RSI Pharmacology – Jade Daugherty, PharmD

Sedatives

Etomidate:
– Does not inhibit sympathetic tone or myocardial function. Minimal BP and HR changes|
– RSI: 0.3 mg/kg; Procedural sedation 0.1 – 0.2 mg/kg
– Onset 30 – 60 seconds; Peak 1 minute; Duration 3 – 5 minutes
– Can see myoclonus, dose dependent, can be blunted w/ opioids and benzos. Resolves upon paralysis. May cause difficulty w/ procedural sedation.
– Other adverse effects: N/V, lowers sz threshold, mild decrease in IOP and ICP, adrenal suppression (single dose can cause effects for 24 – 72 hrs)
– Consider avoiding Etomidate in Sepsis patients (see CORTICUS trial)

Ketamine:
– Analgesic and amnestic properties
– Nystagmus with amnestic doses
– RSI: 1 – 2 mg/kg
– Exerts sympathomimetic effects: increased HR, BP, CO by lessens reuptake of catecholamines. May not see this in catecholamine depleted patients
– Also causes bronchodilation and anticonvulsant effects

Propofol:
– Short acting sedative hypnotic that enhances GABA activity
– No analgesia; amnestic effects
– Onset 30 sec; Duration 3-10 min
– RSI 1 mg/kg
– Safer in pregnancy
– Adverse effects: hypotension
– Decreased cerebral O2, decrease in IOP and ICP, bronchodilation and anticonvulsant effects

Benzos:
– No analgesia. It does possess anxiolysis, anterograde amnesia, anti-convulsant properties
– Onset 2 – 3 min; Duration 45 – 60 min
Midazolam preferred: RSI 0.1 – 0.3 mg/kg

Paralytics

Depolarizing Blockers – Succinylcholine:
– Be aware of hyperkalemia; therapeutic dose can raise serum potassium 0.5 – 1 mEq/L
– Consider avoiding in burns and crush injuries (delayed rise in serum K), as well as ESRD on HD, sepsis
– Small increase in ICP
** Special considerations: may require higher doses in Myasthenia gravis
** Pseudocholinesterase deficiency -> results in prolonged paralysis (several hours). NDMB (Roc/Vec) are safe for use

Rocuronium – non-depolarizing neuromuscular blocker:
– Dose 0.6 – 1.2 mg/kg (~1.0 mg/kg)
– Onset 60 – 90 seconds; Duration 30 – 60 minutes

Vecuronium – non-depolarizing neuromuscular blocker:
Needs to be reconstituted
– Dose 0.08 – 0.1 mg/kg (~ 0.1 mg/kg)
– Onset 2 – 3 minutes; Duration 25 – 45 minutes

If you use the longer acting paralytics, sedate appropriately

Guide to Pediatric ED – Dr. Penrod
– EPIC Order Sets: “Peds ED Treatment ____”
Examples: Neonatal Fever (0 – 7 d, 7 – 28 d, > 28 d), Sepsis, Status Epilepticus, Asthma, NAT, Trauma, DKA, more

– Discharge teachings: Get dot phrases from other attendings (i.e. Sandy Herr)

– Admission: bed request > .admitresidentnotification > TigerText (login: phys___@Norton) > ask admit resident when they call if it is ok to put in “ready for dispo” order

– Tylenol 15 mg/kg q6 hrs; Ibuprofen 10 mg/kg q 6 hrs – can alternate q3 hrs
– Versed: PO 1 mg/kg/dose, IN 0.2-0.3 mg/kg/dose, IV 0.1 mg/kg/dose
– CTX: Meningitis 50mg/kg/dose q12hrs, non-meningitis 75 mg/kg/dose daily
– Amox: 50 mg/kg/day, daily for GAS pharyngitis; 90 mg/kg/day divided BID for PNA and AOM

– IVF bolus: 22 cc/kg over 1 hr
– mIVF “4-2-1”: 4 cc/kg/hr for first 10 kg, 2 cc/kg/hr for second 10 kg, 1 cc/kg/hr for each additional kg

Abdominal Ultrasound – Dr. Baker
RUQ US: just below the R costal margin, or X minus 7 mm (7 mm to right of xiphoid process)
Maneuvers to assist: deep breath, left lateral decub
Portal triad (portal vein, hepatic artery, CBD < 7mm normal & > 10 mm + 1mm/decade life abn) makes an exclamation point w/ GB

Cholecystitis: gallstones, anterior* wall > 3mm, sonographic Murphy’s, pericholecystic fluid

Choledocolithiasis: “double barrel” sign

*important to measure anterior wall as posterior acoustic enhancement makes the posterior wall appear thicker due to fluid filled structure enhancing conduction of sound waves

SANE Lecture – Amanda Corzine, MSN, SANE-A
Assault exams/kits done within 96 hours/4 days, sometimes up to 5 days
All male/females 12 yrs and older

Center for Women and Familes (CWF) respond to SA and DV victims as an advocate

Patient may choose to report or not to police. Kit will be destroyed in 1 year if they choose to not report.

