Fresh Mature Thumb Tube __LINK__
Reported complications with button gastrostomy catheters are comparable to those described for other gastrostomy tubes. Serious complications such as gastrocolocutaneous fistula and peritonitis have been reported. Fatalities have been described with underestimated mature tract length leading to tract rupture on filling the retention balloon.13

One possible complication with IGG is inadvertent insertion of thegavage tube into the trachea (tracheal obstruction) rather than into theesophagus. If this occurs, the rabbit may cough, choke and struggleviolently, and the tube should be immediately withdrawn. The rabbit shouldthen be allowed a few moments to recover before a fresh attempt is made.Insertion of the gavage tube into the trachea may not always be evident, sothe operator should be very careful. Passage of the feeding tube through theesophagus is usually smooth and gentle, whereas if the tube is passed throughthe trachea, the striations of the cartilaginous rings may be felt, as wellas increased resistance. Other possible complications can includeregurgitation (a consequence of which may be aspiration pneumonia at a laterstage) and ingestion of the tubing, which usually occurs because of poor IGGtechnique or if the incorrect size of feeding tube is used. If regurgitationoccurs, the feeding tube should be immediately removed and the rabbit placedin a cage to allow it to clear the contents on its own. The rabbit willprobably shake its head from side to side in an attempt to clear its airway.Afterwards, staff members should scan the cage using a Geiger counter toassess whether any radioisotope splashes occurred, in which case the areashould be decontaminated.
Although rabbits generally tend to reject any substances placed intheir mouths, small volumes (2-3 ml) of liquid can be administered relativelyeasily by syringe feeding. In this case, the restrainer places one hand overthe rabbit's poll, with the fingers and thumb holding the maxillarybones on either side (9). The operator places the tip of a needlelesshypodermic syringe over the diastema and into a corner of the mouth (9) andslowly injects the substance, much the same as would be done for a cat ordog. Unpleasant-tasting liquids are usually most easily administered usingIGG (10) with a pediatric feeding tube or by passing a stomach tube throughthe nares (11). IGG is often used to administer precise volumes of testsubstances. This method should be used only when syringe feeding or othersimpler methods of oral administration are ineffective and for theadministration of hazardous test substances (radioisotopes, infectiousagents), as is common in research settings and drug trials. IGG is used notonly in research, but also within the veterinary clinical setting to medicatesick companion animals and to provide supplementary nutrition to anorecticanimals. 041b061a72
