RESUMO
BACKGROUND: Takotsubo cardiomyopathy (TC) is a well-known complication of subarachnoid haemorrhage (SAH), often accompanied by neurogenic myocardial dysfunction. Although TC has been reported to be associated with higher morbidity and mortality among patients with aneurysmal SAH (aSAH), some patients have been reported to recover, the profiles and follow-up outcomes of these survivors remain unclear. MATERIALS AND METHODS: To characterize the profiles of patients with aSAH complicated by TC who experienced favourable outcomes using long-term follow-up data, a consecutive series of patients with aSAH were enrolled and TC diagnosis was based on the revised version of the Mayo Clinic criteria. Clinical outcomes were assessed at 6 months according to modified Rankin Scale scores. RESULTS: Among 165 consecutive patients with aSAH, 15 cases were complicated by TC, corresponding to an occurrence rate of 9.0%. Five patients with aSAH complicated by TC (33.3%) experienced a favourable outcome, and the mean value of systolic blood pressure on arrival was significantly lower than in those who experienced an unfavourable outcome (p = 0.032). CONCLUSION: According to analysis, it is possible cardiac dysfunction with decreased cerebral perfusion pressure and catecholamine toxicity transiently worsens conscious disturbance in aSAH complicated by TC. Therefore, it is important to carefully screen patients with aSAH to identify those complicated by TC, and for close collaboration of the multidisciplinary team to design appropriate treatment strategies.
RESUMO
BACKGROUND: Computed tomography (CT) is often performed to assess patients; however, little is known about how airway size measured by CT scan imaging might influence the occurrence of post-extubation upper airway obstruction. METHODS: This study aimed to evaluate the association between airway size measured by CT and the incidence of post-extubation upper airway obstruction symptoms for each sex. This single-center observational study was conducted at a tertiary emergency medical center/severe trauma center with a 12-bed intensive care unit. We enrolled consecutive adult patients (aged ≥ 20 years), who were intubated in the emergency room, between January 2016 and March 2019. Patients who underwent a CT scan of the glottic region within three hours before and after intubation were included in the analysis. For each sex, we first divided the patients into two groups: those who had post-extubation stridor, hoarseness, or both and those who had no such symptoms. Then, we compared the two groups using the Mann-Whitney U test and Fisher's exact test. Univariate and multivariate logistic regression analyses were also performed. RESULTS: During the 39 months, 855 patients were enrolled in this study. A total of 217 patients underwent CT of the glottic region within three hours before and after intubation. Five patients had no records of symptoms after extubation. Thus, we analyzed data from 212 patients. This study included 144 males and 68 females. In female patients, the median [inter-quartile range] (average) of the transverse diameter of the glottis/endotracheal tube outer diameter (OD) ratio was smaller in patients with post-extubation upper airway obstruction symptoms than in patients without the symptoms (1.00 [1.00-1.00] (0.9572) vs. 1.00 [1.00-1.00] (1.00296), respectively; p = .013). Multivariate logistic regression analysis showed that the glottis/tube OD ratio < 1 was associated with the symptoms in females (odds ratio: 95% confidence interval, 5.68: 1.04-30.97). There was no relation between the airway sizes and the symptoms in male patients. CONCLUSIONS: In female patients, no gap between the endotracheal tube and the vocal codes or the glottic transverse diameter being smaller than the endotracheal tube OD on CT scan was associated with post-extubation upper airway obstruction symptoms.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pneumonitis associated with severe respiratory failure is associated with high mortality. The pathogenesis of COVID-19 is associated with microembolism or microvascular endothelial injuries. Here, we report that syndecan-1 (SDC-1), a component of the endothelial glycocalyx, may be a biomarker of severity classification for COVID-19 related to endothelial injury. METHODS AND ANALYSIS: We analyzed the data of COVID-19 patients for 1 year from February 2020 at Yokohama City University Hospital and Yokohama City University Medical Center Hospital. We selected COVID-19 patients who required admission care, including intensive care, and analyzed the classification of severe and critical COVID-19 retrospectively, using various clinical data and laboratory data with SDC-1 by ELISA. RESULTS: We analyzed clinical and laboratory data with SDC-1 in five severe COVID-19 and ten critical COVID-19 patients. In the two groups, their backgrounds were almost the same. In laboratory data, the LDH, CHE, and CRP levels showed significant differences in each group (P = 0.032, P < 0.0001, and P = 0.007, respectively) with no significant differences in coagulation-related factors (platelet, PT-INR, d-dimer, ISTH score; P = 0.200, 0.277, 0.655, and 0.36, respectively). For the clinical data, the SOFA score was significantly different from admission day to day 14 of admission (p < 0.0001). The SDC-1 levels of critical COVID-19 patients were significantly higher on admission day and all-time course compared with the levels of severe COVID-19 patients (P = 0.009 and P < 0.0001, respectively). CONCLUSIONS: Temporal change of SDC-1 levels closely reflect the severity of COVID-19, therefore, SDC-1 may be a therapeutic target and a biomarker for the severity classification of Covid-19.