Dry swabs for wet surfaces, wet swabs for dry surfaces. Don’t package wet evidence, allow it to fully dry.

Place swab in envelope cotton part down. Do not lick envelope.

EMS Radio Calls Part 2: Dr. Orthober
– Discontinuing IV after Dextrose given: is patient now AAOx4, decisional, clear reason for hypoglycemia, have family members

ROSC ECGs

Check out this very brief Amal Mattu article about that pesky ECG after ROSC. Bottom line: Wait at least 8 minutes to obtain the ECG if you obtain ROSC. This isn’t that wild of an idea, and often it takes a good 10 minutes to set up the machine and stop doing your other resus tasks. But don’t be compelled to get the ECG as fast as possible, as the delay of 8 minutes can reduce false + STEMI. Check out this long article he cites.

Conference 07/07/2021

Small Group Lecture: Bradycardia – Dr. Fisher
Case 1 – Symptomatic bradycardia. Initial management ABCs. GCS 8, however GCS score only validated for trauma patients. Would not intubate until after we attempt to resuscitate first: O2, monitor, x2 LBIV, check POC Gluc, Trop, Electrolytes, EKG. Start w/ 0.5 – 1.0 mg Atropine q3 min to 3 mg max. Consider Epi as well. Can transcutaneous pace. See transvenous pacing link: https://room9er.com/2020/08/13/transvenous-pacing/

Case 2 – Bradycardia w/ interior STEMI. Remember “MONA”. Recent studies have show increased in-hospital mortality w/ morphine, consider fentanyl. AVOID trial (no benefit in O2 w/ SaO2 > 94%). Give ASA. For Nitro, longstanding teaching to avoid NTG in inferior MI as it is preload dependent. However, there may be benefit to giving carefully.

Case 3 – Bradycardia in BB vs CCB OD. CCB poisoning usually causes hyperglycemia, whereas BB poisoning may cause hypoglycemia. Activated charcoal if ingestion w/i 1-2 hrs. Whole bowel irrigation should be considered for large ingestion of sustained-release medications, as these intoxications can outstrip all other therapeutic modalities. Early intubation. For patients with hypotension who require intubation, try to quickly achieve hemodynamic stability prior to intubation if possible. Treat w/ Glucagon, IV Calcium, Hyperinsulinemia euglycemia. Atropine rarely works.

Tick-born Diseases – Dr. Buchanan
Lyme Disease – Can present w/ erythema migrans, later followed w/ arthralgias, Bells’ Palsy or other neurologic sx, or heart blocks. Antibody panels usually negative during rash phase.

Rocky Mtn Spotted Fever – vasculitis w/ maculopapular rash, starts distally. Labs w/ thrombocytopenia and mild transaminitis.

Ehrlichiosis – similar labs to RMSF, but leukopenia. Lone star tick
Anaplasmosis – similar presentation to Ehrlichiosis, but carried by Deer tick/Blacklegged tick

Can treat all w/ doxy. Lyme disease CTX for neuro sx. Lyme dz alternative tx w/ Amoxil + cephalosporin.

Babesiosis – intracellular parasite. Fever, hemolytic anemia, DIC. Cells classically show “Maltese Cross”

Tularemia – wound w/ proximal LAD. Can also present w/ conjunctivitis, pharyngitis, PNA, or typhoidal sx.

Tick Borne PPx: Ixodes tick -> greater than 36 hrs or engorged tick -> w/i 72 hrs since removal -> they can take doxy -> Lyme dz is endemic

Clinical Pathway: Ectopic – Dr. Cook and Dr. French
~ 1:50 pregnancies in North America. 6% – 16% of patients that present to ED w/ 1st trimester bleeding or pelvic pain.

The discriminatory value is that level of hCG above which all normal intrauterine pregnancies should be seen: 1,500 for TVUS; 6,500 for TAUS.

IUP is gestational sac PLUS yolk sac and/or fetal pole. Gestational sac alone is not IUP
