General Ward Management

• Electrolyte imbalance• Post Op Fever• Chest pain & SOB• ECG analysis• Post-op cardiac complications

Hypokalemia

• What is the cause?– Loss through GI tract (diarrhea,vomiting)– Diuretics (lasix)– Metabolic / Respiratory Alkalosis– Hyperaldosteronism– Diabetic ketoacidosis (with osmotic

diuresis)– Other renal losses - RTA

Hypokalemia• ECG (PAC, PVC, flat Ts, U waves, ST depression)• Replenish Potassium:

– IV: • Add 20-40mEq KCl/L to IV solution• 10 mEq in 100cc H2O (x 3) ~> each over 1 hr• hurts, remember KCl scleroses veins

– Oral:• KCl elixir 20 mmol/15ml• K-lyte 25mmol/packet• i-ii Slow K tabs (8mmol)

– Replace Mg if deficient

• Repeat lytes

HyperkalemiaWhat is the causes?• Pseudohyperkalemia:

– Hemolysis• Excessive Intake:

– K+ supplements (oral or IV), Blood transfusions• Decreased Excretion:

– Renal failure (acute or chronic)• Drugs:

– K+ sparing diuretics (spironolactone)– ACE inhibitors– NSAIDS– Trimetoprim / sulfamethoxazole (TMP/SMX)– Cyclosporine– Renal tubular acidosis

• Redistribution:– Acidosis– Cellular breakdown (Rhabdomyolysis, Hemolysis, Tumor lysis

syndrome, Burns)– Drugs (digoxin, beta blockers, succinylcholine)– Insulin deficiency

Hyperkalemia• Repeat lytes• Stat IV• ECG

– Peaked Ts, ↓ R waves, prolonged PR, no P waves, sudden VT

• Stop any K+ or contributing drugs• Notify your chief resident/SMR• Continuous cardiac monitoring• 1 amp CaCl or Ca gluconate 10%• 1 amp D50W IV then Humulin R 10 units IV• Ventolin• Lasix 20-40mg IV• 1 amp sodium bicarbonate (NaHCO3)• kayexalate: 30 g PO/PR q4h• Persistently high, call nephrology for dialysis

Post-Op Fever

• The 5 W’s:– Wind (atelectasis & pneumonia)– Water (UTI)– Wound– Walk (DVT, PE)– What did we do?

• (surgery, drugs, IV sites, blood products)

Chest Pain &/or SOB• Assess pt:

– ABC’s, vitals– Hx– PE

• Do you need further investigations:– CXR– CK and Trops– ECG for to r/o MI or AFib

• Remember:– Always think PE in the setting of desaturation &

tachycardia– Call for help early if pt unstable or you feel

uncomfortable: chief / SMR / CCRT/ RACE team

ECG• Rate

– 300-150-100-75-60-50• Rhythm

– P before every QRS, QRS after every P– PR interval (AV blocks), QRS interval (BBB)

• Axis– Positive QRS in leads I and aVF

• Intervals– QRS <0.12, PR 0.12-0.20

• Hypertrophy– RVH: R wave progression decreases from V1 to V6– LVH: S in V1 + R in V5 > 35 mm

• Infarct– ST depression, ST elevation– T wave inversions, Q waves

Post-op Acute MI• ABC’s• MONA

– Morphine– Oxygen– Nitroglycerin– Aspirin (160mg chewed)

ACEi, B-blocker, CCB, Statin, Diet

• Call Race team, CCRT or SMR, ?PCI

Post-op Afib• Appropriate Hx & Physical• Distinguishing features

– AFib vs. MAT– New onset AFib vs. known hx– Rate controlled vs. rapid– Symptomatic vs. not– Exacerbating factors (MI, lytes, TSH, MS)

• Acute Treatment– Metoprolol IV boluses or push (x3 q 15 min)– Diltiazem IV push– Digoxin IV push (with concomitant CHF)– Start oral B-Blockers for long term rate control

( > 3mm), pericholecystic fluid, and sonographic Murphys sign– CT – wall thickening, pericholecystic fluid, subserosal edema– HIDA – (sens 97%; spec 90%) failure to see contrast in gallbladder/cystic duct

• Management:– IV fluid rehydration, NPO, antibiotics (cipro/flagyl, amp/gent/ flagyl),

analgesia (toradol/morphine), conservative management or cholecystectomy if presentation within first 48 hrs or if patient deteriorates. May consider percutaneous cholecystostomy tube if patient not good operative candidate.

