Abstract:
Objective:To explore the risk factors influencing the prognosis of elderly patients with acute poisoning.
Methods:We retrospected 177 elderly patients with Acute Poisoning who were treated in the emergency department of the first affiliated hospital of wenzhou medical university from July 2009 to May 2015. According to the outcome of patients, we distributed the patients to death group (31 cases) and survival group (146 cases) , compared the clinic data and using multivariate analysis with Logistic regression to prognosis factors.
Results:There were 177 cases in total, with 146 survivors (82.5%) and 31 deaths (17.5%) . In which 102 cases (57.6%) had chronic underlying diseases. There were 28 cases of pesticide poisoning in the death group, and the fatality rate of pesticide poisoning was 23.5%. The mortality rate was 12.8% in the 60-69 years-old group (11/86) , 20% (13/65) in the 70-79 years-old group, 26.9% (7/26) in the 80-89 years-old group. The most common reason of poisoning was intentional ingestion, with 100 cases (56.5%) . The tract of the poisoning was mainly in digestive system, including 148 cases (83.6%) . The PSS score and APACHE-II score were 2.97±0.18 and 19.8±2.8 in the death group, 2.27±0.81 and 12.8±5.3 in the survival group. Compared with the survival group, poison (pesticides or non) 、poisoning route、cause of poisoning、PSS score、APACHEⅡ score have significant difference in death group (P<0.05) . Poison (pesticides or non) 、PSS score、APACHEⅡ, were the independent risk factors of poor prognosis.
Conclusion:Most of the elderly patients with acute poisoning have one or more chronic underlying diseases, the digestive tract ingestion and pesticide poisoning are more common. The fatality rate of the old patients is significantly higher than that of non elderly poisoning. Type of toxications, PSS score and APACHE-II score are the prognostic factors in elderly patients.
