Nursing practice of routine gastric aspiration in preterm infants and its link to necrotizing enterocolitis: is the practice still clinically relevant? BMC Nurs 2024; 23:333.

Abstract
The practice of routine gastric residual aspiration in preterm infants remains controversial, with conflicting evidence regarding its impact on necrotizing enterocolitis (NEC). As front-line caregivers, nurses play a vital role in gastric aspiration procedures and must be informed by evidence. This quasi-experimental nursing study aimed to assess whether gastric aspiration is clinically relevant in reducing the risk of NEC in preterm infants.A total of 250 preterm infants from two NICUs in Egypt were allocated to the gastric aspiration (n = 125) and non-aspiration (n = 125) groups. Feeding practices, gastric residuals, and incidence/severity of NEC were compared between groups according to modified Bell's criteria. Risk factors were analyzed using multivariate regression. There were no significant baseline differences between the groups. The gastric residual attributes and feeding outcomes did not differ substantially from aspiration. The overall incidence of NEC was 14-15%, with no significant differences in the odds of onset or progression of NEC by stage between the groups. Lower gestational age and birth weight emerged as stronger predictors of NEC. Routine gastric aspiration does not appear to directly prevent or reduce the severity of NEC in this population. Although gastric residuals retain clinical importance, study findings question assumptions that aspiration protects against NEC and informs nursing practice. Evidence-based feeding protocols must continually evolve through ongoing research on modifiable risk factors for this devastating intestinal disease in preterm infants.

Abstract
Background and aim Monitoring of gastric residual volume (GRV) to assess for enteral feeding intolerance is common practice in the intensive care unit (ICU) setting; however, evidence to support the practice is lacking. The aim of this study was: (i) to gain a perspective of current practice in adult ICUs in the UK around enteral feeding and monitoring of GRV, (ii) to characterise the threshold value used for a high GRV in clinical practice, (iii) to describe the impact of GRV monitoring on enteral feeding provision and (iv) to inform future research into the clinical value of GRV measurement in the adult ICU population. Methods A web-based survey was sent to all UK adult ICUs. The survey consisted of questions pertaining to (i) nutritional assessment and enteral feeding practices, (ii) enteral feeding intolerance and GRV monitoring and (iii) management of raised GRV. Results Responses were received from 101 units. Ninety-eight percent of units reported routinely measuring GRV, with 86% of ICUs using GRV to define enteral feeding intolerance. Threshold values for a high GRV varied from 200 to 1000 ml with frequency of measurement also differing greatly from 2 to 12 hourly. Initiation of pro-kinetic medication was the most common treatment for a high GRV. Fifty-two percent of respondents stated that volume of GRV would influence their decision to stop enteral feeds a lot or very much. Only 28% of units stated that they had guidelines for the technique for monitoring GRV. Conclusions Measurement of GRV is the most common method of determining enteral feeding intolerance in adult ICUs in the UK. The practice continues despite evidence of poor validity and reproducibility of this measurement. Further research should be undertaken into the benefit of ongoing GRV measurements in the adult ICU population and alternative markers of enteral feeding intolerance.

Abstract
AIM This study aimed to evaluate the effect of abdominal massage (AM) on feeding intolerance (FI) in patients receiving enteral nutrition (EN). DESIGN A systematic review and meta-analysis. METHODS We searched seven electronic databases to September 2021. STATA and RevMan were used to analyse the data. RESULTS Eleven studies were included. The results revealed that AM could significantly reduce gastric residual volume and abdominal circumference difference, and reduce the incidence of gastric retention, vomiting, abdominal distention (all p < 0.001), diarrhoea (p = 0.02) and constipation (p = 0.002) in the experimental group. One study reported the incidence of aspiration in the control group was higher, but this was not statistically significant (p = 0.07). The meta-regression analysis showed there was a statistically significant correlation between intervention personnel and gastric residual volume (p = 0.035). CONCLUSION AM could reduce the amount and incidence of gastric retention and the changes in abdominal circumference, and significantly reduce the incidence of gastrointestinal symptoms, without increasing the incidence of aspiration for EN patients. No Patient or Public Contribution.

Abstract
BACKGROUND Feeding intolerance (FI) among intensive care unit (ICU) patients undergoing early continuous enteral nutrition (EN) is related to poor outcomes. This study aimed to explore the prevalence and risk factors of FI in ICU patients. METHODS We retrospectively enrolled 1057 patients who received early continuous EN via a nasogastric tube between January 2014 and August 2019. The prevalence of FI during the first 7 days of ICU stay was calculated, and the risk factors were investigated using multivariate logistic regression analysis. RESULTS The prevalence of FI during the first 7 days of ICU stay was 10.95%. FI occurred in 159 of 1057 (15.04%) patients on ICU day 2, 114 of 977 (11.67%) patients on ICU day 3, and 86 of 715 (12.03%) patients on ICU day 7. Mechanical ventilation (MV) (odds ratio [OR]: 1.928, 95% confidence interval [CI]: 1.064-3.493, P = 0.03) was an independent risk factor for FI defined by a gastric residual volume (GRV) of 200 mL and/or vomiting, and acute renal failure (OR: 3.445, 95% CI: 1.115-10.707, P = 0.032) was an independent risk factor of FI defined by a GRV of 500 mL and/or vomiting. Continuous renal replacement therapy (CRRT) was an independent predictor regardless of the FI defined by a GRV of 200 mL (OR: 2.064, 95% CI: 1.233-3.456, P = 0.006) or 500 mL (OR: 6.199, 95% CI: 2.108-18.228, P = 0.001) in the ICU patients. CONCLUSIONS FI occurs frequently in early ICU days, especially in patients receiving MV and CRRT. However, further investigation of a consensus definition of FI and risk factors is still warranted in future studies.

Abstract
PURPOSE OF REVIEW Hydration and nutritional support is a vital part of medical care, thus a clear understanding of the optimal approach is vital for medical professionals. This is a particularly pertinent issue for patients admitted to a critical care setting. This article aims to define the advantages and disadvantages of gastric and postpyloric feeding in the critical care setting, thus aiding decision-making for clinicians. RECENT FINDINGS Within the article, the main themes covered are those relating to enteral feeding tube placement, the impact of enteral feeding route on ventilator-associated pneumonia, optimization of enteral tube feeding in critical care and the impact that a chosen route may have upon gastrointestinal function. SUMMARY The value of enteral feeding in critical illness is proven beyond doubt and the simplest approach has long been 'if the gut works, use it'. If gastric feeding is not able to be established or is not tolerated then jejunal feeding should be considered as a preferable alternative to parenteral nutrition. Improving access to service or techniques for postpyloric tube placement would assist in optimizing nutritional support in the critical care setting.

