About the RASS Scale

The Richmond Agitation-Sedation Scale (RASS) is a validated tool for objective assessment of sedation and agitation levels in critical patients. Developed in 1999, it has become widely adopted in intensive care units worldwide.

The scale ranges from -5 (unarousable) to +4 (combative), with zero representing an alert and calm patient. Assessment is quick, reliable, and easily applicable at the bedside by trained healthcare professionals.

Clinical Use

RASS is essential for sedation monitoring in ICU, enabling precise titration of sedatives and analgesics, identification of agitation or excessive sedation, and assistance in mechanical ventilation weaning. It is associated with reduced mechanical ventilation duration and hospital length of stay when used in goal-directed sedation protocols.

Perguntas Frequentes

O que é a Escala RASS?

A Richmond Agitation-Sedation Scale (RASS) é uma escala validada de 10 pontos (-5 a +4) usada para avaliar o nível de sedação e agitação em pacientes críticos em unidades de terapia intensiva.

Como é feita a avaliação RASS?

A avaliação RASS envolve três etapas: 1) Observar o paciente (se alerta, escore 0; se agitado, escore +1 a +4). 2) Se sonolento, chamar pelo nome (escore -1 a -3). 3) Se não responde, aplicar estímulo físico (escore -4 ou -5).

Qual é o escore RASS ideal?

O escore ideal varia conforme o objetivo clínico. Para desmame de ventilação mecânica, RASS 0 (alerta e calmo) a -1 (sonolento) é ideal. Para pacientes ventilados em fase aguda, RASS -2 (sedação leve) é geralmente apropriado.

Com que frequência deve-se avaliar o RASS?

O RASS deve ser avaliado regularmente em pacientes críticos, tipicamente a cada 4-8 horas em pacientes estáveis, ou mais frequentemente (a cada 1-2 horas) em pacientes instáveis ou durante titulação de sedativos.

Frequently Asked Questions

What is the RASS Scale?

The Richmond Agitation-Sedation Scale (RASS) is a validated 10-point scale (-5 to +4) used to assess sedation and agitation levels in critical patients in intensive care units.

How is RASS assessment performed?

RASS assessment involves three steps: 1) Observe the patient (if alert, score 0; if agitated, score +1 to +4). 2) If drowsy, call by name (score -1 to -3). 3) If no response, apply physical stimulation (score -4 or -5).

What is the ideal RASS score?

The ideal score varies according to clinical objective. For mechanical ventilation weaning, RASS 0 (alert and calm) to -1 (drowsy) is ideal. For ventilated patients in acute phase, RASS -2 (light sedation) is generally appropriate.

How often should RASS be assessed?

RASS should be regularly assessed in critical patients, typically every 4-8 hours in stable patients, or more frequently (every 1-2 hours) in unstable patients or during sedative titration.
