Absoulte contrindications to surgery
diabetic coma and DKA
Other contraindications to surgery
poor nutrition -
------albumin < 3,,
------transferrin < 200
------weight loss of total body < 20%
Lever failure - High bili, Pt > 16 ammonia > 150
SMoker - stop 6-8 wks prior
Meds to stop prior to surgery
aspirin
NSAIDS
vit E ( 2 weeks)
If have CKD what do you do 24 hrs proior to surgery
diayllsis 24 hours prior
What post surgical complication would you worry about with the BUN > 100
Platlet dysfunction and bleeding
What would the labs show for uremia induced platlet dysfunction
Normal platlets but prolonged bleeding time
SIMV
You get a set TV. therfore if the patient starts the breath they get the full volume
PVRC
Pt determines the rate but a boost of pressure is given for each breath
CPAP
Pt must breath on their own but prssure is given all the time
PEEP
- pressure delivered at the end of the cycle to help th avelooi open VERY important top help in ARDS
What would you change on a vent if : PaCO2 is Hihg and pH is low
increase Rate or TV
What would you change on a vent if : Paco2 is low and Ph is high
decrease rate OR TV
IF Hco2 is low and pCO2 is low
what is the cuase and what do you check next
Metabolic acidosis
next check anion gap - ( Na- [cl+ hco3])
Causes of metabolic acidosis With a HIgh anion gap
M-methanol
U- uremia
D- DKA
P-propylene gylcol
I-iron, isoniazid
-L - lactic acidosis
E- etholnol
S- Siacylic acid
Causes of metabolic acidosis With a normall anion gap
diarrhea, diuretics RTA I< II, IV
If HCO3 is high and PCO2 is high and cl- in the urine is < 20
Vomiting/NG tube antacids, diuretics
If HCO3 is high and PCO2 is high and cl- in the urine is > 20
Conns Bartters Gittlemans
then you have low sodium when do you use 3% Na iv
when the patient is symptomatic with seizures or sodium is below 110
complication of correctio of hyponatermia too quickly
Centeral pontine myoliinolysis
If you ahve an increase in total body sodium what do you replace with and what is a complication
replace with D5 or hypoteonic fluid
risk of cerebral brain edema
Numbness chvostek, or troussaeus sign or Prolonged Qt interval
Decrease Ca2+
Bone pain, kidney stones, Abdominal discomfort from constipation, Depression anexity trouble sleeping anorexiaOR shortened QT
Increased Ca2+
Paraylsis, Ileus, ST depression U waves
Cause and Treatment ?
Cause decrease K and treatment Give K max 40 mEq/hr
Peaked T waves ( generalized) prolonged PR and QRS waves
Cause?
Treatment?
Cause - give Ca gluconate then insulin + glucose and kayexalate albuterol and sodium bicarb..... last resort is diaylsis
Maintenacne IVF equation
$: 2;1
0-10 kg - 4ml/kg/hr
10-20 - 2 ml/kg/hr
all above 20kg: 1ml/kg/hr
Complication of TPN
Acalculus cholecystitis hyperglycemia liver dysfuxn, zinc def. lyte prob
If someone hasa circumferential burn
consider escharotmy
If someone has signed nose hairs wheezing and soot in mouth
Bad intubation - low threshold
Patient with confusion and cherry red skin
CO - best test is carboxy hb - DONT use pulse Ox
HYPER-Clotting. In the elderly
CAcner especiially pancreatic
Hyper- Clotting and Edema Htn and foamy pee
nephrotic syndrom
HYPER- Clotting in a young person with a + Family hx
factor V leiden
If you have AtIII def what medicatio will not work on the clots
heparin
HYper- clotting and a young women with a PMH of spontenous abortions
Lupus anticoagulant
Post Op HYper Clotting decrease in Plt
HIT - if heparin was given w/in 5-14 days
How do you treat HIT
leparudin and agatroban
Bleeding problem with an isolated decrease in Pltss
ITP
Normal PLts but increase in bleeding time and Ptt
von willibrands disease
Low Plts, Increase PT, PTT BT Low Fibrinogen, high D dimer and schistocytes
DIC!!! caused by Gram - sepsis carcinomatosis and OB stuff.
RULE of 9 for burns Adults Vs children
Adults- 9 for each Arm, 9 for the head, 18 front, 18 back, 1 genitals, 18 for each leg
Babies- 18 for the head, 0 for each arm, 18 front and 18 back and 1 genitals and 14 legs
Parkland forumla adults and babies
and how fast do you give the voluem
adults : KG %BSA 3-4
Kids : Kg %BSA 2-4
- this gives you a value in Ml and you give 1/2 over the 1st 8 hrs and rest over the next 16hrs
How do you abx to Burn patients
TOPICAL !!!!
Silver sulfadiazine
Doesnt penetrate eschar and can cause leukopenia
Mafenide
Penetrates eschar but hurts like helpp
silver nitrate
Doesnt penetrate Eschar and causes hypoK and HypoNa
Chemical burn 1st step
irrigate > 30 min
Electrical burn
1st test and then amangement
1st test: Get and EKG to check for arrthymias
managment: check for myogliobinuria and ATN
Check K levels from cell lysis
Monitor limb temperature for compartment syndrome
- criteria - 5 P and pressure > 30mmhg
When a smoker is coming out of anesthetics do you want to keep their pulse ox at 100
No because smokers and Co2 retainers need the low oxygen for the respiratory drive
Goldmans risk what is the MOST important Risk
CHF- check EF < 35% NO SURGERY for you
Goldmans risk what is the Second MOST important Risk
MI w/in 6 mon
EKG-> stress test--> cardiac cath --> revasc.
Metformin important prior to surgery
YOU must stop because of lactitic acidosis
What is more effective for your patient to increase Rate or Volume ?
By increasing rate you are not increasing the amount of I2 to the aveoli
by increasing TV you are increasing the effective oxygenation
Low sodium but signs of fluid retention
CHF, nephrotic cirrotic
DEcrease volume and decrease sodium
diureticcs or vomiting and free water
NOrmal volume but decrease in NA
SIADH ! addisons and hypothyroidism
When do you use hypotonic saline 5%
patient is symptomatic with seizures or sodium less then 110
Maintenacne IVF for daily requirments
up to 10Kg - 100ml/kg/day
NExt 10 -> 50ml/kg/day
All above 20 -> 20ml/kg/day
1st degree burn what layer of skin
epidermis
Why dont you give IV or PO antibiotics to a burn victom
it breeds resisitance
If yo have low sodium what do you want to check
the serum osmolarity because high glucose makes the plasma look too dilute
What kills you in rhado!
The hyperkalemia
Patient is unconscious
INTUBATE
If a guy is stabbed in the neck and there is subcutenous stridor then what to do
Use fibrooptic broncoscope to secure the airway

If patient was inward mvmt of the right ribcage upon inspiration
FAIL chest > 3 consec rib fractures
Fail chest treatment
o2 and pain control ( NERVE BLOCK) - do not give morphine because it decreases repiratory drive

A patient dies suddenly dies after a centeral line
AIR embolism
Causes of air embolism
lung trauma ( too much TV) , vent use, during heart vessel surgery