Abstract
The preferential use of the oral/enteral route in critically ill patients over gut rest is uniformly recommended and applied. This article provides practical guidance on enteral nutrition in compliance with recent American and European guidelines. Low-dose enteral nutrition can be safely started within 48 h after admission, even during treatment with small or moderate doses of vasopressor agents. A percutaneous access should be used when enteral nutrition is anticipated for ≥ 4 weeks. Energy delivery should not be calculated to match energy expenditure before day 4–7, and the use of energy-dense formulas can be restricted to cases of inability to tolerate full-volume isocaloric enteral nutrition or to patients who require fluid restriction. Low-dose protein (max 0.8 g/kg/day) can be provided during the early phase of critical illness, while a protein target of > 1.2 g/kg/day could be considered during the rehabilitation phase. The occurrence of refeeding syndrome should be assessed by daily measurement of plasma phosphate, and a phosphate drop of 30% should be managed by reduction of enteral feeding rate and high-dose thiamine. Vomiting and increased gastric residual volume may indicate gastric intolerance, while sudden abdominal pain, distension, gastrointestinal paralysis, or rising abdominal pressure may indicate lower gastrointestinal intolerance.

Abstract
BACKGROUND The main goal of enteral nutrition (EN) is to manage malnutrition in order to improve clinical outcomes. However, EN may increase the risks of vomiting or aspiration pneumonia during gastrointestinal dysfunction. Consequently, monitoring of gastric residual volume (GRV), that is, to measure GRV periodically and modulate the speed of enteral feeding according to GRV, has been recommended as a management goal in many intensive care units. Yet, there is a lack of robust evidence that GRV monitoring reduces the level of complications during EN. The best protocol of GRV monitoring is currently unknown, and thus the precise efficacy and safety profiles of GRV monitoring remain to be ascertained. OBJECTIVES To investigate the efficacy and safety of GRV monitoring during EN. SEARCH METHODS We searched electronic databases including CENTRAL, MEDLINE, Embase, and CINAHL for relevant studies on 3 May 2021. We also checked reference lists of included studies for additional information and contacted experts in the field. SELECTION CRITERIA We included randomized controlled trials (RCTs), randomized cross-over trials, and cluster-RCTs investigating the effects of GRV monitoring during EN. We imposed no restrictions on the language of publication. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results for eligible studies and extracted trial-level information from each included study, including methodology and design, characteristics of study participants, interventions, and outcome measures. We assessed risk of bias for each study using Cochrane's risk of bias tool. We followed guidance from the GRADE framework to assess the overall certainty of evidence across outcomes. We used a random-effects analytical model to perform quantitative synthesis of the evidence. We calculated risk ratios (RRs) with 95% confidence intervals (CIs) for dichotomous and mean difference (MD) with 95% CIs for continuous outcomes. MAIN RESULTS We included eight studies involving 1585 participants. All studies were RCTs conducted in ICU settings. Two studies (417 participants) compared less-frequent (less than eight hours) monitoring of GRV against a regimen of more-frequent (eight hours or greater) monitoring. The evidence is very uncertain about the effect of frequent monitoring of GRV on mortality rate (RR 0.91, 95% CI 0.60 to 1.37; I² = 8%; very low-certainty evidence), incidence of pneumonia (RR 1.08, 95% CI 0.64 to 1.83; heterogeneity not applicable; very low-certainty evidence), length of hospital stay (MD 2.00 days, 95% CI -2.15 to 6.15; heterogeneity not applicable; very low-certainty evidence), and incidence of vomiting (RR 0.14, 95% CI 0.02 to 1.09; heterogeneity not applicable; very low-certainty evidence). Two studies (500 participants) compared no GRV monitoring with frequent (12 hours or less) monitoring. Similarly, the evidence is very uncertain about the effect of no monitoring of GRV on mortality rate (RR 0.87, 95% CI 0.62 to 1.23; I² = 51%; very low-certainty evidence), incidence of pneumonia (RR 0.70, 95% CI 0.43 to 1.13; heterogeneity not applicable; very low-certainty evidence), length of hospital stay (MD -1.53 days, 95% CI -4.47 to 1.40; I² = 0%; very low-certainty evidence), and incidence of vomiting (RR 1.47, 95% CI 1.13 to 1.93; I² = 0%; very low-certainty evidence). One study (322 participants) assessed the impact of GRV threshold (500 mL per six hours) on clinical outcomes. The evidence is very uncertain about the effect of the threshold for GRV at time of aspiration on mortality rate (RR 1.01, 95% CI 0.74 to 1.38; heterogeneity not applicable; very low-certainty evidence), incidence of pneumonia (RR 1.03, 95% CI 0.72 to 1.46; heterogeneity not applicable; very low-certainty evidence), and length of hospital stay (MD -0.90 days, 95% CI -2.60 to 4.40; heterogeneity not applicable; very low-certainty evidence). Two studies (140 participants) explored the effects of returning or discarding the aspirated/drained GRV. The evidence is uncertain about the effect of discarding or returning the aspirated/drained GRV on the incidence of vomiting (RR 1.00, 95% CI 0.06 to 15.63; heterogeneity not applicable; very low-certainty evidence) and volume aspirated from the stomach (MD -7.30 mL, 95% CI -26.67 to 12.06, I² = 0%; very low-certainty evidence) We found no studies comparing the effects of protocol-based EN strategies that included GRV-related criteria against strategies that did not include such criteria. AUTHORS' CONCLUSIONS The evidence is very uncertain about the effect of GRV on clinical outcomes including mortality, pneumonia, vomiting, and length of hospital stay.

Abstract
ABSTRACT Gastric tube feeding is a common and valuable intervention for patients in a variety of care settings. While tube feeding can save the lives of patients for whom oral feeding isn't possible, intolerance to tube feeding is a potential complication. This article discusses risk factors for feeding intolerance; the assessment of signs and symptoms of feeding intolerance; the various means of assessing gastric emptying, including the practice of monitoring gastric residual volume (GRV); the controversy surrounding GRV monitoring in assessing feeding tolerance; and the special considerations for monitoring feeding tolerance in acutely and critically ill adults with coronavirus disease 2019. The author, a nurse researcher with extensive experience in the area of enteral feeding, briefly summarizes recommendations and guidelines for enteral feeding published by national and international health care organizations between 2015 and 2020, and offers her perspective on best nursing practices for monitoring food tolerance in adults.

