Background: With increase in incidence of gallbladder stone disease, the laparoscopic cholecystectomy is most preferred surgical technique. Laryngoscopy and peritoneal gas insufflation leads to hemodynamic stress response and pain during and after the procedure. Multimodal analgesia is recommended to reduce the stress response and prevent the post laparoscopic pain. Intravenous paracetamol and intravenous dexmedetomidine are both effective components in respect of multimodal analgesia.
Aims and Objectives: The aim of this study was to compare and evaluate the effects of intravenous paracetamol and dexmedetomidine alone and in combination as part of multimodal analgesia on perioperative hemodynamics and post-operative analgesia.
Materials and Methods: One hundred and five patients between the of age 18–60 years posted for laparoscopic cholecystectomy were randomly assigned to three groups (n=35). Before induction patients in Group D received dexmedetomidine 0.5 μg/kg/h and patients in Group P and Group P+D received 1 g paracetamol infusion over 15 min. Intraoperatively as continuous infusion patients in Group D and Group P+D received dexmedetomidine 0.2 μg/kg/h and Group P received 0.2 mL/kg NS until the removal of gallbladder. Perioperative hemodynamic variables, postoperatively, the need for rescue analgesia and any complications or side effects were recorded, compared, and analyzed.
Results: Intraoperative hemodynamic variables were significantly higher in Group P compared to Group D and Group P+D (P<0.05). Prolonged rescue analgesia found in Group P+D (9.06±1.16 h) then Group D (5.52±1.22 h) and Group P (4.35±0.99 h), respectively, which was strongly significant among the groups (P<0.0001).
Conclusion: Our study concluded that the combination of paracetamol and dexmedetomidine maintains the better hemodynamic stability and prolonged the duration of analgesia, with the benefit of high patient satisfaction. In addition, there was significantly less post-operative bradycardia and shivering.
