Objective To observe the clinical efficacy of continuous blood purification (CBP) combined with conventional methods for the treatment of heat stroke (HS).
Methods Retrospective analysis was performed for clinical data of 38 patients with HS, including 6 cases in death group, 16 cases in observation group, and 16 cases in control group. The control group received conventional treatment, while the observation group was given early CBP combined with conventional treatment. Changes in vital signs such as blood pressure, respiration, heart rate, body temperature at admission and after treatment, and changes in inflammatory and biochemical indicators at 0, 24, 48 and 72 h were compared among the three groups.
Results Compared with the indicators at admission, the respiratory rate, heart rate, and body temperature decreased in both the observation and control groups after treatment (P < 0.05). The inflammatory and biochemical indicators at initial admission were higher in the observation group than in the control group (P < 0.05). However, there was no statistical significance in inflammatory and biochemical indicators between the two groups after treatment (P>0.05). There were more sinus tachycardia cases in the observation group than in the control group at admission, and the number of cases with sinus bradycardia in the observation group was less than that in the control group after treatment (P < 0.05).
Conclusion Early CBP combined with conventional treatment for HS can improve prognosis and reduce the case fatality rate.
