Article Notes
It is important to note that the drivers of growth in Office Based Anesthesia are primarily economic and professional autonomy focused rather than patient care or quality of care. That is not to say these former priorities are in opposition to patient-centered goals, just that the patient is not the primary diver of this shift.
Low average volatile concentration shows some association with post-operative delirium in a sub-study analysis of cardiothoracic patients admitted post-operatively to ICU, although clinical implications are unclear. Use of BIS was not statistically significantly associated with a lower incidence of delirium, although there was a trend to lower incidence.
Of course the issue here is whether occlusion of the oesophageal entrance sufficient to prevent antegrade passage of a flexible silicon tube is a valid surrogate for the ability to prevent retrograde passage of liquid (ie. gastric fluid). There is a significant difference here and I feel this research adds little to the debate regarding benefit (or not) of cricoid pressure.
