6. Hello..hello ...
Who are you..?
A trained anesthesiologist should provide anaesthesia in
remote locations within the hospital.
However non anesthesiologists are allowed to
provide ‘conscious sedation'.
It is mandatory that all providers should be
Adult Cardiac Life Support (ACLS) certified.
7. Preparations

13. Guidelines for PADIS 2018 SCCM
Ungraded statement:
Self-report scales:
A patient’s self-report of pain is the reference standard for pain assessment in
patients who can communicate reliably. Among critically ill adults who are able
to self-report pain, the 0–10 numeric rating scale administered either verbally or
visually is a valid and feasible pain scale.
Behavioral pain assessment tools:
Among critically ill adults unable to self-report pain and in whom behaviors are
observable, the BPS and BPS-NI patients and the CPOT demonstrate the greatest
validity and reliability for monitoring pain.
16. Potential Benefits with Protocolized
ICU Pain Assessment
A higher degree of pain assessment with a validated tool
via protocol (and education) is associated with:
Improved pain scores.
Length of ventilation and ICU stay.
Mortality.
Consumption of sedatives.
Need for opioids in non communicative pts.
Use of non-opioid analgesics.
Opioid related adverse drug events (ORADE).

17. Guidelines for PADIS 2018 SCCM
Good Practice Statement.
Management of pain for adult ICU patients should be
guided by routine pain assessment and pain should be
treated before a sedative agent is considered.
Recommendation:
We suggest using an assessment-driven, protocol based,
stepwise approach for pain and sedation management in
critically ill adults. CONDITIONAL recommendation, MODERATE quality of evidence.
19. FENTANYL
Since fentanyl does not cause histamine release the
SCCM/ACCM recommend fentanyl for analgesia in the
haemodynamically unstable patient.
REMIFENTANIL
The short duration of action is B/C it is broken down by
nonspecific esterases in plasma. So dose adjustments are
not necessary in renal or hepatic failure.
Its unique characteristics make it suitable for patients in
whom pain is a limitation for weaning.
Recommendation:
We suggest using an opioid, at the lowest effective dose,
for procedural pain management in critically ill adults.
CONDITIONAL recommendation MODERATE quality of evidence.
20. Recommendation:
We suggest using acetaminophen as an adjunct to an
opioid to decrease pain intensity and opioid
consumption for pain management in critically ill adults.
CONDITIONAL recommendation, VERY LOW quality of evidence.
We suggest using low-dose ketamine (0.5 mg/kg IVP x 1
;1–2 μg/kg/hr) as an adjunct to opioid therapy when
seeking to reduce opioid consumption in post-surgical
adults admitted to the ICU. CONDITIONAL recommendation, VERY LOW
quality of evidence.
21. Recommendation:
We recommend using a neuropathic pain medication
(e.g. gabapentin, carbamazepine, and pregabalin) with
opioids for neuropathic pain management in critically ill
adults. STRONG recommendation, MODERATE quality of evidence.
We suggest using a neuropathic pain medication (e.g.,
gabapentin, carbamazepine, and pregabalin) with
opioids for pain management in ICU adults after
cardiovascular surgery. CONDITIONAL recommendation, LOW quality of
evidence.
Adjunctive Neuropathic
Pain Medications
22. Recommendation:
We suggest not routinely using IV lidocaine as an
adjunct to opioid therapy for pain management in
critically ill adults. CONDITIONAL recommendation, LOW quality of evidence.
We suggest not using either local analgesia or nitrous
oxide for pain management during chest tube removal in
critically ill adults. CONDITIONAL recommendation, LOW quality of evidence.
We recommend not using inhaled volatile anesthetics
for procedural pain management in critically ill adults.
STRONG recommendation, VERY LOW quality of evidence.
23. Recommendation:
We suggest using an NSAID administered intravenously,
orally or rectally as an alternative to opioids for pain
management during discrete and infrequent procedures
in critically ill adults CONDITIONAL recommendation, LOW quality of evidence
We suggest not using an NSAID topical gel for
procedural pain management in critically ill adults
CONDITIONAL recommendation, LOW quality of evidence).
NSAIDs
Only three drugs: acetaminophen, ketorolac, and
ibuprofen are used primarily for pain control in the
early postoperative period. combination with an
opioid analgesic for moderate-to-severe pain.
24. Recommendation:
We suggest offering massage for pain management in
critically ill adults. CONDITIONAL recommendation, LOW quality of evidence.
We suggest offering music therapy to relieve both
nonprocedural and procedural pain in critically ill adults.
CONDITIONAL recommendation, LOW quality of evidence.
We suggest offering cold therapy for procedural pain
management in critically ill adults. CONDITIONAL recommendation,
LOW quality of evidence.
Remarks: Cold ice packs were applied for 10 min, and wrapped in dressing
gauze, on the area around the chest tube before its removal.
We suggest offering relaxation techniques for
procedural pain management in critically ill adults.
CONDITIONAL recommendation, VERY LOW quality of evidence.
25. Agitation
“A syndrome of excessive motor activity, usually non-
purposeful and associated with internal tension.”
Observed in as many as 85% of patients in the ICU.

