Barriers and facilitators to children's use of speech-generating devices: a descriptive qualitative study of mothers' perspectives.

PURPOSE: The purpose of this study was to identify barriers and facilitators to children's use of speech-generating devices (SGD). DESIGN AND METHODS: Interviews with 14 mothers were analyzed with content analysis to identify barriers and facilitators to SGD use. RESULTS: This study identified a number of specific barriers and facilitators to successful and sustained SGD use by children with complex communication disorders. PRACTICE IMPLICATIONS: Nurses can use the list of barriers and facilitators provided here as a springboard to discuss the families' experiences with device use.

Comparing bedside methods of determining placement of gastric tubes in children.

PURPOSE: The purpose of this study was to compare the accuracy and predictive validity of pH, bilirubin, and CO2 in identifying gastric tube placement errors in children. DESIGN AND METHODS: After the tube was inserted into 276 children, the CO2 monitor reading was obtained. Fluid was then aspirated to test pH and bilirubin. RESULTS: Lack of ability to obtain tube aspirate was the best predictor of NG/OG placement errors with a sensitivity of 34.9% and a positive predictive value of 66.7%. Measuring pH, bilirubin, and CO2 of tube aspirate was less helpful. PRACTICE IMPLICATIONS: Healthcare providers should suspect NG/OG tube misplacement when no fluid is aspirated.

Comparing methods of determining insertion length for placing gastric tubes in children 1 month to 17 years of age.

PURPOSE: The purpose was to compare three methods of predicting the gastric tube insertion length in children 1 month to 17 years of age: age-related, height-based (ARHB); nose-ear-xiphoid (NEX); and nose-ear-mid-umbilicus (NEMU). DESIGN AND METHODS: The design was a randomized controlled trial. Children were randomly assigned to the ARHB, NEX, or NEMU groups. Tubes placed high were considered to be misplaced. RESULTS: There were significant differences in percentages of correctly placed tubes, with ARHB and NEMU being more accurate than NEX. PRACTICE IMPLICATIONS: NEX should no longer be used as a gastric tube insertion-length predictor. Either ARHB or NEMU should be used.

Accurate localization of the position of the tip of a naso/orogastric tube in children; where is the location of the gastro-esophageal junction?

BACKGROUND: Abdominal radiographs are used to determine the location of the tip of a newly placed nasogastric tube. The precise location of the gastroesophageal junction has not been well described in the radiology literature. OBJECTIVE: To improve interpretation of radiographs taken to evaluate the location of the tip of a nasogastric tube. Using UGI barium studies, we determined the anatomical location and variability of the position of the gastroesophageal (GE) junction and the pylorus MATERIALS AND METHODS: We reviewed 200 upper gastrointestinal barium studies (50 in each of 4 age groups). We measured the vertebral levels and distance of the gastroesophageal junction and the pylorus from the spine, the vertical distance of the gastroesophageal junction from the dome of the diaphragm and the distance from the gastroesophageal junction to the pylorus. RESULTS: There is a constant location of the GE junction with no significant variation between age groups. There is a moderately constant location of the pylorus. The other measurements were very variable. CONCLUSION: The location of the GE junction is very constant, irrespective of age. Tube tips below the level of the vertebral disc between the 11th and 12th thoracic vertebra and/or more than 16 mm from the left side of the spine lie in the stomach and not the lower esophagus. Our results should help in accurate radiographic description of the location of the tip of an NG tube.

A literature review of the safety and efficacy of using propofol for sedation in endoscopy.

A 2007 survey of members of the Society of Gastroenterology Nurses and Associates identified a need for more evidence regarding sedation medications including propofol. Therefore, the Cochrane Database of Systematic Reviews, Cochrane Database of Randomized Clinical Trials, MEDLINE, CINAHL, EMBASE, and the National Guideline Clearinghouse (http://www.guideline.gov) databases were individually searched using the term propofol, limited to human, English, 2000-2009, review articles, and randomized clinical trials. A total of 46 resources contributed to this review, with emphasis on 16 studies ranging from retrospective chart reviews to double-blind, randomized controlled trials. Nonanesthesia personnel-administered propofol, including that administered by specially trained nurses under the supervision of an endoscopist, appears to be safe with minor, easily resolved, adverse events occurring in less than 1% of patients. These minor adverse events included four studies reporting hypoxemia requiring occasional intervention, three studies reporting hypotension, and two studies reporting bradycardia. No patients required tracheal intubation, and no deaths were reported.

Out of the abyss of colic: a view through the fathers' eyes.

