- Vignette: Respiratory Failure- it hurts to breathe | Doc on the Run
< Back Respiratory Failure- it hurts to breathe A 47-year-old male sustains multiple traumatic injuries after being struck by a vehicle while on the side of the road. He had severe thoracic trauma (bilateral pulmonary contusions), bilateral femur fractures and a liver laceration. He also had a severe TBI, requring intubation shortly after his arrival. 10 days into his hospital stay, he still requires ventilatory support. What are some of the potential causes of the patients ongoing requirement for mechanical ventilatory support? Pain from rib fractures, pneumonia, ARDS, pulmonary embolism, fat embolism, pulmonary contusions, loss of chest wall stability due to severe thoracic trauma, hypomagnesemia, volume overload, retained hemothorax, poor nutrition from inadequate protein delivery. He is undergoing a trial of spontaneous ventilation, but he develops tachypnea and hypoxemia and appears to be struggling on the ventilator. What are some of the initial steps in evaluating this patient? Physical exam (pulmonary exam, assess for edema), bedside ultrasound (pleural effusion, pneumothorax). Chest x-ray- look for infiltrates. ABG, EKG, review volume status. His chest x-ray is shown below. What do you see? Trachea midline, no effusions. Bilateral fluffy infiltrates. His current ventilator settings and ABG results are shown below. Ventilator settings: RR 12, TV 450, PEEP 10, FiO2 50. Arterial blood gas: pH 7.34, PaCO2 42, PaO2 64, HCO3 24 What does this tell you about his oxygenation? PaO2:FiO2 ratio is an indicator of oxygenation. This patients P:F ratio is 182. See below for explanation. What diagnosis is this consistent with? Acute respiratory distress syndrome. What are the management principles when caring for a patient with ARDS? What are your initial ventilator management strategies? ARDS is not a primary diagnosis, so it is important to treat the underlying cause (pancreatitis, pneumonia, etc). Minimize further insults to the lungs. Optimize ventilator strategies- low tidal volume, target PEEP/FiO2 combination to target SpO2 88-95% Diagnosis and Management of ARDS Etiologies of ARDS Pneumonia, pulmonary contusions, aspiration, inhalation Trauma, burn Pancreatitis Transfusion-related acute lung injury (TRALI) ARDS diagnostic criteria: The Berlin Definition [1] Onset of respiratory failure within 1 week of an insult that is known to cause ARDS Bilateral fluffy infiltrates on CXR not explained by effusions/ infiltrates/ contusions/ lung collapse Respiratory failure not related to heart failure or fluid overload Oxygenation PaO2/FiO2 ratio with PEEP ≥5 cm H2O. Mild 200-300, moderate 100-200, severe ≤100. Basic principles of ARDS management [2,3] Low tidal volume ventilation- 4-8 mL/kg predicted body weight. Prevent volutrauma. Permissive hypercapnia- low TV ventilation leads to decreased minute ventilation, which leads to CO2 retention (hypercapnia). Hypercapnia is tolerated as long as pH remains above 7.2. Positive end-expiratory pressure (PEEP)- goal is avoiding overdistension and optimizing recruitment If ↑PEEP→ ↓plateau pressure: recruitmentIf ↑PEEP→ ↑plateau pressure: overdistension Optimizing mean airway pressure (MAP). Prolonged inspiratory:expiratory ratio Target plateau pressure <30, driving pressure ≤15. Recruitment manuevers Advanced strategies for persistent hypoxemia Prone positioning Airway Pressure Release Ventilation (APRV) Neuromuscular blockade Inhaled vasodilators Prostacyclin and nitric oxide ECMO High frequency oscillatory ventilation Open lung ventilation Dexamethasone Extracorporeal carbon dioxide removal (ECCO2R) References Ferguson ND et al.

