Alcohol Withdrawal Management Erum Iqbal Bajwa Updated June 2015 Objectives Discuss the signs and symptoms of alcohol withdrawal Discuss the components of the revised Clinical Institute Withdrawal Assessment of Alcohol (CIWA-Ar) score Discuss the identification of delirium tremens Discuss when to send a patient to the Intensive Care Unit with severe alcohol withdrawal Discuss the management of alcohol withdrawal on the inpatient ward floor 2 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. Anxiety 0- none, at ease; 1- mildly anxious; 4- moderately anxious or guarded; 7- equivalent to acute panic state Agitation 0 - normal activity; 1 - somewhat normal activity; 4 moderately fidgety/restless; 7 - paces or constantly thrashes about 6 CIWA-Ar Score Symptom CIWA-Ar Scale Description Paroxysmal Sweats 0- no sweats; 1- barely perceptible sweating, palms moist; 4- beads of sweat obvious on forehead; 7- drenching sweat Orientation (0-4) 0- oriented; 1- uncertain about date; 2disoriented to date by no more than 2 days; 3- disoriented to date by > 2 days; 4- disoriented to place and/or person Ask, “What day is this? Where are you? Who am I?” Tactile Disturbances Ask, “Have you experienced any itching, pins & needles (P&N) sensation, burning or numbness, or a feeling of bugs crawling on or under your skin?” 7 0- none; 1- very mild itch, P&N, numbness; 2- mild itch, P&N, burning, numbness; 3moderate itch, P&N, burning, numbness; 4- moderate hallucinations; 5- severe hallucinations; 6- extremely severe hallucinations; 7- continuous hallucinations CIWA-Ar Score Symptom CIWA-Ar Scale Description Auditory Disturbances 0- not present; 1- very mild harshness/ ability to startle; 2- mild harshness, ability to startle; 3- moderate harshness, ability to startle; 4- moderate hallucinations; 5severe hallucinations; 6- extremely severe hallucinations; 7- continuous hallucinations Ask, “Are you more aware of sounds around you? Are they harsh? Do they startle you? Do you hear anything that disturbs you or that you know isn’t there?” Visual Disturbances 0 - not present; 1- very mild sensitivity; Ask, “Does the light appear to be too bright? Is 2- mild sensitivity; 3- moderate sensitivity; its color different than normal? Does it hurt your 4- moderate hallucinations; 5- severe eyes?

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 14 ICU Admission Criteria • Active Seizures • Any suspicion for DTs: • ALL alcohol withdrawal symptoms PLUS: • • • • • Hypertension Tachycardia Hyperthermia- persistent Severe Agitation Diaphoresis • CIWA-Ar Score > 35 on admission or q1h assessments required for more than 8 hrs • More than 4 mg/hr IV Lorazepam for 3hr or 20 mg/hr IV Diazepam for 3hr • Hemodynamic instability or respiratory distress • Severe electrolyte or acid/base disturbances 15 Alcohol Withdrawal Management 16 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 q2h for CIWA-Ar <10 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 22 References Hoffman RS, Weinhouse GL.