PURPOSE: To elucidate the experience of fathers living with a colicky infant. STUDY DESIGN AND METHODS: Interpretive phenomenology using in-depth interviews with 10 fathers of colicky infants. Reiterative interview reading, repeated meaning unit sorting, going back to the literature, and discussions gave way to emerging themes. FINDINGS: The overall experience is one of "falling into and arising from the crying abyss together as a family." Four themes emerged: (a) falling in, (b) hitting bottom, (c) weaving strands to make a rope, and (d) climbing out. CLINICAL IMPLICATIONS: From their stories, fathers provide insight useful to nurses assisting families of colicky infants through a very difficult time. Nurses should talk to fathers directly about the possibility of colic, and teach both parents what it is, how long it usually lasts, and what can be done about it. Anticipatory guidance as well as discussion about colic during newborn health visits can help parents to vocalize their feelings, and learn what actions to take when the stress of colic becomes overwhelming.

The use of carbon dioxide monitoring to determine orogastric tube placement in premature infants: a pilot study.

Enteral nutrition, frequently given through gastric tubes inserted through the nose or mouth, is an important part of supportive care for children unable to maintain adequate nutrition orally. To provide safe enteral nutrition, however, correct tube position must be achieved. Capnography, a noninvasive monitoring technique designed to measure expired carbon dioxide (CO2) levels, has been used previously to identify respiratory placement of nasogastric tubes in adults; however, its use in children is understudied. The purpose of this pilot study was to determine the potential of CO2 monitoring to differentiate respiratory from gastric placement of nasogastric/orogastric (NG/OG) tubes in the youngest, most fragile children-premature infants. Immediately prior to chest radiograph, CO2 levels in 7 premature infants were measured at the open ends of both the endotracheal and NG/OG tubes by using a bedside capnography monitor. The 14 CO2 readings from the correctly placed endotracheal tubes ranged from 32 to 61 mmHg (M = 47.6 mmHg, SD = 10.0). CO2 readings were zero in all 14 correctly placed NG/OG tubes. The results of this pilot study provide evidence that capnography may be useful in differentiating respiratory from gastrointestinal tube placement in premature infants.

Important facts about intestinal feeding tube placement.

Enteral feeding is desirable when the gastrointestinal tract is functional because it allows better use of nutrients, is safer, and is more cost-effective than parenteral nutrition. Feeding through a gastric tube, however, is often not feasible in severely ill adults and children because of gastric paresis leading to recurrent episodes of gastroesophageal reflux with the risk of subsequent aspiration. Feeding into the small intestine (duodenum or jejunum) through a nasointestinal tube, therefore, is preferred. Unfortunately, no method of enteral feeding is risk free. This literature review addresses the following 10 topics: (a) the reasons why nasointestinal tube feeding is better tolerated by some patients, (b) candidates for nasointestinal tube feeding, (c) options for selecting nasointestinal tubes, (d) recommended methods for predicting the distance to insert nasointestinal tubes, (e) recommended methods for placing nasointestinal tubes, (f) how promotility medications work and whether they facilitate nasointestinal tube placement, (g) nasointestinal tube placement error rate, (h) methods of determining the internal location of nasointestinal tubes, (i) complications associated with nasointestinal tube use, and (j) other pertinent issues surrounding feeding through nasointestinal tubes. The available research evidence is summarized and recommendations for future work are suggested.

Gastric tube placement in young children.

In this study, the internal position of a nasogastric/orogastric tube was determined in 72 children, prior to an abdominal radiograph, by measuring CO2 and pH and bilirubin of tube aspirate. Fifteen of the 72 tubes (20.8%) were incorrectly placed on radiograph. Using the suggested adult cutoff of pH 5, pH of aspirate correctly predicted misplacement outside the stomach in 7/28 (25%) of children and correctly predicted correct placement in the stomach in 34 of 40 children (85%). Using the suggested adult cutoff of bilirubin > or = 5 mg/dL, bilirubin monitoring failed to identify either of two incorrectly placed tubes. In this study, using an algorithm of assuming stomach placement if the pH of aspirate is < or = 5 and obtaining an abdominal radiograph when either no aspirate is obtained or the pH is >5 would have resulted in 92% accuracy. Alternatively, obtaining an abdominal radiograph would result in nearly 100% accuracy.

Living with a colicky infant.

