Details and patient eligibility

About

The primary aim of this study is to investigate the difference in the first attempt and overall success rate of different techniques for insertion of nasogastric tube. Secondary aim is to investigate the difference of the duration of insertion using the selected technique, complications during insertion such as kinking, knotting, mucosal bleeding

Full description

Two hundred adult patients, who received general anaesthesia for elective abdominal surgeries that required nasogastric tube insertion, will be randomized by means of a computer-generated randomization order into four groups: Conventional group (Group C), head in the lateral position group (Group L), endotracheal tube assisted group (group ET) and video laryngoscope group (group MG).

Success rate of the selected technique (first attempt, second attempt and overall), duration of insertion for selected technique, complications such as kinking and mucosal bleeding will be noted.

Enrollment: 200 patients

Sex: All

Ages: 18 to 70 years old

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

200 participants in 4 patient groups

conventional technique

Active Comparator group

Description:

the nasogastric tube will be inserted gently through a selected nostril with the head being maintained in the neutral position.

Treatment:

Procedure: conventional technique

head in the lateral position technique

Experimental group

Description:

the patient's head will be turned to the right lateral position. Nasogastric tube will be inserted through the right nostril without any maneuvers of the neck.

Treatment:

Procedure: head in the lateral position technique

endotracheal tube assisted technique

Experimental group

Description:

Nasogastric tube will be inserted the trimmed 7.5 mm internal diameter endotracheal tube what cut proximal end with sterile scissors and endotracheal tube will be advanced blindly into the oral cavity to a depth of approximately 18 cm without laryngoscope together the nasogastric tube.

Treatment:

Procedure: endotracheal tube assisted technique

videolaryngoscope technique

Experimental group

Description:

Nasogastric tube was inserted transnasally and advanced into esophagus under direct vision.

Treatment:

Procedure: videolaryngoscope technique
