Prone Positioning High Yield Users Guide
A lot of questions have come up around prone positioning in COVID19 patients. Click the button below for the high yield users guide our team created for Piedmont several years ago. It contains the key information such as when to prone, who to prone (inclusion/exclusion criteria), and when to stop.
Patients with COVID19 we are also occasionally asking them to “self-prone” that is prone while awake and not intubated which has some shown some good results throughout our hospitals thus far.
Background:
Prone position can significantly reduce mortality in Severe ARDS as proven by PROSEVA trial. The main points that they felt lead to their success:
Strict ARDSnet vent settings
Long prone sessions (16+ hours)
Focused on Severe ARDS patients (PF < 150)
Deep sedation and early paralytics encouraged
Waiting period from initial ABG to confirm true severe ARDS
Prone as a step in ARDS care and not done too late as a rescue therapy
Deciding to Prone:
Inclusion Criteria:
PF ratio < 150
Fio2 0.6 or greater
PEEP 5 or greater
VT at 6 cc/kg IBW
Protocol for initiation
Re-test ABG/PF ratio in 6 hours and begin prone position if remains < 150 and above vent settings still relevant
Call Rotoprone company at that time (done by RN): allow 2-3 hours for set up time and RN education
Exclusion Criteria
Intracranial pressure >30 mm Hg or cerebral perfusion pressure <60 mmHg if monitored
Massive hemoptysis requiring an immediate surgical or interventional radiology
Tracheal surgery or sternotomy during the previous 15 days
Serious facial trauma or facial surgery during the previous 15 days
Cardiac pacemaker inserted in the last 2 days
Unstable spine, femur, or pelvic fractures
Pregnant women
Lung transplantation
Burns on more than 20 % of the body surface
How to Order through the EPIC Order Set
Go to Epic Order Sets and Type in “prone” or “prone position”
Nurse and Respiratory Interventions will be prechecked as seen in screen shots below
CVL/Arterial line strongly encouraged to be placed if not already done so
Notes:
This includes a new RASS target of -5 (deep sedation) as opposed to standard RASS 0
Nursing will be utilizing their ventilator PAD order set for Propfol and Fentanyl gtt’s
Prone position for MINIMUM 16 hours prior to return to supine position
SBT/SAT done during patient’s time in the supine position
Will not receive either in prone position
May not qualify for SBT due to vent settings (Fio2 or PEEP)
Should attempt SAT after discussions with RN if felt patient reasonably able to return to RASS -5 for next prone session and depending on duration of supine position
Respiratory Interventions (All prechecked)
ABG’s will be done mutliple times throughout prone process (arterial line highly encouraged)
ARDS Vent Adjustment Guidelines
Prechecked standard ARDS net adjusment guidelines taken from current Piedmont RT guidelines
Nutrition Consult
Prechecked Nutrition consult to discuss nutrition plan for prone position
We are currently working with nutrition to design the best plan for these patients
There is no evidence based consensus on Pre vs Post-Pyloric feeding
There is no evidence based consensus on full feeds during prone position vs slow feeds vs no feeds (with corresponding increases during supine position)
Our recommendations:
Have nutrition calculate the total caloric daily needs and aim for those rather than a consistent rate
Slower feeds during prone position
Bolus feeds during supine position
Daily CXR
Paralytics
Paralytics are available but NEED to be checked if desired
Once checked they will automically check all 3 boxes below (bolus, infusion, monitoring)
Uncheck any that are not desired
Cisatracurium preferred paralytic in Severe ARDS prone positioning but others available
Important Points
When Utilizing Prone Position
Prone for minimum CONTINUOUS 16 hours at a time
No breaks during that time
Duration of prone position in days is continues until one of the following guidelines below for stopping has been met (PRECHECKED IN THE ORDER SET)
Criteria for STOPPING prone position (ONE OF THE FOLLOWING)
Improvement in Oxygenation
Defined as PF ratio > 150 WITH FIo2 < 0.6 AND PEEP < 10
Criteria must be met in SUPINE position > 4 hours after last prone session
RT will notify the provider if these criteria are met
Clinical Decline
Decrease in PF ratio by more than 20% in prone position relative to the ratio in the supine position
Needs to be seen in TWO consecutive prone sessions
Should not stop prone position due to decreased PF ratio in one session
RT will notify provider if these criteria are met
Complications occurring during a prone session or leading to interruption
Nonscheduled extubation
ETT Obstruction
Hemoptysis
O2 sat < 85% for > 5 mins while on 1.0 Fio2
PaO2 < 55 for while on 1.0 FIo2
Cardiac Arrest
Any life threatening event not otherwise defined
RN’s or RT’s will notify provider if any of these occur to stop prone positioning
Common Ventilator Adjustments
Vent settings while prone: think traditional ARDSnet
6 cc/kg IBW
PEEP off traditional PEEP/FIo2 table
Goal Pplat < 30
pH goal 7.25 – 7.45
If Pplat > 30
If breathing spontaneously; sedation increased to RASS -5, paralytic can be started if not already, paralytic bolused if already on
If still Pplat> 30; VT decreased by 1 ml/kg every 5 minutes as long a Pplat > 30 until 4 ml/kg.
If pH < 7.20 then VT not decreased
ABG timing
Baseline ABG prior to prone position
1 hour after prone position
Q6 hours during first prone session
Baseline supine ABG at 4 hours after return to supine
Life threatening criteria for IMMEDIATE prone positioning
PRONE as a true rescue therapy (immediate prone position, no waiting on repeat ABG)
PF ratio < 55
FIo2 1.0
Maximal PEEP according to PEEP/FIO2 table
Call rotoprone company immediately (or manual prone)
Call ECMO team as well to assess candidacy
Sedation
Sedation order set from adult ventilator management will be used with change in RASS to -5
RN’s will skip Fentanyl PRN boluses and start fentanyl/propofol gtt’s
Advanced Sedation order set available separately if unable to achieve RASS -5 with standard sedation
Daily spontaneously awakening and breathing trial ATTEMPTED while in supine position
Paralytics
Strongly recommended using paralytics within first 48 hours but ultimately up to provider discretion.
Nimbex preferred agent
PROVIDER NOTIFICATIONS TO BE AWARE OF
We will need to identify the patients with severe ARDS and assess prone position candidacy
Once order set written the following notifications will occur:
Repeat ABG in 6 hours and initiate the process of securing the prone bed
RN notification if unable to get RASS to -5 with currently ordered sedatives
Need for daily SAT/SBT
Best discussed on rounds with entire team (RN/RT/Intensivist)
Line placement if needed
Frequent ABG’s and ventilator adjustments
Nutrition discussion with RD’s
Use our recommendations above
RT’s will call if patient meets criteria for stopping prone positioning either due to clinical improvement, decline, or complication
