Predictive factors and clinical impact of ICU-acquired weakness on functional disability in mechanically ventilated patients with COVID-19

Background Patients with critical COVID-19 often require invasive mechanical ventilation (IMV) and admission to the intensive care unit (ICU), resulting in a higher incidence of ICU-acquired weakness (ICU-AW) and functional decline. Objective This study aimed to examine the causes of ICU-AW and functional outcomes in critically ill patients with COVID-19 who required IMV. Methods This prospective, single-center, observational study included COVID-19 patients who required IMV for ≥48 hours in the ICU between July 2020 and July 2021. ICU-AW was defined as a Medical Research Council sum score <48 points. The primary outcome was functional independence during hospitalization, defined as an ICU mobility score ≥9 points. Results A total of 157 patients (age: 68 [59-73] years, men: 72.6%) were divided into two groups (ICU-AW group;n=80 versus non-ICU-AW;n=77). Older age (adjusted odds ratio [95% confidence interval]: 1.05 [1.01–1.11], p = 0.036), administration of neuromuscular blocking agents (7.79 [2.87–23.3], p <0.001), pulse steroid therapy (3.78 [1.49–10.1], p = 0.006), and sepsis (7.79 [2.87–24.0], p <0.001) were significantly associated with ICU-AW development. In addition, patients with ICU-AW had significantly longer time to functional independence than those without ICU-AW (41 [30-54] vs 19 [17-23] days, p<0.001). The development of ICU-AW was associated with delayed time to functional independence (adjusted hazard ratio: 6.08;95% CI: 3.05–12.1;p <0.001). Conclusions Approximately half of the patients with COVID-19 requiring IMV developed ICU-AW, which was associated with delayed functional independence during hospitalization.

Predictive factors and clinical impact of ICU-acquired weakness on functional disability in mechanically ventilated patients with COVID-19.

BACKGROUND: Patients with critical COVID-19 often require invasive mechanical ventilation (IMV) and admission to the intensive care unit (ICU), resulting in a higher incidence of ICU-acquired weakness (ICU-AW) and functional decline. OBJECTIVE: This study aimed to examine the causes of ICU-AW and functional outcomes in critically ill patients with COVID-19 who required IMV. METHODS: This prospective, single-center, observational study included COVID-19 patients who required IMV for ≥48 h in the ICU between July 2020 and July 2021. ICU-AW was defined as a Medical Research Council sum score <48 points. The primary outcome was functional independence during hospitalization, defined as an ICU mobility score ≥9 points. RESULTS: A total of 157 patients (age: 68 [59-73] years, men: 72.6%) were divided into two groups (ICU-AW group; n = 80 versus non-ICU-AW; n = 77). Older age (adjusted odds ratio [95% confidence interval]: 1.05 [1.01-1.11], p = 0.036), administration of neuromuscular blocking agents (7.79 [2.87-23.3], p < 0.001), pulse steroid therapy (3.78 [1.49-10.1], p = 0.006), and sepsis (7.79 [2.87-24.0], p < 0.001) were significantly associated with ICU-AW development. In addition, patients with ICU-AW had significantly longer time to functional independence than those without ICU-AW (41 [30-54] vs 19 [17-23] days, p < 0.001). The development of ICU-AW was associated with delayed time to functional independence (adjusted hazard ratio: 6.08; 95% CI: 3.05-12.1; p < 0.001). CONCLUSIONS: Approximately half of the patients with COVID-19 requiring IMV developed ICU-AW, which was associated with delayed functional independence during hospitalization.

Post COVID-19 Bilateral Facial Nerve Palsy.

Coronavirus disease 2019 (COVID-19) patients have been increasingly reported to develop various neurological manifestations. We herein present a rare case of bilateral facial nerve palsy in a patient that occurred 5 weeks after the onset of COVID-19. The patient had no motor or sensory deficits in his extremities, and there were no other diseases that may have resulted in bilateral facial palsy. Based on these findings, we concluded that the facial palsy in this case may have been triggered by COVID-19.

Neurological Manifestations and Long-term Sequelae in Hospitalized Patients with COVID-19.

Objective Various neurological manifestations have been increasingly reported in coronavirus disease 2019 (COVID-19). We determined the neurological features and long-term sequelae in hospitalized COVID-19 patients. Methods We retrospectively studied 95 consecutive hospitalized patients with COVID-19 between March 1 and May 13, 2020. Acute neurological presentations (within two weeks of the symptom onset of COVID-19) were compared between 60 non-severe and 35 severely infected patients who required high-flow oxygen. In the 12 ventilated patients (the most severe group), we evaluated neurological complications during admission, subacute neurological presentations, and neurological sequelae (51 and 137 days from the onset [median], respectively). Results Of the 95 patients (mean age 53 years old; 40% women), 63% had acute neurological presentations, with an increased prevalence in cases of severe infections (83% vs. 52%, p<0.001). Impaired consciousness and limb weakness were more frequent in severe patients than in non-severe ones (0% vs. 49%; p<0.001, and 0% vs. 54%; p<0.001, respectively). In the most severe group (mean age 72 years old; 42% women), 83% of patients had neurological complications [cerebrovascular disease (17%), encephalopathy (82%), and neuropathy (55%)], and 92% had subacute neurological presentations [impaired consciousness (17%), higher brain dysfunction (82%), limb weakness (75%), and tremor (58%)]. Neurological sequelae were found in 83% of cases, including higher brain dysfunction (73%), limb weakness (50%), and tremor (58%). Conclusions Neurological manifestations are common in COVID-19, with the possibility of long-lasting sequelae.

[COVID-19 and the Hospital Neurologist: How should we confront the COVID pandemic?]

Ninety-six patients were admitted to our hospital during the first wave of the 2020 COVID pandemic. Our hospital, a core hospital in Kobe, was in confusion at the beginning of the pandemic. The following three factors were considered important for preventing the collapse of hospitals during the pandemic based on our experiences: avoidance of contact, prompt and accurate communication, and role-sharing among community medical institutions. Of the 96 patients, 36 had severe cases with several neurological problems: 18 had consciousness disorders, 19 had generalized weakness, 7 had polyneuropathy, and 2 had severe limb weakness. There are several unsolved pathological problems, and neurologists should play important roles in the treatment of patients with COVID.
