3 Objectives Discuss the physiologic rationale for the improvement in oxygenation and reduce lung injury with the prone position in patients with ARDS. Review the evidence to help determine whether to use the position in ARDS as front line therapy Identify evidence based strategies for determining when to turn, how long to remain prone and preventing airway and skin complications. Compare and contrast patient and staff advantages and disadvantages of various methods to position patients prone.

6 Why Prone Positioning in ARDSTo improve oxigenation during prone positioning and after repositioning supine (Langer, Chest 1988; Gattinoni, NEJM 2001) To improve the response to recruitment maneuvers during prone positioning (Pelosi, AJRCCM 2003, Oczenski, CCM 2005) To improve respiratory mechanics after repositioning supine (Pelosi, AJRCCM 1998) To reduce ventilator associated lung injury “per se” (Broccard, Crit Care Med ; Valenza, Crit Care Med 2005; Papazian, Crit Care Med 2005) To improve drainage of secretions (Pelosi, Eur Respir J 2002; Reignier, Intensive Care Med 2005)

23 Summary Prone: Supine: Increased FRC & improved complianceShifting of lung water & densities More homogenous aeration of the lung in ARDS from dorsal lung recruitment Increased oxygenation Supine: Marked reduction in lung volumes Alteration in lung mechanics (low compliance/high resistance) Compression atelectasis Hypoxemia

25 PERFUSION

26 Factors Influencing Regional Distribution of PerfusionCardiac output Pulmonary vascular resistance Gravity/body position

27 Distribution of PerfusionUpright Position: Blood flow decreases as it moves from base to apex with virtually little or no flow at the apices

28 J.B. West, C.T. Dollery, & A. Naimark, 1964, Journal of Applied Physiology, 19, p.71.3

29 Blood Flow Changes with PositionSupine position: Distribution becomes more uniform. Zone 3 maintained throughout the lung. Greater vertical perfusion gradient. Lateral position: Similar to supine except lung transforms to zone 2 approximately 18 cm above the most dependent part of the chest. Prone position: No major impact on regional distribution of pulmonary blood flow

30 Lung Protection in the Prone PositionAttenuate mechanical lung injury Improves dependent aeration recruiting alveoli Non-dependant regions shows dramatic reduction in hyperinflation Results in more homogenous lung aeration which reduces regional shear strain…less VILI Also decrease barotrauma and atelectrauma by recruiting and reducing over distension that occurs with higher PEEP Potential reduction in infection from drainage Scholten EL, et al.

58 How Well Are We Really Doing?Edited JA How Well Are We Really Doing? Every-2-Hour Turning So how well are we doing? There was a study done with 566 hours of observation over an 8-hour period, looking every 15 minutes to see how frequently patients got turned. What percentage of patients do you think got turned every 2 hours?

59 Body Position: Clinical Practice vs. StandardMulticenter study: 74 patients/566 total hours of observation Change in body position recorded every 15 minutes for 8hrs 2.7% had a q 2 hour body position change 49.3% of observed time no body position change Prospectively recorded, 2 days, 40 ICU’s in the UK Analysis on 393 sets of observations Average time between turns 4.85 hrs (3.3 SD) Krishnagopalan S.

60 Hemodynamic Instability Is it a Barrier to Positioning?

61 The Role of Hemodynamic Instability in Positioning1,2Lateral turn results in a 3%-9% decrease in SVO2, which takes 5-10 minutes to return to baseline Appears the act of turning has the greatest impact on any instability seen Minimize factors that contribute to imbalances in oxygen supply and demand Factors that put patients at risk for intolerance to positioning:3 Elderly Diabetes with neuropathy Prolonged bed rest Low hemoglobin and cardiovascular reserve Prolonged gravitational equilibrium One of the big concerns that we have is when a hemodynamically unstable patient is turned or early mobilization is used. A couple of practices that we routinely do that are not supported by science. One of them is that when we turn patients, we’re looking at all of the data on the monitor (the saturation and the blood pressure) and if we see that change, we immediately return the patient to the supine position. That isn’t supported by science. When we are laterally turning these patients, their hemodynamic variables do drop; it is expected. These patients require about 5 to 10 minutes of equilibration before they return to baseline. We shouldn’t be making our assessment until 5 to 10 minutes into the position turn or sitting up (because this also applies to dangling patients). We’re preventing progression to mobility because we’re not allowing this adaptation to occur. The other intervention that we can do to help is to minimize the factors that contribute to the oxygen supply-and-demand imbalance, because turning takes a fair amount of demand for the patient and that patient may not have the supply. By breaking up our care practices so the pateints have rest period in between they are more likely to tolerate activity. Winslow EH, et al. Heart Lung. 1990;19: Price P. Dynamics. 2006;17:12-19.

