Aldrete Score
Calculate the Aldrete score for PACU discharge readiness using five criteria: consciousness, mobility, breathing, circulation, and skin color. Free online tool.
About This Calculator
The Aldrete Score Calculator helps healthcare professionals evaluate a patient's recovery from anesthesia in the post-anesthesia care unit (PACU). Developed by Dr. J. Antonio Aldrete in 1970, this scoring system uses five essential criteria — consciousness, mobility, breathing, circulation, and skin color — each rated from 0 to 2 points for a total possible score of 10. The tool is widely used in hospitals worldwide for both general and local anesthesia recovery assessment.
Each criterion is assessed independently: Consciousness evaluates the patient's ability to respond and interact; Mobility checks voluntary movement of extremities; Breathing assesses respiratory effort and airway reflexes; Circulation compares current blood pressure to pre-anesthetic levels; and Skin Color evaluates oxygenation and perfusion status. A total score of 9 or above indicates the patient is ready for safe discharge from the PACU to a regular ward, while scores of 8 or lower signal the need for continued monitoring.
This assessment is used during the early recovery phase (PACU Phase 1) following surgery. The calculator provides immediate scoring with a visual breakdown of each criterion, helping clinicians make informed decisions about patient readiness for step-down care.
Frequently Asked Questions
What is the Aldrete score used for?
The Aldrete score is used to assess a patient's recovery from anesthesia in the post-anesthesia care unit (PACU). It evaluates five criteria — consciousness, mobility, breathing, circulation, and skin color — each scored 0-2. A total score of 9 or higher indicates the patient can be safely discharged from the PACU.
What is a passing Aldrete score for PACU discharge?
A total Aldrete score of 9 or 10 out of 10 is considered passing and indicates the patient is ready for discharge from the post-anesthesia care unit (PACU). A score of 8 or lower means the patient requires continued close observation and monitoring before discharge.
What are the five criteria of the Aldrete scoring system?
The five criteria are: Consciousness (fully awake 2 pts, arousable 1 pt, unresponsive 0 pts), Mobility (move 4 extremities 2 pts, move 2 extremities 1 pt, unable 0 pts), Breathing (deep breath/cough freely 2 pts, dyspnoea/limited 1 pt, apnoeic 0 pts), Circulation (BP ±20% of pre-anesthetic level 2 pts, ±20-49% 1 pt, ±50% 0 pts), and Skin Color (normal 2 pts, pale/dusky/jaundiced 1 pt, cyanotic 0 pts).
Who developed the Aldrete score?
The Aldrete score was developed by Dr. J. Antonio Aldrete and first published in 1970 in the journal Anesthesia and Analgesia. Dr. Aldrete later revised the scoring system in 1995 in the Journal of Clinical Anesthesia.
Can the Aldrete score be used for both general and local anesthesia?
Yes, the Aldrete score is used to assess recovery from both general and local anesthesia procedures. It evaluates essential life functions that must be regained before a patient can be safely monitored in an unmonitored ward setting.
How is the Aldrete score different from the GCS score?
The Glasgow Coma Scale (GCS) specifically assesses level of consciousness based on eye, verbal, and motor responses. The Aldrete score is a broader post-anesthesia recovery tool that evaluates consciousness along with breathing, circulation, mobility, and skin color to determine PACU discharge readiness.
Is this calculator a substitute for professional medical assessment?
No. This calculator is for educational and reference purposes only and is not a substitute for professional medical assessment. The Aldrete score should always be used by qualified healthcare professionals as part of a comprehensive clinical evaluation in the PACU setting.
