Surgery Flashcards
(188 cards)
Prep evaluation (not for emergent) heart
Decompensater HF with EF <35%——if volume overload 75% die
MI-best to wait 6 months __if wait 4 months 40% die, 66 die 6% months
No surgery unless to fix heart problem
Goldman Index-higher bad…most points for JVD(EF<35%), recent MI
DX-do an EKG, echo, stress/LHC
Treat-MI=stent/CABG wait 6 month a revaluate
CHF-BB and ACE-I, volume overload diuress with loop diuretics
Pre op evaluation lungs
Ventilation more important than oxygenation
Can always Turn up oxygen but if bad lunches cant get rid of CO@ worsen acidosis, acid base status deranges
Pt-smoker, COPD, asthma, interstitial lung disease (DPLD)
Do-PFT, and day of maybe ABG look for increased CO2 or decreased O2
To-give oxygen for low oxygen, inhalers, STOP SMOKING (increas bronchial secretions immediately after…so need to stop smoking 8 week before and use nicotine patch)
Pre op evaluation liver
MELD score
Childs-pugh (a good, c dead)
Pt-albumin down, clotting factors absent PT/PTT up, total bilirubin elevated, ascites, encephalopathy
-if any of these have 40% of death, if all 5 100% death and no treatment other than transplant
Nutrition
Important for healing
Pt:thoselose 20% BW, albumin<3, skin anergy
Diagnose:prealbumin and CRP,
If albumin low, prealbumin low and CRP up no protein
If albumin low and prealbumin ok and CRP albumin liver problem
Fail skin anergy-cant go to surgery wont heal
Treat-oral>IV, give ten days of replacement>5 days
Metabolic preop evaluation
DKA=high blood sugar
NO surgery if DKA-IV fluids and IV insulin
If blood sugar out of control give insulin
CABG stent ok if bad
Yes emergent
Post op fever
Wind Water Walking Wound Wonder drugs
Fever during surgery
Malignant hyperthermia (wonder drugs) Anesthesia
Treat with O2, dantrolene and cool them off
Ask if had personal or family history to anesthesia bad reaction
Fever right after surgery
Bacteremia (surgeon prob)
Diagnose with blood culture
Treat broad spectrum antibiotics-vancomycin
Prophylaxis-maintain sterile field and be careful in gut and dont poke the bowel
Post op day 1 fever
Atelectasis
Diagnosis chest x ray to make sure no consolidation pneumonia
Treat-no treat
Prophylaxis ICS and out of bed , get them to move and breathe
Post op fever day 2
Pneumonia
Diagnose-chest x ray consolidation
Treat-broad spectrum antibiotics 0vancomymic
Prophylaxis-ICS and out of bed
Post op day 3
UTI
Diagnose UA urine culture-if cast pyelonephirits and prob had before surgery
Treat abx
Prophylaxis -foley taken out
Post op fever day 5
DVT/PE especially orthopedic
-2 cm bigger one leg, Pe hypoxia hypercapnia resp alkalosis
Diagnose-US bl lower extremitt
Treat heparin to warfarin bridge to prevent hypercoagulability
Prophylaxis-up and walking around and give low molecular weight heparin, usually give it after surgery
Post op day 7
Would cellulitis
Diagnose-US negative fo abscess
Treat antibiotics
Prevent keep sterile field and keep clean post op
Fever day 10-17
Abscess
Diagnose US positive for abscess or use CT
Treat antibiotics, back to OR for IND
Prophylaxis keep wound clean
Post op chest pain
MI, PE, or something else.
Get EKG and troponins for MI
Get US LE or spiral CT scan for P
If MI post op
PCI if stemi
Heparin if troponins are elevated NSTEMI
If PE post op
Heparin bridge to warfarin
Altered mental status post op
Electrolytes issue(NA, Ca)-get BMP
Sundowning-older people-atypical antipsychotics , reorient them
Hypoxemia-PE, pneumonia, ARDS(have to have prolonged intubation, transfusions, and intubations-will need PEEP),
DT-HTN, tachycardia post op pain meds dont work, sweaty and shake, can prevent seizures 48-72hrs on way to seizures. Give benzos.
Decreased urinary output post op
Normal is 0.5cc/kg/hour
If less bad
Urge? If yes have obstruction can evaluate with bladder scan or in and out cath
No urge? Nothing in bladder might be renal failure . Look at urinary output….any at all? Non!-mechanical probably kinked foley…unkink foley or irrigate it-if some output! Give 500cc bolus challenge and if increase urinary output they were volume down and give them more fluid. If dont though intrinsic renal disease and had some big hit or allergic reactions to get this.
Abdominal distinction post op
Ileus, obstruction, oliguria
Ileus
Functional day 1,2 no stool no fart
Get KUB flat and erect
See small bowel and large bowel dilated at same time
Treatment-fluids, K, and getting them to move
Obstruction
Obstruction
Person suspect has ileus but day 5 still no stool and no gas
Diagnose -upright erect KUB
If obstructed nothing gets by and see entire bowel decompressed in SBO, if LBO large bowel decompress and proximal distended and small bowel normal.
Treat-NG tube and surgery to undo damage0usually adhesions
Ogilvie syndrome
Functional but only impacts colon and elderly
Diagnose flat erect KUB
Small bowel normal large bowel distended but no distal area that’s good. Whole thing is big
Treat decompression with rectal tube , stigmine, may need colonoscopy to rule out cancer
