Abstract

Carbon monoxide (CO) is the most common cause of poisoning and poisoning-related death in the United States. It is a tasteless and odorless poisonous gas produced from incomplete combustion of hydrocarbons, such as those produced by cars and heating systems. CO rapidly binds to hemoglobin to form carboxyhemoglobin, leading to tissue hypoxia, multiple-organ failure, and cardiovascular collapse. CO also binds to myocardial myoglobin, preventing oxidative phosphorylation in cardiac mitochondria and resulting in cardiac ischemia or stunning and cardiogenic pulmonary edema. Treatment of CO poisoning is mainly supportive, and supplemental oxygen remains the cornerstone of therapy, whereas hyperbaric oxygen therapy is considered for patients with evidence of neurological and myocardial injury. Extracorporeal membrane oxygenation (ECMO) has been utilized effectively in patients with respiratory failure and hemodynamic instability, but its use has rarely been reported in patients with CO poisoning. We report the successful use of venoarterial ECMO in a patient with severe CO poisoning and multiple-organ failure.

Introduction

Carbon monoxide (CO) is the most common cause of poisoning and poisoning-related death, resulting in > 20,000 emergency department visits and ∼450 fatalities each year in the United States.1 CO is a tasteless and odorless poisonous gas produced from incomplete combustion of hydrocarbons, and it is found in combustion fumes, such as those produced by cars and trucks, small gasoline engines, stoves, lanterns, burning charcoal and wood, gas ranges, and heating systems. CO rapidly binds to hemoglobin to form carboxyhemoglobin, leading to tissue hypoxia, multiple-organ failure, and cardiovascular collapse.2 CO also binds to myocardial myoglobin, preventing oxidative phosphorylation in cardiac mitochondria and resulting in cardiac ischemia or stunning and cardiogenic pulmonary edema.3 Treatment of CO poisoning is mainly supportive, and supplemental oxygen remains the cornerstone of therapy, whereas hyperbaric oxygen therapy is considered for patients with evidence of neurological and myocardial injury. We present a patient who developed multiple-organ failure associated with CO poisoning and who was successfully supported with venoarterial extracorporeal membrane oxygenation (ECMO).

Case Report

A previously healthy 38-y-old woman was found unresponsive in a recreational vehicle while camping in the fall. She was emergently intubated, treated with oxygen (FIO2 of 1.0), and transferred to a tertiary center for suspected CO poisoning associated with malfunction of the vehicle's exhaust system. The duration and intensity of CO exposure were not known, but the patient's husband was found dead in the same vehicle, and witnesses described them as having good health 10 h before discovery. Her initial vital signs showed a heart rate of 134 beats/min and blood pressure of 87/54 mm Hg. Laboratory results revealed severe anion gap metabolic acidosis with a serum lactate level of 7.6 mmol/L and a carboxyhemoglobin level of 13.6% (∼2–4 h after being placed on FIO2 of 1.0). A urine drug screen, human immunodeficiency virus, alcohol, and salicylate levels were negative. The baseline blood count, chemistry profile, liver function test, and electrocardiography were normal. Brain computed tomography was negative for intracranial pathology or cerebral edema. Chest radiograph showed bilateral air space opacities. Arterial blood gas analysis showed a pH of 7.15, a PaCO2 of 25 mm Hg, and a PaO2 of 73 mm Hg at an FIO2 of 1.0 (Table 1). The patient received supportive care with volume control ventilation (tidal volume of 6 mL/kg of ideal body weight) and required an increased breathing frequency (35 breaths/min), PEEP (16 cm H2O), and FIO2 of 1.0 (peak airway pressure of 42 cm H2O). Despite fluid resuscitation, she developed refractory shock, required multiple vasoactive agents, and was too unstable to be transferred to a hyperbaric chamber.

Interventions, Laboratory Values, and Parameters from Mechanical Ventilation and ECMO