Abstract
BACKGROUND & AIMS Different metabolic phases can be distinguished in critical illness, which influences nutritional treatment. Achieving optimal nutritional treatment during these phases in critically ill patients is challenging. COVID-19 patients seem particularly difficult to feed due to gastrointestinal problems. Our aim was to describe measured resting energy expenditure (mREE) and feeding practices and tolerance during the acute and late phases of critical illness in COVID-19 patients. METHODS Observational study including critically ill mechanically ventilated adult COVID-19 patients. Indirect calorimetry (Q-NRG+, Cosmed) was used to determine mREE during the acute (day 0-7) and late phase (>day 7) of critical illness. Data on nutritional intake, feeding tolerance and urinary nitrogen loss were collected simultaneously. A paired sample t-test was performed for mREE in both phases. RESULTS We enrolled 21 patients with a median age of 59 years [44-66], 67% male and median BMI of 31.5 kg/m2 [25.7-37.8]. Patients were predominantly fed with EN in both phases. No significant difference in mREE was observed between phases (p = 0.529). Sixty-five percent of the patients were hypermetabolic in both phases. Median delivery of energy as percentage of mREE was higher in the late phase (94%) compared to the acute phase (70%) (p = 0.001). Urinary nitrogen losses were significant higher in the late phase (p = 0.003). CONCLUSION In both the acute and late phase, the majority of the patients were hypermetabolic and fed enterally. In the acute phase patients were fed hypocaloric whereas in the late phase this was almost normocaloric, conform ESPEN guidelines. No significant difference in mREE was observed between phases. Hypermetabolism in both phases in conjunction with an increasing loss of urinary nitrogen may indicate that COVID-19 patients remain in a prolonged acute, catabolic phase.

Abstract
This study aimed to evaluate the relationship between ultrasonographic gastric antral measurements and aspirated gastric residual volume (GRV) in mechanically ventilated critically ill patients receiving enteral nutrition (EN). This prospective observational study included 56 enterally-fed critically ill patients in one-year period. All imaging procedures were done at 30-degree head-of-bed elevation and supine position on epigastric region of abdomen with 2.5-6 MHz convex-array probe just before routine GRV aspiration. The antral cross-sectional area (CSA) was calculated by measuring the anteroposterior (dAP) and craniocaudal diameters (dCC) of the gastric antrum. Total 283 ultrasonographic gastric antrum imaging procedures were done. In only eight (2.82%) attempts, the antrum could not be visualized due to inhibition from intra-gastric air or gas in the surrounding intestinal lumen. The calculated mean antral CSA was 568.15 ± 348.37 mm2 (103.43-2,846.30). The antral CSA correlated significantly with aspirated GRV, and the antral CSA increased linearly with increasing aspirated GRV (R2 = 0.73, p < 0.0001). In Receiver operating characteristic (ROC) analysis of antral CSA ≥ 920 mm2 (mean + 1*SD) for estimating aspirated GRV, the area under the curve (AUC) was 0.848 (95% CI, 0.76 ~ 0.93) (p < 0.0001), and ROC analysis of antral CSA to discriminate aspirated GRV ≥ 250 mL showed a significant relation (AUC = 0.969, 95% CI 0.94 ~ 0.99, p < 0.0001). Ultrasonographic measurement of gastric antral CSA is an easy and reliable bedside procedure to estimate GRV in critically ill patients receiving EN in 30-degree head-of-bed elevation and supine position. Trial registration number: NCT04413474, date of registration: June 17, 2020, retrospectively registered.

Abstract
BACKGROUND Routine checking of gastric residual volumes (GRVs) during enteral feeding within surgical trauma intensive care units (STICUs) is a common practice. However, data on the necessity of this practice and its impact on nutrient delivery are limited. We aim to study the association between the replacement of a routine GRV (rGRV) policy with a triggered GRV (tGRV) policy and the safe achievement of daily nutrition goals. METHODS We prospectively collected data on patients after we instituted a tGRV policy and compared them with a historical cohort of patients who had rGRV assessments in our STICU at a level 1 trauma center. The primary end point was achieving 80% of prescribed nutrient goals. Secondary end points included aspiration pneumonia, witnessed emesis, and glycemic control. RESULTS A total of 145 patients accounting for 1405 STICU days were treated under the tGRV policy, and 156 patients accounting for 1694 STICU days were treated under the rGRV policy. There were no statistically significant differences between the tGRV and rGRV groups with regard to the proportion of days meeting or exceeding protein (56.7% vs 56.2%) or calorie (56.4% vs 56.0%) goals. After adjusting for in-hospital deaths, injury severity score, complications, and STICU time, the predictive margins for meeting caloric and protein goals were higher among the tGRV patients (57% vs 56%), but these differences were not statistically significant. CONCLUSION A tGRV policy did not change protein or calorie delivery among patients or increase the risk of emesis compared with traditional monitoring methods.

Abstract
OBJECTIVE We aimed to investigate practices of nasogastric tube (NGT) intubation and feeding for adults by clinical nurses in China. METHODS A self-designed and validated questionnaire comprising 30 questions was distributed to 560 clinical nurses in three comprehensive hospitals of Xiamen, China. The questionnaire covered participants' demographic characteristics, NGT placement, administration of enteral nutrition (EN), and monitoring or management of feeding intolerance. RESULTS A total 464 (82.9%) questionnaires were completed; 36.2% of nurses used nose-ear-xiphoid and 79.5% forehead-xiphoid measurement to define the internal length of the NGT. Many participants still used traditional methods to confirm NGT placement (auscultation of injected air 50.2%, bubble test 34.7% and observing feeding tube aspirate 34.3%). Bolus feeding was the most commonly used technique to administer EN. A total 97.0% of all nurses used syringes to measure gastric residual volume (GRV), and 62.7% measured GRV every 4-8 hours. The most frequently used GRV threshold values were 200 mL (44.6%) and 150 mL (25.2%). Most nurses stopped feeding immediately when encountering high GRV (84.3%) or diarrhea (45.0%). The nasogastric feeding practices of many clinical nurses were not consistent with international guidelines. CONCLUSIONS Our study can provide an impetus for nursing administrators to revise their nasogastric feeding procedures, to promote compliance with evidence-based guidelines.

