Results
Patients characteristics are shown in Table 3.
The clinical severity and prognosis are presented in Table 4.
The drowning patient groups with long hospitalization (p=0.003),
intubation (p<0.0001 or antibiotics (p=0.01) had higher severity score of air-space consolidation on CT.
The patient group without intubation had higher severity score of multiple lobular opacities on CT (p=0.01).
Non-survivors (p=0.01) and patients with brain anoxia (p=0.03) or long hospitalization (p=0.01) had higher severity score of consolidation on chest X-ray (Table 5).
Univariate and multivariate logistic analysis for treatment outcomes are shown in Table 6 and Table 7.
Older age (OR:1.1,
CI:1.0-1.1,
p=0.01),
clinical severity (OR:2.5,
CI:1.3-6.1,
p=0.006),
larger amount of air-space consolidation on CT (OR:2.7,
CI:1.4-6.4,
p=0.002),
larger amount of consolidation of chest X-ray (OR:1.9,
CI:1.1-3.4,
p=0.02) are related to long stay in univariate analysis,
however,
there was no significance in multivariate analysis.
Clinical severity (OR:1000<,
CI:0-106<,
p=0.01),
larger amount of air-space consolidation (OR:5.2,
CI:2.3-16,
p<0.0001) and fewer amount of multiple lobular opacities (OR:0.4,
CI:0.1-0.8,
p=0.009) on CT were related to need for intubation in univariate analysis.
Larger amount of air-space consolidation (OR:17.9,
CI:3.6-532,
p<0.0001) and fewer amount of multiple lobular opacities (OR:0.1,
CI:0-0.6,
p=0.006) on CT were related to need for intubation in multivariate analysis adjusted with age and sex.
Male sex (OR:11,
CI:2.0-90,
p=0.004),
larger amounts of air-space consolidation on CT (OR:3.1,
CI:1.4-11,
p=0.005) were related to need for antibiotics in univariate analysis. Larger amount of air-space consolidation on CT (OR:3.1,
CI:1.1-12,
p=0.02) was related to need for antibiotics in univariate analysis adjusted with age and clinical severity.
