Altered Mental Status: Adult
A state of abnormal mentation due to serval reason
EMT Standing Orders
- Routine Patient Care.
- Administer oxygen as appropriate with a target of achieving 94 – 98% saturation.
- Assist inadequate ventilations with BVM (bag-valve-mask ventilation). If respiratory arrest occurs, manage airway with OPA/NPA and maintain oxygenation and ventilations with BVM (bag-valve-mask ventilation). Anticipate and avoid aspiration.
- Obtain glucose readings via glucometer.
- If blood glucose < 3.0 mmol \ L or 60 mg/dL with associated altered mental status, refer to Diabetic Emergencies (Hypoglycemia) Protocol – Adult.
- If the patient’s mental status and respiratory effort are severely depressed, (eg narcotic overdose) consider restraint and administer naloxone
- A single dose of NARCAN (4mg) IV/IM. May repeat every 3 – 5 minutes if there is no response or if the patient relapses to a maximum of 12 mg OR
- Patients given naloxone should be transported to the emergency department for further evaluation.
- Consider acquiring 12-lead ECG.
- If trauma can be excluded, transport a patient in the coma/recovery position. If trauma is suspected, see the Advanced Spinal Assessment Procedure.
- Perform stroke assessment. Refer to Stroke Protocol – Adult. as indicated.
- See Poisoning/Substance Abuse/Overdose – Adult.
- Minimize scene time.
- Call for AEMT/Paramedic intercept, if available & assist them in patient care.
AEMT/Paramedic Standing Order:
- Establish IV/IO access.
- For severe respiratory depression, administer naloxone 0.4 – 2 mg IV/IM/IO/SQ/
- For hyperglycemic, give 500 mL bolus 0.9% NaCl IV/IO. See Diabetic Emergencies (Hyperglycemia) Protocol – Adult.
- Advanced airway as indicated.
- If hypotensive (SBP < 90), administer fluid bolus 500 mL 0.9% NaCl IV/IO. Contact Medical Direction for additional fluid or medication orders.
- Assess and monitor cardiac rhythm. Treat as indicated per appropriate protocol.
- If hypotension persists after a 2-litre fluid bolus, consider vasopressors. See Shock Protocol – Adult.
- If the patient is violent or agitated, consider restraint. See Behavioral Emergencies Including Suicide Attempts & Threats Protocol.
PEARLS:
- Altered mental status may be caused by many factors including the following: stroke, drug overdose, infection, hypoglycemia, hyperglycemia or trauma.
- AEMT/Paramedic may titrate use of naloxone in patients with respiratory depression (e.g.: narcotic overdose) to avoid transition to combative behavior by patient
- Use appropriate discretion regarding immediate intubation of patients who may quickly regain consciousness, such as hypoglycemic patients after administration of dextrose, or opiate overdose cases after administration of naloxone.
