Effects of tracheal indwelling pipette on blood oxygen saturation and complications in patients with severe pneumonia

Abstract

Objective To investigate the effect of tracheal indwelling pipette on blood oxygen saturation and complications in patients with severe pneumonia. Methods From December 2014 to December 2016, 68 patients with severe pneumonia in Ji'nan Central Hospital were selected and divided into the observation group and the control group according to the random number table method, with 34 cases in each group.The two groups were given conventional phlegm, anti-infection and other symptomatic treatment.The observation group received suction tube through nasal insertion on the need for suction based on the conventional treatment.The control group received mouth or nasal suction according to the patients' condition at any time based on the conventional treatment.The blood oxygen saturation before and after sputum aspiration were compared in the two groups, the incidence of complications were recorded. Results Before sputum suction, the SpO2, RR in the observation group were (89.5±1.4)%, (31.1±1.5)times/min, respectively, which in the control group were (89.7±1.5)% and (31.2±1.4)times/min, respectively, there were no statistically significant differences between the two groups (t=0.568, P=0.572, t=0.284, P=0.777). After sputum suction, SpO2 was significantly increased in the observation group [(98.4±1.3)%], RR was significantly lower than that before suction[(19.8±2.7)times/min], the differences were statistically significant between the two groups(t=27.163, P=0.000; t=21.333, P=0.000). The SpO2 in the observation group[(98.4±1.3)%] was significantly higher than (90.2±2.6)% in the control group (t=16.448, P=0.000). The overall incidence rate of the complications and mortality in the observation group were 26.5% and 11.8%, respectively, which were significantly lower than 67.6% and 52.9% in the control group (χ2=11.57, P=0.000; χ2=13.17, P=0.000). Conclusion Intravascular retention of suction tube can significantly improve the patients' blood oxygen saturation, reduce the risk of serious complications, and has a positive significance to improve the treatment effect.
