Frank Cutitta worries about all of the patients still suffering with COVID-19 and those who have survived but have lasting damage. A significant number of patients are going to have a prolonged recovery from the comatose state that theyre in, said Dr. Joseph Fins, chief of medical ethics at Weill Cornell Medical College. Additionally, adequate pain control is a . JOSEPH GIACINO: We need to really go slow because we are not at a point where we have prognostic indicators that approach the level of certainty that we should stop treatment because there is no chance of meaningful recovery. BEBINGER: The doctors eventually discharged Frank, but he had to spend a month at Spaulding, the rehab hospital. Some COVID patients are taking nearly a week to wake up. Anesthesia-induced delirium has been highly prominent in medical literature over the past decade and is associated with ventilation. Market data provided by Factset.

"We have studied brain rhythms in patients with COVID-19 using EEG, and have found that patients with COVID-19 have abnormal brain rhythms. Although the patients recovered from their prolonged unconscious state, it is likely that long-term cognitive or physical deficits remain present, in line with many reports on long-term outcomes in patients with COVID-19. The General Hospital Corporation. All patients had a flaccid paralysis after awakening that remained present for the recorded days in the ICU or resolved only very slowly. For some very serious surgeries, such as open-heart surgery or brain surgery, the patient is allowed to slowly wake from anesthesia with no reversal agent to bring the muscles out of paralysis.

It wasnt a serious end-of-life discussion, but Cutitta knew her husband would want every possible lifesaving measure deployed. Clinical researchers thought that SARS-CoV-2 would infect the brain and that injury to the brain would be due, in part, to blood clots. The enigmatic links between COVID-19, neurological symptoms and underlying brain dysfunction are complex. If the patient has not yet lost consciousness as a result of oxygen deficiency which leads to limited amount of oxygenated blood in the brain, then they need to be sedated. The General Hospital Corporation. Patients with COVID-19 who require intubation and ventilation have witnessed a number of stressful events in the ICU, such as emergency resuscitation procedures and deaths. A long ICU course in severe COVID-19 is not unusual. She had been on thyroid supplementary medication during her entire ICU stay, and free thyroxine levels were measured within normal range several times.

When might something change? Given all the unknowns, doctors at the hospital have had a hard time advising families of a patient who has remained unresponsive for weeks, post-ventilator. In 5 of the 6 patients, a mixed or hypoactive delirium was diagnosed after recovery of the unconsciousness. The persistent, coma-like state can last for weeks. Sedatives that are commonly used in the ICU are the benzodiazepines midazolam and lorazepam (and to a lesser extent, diazepam), the short-acting intravenous anesthetic agent propofol, and. However, the impact of COVID-19 treatment on the brain and related cognitive dysfunction (such as problems with memory and attention) is an area of concern for physicians. Patients have many emboli affecting their liver and kidneys, altering the metabolism of sedatives, which can affect the duration of sedation.". SARS-CoV-2 infection can lead to respiratory failure, which is often managed by intubation and mechanical ventilation, and subsequent prolonged sedation is necessary.

On April 21, after 27 days on a ventilator, Franks lungs had recovered enough to remove the breathing tube. Coronavirusinfection starts with inhalation of the virus and its eventual spread to the lungs. Even before the coronavirus pandemic, some neurologists questioned that model. endstream endobj 67 0 obj <. As our case series shows, it is conceivable that neurologists could be faced with the dilemma to prognosticate on the basis of a prolonged state of unconsciousness, all with the background of a pandemic with the need for ICU capacity exceeding available resources.
