Abstract

|
|
The main purpose of this study is an exploration of the diurnal variation and factors that influence the perception of the postoperative pain of surgical patients following surgery. The subjects selected were 32 patients of the general surgery unit at Seoul- National University Hospital.
The patients completed an Eysenck personality scale in preoperative state and were asked to report on their pain intensty, mood, alertness, and temperature every two hours from 08.00 to 24.00 for 4 successive days.
The findings obtained from this study were as follows:
1. These postoperative pain ratings and axillary temperature were found to exhibit a reliable diurnal variation with a peak at 24.00 hours.
2. There were no significant interactions between age, sex, and the diurnal variation in pain intensity. Females and the young age-group reported more pain than males and the old-age group.
3. There was a partly significant effect of personality factor on the diurnal variation in pain intensity. Neurotics and extroverts reported more pain than stables and introverts.
4. There were highly significant correlations between pain ratings and factors, such as temperature, mood, and alertness. Higher pain ratings tended to be associated with high axillary temperature, drowsy mental state, and unpleasant mood state.
5. Pain ratings measured by sensory intensity scale and unpleasant scale were significantly correlated with those measured by graphic rating scale.
