Resolvi compartilhar através do youtube as aulas de ultrassom à beira do leito que eu dou para a residência de Brasília e do HCPA/HPS. Espero que gostem!

I decided to share on YouTube the bedside ultrasound classes I give to the residency program in Brasilia and at HCPA/HPS.

As probabilidades podem estar contra a gente… mas nós já vencemos elas cinco vezes e fomos campeões do mundo. Tá liberado acreditar na sexta. 🤞🇧🇷🍻

Nao existe nenhum trial comparando HAVL vs SGVL em doentes criticos....

@YukiKotani5 @takatoshikoroki @yoshirohayashi @kameda_icu I totally agree with you. I am biased on this discussion because we recently published this one: https://t.co/NRNf6jAOzM
We had the opportunity to do something similar, but we opted to use control as a placebo, e.g Fergusson 2022

@pfnery Pedro, você poderia explicar um pouco melhor seu ponto?

Should we be reaching for hyperangulated or standard geometry VL blades?

Much to my dismay, a systematic review with meta-analysis of 25 studies and 39k patients published this month found that hyperangulated blades had 4% lower first-pass success with higher risk of airway trauma. However, a few things worth noting before the HAVLs are taken behind the barn...
-The majority of the RCTs (n=16) were in the OR, not the ED or ICU
-Most of the RCTs were relatively small (<200 patients total) so they placed relatively low weight into the pooled outcome
-Unclear what to make of the signal of potentially higher risk of injury without a large RCT in the mixed ED/ICU population
-The large number of observational data included are obviously confounded by unmeasured effect modifiers (remember... no level of statistical slicing and dicing will ever provide the balance that an RCT will)

So, I do not think it's time to throw our hyperangulated blades in the trash, but thus far, the data does not support them being the amazing tool we initially thought they would be.
