PROCEDURAL SEDATION Flashcards
SEDATION
CONTROLLED REDUCTION IN AWARENESS OF ENVIRONMENT
ANXIOLYSIS
MILD SEDATION
STATE OF REDUCED APPREHENSION
-RESPOND NORMALLY TO VERBAL STIMULI
- CO-ORDINATION / COGNITION MAYBE IMPAIRED
-CARDIORESPIRATORY FUNCTIONS INTACT
DISSOCIATIVE ANALGESIA
EG/ KETAMINE
TRANCE LIKE CATALEPTIC STATE - WITH ANALGESIA AND AMNESIA
MODERATE SEDATION
- RESPONDS PURPOSEFULLY TO VERBAL + /- TACTILE STIMULI
-CARDIORESPIRATORY FUNCTIONS INTACT - CONSCIOUS SEDATION
DEEP SEDATION
- RESPONDS PURPOSEFULLY TO PAINFUL STIMULI
- NOT EASILY AROUSABLE
- RESPIRATORY FUNCTIONS MAYBE IMPAIRED
-CARDIAC FNS INTACT
GENERAL ANASTHESIA
CARIORESPIRATORY FNS NOT INTACT
NOT AROUSABLE
PROCEDUAL SEDATION
USING A SEDATIVE/DISSOCIATIVE AGENT +/_ ANALGESIA TO MAKE UNPLEASANT PROCEDURES TOLERABLE
SOAPME
- SUCTION
-OXYGEN
-AIRWAY
-PHARMACY/ POSITION
-MONITOR / MEDS
-EQUIPEMNT
WHEN IS MAX RISK OF DETERIORATION
WHEN THE PAINFUL STIMULI IS REMOVED
ASA CLASSIFICATION
1 - NO CO-MORB
2- MILD SYSTEMIC DISSEASE WITHOUT FUNCTIONAL LIMITATION
3- SEVERE SYSTEMIC DISEASE WITH FUNCTIONAL LIMITAION
4- DISEASE WITH CONSTANT THREAT TO LIFE
5- MORIBUND MAYNOT SURVIVE WITHOUT PROCEDURE
PREPROCEDURAL FASTING
- NOT REQUIRED
- MAYNOT REDUCE EMESIS OR ASPIRATION
OXYGEN SUPPORT
- MAY CAUSE DELAYED DETECTION OF HYPOVENTILLATIONOR APNEA
-USE CAPNOGRAPHY
BIS
- NOT USED IN INFANTS
- DEPTH OF SEDATION (EFFECT OF DRUG ON CORTEX RATHER THAN CONSCIOUSNESS IS ASESSED)
-0-100
-40-60 FOR GA
PROPOFOL ADVANTAGE
-ANTIEMETIC
-SHORT ACTIMG
-RAPID ONSET
PROPOFOL DISADVANTAGE
-HYPOTENSION
-RESPIRATORY DEPRESSION
PROPOFOL DOSE
1-1.5 MGKG
INCREMENTS OF 0.5 MG/KG
ADVANTAGE OF KETAMINE
1.SEDATION (DISOOCIATIVE)
2.AMNESIA
3. ANALGESIA
4 MANITAIN CARDIORESPIRATORY FN
-PROTECTIVE AIRWAY REFLEX
-SPONT RESPIRATION
-INCREASE BP
-INCREASE HR/CO
-MYOCARDIAL O2 CONSUMPTION INCREASED
-BRONCHODIALATION
DISADVANTAGE OF KETAMINE
- APNEA
- LARYNGOSPASM (MAYBE RELIEVED BY REPOSTION, PPV, O2 , 10% NMB)
3.EMESIS - EMERGENCE REACTION (MIDAZOLAM 0.03 MG/KG)
- INCREASED SALIVATION (GLYCOPYROLATE)
GLYCOPYROLATE OVER ATROPINE
- LESS ARRYTHMIA
- BETTER SIALAGOGUE
- DONOT CROSS BBB
MAY CAUSE HEADACHE
EMERGENCE REACTION AKA
RECOVERY AGITATION
EMESIS WITH KETAMINE SEEN IN
HIGH DOSE / IM
KETAMINE DOSE
1-2 MG/KG IV (0.5- 1 MG/K ALLOQUITE)
4-5 MG/KG IM
5-7 MG/KG PO
KETOFOL DOSE
0.5-0.75 MG/KG BOTH
1:1 IN SYRINGE
REPAEAT PROPOFOL 0.1-0.5 MG/KG SOS
KETOFOL ADVANTAGE
- HR/BP MAINTAINED BY KETAMINE
- ANALGESIA BY KETAMINE
- ANIT EMETIC BY PROPOFOL
-DECREASED DOSE OF DRUG