RESUMO
Fatigue reduces productivity and is a risk factor for lifestyle diseases and mental disorders. Everyone experiences physiological fatigue and recovers with rest. Pathological fatigue, however, greatly reduces quality of life and requires therapeutic interventions. It is therefore necessary to distinguish between the two but there has been no biomarker for this. We report on the measurement of salivary human herpesvirus (HHV-) 6 and HHV-7 as biomarkers for quantifying physiological fatigue. They increased with military training and work and rapidly decreased with rest. Our results suggested that macrophage activation and differentiation were necessary for virus reactivation. However, HHV-6 and HHV-7 did not increase in obstructive sleep apnea syndrome (OSAS), chronic fatigue syndrome (CFS) and major depressive disorder (MDD), which are thought to cause pathological fatigue. Thus, HHV-6 and HHV-7 would be useful biomarkers for distinguishing between physiological and pathological fatigue. Our findings suggest a fundamentally new approach to evaluating fatigue and preventing fatigue-related diseases.

BACKGROUND: Cognitive behavioral therapy for insomnia (CBT-I) is among the recommended non-pharmacological treatments for patients with insomnia. While there are multiple reports on the effects of CBT-I treatment, few studies evaluating the factors associated with the treatment response to CBT-I have been reported. The present study aimed to confirm the effects of CBT-I in patients with insomnia and to examine the clinico-demographic factors that can predict the outcomes of CBT-I in these patients. METHODS: Overall, 62 patients were included in the present study. To confirm the effectiveness of CBT-I, we compared the pre- and post-CBT-I therapy values of several sleep parameters. Furthermore, to identify the clinico-demographic factors that could be predictive of the treatment response to CBT-I, we performed generalized linear model (GLM) analysis. RESULTS: The values of several sleep parameters were significantly lower after treatment than at baseline. The results of the GLM analysis revealed that sex and occupation were significantly associated with the treatment response to CBT-I. CONCLUSIONS: The present results suggest that several clinico-demographic factors should be considered in the treatment of patients with insomnia.
RESUMO
BACKGROUND: Therapeutic hypothermia (TH) is one of the key treatments after cardiac arrest (CA). Selection of post-CA patients for TH remains problematic, as there are no clinically validated tools to determine who might benefit from the therapy. OBJECTIVE: The aim of this study was to investigate retrospectively whether laboratory findings or other patient data obtained during the early phase of hospital admission could be correlated with neurological outcome after TH in comatose survivors of CA. METHODS: Medical charts of witnessed CA patients admitted between June 2003 and July 2009 who were treated with TH were reviewed retrospectively. The subjects were grouped based on their cerebral performance category (CPC) 6 months after CA, as either good recovery (GR) for CPC 1-2 or non-good recovery (non-GR) for CPC 3-5. The following well-known determinants of outcome obtained during the early phase of hospital admission were evaluated: age, gender, body mass index, cardiac origin, presence of ventricular fibrillation (VF), time from collapse to cardiopulmonary resuscitation, time from collapse to return of spontaneous circulation, body temperature, arterial blood gases, and blood test results. RESULTS: We analyzed a total of 50 (25 GR and 25 non-GR) patients. Multivariate logistic analysis showed that initial heart rhythm and pH levels were significantly higher in the GR group than in the non-GR group (ventricular tachycardia/VF rate: p = 0.055, 95% confidence interval [CI] 0.768-84.272, odds ratio [OR] 8.047; pH: 7.155 ± 0.139 vs. 6.895 ± 0.100, respectively, p < 0.001, 95% CI 1.838-25.827; OR 6.89). CONCLUSION: These results imply that in addition to initial heart rhythm, pH level may be a good candidate for neurological outcome predictor even though previous research has found no correlation between initial pH value and neurological outcome.

