WCN25-1583 PREVALENCE AND RISK FACTORS OF INTRADIALYTIC HYPERTENSION IN MALAYSIAN HAEMODIALYSIS PATIENTS: A MUTLI-CENTRE OBSERVATIONAL STUDY

52.29AE14.32 yrs. in Non HD group Vs. 54.83AE13.19yrs for HD group.eGFR preprocedure was 29.19AE34.85ml/min in non HD group whereas 7.87AE8.47ml/min in HD group.eGFR at 1 month and 3 months' post deobstructive procedure were not significantly different in both groups (Non HD group 38.02AE29 and 32.49AE23.96vs HD group 33.82AE28.37 and 34.96AE31.08respectively).Amongst all comorbidities studied, presence of CKD (71.22% in HD group whereas 41.58% in non HD group) and smoking significantly influenced outcome.Uremic symptoms were the most common cause to initiate HD {94.96%}.Hyperkalemia was the single important indicator for need to dialyze patients {14.74% in non HD group vs 30.72% in HD requiring group}.Interestingly 3 patients of non HD group required dialysis within 1 month of deobstruction whereas 72.66% patient in the HD group did not require dialysis after procedure.15.82 % patient required #3 session dialysis after procedure and < 5% required > 3 session HD post procedure.Need for HD influenced Anesthesia requirement {Local 47.48% in HD group vs 31.58% in Non HD group, 5.04% spinal in HD group vs 17.37% in non HD group}.There was overall increased perioperative bleeding in non HD requiring group 56.32% vs 43.17% in HD group.44% having > 500 ml blood loss vs 27.34% in HD group and Hemoglobin drop > 2 gm/dl post procedure 8.95% in non HD group vs. 13.67% in HD requiring group.Renal recovery {eGFR > 50% of preprocedure level} was not significantly different in both groups at 1 month and 3 months' post procedure.No difference in rehospitalization rates was noted within 1 month of procedure.All-cause Mortality in 6 months was also not different within 6 months of the procedure with 1 death in non HD group and 3 deaths in HD requiring group.Among the 36 patient who required dialysis only after deobstructive procedure 70% had CKD Hb< 10 gm/dl and were oliguric .Dialysis was required due to uremic symptoms in 83.3% .
