ED Rounds – Oncologic Emergencies and Emerging Treatments

ED Rounds – May 2018

Dr. Paul Frankish

 

Take Home Points

  1. In patients on Immunotherapy for cancer beware of diarrhea or dyspnea, as it may represent an autoimmune side effect.

  2. LMWH is the treatment of choice for the duration of Malignancy associated PE.

  3. SVC obstruction is “sneaky” and new dyspnea is far more common than facial swelling.

 

Immunotherapy

 

 

 

 


Febrile Neutropenia

A single oral temperature >38.3 deg C

or

A sustained oral temperature >38 deg C

with

An absolute neutrophil count (ANC) less than 500 cells per microliter (0.5 x 109/L)

 

*Far and away one of the most common oncologic presentations to the ED

*70% hematologic and 30% solid organ malignancies

*Treatment Timelines (as per IDSA):

1.STAT CBC within 10 minutes

2.Broad empiric antibiotics within 60 minutes

 

History

1.Diagnosis

2.Date and type of last Chemo

3.Use of G-CSF

4.Use of antimicrobials

5.History of prior infection

6.PMH/surgical history

7.Medications/Allergies

 

Exam

1.Mental Status

2.Volume Status

3.Oral Mucosa

4.Skin/Catheter Sites

5.Respiratory

6.Cardiovascular

7.Abdomen

 

Treatment

*Imipenem 500 mg IV Q6H or

*Pip/Tazo 3.375 gram IV Q6H or

*Cipro 400 mg IV and Vanco 1 gram IV Q12H if penicillin allergic

*Consider adding Vanco to monotherapy if:

1.IV Catheter Infection

2.Gram positive organism not yet identified

3.MRSA Colonization

4.Hypotension/Shock

 


SVC Obstruction

*Subacute SVCO results in milder symptoms like facial swelling, cough, dyspnea, facial redness, dilated superficial veins.

*Acute SVCO is more severe and can result in altered LOC, increased ICP, airway obstruction.

*Test of choice is a contrast enhanced CT chest

 

 

Treatment

1.Elevate HOB

2.Dexamethasone 10 mg IV

3.Symptom control

4.Airway management if indicated

5.Urgent Radiation Oncology Consult

6.If known Small Cell Lung Cancer, then worth a call to Medical Oncology

 

 


 

Pulmonary Embolus

*New dyspnea of unknown etiology in patient with active malignancy is a PE until proven otherwise

*Alternate explanations for new dyspnea are pericardial effusion, SVCO, lung tumor burden, anemia.

*Preferred treatment is LMWH indefinitely

 

Investigation of choice is CTPA

 

ECG may show S1QT3 – But don’t rely on this sign

PoCUS may also be helpful for initial triage of acute dyspneic patient – look for dilated RV and IVC

 

Treatment

*Dalteparin 200 units/kg sc for 1 month

then

*Dalteparin 150 untis/kg sc thereafter

*Main evidence for LMWH over warfarin comes from CLOT trial

*50% reduction in recurrent VTE with LMWH vs. warfarin

*Presumed to be because of poor tolerance of PO meds in patients with cancer nauseated from chemo

*May not be relevant in era of modern anti-emetics and anticoagulants, data pending

 


 

Epidural Spinal Cord Compression

1.Back pain (90% of cases)

2.Motor weakness

3.Sensory impairment

4.Autonomic dysfunction

5.Perianal numbness

6.Conus medullaris syndrome

 

Investigations and Treatment

*Dexamethasone 10-20 mg IV immediately if SCC is suspected

*MRI is preferred (generally T/L spine)

*Radiation Oncology if previously diagnosed malignancy

*Neurosurgery if new diagnosis of malignancy

ED Rounds – Oral Rehydration in Children

Pediatric Dehydration and Oral Rehydration

ED Rounds Presentation by: Dr Paul Page


 

  • Volume Depletion (hypovolemia): refers to any condition in which the effective circulating volume is reduced. It can be produced by salt and water loss (as with vomiting, diarrhea, diuretics, bleeding, or third space sequestration) or by water loss alone (as with insensible water losses or diabetes insipidus).
  • Dehydration -refers to water loss alone. The clinical manifestation of dehydration is often hypernatremia. The elevation in serum sodium concentration, and therefore serum osmolality, pulls water out of the cells into the extracellular fluid.

ED Rounds – Ortho Clinic Pathway

ED Rounds – Ortho Clinic Pathway

ED Rounds Presentation by Dr Paul Keyes

 


 

A personal perspective on system review and pathway re-engineering…

 


Rationalization of Process

  • —Every consult is entered by ERP into I3 and printed to accompany copy or ED chart and is placed in clinic book, with a patient sticker placed on clinic appointment sheet.
  • —Non-urgent consults are faxed to orthopedic surgeons offices for triage and cue placement with all other primary care referrals
  • —If subspecialty specific consult requested, then this is faxed to the orthopod of choice’s office. If urgent, then the orthopod on call will sort/laterally refer consult in clinic that week

Outcomes

  • —Collaborative approach ED and ortho
  • —Single process for all orthopedic referrals
  • —Identical sorting of: In ED, Clinic, Ortho office/subspecialty referrals
  • —Legible, billable consults
  • —Timely and appropriate consultations/assessments
  • —Orthopod flexibility as to site of consultation/clinic
  • —Appropriate chain of responsibility from Consult to consultant evaluation

ED Rounds – How Big Are Your Stones

‘How big are your stones….David?’

