The role of tracheotomy in patients with moderate to severe impairment of the lower airways Il ruolo della tracheotomia nei pazienti affetti da disfunzione moderata o severa delle vie aeree inferiori

SUMMARY Patients affected by severe acute respiratory distress syndrome due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have a high likelihood of needing prolonged intubation. As observed worldwide during the Coronavirus Disease 2019 (COVID-19) pandemic, the need for tracheotomy in patients with prolonged respiratory failure has dramatically increased. Tracheotomy in these patients offers several advantages over prolonged translaryngeal intubation: improved patient comfort may allow a reduction in intravenous administration of analgesics, sedatives and muscle relaxant drugs, enhance mobility with particular regard to respiratory muscles, and patients may achieve autonomy earlier. However, there is still debate about the optimal timing and surgical technique of tracheotomy. Similarly, debate is still open regarding the relative merits of open surgical tracheotomy (ST) versus percutaneous dilatational techniques (PDT). In general, PDT is commonly used in elective tracheotomy in adult patients in intensive care units;ST may be preferred depending upon the practitioner’s experience and patient’s characteristics. Correct timing of tracheotomy should be individualised and the indication for tracheotomy should balance the problems related to prolonged intubation and the risk of early or late complications related to the surgical procedure.

Reduction in healthcare services during the COVID-19 pandemic: Patient screening based on symptoms is an effective strategy for avoiding delayed laryngeal cancer diagnosis.

OBJECTIVE: Restriction in healthcare services during the COVID-19 pandemic caused delays in the diagnosis and treatment of several diseases. To overcome the risk of missed diagnosis of head and neck cancers, before deleting the scheduled appointments, we have introduced a selection of the patients by examining the clinical presenting issue and previous medical history. The aim of this study is to show the effects of the abovementioned strategy on the diagnosis and management of laryngeal cancer. METHODS: Data were extracted from the Hospital software regarding the new diagnosis of laryngeal SCC in the periods from March 2020 to December 2020 during the pandemic (study group) and from March 2019 to December 2019 (control group) were collected. Data were compared regarding: TNM stage, time from first medical examination to histological diagnosis (Time-1), and time form histological diagnosis to beginning of treatments (Time-2). RESULTS: The final study group was composed by 19 laryngeal cancers, the control group by 25 cases. No significant differences were found in the tumour stage between the groups. In the study group, Time-1 was shorter (24 days versus 43 days, p = 0.012), while Time-2 in surgically-treated patients was longer (20 days versus 9 days, p = 0.012). CONCLUSION: During the pandemic, there was a dramatic lack of medical and nurse staff needed for surgical procedures. As consequence, the time between the diagnosis of malignancy and surgical treatment increased. In our unit, an efficient patient selection strategy to reschedule medical appointments avoided a dangerous shift toward higher laryngeal cancer stages.

Sinonasal NUT Carcinoma: Delayed Diagnosis Due to the COVID-19 Pandemic and a Review of the Literature.

NUT carcinoma (NUT-C) is a relatively new malignancy that was recently listed in the 4th edition of the WHO Classification of Head and Neck Tumors in 2017. NUT carcinoma is a rare, aggressive, poorly differentiated carcinoma genetically defined by chromosomal rearrangement of the nuclear protein in testis (NUTM1) gene. The prognosis is extremely poor, with a mean survival < 1 year. Recent publications suggest a multimodality treatment approach. In the existing literature, only a few reports of sinonasal NUT-C have been reported. Sinonasal NUT-C is considered a very rare entity, but because of its recent inclusion as a head and neck malignancy, its true prevalence is unknown. We report the case of a 56-year-old woman with NUT-C of the sinonasal cavities. In the case reported, the coexistence of Coronavirus disease 2019 (COVID-19)-related nasal congestion delayed the diagnosis of NUT-C. Clinical presentation, diagnosis and treatment modalities are discussed together with a review of the literature.

Comparison of percutaneous dilatational tracheotomy versus open surgical technique in severe COVID-19: Complication rates, relative risks and benefits.

