- Brief Summary
Ever since its first description by Hunter in 1790, the Nasogastric tube(NGT) has become one of the most commonly used medical devices in routine practice. Insertion of NGT is an essential procedure for several abdominal and thoracic surgeries and is often performed by anesthesiologist in the operation room. Nasogastric intubation continues to present a challenge for those patients who are anesthetized and trachea intubated.
Conventional insertion of NGT has a high failure rate of almost 55% in the first pass. This is due to the multiple apertures present in the distal portion making it susceptible to kinking, coiling and knotting.The rugged wall due to apertures may cause mucosal tear leading to bleeding. Thus many methods of insertion has come into existence, but none is earmarked as the best. Freezing the NGT have been reported to increase its rigidity, thereby facilitating the insertion with ease.
The available literature suggesting a higher success rate for frozen NGT for successful placement of nasogastric tube did not convey adequately about the experience or skill level of the researcher attempting nasogastric intubation which we believe may greatly influence the first attempt success rate independent of the technique selected. Moreover, many researchers defined a successful nasogastric intubation as a positive whoosh test which may not be true.
The present study is designed to determine the success rate of nasogastric intubation with a frozen nasogastric tube by trainee resident and compare the same with the conventional insertion of nasogastric tube at room temperature.