27. Respiratory Depression and
Oversedation
30% respiratory depressions due to sedation:
> 50% of GI suite cases.
70% of radiology cases.
Only 15% of these cases used capnography.
92% of cases resulted in death or severe hypoxic
brain injury.

29. Light Versus Deep Sedation
RAAS (-2 to +1)
Time to extubation Associated with shorter time.
Tracheostomy rate Reduced.
90 days mortality Not significant.
Light sedation was not associated with reduction in:
Delirium (2 RCTs, 140 patients), RR 0.96 (95% CI, 0.80 to 1.16).
PTSD (2 RCTs, 62 patients), RR 0.67 (95% CI, 0.12 to 3.79).
Depression (2 RCTs, 128 patients), RR 0.76 (95% CI, 0.10 to 5.58).
Recommendation:
We suggest using light vs. deep sedation in critically
ill, mechanically ventilated adults.
CONDITIONAL recommendation, LOW quality of evidence.
30. Daily Sedation Interruption Decreases Duration
of Mechanical Ventilation
Hold sedation infusion until
patient awake and then
restart at 50% of the prior
dose.
“Awake” defined as 3 of the
following 4:
1. Open eyes in response to
voice.
2. Use eyes to follow
investigator on request.
3. Squeeze hand on request.
4. Stick out tongue on request.
Kress JP, et al. N Engl J Med. 2000;342:1471-1477.
Effect of this strategy on outcomes:
One- to seven-day reduction in length of sedation and MV need.
50% reduction in tracheostomies.
Three-fold reduction in the need for diagnostic evaluation of CNS.
32. Choose the Right Drug
Sedation
Amnesia
Benzodiazepines
Analgesia
AnxiolysisHypnosis
Diazpam, Midazolam and Lorazepam
33. Advantages:
Benzodiazepines have a dose-dependent amnestic
effect (antegrade amnesia).
Benzodiazepines have anticonvulsant effects.
Benzodiazepines are the sedatives of choice for drug
withdrawal syndromes including alcohol, opiate, and
benzodiazepine withdrawal.
Disadvantages:
A. NO analgesia.
B. Drug accumulation with prolonged sedation.
C. The apparent tendency for BZD to promote delirium.
D. Dose dependent respiratory depression.
Benzodiazepines
Midazolam
34. Choose the Right Drug
Sedation Analgesia
Amnesia AnxiolysisHypnosis
Propofol
35. Clinical Effects: Adverse Effects:
Propofol
Sedation.
Hypnosis.
Anxiolysis
Muscle relaxation.
Mild bronchodilation.
Decreased ICP.
Decreased cerebral
metabolic rate.
Antiemetic.
Pain on injection.
Respiratory depression.
Hypotension.
Decreased myocardial
contractility.
Increased serum triglycerides
Tolerance.
Propofol infusion syndrome.
Prolonged effect with high
adiposity.
Not analgesia!
Can be used for intractable seizures and elevated ICP.
Don’t give Propofol >4mg/kg/h for >7 days.
36. Ketamine
Acts by stimulation of NMDA receptors.
Provides analgesia + amnestic + sedative effects.
Preserves respiratory drive - "awake" intubation.
Bronchodilator – used to treat severe acute asthma.
Beneficial effects on stunned myocardium.
Ketamine 0.5 – 1 mg / kg / hour in Refractory S E.
Generally not used because Releases catecholamine's –
Positive inotropic, Induce VC, Inhibits end NO
myocardial O2 demand and intracranial pressure (ICP).
Produces nightmares so combine with benzodiazepines.
INDICATION: Intubation in SHOCK and ASTHAMA.
37. Dexmedetomidine
Has been shown to decrease the need for other sedation in
postoperative ICU patients.
Benefits:
Does not cause respiratory depression.
Short- acting Sedation, Analgesia and Anxiolysis.
Produces sympatholysis which may be advantagous
in certain patients such as postoperative cardiac surgery.
Risks:
No amnesia.
Small number of patients reported distress upon
recollection of ICU period despite good sedation
scores due to excessive awareness.
Bradycardia and hypotension can be excessive,
necessitating drug cessation and other intervention.
Can be used for sedation in both spontaneous
and mechanically ventilated patients.
45. 1) Sedation, Analgesia & Paralytics are not a
treatment.
Its just an adjunctive therapy.
3) Use right medications, right dose according to
condition of patients.
It should be confirm by prescribing doctor.
2) Never use Paralytics without sedation &
Analgesia.
Same way never use sedation without analgesia.
46. 4) Dex + Propofol + Cis-Atra ideal combination
but with limitations.
Increase use of Dex & Cis-Atra
Avoid Midazolam as much as possible.
5) Label over infusion pump about medicine,
dosage and preparations.
47. Summary
Patients must be assessed before moderate sedation.
Sedation options and risks must be discussed with the
patient and family prior to the procedure.
Moderate sedation must be given by a qualified
provider.
Patients must be monitored during sedation.
Protocol for Pain, Agitation & Delirium Scoring
systems.
Adequate analgesia for procedures.
Light sedation is ass with improved clinical outcomes.
Daily sedation interruption.
Use non-benzodiazepine sedative.