Abstract
On August 13-14, 2019, the Healthcare Nutrition Council and the ASN held the Medical Foods Workshop: Science, Regulation, and Practical Aspects. Medical food products help patients manage their disease and improve their quality of life. Yet many hurdles exist to getting patients new products. In this workshop, participants addressed some of these hurdles, with specific emphasis on topics like the statutory term distinctive nutritional requirements, the regulatory term modification of the diet alone, the role of clinical guidelines, the requirement that medical foods be used under medical supervision, and differentiation of foods for special dietary use from medical foods, as well as product innovation and future research. Real-world examples were discussed for intractable epilepsy, diabetes, end-stage renal disease, and inflammatory bowel disease.

Abstract
The general physical examination of a patient is an axiom of critical care medicine, but evidence to support this practice remains sparse. Given the lack of evidence for a comprehensive physical examination of the entire patient on admission to the intensive care unit, which most clinicians consider an essential part of care, should clinicians continue the practice of a specialized gastrointestinal system physical examination when commencing enteral nutrition in critically ill patients? In this review of literature related to gastrointestinal system examination in critically ill patients, the focus is on gastrointestinal sounds and abdominal distension. There is a summary of what these physical features represent, an evaluation of the evidence regarding use of these physical features in patients after abdominal surgery, exploration of the rationale for and against using the physical findings in routine practice, and detail regarding what is known about each feature in critically ill patients. Based on the available evidence, it is recommended that an isolated symptom, sign, or bedside test does not provide meaningful information. However, it is submitted that a comprehensive physical assessment of the gastrointestinal system still has a role when initiating or administering enteral nutrition: specifically, when multiple features are present, clinicians should consider further investigation or intervention.

Abstract
Sufficient energy and essential nutrients are vital for normal growth and development in childhood. Ideally, nutrition should be provided orally. However, if the gastrointestinal system is functional, enteral tube feeding can be used when nutritional requirements cannot be provided orally, thus providing nutritional benefits and enabling positive disease management in pediatric patients. Postoperative care in children allows monitoring of the position and functionality of the tube; performing nutrition intolerance, growth, hydration, and nutritional assessments; and performing metabolic and complication follow-ups. Tube feeding in pediatric patients is beneficial and has positive effects in controlling and managing diseases and providing appropriate nutrition in children. However, in postoperative patients, it is important to prevent potential complications, which can be classified into 5 groups: mechanical, gastrointestinal, metabolic, infectious, and pulmonary complications. Important points for managing complications include having enteral nutrition practices based on evidence-based guidelines, sharing outcomes with nurses working in clinical settings, creating enteral feeding guides in clinical settings, providing patients/patients' family with training in line with these guides, and maintaining follow-ups at home. This literature review discusses complications and practices regarding the management of complications after percutaneous endoscopic gastrostomy.

Abstract
IMPORTANCE Evaluating prefeed gastric residuals is considered routine care but has little supporting evidence. OBJECTIVE To determine the effect of omitting prefeed gastric residual evaluation on nutritional outcomes in extremely preterm infants. DESIGN, SETTING, AND PARTICIPANTS This single-center randomized clinical trial compared the omission of gastric residual evaluation with prefeed gastric residual evaluation. Infants were recruited from a level 4 neonatal intensive care unit and were enrolled from October 17, 2013, to October 8, 2016, and then followed up for 6 weeks after birth. Eligible participants were infants born at 32 or fewer weeks' gestation with a birth weight of 1250 g or less; they were enrolled within 72 hours after birth and within 24 hours after feeding initiation. All participants (N = 143) were included in the modified intent-to-treat analysis, which was conducted from March to July 2018. INTERVENTIONS The residual group underwent prefeed gastric residual evaluation; the no residual group did not. Feeding decisions were made according to nutritional guidelines, and infants received only human milk. MAIN OUTCOMES AND MEASURES The primary outcome was weekly enteral nutrition intake in mL/kg for 6 weeks after birth. RESULTS Of 143 infants, 74 (51.7%) were randomized to undergo gastric residual evaluation (residual group) and 69 (48.3%) to omitted gastric residual evaluation (no residual group). The residual group comprised an even number of male and female infants (37 [50.0%]) with a mean (SD) gestational age of 27.1 (2.4) weeks and a mean (SD) birth weight of 888.8 (206.6) grams, whereas the no residual group had more male infants (36 [52.17%]), a mean (SD) gestational age of 27 (1.2) weeks, and a mean (SD) birth weight of 915.2 (180) grams. The no residual group had feedings that advanced more quickly compared with the residual group (mean weekly increase, 20.7 mL/kg/d vs 17.9 mL/kg/d; P = .02) and consumed more feedings at weeks 5 (137.2 [95% CI, 128.6-145.8]; P = .03) and 6 (141.6 [95% CI, 133.2-150.0]; P = .03). Among the secondary outcomes, the no residual group had higher mean estimated log weights (7.01 [95% CI, 6.99-7.02] vs 6.98 [95% CI, 6.97-7.00]; P = .03), had fewer episodes of abdominal distention (0.59 [95% CI, 0.34-1.01] vs 1.79 [95% CI, 1.27-2.53]; P = .001), and were discharged 8 days earlier (4.21 [95% CI, 4.14-4.28] vs 4.28 [95% CI, 4.19-4.36]; P = .01). Odds for necrotizing enterocolitis (0.058 [95% CI, 0.018-0.190] vs 0.026 [95% CI, 0.006-0.109]), death (0.004 [95% CI, 0.0003-0.046] vs 0.012 [95% CI, 0.001-0.131]), late-onset sepsis (0.970 [95% CI, 0.67-1.40] vs 1.38 [95% CI, 0.97-1.94]), and ventilator-associated pneumonia (0.084 [95% CI, 0.033-0.214] vs 0.056 [95% CI, 0.019-0.168]) were similar between groups. CONCLUSIONS AND RELEVANCE Among extremely preterm infants, the omission of gastric residual evaluation increased the delivery of enteral nutrition as well as improved weight gain and led to earlier hospital discharge; these results may translate into evidence-based practice.

