Abstract 【Objective】To explore the correlation between mild hypothermia treatment at different temperatures and pulmonary infection in patients with cardiac arrest and recovery of cardiac rhythm through cardiopulmonary resuscitation. 【Methods】Seventy-two patients after cardiopulmonary resuscitation in our hospital were randomly divided into three groups: group A, group B and group C, with 24 cases in each group. Group A was treated with non-hypothermia, group B with 36 ℃ hypothermia and group C with 33 ℃ hypothermia. The survival rates at 2 weeks after treatment and at the time of hospital discharge in the three groups were compared, and the clinical pulmonary infection score (CPIS), sputum culture positive rate, sputum culture positive pathogenic bacteria spectrum, oxygen and index and infection indexes [Creactive protein (CRP) and procalcitonin (PCT)] on treatment 3 d and treatment 7 d were compared among the three groups. 【Results】There was no significant difference in the survival rate between the three groups after 14 days of treatment and at the time of discharge (P>0.05). The CPIS score of group C on 3 d and 7 d of treatment was lower than that of group A and group B (P<0.05). There was no significant difference in the positive rate of sputum culture among the three groups on 3 d of treatment (P>0.05). The positive rate of sputum culture on 7 d of treatment in group C was lower than that in group A and group B (P<0.05). There was no significant difference in sputum culture positive pathogenic bacteria spectrum between the three groups on treatment day 3 and treatment day 7 (P>0.05). On treatment 3 d and 7 d, the oxygen and index of group C were higher than those of group A and group B, and the levels of CRP and PCT were lower than those of group A and group B (P<0.05). 【Conclusion】The mild temperature control, which is at 33 ℃ hypothermia treatment after cardiopulmonary resuscitation, can reduce pulmonary infection, reduce the positive rate of sputum culture, increase oxygen and index, and improve the levels of CRP and PCT.
