You must have:
JCAHO Definitions
Minimal sedation (______)
1. A drug-induced state during which patients:
- Although _______ and _______ may be impaired, ventilatory and cardiovascular function are unaffected.
anxiolysis;
1. respond normally to verbal commands.
2. cognitive function and coordination
Moderate sedation/analgesia or “_____________”
1. A drug-induced depression of ___________ during which patients respond ________ to verbal commands, either alone or accompanied by light tactile stimulation.
- ______ and _______ maintained
Conscious Sedation
1. consciousness; purposefully
2. Airway and CV
Deep sedation/analgesia
1. A drug-induced depression of consciousness during which patients _______ be easily aroused but respond purposefully following repeated or _________ stimulation. __________ is not considered a purposeful response.
- _______ and _________ may be impaired. Spontaneous ventilation may be inadequate.
- ________ function is usually maintained.
- cannot; painful
* Reflex withdrawal - Ventilatory function and airway patency
- CV
- General anesthesia is a drug-induced _______________ during which patients are not arousable, even by painful stimuli.
- The ability to independently maintain ventilatory function is often impaired.
- Patients require assistance in maintaining a patent airway and _________________ may be required because of depressed spontaneous ventilation or drug-induced depression of neuromuscular function.
- CV function may be impaired.
- loss of consciousness
- positive pressure ventilation

AnMRIis indicated to detect:
One advantage of an MRI is that it does not use ___________
An MRI can take from _____ minutes to _____ hours and involve breath holds.

- Ligament and tendon injuries,
- Spinal cord injuries,
- brain tumors, etc.
radiation.
30, 4
Magnetic Resonance Imaging
- No _______________ objects near the MRI machine or the magnet!
- The magnets are never off, even at night, and turning off the electrivity will not affect them.
- They draw most of their power from _________________, which must be vented (“quenched”) to shut down the magnet - a process that has hazards of its own and is very costly ( >$30,000 – 50,000).
ferromagneticmetal; supercooled helium
Potential difficulties in magenetic resonance imaging
Monitoring Failure in MRI
Computed (Axial) Tomography
- ACT Scan(orCAT Scan) is best suited for viewing:
- CT scans are widely used in emergency rooms because the scan takes fewer than ______ minutes.
- CT scans expose the patient to ________, which may be harmful if there are repeated exposures.
- bone injuries,
- diagnosing lung and chest problems, and
- detecting cancers
5;
radiation
Positron Emission Tomography
- A positron emission tomography (PET)scanis an imaging test that uses a ___________ called a tracer to look for disease or malignancy.
- Cells with increased ______ will absorb more of the radioactive tracer. A scanner then detects this substance to produce images of organs and tissues inside the body.
- radioactive substance
- metabolism
Same-Day Surgical Procedures
- _______ procedures that do not involve major violation of the body cavity.
- Procedures are typically limited in duration, generally less than _____ hours.
- They do not require ________beyond the capabilities of the parents or caregivers.
- Peripheral
- 2
- post discharge monitoring

Radiology
Dentistry
Considerations requiring 23-hour overnight observation (23 OBS)
- Ex-premature infants
- Obstructive sleep apnea (OSA)
- Distance from facility
- Ability of parents to care for child
Upper Respiratory Infections
Few issues in pediatric anesthesia have been as contentious as those regarding anesthesia for the child with an upper respiratory tract infection (URI).
The majority of complications in children with URIs are related to the presence of:
Specific complications include:
secretions and heightened airway reactivity.
Breath holding,
Airway obstruction,
Laryngospasm,
Bronchospasm and
Arterial oxygen desaturation.
Upper Respiratory Infections
- Studies show heightened airway reactivity in patients with URIs that may persist for up to _____ weeks following the infection.
- Viral infections are known to cause morphological and physiological pulmonary changes including, sloughing of the respiratory epithelium, altered ciliary beat frequency, and decreased airway conductance, forced vital capacity, functional residual capacity, and diffusion rates.