Abstract
BACKGROUND Monitoring gastric residual volume has been a common practice in intensive care patients receiving enteral feeding worldwide. Recent studies though, have challenged the reliability and necessity of this routine monitoring process. Several studies even reported improvements in the delivery of enteral feeding without monitoring gastric residual volume, while incurring no additional adverse events. However, the benefit of monitoring gastric residual volume remains controversial in intensive care patients. OBJECTIVE The aim of this review is to identify the effects of not monitoring gastric residual volume in intensive care patients through a meta-analysis of the data pooled from published studies that meet our inclusion criteria. DESIGN A systematic review DATA SOURCES: An electronic search of Embase, Pubmed, and the Cochrane Library was completed up to April 2018. The data included basic population characteristics, related complications, mortality, duration of mechanical ventilation and intensive care unit length of stay. REVIEW METHODS Eligibility and methodological quality of the studies were assessed by two researchers independently according to the Joanna Briggs Institute guidelines. The Review Manager Software was used to calculate the pooled risk ratio (RR), weighted mean difference, and the corresponding 95% confidential interval (95% CI). Sensitivity analyses were done by excluding each study. Publication bias analyses were conducted to avoid the exaggerated effect of the overall estimates. RESULTS Five studies involving 998 patients were included in this meta-analysis. Compared with monitoring gastric residual volume, not monitoring gastric residual volume decreased the rate of feeding intolerance in critically ill patients (RR = 0.61, 95%CI 0.51-0.72), and did not result in an increment in the rate of mortality (RR = 0.97, 95%CI 0.73-1.29, P = 0.84) or the rate of ventilator-associated pneumonia (RR = 1.03, 95%CI 0.74-1.44, P = 0.85). There were also no differences in the duration of mechanical ventilation (MD = 0.09, 95%CI, -0.99 to 1.16, P = 0.88) or intensive care unit length of stay (MD=-0.18, 95%CI, -1.52 to 1.17, P = 0.79). CONCLUSION Except for an increased risk of vomiting, the absence of monitoring gastric residual volume was not inferior to routine gastric residual volume monitoring in terms of feeding intolerance development, mortality, and ventilator-associated pneumonia in intensive care patients. There is encouraging evidence that not measuring gastric residual volume does not induce additional harm to the patients. More multicenter, randomized clinical trials are required to verify these findings.

Abstract
BACKGROUND Malnutrition increases the risk of mortality and morbidity in the pediatric intensive care unit (PICU). Barriers to adequate delivery of enteral nutrition (EN) include hemodynamic instability, feeding interruptions and intolerance, and lack of standardized feeding protocols. The most recent guidelines on nutrition support for the critically ill child describe a paucity of evidence around the best method to deliver EN. There is an untested clinical assumption that bolus gastric feeding (B-GF) in intubated patients is associated with aspiration events, lung injury, and associated morbidity compared with continuous gastric feeding (C-GF). This study compared the effectiveness and safety of C-GF vs B-GF in intubated pediatric patients. METHODS We enrolled randomized patients aged 1 month-12 years who were intubated within 24 hours and received EN starting within 48 hours of admission to a C-GF or B-GF group. Goal-directed EN volume and caloric density were increased every 3 and 12 hours, respectively, to target. Feeding interruptions and intolerance events were recorded. RESULTS Twenty-five subjects were enrolled (B-GF = 11; C-GF = 14). At 24 hours, B-GF was associated with higher energy and protein delivery (P < 0.007) and was associated with faster time to goal volume (median B-GF = 15 hours; C-GF = 29.5 hours). No aspiration events resulting in additional lung injury were noted for either group (P = 0.866). CONCLUSIONS B-GF was associated with superior delivery of EN with a comparable safety profile to C-GF. Further study is needed to compare both EN methods in other PICU populations.

Abstract
OBJECTIVE To analyze the differences in nurses' clinical practice for assessing residual gastric volume and identifying the theoretical framework which supports their practice. METHOD A cross-sectional study carried out by sending an online questionnaire by e-mail to nurses registered at the Regional Nursing Council of the State of São Paulo. RESULTS This study included 598 nursing professionals, with 484 only providing care to adults and 114 exclusively to children. The gastric residual volume test is performed by 83.4% of nursing professionals; in most cases the suspension and prescription of enteral nutritional therapy are performed by the physician. Suspension of enteral nutritional therapy among adults predominantly occurs when the gastric residual volume is equal to 200 ml, and in children when values are less than 100 ml. Procedure after diet suspension involves the return of aspirated gastric contents and maintaining the catheter closed until the next hour in 48.3% of the procedures among adults, and 68.4% among children. 42.9% of the participants in this study were not aware of the theoretical basis that supports the test performance. CONCLUSION We can highlight the need for nurses' training and further studies focused on the practice for assessing gastric residual volume.

Ozen N, Blot S, Ozen V, Arikan Donmez A, Gurun P, Cinar FI, Labeau S. Gastric residual volume measurement in the intensive care unit: an international survey reporting nursing practice. Nurs Crit Care 2018; 23:263-269. [PMID: 30039544 DOI: 10.1111/nicc.12378] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Revised: 06/17/2018] [Accepted: 06/20/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND Gastric residual volume measurement is routinely used to evaluate the feeding tolerance and gastro-oesophageal reflux in patients receiving enteral feeding therapy in the intensive care unit. However, little supportive evidence for this intervention is available as the usefulness of gastric residual volume measurements in patients receiving enteral feeding therapy in the intensive care is controversial. AIM The aim of this study was to assess the practice of intensive care unit nurses related to gastric residual volume measurement in patients receiving enteral nutrition. METHODS A survey was conducted among a sample of intensive care unit nurses (n = 832) from four hospitals in Turkey (n = 182) and attendees of the Annual Congress of the Flemish Society for Critical Care Nurses in Flanders, Belgium (n = 650). The survey instrument was developed by the researchers based on the related literature. RESULTS A total of 480 nurses completed the questionnaire (response rate = 73%). Gastric residual volume is measured by 98·0% of respondents, with wide variations in the frequency of measuring. A 50-200 mL gastric residual volume is considered problematic by 45·5% (n = 183) of the participants, and only 18·4% (n = 81) reported their practice to be based on a current guideline. Strikingly, more experienced intensive care unit nurses appear to perform gastric residual volume measurements more commonly than their less experienced colleagues (p = 0·004), while the practice is more often reported to be performed in Belgium than in Turkey (p < 0·001). CONCLUSION Gastric residual volume management could be improved by applying current evidence to daily nursing practice. RELEVANCE TO CLINICAL PRACTICE Our results show that increased awareness of these guidelines by nurses is needed to reduce inefficient use of working time and resources, streamline clinical practices and improve patient outcomes. Current gastric residual volume measurement guidelines and up-to-date, relevant training should be provided to nurses.

