ICU Boarder

✓ Analgesia & Sedation

✓ Mechanical Ventilation

Pain & Anxiety• Critically ill patients experience pain

✓ Mechanical ventilation (ETT, LPV, etc)

✓ Invasive procedures

✓ Surgical procedures

✓ Nursing care (suctioning, repositioning)

Pain & Anxiety• Critically ill patients unable to report pain

✓ Altered mental status

✓ Mechanical ventilation

✓ Sedative and NMBA medications

Pain & Anxiety• Rotondi, et al. Crit Care Med 2002

✓ 82% remembered pain with ETT

• Gelinas, et al. Intensive Crit Care Nurse 2007

✓ 77% remembered pain during ICU stay

• Chanques, et al. Anesthesiology 2007

Ayasrah SM. J Crit Care. 2019

Pain & Anxiety• Short-term consequences

✓ Increase catecholamines

✓ Arteriolar vasoconstriction

✓ Impair tissue perfusion

✓ Increase myocardial oxygen consumption

Pain & Anxiety• Long-term consequences

✓ PTSD

✓ Post-ICU Syndrome

✓ Depression

✓ Family / Caregivers

Pain & Anxiety✓ Providers consistently under rate and

under treat pain in the critically ill

Devlin, et al. Crit Care Med. 2018

• “Suggest an assessment-driven, protocol-based, stepwise approach for pain management”

• Use validated protocols

• Analgosedation or analgesia-based sedation


Pain Assessment

Vital signs are inadequate!

Pain Assessment• Validated Protocols

✓ Shorter duration of mechanical ventilation

✓ Reduced ICU LOS

✓ Reduced sedative requirements

✓ Reduced medication side effects

Pain Assessment✓ Numeric Rating Scale

✓ Behavior Pain Scale

✓ Critical Care Pain Observation Tool

✓ Visual Analog Scale

• “Suggest an assessment-driven, protocol-based, stepwise approach for pain management”

• Use validated protocols

• Analgosedation or analgesia-based sedation


• Retrospective cohort

• Single center MICU

• Evaluate impact of an analgosedation protocol

Faust, et al. Anesth Analg 2016

• Control Group

✓ Sedative: propofol

✓ Analgesics administered second (morphine)


• Intervention Group

✓ Revised protocol

✓ Analgesics first (fentanyl)

✓ Sedative: propofol or dexmedetomidine as needed


• Results - Intervention Group

✓ Improved pain control

✓ Reduced sedative infusion by 54%

✓ Decreased duration of mechanical ventilation


Pain Treatment• Opioids are first-line analgesics

✓ Fentanyl

✓ Morphine

✓ Hydromorphone

✓ Remifentanil

Pain Treatment• Adjuvants to Opioids

✓ Ketamine

✓ Acetaminophen

✓ Neuropathic pain meds

• Lidocaine

• NSAIDS

Analgesia✓ Vital signs alone are inadequate

✓ Implement protocols (BPS, CPOT)

✓ Start with analgesics (opioids)

✓ Consider adjuvants to opioids

Agitation• Associated with adverse outcomes

• Consequences of prolonged, deep sedation

✓ Increased duration of mechanical ventilation

✓ Increased ICU LOS

• Secondary analysis of prospective cohort

• Single, tertiary, academic center

• Assess relationship b/w ED sedation depth and outcome

Stephens RJ, et al. Chest 2017

• Results - 414 patients

✓ 14.3% received no analgesic

✓ 15.2% received no sedation


• Results - Outcome

✓ Median RASS (-3)

✓ Deep sedation occurred in 64%

✓ Deeper ED RASS associated with increased hospital mortality (aOR 0.77)


• Multicenter, prospective cohort study

• EDs and ICUs of 15 medical centers

• Characterize ED sedation practices and test hypothesis that deep sedation is associated with worse outcomes

Fuller, et al. Crit Care Med. 2019

• Results - 324 Patients

✓ Deep ED sedation: 171 (53%)

✓ Light ED sedation: 153


• Results - 324 Patients

✓ 28.4% given no analgesia

✓ 21.3% given no sedation

✓ 10.8% given no ED analgesics or sedatives


• Results - Depth of Sedation

✓ Patients exposed to deep sedation had higher frequency of deep sedation on ICU day 1 and day 2

