CHANGE OF PULSE RATES DURING SURGICAL EXTRACTION OF MANDIBULAR IMPACTED 3rd MOLAR

ABSTRACT

Changes of human pulse rates are influenced by psychological factor as well as systemic disease. Pulse rates tend to increase in the state of fear, pain, anxiety, and excitement. We performed this study for the evaluation of psychological state during the surgical extraction of mandibular impacted 3rd molar. Total 42 patients without systemic compromised condition were selected and pulse rates were checked with pulse oximeter(Nellcor, N-180) during the initial sitting state at dental unit chair, local anesthesia, draping and operation(5-minute interval). Male patients were 22, female 20. Age ranged from 13 to 57, with a mean of 26.9. Operative time(from incision to end of suture) ranged from 4 minutes to 32 minutes, with a mean of 11.1 minutes. The most significant elevation of pulse rates were observed during draping, the next at 10 minutes after incision(P 0.05).
