Surgery Flashcards
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
Dehissence
Not that bad. Failure of the fascia, wound not open but underneath fasciae planes not closed
Get a ventral hernia, see serosanguinous drainage that is salmon colored.
Diagnose-Clinical
Treat-prevent evisceration, use binders , reduce straining, and need to reoperate eventuall to close ventral hernia
Don’t need to fix right away
Evisceration
Failure of whole wound. Skin and fascia beneath break down and looks of bowel pop out.
Have person stand too early or strain too soon
Diagnose clinical
Treat surgical emergency yikes and apply warm saline dressings keep everything moist and never ever push it back in …then get to the OR
Fistula
Foreign body EPithelization Ttumour Irrigation/inflamed/inflammatory bowel (crohn) Distal obstruction
FETID
Treat-resect fistula may need to do a diversion
Prehepatic jaundice
Hemolysis and hematomas
Excess unconjugated indirect
INTRAhepatic jaundice
Genetic
Hepatitis
Mixed
Posthepatic jaundice
Obstruction
Gallstones
Cancer
Strictures
Increased conjugated
Gallstones
Dislodged in biliary tree choledectolithiasis
Mild dilation and inflammation of biliary tree and gallbladder
Expect to see increase temp and WBC and positive Murphy’s sign
Acute painful jaundice wiht inflammation
Diagnosis-RUQ US, MRCP bc can visualize with out ercp complication
Treat ercp or cholecystectomy
Stricturecancer
No inflammation bc not acute, no temp no WBC and no Murphy sign, no pain
Coursvier sign painless jaundice
Diagnose-RUQ US, MRCP
Treat-endoscopic US with biopsy, ERCP with biopsy may stent or resect dependent on underlying disease
Painless jaundice what do
Stricture or cancer
Bili20-26 (so single digits in gallstone)
Obstructive
Clay colored stool weight loss
Can’t get bilirubin into the stool
Cancer by saying in addition weight loss
Cancer
Obstructive
Distended gallbladder nonpainful
Obstructive
Work up obstructive jaundice weight loss clay colored stool, painless jaundice, distended non painful gallbladder
CT scan if +pancreatic mass its pancreatic cancer look for migratory thrombophlebitis
Diagnose pancreatic cancer with EUS with biopsy
Treat whipple remove parts of liver, pancreas duodenum
Positive CT with biliary tree with painless jaundice, weight loss, clay colored stool and distended gallbladder
Cholangiocarcinome
Diagnose-ERCP and biopsy
Treat resection
Negative CT with weight loss and clay stools, painless jaundice, distended gallbladder non painful
Ampulla of vater malignancy
-FOBT positive and negative colonoscopy
Diagnose-ERCP with biopsy can see malignancy
Treat resection
Obstructive jaundice stricture
Stenting and PSC
Gerd
Weakened LES, acid reflux retro sterna burn
Increased with flat and spices
Better sitting up and antiacids
Nocturnal asthma, gets up at night wheezing coughing acid comes up while laying on back
Diagnosis-no alarm symptoms with lifestyle and PPI
Avoid coffe peppermint chocolate and alcohol
Alarm symptoms or 4-6 week failure PPI lifestyle…EGD with biopsy
N/V, weight loss, anemia to biopsy first
If better lifestyle PPI continue treat this way. But Barrett’s metaplasia treat with high dose PPI anytime undergo metaplasia
Dysplasia now do ablation
Adenocarcinoma-resect
Nissen fundoplication-GERD surgery best test before this is 24 hr pH monitoring so want to do this before
If Ph low and symptoms consider nissen..but if too tight can creat achlasia
Achalasia
LES wont relax
Food gets stuck knot or call of food stuck at GE junction
Dysphasia-first fo barium swallow
See bird beak
But best test is monometry
Diagnosis -bird beek but next step is manometry
Before treat must do EDG with biopsy to rule out pseudo achlasia to rule out cancer
Treat-Botox temporary reserved for bad surgical candidates
- dilation but risk perforation if cant take surgery
- BEST WAY IS MYOTOMY remove muscle do too much get GERD
Upper third esophagus cancer
Squamous cellhot liquid, smoking
Lower third esophagus cancer
Adenocarcinoma
Related to gerd
Esophageal cancer
Dysphagia to large substances and smaller food and then water progressive dysphagia
1. Barium swallow ass asymmetric fungating mass
2,. Confirm endoscopy with biopsy
Always barium swallow first
Treat resection
Mallory Weiss tear
Superficial tear in mucosa in esophagus
Self limiting bleed
In someone vomiting as weekend warrior,
Diagnosis no-but treat like GI bleed, IV PPI call GI, CBC
Treat no
Boerhave
Trans mural tear esophageal perforation
Career vomiter
Bulemia or alcoholism
Air in mediastinum not contained crepitus in chest when breath hear and feel it
Hammands crunch from air around pericardium
Mediastinitis-fever, cough, septic
Diagnosis-1. Gastrograffin (bad for lung) swallow
2. If neg do barium swallow
3. If negative do endoscopy.
Stop when positive
Treat-surgical emergency to OR immediately
Small bowel obstruction
Adhesions if had surgery, hernia if not had surgery
Pt: positive flatus and bowel movements but then have obstipation with colicky abdominal pain with distant ion
Borborygmi->silent bowel sound
Gas and fluid proximal to obstruction and abdominal distinction.
