NPO Fasting Guidelines

Recommended intervals of fasting from food and clear liquids before sedation or anesthesia, intended to empty the stomach and reduce the chance of vomiting and aspiration during the procedure.

Related: Aspiration, Moderate Sedation
ASA Physical Status Classification

A six-category scale (I through VI) describing a patient's overall health and anesthesia risk, used to guide preparation, monitoring, and the setting where care is safely delivered.

Related: Preprocedure History and Physical, NPO Fasting Guidelines
Preprocedure History and Physical

A structured review of the patient's medical, surgical, medication, and allergy history combined with a focused physical exam, done before the procedure to plan safe anesthesia and identify problems needing follow-up.

Related: Medication Reconciliation, ASA Physical Status Classification
Informed Consent

The patient's voluntary agreement to a procedure after receiving and understanding information about its purpose, benefits, risks, and alternatives, documented before sedation or anesthesia begins.

Related: Time-Out
Mallampati Classification

A four-class visual score based on how much of the throat and soft palate can be seen when the seated patient opens the mouth and protrudes the tongue, helping predict difficult intubation.

Related: Preprocedure History and Physical
Medication Reconciliation

The process of obtaining a complete list of the patient's current medications, including over-the-counter products and supplements, and comparing it with new orders to prevent errors and interactions.

Related: Preprocedure History and Physical
STOP-BANG Questionnaire

An eight-item screening tool that scores snoring, daytime tiredness, observed apnea, high blood pressure, body mass index, age, neck circumference, and gender to estimate obstructive sleep apnea risk.

Related: Opioid-Induced Respiratory Depression
Malignant Hyperthermia Susceptibility

An inherited trait that places a patient at risk for a life-threatening hypermetabolic reaction to volatile anesthetics and succinylcholine, identified before the procedure so triggering drugs can be avoided.

Related: Malignant Hyperthermia
Moderate Sedation

A drug-induced state in which the patient responds purposefully to verbal or light touch stimulation, keeps a patent airway, and breathes adequately on their own, though alertness is reduced.

Related: Capnography, Monitored Anesthesia Care
Monitored Anesthesia Care

Anesthesia care in which an anesthesia professional gives sedation as needed and continuously monitors the patient while a practitioner performs the procedure under local anesthesia.

Related: Moderate Sedation, Pulse Oximetry
Capnography

Continuous measurement and display of exhaled carbon dioxide, which reveals hypoventilation and apnea sooner than pulse oximetry alone, especially when the patient is receiving supplemental oxygen.

Related: Pulse Oximetry, Opioid-Induced Respiratory Depression
Pulse Oximetry

A noninvasive estimate of arterial oxygen saturation obtained by shining light through tissue, useful for detecting hypoxemia but delayed and unreliable for detecting inadequate ventilation.

Related: Hypoxemia, Capnography
Opioid-Induced Respiratory Depression

Slowing and shallowing of breathing caused by opioids, which can progress to low oxygen and apnea, particularly when opioids are combined with sedatives or given to high-risk patients.

Related: Capnography, Reversal Agents
Reversal Agents

Drugs such as naloxone and flumazenil that counteract opioid or benzodiazepine effects, used when sedation or breathing depression is deeper or longer than intended.

Related: Opioid-Induced Respiratory Depression, Moderate Sedation
Multimodal Analgesia

Combining two or more pain-relieving drugs or techniques with different mechanisms so that each can be used at a lower dose, improving comfort and reducing side effects.

Related: Postoperative Nausea and Vomiting
Propofol

A short-acting intravenous sedative-hypnotic with rapid onset and quick recovery that can cause low blood pressure, apnea, and loss of airway reflexes, so close monitoring is required.

Related: Moderate Sedation, Bag-Mask Ventilation
Bag-Mask Ventilation

Delivery of oxygen through a tight-sealing mask and self-inflating bag when a patient's breathing is inadequate, a core rescue skill whenever sedation is provided.

Related: Hypoxemia, Propofol
Phase I Recovery

The first stage of postanesthesia care, where the patient is monitored closely for airway, breathing, circulation, and level of consciousness until vital functions are stable.