BACKGROUND: Subarachnoid hemorrhage and thyroid storm are similar in their clinical symptomatology, and diagnosis of these conditions, when they occur simultaneously, is difficult. Here, we report a rare case of concurrent subarachnoid hemorrhage and thyroid storm we encountered at our hospital. CASE PRESENTATION: The patient was a 52-year-old woman. While bathing at home, the patient experienced a sudden disturbance of consciousness and was brought to our hospital. The main physical findings upon admittance were Glasgow Coma Scale score of E1V2M4, elevated blood pressure (208/145 mmHg), and tachycardia with atrial fibrillation (180 bpm) along with body temperature of 36.1 °C. Brain computed tomography revealed subarachnoid hemorrhage associated with a ruptured aneurysm of the posterior communicating artery branching from the left internal carotid artery, and aneurysm clipping was performed. Blood tests upon admission revealed high levels of free T3 and free T4 and low levels of thyroid-stimulating hormone. Upon determining that the patient had hyperthyroidism, thiamazole was administered. However, due to continuous impaired consciousness, fever, and persistence of tachycardia, the patient was diagnosed with thyroid storm. Oral potassium iodide and hydrocortisone were added to the treatment. The treatment was successful as the patient's symptoms improved, and she became lucid. In this case, we believe that in the presence of untreated hyperthyroidism, the onset of subarachnoid hemorrhage induced thyroid storm. Tachycardia of 130 bpm or higher, which is the diagnostic criterion for thyroid storm, rarely occurs with subarachnoid hemorrhage. Therefore, we believe it is an important factor for recognizing the presence of the thyroid storm. In this case, clipping surgery was prioritized which resulted in a favorable outcome. However, it is possible that invasive surgery may have exacerbated thyroid storm, suggesting that treatment should be tailored as per patient's condition. CONCLUSION: If a pulse rate of 130 bpm or higher is observed alongside subarachnoid hemorrhage, we recommend considering the possibility of concomitant thyroid storm and testing for thyroid hormone. If concomitant thyroid storm is present, we believe that a treatment plan tailored to the patient's condition is critical, and early diagnosis will lead to a favorable outcome for the patient.
RESUMO
Background: Continuous positive airway pressure (CPAP) therapy is an effective treatment for patients with severe heart failure, and certain guidelines recommend its early initiation. However, the current Japanese law strictly prohibits paramedics from administering this treatment. To demonstrate the efficacy and safety of prehospital administration of CPAP therapy, this study was conducted by the Yokohama Medical Control Council (Yokohama MC). Methods: The Yokohama MC established a protocol for CPAP treatment and dispatched Doctor Cars to attend to patients with severe respiratory failure. The Boussignac CPAP system was installed in all Yokohama Doctor Cars, including Workstation-type Doctor Cars and Hospital-type Doctor Cars. Data from this study were collected and recorded in the Yokohama City Doctor Car Registry system from October 2020 to January 2022. Results: The Doctor Car was dispatched 661 times, and CPAP therapy was administered to 13 patients in the prehospital field. It is important to note that the number of CPAP cases was lower than anticipated due to the coronavirus disease 2019 (COVID-19) pandemic, given concerns about aerosol production. When assessing changes over time in oxygen saturation (SpO2), the median (interquartile range), excluding missing values, was 89% (83%-93%) without oxygen, 95% (94%-99.3%) with oxygen, and 100% (97%-100%) with CPAP. The differences between these groups were statistically significant with a p-value of <0.0001. Respiratory distress was primarily attributed to heart failure in 10 patients (91%) and pneumothorax in 1 patient (9%). Notably, none of the patients' conditions worsened after the use of CPAP. Conclusion: We have detailed the administration of CPAP therapy in the prehospital field within a local city in Japan. To the best of our knowledge, this represents the inaugural report of a prospective observational study on the prehospital administration of CPAP therapy originating from Japan.
RESUMO
Recently, addiction to regular doses of hypnotics has become a problem. While many patients report a desire to reduce their dosage, many do not agree with their physicians' suggestions for reduction. In this study, we created an online short video targeting patient motivation to reduce hypnotics usage and examined its efficacy and factors associated with the intention to reduce medication. We created a 10 min video that included "sleep education," "guidance for reducing the use of hypnotics," and "systematic motivation for reducing the use of hypnotics" and posted it on our website. For 1 year, we conducted a questionnaire survey to determine the effectiveness of the video and factors associated with the intention to reduce hypnotics use. Of 4548 viewers, 609 (13.4%) completed the questionnaire, 369 (67.9%) of whom used hypnotics. Most respondents were older adults. The intention to reduce medication use was significantly strengthened after watching the video in 37.7% of medication users (effect size 0.404). In the group that was not inclined toward medication reduction before viewing, 85.2% of patients had stronger intentions to reduce medication use after watching the video (effect size 0.818). "Memorable content about side effects" was extracted as a factor related to reinforcement of the intention to reduce medication use, suggesting that prescribing physicians' descriptions of current insomnia treatment is inadequate in explaining side effects to patients. A short informational video can have beneficial effects on patients' motivation for dose reduction or cessation of hypnotics. Supplementary Information: The online version contains supplementary material available at 10.1007/s41105-023-00446-4.
