Abstract
Nutritional support is very important for critically ill adult patients. Nasogastric tube (NGT) and Orogastric tube (OGT), are very important for critically ill patients .OGT/NGT can be used for initiation of enteral feeding, medication administration and lavage fluid aspiration. Insertion of the NGT/OGT is done currently as a blind placement at the patient’s bedside. Prior enteral feeding, and medication administration the NGT/OGT placement must be verified. In many health care institutions, placement verification is done through chest x-ray. This method is costly and exposes patients to unnecessary radiological exposure increasing patient’s harm.
There have been many research studies with different methods and technology devices to determine the safest, and less expensive, method for placement verification of nasogastric/ orogastric (NGT/OGT) tube. Insertion of NGT/OGT is a high risk procedure, considering the possible complication of misplacement. The placement of NGT/OGT inserted for enteral feeding require accurate verification for prevention of multiple complications. Even during the insertion, there is a risk of aspiration if patient is vomiting at the time of procedure.
Regardless of the institution, caring for the patients with NGT/OGT, is an important responsibility for nurses, and require many interventions as : carefully insertion of the NGT/OGT, safely removal of it when it is not needed, assessing the correct placement in the stomach, measuring and securing the tubes and, monitoring the patient throughout the process.. Patient outcomes are influenced by nurses’ interventions and management of the nasogastric tube. It is important that nursing care follow the best evidence based practice available. Health care providers are ensuring that all the adult patients with NGT/OGT in critical care are safe, and are receiving evidence based practice care across the country over the course of their illness. However there have been an increased number of incidents and misplacement of NGT/OGT in adult hospitalized patients with serious complications. Registered Nurses around the country value the application of scientific evidence-based practice to guide and improve the quality of healthcare for better outcome.
Recent evidence suggests that official statistics greatly underestimate the occurrence of complications from misplaced nasogastric (NG) tubes, even when detected (Weinberg & Skewes 2006). NGT may be misplaced in the brain, especially in patients with maxillofacial trauma (Pillai et al 2005), or after endoscopic skull base surgery (Hanna et al 2012). Inadvertent placement of a NGT into the brain of a patient with a traumatic defect in the cribriform plate is a problem that has been recognized for decades but reports of this complication still occur (Rahmi et al 2005). Serious complications were associated with the malposition in 14 (28 %) of the patients ; these included eight instances of pneumothorax that required chest tubes and one that required endotracheal tube and intubation, as well as five cases of pneumonia( Taylor, 2014).
There are variety of practices related to the accurate method of verifying the NGT/OGT placement.
The purpose of this systematic review is to conduct a comprehensive research to reconcile the evidence and determine what method for verification of nasogastric/orogastric (NGT/OGT) tube placement reduce complications in adult hospitalized patients.
Inclusion Criteria: This systematic review will incorporate studies related to hospitalized patients who require nasogastric tube for enteral feeding, medication or abdominal decompression. In those patients placement verification of NGT/OGT is very important for patient safety.
Data collection: All project data will be extracted from research studies using a modified Joanna Briggs Institute (JBI) data extraction form
Conclusions & Implications: Cortrak Enteral Access System, is a new electromagnetic tube placement device that could eliminate the need for x-ray placement verification of NGT/OGT. The review of literature research revealed the evidence that support the use of Contrak Enteral Access System (Creel et al, 2007). Cortrak enteral electromagnetic tube feeding is a new practice for NGT/OGT placement verification. The use of an electromagnetic tube placement device, such as Cortrak, is potentially the safest and most efficient practice method in current healthcare practices (Roberts et al, 2007). The Cortrak 2 has FDA clearance to be used in confirming tube tip location in lieu of X-ray.
This, in effect, leads to reduced cost and improved patient safety (Sackett et al, 2007). The research literature suggests that the use of Cortrak enteral electromagnetic tube placement device would be more beneficial than existing practices.
This Cortrak Enteral electromagnetic tube feeding placement device needs to be implemented and standardized in hospital settings. The research shows that twelve aspiration events occurred among 276 patients (prevalence, 4.4%; 95 % confidence interval, 2.2% to 7.6%). In this study the incidence of aspiration as 2.4 % per 1000 tube-feeding days (95% confidence interval, 1.2 to 3.9 per 1000) (Mullan & Roubenoff, 1992). Electromagnetic placement devices have been suggested as a replacement for radiographic confirmation of feeding tube placement at the bedside, although adverse outcomes have been reported, implying that a high level of user expertise may be necessary to obtain consistently positive results (Metheny,2014).
