Study Description
Brief Summary
This methodological research is aimed to examine the effectiveness of the methods used to estimate the internal length of the nasogastric tube and to determine the most reliable method for correct placement of the nasogastric tube in adults.
The study will be carried out between 01 September 2022 and 01 September 2023 with 155 patients who hospitalized in the anesthesia and reamination intensive care and general intensive care units of Aydın Adnan Menderes University Application and Research Hospital.

Research data will be analyzed in SPSS (Statistical Package for Social Sciences) for Windows 25.0 statistical package program. Descriptive statistical methods (number, percentage, mean, standard deviation) will be used in the evaluation of the data. The comparison between the methods used in the measurement of the nasogastric tube (NEX, CoNEX, XEN+10 cm, GWNUF, EXU-NE) and the results of the radiological evaluation (reference method) will be made with Chi-square analysis.

Detailed Description
This research is a methodological study in a single-blind randomized controlled experimental model. This research is aimed to examine the effectiveness of the methods used to estimate the internal length of the nasogastric tube and to determine the most reliable method for correct placement of the nasogastric tube in adults.
The study will be carried out between September 2022-September 2023 with 155 patients who hospitalized in the anesthesia and reamination intensive care and general intensive care units of Aydın Adnan Menderes University Application and Research Hospital.
A total of five internal tube length measurement methodologies will utilized to determine the length of NGT to be placed on the patient. These methods are CoNEX measurement method (Experiment 1), XEN+10 cm measurement method (Experiment 2), GWNUF measurement method (Experiment 3), EXU-NE Method measurement method (Experiment 4) and NEX measurement method (control). To collect data, a ''Case Report Form'' is carried out. This form consisted of 17 items regarding each patient's descriptive characteristics (age, gender, etc.), data concerning their illness and treatment (duration in intensive care, medical diagnosis, existing chronic disease, level of consciousness, drugs being administered) as well as data about the NGT intubation (type and gauge of NGT, observation for signs of respiratory distress, other complications, etc.).Patient information will obtained from their medical records. All the NGT placements will conducted by the same researcher under the supervision of the other two researchers. Following NGT insertion, "abdominal x-ray"(gold standard)" reference method will used to confirm the placement of NGT.
Descriptive statistical methods (number, percentage, mean, standard deviation) will be used in the evaluation of the data. The comparison between the methods used in the measurement of the nasogastric tube (NEX, CoNEX, XEN+10 cm, GWNUF, EXU-NE) and the results of the radiological evaluation (reference method) will be made with Chi-square analysis. Statistical significance will be accepted as p<0.05.
