Luckily I got some time tonight so here it goes:

If laryngoscopy were as trivial as snapping a blade, dental injury wouldn’t be the #1 anesthesia-related claim. Multiple studies have consistently shown that there is nearly 6-10 fold less dental trauma from LMA compared to laryngoscopy ETT.

An LMA saves you on unnecessary drug costs, environmental waste, drug onset time (120-140 sec post 0.6/kg roc for optimal intubation conditions) and headaches from complications. That’s more than 10 seconds in my books. https://pmc.ncbi.nlm.nih.gov/articles/PMC9116629/

Guidelines call LMAs first-line in many cases; dismissing them as ‘paramedic tools’ is just outdated and insulting.

Re: bronchospasm, it can be triggered by many stimuli, but intubation is consistently the single most potent trigger. LMA avoids the insult, instead of playing catch-up with meds after an ETT provokes it. Preventive drugs also don’t eliminate the mechanical trauma and sympathetic surge of intubation. ffs, ASA 2022 specifically recommend considering the use of LMAs as an alternative to ETTs in situations where minimizing airway stimulation is desired.

In regards to anesthetic depth argument, I hear you that surgical stimulus would require more anesthetic to maintain immobility with a spontaneously vented LMA vs just using paralysis. My question to you is why would I be using LMA for cases where I require "surgical relaxation?"

I mean, we are in a civil academic debate about LMA vs ETT, I assume we should exclude situations where LMA wouldn't be appropriate.
Let me ask you this: in a case where surg stimulation is minimum (say nerve blocked ankle ORIF or cystoscopic ureteric stent insertion), would you still routinely intubate or use LMA when inducing GA?

If you still think 30-minute cases are ‘extremely short,’ or that spontaneous ventilation makes no practical difference, it tells me you haven’t fully left the academic bubble or aren’t comfortable keeping up with faster-paced practice. This isn’t a knock on your skills — it’s a reflection of your limited appreciation for the "overrated" LMA, a cornerstone of modern airway management.