[PMID: 29914737 DOI: 10.1016/j.burns.2018.05.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Revised: 03/22/2018] [Accepted: 05/17/2018] [Indexed: 12/17/2022]
Abstract
PURPOSE Measuring gastric residual volumes (GRV) is common in intensive care units (ICU) in patients receiving enteral nutrition (EN) and are a common source of feeding interruptions. Interruptions in EN yield adverse outcomes and are an area of improvement in burn care. The objectives of this study are to summarize the literature's ICU GRV practices and offer practical suggestions to GRV management in the burn patient. METHODS PubMed, SCOPUS, and OvidSP Medline were systematically reviewed using the keywords: burns; thermal injury; gastric residual volume; enteral feeding; tube feeding; enteral nutrition; gastric intolerance; ICU; critical illness. Reviews, case reports, and consensus and opinion papers were excluded. RESULTS 26 articles were identified. Six burn-specific studies were identified. GRV practices vary widely and are a common cause of EN interruption. Elevated GRVs do not equate to gastrointestinal intolerance and do not always reflect aspiration risk. CONCLUSIONS We advocate a GRV threshold of 500mL should be used to optimize the benefits of EN in burn ICUs. A single incident of elevated GRVs should not mandate immediate EN rate reduction or cessation but should prompt a thoughtful examination of secondary causes of gastrointestinal intolerance. Randomized controlled trials are needed to define the ideal GRV threshold and re-evaluate its role in burn care.

Abstract
BACKGROUND & AIMS Guidance on managing the nutritional requirements of critically ill patients in the intensive care unit (ICU) has been issued by several international bodies. While these guidelines are consulted in ICUs across the Asia-Pacific and Middle East regions, there is little guidance available that is tailored to the unique healthcare environments and demographics across these regions. Furthermore, the lack of consistent data from randomized controlled clinical trials, reliance on expert consensus, and differing recommendations in international guidelines necessitate further expert guidance on regional best practice when providing nutrition therapy for critically ill patients in ICUs in Asia-Pacific and the Middle East. METHODS The Asia-Pacific and Middle East Working Group on Nutrition in the ICU has identified major areas of uncertainty in clinical practice for healthcare professionals providing nutrition therapy in Asia-Pacific and the Middle East and developed a series of consensus statements to guide nutrition therapy in the ICU in these regions. RESULTS Accordingly, consensus statements have been provided on nutrition risk assessment and parenteral and enteral feeding strategies in the ICU, monitoring adequacy of, and tolerance to, nutrition in the ICU and institutional processes for nutrition therapy in the ICU. Furthermore, the Working Group has noted areas requiring additional research, including the most appropriate use of hypocaloric feeding in the ICU. CONCLUSIONS The objective of the Working Group in formulating these statements is to guide healthcare professionals in practicing appropriate clinical nutrition in the ICU, with a focus on improving quality of care, which will translate into improved patient outcomes.

Abstract
In critical care, malnutrition has a significant, negative impact on a patient's ability to respond to medical treatment. Enteral nutrition is known to counteract the metabolic changes associated with critical illness that increase the risk for serious complications and poor clinical outcomes. Inadequate delivery of nutrition support and underfeeding persist in intensive care units despite the availability of guidelines and current research for best practice. Recent studies have shown that nutrition support protocols are effective in promoting nutritional goals in a wide variety of intensive care patients. It is essential to find approaches that enhance early delivery of enteral nutrition that meets requirements and supports improved outcomes. Nurses are in a unique position to take an active role in promoting the best nutritional outcomes for their patients by using and evaluating nutrition support protocols.

Abstract
The objective of this study was to determine the difference between gastric residual volume measurements without giving air compared to giving 30 ml of air via the feeding tube. This experimental study was on 60 subjects fed enterally at a university hospital. Data collection was with the 12-item "Gastric Residual Volume Measurement Instructions" and "Gastric Residual Volume Observation Form." The same subjects composed experimental and control groups. Gastric residual volume measurements were taken before feedings at 10:00 a.m., 1:00 p.m., and 4:00 p.m. with a 60-ml syringe. First measurement was taken without giving air by withdrawing the syringe piston at 2-3 ml/second. Second measurement was applied by giving 30 ml of air and withdrawing the piston at the same speed. Student's t test was used for data analysis. A total of 180 measurements were made for each method. Gastric residual volume averages were 3.71 ± 7.97 ml without air and 3.78 ± 8.08 ml with air. The difference between averages was statistically significant (p < .05). Difficulties withdrawing the syringe piston without giving air occurred in 85% of the intermittently enterally fed patients and 22.8% of those fed continuously. Gastric residual volume measurements with air were higher than those without air. The aspiration procedure with air was easier. Gastric residual volume measurements should be made with 30 ml of air and by withdrawing the syringe piston at 2-3 ml/minute.

Abstract
BACKGROUND Enteral tube feed (ETF) intolerance occurs frequently in hospitalized patients and more so in critically ill patients. Most critical care nurses continue to assess gastric residual volume (GRV), especially among those with a history of ETF intolerance. We hypothesized that ultrasound assessment of GRV correlates directly with aspirated tube feed volume. METHODS This was a prospective cohort study of a convenience sample of critically ill mechanically ventilated patients admitted to an intensive care unit receiving ETF. The gastric antrum was imaged using the aorta and inferior vena cava (IVC) as landmarks concurrently and simultaneously using a curvilinear probe in the midline. All ultrasound measurements were performed at 30 degrees head up, in the supine position, and prior to the assessment of GRV by nursing staff blinding the ultrasonographer to gastric volume aspirated. Gastric antral area was determined by assessing anteroposterior (AP) and craniocaudal (CC) diameters of the gastric antrum. RESULTS Gastric cross-sectional area (CSA) using IVC as a landmark ( R2 = 0.92, P < .0001) and aorta as a landmark ( R2 = 0.86, P < .0001) correlated with aspirated volume. CC diameter of the stomach measured using the aorta as a landmark correlated with aspirated volume and increased linearly with increasing GRV ( R2 = 0.78, P < .0001). A CC diameter of <10 cm using the aorta as a landmark predicted a gastric volume of <500 mL. CONCLUSIONS Ultrasound assessment provides accurate assessment of gastric volume in real-life settings, and the CC diameter of the gastric antrum provides a simple surrogate of GRV.