A Renal Colic Presentation by Brian Ramrattan

 


 


 

 


 

Passing a Stone?

  • <5mm likely to pass without intervention
  • >10mm unlikely to pass without intervention
  • Increased intervention requirements with larger stones
  • Likelihood of stone passing also affected by position
    • Stones at the vesicoureteric junction more likely to be passed than those in the proximal ureter

ED Rounds – Early Pregnancy

Pregnancy of Unknown Location & Early Pregnancy Loss

Presented by: Dr Robin Clouston

 


 

  • Ruling out ectopic pregnancy is a critical issue in evaluation of the symptomatic patient in early pregnancy
  • In women presenting to ED with abdominal pain or pv bleeding, prevalence of ectopic as high as 13%
  • Well known sequelae of missed ectopic
    • Rupture, tubal infertility, possible death
  • Sequelae of false positive diagnosis of ectopic
    • Termination of viable, desired pregnancy

 


Sonographic findings in Ectopic

  • Adnexal mass
    • Simple adnexal cyst – low probability ectopic if < 3mm (5%)
    • Complex adnexal mass – high probability ectopic (90%)
    • Most common location: ampullary or isthmic portion of fallopian tube (95% of ectopics)
  • Isolated free fluid in the pelvis
    • Rarely the only sonographic finding
  • Pseudogestational sac – seen in at most 10% ectopic
  • Normal scan – 15 to 25%

Utility of US with low βHCG

  • ACEP recommends:

“Proceed to transvaginal ultrasonogaphy in symptomatic patients with βHCG less than 1000.”

  • Comprehensive transvaginal ultrasonography has a moderate sensitivity to detect IUP with βHCG < 1000
    • 40 to 67% sensitive
  • For patients whose final diagnosis is ectopic:
    • When βHCG < 1000, TVUS had 86 to 92% sensitivity to detect findings suggestive of ectopic

Safety of Discharge

  • NJEM 2013:3
    • there is limited risk in taking a few extra days to make a definitive diagnosis in a woman with a pregnancy of unknown location who has no signs or symptoms of rupture and no ultrasonographic evidence of ectopic pregnancy.
  • Progression of hCG values over a period of 48 hours provides valuable information:13
    • If failure to fall by 15%
    • And failure to rise by 55%
    • …most likely diagnosis is ectopic pregnancy

Morin L et al. Ultrasound Evaluation of First Trimester Complications of Pregnancy. J Obstet Gynaecol Can 2016;38(10):982-988

 

 


 

A reasonable approach

In the pregnant patient with vaginal bleeding and / or abdominal pain:

  • Always perform bedside US to establish ?definitive IUP
  • Do not rule out ectopic pregnancy in patients with empty uterus and βHCG < 1000
  • Do obtain a comprehensive TVUS when bedside US does not confirm IUP regardless of βHCG

In the pregnant patient with vaginal bleeding and / or abdominal pain:

  • When TVUS is delayed or remains non-diagnostic, involve obstetrician to aid in risk stratification and management
  • Reliable, hemodynamically stable patients may be discharged with follow up
  • Expedited TVUS (next day)
  • Repeat βHCG in 48h

 


 

Take Home Points

  • Do obtain a comprehensive TVUS when bedside US does not confirm IUP regardless of βHCG
  • Do not rule out ectopic pregnancy in patients with empty uterus and βHCG < 1000
    • Clinical judgment: safe discharge planning vs admission
    • Low threshold to involve Obs-Gyn for these cases
  • Early pregnancy loss is diagnosed by US when:
    • CRL >/= 7mm with no FRH
    • Mean sac diameter >/= 25mm and no embryo
  • Expectant, medical and surgical management are equally effective and safe in treatment of EPL
    • Patient preference may guide decision making

ED Rounds – Delirium in the ED

Delirium in the ED: How can we help?

Presented by: Dr Cherie-Lee Adams

 


Incidence of Delirium

  • 40% admitted patients >65yo
  • 10-20% on admission
  • 5-10% more during admission

Increased Risk of Delirium:

  • Male
  • >60yo, more prevalent >80yo
  • Hearing/visual impairment
  • Dementia
  • Depression
  • Functional dependence
  • Polypharmacy
  • Major medical/surgical illness


DSM-V Criteria

  • A) Disturbance in attention and awareness
  • B) Disturbance is ACUTE
  • C) Concurrent cognitive impairment
  • D) Not evolving dementia, nor coma
  • E) Can be explained by Hx/Px/Ix

 


 

Non – Pharmacological Approach

  • Nutritional support
  • Optimize hearing/sight
  • Maximize day/night/date/time cues
  • Minimize pain
  • Rehabilitate- ambulate, encourage self-care
  • Avoid restraints

Pharmacological Options

  • Treat only if distress/agitated/safety concern
      • don’t treat hypoactive delirium, wandering, or prophylactically
  • monotherapy
  • low dose
  • short course
  • Benzos- reserve for withdrawal
  • APs
        • Haldol 0.25-0.5mg
        • risperidone 0.25mg od-bid
        • olanzapine 1.25-2.5mg/d
        • quetiapine 12.5-50mg/d

 

Take Home Points

  • Delirium is common, esp in elderly
  • Significant morbidity/mortality associated
  • Brief screening with DTS/bCAM works
  • Intervention focus on limiting pathology, normalizing activities, minimizing drugs
  • Low dose APs for short period for agitation
