The high ventilator pressure is causing Jaymun to have air bubbles in the skin around his neck. His fever broke yesterday for a while
and then returned a bit, but since he's been on broad spectrum antibiotics for almost 48 hours now, they have him on a temperature blanket
that automatically manages his temperature. Overnight they tried reducing the ventilator settings (gradually down to 70% oxygen and 45/11 pip/peep
and in the last 12 hours weaned his epinepherine/norepinepherine. His coagulation has been improving - enough to put in an ICP monitor.
ICP (intracranial pressure) was in the teens last night. Renal perfusion
was in the 70's.
This is all good ....if his ICP stays below 20 and his oxygen requirements keep reducing that means his body is healing. Prolonged mechanical ventilation at high pressures
can burst alveoli
. We want his lungs and brain to heal so we can aggressively wean the dexamethasone which irritates his bowels and progressively inhibits his immune system.
But an hour or two ago, his renal perfusion started falling, they started a slight amount of epinepherine again, moved his oxygen back up to 80.
10 minutes ago his ICP spiked to 45 held for a minute, then dropped to 28 and his nose started to bleed, and when they suctioned it he moved a little (low sedation?). His tummy is very large, and
there are no bowel sounds, he is constipated and although yesterday they allowed starting some supplemental feeds along with lactulose to soften
things up, because of the high ventilation settings his stomach fills with air and so we need to keep his stomach vented most of the time. So
whatever we put in his stomach eventually got suctioned out.
The really bad news is his ICP spiking which is now 55 again.
They added nitric oxide to his ventilation to dilate the vessels going from the heart to the lung.
That way they can decrease pulmonary hypertension, lower his Central Venous Pressure, reduce ventilator presure (made it to 45/10 so far),
and diminish the side-effects from that pressure (he has a small pneumothorax
and subcutaneous emphysema/crepitus
, and inflation of his stomach requiring a constant stomach vent)
He has metabolic alkalosis
which is slowly correcting itself.
His saline level was bolused to 159 and now maintained there with a drip (to pull water off the brain).
That is because his ICP (intracranial pressure) is trending
up and down from the teens to the 30's, with a slow rise (bad). They are talking about a ventricular device to drain
CSF but since his ICP is currently below 20 (where it should be) we are waiting to see.
Heart Rate: 121
Cystolic BP: 119
Ventilation (CO2): 35 (sick lungs means blood gases are probably higher)
Oxygen Saturation: 91 (ventilator 70% Oxygen pip/peep 45/10)
Temperature: (on cooling mat to regulate)
His face and tummy are swelling (edema). He has gas and solid stool in his intestines which the paralytic drugs are not helping to move.
A magic bullet (suppository) did nothing to help. His coagulation is still not normal (getting fresh frozen plasma) to improve that.
His ICP (intracranial pressure) has been at 12 for the last 5 minutes. That is good, but in the past two hours I've seen it as
high at 50+. I think the risk is for what they term ischemia/reperfusion injury
(where organs are starved for blood and then resupplied). His gut is not happy, very irritated. In fact,
since I now know that dexamethasone irritates the gut (has been studied to be a potential catalyst triggering sepsis by augmenting intestinal bacteria
in a weakened immune system) and also epinipherine (the ICU drug they used to trigger vasoconstriction to counteract "warm shock")
can damage the intestines by ischemia/reperfusion, I dug into my resource list and produced the following literature to the team here.
They are going to evaluate (we already have the ok for Green Tea ...it finally is in their med schedule Q4)
It helps I just happen to have a good supply at hand, from a quality US manufacturer.
Jaymun continues to be very sick. He has improved only a slight bit on the ventilator, and since he is sedated anyway, if he didn't have
brain swelling we could lower the ventilator just to the point where abnormally high CO2 levels would have been sedative. But that would cause
his brain to swell, and there is no room in his head for that. Merely suctioning his lungs causes his ICP to pop up into
the 50's. He is already at the highest level of sodium possible (159). There is very little room here for emergencies.
They might try an occilator instead of a ventilator
at some point.
And meanwhile dexamethasone is getting rid of his T-cells
dealing a huge setback to his immune system.