✓ Median RASS during first 24 hrs in ICU: -3


• Systematic review and meta-analysis

• Impact of deep sedation within 48 hours of initiation of mechanical ventilation

Stephens, et al. Crit Care Med. 2018

• 4,521 Patients (9 Studies)

✓ Early, light sedation associated with lower mortality vs. deep sedation (9.2% vs. 27.6%)

✓ Early, light sedation associated with fewer mechanical ventilation days (-2.1 days)

Stephens, et al. Crit Care Med. 2018

• “Suggest using light sedation in critically ill mechanically ventilated adults”

• No universally accepted definition of light sedation

• Most use RASS -2 to +1


Agitation Assessment• Richmond Agitation-Sedation Scale

• Sedation-Agitation Scale

• Ramsay Sedation Scale

• Sedation Intensive Care Score

• New Sheffield Sedation Scale

• “Suggest using either propofol or dexmedetomidine over benzodiazepines”

• Most studies benzodiazepines given as continuous infusion


Sedation✓ Early sedation depth may be associated

with increased mortality

✓ Target lighter levels of sedation

✓ RASS -2 to +1

✓ Propofol or dexmedetomidine

✓ Minimize benzodiazepine use

• Survey of academic EM attendings

• 7 academic hospitals in the Northeast

• Most receive ≤ 3 hrs of MV education a year

Wilcox SR, et al. West J Emerg Med 2016

• Prospective, observational study

• 4 academic EDs

• Further characterize ED mechanical ventilation practices

Fuller, et al. Chest 2015

• 219 patients

✓ LPV used in only 56%

✓ 11% ventilated with Vt > 10 ml/kg PBW

Fuller, et al. Chest 2015

• Prospective observational cohort 525 pts

• 3 academic EDs

• Is longer duration of ED MV associated with in-hospital mortality, duration of mechanical ventilation, LOS?

Angotti LB, et al. West J Emerg Med 2017

• 64 Patients Ventilated > 7 hours

✓ Higher in-hospital mortality (45.9% vs. 29.4%)

✓ Longer duration of MV (4.8 days vs. 2.5 days)

✓ Less likely to have changes in ventilator settings during ED time

Angotti LB, et al. West J Emerg Med 2017

LPV✓ Tidal volume: 6-8 ml/kg IBW

✓ Permissive hypercapnia

✓ Reduce FiO2 as soon as possible

✓ Pplat: < 30 cm H2O

• Quasi-experimental study

• ED / ICU of academic, tertiary care center

• Evaluate the effectiveness of an ED-based lung-protective mechanical ventilation protocol on pulmonary complications

Fuller, et al. Ann Emerg Med 2017

• Intervention

✓ Tape measure for accurate height

✓ Tidal volume: 6 ml/kg PBW

✓ Limit plateau pressure < 30 cm H2O

✓ Titrate FiO2 (SpO2 90-95%)

✓ Elevate HOB


• Results - ED

✓ LPV increased by 48.4%

✓ Tidal volume decreased by 1.8 ml/kg PBW


• Results - ICU

✓ LPV increased by 30.7%

✓ Tidal volume decreased by 1.1 ml/kg PBW

✓ Decreased ICU and hospital LOS

✓ Mortality: 14.5% absolute risk reduction


Mechanical Ventilation• ED Ventilator Settings Matter!



✓ Decrease FiO2 (SpO2 90-95%)

✓ Elevate HOB

✓ Measure plateau pressure

Ventilator Pressures• Peak Pressure

✓ Reflects pressure from airflow resistance and respiratory system compliance

✓ Measure during inspiratory flow

Ventilator Pressures• Plateau Pressure

✓ Reflects static respiratory system compliance

✓ Better marker of overdistention (volutrauma)

✓ Measure with end-inspiratory hold in a passive patient

✓ Goal < 30 cm H2O

High Peak +Normal Plateau

• Increased airway resistance (bronchospasm)

• Kinked or twisted ETT

• ETT obstruction (secretions)

Wood S, et al. EM Critical Care 2013

•Intrathoracic

✓ ARDS, Pneumonia

✓ Pulmonary edema
