Objective To investigate the application value of oxygenation atomization combined
with high-frequency vibration sputum extraction in airway management after
tracheotomy and its effect on lung function.
Methods The clinical data of 69 patients who underwent tracheotomy for various
reasons in Guangzhou Xinhai Hospital and Guangdong First Invalides Hospital
from August 2020 to August 2021 were retrospectively analyzed, including 41
males and 28 females, and they were 31-81 years old. They were randomly divided
into an oxygen atomization combined with high frequency vibration expectoration
drainage group (38 cases; experimental group) and a conventional sputum suction
group (31 cases, control group). According to airway stranded sputum volume,
timely sputum suction was carried out. The nature sputum in within 1 week,
callus, the amounts of expectoration drainage, lung infection symptoms, sputum
culture, blood oxygen activities, and lung function indicators in both groups
were observed and compared. The count data were expressed as cases (%), and
compared between the two groups by
χ2 test. The measurement data were expressed as (
x±s
), and were compared between these two groups by independent-sample
t test.
Results The 38 patients in the observation group had taken oxygenation
atomization combined with high frequency vibration expectoration 462 times
within one week, and 7 cases did sputum culture; the 31 patients in the control
group had underwent sputum suction 1 316 times, and 13 cases did sputum
culture. The sputum scab rate, sputum purulence rate, expectoration frequency,
sputum volume per time, incidence of lung infection, and positive rate of
sputum culture were 27.7% (128/462), 21.8% (101/462), (11.0±3.4), (26.0±5.5)
ml, 18.4% (7/38), and 42.9% (3/7) in the experimental group, and were 47.6%
(627/1 316), 44.7% (589/1 316), (33.0±6.8), (15.0±3.5) ml, 41.9% (13/31), and
76.9% (10/13) in the control group, with statistical differences (
P=0.021, 0.016, 0.015, 0.031, 0.017, and
0.036). The rate of conscious patients completing lung function exercise was
86.8% (33/38) in the experimental group, and was 38.7% (12/31) in the control
group, with a statistical difference (
P=0.038).
The sputum volume records showed that the proportion of total sputum volume
within 3 days to the total sputum volume in 1 week was 67.8% (8 200/12 100) in
the experimental group, and was 51.8% (10 200/19 700) in the control group,
with a statistical differences (
P=0.452).
One week later, the heart rate, respiration, arterial oxygen saturation,
partial pressure of oxygen, and lung function in the experimental group were
better than those in the control group, but there no statistical differences
(all
P> 0.05). No one stopped the
treatment because of obvious palpitation, shortness of breath, and blood
pressure fluctuation.
Conclusions Oxygenation
atomization combined with high-frequency vibration expectoration can
effectively dilute sputum, prevent sputum scab, and promote sputum excretion.
Compared with conventional expectoration, it can significantly reduce the
frequency of expectoration and the incidence of lung infection and maximize the
coordination with pulmonary function rehabilitation.
