Intubations, especially in emergent settings, carry a high risk of hemodynamic instability with potentially catastrophic outcomes. Weight-based dosing of induction drugs can be inappropriately high for elective or emergent intubations and lead to hemodynamic instability. We hypothesized that monitoring the patient state index of SEDLine monitors (Masimo, Irvine, CA) would decrease the dose of induction drugs in the operating room during elective intubations.<i>Methods</i>. In this randomized study, SEDLine monitoring was provided to the intervention group but not to the control group during the induction of anesthesia in the operating room. Anesthesia providers in the intervention group were advised to titrate induction drugs to a Patient State Index of <50 before proceeding with intubation. The primary outcome was the induction dose of propofol and etomidate per kilogram normalized to propofol dose equivalents. Secondary outcomes included supplemental doses of ketamine, midazolam, fentanyl, phenylephrine, and ephedrine per kg, time from induction to intubation, administration of additional propofol or vasopressors after induction, mean arterial pressure <b>≥</b> or <65 mmHg, and lowest mean arterial pressure post-induction.<i>Results</i>. We found no significant difference in propofol equivalents between groups (<i>P</i> = .41). Using a SEDLine decreased the odds that a patient would require vasopressors during induction (odds ratio of .39 [95% confidence interval, .15-.98]).<i>Conclusion</i>. SEDLine monitoring during induction did not decrease dosing of the induction drugs etomidate and propofol but decreased the odds of receiving vasopressors.

The effects of positive pressure ventilation on right ventricular (RV) physiology can quickly lead to precipitous cardiovascular collapse, which increases the importance of maintaining adequate negative pressure ventilation strategies. Current strategies involve awake femoro-femoral cannulation with partial vs full flow femoro-femoral cardiopulmonary bypass (CPB), but both methods increase the risk of intraoperative blood loss due to systemic heparinization prior to sternotomy. In this case report, the authors describe an approach to anesthetizing a patient with severe right ventricular heart failure due to an intracardiac mass due to idiopathic HES.
