A clinical study On Changes in oxygen saturation, haemodynamics and ECG in patients during postoperative period undergoing abdominal surgery using different analgesic

Patient generally faces some degree of cardio-pulmonary complication, in post operative period, measuring O2 saturation, ECG changes and haemodynamics changes despites pulmonary and circulatory complication in post operative patient receiving Morphine, Tramadol and Pathedine. Patients were divided into 3 groups. Group A: Morphine Group -: Subgroup I: morphine IM, Subgroup II: morphine IV, Subgroup III: Morphine epidurally, Group B: Tramadol Group -: Subgroup I: tramadol IM, Subgroup II: tramadol IV, Subgroup III: Tramadol epidurally., Group C: Control Group-: Patients receiving Pethidine IM on demand, which is the standard practice. In each .sub group we 10 patient included (n=10).In our study we found Variables like pulse rate, systolic or diastolic or mean blood pressure, respiratory rate, changes in ECG and arterial oxygen saturation showed no statistically significant difference between study and control groups. Keeping in view all the factors considered in the present study, epidural morphine was found to be the best analgesic with very good analgesia, less sedation and hemodynamic stability with fewer side effects. Epidural Tramadol was found to be the next best. IM Tramadol was last in rating as it was a poor analgesic for intense postoperative pain, although hemodynamic and respiratory stability was good without any side effects. So we recommend epidural morphine 3mg in 10ml saline for control of postoperative pain relief
