ciguatera
Ciguatera fish poisoning (CFP), also known as ciguatera, is a foodborne illness caused by eating reef fish contaminated with ciguatoxins.[4][2] Such individual fish are said to be ciguatoxic. Symptoms may include diarrhea, vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness, and weakness.[1][2] The onset of symptoms varies with the amount of toxin eaten. If a lot of toxins are consumed symptoms may appear within half an hour. If a low amount of toxins are consumed symptoms make take a few days to appear.[3] Diarrhea may last up to four days.[1] Symptoms may last a few weeks to a few months.[3] Heart problems such as slow heart rate and low blood pressure may occur.[2]

control severe bleeding adequate airway and ventilation continue external bleeding/internal transfer to definitive care w/blood an dIVF
140
confounding factors in shock
age/neonate/elder have decreased ability com compensate athletes have a resting HR of 40-50 so HR of shock could be 100-120 pregnancy increases blood volume by up to 50% so HR/CO incrase might mask shock until catagory 3-4 shock - placenta is the msot adversaely affected by vasoC so the fetus is at risk Rx like CaChB or BB may keep a person from developing the high HR signs to compensate for shock stees

SVR increases, ventilation from inital brath expands lungs PVR is 80% down post delivery
252
newborn closure of the PDA
starts to close soon after birth and finishes within 2 weeks
253
normal closure of the ductus arteriossu
lets blood from teh right ventricle enter the lungs - closure takes 2 weeks but increased PaO2 and loss of maternal prostaglandins post birth leads to initial closure
254
what happens in acyanotic congenital defects
increased pulmonary blood flow = pink babies - increased b flow to lungs demages lung tissue/vasculature leads to fibrosis then causes pulmonary HTN due to icnreased PVR. creased increased heart workload b/c heart muscle pumps against increased heart pressure more blood to lungs = pulmonary HTN and increased PVR
255
types of acynotic congential heart defects
pink babies = increased pulmonary blood flow PDA, ASD, VSD, pulmoanry valve stenosis, aortic valve stenosis, coarctation of aorta LEFT TO RIGHT SHUNT
256
Left to right shunt = congenital heart defect
acyanotic = increased blood flow
257
ductus arteriousus in utero
connects the aorta to the pulmonary artery - usually spontaneously closes at one year but functional closing soon after birth SO inability to functionally close is PDA. duct between aorta and pulmonary artery is open THUS some blood from the aorta flows back tot he poulmnary artery via the duct which causes extra poulmonary blodo flow increased pulmonary blood flow to lung = increased WOB and can lead to damage to the pulmonary artery over time from pulmnary vascualr disease and thick/stiff vasculature
258
acyanotic lesion
over circulation of the pulmonary vasculature so pulmonary vascular changes, fibrosis, pulmonary HTN
259
s/s of PDA
r/t to how big the PDA is in size. b/c that determines the amount of extra blood going to the pulmonary vascular
259

IVF if PDA
small b/c overstress heart if too large boluses (5-10 ml/hr)
262
management of HF
dieuretics and inotrophs to improve CO
263
Atrial Septal Defect
abnormal opening in the atrial septum size is r/t how much blood returns to the lungs - if large, 2-3x bloo drecirculates - enlarged R side of heart
264
CXR of Atrial Septal Defect
CXR often shows cardiomegaly w/increased pulmonary blood flow
265
long term effects of ATrial Septal Defect
enlarged R ventricle pulmnary vascular vascualr disease pulmonary HTN CHF dys
266
physiology of increased blood flow to the lung
increased work of breathing and can lead to damage to the pulmonary artery over time from pulmonary vascualr disease and thick/stiff vasulature
267
what is ventricular septal defect
holes in the ventricular septum - single or multiple holes multiple holes look like swiss cheese
268
when does VSD manifest
often manifest for first 2-4 wks of live b/c PVR still low but pas pulmonary vascular resistance fills the L-R shunting increse3s increased pulmonary blood flow leading pulmony HTN
269
surgery for VSD
banding pulmonary artery to decrease pulmary blood flow is a treatment while waiting for a final treatmetn decision - flow from left to r ventricle so recirculated into the lungs
270
interventions for VSD
small boluses inotropes diuretics' surgery
271
artrioventricular septal defect
mitral and tricuspid doesn't fully form so leave large opening
272
what does someone with arterioventricular septal defect look like
small stature and failure to thrive
273
what happens in artrioventricular septal defect
increased pulmonary blood flow b/c pulmonary vasculature is a low pressure system. so blood flows mroe easily and large open system leads to pulmnary HTN and pulmonary vascular disease. over time that causes CHF/
274
complication of artrioventricualr septal defect
echo sees the valve and can measure the puolmary artery pressure and degree of AV regurgitation
275
pulmonary valve stenosis
narrow valve between R ventricule and pulmonary - cause the heart to pump harder can't enough blood through teh narrowed valve - leadign to R ventricle hyeprtrophy b/c heat pumps aginst a restricted valve
276
using PGA for pulmonary valve stenosis
might use pga but short acting so the effects stop quickly after pump stops - need enough Rx to last teh trip and enough pump b - SE is apnea so have intubatin stuff
277
SE of PGA (for congenital heart defects)
apnea so have intubation stuff
278
what happens to the heart when the heart's workload increases
L ventricular hypertorphy with increased heart workload
279
physiology of coarctation of the aorta
blood is able to leave left ventricle fine but has hard time crossing the aorta obstruction - - if blood can't corss the obstruction the PDA is needed for systemci perfusion
280
congenital heart defect that needs PGE
severe coarctation of hte aorta - for systemic perfusion. if severe, you'd rely on PGE as PDA closes, try to g
281
BP changes low/high extremities congenital defect
