Comparison of femoral artery catheter suturing techniques between parallel suturing vs conventional suturing in childrens less than 12 years

INTERVENTION: Intervention1: PROXIMAL PARALLEL SUTURING: The suture will be placed parallel to the arterial catheter, taken 2 mm proximal to the wings then passing through the suture wings of the catheter to anchor it to the skin. Control Intervention1: Conventional suturing technique: The suture will be taken near the wings either perpendicular or oblique to the catheter axis, passing through the suture wings of the catheter to anchor it to the skin. CONDITION: Health Condition 1: I52‐ Other heart disorders in diseasesclassified elsewhere PRIMARY OUTCOME: To compare the incidence of femoral arterial line waveform dampening between two suturing techniques in the first 48 hours.Timepoint: 48 hours SECONDARY OUTCOME: Number of catheter manipulations or re‐adjustments required after initial placement. ; Incidence of visible catheter kinking within the study period. ; Incidence of local site complications, such as bleeding, or hematoma. ; Overall, first attempt success rate. ; Other Predictors of arterial dampening.Timepoint: 1st 48hours INCLUSION CRITERIA: Children weighing less than 12 kg undergoing cardiac surgeries requiring 22G femoral arterial line for more than 48 hours.
