The effects of dexmedetomidine and tramadol on post-operative pain and agitation, and extubation quality in paediatric patients undergoing adenotonsillectomy surgery: A randomized trial

Abstract

What is known and objective Adenotonsillectomies are common surgical procedures performed under general anaesthesia in childhood. Post-operative pain and agitation are complications associated with this procedure. We compared the effects of dexmedetomidine and tramadol on post-operative pain, agitation, haemodynamic parameters, and extubation quality in patients undergoing an adenotonsillectomy using sevoflurane as an anaesthetic agent. Methods Sixty paediatric patients who had undergone an adenotonsillectomy were included in this study. The patients were randomized into two groups that received either dexmedetomidine (n = 30) or tramadol (n = 30). Haemodynamic variables, extubation time, post-operative pain, agitation and adverse events were recorded for all patients. Post-operative pain was assessed with the pain point system scale (PPSS), and agitation was assessed using the Riker Sedation-Agitation Scale (SAS). Results Patients in the dexmedetomidine group had significantly lower heart rates than the tramadol group. In addition, patients in the dexmedetomidine group had significantly lower post-operative PPSS and Riker SAS scores than patients in the tramadol group. Not breathing, cough-bucking and desaturation after extubation occurred less frequently in patients who received dexmedetomidine than in patients who received tramadol. However, the time to extubation was significantly longer for patients who received dexmedetomidine. What is new and conclusion Our study demonstrated that dexmedetomidine was more effective than tramadol for mitigating post-operative pain and agitation in paediatric patients following an adenotonsillectomy with sevoflurane. Although dexmedetomidine was associated with a longer time to extubation, it was also associated with fewer complications following extubation compared with tramadol.
