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] 314219 0
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] 319777 0
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] 319777 0
48 hours post-catheter placement.
Secondary outcome [1] 369510 0
The number of dysfunction episodes due to NTC tip placement on the second intercostal space versus the fourth intercostal space.

Timepoint [1] 369510 0
48 hours post-catheter placement.
Secondary outcome [2] 369511 0
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] 369511 0
48 hours post-catheter placement.
Secondary outcome [3] 369512 0
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] 369512 0
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.
