Brief summary

The aim of this prospective, interventional study is to assess the feasibility and safety of the Esophageal Cooling Device in patients from suffering from traumatic brain injury who the treating physician is treating with targeted temperature management. Comparison of outcomes will be made to historical controls. The primary outcome is the feasibility of inducing, maintaining, and rewarming patients from targeted temperature management using the Esophageal Cooling Device (cooling rate, rewarming rate, and the percent of time within goal temperature during the goal-temperature maintenance period). Evaluation of adverse events (including cardiac arrhythmias, severe bradycardia, myocardial infarction/re-infarction, dysphagia, odynophagia, aspiration pneumonia, non-aspiration pneumonia, reflux, esophageal injury, and esophagitis) will be closely monitored during the whole period of targeted temperature management (secondary endpoint).

Detailed description

Controlling patient's body temperature, and in particular, reducing body temperature in a treatment referred to as targeted temperature management, has been shown to improve outcomes for many conditions, including neonatal hypoxic ischemic encephalopathy, cardiac arrest, and traumatic brain injury. However, available modalities for inducing targeted temperature management have a number of technical, logistical, and financial barriers. The Esophageal Cooling Device is a multi-chambered silicone tube placed in the esophagus that provides a highly efficient heat transfer to or from a patient. Traumatic brain injury (TBI) is a major cause of death and severe disability throughout the world. Current methods of traumatic brain injury treatment include reduction of brain swelling and edema, both by surgical means, as well as by reduction of temperature and avoidance of fever. Methods used to reduce temperature and control fever include surface devices, such as ice packs and water circulating blankets, and intravascular catheters, which are placed into a blood vessel. The esophagus is in close proximity to blood flow from the heart and great vessels, and the Esophageal Cooling Device (ECD) is designed to take advantage of this heat exchange environment. The ECD's ability to decompress the stomach and avoid distention of the esophagus away from the device ensures good contact with the esophageal mucosa, and thus maximizes heat transfer from the patient. The ECD replaces the standard gastric tube which is placed in the target patient population as a routine standard of care, is made of standard medical-grade silicone, and is generally similar in size and shape to the gastric tubes currently used. Initial mathematical, animal, and human data have shown strong support for the efficacy and safety of the ECD. The aim of this prospective, interventional study is to assess the feasibility and safety of the Esophageal Cooling Device in patients from suffering from traumatic brain injury who the treating physician is treating with targeted temperature management. Comparison of outcomes will be made to historical controls. The primary outcome is the feasibility of inducing, maintaining, and rewarming patients from targeted temperature management using the Esophageal Cooling Device (cooling rate, rewarming rate, and the percent of time within goal temperature during the goal-temperature maintenance period). Evaluation of adverse events (including cardiac arrhythmias, severe bradycardia, myocardial infarction/re-infarction, dysphagia, odynophagia, aspiration pneumonia, non-aspiration pneumonia, reflux, esophageal injury, and esophagitis) will be closely monitored during the whole period of targeted temperature management (secondary endpoint).

Inclusion criteria

* Patient population will consist of 15 patients suffering from traumatic brain injury, in whom the treating clinician has determined that targeted temperature management will be initiated.

Exclusion criteria

* Patients with known esophageal deformity or evidence of esophageal trauma (for example, known esophageal varices, cirrhosis, history of esophagectomy, previous swallowing disorders, achalasia, etc.). * Patients with known ingestion of acidic or caustic poisons within the prior 24 hours. * Patients with less than 40 kg of body mass. * Patients known to be pregnant. * Terminal disease or do not resuscitate order that could lead to early-onset therapeutic withdrawal. * Unstable hemodynamic conditions that could lead to multi-organ failure and early-onset death. * Pre-existing severe conductive disorder requiring pacing.
