Introduction: Post operative pain causes complications and dissatisfaction in patients. The aim of this study was to compare the perceprion of pain from the viewpoint of nurses, patients and surgeons and its relationship with analgesics at post open prostatectomy.

Methods: Perceprion of pain from the viewpoint of the nurses, doctors and patients was assessed by questionnaire. Validity and reliability has been approved by Faculty of Isfahan University of Medical Sciences. Pain intensity is measured by Visual analogue scale (VAS). The type and amount of analgesics were recorded by the cheek List.

Results: Results showed that most of physicians (%72.2), nurses (%72.3) and patients (%90), have moderate understanding to pain. The majority of nurses (%53.3) rated pain as moderate, while the majority of patients (%83.3) rated pain as severe. The majority of patients (%76.7) received Pethidine. Chi-square showed a significant difference between the Patients' perception of pain and intensity of pain (P ≤ 0.05) and significant difference between Nurses' perception of pain and intensity of pain (P ≤ 0.05).Chi square showed significant relationship between patients' perception of pain with analgesic but did not show any significant relationship between nurse s' perception of pain with analgesic and the doctor s' perception of pain with analgesic (P ≤ 0.05).

Conclusions: Postoperative pain control, reduction of pain and patient satisfaction were considered. The findings showed that nurse s’ and doctor s' perception of pain was moderate. Since most doctors and nurses haven’t studies about pain, it is recommended that training should be given to them.
