Intervention/exposure

Study type

Interventional

Description of intervention(s) / exposure

The NTC will be inserted percutaneously by 2 trained nephrology fellows with the guidance of ultrasound and a modified Seldinger technique; duration of the procedure 30- 45 minutes and will be realized on an sterile environment on a designated procedure room.

The placement of the NTC tip will be randomized to the classic method located in the fourth intercostal space (4ICS) and the intervention method located in the second intercostal space (2ICS).

The Intervention position group (IG). In this group, the NTC tip will be inserted to be located on the second intercostal space (2ICS). The distance between 2ICS and the catheter entrance point (located at an imaginary traversal line that crosses the cricoid cartilage), will be measured in centimeters with a measure tape and defined as the length at which the NTC should be inserted.

The adherence to the intervention will be assed by a trained vascular nurse who will be function as an observer during the procedure and register the adherence to the established protocol.

Intervention code [1]

Treatment: Devices

Comparator / control treatment

The Classic position group (CG). In this group, the NTC tip will be inserted to be located on the fourth intercostal space (4ICS), using the classical anthropometric measurement; this is the distance between 4ICS and the catheter entrance point (located at an imaginary traversal line that crosses the cricoid cartilage), which will be measured in centimeters with a measure tape and defined as the length at which the NTC should be inserted.

Control group

Active

Outcomes

Primary outcome [1]

The number of dysfunction, repositioning and relocation composite episodes due to NTC tip placement on the second intercostal space versus the fourth intercostal space.

Disfunction is defined as the impossibility of the NTC to provide adequate blood flow (>250 mL/min).

Repositioning is defined as the need to accommodate the catheter because the tip of the NTC, assessed by anteroposterior radiography, is below the atrio-cava junction.

Relocation is defined as the need to remove and place a new NTC, because the tip of the NTC was lodged 1 cm above the bronchial carina, evaluated with an anteroposterior radiography.

Timepoint [1]

48 hours post-catheter placement.

Secondary outcome [1]

The number of dysfunction episodes due to NTC tip placement on the second intercostal space versus the fourth intercostal space.

Disfunction is defined as the impossibility of the NTC to provide adequate blood flow (>250 mL/min).

Timepoint [1]

48 hours post-catheter placement.

Secondary outcome [2]

The number of repositioning episodes due to NTC tip placement on the second intercostal space versus the fourth intercostal space.

Repositioning is defined as the need to accommodate the catheter because the tip of the NTC, assessed by anteroposterior radiography, is below the atrio-cava junction.

Timepoint [2]

48 hours post-catheter placement.

Secondary outcome [3]

The number of relocation episodes due to NTC tip placement on the second intercostal space versus the fourth intercostal space.

Relocation is defined as the need to remove and place a new NTC, because the tip of the NTC was lodged 1 cm above the bronchial carina, evaluated with an anteroposterior radiography.

Timepoint [3]

48 hours post-catheter placement.

Efficacy

Statistical methods / analysis

The calculated sample was determined by the ratio difference formula resulting in 153 patients, taking as reference a power of 80% and alpha of 5. The data will be reported as mean and standard deviation or median and range, accordingly to data normality distribution. To compare the standard deviation, a Fischer test will be applied in the correlation of coefficients. Confidence intervals of 95% will be used. Evaluation of qualitative variables through Chi square (tables 2x2 or 2x3) where the difference was established when the p was less than or equal to 0.05.

Summary

Brief summary

Non-tunnelled catheters (NTC) for hemodialysis are an indispensable vascular access in patients in need of hemodialysis, especially urgently. The insertion method used for the placement of NTC can reduce serious complications. Authors design a randomized clinical trial with adult patients of the University Hospital, of the Autonomous University of Nuevo Leon, Monterrey, Mexico, who required emergency hemodialysis by NTC. The calculated sample size is 153 patients. 

The NTC will be inserted percutaneously by 2 trained nephrology fellows with the guidance of ultrasound and a modified Seldinger technique. The placement of the NTC tip will be randomized to the fourth intercostal space (4ICS) and the intervention method located in the second intercostal space (2ICS). 

The main outcome is to compare the number of dysfunction, repositioning and relocation composite episodes of the NTC for Hemodialysis tip placement on the 4ICS and the 2ICS.
