This study investigated the effectiveness of intratracheal dexmedetomidine in reducing untoward laryngeal responses in paediatrics undergoing lower abdominal surgeries.


This trial included 60 patients divided into two groups scheduled for lower abdominal surgeries. Group D were given intratracheal dexmedetomidine at a dosage of 0.5mg/kg, while Group C received intratracheal saline (0.9%). The cough severity score, the Paediatric Objective Pain Scale for pain assessment, awareness, extubation, emergence agitation score, Ramsay sedation score and adverse effects were recorded.


There was a significant difference in the incidence of coughing severity between Groups D and C both at extubation and after five minutes of extubation (p < 0.001). The median scores of the Paediatric Objective Pain Scales and the median agitation scales of Group D were significantly lower over the first four hours (p < 0.050). The mean time to first request rescue analgesia was significantly longer in the D group than in the control group (p < 0.001). The mean total consumption of rescue analgesia in the first 24 hours postoperatively was significantly lower in the dexmedetomidine group (p < 0.050). Awareness and extubation times were comparable in both groups, and none of the subjects reported any adverse effects.


In the current study, lower abdominal surgery patients who received intratracheal dexmedetomidine at a dose of 0.5mg/kg 30 minutes before the completion of the procedure experienced smooth extubation and balanced anaesthetic recovery.
