Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The NTC will be inserted percutaneously by 2 trained nephrology specialists with dynamic ultrasound guidance and a modified Seldinger technique; duration of the procedure is 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 assessed by a trained vascular nurse who will be function as an observer during the procedure and register the adherence to the established protocol.

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.

Outcomes
Primary outcome [1] 332547 0
To compare the use of economic and human resources to solve the composite early complications episodes when NTC the tip is placed in the second intercostal space vs the fourth intercostal space.

The episodes of dysfunction, episodes of repositioning and episodes of relocation of the NTC will be assessed as a composite primary outcome.

Dysfunction is defined as the impossibility of the NTC to provide adequate blood flow (>250 mL/min), assessed by review of medical records.

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, assessed with an anteroposterior radiography.
Timepoint [1] 332547 0
48 hours post-catheter placement.
Secondary outcome [1] 413876 0
To compare the use of economic resources to solve the early complications derived from the appearance of combined episodes of dysfunction, repositioning and relocation of the CNT when the tip is placed in the second intercostal space vs the fourth intercostal space.

The measurement of the use of economic resources will be determined as a composite outcome considering the cost, measured in US dollars, of the use of extra material to correct combined episodes of dysfunction, repositioning, relocation of NTC for hemodialysis, the extra cost involves the sum of NTC, chest radiography, the extra material to place the NTC, will be determined by review of medical records. In our setting, the cost of a NTC for hemodialysis is US$100, the cost of a chest radiography is US$25, and the cost of the material to place the NTC is US$30.
Timepoint [1] 413876 0
48 hours post-catheter placement.
Secondary outcome [2] 413877 0
To compare the use of human resources to solve the early complications derived from combined the appearance of episodes of dysfunction, repositioning and repositioning of the CNT when the NTC tip is placed in the second intercostal space vs the fourth intercostal space.

The measurement of the use of human resources will be evaluated as a composite outcome considering the use of time measured in minutes necessary to correct the the combined episodes of dysfunction, repositioning, relocation of NTC for hemodialysis, by the nursing and medical staff. This will be determined by review of medical records.

Time in minutes used by the doctor to solve the complications derived from the placement of the hemodialysis CNT, will be determined by review of medical records.

Time in minutes used by the nurse to solve the complications derived from the placement of the hemodialysis CNT, will be determined by review of medical records.

Statistical methods / analysis
The calculated sample was determined by the ratio difference formula resulting in 116 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 Tunneled Catheters (NTC) for hemodialysis are vital as vascular venous access. The accepted depth for the average insertion may guarantee the correct position of the tip of the CNT and does not prevent the indiscriminate use of resources used for its placement.

The study hypothesis is the use of economic and human resources derived by NTC placement early complications in patients with urgent need of Hemodialysis is reduced when the NTC is placed in the second intercostal space compared to the fourth intercostal space.

The study includes patients who need NTC placement to perform emergency hemodialysis. The selection criteria were: patients >18 years old who had accepted the placement of the CNT and needed emergency hemodialysis; patients who have signed the informed consent; and patients who can remain seated for anteroposterior chest radiography. The objective is to compare the use of economic and human resources used in two methods of CNT placement for Hemodialysis. The main outcome is the use of human and economic resources derived from the inadequate placement of the NTC when the tip of the NTC is placed in the second intercostal space (2ICS) or fourth intercostal space (4ICS). The length of the CNT tip placement depth was randomized by a true reported random number generator and split into two groups by measuring the distance between 2ICS or 4ICS, and the catheter entry point, measured in centimeters with a sterile tape measure prior to placement.
