| Summary: | Background and purpose : NLD obstraction causes chronic or acute Dacryiocytits resistant epiphora. Current treatment is DCR for persistent conection between lscrimal sac and nasal cavity. Vasocontrictor drugs are used facilitasing the operation.Materials and methods : Being approved in the ethics committee of the Mazandaran University of Medical Sciences the study performed on 57 patients ASAL, II whom were divided in to two groups; Adrenaline group, no=23 and non adrenaline group no= 34. 10-15-ml adrenalin 1/200000 was injected at surgical area, before surgery in AG. BP, PR and bleeding were recorded during before and 1, 3, 5, 10,… min during the surgery. The results were analysed using t-test, and paired t-test at a significance level of< 0.05.Results : Maximum BP was measured at 3 minuts after adrenaline injection. The average of bleeding in adrenaline group was 38.3 ml and in nonadernaline group was 49.16 ml(P=0.007). The time of surgery in adrenalin group is shorter than non adrenaline group(P=0.003).Conclusion : Althragh adrenaline decreased the bleeding during surgery and facilitated the procedure, it is potentially dangerous for patients with cardiovascular disease during DCR syrgery.
