[Simple and rapid technique of intubation for collection of jejunal secretions].
This study was proposed to introduce a new and fast technique of aspiration to obtain samples of the small bowel juice. The utilization of a guide wire placed within the main probe lumen provides more rigidity to the system. We compared the traditional technique and the new one in 40 infants. The time elapsed for intubation was shorter with the guide wire (mean 15.4 minutes) than with the traditional technique (91.0 minutes (p < 0.05). In order to make the method more feasible the positioning of the tube was assessed by the change in the colour of the intestinal fluid and by the pH measurement of the intestinal aspirate.
