UDLCO PaJR CBBLE team based learning:
[17/07, 08:50] moderator: What do you mean power couldn't be elicited? Wasn't he moving his limbs even in his altered sensorium state?
Also what do you write in CNS examination for altered sensorium? Hmf couldn't be elicited?
[17/07, 08:46] : Where's the ABG on 27/6/24 in this chart? Why not included that? How do you explain the presence of metabolic acidosis, respiratory alkalosis and metabolic alkalosis in it? Have you checked the delta gap?
[17/07, 08:48] : What do you mean power couldn't be elicited? Wasn't he moving his limbs even in his altered sensorium state?
Also what do you write in CNS examination for altered sensorium? Hmf couldn't be elicited?
[17/07, 08:49]: How did we gain by testing the urinary electrolytes?
[17/07, 09:06] : Sir Can't it be Respiratory alkalosis due to Increased RR & Compensated by Metabolic Acidosis?
[17/07, 09:07] : I mean We can't Elicit for Power with Resistance Sir
[17/07, 09:14] moderator: Is the metabolic acidosis compensation adequate? If not why? What generally happens in similar respiratory alkalosis patients?
[17/07, 09:15] moderator: But at least against gravity power was noted?
[17/07, 09:36]: For every Drop in Pco2 by 10 Hco3 drops by 2 in Acute & 4 in Chronic Sir ......But here Bicarb drop is More Sir
[17/07, 09:37]: Change in Anion Gap is 17 Sir & Change in Bicarb is 19 Sir
[17/07, 09:38] : Indicating the presence of Normal AG Metabolic Acidosis Sir
17/07, 09:40] moderator: How do we explain that?
[17/07, 09:39] : Yes Sir ....He was able to move against gravity
[17/07, 09:40] moderator: So automatically in your assessment you can document grade 3 power was at least present?
[17/07, 11:02] Rakesh Biswas: [17/07, 09:40] moderator: How do we explain that?
[17/07, 09:43] : Can't we explain that with Diarrhoea he had Sir ??
[17/07, 09:45] : Or there can be chance of RTA /Adrenal Insufficiency also Sir ??
[17/07, 10:07] moderator: Review the ABG diarrhoea thesis from narketpally here ๐
https://2018-21batchpgy3gmpracticals.blogspot.com/2021/08/18100006004-thesis.html?m=1
And let me know if your patient's sequence of events has been described in all the patients of diarrhoea logged in the 2019-21 thesis.
[17/07, 10:10]t: I guess we had another thesis on bicarb supplementation on acidosis as well
[17/07, 10:24] CBBLE: Yes can find it here๐
