Abstract:
Objective To study the autonomic nervous regulation function,and to study relationship between heart rate variability and severity,organ dysfunction and prognosis in patients with systemic inflammatory response syndrome (SIRS).Methods All the patients were divided into two groups:SIRS and non-SIRS according to the criteria of SIRS. The SIRS group included 100 patients and the non-SIRS group 30 patients,and the control group included 30 heathy adults. SIRS group was further divided into two subgroups:survivor and succumbed.Heart rate variability(HRV)was analyzed with the two methods of time-domain and frequency-domain.Results The SIRS group had significantly higher APACHEll scores and MODS scores(P＜0.01)and lower HRV when compared with the non-SIRS group(P＜0.05).In the SIRS group,the succumbed groupallad statistically higher APACHEII and MODS scores and lower HRV than the survivor group( P＜0.01).There was a negative correlation between the prognosis of the patients and SDNN(r=-4.68,P＜0.01), SDNN＜55 ms was the most sensitive(76.2%),and specific(76.7%),with positive predictive value(90.4%)and negative predictive value(52.6%).Conlusion The SIRS patients had lower HRV,and there was a negative correlations with the severity of disease,organ dysfunction and prognosis.HRV(SDNN)were the useful index to evaluate the prognosis of critically ill patients.
