Abstract

Objective: Present study was conducted to understand the effects of chronic pain on resting cardiorespiratory parameters of the patients having chronic pain of severity >3 on visual analogue score (VAS).
Materials and Methods: 50 male cases and 28 female cases were selected from the pain clinic. 58 male and 28 female age-sex matched controls were also selected in the study. The electrocardiogram (ECG), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and respiratory frequency (RF) were recorded in cases and controls.
Results: Mean SBP/DBP of male cases is lesser than the male controls (P > 0.05). Mean SBP/DBP of female cases is more than the female controls (p < 0.05). Mean SBP/DBP of male cases is lesser than female cases (P > 0.05) and the Mean SBP/DBP of male controls is greater than female controls (P > 0.05). The HR of male cases and female cases is significantly greater than the male and female controls respectively (p < 0.05). The HR of male cases versus female cases and male controls versus female controls is not different (P > 0.05). There is no difference in the RF changes in all the groups.
Conclusions: Observations reveal that the sympathetic tone has not changed much in the male cases but it is increased in the female cases indicating the loss of sympathetic tone in male cases in comparison to the female cases. However, the parasympathetic tone seems to be decreased in both male and female cases.
