## 문제

A nurse is assessing a patient who was admitted 48 hours ago for alcohol detoxification. Which assessment finding would be the highest priority concern indicating severe alcohol withdrawal syndrome?

## 보기

1. New onset of seizure activity with tonic-clonic movements **✔ 정답**
2. Blood pressure of 160/95 mmHg with heart rate of 110 bpm
3. Visual hallucinations of insects crawling on the skin
4. Tremors of the hands with profuse diaphoresis

**정답: 1**

## 해설

Seizure activity is the most life-threatening complication of alcohol withdrawal, requiring immediate intervention to prevent status epilepticus and death. Other findings like hypertension, hallucinations, and tremors are significant but less urgent.

Clinical Priority in Alcohol Detoxification

When assessing a patient in alcohol withdrawal, the nurse must prioritize life-threatening complications using a systematic approach grounded in the pathophysiology of autonomic instability and neuronal hyperexcitability. The central nervous system adapts to the chronic depressant effects of alcohol by downregulating inhibitory gamma-aminobutyric acid (GABA) receptors and upregulating excitatory N-methyl-D-aspartate (NMDA) receptors. Upon abrupt cessation, this neuroadaptation results in a hyperadrenergic state characterized by excessive sympathetic outflow. The Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) protocol is a validated, nurse-driven tool used to monitor progression and guide symptom-triggered pharmacotherapy, as highlighted in the implementation of electronic health record-integrated protocols to standardize management and improve patient safety [1]. However, a critical distinction must be made between symptoms that indicate severe, but expected, autonomic hyperactivity and those that herald progression to a life-threatening neurological emergency.

Analysis of Assessment Findings

The highest priority finding is new onset of seizure activity with tonic-clonic movements. This represents a progression from simple withdrawal to severe alcohol withdrawal syndrome, specifically withdrawal seizures. The pathophysiological basis is unopposed glutamate-mediated excitotoxicity due to the loss of alcohol's GABAergic effect, which lowers the seizure threshold. Withdrawal seizures are typically generalized tonic-clonic in nature, occur within 12 to 48 hours of the last drink, and precede the development of delirium tremens in approximately one-third of untreated patients. This is a time-sensitive neurological emergency requiring immediate intervention to prevent progression to status epilepticus, respiratory compromise, or aspiration. The consensus on managing withdrawal in complex settings emphasizes the necessity of structured protocols to immediately address such high-risk presentations to prevent mortality [2].

The other findings, while clinically significant, represent lower-priority concerns on the hierarchy of physiological instability:

- Blood pressure of 160/95 mmHg with heart rate of 110 bpm reflects significant sympathetic nervous system activation. This is an expected manifestation of the hyperadrenergic state and a key parameter monitored by the CIWA-Ar protocol to titrate benzodiazepine therapy [1]. While requiring treatment to prevent hypertensive crisis, it does not carry the same immediate risk of irreversible brain damage or death as an active seizure.

- Visual hallucinations of insects crawling on the skin (formication) are a perceptual disturbance indicative of moderate-to-severe withdrawal. These are distressing but are not directly life-threatening. They represent a tactile and visual misperception that will resolve with appropriate pharmacological management guided by CIWA-Ar scores.

- Tremors of the hands with profuse diaphoresis are classic early signs of autonomic hyperactivity, typically peaking within 24 to 48 hours. These symptoms, while uncomfortable, indicate a state where the patient is still able to protect their airway and maintain cardiovascular stability with supportive care and medication.

Using the airway, breathing, and circulation (ABC) framework, an active tonic-clonic seizure threatens the airway and effective breathing, placing it at the apex of nursing priorities. The nurse must immediately implement seizure precautions, ensure airway patency, administer benzodiazepines as prescribed, and prepare for potential escalation of care.References (research sources)

## 임상 시나리오

Alcohol Withdrawal Seizure ManagementPrioritizing Life-Threatening CNS Hyperexcitability
A new-onset tonic-clonic seizure during withdrawal signals a progression to severe withdrawal syndrome. The priority is airway protection, seizure termination, and prevention of status epilepticus.

Administer benzodiazepines (e.g., lorazepam or diazepam) immediately per protocol. This targets the underlying GABA deficiency and halts glutamate-mediated excitotoxicity.

CautionSeizure activity is the highest priority over autonomic signs like 160/95 mmHg BP or tachycardia. Uncontrolled seizures can rapidly lead to delirium tremens, carrying up to a 5% mortality rate.

## 핵심 개념

- **Alcohol Withdrawal Seizures** — Generalized tonic-clonic seizures occurring 12-48 hours after last drink due to unopposed glutamate excitotoxicity and GABA downregulation.
- **Delirium Tremens (DTs)** — Severe alcohol withdrawal syndrome characterized by profound confusion, autonomic instability, and hallucinations, with a mortality rate of up to 5% if untreated.
- **CIWA-Ar** — Clinical Institute Withdrawal Assessment for Alcohol-Revised; a validated 10-item scale used by nurses to assess withdrawal severity and guide symptom-triggered benzodiazepine therapy.
- **GABA Receptor Downregulation** — Chronic alcohol exposure causes a compensatory decrease in inhibitory GABA receptors, leading to CNS hyperexcitability upon abrupt alcohol cessation.
- **Glutamate Excitotoxicity** — Neuronal injury caused by excessive stimulation of NMDA receptors by glutamate, a key mechanism in withdrawal seizures due to loss of alcohol's depressant effect.
