The effect of the endotracheal tube cuff shape on post-operative sore throat in surgeries longer than 120 min in supine position.

BACKGROUND: This study aimed at comparing the effects of cylindrical- and conical-cuff endotracheal tubes (ETTs) inflated with saline on cuff pressures, post-operative sore throat, and post-operative analgesic consumption in surgeries taking longer than 120 min. OBJECTIVE: This study aimed at comparing the effects of cylindrical- and conical-cuff endotracheal tubes (ETTs) inflated with saline on cuff pressures, post-operative sore throat, and post-operative analgesic consumption in surgeries taking longer than 120 min. METHODS: The study was performed on a total of 100 patients, aged 18-65 years, in the ASA I-III risk group, with cylindrical cuff (Group C, n = 50) and conical cuff (Group T, n = 50) ETT patients. Cuff pressure values of all patients were recorded. RESULTS: The cuff pressure values at all measurement times and maximum cuff pressure value were significantly lower in Group T than in Group C (p < 0.05). In the post-operative 24-h period, sore throat and total analgesic consumption were significantly lower in Group T than in Group C (p < 0.05). CONCLUSION: conical cuff ETTs prevent the increase in intraoperative cuff pressures, reduce the incidence of post-operative sore throat, and accordingly reduce post-operative analgesic consumption compared to cylindrical cuff ETTs.

ANTECEDENTES: El objetivo de este estudio fue comparar los efectos de los tubos endotraqueales (ETT) de manguito cilíndrico y cónico inflados con solución salina sobre las presiones del manguito, el dolor de garganta postoperatorio y el consumo de analgésicos postoperatorios en cirugías de más de 120 min de duración. OBJETIVO: Comparar los efectos de los tubos endotraqueales de manguito cilíndrico y cónico inflados con solución salina sobre las presiones del manguito, el dolor de garganta posoperatorio y el consumo de analgésicos posoperatorios en cirugías de más de 120 minutos de duración. MÉTODO: El estudio se realizó en 100 pacientes con edades entre 18 y 65 años, con riesgo ASA I-III, con tubo endotraqueal de manguito cilíndrico (grupo C, n = 50) o manguito cónico (grupo T, n = 50). RESULTADOS: Los valores de presión del manguito en todos los tiempos de medición y el valor máximo de presión del manguito fueron significativamente más bajos en el grupo T que en el grupo C (p < 0.05). En el período de 24 horas del posoperatorio, el dolor de garganta y el consumo total de analgésicos fueron significativamente menores en el grupo T que en el grupo C (p < 0.05). CONCLUSIONES: Los tubos endotraqueales de manguito cónico previenen el aumento de las presiones intraoperatorias del manguito, reducen la incidencia de dolor de garganta posoperatorio y, en consecuencia, disminuyen el consumo de analgésicos posoperatorios en comparación con los de manguito cilíndrico.

Timeline of critically ill 2019 SARS-CoV-2 cases after onset of illness: Intensive care data from Turkey.

Introduction: This study aimed to evaluate the epidemiological, clinical, laboratory characteristics and treatment and clinical outcomes of severe COVID19 cases from a 3rd degree intensive care unit in Turkey. Materials and Methods: The study was conducted in a level three, 16-bed COVID intensive care unit. The investigation was planned as a retrospective and observational study. Patients who were admitted with COVID-19 pneumonia and respiratory failure in the intensive care unit between March 2020 and March 2021 and followed up due to critical illness were evaluated. Result: A total of 213 patients that were admitted to the intensive care unit with the diagnosis of COVID-19 pneumonia were included in the study. Median age of the patients was 66 (IQR 56.5-74) years, and 134 (62.9%) were males. One hundred and sixty-six (77.9%) of the patients had at least one comorbidity. Patients were followed up mainly with invasive mechanical ventilation [104 (48.8%)] and high flow nasal cannula [67 (31.5%)]. Median number of days was 7 (IQR 4-10) and included the first symptom onset to intensive care admission. The time to intubation was 9 (IQR 4-15) days, and the median day to intensive care discharge was 16 (IQR 11-23). After the symptoms started, first tocilizumab 9 (IQR 5-11) and pulse steroid treatment 8 (IQR 3-11) were found to be close to each other. In total, 95 (44.6%) of the 213 patients died. Conclusions: SARS-CoV-2 associated viral disease can progress after simple symptoms to hospital admission in a median of four days and to intensive care admission requiring intubation in a median of nine days. We believe that a better understanding of the clinical course of COVID-19 and its change between centers can be revealed through sharing information from different countries and centers.