13 Maybe you Should Talk to Someone A Therapist, HER Therapist, and Our Lives Revealed Some of my favorite quotes Peace. It does not mean to be in a place where there is no noise, trouble or hard work. It means to be in the midst of these things and still be calm in your heart. (p. 289). HMH Books. Kindle Edition. “Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom. (p. 289). HMH Books. Kindle Edition. Which is why, in the end, after several drafts and revisions, Julie decided to keep her obituary simple: “For every single day of her thirty-five years,” she wanted it to read, “Julie Callahan Blue was loved.” Love wins.

- Book Review: Everybody Lies | Doc on the Run
3 Everybody Lies Big Data, New Data, and What the Internet Can Tell Us About Who We Really Are - The staggering amount of data available and the power to make predictions. - Internet search bars have entered society as a secret place to ask our most urgent/ personal/ embarrassing questions without risk of guilt or shame from others discovering intimate details about us. People lie on job interviews, online surveys, and almost anywhere they are at risk of being revealed, which introduces a significant bias in database queries. In contrast, there is no motivation to lie to the anonymous search bar. - Evaluating internet searches can reveal an infinite amount of information about society as a whole. Monitoring internet searches during presidential addresses, evaluating searches for unemployment offices, what to say on first dates- there is so much data that can be harnessed to understand society.

- Before Surgery | Doc on the Run
< Back Before Surgery American College of Surgeons (ACS) Operation Brochures for Patients Patient Education: Preparing for Your Surgery How Can I Be Strong for Surgery? Strong for Surgery is a program that works with surgeons and hospitals to provide tools like checklists that surgeons can use to assess your risks in four target areas: nutrition, blood sugar control, smoking cessation, and medications. You can lower your risk by being better prepared for your operation. NSQIP Surgical Risk Calculator Disclaimer: The ACS NSQIP Surgical Risk Calculator estimates the chance of an unfavorable outcome (such as a complication or death) after surgery. The risk is estimated based upon information the patient gives to the healthcare provider about prior health history. The estimates are calculated using data from a large number of patients who had a surgical procedure similar to the one the patient may have. Previous Next
- Tutorial: Vent Mgmt #5: Weaning | Doc on the Run
< Back Vent Mgmt #5: Weaning When is the patient ready to start ventilator weaning? Resolution of pathology resulting in the need for mechanical ventilation Able to assess mental status (ie can the patient follow commands) Hemodynamics and respiratory physiology is optimized (ie ABG normalized or returned to patients baseline, and normalization or stabilization of cardiac function) Minimal ventilator settings (FiO2 21%, PEEP 5) NOTE: Even if there is no immediate plan to extubate, sedation holiday and spontaneous breathing trials should still be performed [unless there are specific contraindications] Spontaneous breathing trial Spontaneous mode of ventilation (such as pressure support or CPAP) with 5-8 cm H2O support during inspiration (basically overcoming the force required to breath through the small diameter of the ETT) Failing SBT Hemodynamic instability (hypotension or hypertension, tachycardia or bradycardia) Agitation Respiratory instability (hypoxia, inadequate tidal volume, tachypnea or decreased respiratory rate) Extubation parameters- how do we know if the patient is ready to be liberated from the ventilator? Able to generate adequate minute ventilation Rapid shallow breathing index (RSBI)- RR/ TV. High respiratory rate (rapid) and low tidal volume (shallow) are more suggestive that a patient isn't appropriate for extubation. Value <105 suggests the patient will successfully extubate. This is also known as the Tobin index.[1] Negative inspiratory force (NIF)- the patient's ability to generate negative pressure with inhalation. Cuff leak- ability to move air around the endotracheal tube. Not mandatory to evaluate for cuff leak prior to extubate EXCEPT for patients is at high risk for airway edema (traumatic intubation, intubated >6 days, large ETT, female, reintubation after unplanned extubation). Reasons for failed ventilator weaning Prolonged hospitalization and associated weakness Hypophosphatemia Primary process requiring mechanical ventilation is unresolved Passed SBT...but failed ventilator liberation? Excess secretions/ inability to cough Cardiac instability related to physiological changes with loss of positive pressure (specifically decrease in intra-thoracic pressure leading to decreased cardiac output) Tobin Index.