DiagnoseL upright KUB look for air fluid levels follow that up with CT scan . If contrast material makes to rectum incomplete obstruction if non complete obstruction
- KUB then CT
Treat incomplete-contrast material reach rectum …conservative NG tube decomression IV fluids if no improvement surgery, if become peritoneal get emergent surgery
KUB must be upright look for air fluid levels
If complete-surgery
Hernia
Direct-adult, transversalis, i Guinean
Indirect-babies, inguinal ring, intestine in scrotum, inguinal
Femoral-female under inguinal ligament
Ventral-iatrogenic, failure of fascia to close, post op
Present as abdominal bulge-PE figure out what type.
Reducible hernia
Can push back in pops back out
In and out
Electively surgery
Incarcerated
Can’t reduce
SBO
Risk strangulation
Take care of it urgent surgery
Strangulated
Intestine dies, cuts off blood supply.
Peritoneal signs
Emergently to surgery
Appendicitis
Feaclith
Don’t need diagnostic steps bc clinical
Periumbilical pain go away and return at McBurney’s point , anorexia, N/V
CT scan-not needed for test but board service we like
Treat surgery
Carcinoid
Neuroendocrine tumor secretes serotonin only seen with Mets to liver to take effect
Liver and lung
Flushing, wheezing, diarrhea, heart R, fibrosisi
Diagnosis 5-HIAA
Treat CT scan and resect
Peritonitis
OR
Pancreatitis
Epigastric radiates through back
Positiona;, N/V
Lipase three times normal limit, amylase
Symptoms
Imaging CT US dont need it on day 1, but if person getting SICK hypotensive why r third spacing get CT scan bc worried about necrotizing fasciitis, WILL NEED NECROSECTOMY surgery after wait and conceal it dont go in too early ICU, do carbapenem antibiotics if FNA proven infection so need biopsy of necrotic tissue shows bug in order to give antibiotics so do FNA is nec p. OR 5 days to a week looks septic and ongoing fevers and leukocytosis might be abscess, so get CT scan and give antibiotics and tak them to surgery for IND, or early satiety weight loss and abdominal pain get CT scan might have pseudo cyst and size and time (<6 weeks and less 6 cm uncomplicated and watch and wait. If >6 weeks or greater 6 cm complicated high chance infection drainage how drain doesn’t matter. Just drain
CT scan good for complications of pancreatitis
NPO, Ivf, pain meds
Triglyceride panel
Chronic pancreatitis
Do not operate ! Pain-give pain meds, might need insulin and enzymes do not remove pancreas do not operate
Cholelithiasis
Mixed cholesterol
Fat female forty fertile
Pigmented-hemolysis
Present-colickyy RUQ pain radiates to shoulder worse with fatty foods
Figure out if have gallstones
Diagnosis-RUQ US see gallstones.
Treat-cholecystectomy elective when pt wants
-can use URODOXYCHOLIC ACID for old people not good surgical candidate
Cholecystitis
Gallstone pops out ends up in cystic duct
Have some inflammation ..proximal to stone inflamed
Gallbladder inflamed
Caused by gallstones in cystic duct see pericholecystic fluid, thickened gallbladder wall and gallstones
Present: constant RUQ pain with positive Murphy’s sign (if stop breathing bc of pain-arrest of inspiration)
Inflammation
Mild fever milld leukocytosis
Diagnosis-RUQ US look for thickened gallbladder wall and pericholcystic fluid …if not show what want get HIDA scan looking for perfusion after inject tracer if have will not fill up of gallbladder.