Infant colic is prolonged hard crying for no apparent reason in an otherwise healthy infant. The purpose of this study was to describe the parents' experiences of caring for their infants with colic. This qualitative study employed a multiple case study design using a descriptive approach through indepth interviews. Five of the interviews were conducted in person, and 10 were conducted via e-mail. One or both parents of 15 colicky infants were interviewed about their recent experiences of living with colicky infants. Three themes--crying, emotions (anger, frustration, worry, and guilt), and feelings (hopeless, helpless, isolated, and unloved) were identified. This study adds the rich description that was missing from the previous two qualitative studies of infant colic. It also adds fathers' perspectives of the experience of living with a colicky infant. Lastly, this study demonstrates that indepth interviews can be conducted via e-mail as well as in person.

Predicting the insertion distance for placing gastric tubes.

Approximately 1 million enteral tubes are placed through the nose or mouth in adults and children in the United States annually. Previous studies found gastric tube placement errors to be common. A primary issue in ensuring safe and effective gastric feeding by tube is achieving optimal tube position on insertion. The purpose of this study is to use 24 variables to develop a clinical prediction rule for gastric tube insertion distance in adults, using the internal-nares-to-distal-lower esophageal-sphincter distance. A three-variable model using gender, weight, and nose-umbilicus-flat was selected. This new model, validated using nonparametric bootstrap cross-validation, correctly predicted gastric tube insertion distance 85.3% of the time. This new model is compared to two other methods, one evidence based and one commonly used in practice, and was found to be superior. Two nomograms, one for each gender, are drawn to make this new model easier to use.

Feasibility of using kangaroo (skin-to-skin) care with colicky infants.

Infant colic affects about 20% of all infants and the cause remains elusive. Healthcare providers typically view infant colic as a minor inconvenience that is harmless to the thriving infant and will go away with time; however, parents view caring for a colicky infant as a crisis situation. The purpose of this feasibility study conducted via the internet was to examine the feasibility of implementing kangaroo care at the beginning of colicky episodes. Mothers of colicky infants began the study by completing the on-line Infant Colic Scale and recording in a baseline state-of-arousal diary for 3 days. Next, they implemented kangaroo care at the beginning of as many episodes of colic as possible for 2 weeks while recording in a second state-of-arousal diary. Then, they stopped kangaroo care for 2 days while continuing to record in the second state-of-arousal diary, and lastly they were asked how kangaroo care worked for them.Seventy-five parents of colicky infants consented to participate in this study; however, only five of them actually did. Three of these completed only the baseline state-of-arousal diary, and two completed all parts of the study. This dropout rate showed that conducting such an intervention via the internet is not a feasible approach. Because kangaroo care for infants with colic is a promising intervention and because there are no other effective treatments for most of these infants, another feasibility study is warranted using different methods. Then if results are promising, a larger clinical trial should be conducted.

Ethical and legal issues of conducting nursing research via the Internet.

In February 2001, President Clinton's Information Technology Advisory Commission reported that information technology has the potential to advance biomedical research. As nursing research via the Internet expands, important ethical and legal issues need to be addressed. The purpose of this article is to report one researcher's journey in attempting to conduct ethical and legal nursing research via the Internet. The ethical and legal issues needing attention are discussed. Potential guidelines are provided for researchers wanting to use Internet technology.

What is known about methods of correctly placing gastric tubes in adults and children.

An abdominal radiograph is considered the "gold standard" for determining the position of flexible small-bore nasogastric/orogastric tubes. However, placement must be checked frequently while a tube is in place, and the summative radiation risk of multiple radiographs, as well as their expense, make the development of adequate bedside placement-locating methods imperative. Several methods of detecting tube placement have been investigated in adults, including: aspirating gastric contents and measuring the pH, bilirubin, pepsin, and trypsin levels; examining the visual characteristics of aspirate; placing the proximal end of the tube under water and observing for bubbles in synchrony with expirations; measuring the carbon dioxide level at the proximal end of the nasogastric/orogastric tube; auscultation for a gurgling sound over the epigastrium or left upper quadrant of the abdomen; and measuring the length from the nose/mouth to the proximal end of the tube. Many researchers have already concluded simple auscultation is not a reliable method to assess tube position because injection of air into the tracheobronchial tree or into the pleural space can produce a sound indistinguishable from that produced by injecting air into the gastrointestinal tract. In adults, only pH and bilirubin of aspirate have been shown both to reliably predict tube position and to have inexpensive simple bedside tests. In children, only pH of aspirate has been shown to be reliable. Research on gastric tube placement in children is relatively new because children are challenging to study in that they are considered a vulnerable population. This review of the literature includes results of both adult and pediatric studies. Tube placement error rates varied from 1.9% to 89.5% in adults and between 20.9% and 43.5% in children.