62 Has the manual position turn or HOB elevation been performed slowly?Decision-Making Tree for Patients Who Are Hemodynamically Unstable With Movement1,2 Screen for mobility readiness within 8 hrs of admission to ICU & daily initiate in-bed mobility strategies as soon as possible Is the patient hemodynamically unstable with manual turning? O2 saturation < 90% New onset cardiac arrhythmias or ischemia HR < 60 <120 MAP < 55 >140 SPB < 90 >180 New or increasing vasopressor infusion No Begin in-bed mobility techniques and progress out-of-bed mobility as the patient tolerates Yes No Is the patient still hemodynamically unstable after allowing minutes’ adaption post-position change before determining tolerance? Begin in-bed mobility techniques and progress out-of-bed mobility as the patient tolerates Yes No Screen for mobility readiness within 8 hrs of admission to ICU & daily initiate in-bed mobility strategies as soon as possible Allow the patient a minimum of 10 minutes of rest between activities, then try again to determine tolerance Here’s an algorithm that was recently published. If a patient is hemodynamically unstable with manual turning, this algorithm can help you determine what to do. You can start by waiting 5 to 10 minutes for the patient to equilibrate. If the patient is still experiencing issues, you can look at the mobility readiness. You can try manually turning, slowly, to see if the patient tolerates it. If not, the patient can be moved to rotational therapy. This algorithm is designed to ensure that no patient will remain hemodynamically unstable with manual turning or remain in a supine position for extended periods of time. Yes No Try the position turn or HOB maneuver slowly to allow adaption of cardiovascular response to the inner ear position change Has the manual position turn or HOB elevation been performed slowly? Yes Initiate continuous lateral rotation therapy via a protocol to train the patient to tolerate turning HOB=head of bed; HR=heart rate; MAP=mean arterial pressure; SPB=systolic blood pressure.

73 The How

74

75 Prone Positioning: The HowStep 2: Place the flat sheet around the arm that will pull through, (side you are turning toward). Turn towards the ventilator Step 1: With a flat sheet, pull the patient to side of bed opposite the ventilator using 4 staff.

76 Prone Positioning: The HowStep 4: Using the sheet turn the patient over toward the ventilator and position them prone. The arm and sheet will pull across the bed. Step 3: A second flat sheet is placed on the bed and tucked under the patient. This sheet will pull through as you are turning the patient.

77 Prone Positioning: The HowStep 5: Pull and center the patient. Discard the sheet that was used to supine patient. Straighten lines and tubes. Chest and/or pelvic support can be done by placing a pillow at the abdomen before completing the turn.

78 Returning to Supine: The HowStep 1: Using a flat sheet, pull the patient to one side of the bed. Step 2: Place the flat sheet around the arm that will pull through, (side you are turning toward). Step 3: A second flat sheet is placed on the bed and tucked under the patient. This sheet will pull through as you are turning the patient.

79 Returning to Supine: The HowStep 4: Using the sheet turn the patient over and position them supine. The arm and sheet will pull across the bed. Step 5: Discard the sheet that was used to supine patient (A). Straighten lines and tubes (B).

81 When to Stop Prone Positioning?In PROSEVA, prone positioning was stopped when PaO2/FiO2 remained > 150 mm Hg 4 h after supinating (with PEEP < 10 cm H2O and FiO2 < 0.6) Optimal strategy is unclear: consider continuing prone positioning until clear improvement in gas exchange, mechanics, and overall clinical course. Scholten EL, et al. Chest, 2017;151(1):

82 Positioning Schedule & Maintenance CareConsider every 16hrs uninterrupted (more freq turn back may cause decruitment) Maintain gain, laterally rotated/q2 turning until gas exchange decreases or no more than 2 hrs Loose gain, provide necessary care and return to the prone position Move head slightly every hour or q 2 If hemodynamic monitoring, level the zero reference point at the right atrium Vollman KM, Dickenson S, Powers J. AACN Procedural Manual, Chapter 19;2016:

83 Positioning Schedule & Maintenance CareROM of arms every 2 hours/change position of the arms Support feet in correct anatomical alignment Double secure endotracheal tube Eye care-if taping preform horizontal Turn off tube feeding 1hr prior to position change Consider time periods in reverse trendelenburg to address facial edema and reduce risk of vomiting Vollman KM, Dickenson S, Powers J.

86 Questions That Remain Optimal PEEP management in prone positionDoes effective prone positioning necessitate neuromuscular blockades for several days? What impact does that have on ICU acquired weakness? What is the learning curve and associated risk for inexperience centers adopting the practice Scholten EL, et al. Chest, 2017;151(1):

87 Definition of Progressive MobilityEarly Progressive Mobility definition: Planned movement in a sequential manner beginning at a patient’s current mobility status and returning the patient to baseline Early mobility includes: Head elevation Manual turning Passive and active range of motion Continuous lateral rotation therapy/prone positioning Movement against gravity Physiologic adaptation to an upright/leg down position (Tilt Table, bed egress) Chair position Dangling Ambulation The definition of early mobility is “planned movement in a sequential manner beginning at a patient’s current mobility status and returning the patient to baseline.” This definition includes all types of mobility, from head-of-bed (HOB) elevation (which can not only prevent aspiration, but can also begin to help the patient physiologically adapt to an upright position), to manual turning in the bed, to passive and active range of motion (ROM), rotational therapy (if needed), using the bed as a Tilt Table for that physiological adaptation, in-bed and out-of-bed chair position, dangling, and ambulation. It covers a full spectrum of mobilization. Vollman KM. Crit Care Nurse. 2010;30:S3-S5.