Abstract
PURPOSE This study aimed to evaluate the effects of not measuring gastric residual volume (GRV) in intensive care patients on a mechanical ventilator and receiving enteral feeding on the feeding intolerance, gastroesophageal reflux (GER) risk, and nutritional adequacy. METHODS This randomized clinical study was performed in 2 medical intensive care units of 2 university hospitals in Ankara, Turkey. The patients were randomized into 2 groups. In the group with GRV monitoring, GRV was measured 3 times a day, and the GRV threshold was accepted as 250 mL. In addition, 24-hour pH monitoring was used in this group to assess the risk of GER. In the group without GRV monitoring, GRV was not measured. The patients were followed-up for 5 days. RESULTS The feeding targets were reached more quickly in the group without GRV monitoring (n = 26) with no increase in the complication rate (P < .05). No significant relationship was found between GRV and GER in the group with GRV monitoring (n = 25) (P > .05). CONCLUSION The discrepancies in GRV measurement make it unreliable for monitoring feeding intolerance and GER. The use of GRV measurements may therefore be discontinued as part of the standard care protocol in medical intensive care units.

Abstract
Appropriate nutrition is an essential component of intensive care management of children with acute respiratory distress syndrome (ARDS) and is linked to patient outcomes. One out of every two children in the pediatric intensive care unit (PICU) will develop malnutrition or have worsening of baseline malnutrition and present with specific micronutrient deficiencies. Early and adequate enteral nutrition (EN) is associated with improved 60-day survival after pediatric critical illness, and, yet, despite early EN guidelines, critically ill children receive on average only 55% of goal calories by PICU day 10. Inadequate delivery of EN is due to perceived feeding intolerance, reluctance to enterally feed children with hemodynamic instability, and fluid restriction. Underlying each of these factors is large practice variation between providers and across institutions for initiation, advancement, and maintenance of EN. Strategies to improve early initiation and advancement and to maintain delivery of EN are needed to improve morbidity and mortality from pediatric ARDS. Both, over and underfeeding, prolong duration of mechanical ventilation in children and worsen other organ function such that precise calorie goals are needed. The gut is thought to act as a "motor" of organ dysfunction, and emerging data regarding the role of intestinal barrier functions and the intestinal microbiome on organ dysfunction and outcomes of critical illness present exciting opportunities to improve patient outcomes. Nutrition should be considered a primary rather than supportive therapy for pediatric ARDS. Precise nutritional therapies, which are titrated and targeted to preservation of intestinal barrier function, prevention of intestinal dysbiosis, preservation of lean body mass, and blunting of the systemic inflammatory response, offer great potential for improving outcomes of pediatric ARDS. In this review, we examine the current evidence regarding dose, route, and timing of nutrition, current recommendations for provision of nutrition to children with ARDS, and the current literature for immune-modulating diets for pediatric ARDS. We will examine emerging data regarding the role of the intestinal microbiome in modulating the response to critical illness.

Abstract
Early enteral nutrition (EN) is consistently recommended as first-line nutrition therapy in critically ill patients since it favorably alters outcome, providing both nutrition and nonnutrition benefits. However, critically ill patients receiving mechanical ventilation are at risk for regurgitation, pulmonary aspiration, and eventually ventilator-associated pneumonia (VAP). EN may increase these risks when gastrointestinal (GI) dysfunction is present. Gastric residual volume (GRV) is considered a surrogate parameter of GI dysfunction during the progression of enteral feeding in the early phase of critical illness and beyond. By monitoring GRV, clinicians may detect patients with delayed gastric emptying earlier and intervene with strategies that minimize or prevent VAP as one of the major risks of EN. The value of periodic GRV measurements with regard to risk reduction of VAP incidence has frequently been questioned in the past years. Increasing the GRV threshold before interrupting gastric feeding results in marginal increases in EN delivery. More recently, a large randomized clinical trial revealed that abandoning GRV monitoring did not negatively affect clinical outcomes (including VAP) in mechanically ventilated patients. The results have revived the discussion on the role of GRV monitoring in critically ill, mechanically ventilated patients receiving early EN. This review summarizes the most recent clinical evidence on the use of GRV monitoring in critically ill patients. Based on the clinical evidence, it discusses the pros and cons and further addresses whether GRV is a dead marker or still alive for the nutrition management of critically ill patients.

Abstract
Microaspiration of subglottic secretions through channels formed by folds in high volume-low pressure poly-vinyl chloride cuffs of endotracheal tubes is considered a significant pathogenic mechanism of ventilator-associated pneumonia (VAP). Therefore a series of prevention measures target the avoidance of microaspiration. However, although some of these can minimize microaspiration, benefits in terms of VAP prevention are not always obvious. Polyurethane-cuffed endotracheal tubes successfully reduce microaspiration but high quality data demonstrating VAP rate reduction are lacking. An analogous conclusion can be made regarding taper-shaped cuffs compared with classic barrel-shaped cuffs. More clinical data regarding these endotracheal tube designs are needed to demonstrate clinical value in addition to in vitro-based evidence. The clinical usefulness of endotracheal tubes developed for subglottic secretions drainage is established in multiple studies and confirmed by meta-analysis. Any change in cuff design will fail to prevent microaspiration if the cuff is insufficiently inflated. At least one well-designed trial demonstrated that continuous cuff pressure monitoring and control decrease the risk of VAP. Gel lubrication of the cuff prior to intubation temporarily hampers microaspiration through sludging the channels formed by folds in high volume-low pressure cuffs. As the beneficial effect of gel lubrication is temporarily, its potential to reduce VAP risk is probably nonsignificant. A minimum positive end-expiratory pressure of at least 5 cmH2O can be recommended as it reduces the risk of microaspiration in vitro and in vivo. One randomized controlled study demonstrated a reduced risk of VAP in patients ventilated with PEEP (5–8 cmH2O). Regarding head-of-bed elevation, it can be recommended to avoid supine positioning. Whether a 45° head-of-bed elevation is to be preferred above 25-30° head-of-bed elevation remains unproven. Finally, the routine monitoring of gastric residual volumes in mechanically ventilated patients receiving enteral nutrition cannot be recommended.

Abstract
AIM To describe a practice change initiative that improved the provision of enteral nutrition (EN) to patients in a New Zealand tertiary intensive care unit (ICU). METHODS The project reviewed and summarized EN literature, amended local policy, and an evidence-based EN delivery algorithm was developed. The EN practice change initiative was implemented and evaluated. Data was collected and analyzed in a pre-audit (2009) and a post-audit (2013). RESULTS Comparison of the pre-audit (N = 25) and the post-audit (N = 40) data demonstrated improvements in three areas of EN delivery. The commencement of early EN within 24 h of admission was evident for a large proportion of patients in both 2009 and 2013 audits. There was a large reduction in time between the two audits for both ICU admission to achievement of EN goal rate (M = 57·71 h versus M = 33·79 h, p = 0·006) and also for EN commencement to achievement of EN goal rate (M = 31·65 h versus M = 10·15 h, p = 0·000). The volume of prescribed EN delivered on days 2, 4 and 6 was greater in the 2013 audit in comparison to the 2009 audit. Staff compliance with adhering to the EN policy and algorithm improved from 46% in 2009, to 95% in 2013. CONCLUSIONS The practice change has significantly improved the practice delivery of EN for patients in the local ICU resulting in optimal care. RELEVANCE TO CLINICAL PRACTICE Malnutrition is highly prevalent among intensive care patients. Strategies and initiatives that improve the delivery of enteral nutrition to the critical care population is therefore vitally important. This article describing such an initiative is thus highly relevant to all health care professionals delivering enteral nutrition in intensive and critical care units.

