Some studies indicate that vital signs such as blood pressure, heart rate, respiration rate, body temperature correlate with each other. However, no study has rigorously confirmed the correlations between vital signs due to study limitations. The aim of this study is to determine the relationship of pain to vital sings and to assess its clinical utility in ureter stone patients.
All 371 patients with ureter stone admitted to the Emergency Department (ED) at Kyung Hee University Hospital from September 1, 2005 to August 31, 2006 were prospectively involved in our study. We recorded vital signs of all patients 3 times every 10 minutes before analgesic injection and determined mean values. We analyzed the data by using the SPSS 13.0 statistics program.
The means for systolic and diastolic blood pressure, heart rate and respiration rate were significantly different in pain score (p<0.05), but were not different by body temperature. Correlations of pain grade to vital signs were calculated, and blood pressure, heart rate and respiration rate showed positive correlation with pain grade (p<0.05). In multivariate analysis by general linear analysis, only systolic blood pressure and respiration rate were significantly associated with pain scores (p<0.05).
In general, we have a tendency to underestimate the importance of the respiration rate relative to blood pressure, heart rate, and body temperature except in special circumstances, such as COPD or asthma exacerbation. Self-reported pain scores of patients correlate with vital signs, especially blood pressure and respiration rate.
Key words: Respiration rate, Vital signs, Pain, Urinary calculi
