Flashcards in IV sedation Deck (36):
What is conscious sedation?
-Pt. retains an independent airway and can respond appropriately to commands
What is deep sedation?
-Depressed consciousness, partial loss of protective reflexes
What is general anesthesia?
-An induced state of unconsciousness with total loss of protective reflexes
What plane is conscious sedation?
What is Plane 1 anesthesia?
What is plane 2 anesthesia?
-Excitement or Delirium stage
What is plane III anesthesia?
-Surgical anesthesia stage
What is plane IV anesthesia?
-Medullary paralysis or danger stage
What is a medical indication for sedation?
-Mild systemic disease
-Spastic nerve/muscle disorders
-Mild mental/psychiatric disorders
What is a dental indication for sedation?
-Moderately difficult surgery
-Idiosyncratic reaction to LA
What are Medical contra-indications for sedation?
-Severe systemic disease (ASA III)
-COPD (except asthma)
-Medication such as anti-psychotics
-Severe psychiatric Disorder
What are socio-psychological contraindications for sedation?
What is a dental contraindication for sedation?
-Prolonged difficult surgery
What are requirements for ideal sedation?
What are drugs that you can give sublingually or and endotracheal tube?
What route if IV sedation?
What is an advantage of IV sedation?
-Direct to blood 22-122 seconds for hypnotic
-Rapid onset of action
-Can titrate effect rapidly
-Control duration of sedation
-Have access for emergent therapy
If you do IV sedation how many people have to be in the room with you?
How long before surgery should a person not eat food or fluid prior to surgery?
Clear fluid intake should not be taken within how soon of surgery?
Why should you use a capnography?
Because it can identify apnea or airway compromise much earlier than pulse oximetry
When is a temperature recording mandated?
-Only during deep sedation
What does a pulse oximeter measure?
-Arterial oxygen saturation of hemoglobin
-ratio of oxygenated Hb and total Hb
All types of IV sedation should have what monitoring?
-Blood pressure monitoring
-Time based record at least 5 minutes apart
What can be sources of error for pulse oximetry readings?
-Lipids and bilirubin
-Color interferences: nail polish
What does Capnography measure?
-The amount of carbon dioxide in the expired gases
T/F It is now mandated that anyone who does IV sedation whether conscious, deep, or general has to have a capnography.
T/F Increases in end tidal CO2 measured through a capnograph precede the decrease in oxygen saturation measured by pulse oximetry.

What is the alarm low limit for diastolic BP?
What is the alarm high limit for diastolic BP?
What is the alarm low limit for HR?
What is the alarm high limit for HR?
What is the alarm low limit for O2?
