Study Notes
Sedation Quiz - Key Concepts
-
Adverse Events of Ketamine Sedation (Emergency Settings):
- Most common adverse event is respiratory depression.
- Other potential adverse events include hypotension, laryngospasm, and allergic reactions.
-
Risk Factors for Difficult Airway Management in Pediatric Sedation:
- Obesity is a primary risk factor.
- Prior surgeries, high anxiety levels, and Mallampati Class I are also considered risk factors.
-
Predicting Difficult Airway Before Sedation:
- Reviewing patient history is the most effective method.
- CT imaging or randomized trials are less effective for this.
- Assessing patient history offers the best prediction.
-
Managing Laryngospasm During Ketamine Sedation:
- Administering epinephrine is a critical step.
- Providing positive pressure ventilation is another effective method.
- Increasing ketamine dose may be helpful in some instances, but this is not typical treatment.
- Performing immediate tracheostomy is extreme and unlikely to address the issue.
-
Monitoring Device for Hypoventilation During Moderate Sedation:
- Capnography is essential for detecting early hypoventilation.
- Other devices, such as pulse oximeters, ECGs and non-invasive blood pressure monitors, do not solely evaluate the ventilation aspects of sedation.
Monitoring Children After Sedation
-
Minimum Monitoring Time After Sedation (Children):
- Monitor until the child regains full consciousness.
- 15 minutes after the procedure is a good minimum duration for monitoring.
- 30 minutes (regardless of sedation depth) is also important for monitoring.
Pulse Oximetry During Pediatric Sedation
-
Accuracy of Pulse Oximetry:
- Pulse oximetry detects hypoxia before adverse effects often become apparent.
- Early hypoventilation will show up as a result of changes to respiration.
- Capnography can be used to help supplement pulse oximetry.
Treating Apnea During Sedation Due to Obstruction
-
First-Line Treatment for Apnea:
- Providing positive pressure ventilation is the primary treatment.
- Administering a reversal agent or increasing the sedative dose are not first-line treatments.
Managing Bradycardia During Sedation
-
Action for Persistent Bradycardia:
- Administering atropine directly counteracts bradycardia.
- Increasing sedation is not the right approach if bradycardia appears.
Treating Midazolam Overdose
-
Treatment for Midazolam Overdose:
- Administering flumazenil is a common treatment for midazolam overdose.
- Oxygen is important for any patient with an overdose.
- Naloxone may also play a role depending on the patient.
Pre-Sedation Fasting Guidelines (Pediatric Patients)
-
Purpose of Fasting:
- Pre-sedation fasting guidelines are primarily intended to prevent pulmonary aspiration.
- Enhancing the efficacy of sedation medications, reducing anxiety, and prolonging sedation are not the primary reasons.
Nitrous Oxide Sedation Oxygen Concentration
-
Minimum Oxygen Concentration:
- 30% concentration of oxygen is required, at a minimum.
- 20% is not sufficient.
