Several theories have been proposed, the most consistent being that it acts in a similar fashion to NSAIDs by the inhibition of the cyclo-oxygenase pathways. However, paracetamol lacks both the peripheral anti-inflammatory and anti-platelet response seen with NSAIDs28. More recently, it has been suggested that paracetamol may also be linked with both direct and indirect stimulation of the cannabinoid, nitric oxide synthase, and serotonergic pathways. Patients satisfying the inclusion criteria were selected during the study period from the operation register on a daily basis. After obtaining a written informed consent, sixty patients were recruited for this study. They were allocated into two groups of 30 each. 10 patients in group D and 08 patients in group P complained of nausea, none of the patients in either group had vomiting, bradycardia, and hypotension

In laparoscopic surgeries, marked hemodynamic changes occur due to the effect of absorption, positioning of the patient, anesthetic agents and pneumoperitoneum. When the intra-abdominal pressure is < 10mmHg, hemodynamic alteration is not significant. Significant alteration in hemodynamics occurs, when the intra-abdominal pressure is > 10 mmHg after insufflation. When the intra-abdominal pressure is >10mmhg, it will cause inferior vena cava compression and pooling of blood in the lower extremities, which decreases the venous return to the heart thereby reducing the cardiac output. On receiving patient in operating room, the patient monitoring included electrocardiogram (ECG), noninvasive blood pressure (NIBP), heart rate (HR), oxygen saturation (SPO2). The baseline HR, NIBP, SpO2 scores were recorded. The hemodynamic parameters taken into consideration were the heart rate, systolic blood pressure, diastolic blood pressure, mean arterial blood pressure. Mean values of these parameters were analyzed from the baseline, every minute for the first 10 min thereafter for every 5 min till the end of surgery. The heart rate was significantly lower in dexmedetomidine group during the initial 10 min during infusion, lowest mean of 79.53±13.08, none of the patients from either group had bradycardia requiring atropine. Mean value of HR was higher in paracetamol group compared to dexmedetomidine group till 1 h postoperatively. Using preanesthetic dexmedetomidine 1μg/kg infusion followed by 0.5 μg/kg/h showed there was no difference in MAP between the groups, but heart rate of dexmedetomidine group was lower compared to the control group.
