The hypothesis of this study is that a Ketamine / Propofol mixture will produce more stable hemodynamics as compared to Etomidate during emergent intubations in the intensive care unit. Patients that require a breathing tube to be placed in the ICU will be randomized to receIve either a Ketamine / Propofol mixture or Etomidate for sedation in order to place the breathing tube.
Endotracheal intubation is a procedure that may cause significant hemodynamic perturbations and can severely impact the outcome of the critically ill. To ensure a safe outcome during this particular procedure, there are many factors that the clinician is faced with. One decision that confronts the critical care physician involves the correct combination of medications with which to facilitate such a safe outcome. Given the reported hemodynamic stability, etomidate is a medication that is chosen by many providers in this particular situation. However, its association with a possible increase in mortality makes it less than ideal for a number of critical care physicians. In recent years, an admixture of propofol and ketamine has been studied that demonstrates hemodynamic stability based on the balancing of the hemodynamic effects of these two individual agents alone. This novel medication combination, sometimes referred to as "ketofol", may offer a valuable alternative to the critical care physician. Therefore, a randomized parallel-group clinical trial of adult critically ill patients admitted to a medical and/or surgical intensive care unit at Mayo Clinic Rochester who meet the criteria designated below for which urgent and/or emergent intubation is needed will receive one of two interventions based on stratified randomization. The "active" intervention arm will receive ketamine/propofol (ketofol) to facilitate endotracheal intubation. The comparison arm will receive etomidate. The primary outcome will focus on hemodynamic data recorded during the first 5 minutes post-administration with secondary outcomes looking at hemodynamic data at 10 and 15 minutes and addressing intensive care unit length of stay, mortality, adrenal function, and vasoactive medication use, among others.

Mean Arterial Pressure
Mean arterial pressure for the ketamine/propofol group at a 1:1 dose ratio compared to the etomidate group within the first 15 minutes post-administration in patients in need of urgent and/or emergent endotracheal intubation, as defined by any intubation within the intensive care unit excluding intubations for elective procedural events and codes.
Time frame: baseline and every 5 minutes up to 15 minutes minutes post study drug administration
Mortality
In-hospital/28 day mortality among patients in ketamine/propofol combination compared to in-hospital/28-day mortality in etomidate.
Time frame: Hospital Discharge or Day 28, whichever comes first
Vasopressor Use
The use of vasoactive medications to restore the blood pressure post-administration in the ketamine/propofol combination as compared to the etomidate group.
Time frame: up to 24 hours post study drug administration
Number of Participants With Adrenal Insufficiency
Incidence of adrenal insufficiency between ketamine/propofol admixture and etomidate. Adrenal insuffiency was evaluated with co-syntropin stimulation test.
Time frame: up to 24 hours post study drug administration

comparison of mechanical ventilation free days between the two groups
Time frame: hospital discharge or day 28, whichever comes first
Blood Product Transfusions
blood product transfusions \[Red Blood Cells vs. non-Red Blood Cells\] between the two groups
Time frame: hospital discharge or day 28, whichever comes first