Treat-NPO, IV fluids, IV antibiotics and cholecystectomy URGENT have to be done 72-96 hours or will get hard and hard to get out…higher conversion to open and bad outcome
Cholecystostomy in non surgical candidate
Choledocolithiasis
Can get inflammation liver with increase AST ALT can get inflammation pancreas with increased lipase and amylase and bc liver continues to make bilirubin excreting conjugated so no where to go…..so first get dilation of duct and eventually bilirubin spill back over into blood and cause jaundice
Gallstones in common bile duct. May have hepatitis, pancreatitis, WILL HAVE JAUNDICE
Painful jaundice
May have Murphy sign
Have inflammation-mild fever and leukocytosis
Diagnosis-RUQ US for obstruction and see dilated ducts wont see an obstructing stone. If US negative get MRCP not HIDA
Treat-ERCP NPO give fluids and IV antibiotics, goal is ERCP
Can also go straight to cholecystectomy
ERCP urgent and then cholecystectomy electively
Flu-can see ball valve effect-stone move up and down get better then worse then better then worse
Cholangitis
Dilated ducts , gallstones in gallbladder and obstructing stone but have stagnant fluid and bacteria grow which ascends the biliary tree
Gallstone in common bile duct with infection usually with gut flora (gram negative rods and anaerobes)
RUQ abdominal pain, jaundice, and fever->charcots triad. If also have hypotension and altered mental status Reynolds pentad
Diagnosis-RUQ US see dilated ducts like in choledocolithiasis wont see stone but effects, then
Treat and diagnose-ERCP EMERGENT
Then can do cholecystectomy usually urgently
If spot want to jump to ercp but while get ready need IV fluid antibiotics and NPO
Antibiotics gallbladder
Cipro(gram neg) and metro(anaerobes)
Ampicillin-gentamicin (gam neg) and metronidazole(anaerobes)
WRONG IF PIP/TAZO bc expensive and covers both and covers gram positive like strep so over covering but done in hospital
Colon cancer diagnosis
Asymptomatic screening , postmenopausal man with iron defiency anemia, change in poop, bowel movement, and weight loss.
Catch with colonoscopy where see cancer (CT scan to stage and chemo radiation), FAP(thousands of polyps in young give colesectomy), polyp
Polyp
Good-small pedunculated, tubular
Bad-sessile no stalk, large and Villous
Look at polyp size a number and decide how soon should come back
- few-come back 5 years
- premalignant lesion-3 years
- a lot or dysplasia-come back every year
Ulcerative colitis
Superficial mucosa of colon
Patient bloody bowel movements rectal pain and weight loss
Get colonoscopy and see continuously inflamed rectum superficial inflammation on biopsy no skip lesions treated medically until 8 years then need colon cancer screening every year and get a prophylactic colectomy . If resect colon they are cured
Crowns disease
Not surgical unless fistula
Trans mural. Skip lesions can connect to other things
Fistula bc fecal soiling
Fistula diagnosis-fistula
Treat-fistulotomy
Better to use meds bc if remove another spot will pop up
Hemmorhoids
Internal -bleed dont hurt
External-hurt and itch but dont bleed
Diagnosis-visual inspection.
Anoscopy in internal hemorrhoids, just peek in through hole
Treat-surgical banding internal hemorrhoids and respecting external hemorrhoids. If remove too much can be left with a scar prevents ability to empty the rectum. BUT not gonna start with surgery start with sitz bath and preparation h
Anal fissure
Tight sphincter
Patient presents pain on delectation lasts for hours, so hold it in and get constipated and tears it even more
Diagnosis-see it
Treat-lateral internal sphincterotomy, nitroglycerin paste, sitz bath, then move to lateral internal sphincterotomy
Anal cancer
HPV=seamen causes squamous cell carcinoma
Patient-anoreceptive see especially men who have sex with men and HIV positive.
Screen with anal pap.
Diagnosis -use chemo and radiation. Usually works, nigro protocol
Pilonidal cyst
Abscess hair follicle
Congenital disease have to have a hairy butt
Diagnose-see
Treat-IND then OR to resect the cyst.
Somatic, visceral and neuropathic pain
Somatic-tissue pain prob with tissue , know where it is can point to it
Visceral pain- hijack the nerves above the skin of embryologist origin, referred…no pain receptors so what organs feel is stretch and obstruction
Neuropathic-damage to nerve, so thing it inner ages is bad and burning sensation pins and needles, nothing wrong. With the organ
Visceral pain forms
Obstructive0must be holoviscous some sort of peristalsis which comes up on obstruction and passes. Colicky in nature and since only in obstruction no fever and no leukocytosis. Think about diseases like cholelithiasis and nephrolithiasis
—no position will be comfortable writhe around
Inflammatory pain-pain becomes constant with fever and can be leukocytosis, person writhing around in agony and no comfortable position , organ is inflamed so think about cholecystitis and pyelonehpritis
Perforation-sick as shit, constant abdominal pain, motionless, moving will hurt, laying still, get an X RAY show free air have to do upright film think of cancer, penetrating trauma, or peptic ulcer dz
Ischemic pain-patient present with pain out of proportion they will be soft and writhing, touch belly soft but bowel is dying and becoming toxic or bloody bowel movement or sepsis think of ischemic injury, ppl with risk factors are CAD, afib and mesenteric ischemia ,
RUG
Lung, diaphragm, liver, gallbladder
LUQ
Lung, diaphragm, spleen,
RLQ
Kidney, ureter, appendix , ovaries and testes, colon
LLQ
Diverticulum, kidney, ureter, still have ovaries and testes
