Following Acute Myocardial Infarction: A Case Report Rupture of the free wall of the left ventricle is associated with a high mortality rate. This article reports a case of subacute rupture of the left ventricle that was successfully repaired using a novel surgical technique and discusses the anesthetic implications surrounding the case.
    Keywords: Cardiovascular anesthesia, cardiac tamponade, myocardial infarction, ventricular rupture.

  • Newer Trends in Monitoring: The Esophageal Doppler Monitor This review compares the esophageal Doppler monitor with the pulmonary artery catheter and examines the monitor's history; pediatric, perioperative, and intensive care unit uses; and costs and practical issues.
    Keywords: Esophageal Doppler, hemodynamics, monitoring, ultrasound.

  • The Dose-related Effects of Bolus Esmolol on Heart Rate and Blood Pressure Following Laryngoscopy and Intubation While many researchers have studied the effects of esmolol on heart rate and blood pressure, all studied relatively large doses of esmolol. This study shows that small doses of esmolol may block the increases in heart rate and blood pressure resulting from laryngoscopy and intubation.
    Keywords: Blood pressure, esmolol, heart rate, laryngoscopy.

  • Acute Circulatory and Respiratory Collapse in Obstetrical Patients: A Case Report and Review of the Literature This report describes acute cardiorespiratory collapse in a young woman during cesarean delivery of a healthy infant. The differential diagnosis, medical assessment, treatment, prevention, and anesthetic implications for gravid women with unexpected cardiorespiratory collapse are discussed.
    Keywords: Amniotic fluid embolism, pregnancy, thromboembolism, venous air embolism.

  • A Comparison of Nurse Anesthesia Practice Types The red blood cell is multifunctional entity whose absence would make life as we know it impossible. This Journal course reviews the architecture of the red blood cell, the biochemistry of hemoglobin, the mechanics of the oxygen-hemoglobin affinity-altering diphosphoglycerate compounds, and the variants of hemoglobin.
    Keywords: Blood chemistry, hemoglobin, 2,3-diphosphoglycerate.