Over the next few hours, the patient developed refractory hypoxemia (pH 7.23, PaCO2 of 38 mm Hg, PaO2 of 54 mm Hg with FIO2 of 1.0) and progressed to multiple-organ failure, including myocardial ischemia with left-ventricular dysfunction (troponin level of 47 ng/mL), metabolic acidosis (lactate level of 11 mmol/L), cardiogenic pulmonary edema, rhabdomyolysis (creatine kinase level of 2,887 units/L, peak at 6 h after presentation), severe coagulopathy (prothrombin time of 36.4 s, international normalized ratio of 3.97, prothrombin time of 60 s, fibrinogen level of 153 mg/dL), acute renal failure, and liver failure. The patient was hemodynamically unstable (blood pressure of 87/53 mm Hg, mean arterial pressure of 64 mm Hg, heart rate of 144 beats/min) and required 5 vasopressors and an inotropic medication: norepinephrine (40 μg/min), vasopressin (0.03 units/min), epinephrine (2 μg/kg/min), phenylephrine (300 μg/min), dopamine (20 μg/kg/min), and dobutamine (10 μg/kg/min). The patient was then started on venoarterial ECMO; a bedside vascular cannulation was accomplished by an ultrasound-guided percutaneous introduction of a wire-reinforced cannula into the left femoral artery (19 French arterial cannula, Bio-Medicus, Medtronic, Minneapolis, Minnesota) and the right femoral vein (25 French multiple-side-port venous cannula, Bio-Medicus, Medtronic). The placement of the venous cannula at the level of the right atrium was confirmed by chest radiograph (Fig. 1). The draining line (venous cannula) was connected to a heparin-coated, hollow-fiber membrane oxygenator (Quadrox-i, Maquet, Wayne, New Jersey), which was powered by a portable heart-lung centrifugal pump (Cardiohelp, Maquet). After ECMO initiation, there was a gradual improvement in hemodynamics, lactic acidosis, and oxygenation. The patient was weaned from norepinephrine, vasopressin, and phenylephrine. Mechanical ventilation settings were reduced to facilitate lung-protective ventilation (breathing frequency of 18 breaths/min, PEEP of 8 cm H2O, peak airway pressure of 28 cm H2O). Chest radiograph showed diffuse alveolar opacities (Fig. 1), and chest computed tomography showed patchy, multifocal lung consolidation with interstitial edema and small bilateral pleural effusions (Fig. 2). An echocardiogram showed global myocardial dysfunction with an estimated left-ventricular ejection fraction of < 20%. On day 2 of ECMO support, an intra-aortic balloon pump was deployed to support cardiac function and prevent left-ventricular distention, and dialysis was initiated to manage volume overload and worsening uremia. Systemic heparinization was monitored and adjusted based on thrombelastography, activated clotting time, and anti-factor Xa activity. The pulse, color, and warmth of the lower extremities, cerebral saturation, and blood gases from the right radial artery were monitored routinely, and there were no signs of lower-limb ischemia or cerebral hypoxia. On day 4, a repeat echocardiogram showed significant improvement in cardiac function (left-ventricular ejection fraction of > 55%); therefore, the intra-aortic balloon pump was removed, and venoarterial ECMO was discontinued. Her oxygenation, hemodynamics, and kidney function improved gradually, and all supportive therapies (inhaled nitric oxide, vasopressors, continuous renal replacement therapy) were discontinued. The patient regained consciousness without neurological deficits. During the following weeks, she participated in physical rehabilitation and was able to ambulate independently. She was weaned from oxygen and discharged home 30 d after admission. Follow-up studies at 6 weeks after hospital discharge showed a small left-sided pleural effusion with normal lung parenchyma (Fig. 3). The patient was seen at 12 and 24 weeks and had normal lung function tests.

Discussion

Compared with O2, CO has greater binding affinity for hemoglobin, myoglobin, and cytochrome, resulting in cellular hypoxia and lactic acidosis. The affinity of CO for hemoglobin is 210 times greater than that of O2.2 The half-life of CO is reduced to 49–99 min with 100% O2 at atmospheric pressure.4 Pulse oximetry and arterial blood gases overestimate and poorly correlate with PaO2 in patients with severe CO poisoning. Pulse oximetry cannot detect carboxyhemoglobin, and measurement of PaO2 from arterial blood gas tends to be normal because PaO2 reflects O2 dissolved in blood (not affected by CO). In contrast, hemoglobin-bound O2 or oxyhemoglobin, which normally composes 98% of PaO2 content, is profoundly reduced in the presence of carboxyhemoglobin. At present, accurate assessment of PaO2 content in CO poisoning can be performed only by analysis of arterial blood by CO-oximetry.5 Although noninvasive carboxyhemoglobin detection is possible today with multi-wavelength pulse-technology, accuracy is somewhat limited by hypoxemia.6

In the presence of carboxyhemoglobin, the oxyhemoglobin dissociation curve shifts to the left and further impairs tissue O2 delivery, leading to cellular hypoxia. CO also interferes with peripheral oxygen utilization by binding to extravascular molecules such as myoglobin, cytochromes, and reduced nicotinamide adenine dinucleotide phosphate hydrogen reductase, resulting in impairment of oxidative phosphorylation in mitochondria. These mechanisms lead to cellular acidosis and may result in cardiovascular collapse, noncardiogenic pulmonary edema, and multiple-organ failure.2