Abstract
It is increasingly recognized that the nutrition of critically ill patients is a highly complex activity with many unanswered questions. Much research has been performed showing that early enteral nutrition helps to avoid complications. In addition, it has already been shown that the calorie goal as the sole diet goal rather plays a minor role, if one pays attention to sufficient supply of proteins. The diet of the different patient groups with their very individual physiological conditions and their very different diseases are another difficile question in nutritional therapy. The question about the best access path currently appears clearly to be the way of enteral nutrition. Although there seems to be no clear advantage to the gastric or jejunal route, the gastric tube is apparently used more often in clinical practice due to the ease of placement. Reflux control is also currently controversially discussed. To assess the intestinal transport capacity, control of reflux is inevitable, but the amount of reflux that should be considered as cut-off criteria is still unclear. The field of immunonutrition or the substitution of selenium, glutamine, and other substances requires further research. The goal of this article is to provide the reader with a review of the current literature concerning nutritional needs of intensive care patients.

Abstract
The intensive care unit is a work environment where superior dedication is pivotal to optimize patients' outcomes. As this demanding commitment is multidisciplinary in nature, it requires special qualities of health care workers and organizations. Thus research in the field covers a broad spectrum of activities necessary to deliver cutting-edge care. However, given the abundance of research articles and education activities available, it is difficult for modern critical care clinicians to keep up with the latest progress and innovations in the field. This article broadly summarizes new developments in multidisciplinary intensive care, providing elementary information about advanced insights in the field by briefly describing selected articles bundled in specific topics. Issues considered include cardiovascular care, monitoring, mechanical ventilation, infection and sepsis, nutrition, education, patient safety, pain assessment and control, delirium, mental health, ethics, and outcomes research.

Abstract
Critically ill patients are at high risk of malnutrition and lean body mass loss. Screening for malnutrition and performing detailed assessment of energy needs should be routine for patients admitted to intensive care units. Providing adequate calorie and protein provisions can attenuate muscle loss in many at-risk patients. Enteral nutrition is associated with decreased risks of morbidity and infections and is therefore preferred to parenteral nutrition in hemodynamically stable patients with favorable anatomy. Judicious use of steroids and paralytics in combination with adequate glucose control may decrease the risk of developing critical illness polyneuromyopathy. There is growing evidence for the potential immune-enhancing benefits of many micronutrients and vitamins in the critically ill, but more research is needed to determine which nutrients are most effective in which disease processes and what dosing regimens are safe and effective. Elderly, obese, and very young patients pose unique challenges for nutrition therapy and early mobility programs. Pairing early mobility programs with optimal nutrition therapy can help reduce morbidity, limit muscle loss, and speed recovery in intensive care unit patients.

Abstract
Nutrition and hydration are vital components of critical care nursing. However, meeting the nutrition and hydration needs of the critically ill older adult is often complex, because of preexisting risk factors (malnutrition, unintentional weight loss, frailty, and dehydration); as well as intensive care unit-related challenges (catabolism, eating and feeding, end-of-life care). This article highlights the challenges of managing nutrition and hydration in the critically ill older adult, reviews assessment principles, and offers strategies for optimizing nutrition and hydration.

Nutrition 2013; 29:1075-9.

Abstract
OBJECTIVE In critically ill patients, the optimal procedure to monitor upper gastrointestinal function is controversial. Several authors have proposed gastric residual volume (GRV) as a tool to guide enteral nutrition. The aim of this contribution is to briefly discuss corresponding studies. METHODS We electronically searched MEDLINE, EMBASE, and CINAHL for studies relevant to the subject. RESULTS Six randomized controlled trials (RCTs) and six prospective observational studies were identified. Each analyzed different thresholds of GRV to guide enteral nutrition and to avoid complications (e.g., vomiting, aspiration, nosocomial pneumonia) in artificially ventilated patients. Due to heterogeneity in outcome measures, patient populations, type and diameter of feeding tubes, and randomization procedures, combination of the results of the six RCTs into a meta-analysis was not appropriate. High-quality RCTs studying medical patients could not demonstrate an association between complication rate and the magnitude of GRV. The only observational study that adjusted results to potential confounders and that studied surgical patients found, however, that the frequency of aspiration increased significantly if a GRV > 200 mL was registered more than once. CONCLUSION For mechanically ventilated patients with a medical diagnosis at admission to the intensive care unit, monitoring of GRV appears unnecessary to guide nutrition. Surgical patients might profit, however, from a low GRV threshold (200 mL).

Abstract
BACKGROUND Although most critically ill patients experience at least 1 blind insertion of a feeding tube during their stay in an intensive care unit, little is known about the types of health care personnel who perform these insertions or about methods used to determine proper positioning of the tubes. OBJECTIVES To describe results from a national survey of critical care nurses about feeding tube practices in their adult intensive care units. The questions asked included who performs blind insertions of feeding tubes and what methods are used to determine if the tubes are properly positioned. METHODS Data were collected from members of the American Association of Critical-Care Nurses via pencil-and-paper and online surveys. Results from both forms were combined for data analysis and were compared with practice recommendations of national-level organizations. RESULTS A total of 2298 responses were obtained. Physicians perform more blind insertions of styleted feeding tubes than do nurses; in contrast, nurses place more nonstyleted tubes. Radiographic confirmation of correct position is mandated more often for blindly inserted styleted tubes (92.3%) than for nonstyleted tubes (57.5%). The 3 most commonly used bedside methods to determine tube location are auscultation for air injected via the tube, appearance of feeding tube aspirate, and observation for indications of respiratory distress. CONCLUSIONS Recommendations from multiple national-level organizations to obtain radiographic confirmation that each blindly inserted feeding tube is correctly positioned before the first use of the tube are not adequately implemented. Auscultation is widely used despite recommendations to the contrary.
