Case 1
70-yo M with unknown PMHx was brought into ED after being
found down. Pt was found to have displaced hip fracture and was
taken to OR for ORIF. Pt initially did well post-op, but 48 hrs after
admission pt started having tachycardia, hypertension, fever, and
agitation.
What are some differential diagnosis?
3
What are the stats?
• There are an estimated 8 million people in the US dependent
on alcohol
• 500,000 people per year are admitted for pharmacological
management of alcohol withdrawal
• Mild to moderate symptoms begin as early as 6 hours after the
last drink
•
4
Most vulnerable patients are those have had long and
sustained periods of drinking with abrupt cessation. Binge
drinkers are less at risk.
Signs and Symptoms of Alcohol Withdrawal
The signs and symptoms of alcohol withdrawal include but are not
limited to:
• Nausea/vomiting and generalized GI symptoms
• Tactile disturbances
• Auditory and visual hallucinations
• Tremors or tremulousness
• Diaphoresis
• Anxiety and agitation
• Headache
• Altered Mental Status, Disorientation
5
What is the CIWA-Ar score?
• A score of 0 – 7 is given for 9 components and 0-4 for 1 component
A sum total of the 10 components score is calculated for a CIWA-Ar Score
Symptom
CIWA-Ar Scale Description
Nausea/vomiting
0- none; 1- mild nausea, no vomiting;
4- intermittent nausea; 7- constant nausea, frequent
dry heaves & vomiting.
“Is your stomach upset?”
Tremors
0- no tremor; 1- not visible but can be felt;
4- moderate w/ arms extended; 7 - severe, even w/
arms not extended.

0- not present; 1- very mild; 2- mild; 3moderate; 4- moderately severe; 5- severe;
6- very severe; 7- extremely severe
Explanation of the CIWA-Ar Score
Scale for Scoring:
Total Score =
0 – 9: absent or minimal withdrawal
10 – 19: mild to moderate withdrawal
> 20: severe withdrawal
• Prophylactic medication should be started for any patient with
a total CIWA-Ar score of 8 or greater
• Total CIWA-Ar score 15 or higher should be on scheduled
medication (Scheduled + PRN for breakthrough method) and
reassessment every hour for at least 8 hours until score is < 8.
• Consider transfer to ICU if score > 35
9
What is Delirium Tremens?
• The most severe form of alcohol withdrawal
manifested by altered mental status and autonomic
hyperactivity which can progress to cardiovascular
collapse
• Signs and Symptoms: (in addition to those of basic
alcohol withdrawal)
• Hypertension
• Tachycardia
• Hyperthermia
• Severe Agitation
• Diaphoresis
10
Delirium Tremens
• Approximately 5% of drinkers are at risk for delirium tremens
• DTs usually manifest 48-96 hours after last drink
• DT is associated with mortality rate of up to 5% (significantly
reduced from 37% in the early 20th century)
• Arrhythmias are the most common cause of death in DTs
• Greater mortality with older age, preexisting pulmonary disease and
liver disease

Withdrawal symptoms timeline

Watch Out For!!
• Hypovolemia- result of diaphoresis, hyperthermia, vomiting,
tachypnea
• Hypokalemia – due to renal and extra-renal potassium losses,
alterations in aldosterone levels, changes in cellular potassium
distribution
• Hypomagnesaemia- predisposes patients to arrythmias and
seizures
• Hypophosphatemia
13
Case 2
40-yo M with h/o alcohol abuse presented with palpitations,
nausea/ vomiting, and tremors.
Patient drinks half a pint of vodka daily and reports that his last
drink was approximately 12 hours prior to admission. On further
questioning, pt reports history of alcohol withdrawal seizures and
has been admitted to OSH ICUs in the past for alcohol withdrawal.
In the ED, patient is tremulous, afebrile, has regular tachycardia,
slightly hypertensive.
Q: Where should this patient be managed?
a.) Medicine Floor
b.) Intensive Care Unit
c.) Discharged Home

What’s in Quest CIWA order set?
• Vital signs q4h if CIWA < 10, otherwise every 1 hour assess
patient
•
Cardiac monitoring, continuous pulse oximetry, fall/seizure/
aspiration precautions, labs, imaging
• Medications: are based on CIWA-Ar Score previously discussed
• If NPO- Lorazepam (or Diazepam may be used)
•

PRN IV Lorazepam 2mg q1h for CIWA-Ar 10-15
PRN IV Lorazepam 4mg q1h for CIWA-Ar > 15
• If taking PO, Chlordiazepoxide
• DO NOT order both
17
What’s in Quest CIWA order set?
• Multivitamins:
• If NPO: “Banana bag”: NS with 100mg thiamine, 1g folate, and
multivitamin
• If can take PO, order PO vitamins
• No increased benefit of infusion, if can take PO give them PO
vitamin replacement
• Case Management Referral for discharge planning
• Social Work referral
• Dietitian referral
• Psych consult for alcohol dependence
18
Not in the order set?
• Electrolyte levels
• Electrolyte repletion
19
Post Test:
Which protocol do you initiate to monitor and manage alcohol
withdrawal symptoms?
Which electrolytes do you check specifically in alcohol withdrawal
management?
What IVF and medications do you order?
At what time mark past the last drink is the patient at greatest risk
for alcohol withdrawal seizures? For DTs?
Under what circumstances would you call the ICU?
20
Post Test:
Which protocol do you initiate to monitor and manage alcohol
withdrawal symptoms? CIWA-Ar Protocol
Which electrolytes do you check specifically in alcohol withdrawal
management? Mag, Phos, K
What IVF and medications do you order? Banana Bag, IV
Lorazepam
At what time mark past the last drink is the patient at greatest risk
for alcohol withdrawal seizures? 6-48 hours For DTs? 48-96 hrs after
last drink.
Under what circumstances would you call the ICU?
• Total CIWA-Ar score above 35
• q1h assess required for more than 8 hrs,
• more than 4 mg/hr IV Lorazepam for 3hr or 20 mg/hr Diazepam for 3hr
• Respiratory Distress, suspicion for DTs
21
Summary
• Withdrawal symptoms can start as early as 6 hours from the
last drink. It is always important to ask when the last drink was
taken.
• Use the CIWA-Ar Score on admission to help determine the
patient’s severity of alcohol withdrawal
• Management of moderate-severe alcohol withdrawal, includes:
IV fluid, IV vitamins, and PRN IV lorazepam or diazepam.
• Don’t forget to check and replace electrolytes