RESUMO
BACKGROUND: High-echoic objects in the hepatic vessels of patients with cardiopulmonary arrest (CPA) are frequently detected by ultrasonography. OBJECTIVE: To demonstrate this phenomenon and clarify its clinical characteristics. METHODS: In a tertiary care academic medical centre, 203 CPA patients were evaluated by ultrasonography. CT determined the origin and location of high-echoic objects detected in the liver. The frequency and characteristics of this phenomenon were investigated. The background, laboratory data and survival rate were compared between patients with and without high-echoic objects. RESULTS: High-echoic objects were seen in 73 (36.0%) patients and could clearly be detected in the hepatic veins of 41 (56.2%) patients. CT confirmed that these were gas in 27 of 53 patients, and were clearly visible in the hepatic veins in 12 (44.4%) patients. Hepatic portal venous gas was not identified. Compared to patients without high-echoic objects, witnessed arrest (p<0.001), bystander cardiopulmonary resuscitation (p=0.005), ventricular fibrillation or pulseless electrical activity (p=0.012) and return of spontaneous circulation (p=0.018) were significantly less frequent in patients with high-echoic objects. These patients had a lower incidence of survival to discharge (1.4% vs 7.7%, p=0.100). Multivariate analysis showed that absence of high-echoic objects was a marginally significant factor in association with return of spontaneous circulation (p=0.052). CONCLUSIONS: High-echoic objects were often observed on ultrasonography in CPA patients; these objects were considered hepatic venous gas. The presence of high-echoic objects may be a poor prognostic sign in patients with CPA.

Forty eight year-old woman with untreated liver cirrhosis was transferred to our critical care and emergency center because of airway crisis due to retropharyngo-esophageal hematoma after slight chest contusion. We performed emergency tracheal intubation beyond stenotic part of the trachea. The hematoma did not diminished in a few days. Although we considered tracheostomy, we hesitated to perform conventional median tracheostomy because of the risk of complication of infection of the hematoma which might require drainage or removal resulting in contamination between tracheostomy site and cervical wound. We performed paramedian tracheostomy by antero-lateral skin incision to avoid these risks. Fortunately, the patient did not require drainage of the retropharyngo-esophageal hematoma. Paramedian tracheostomy should be taken into account for patients with presumably contaminated cervical wound.

The average of sleep time in Japanese is decreasing year by year. According to data of NHK's survey, it has been lowered by one hour since 1960. The reasons are different between generations. In adolescence, the increased frequency of using internet and convenience store may cause the shortage of sleep and the deterioration of circadian rhythms. In adulthood, the working environment, such as increased number of shift-workers and excessive job time, is getting worse, and it could shorten the sleep time and exacerbate sleep quality. In old age, the frequency of taking medicine becomes higher in connection with aging. We need to be careful about the interactions between hypnotics and taking drugs prescribed to treat complications.

In coronavirus disease 2019 (COVID-19), veno-venous extracorporeal membrane oxygenation (VV-ECMO) is used to manage respiratory distress. This study's key clinical question was whether COVID-19 could be complicated by hemorrhagic and thrombotic events, such as iliopsoas hematoma (IPH), during the management of ECMO and the method to quickly and effectively detect IPH. A 52-year-old man with fever and dyspnea was diagnosed with COVID-19 pneumonia. He warranted VV-ECMO management on day 9, which was successfully tapered off on day 18. On day 20, computed tomography revealed a unilateral iliopsoas hematoma that was successfully managed with conservative care. However, a retrospective review of abdominal radiography performed on day 14 revealed a positive left psoas sign. When managing severe COVID-19 patients with VV-ECMO, cautious anticoagulative care and abdominal X-ray findings are warranted when considering the diagnosis of iliopsoas hematoma, including circulatory instability, anemia, and pain associated with limb movement.
