| Popis: | Objective To evaluate a new technique in which a hand-held external magnet is used to maneuver nasoenteral feeding tubes through the pylorus and into the duodenum. Design Prospective case series. Setting Critical care units and medical and surgical wards of a university-affiliated community hospital. Patients Thirty-five patients were entered into the study after the attending physician requested assistance in tube placement. Interventions A standard 12-Fr, 114-cm flexible nasoenteral feeding tube was modified by inserting a small magnet into the distal tip. The tube was inserted per nares into the stomach, using traditional technique. Next, an external magnet was placed over the right upper abdominal quadrant, at the midclavicular line to attract the tube tip along the lesser curvature of the stomach, through the pyloric sphincter, and into the duodenum. Portable abdominal radiography performed immediately after the procedure confirmed the anatomic location of the tube tip. Measurements and main results Forty-two intubations were performed in 35 patients (in seven patients, the tube had to be reinserted due to inadvertent removal or surgery). In 37 (88%) of 42 intubations, the tube was passed through the pyloric sphincter and into the duodenum on the first attempt. The mean procedure time was 15 +/- 9 mins (range 10 to 45). There were no complications related to the procedure during the study period. Conclusions This report describes a novel technique of enteral feeding tube placement, using external magnetic guidance. Transpyloric placement was achieved in 88% of cases. This reliable and convenient bedside method for rapid placement of the tube into the duodenum allows prompt and safe initiation of enteral nutrition. |
