Insertion de la sonde nasogastrique

BACKGROUND: It is often difficult to correctly place nasogastric (NG) tubes under
anesthesia. We hypothesized that simple modifications in technique of NG tube
insertion will improve the success rate.
METHODS: Two hundred patients were enrolled into the study. The patients were
randomized into four groups: control, guidewire, slit endotracheal tube, and neck
flexion with lateral neck pressure. The starting point of the procedure was the time
when NG tube insertion was begun through the selected nostril. The end point was
the time when there was either a successful insertion of the NG tube or a failure
after two attempts. The success rate of the technique, duration of insertion
procedure, and the occurrence of complications (bleeding, coiling, kinking, and
knotting, etc.) were noted.
2, analysis of variance, and Student’s t-test were used
to analyze the data.
RESULTS: Success rates were higher in all intervention groups compared with the
control group. The time necessary to insert the NG tube was significantly longer in
the slit endotracheal tube group. Kinking of the NG tube and bleeding were the
most common complications.
CONCLUSION: The success rate of NG tube insertion can be increased by using a
ureteral guidewire as stylet, a slit endotracheal tube as an introducer, or head
flexion with lateral neck pressure. Head flexion with lateral neck pressure is the
easiest technique that has a high success rate and fewest complications.Cliquez
