Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
The internal tube length measurement methodologies will utilized to confirm proper NGT placement. A total of 5 groups will be included in the study, including 1 control (NEX measurement method) and 4 experimental groups, (Experiment 1: CoNEX measurement method, Experiment 2: XEN+10 cm measurement method, Experiment 3: GWNUF measurement method, Experiment 4: EXU-NE Method measurement method).The "gold standard" reference method will used for comparison was radiography.
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. Statistical significance will be accepted as p\<0.05.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
NEX (Control group)
Nose-ear-xiphoid measurement method (NEX), (n=31)
The distance between the patient's nose tip and earlobe will be measured first, then the distance between the earlobe and the xiphoid (NEX method) Marking will be made on the nasogastric tube according to the length obtained from the measurement, The nasogastric tube will be advanced by the researcher from the patient's nose to the point where the marking is made, Immediately after the completion of the nasogastric tube placement procedure, an abdominal X-ray will be taken to confirm the tube location, the position of the distal end of the tube relative to the gastro-esophageal junction will be measured and recorded.
Internal Tube Length Measurement Procedures for Nazogastric Tube
Different Internal Tube Length Measurement Procedures will used for the correct placement of nasogastric tube.
CoNEX
Corrected nose-earlobe-xiphoid measurement method (CoNEX), (n=31) The distance between the patient's nose tip and earlobe will be measured first, and then the distance between the earlobe and the xiphoid, The nasogastric tube length to be applied to the patient will be determined according to the formula (NEX x 0.38696) + 36.37 cm, The length determined according to the result obtained will be marked on the nasogastric tube, The nasogastric tube will be advanced by the researcher from the patient's nose to the point where the marking is made, Immediately after the completion of the nasogastric tube placement procedure, an abdominal X-ray will be taken to confirm the tube location, the position of the distal end of the tube relative to the gastro-esophageal junction will be measured and recorded.

GWNUF
Gender-weight-nose-umblikus-head flat (GWNUF), (n=31)
The patient's body weight will be measured without clothes on, When the patient is in the supine position, the distance between the tip of the nose and the umbilicus will be measured, The length of the nasogastric tube to be applied to the patient according to the formula 29.38 + (4.53 x gender) + (0.34 x distance between the tip of the nose and the umbilicus) - (0.06 x patient weight), (gender = 1 for male patient, 0 for female patient) to be determined, The length determined according to the result obtained will be marked on the nasogastric tube, The nasogastric tube will be advanced by the researcher from the patient's nose to the point where the marking is made, Immediately after the completion of the insertion procedure, an abdominal X-ray will be taken to confirm the tube location, the position of the distal end of the tube relative to the gastro-esophageal junction will be measured and recorded.

EXU-NE
The distance between the patient's xiphoid and earlobe will be measured first (Measurement 1), (n=31) The distance between the patient's xiphoid and the midline of the umbilicus will be measured (Measurement 2), The two obtained measurement values will be added (Measurement 1 + Measurement 2), The distance between the patient's nose tip and earlobe will be measured (Measurement 3), Measurement 3 value will be subtracted from the sum of Measurement 1 and Measurement 2 values, The length determined according to the result obtained will be marked on the nasogastric tube, The nasogastric tube will be advanced by the researcher from the patient's nose to the point where the marking is made, Immediately after the completion of the insertion procedure, an abdominal X-ray will be taken to confirm the tube location, the position of the distal end of the tube relative to the gastro-esophageal junction will be measured and recorded.