OBJECTIVE: Patients with acute respiratory failure due to COVID-19 have a high likelihood of needing prolonged intubation and may subsequently require tracheotomy. Usually, the choice of technique (percutaneous dilatational tracheotomy [PDT] versus open surgical tracheotomy [OST]) depends on the preference of surgeons and patient-related factors. In case of COVID-19, airborne spread of viral particles and limited time of apnea must be considered in the choice of the safest technique. The aim of this study is to compare the complication rates and offer an assessment of relative risks and benefits of PDT versus OST in patients with severe COVID-19. METHODS: We performed a retrospective study considering 47 consecutive patients affected by severe acute respiratory distress syndrome due to SARS-CoV-2 infection, needing invasive mechanical ventilation and subsequent tracheostomy. This study was performed at the Intensive Care Unit of our tertiary referral center. Complication rates were analyzed. RESULTS: Seventeen patients underwent PDT and 30 patients were submitted to OST. Twenty-six patients (55.3%) had post-operative complications (local infection, hemorrhage, subcutaneous emphysema) with no significant difference between PDT and OST. CONCLUSION: PDT and OST are characterized by similar postoperative complication rates in severe COVID-19 patients. These findings suggest that OST might be preferred if expert ENT surgeons are available, as PDT could result in longer apnea and exposure to generated aerosol. However, authors recommend considering either OST or PDT at the discretion of the medical staff involved, according to the personal experience of the operators performing the procedure.

The Role of Tracheotomy and Timing of Weaning and Decannulation in Patients Affected by Severe COVID-19.

OBJECTIVES: Patients with acute respiratory failure due to coronavirus disease 2019 (COVID-19) have a high likelihood of needing prolonged intubation and may subsequently require tracheotomy. Indications and timing for performing tracheotomy in patients affected by severe COVID-19 pneumonia are still elusive. The aim of this study is to analyze the role of tracheotomy in the context of this pandemic. Moreover, we report the timing of the procedure and the time needed to complete weaning and decannulation in our center. METHODS: This retrospective, observational cohort study included adults (≥18 years) with severe COVID-19 pneumonia who were admitted to the intensive care unit (ICU) of the tertiary care center of Reggio Emilia (Italy). All patients underwent orotracheal intubation with invasive mechanical ventilation, followed by percutaneous or open surgical tracheotomy. Indications, timing of the procedure, and time needed to complete weaning and decannulation were reported. RESULTS: Forty-four patients were included in the analysis. Median time from orotracheal intubation to surgery was 7 (range 2-17) days. Fifteen (34.1%) patients died during the follow-up period (median 22 days, range 8-68) after the intubation. Weaning from the ventilator was first attempted on median 25th day (range 13-43) from orotracheal intubation. A median of 35 (range 18-79) days was required to complete weaning. Median duration of ICU stay was 22 (range 10-67) days. Mean decannulation time was 36 (range 10-77) days from surgery. CONCLUSIONS: Since it is not possible to establish an optimal timing for performing tracheotomy, decision-making should be made on case-by-case basis. It should be adapted to the context of the pandemic, taking into account the availability of intensive care resources, potential risks for health care workers, and benefits for the individual patient.

Safe tracheotomy for patients with COVID-19

Patients affected by severe acute respiratory syndrome coronavirus 2 disease (COVID-19) with respiratory distress may need invasive mechanical ventilation for a long period of time. Head and neck surgeons are becoming increasingly involved in the care of COVID-19 patients because of the rapidly increasing number of tracheotomies required. This procedure, when performed without protection, may lead to the infection of the medical and nursing staff caring for the patient. The aim of this report is to share our protocol for performing a safe surgical tracheotomy in COVID-19 patients. Infection of the nursing/medical staff involved in the first 30 tracheotomies performed in patients affected by COVID-19 in the Intensive Care Unit of a tertiary referral center were evaluated. Mistakes that occurred during surgery were analyzed and discussed. None of the nursing/medical staff presented signs or symptoms of COVID-19 within 15 days after the procedure. Conclusion: The authors have prepared a protocol for performing a safe surgical tracheotomy in patients affected by COVID-19. Surgeons who might be involved in performing the tracheotomies should become familiar with these guidelines.
