Abstract
BackgroundAlthough many techniques have been introduced to facilitate nasogastric tube (NGT) insertion using anatomic landmarks and a group of devices, there is a lack of general consensus regarding a standard method. The current study purposed to investigate if SORT maneuver (sniffing position, NGT orientation, contralateral rotation, and twisting movement) increases the success rate of NGT correct placement versus neck flexion lateral pressure (NFLP) method.MethodsA randomized controlled trial study was conducted in two university affiliated intensive care units (tertiary referral center). Three hundred and ninety-six critically ill patients older than 18 years of age were randomly divided into SORT (n = 200) and NFLP (n = 196) groups. The technique was classified as “failed” after the third unsuccessful attempt. Patient characteristics, success rate for the first attempt, time required for the successful first attempt and overall successful insertion time, various complications including kinking, coiling and bleeding and ease of insertion were noted as main outcomes measured.ResultsEase of insertion was significantly better in the SORT group compared to the NFLP group (P < 0.001). The number of failed attempts was significantly higher in the NFLP group (7.5%) vs the SORT group (3.0%) (P = 0.046). The pattern of complications was not different between two study groups (P = 0.242). The odds of stage II (odds ratio (OR) = 49.9; 95% confidence interval (CI) 25.2 to 98.6), stage III (OR = 67.1; 95% CI 14.9 to 302.8)) and stage IV (OR = 11.8; 95% CI 3.4 to 41.2) ease of insertion were much higher in NFLP compared to SORT group, after adjusting for age and body mass index (BMI). The odds of failure was not significantly different in NFLP group compared to SORT group (OR = 2.3; 95% CI 0.85 to 6.3), after adjusting for age and BMI.ConclusionsSORT technique may be considered as a promising method for successful NGT insertions in critically ill patients. However, more trials are needed to confirm the results of this study. The decision must account for individual patient and clinical factors and the operator’s experience and preference.Trial registration: The study was registered at government registry of clinical trials in Iran (http://www.IRCT.ir) (number: IRCT20091012002582N18, 13 March 2018)

SORT technique may be considered as a promising method for successful nasogastric tube (NGT) insertions in critically ill patients
Patients were randomly divided into two groups using a balanced block randomization by the Research Pharmacy team; group neck flexion lateral pressure (NFLP) in which NGT was inserted for all patients with standard method (NFLP) and group SORT in which NGT was inserted through SORT maneuver
Summary
Nasogastric tube (NGT) insertion is one of the most commonly performed interventions in critically ill patients [1]. SORT is a mnemonic word for the four main steps of the maneuver, namely: Sniffing position, NGT Orientation, contralateral Rotation, and Twisting movement [13]. He recommended that the manoeuver could be of assistance in trans-esophageal echocardiography probe insertion. The present study was carried out to compare NGT insertion by SORT maneuver with neck flexion lateral pressure (NFLP) in critically ill patients admitted to ICU. The current study purposed to investigate if SORT maneuver (sniffing position, NGT orientation, contralateral rotation, and twisting movement) increases the success rate of NGT correct placement versus neck flexion lateral pressure (NFLP) method
