Abstract
This randomized trial was conducted to assess the efficacy and recovery profile of low dose intravenous dexmedetomidine in prevention of post-sevoflurane emergence delirium in children undergoing cataract surgery. Sixty-three children aged 1–6 years were included. Anesthesia was induced with sevoflurane and airway was maintained with LMA. They were randomized to group D 0.15 (received intravenous dexmedetomidine 0.15 μg/kg), group D 0.3 (received dexmedetomidine 0.3 μg/kg), or group NS (received normal saline). The incidence of emergence delirium, intraoperative haemodynamic variables, Aldrete scoring, pain scoring, rescue medication, and discharge time were recorded. Emergence delirium was significantly reduced in dexmedetomidine treated groups with incidence being 10% in group D 0.15, none in group D 0.3, and 35% in the NS group (p=0.002). Significantly lower PAED scores were observed in D 0.15 and D 0.3 group compared to the NS group (p=0.004). Discharge time was significantly prolonged in the NS group compared to D 0.15 and D 0.3 (45.1 min ± 4.4 versus 36.8 min ± 3.8 versus 34.4 min ± 4.6), p<0.02. Intravenous dexmedetomidine in low doses (0.3 and 0.15 μg/kg) was found to be effective in reducing emergence delirium in children undergoing unilateral cataract surgery.
