Aim: To compare the efficacy of blind transpyloric placement using a specifically designed nasojejunal tube (NJT) versus a standard nasogastric tube (NGT) in severe head injury (SHI).
Methods: This was a randomised trial conducted in a neurosurgical intensive care unit. Fourteen patients were enrolled with a Glasgow Coma Score (GCS) less than 8 (mean 6.8 SEM+/-0.36). Patients were randomised to receive either NJT or NGT.
Results: There was an 83% (5/6 patients) spontaneous jejunal placement rate of NJT past the ligament of Treitz. The 17% (1/6 patients) jejunal placement failure rate for NJT was due to inappropriate technique. A 100% (8/8 patients) failure of the unweighted NGTs to pass through the pylorus into the jejunum was recorded (P=0.002).
Conclusion: In SHI, the specifically designed self-propelling NJT was effective in spontaneous transpyloric placement past the ligament of Treitz within 12h of introduction into the gastric cavity. The standard un-weighted NGT was ineffective. Additional studies are warranted to determine the clinical efficacy of this self-propelling NJT.

A Two-Stage Bedside Intubation Method to Improve Success Rate of Post-pyloric Placement of Spiral Nasoenteric Tubes in Critically Ill Patients: A Multi-Center, Prospective Study.
Front Med (Lausanne)

Department of Intensive Care Unit of Cardiovascular Surgery, Guangdong Cardiovascular Institute, Guangdong Provincial People's Hospital, Guangdong Academy of Medical Sciences, Guangzhou, China.
Backgrounds: Prokinetic agents could improve the success rate of post-pyloric placement of self-propelled spiral nasoenteric tubes (NETs), and bedside blind technique might apply as a rescue therapy subsequent to spontaneous transpyloric migration failure. The objective of this study was to investigated the validity and safety of these two bedside intubation methods as a sequential procedure for post-pyloric placement of spiral NETs in critically ill patients.
Methods: The multicenter, prospective study was conducted in intensive care units of four tertiary hospitals (June 2020 to January 2021).

Objective: This study sought to quantify the learning curve for the blind bedside postpyloric placement of a spiral tube in critically ill patients.
Methods: We retrospectively analysed 127 consecutive experiences of three intensivists who performed comparable procedures of blind bedside postpyloric placement of a spiral tube subsequent to failed self-propelled transpyloric migration in a multicentre study. Each intensivist's cases were divided chronologically into two groups for analysis.

Background: Various special techniques for blind bedside transpyloric tube placement have been introduced into clinical practice. However, transpyloric spiral tube placement facilitated by a blind bedside method has not yet been reported. The objective of this prospective study was to evaluate the safety and efficiency of blind bedside postpyloric placement of a spiral tube as a rescue therapy subsequent to failed spontaneous transpyloric migration in critically ill patients.

Background: Transpyloric feeding tubes (TPT) are often recommended in critically ill children. Blind tube placement, however, can be difficult, be time-consuming, and incur multiple radiation exposures. An electromagnetic device (EMD) is available for confirmation of successful placement of TPTs.

Background: Enteral feeding tubes for preterm infants may be placed in the stomach (gastric tube feeding) or in the upper small bowel (transpyloric tube feeding). There are potential advantages and disadvantages to both routes.
Objectives: To determine the effect of feeding via the transpyloric route versus feeding via the gastric route on feeding tolerance, growth and development, and adverse consequences (death, gastro-intestinal disturbance including necrotising enterocolitis, aspiration pneumonia, chronic lung disease, pyloric stenosis) in preterm infants.