Myocardial ischemia or stunning was previously described in a patient with CO poisoning and heart failure with normal coronary arteries. Myocardial damage is caused by impairment of oxygen utilization rather than by absence of oxygen supply. CO prevents mitochondrial O2 utilization by oxidative phosphorylation in myocardial myoglobin, resulting in cardiac ischemia or stunning and leading to heart failure and pulmonary edema. Myocardial stunning is a reversible process, although the half-life of CO that binds to myoglobin is unknown but is thought to be longer than that of carboxyhemoglobin.3,7 The presence of severe myocardial ischemia in patients with CO poisoning should prompt clinicians to consider the need for left-heart catheterization to rule out concomitant coronary artery disease.

Supplemental 100% oxygen remains the cornerstone of therapy for CO poisoning. Hyperbaric oxygen therapy has been traditionally used in patients with evidence of neurological or myocardial injury from CO poisoning. Hyperbaric therapy increases dissolved O2 content in blood and accelerates elimination of CO.8 Similarly, ECMO results in delivery of super-oxygenated blood (frequently PaO2 of 300–500 mm Hg) to the native circulation, effectively reducing carboxyhemoglobin levels.9 The unstable clinical status of our patient did not allow her to receive hyperbaric oxygen therapy. It is worth mentioning that many patients with severe CO poisoning develop delayed encephalopathy and cognitive sequelae even after 4 weeks of conventional hyperbaric oxygen therapy.10 Our patient was followed for ∼6 months and never reported clinical symptoms of encephalopathy.

To our knowledge, the use of venoarterial ECMO for management of CO poisoning has not been reported previously. We performed a review of the literature using the PubMed and Embase databases, restricting our search to the words ECMO and carbon monoxide, and found only one report of ECMO use in a patient with severe CO poisoning who was supported with venovenous ECMO for 7 d and made a full recovery.11 ECMO use has also been reported in patients with respiratory failure secondary to inhalational injuries. For example, Kornberger et al12 reported a patient with respiratory failure secondary to smoke inhalation injury who was treated by removal of extracorporeal CO2. Similarly, Patton et al13 described a patient with ARDS secondary to thermal burn and inhalational injury who was supported with venovenous ECMO.

For our patient, venoarterial ECMO was chosen over venovenous ECMO due to the presence of cardiogenic shock. Venoarterial ECMO reduced cardiac oxygen consumption and provided both hemodynamic and respiratory support14 as a bridge to recovery in this critically ill patient. Peripheral venoarterial ECMO with femoral and subclavian (or axillary) artery access can be achieved either percutaneously or via an open-surgery approach. Femoral-femoral venoarterial ECMO results in distal retrograde flow and carries the risk of cerebral and coronary hypoperfusion due to competition with anterograde cardiac output ejected from the left ventricle. The mixing point between deoxygenated blood from the left ventricle and oxygenated blood from the ECMO circuit is frequently located at the base of the aortic root, but varies in location depending on the native ejection fraction and ECMO flow.14 Poor lung function with good myocardial function may result in upper-body hypoxemia. In comparison, axillary artery cannulation results in antegrade aortic flow and is preferred for patients with preserved left-ventricular function.15 Compared with femoral percutaneous cannulation, the axillary approach usually requires surgical dissection and is more time-consuming. In our patient, femoral artery access was chosen due to severe hemodynamic instability and need for rapid deployment of ECMO.14 We monitored arterial blood gases from the right radial artery and cutaneous cerebral pulse oximetry to detect upper-body hypoxemia. Concomitant use of an intra-aortic balloon pump improved coronary perfusion with balloon inflation during diastole.14 Another downside of femoral access is ipsilateral lower-extremity ischemia in an arterial-cannulated leg or venous obstruction in a venous-cannulated leg, which can be detected by serial monitoring of lower-extremity pulses and watching for signs of leg ischemia or edema such as swelling, color, and warmth.14 Our patient did not have a problem with venous obstruction or lower-limb ischemia and did not require insertion of a distal perfusion catheter.

Our case adds to the limited available literature showing that venoarterial ECMO can also support patients with severe CO poisoning and should be considered for those with severe hemodynamic compromise. In conclusion, ECMO can be safely and effectively used to support patients with refractory hypoxemia associated with severe CO poisoning. Treatment with ECMO should be considered for patients with CO poisoning who deteriorate despite mechanical ventilation support, particularly when hyperbaric oxygen therapy is not available. Venovenous ECMO has been used in patients with CO poisoning and respiratory failure, but venoarterial ECMO is preferred in patients with cardiogenic shock and hemodynamic instability.