RESUMO
Lung ultrasound (LUS), a rapid, bedside, goal-oriented diagnostic test, can be quantitatively assessed, and the scores can be used to evaluate disease progression. However, little data exists on predicting prolonged mechanical ventilation (PMV) and successful extubation using serial LUS scores. We examined the relationship of PMV with successful extubation in patients with severe coronavirus disease (COVID-19) by using two types of serial LUS scores. One LUS score evaluated both the pleura and lung fields, while the other assessed each separately (modified-LUS score). Both LUS scores were determined for 20 consecutive patients with severe COVID-19 at three timepoints: admission (day-1), after 48 h (day-3), and on the seventh follow-up day (day-7). We compared LUS scores with the radiographic assessment of the lung oedema (RALE) scores and laboratory test results, at the three timepoints. The PMV and successful extubation groups showed no significant differences in mortality, but significant differences occurred on day-3 and day-7 both LUS scores, day-7 RALE score, and day-7 PaO2/FiO2 ratio, in the PMV group (p<0.05); and day-3 and day-7 modified-LUS scores, day-7 C-reactive protein levels, and day-7 PaO2/FiO2 ratio, in the successful extubation group (p<0.05). The area under the curves (AUC) of LUS scores on day-3 and day-7, modified-LUS scores on day-3 and day-7,RALE score on day-7, and PaO2/FiO2 ratio on day-7 in the PMV group were 0.98, 0.85, 0.88, 0.98, 0.77, and 0.80, respectively. The AUC of modified-LUS scores on day-3 and day-7, C-reactive protein levels on day-7, and PaO2/FiO2 ratio on day-7 in the successful extubation group were 0.79, 0.90, 0.82, and 0.79, respectively. The modified-LUS score on day 7 was significantly higher than that on day 1 in PMV group (p<0.05). While the LUS score did not exhibit significant differences. The serial modified-LUS score of patients with severe COVID-19 could predict PMV.

Background: Since becoming the city with the first government-designated major trauma center in 2014, Yokohama has been striving to centralize care for extensive trauma patients. Hence, in this study, the Yokohama City Major Trauma Care Advisory Committee tested the efficacy of the centralization of care for trauma patients. Methods: This investigation included all cases of deaths due to road traffic accidents that occurred in the 2-year period following the establishment of the major trauma center. The probability of survival was calculated using data provided by the police and fire departments. Cases that died despite having a probability of survival of 50% or more were included in the survey undertaken by physicians recommended by the Japanese Association for the Surgery of Trauma, who visited the hospitals. Results: Of those surveyed, preventable trauma death accounted for 1 case (1.7%) and potentially preventable trauma death accounted for 7 (11.9%), compared with 5 (9.8%) and 11 (21%) cases, respectively, in the period 2009-2010. Conclusions: Comparing the survey conducted before establishment of the major trauma center, those results support the benefits of centralizing care for severe trauma cases. We aim to continue improving trauma care provided through the center along with the Yokohama Medical Control Council and to overcome challenges that were identified through the peer review.
RESUMO
Cognitive behavioral therapy for insomnia (CBT-I) is effective for not only primary insomnia (PI) but also comorbid insomnia (CI; insomnia associated with psychiatric/physical diseases or other types of sleep disorders). This study aimed to compare the outcomes of CBT-I implemented in the same manner between patients with PI and CI. In total, 41 adult patients who had completed CBT-I were enrolled in this retrospective analysis and divided into a PI group and a CI group. The authors then examined and compared the significance of changes after therapy between the two groups. The magnitude of improvement on the Japanese version of the Insomnia Severity Index (ISI-J) was analyzed as the primary endpoint. In the PI group (n = 24), both the ISI-J score and the dose of hypnotics decreased significantly following CBT-I. On the other hand, in the CI group (n = 17), only the dose of hypnotics decreased significantly; no statistically significant improvement was seen in the ISI-J score. Sleep onset latency and sleep quality rating in recorded sleep diaries were significantly correlated with improved ISI-J scores in the CI group only. CBT-I was shown to be effective for CI, but its efficacy for CI was inferior to that for PI in terms of impact on sleep and mental condition. These results suggest that in addition to the basic components of CBT-I, treatment for CI, especially when accompanied by severe insomnia symptoms, should include approaches targeting the comorbid disease.