• Signs:– abdo distention, diffuse peritonitis, fever, +ve FOB, increased WBC (often

> 20 000), increased lactate, metabolic acidosis• Imaging:

– Plain films: ileus, thumbprinting, gas in bowel wall or portal venous system– CT (with IV contrast)– (imaging modality of choice) bowel wall edema, gas

in the bowel wall, decreased bowel wall enhancement, occlusion of SMA/LMA, gas in the portal venous system

– Angiography – site of occlusion of mesenteric vessels, can determine whether embolic occlusion, thrombotic occlusion or vasospasm,

• Management:– Aggressive IV fluid resuscitation, foley in, analgesia, correction of

electrolyte imbalances, antibiotics (tazocin), +/- CTA of abdo/pelvis, ICU admission, urgent laparotomy for resection of necrotic bowel – if entire small bowel compromised patient is palliative, revascularization may be required intra-op or via anti-thrombolytics depending on etiology. Second look laparotomy in 24-48 hours to check for further necrotic bowel, esp. if during first laparotomy bowel was resected or there were areas of questionable viability.

– Hematuria CBI and trial of void if u/o clear– Trauma Urethral injury, false passage, renal injury– Pyelonephritis Consider septic stone & ? Solitary kidney

ENT Emergencies

• Epistaxis– Anterior Bleeds– Posterior Bleeds

• Peritonsillar Abscess

Epistaxis

• When assessing a patient in the ER, it is important to determine if the patient is still bleeding, is this an anterior or posterior bleed?

Anterior Bleeds• Very common, occur from vessels which anastomose & create

Kiesselbach’s plexus

1. Ask the patient to gently blow the nose to clear out any clots.2. Use suction if needed to rid yourself of clots/excess blood.3. Use cotton swabs with lidocaine and epinephrine to achieve a

vasoconstrictive effect.4. Take a look with your nasal speculum and see if there are areas of

bleeding.5. Use silver nitrate cautery if there is a bleeding vessel, do NOT!

Cauterize both sides of the septum.6. If bleeding does not stop move on to packing with Vaseline gauze

or murocel packs.7. Remember to give medications for pain (Tylenol 3/Percocet) and

Keflex to prevent toxic shock syndrome from the packing. Have the patient return in ~2 days to remove packs.

8. Sometimes the bleeding still doesn’t stop and you may have a posterior bleed which will require a nasal pack. Posterior bleeds are usually caused by the sphenopalatine artery.

Posterior Bleeds

• Technique - Foley catheter (10-14F 30-mL balloon)

a) Apply ‘muco’ nasal ointment 2% to the catheter.b) Insert the catheter into the nostril.c) Visualize the catheter tip in the back of the throat.d) Inflate the balloon with up to 10 mL of sterile water. (Do

not fully inflate the balloon to 30 mL.)e) Withdraw the balloon gently until it seats posteriorly.f) Pack the anterior nasal cavity with a balloon device,

nasal tampon (eg, Rhino Rocket), or layered ribbon gauze.

g) Apply a padded umbilical clamp across the catheter to prevent alar necrosis and to keep the balloon from dislodging.

Peritonsillar Abscess Needle aspiration: Needle aspiration is

used for symptom relief and is the criterion standard for diagnosis. Lidocaine with epinephrine should be used to anesthetize the area. A 16- to 18-gauge needle with a 10-mL syringe should be used to aspirate from the area that is most fluctuant. A needle guard may be used to prevent accidental carotid artery puncture due to the tip of the needle migrating too far posteriorly. Only 0.5 cm of the needle needs to be exposed. If a needle guard is unavailable, a curved clamp can be used to expose a small portion of the needle before inserting it into the area for aspiration. Since the superior pole is the most common place for the abscess to develop, that is usually the first place aspirated if the entire tonsil looks or feels boggy. Aspiration of the middle one third and then the lower one third should then be attempted if pus is not returned from the superior pole.

Peritonsillar Abscess

• Abscess I&D:– After lidocaine with epinephrine local infiltration, a No.

11 blade scalpel may be used to incise a very large PTA, allowing the purulent drainage to flow freely as the abscess cavity decompresses. Allow the patient to hold the Yankauer catheter tip and to suction the pus, rather than swallow it. Give analgesia medications and Clindamycin 600 mg po TID for ~10 days.

• Tonsillectomy:– may be used for recurrent peritonsillar abscesses

associated +/- of each• Consults – wide range of cases• Have office phone numbers & addresses on

hand for arranging follow up

Plastics• SJH staff are very particular with punctuality

and dress for clinic• White coats must always be worn if in

greens and outside of the OR • Always be on time for the start of staff

clinics and especially for SJH resident clinics Friday mornings

• Its a preceptor based system at SJH so if you are sick make sure you let your staff or staff office know

General Tips

• Keep up with reading/knowledge• Be on time & Be responsible• Get to the OR before your staff does• Work hard, don’t be lazy• Enjoy time off when you get it• RNs can be your best friends or your

worst enemy!

General Tips• Teach the Clerks• Take advice from your seniors• If you think about calling your senior or staff,

CALL them• If you are overwhelmed with a sick pt call your

senior, the CCRT, RACE team, and/or the SMR• If someone is nasty to you, chances are they

are nasty to everyone!• Keep a balanced life

– family, friends, physical activity, hobbies, etc
