Application value of T-tube combined with Venturi warm humidifying oxygen therapy in patients with tracheotomy offline

ObjectiveTo investigate the clinical application effects of T-tube combined with Venturi warm humidifying oxygen therapy in patients with tracheotomy offline.

MethodsFifty-eight patients aged ≥ 18 years old treated with tracheotomy offline were investigated, and divided into the observation group (28 cases, from January to December 2019) and control group (30 cases, from January to December 2018) according to the time of admission. The observation group was treated with T-tube combined with Venturi warm humidifying oxygen therapy, and the control group was treated with conventional airway humidification. The respiratory rate, oxygenation index (PaO₂/FiO₂), blood oxygen saturation (SpO₂), arterial partial pressure of carbon dioxide (PaCO₂), viscosity of sputum, times of sputum suction, decline of SpO₂ during sputum suction, duration of SpO₂ decline during sputum aspiration, ICU residence time and incidence rate of complications were compared between two groups at offline and after 1 and 5 days of offline.

ResultsAfter 1 day and 5 days of offline, the respiratory rate in observation group was lower than that in control group (P < 0.01), the value of PaO₂/FiO₂ in observation group was higher than that in control group (P < 0.01), and the sputum viscosity in observation group was better than that in control group (P < 0.05 and P < 0.01). The number of sputum aspiration, decreasing degree of SpO₂ during sputum aspiration, decreasing duration of SpO₂ during sputum aspiration and ICU stay time in observation group were lower than those in control group (P < 0.01). The incidence rates of irritating cough (3.57%), phlegm scab formation (0.00%), pulmonary infection (0.00%) and airway bleeding (7.14%) ine observation group were lower than those in control group (33.33%, 20.00%, 20.00%, and 26.67%) (P < 0.05 to P < 0.01).

ConclusionsThe application of Venturi oxygen therapy in patients with tracheotomy offline can meet the physiological needs of human body temperature humidification, avoid the patient's cough and discomfort, improve sputum viscosity and respiratory parameters and reduce the occurrence of complications, and it is worthy of clinical promotion.