RESUMO
BACKGROUND: There are few strategies for treating patients who have suffered cardiopulmonary arrest due to blunt trauma (BT-CPA). The aim of this population-based case series observational study was to clarify the outcome of BT-CPA patients treated with a standardized strategy that included an emergency department thoracotomy (EDT) under an emergency medical service (EMS) system with a rapid transportation system. METHODS: The 477 BT-CPA registry data were augmented by a review of the detailed medical records in our emergency department (ED) and action reports in the prehospital EMS records. RESULTS: Of those, 76% were witnessed and 20% were CPA after leaving the scene. In all, 18% of the patients went to the intensive care unit (ICU), the transcatheter arterial embolization (TAE) room, or the operating room (OR). Only 3% survived to be discharged. Among the 363 witnessed patients-11 of whom had ventricular fibrillation (VF) as the initial rhythm, 134 exhibiting pulseless electrical activity (PEA), and 221 with asystole-13, 1, and 3%, respectively, survived to discharge. The most common initial rhythm just after collapse was not VF but PEA, and asystole increased over the 7 min after collapse. There were no differences in the interval between arrival at the hospital and the return of spontaneous circulation between the patients that survived to discharge and deceased patients in the ED, OR, TAE room, or ICU. The longest interval was 17 min. CONCLUSIONS: In BT-CPA patients, a 20-min resuscitation effort and termination of the effort are thought to be relevant. The initial rhythm is not a prognostic indicator. We believe that the decision on whether to undertake aggressive resuscitation efforts should be made on a case-by-case basis.

Computed tomography (CT) is the most reliable method to evaluate the progression of COVID-19 pneumonitis. However, in a pandemic, transportation of critically ill invasively ventilated patients to radiology facilities is challenging, especially for those on extracorporeal membrane oxygenation (ECMO). Notably, lung ultrasound (LUS) is a favored alternative imaging modality due to its ease of use at the point of care, which reduces the infectious risk of exposure and transmission; repeatability; absence of radiation exposure; and low cost. We demonstrated that serial LUS compares favorably with other imaging modalities in terms of usefulness for evaluating lung aeration and recovery in an ECMO-managed COVID-19 patient.
RESUMO
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic rapidly increases the use of mechanical ventilation (MV). Such cases further require extracorporeal membrane oxygenation (ECMO) and have a high mortality. OBJECTIVE: We aimed to identify prognostic biomarkers pathophysiologically reflecting future deterioration of COVID-19. METHODS: Clinical, laboratory, and outcome data were collected from 102 patients with moderate to severe COVID-19. Interleukin (IL)-6 level and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA copy number in plasma were assessed with ELISA kit and quantitative PCR. RESULTS: Twelve patients died or required ECMO owing to acute respiratory distress syndrome despite the use of MV. Among various variables, a ratio of oxygen saturation to fraction of inspired oxygen (SpO2/FiO2), IL-6, and SARS-CoV-2 RNA on admission before intubation were strongly predictive of fatal outcomes after the MV use. Moreover, among these variables, combining SpO2/FiO2, IL-6, and SARS-CoV-2 RNA showed the highest accuracy (area under the curve: 0.934). In patients with low SpO2/FiO2 (< 261), fatal event-rate after the MV use at the 30-day was significantly higher in patients with high IL-6 (> 49 pg/mL) and SARS-CoV-2 RNAaemia (> 1.5 copies/µL) compared to those with high IL-6 or RNAaemia or without high IL-6 and RNAaemia (88% vs. 22% or 8%, log-rank test P = 0.0097 or P < 0.0001, respectively). CONCLUSIONS: Combining SpO2/FiO2 with high IL-6 and SARS-CoV-2 RNAaemia which reflect hyperinflammation and viral overload allows accurately and before intubation identifying COVID-19 patients at high risk for ECMO use or in-hospital death despite the use of MV.

Tracheostomy is hardly performed in patients with cervical infection close to the site of the tracheostomy. This study aimed to present and clarify the usefulness and safety of open tracheostomy performed by the paramedian approach technique. The procedure is as follows. A 2.5-cm paramedian incision is made for the tracheostomy on the opposite side of infectious focus; the anterior neck muscles are dissected and split; the trachea is fenestrated by a reverse U-shaped incision; and the fenestral flap of the trachea is fixed to the skin. We used this technique in five patients. There were no complications such as bleeding, desaturation, and displacement of the tube; and there were no postoperative complications such as severe contamination or infection of the tracheostomy site from the nearby cervical wound, difficulty in securing the tracheostomy tube and connecting device to the ventilator, difficulties in daily management and care, or dislocation of the tracheostomy tube. All wounds resulting from the tracheostomy were kept separate from and not contaminated by the nearby dirty wounds. Open tracheostomy by the paramedian approach technique is useful and safe for patients with severe cervical infection requiring open drainage and long ventilatory management.
