Abstract:
Objective:To investigate the death of patients with granulocytopenia complicated with infection after chemotherapy and the changes of vital signs before emergency treatment, and to analyze the prognosis of different vital signs on patients' prognosis and emergency treatment.Methods:This study used a case-control study method to select 211 patients with hematologic malignancies who met the inclusion criteria in two tertiary hospitals in Weifang City. The vital signs of patients were collected and the vital signs were analyzed using SPSS 17.0 software. And the statistical significance and predictive value in the emergency response group.Results:The heart rate, respiratory rate, systolic blood pressure, blood oxygen saturation and urine volume were significantly different between the survival group (112 cases) and the death group (99 cases)( t values were 11.038-177.102, P<0.01). The area under the receiver operating characteristic curve of body temperature, heart rate, respiratory rate, systolic blood pressure, and blood oxygenation saturation and urine volume were 0.547, 0.495, 0.294, 0.899, 0.988, and 0.827, respectively. The highest predictive efficiency (higher level) was observed with the change of blood oxygen saturation, and the corresponding optimal cutoff point. 0.91; between the emergency treatment group (103 cases) and the non-emergency treatment group(108 cases), the difference in heart rate, respiratory rate and oxygen saturation between the two groups was statistically significant ( t values were 5.247, 8.001, 9.066, P<0.01). The area under the receiver operating characteristic curve of body temperature, heart rate, respiratory rate, systolic blood pressure, blood oxygen saturation and urine volume were 0.581, 0.732, 0.813, 0.346, 0.102, and 0.543, respectively. Among them, the predicted value of respiratory frequency change was the highest (medium level), which was the best corresponding. The cutoff point was 27.5. Conclusions:Patients with granulocytic infection after malignant hematologic disease will have abnormal changes in vital signs before death and emergency treatment. However, different vital signs have different effects on predicting disease changes, and should focus on respiratory rate and oxygen saturation. Changes, when the respiratory rate exceeds 27 beats/min, the probability that the patient needs to implement emergency treatment such as rescue will increase. If the condition is not effectively controlled, the blood oxygen saturation is lower than 0.91, the risk of death of the patient is greatly increased.
