Abstract
It was demonstrated that; the most common complications of pediatric strabismus surgery were emergence agitation (EA), postoperative nausea and vomiting (PONV), and postoperative pain. Aim of this study: to compare the effectiveness of pre-operative injection of dexmedetomidine or dexamethasone in subtenon block in conjunction to general anesthesia under bupivacaine anesthesia on, reducing pain in the immediate post-operative period (VAS), emergence agitation, hemodynamic stability, attenuating airway reflex to extubation in patients undergoing strabismus surgeries. Patients and methods: Pediatric patients prepared for strabismus surgeries in the period between 2020 and 2022. Methods: This study was conducted at Mansoura Ophthalmology Centre on patients aged between 6 and 12 years of either sex, underwent abdominal surgery. Exclusion criteria include : parents refusal, and allergy to any of the drugs used. This study was conducted on a total of 80 patients who were divided into two groups (n=40). group I received subtenon mixture of, bupivacaine0.5% (2 ml) and dexmedetomidine (0.5 μg/kg) (1 ml) and group II received subtenon bupivacaine0.5% (2 ml) and dexamethasone (1 ml) (0.5mg). Results : group II was associated with a significant increase in VAS score, total paracetamol, Ramsay Sedation score, and mean PAED compared to group I. By analyzing and processing the results obtained our study we concluded that: Dexmedetomidine as an adjuvant to subtenon block in conjunction to general anesthesia was demonstrated to be associated with promising outcomes in terms of pain reduction, lower analgesic requirement, VAS score and emergence agitation with no effect on hemodynamic parameters compared to dexamethasone.
