A comparative study of efficacy of different doses of fentanyl in the prevention of incision related tachycardia in children
Journal Title: Medpulse International Journal of Anesthesiology - Year 2017, Vol 3, Issue 3
Abstract
Background: Pain is a subjective sensation and assessment of pain during general anaesthesia is a difficult preposition. It can only be assessed indirectly by noting the features of a stress response like tachycardia and hypertension after a surgical stimulus. Skin is a very painful structure and skin incision is invariably associated with tachycardia. Objectives: We tried to determine the optimal dose of fentanyl that can provide adequate analgesia in paediatric patient. We have studied efficacy of two doses of Fentanyl, 1 and 2 mcg/Kg body weight on prevention of incision related tachycardia in children undergoing lower abdominal surgeries. Materials and Methods: Children of age group 1-5 years were randomly allocated into two groups, Group A and B. children in Group A received 1 mcg/kg of Fentanyl and those in Group B received 2 mcg/kg of Fentanyl. After induction with thiopentone sodium, all the children were given inhalational anesthesia with nitrous oxide, oxygen and halothane mixture. Heart rate was noted at different periods during surgery. Results: In both groups heart rate increased immediately after incision and the increase in heart rate was less in group B compared to group A. But this was not significant statistically. The rise in heart rate could be suppressed only partially by Fentanyl, 2 mics/Kg of body weight. Incision related tachycardia could not be suppressed entirely by either of the two doses. Conclusions: We conclude that incision related tachycardia cannot be suppressed altogether by either 1 mcg or 2 mcg/Kg dose. For adequate analgesia it is better to give 2 mcg Fentanyl per Kg body weight in children.