Related: Aldrete Score, Phase II Recovery
Phase II Recovery

The later stage of recovery for ambulatory patients who are awake and stable, focusing on pain, nausea, mobility, and readiness for discharge home.

Related: Phase I Recovery, Discharge Criteria
Aldrete Score

A scoring tool that rates activity, respiration, circulation, consciousness, and oxygen saturation to objectively determine whether a patient is ready to leave Phase I recovery.

Related: Phase I Recovery, Postanesthesia Discharge Scoring System
Postanesthesia Discharge Scoring System

A tool that assigns points for vital signs, activity, nausea and vomiting, pain, and surgical bleeding to decide whether an ambulatory patient meets criteria for discharge.

Related: Discharge Criteria, Aldrete Score
Laryngospasm

A reflex spasm of the vocal cords that partly or fully closes the airway, often during emergence or with secretions or stimulation, requiring prompt oxygen, airway support, and sometimes medication.

Related: Hypoxemia, Phase I Recovery
Hypoxemia

An abnormally low level of oxygen in the blood, detected by pulse oximetry or blood gas, that calls for airway assessment, oxygen, and correction of the underlying cause.

Related: Pulse Oximetry, Laryngospasm
Emergence Delirium

Agitation, confusion, and disorientation occurring as anesthesia wears off, seen most often in children and older adults, which requires calm reassurance, safety measures, and treatment of contributing causes.

Related: Phase I Recovery
Malignant Hyperthermia

A rare hypermetabolic crisis triggered by certain anesthetics, marked by rising temperature, muscle rigidity, acidosis, and rapid heart rate, treated emergently with dantrolene, cooling, and supportive care.

Related: Malignant Hyperthermia Susceptibility
Postoperative Nausea and Vomiting

Nausea and vomiting after anesthesia and surgery, caused by anesthetic drugs, opioids, movement, and patient factors, and managed with preventive and rescue antiemetic therapy.

Related: Phase II Recovery, Multimodal Analgesia
Aspiration

Passage of stomach contents or oral secretions into the lungs, which can cause chemical injury, infection, and airway blockage; prevention relies on fasting and protecting the airway.

Related: NPO Fasting Guidelines, Laryngospasm
Discharge Criteria

A defined set of clinical and functional standards, such as stable vital signs, controlled pain, and ability to walk, that a patient must meet before leaving the facility.

Related: Postanesthesia Discharge Scoring System, Responsible Adult Escort
Teach-Back Method

A teaching approach in which the patient restates instructions in their own words, letting the nurse confirm understanding and correct gaps before the patient goes home.

Related: Written Discharge Instructions, Discharge Criteria
Responsible Adult Escort

A capable adult who accompanies the patient home and stays with them after sedation, a standard requirement because lingering drug effects impair judgment, balance, and the ability to respond to problems.

Related: Discharge Criteria, Driving and Machinery Restrictions
Written Discharge Instructions

Printed information covering wound care, medications, diet, activity limits, warning signs, and whom to contact, given so patients can refer to guidance after leaving the facility.

Related: Teach-Back Method, Follow-Up Phone Call
Follow-Up Phone Call

A structured call placed after discharge to check symptoms, pain control, understanding of instructions, and satisfaction, and to identify complications that need further care.

Related: Written Discharge Instructions
Driving and Machinery Restrictions

Limits on driving, operating equipment, or making important decisions after sedation or anesthesia, because reaction time and judgment stay impaired for up to 24 hours even when the patient feels normal.

Related: Responsible Adult Escort, Discharge Criteria
ASPAN Standards

Evidence-based practice statements from the American Society of PeriAnesthesia Nurses covering assessment, monitoring, staffing, and discharge for patients receiving perianesthesia care.

Related: Discharge Criteria, Phase I Recovery
Time-Out

A brief pause immediately before a procedure in which the team verbally confirms patient identity, procedure, site, consent, and allergies to prevent wrong-patient and wrong-site errors.

Related: Informed Consent
Handoff Communication (SBAR)

A structured way to transfer patient information using Situation, Background, Assessment, and Recommendation, reducing omissions and misunderstandings when care passes between providers or units.

Related: Phase I Recovery, Phase II Recovery
