Abstract
Providing adequate and balanced nutrition for preterm infants, especially extremely/very preterm infants, is the material basis for promoting their normal growth and development and improving long-term prognosis. Enteral nutrition is the best way to feed preterm infants. Previous systematic reviews have shown that using evidence-based standardized feeding management strategies can effectively promote the establishment of full enteral feeding, reduce the duration of parenteral nutrition, improve the nutritional outcomes of preterm infants, and not increase the risk of necrotizing enterocolitis or death. Based on relevant research in China and overseas, the consensus working group has developed 20 recommendations in 5 aspects including the goal of enteral nutrition, transitioning to enteral nutrition, stable growth period enteral nutrition, supplementation of special nutrients, and monitoring of enteral nutrition for preterm infants, using the Grading of Recommendations Assessment, Development and Evaluation. The aim is to provide recommendations for healthcare professionals involved in the management of enteral nutrition for preterm infants, in order to improve the clinical outcomes of preterm infants.

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. [PMID: 38760751 PMCID: PMC11100149 DOI: 10.1186/s12912-024-01994-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Accepted: 05/06/2024] [Indexed: 05/19/2024] Open
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 There are many controversies over the necessity of monitoring gastric residual volume in the nursing care of enteral nutrition. We aimed to conduct an updated meta-analysis to evaluate the effects of monitoring or not monitoring gastric residual volume on patients' outcomes and complications. METHODS We searched the Cochrane Library database to 15 April 2021 for randomized controlled trials (RCTs) on the effects of gastric residual volume and no gastric residual volume monitoring. Review Manager software was used for data analysis. RESULTS A total of seven RCTs involving 1240 enteral nutrition patients were included. Gastric residual volume monitoring was associated with reduced incidence of vomiting (OR2.33, 95% CI:1.68-3.24), whereas no gastric residual volume monitoring was associated with reduced incidence of unnecessary interruptions of enteral nutrition (OR0.38,95% CI:0.26-0.55). There were no significant differences on the incidence of abdominal distention (OR1.87, 95% CI:0.82-4.28), diarrhoea (OR1.03,95% CI:0.74-1.43), VAP (OR0.83, 95%CI:0.37-1.89), duration of mechanical ventilation (MD -0.06,95% CI:-1.22-1.10), length of ICU stay (MD -1.33, 95% CI:-3.58-0.91) and mortality (OR0.90,95% CI:0.61-1.34). CONCLUSIONS Not monitoring gastric residual volume is associated with reduced unnecessary interruptions of enteral nutrition related to inadequate feeding and increased risk of vomiting.

Abstract
BACKGROUND Routine monitoring of gastric residuals in preterm infants on tube feeds is a common practice in neonatal intensive care units used to guide initiation and advancement of enteral feeding. There is a paucity of consensus on whether to re-feed or discard the aspirated gastric residuals. While re-feeding gastric residuals may aid in digestion and promote gastrointestinal motility and maturation by replacing partially digested milk, gastrointestinal enzymes, hormones, and trophic substances, abnormal residuals may result in vomiting, necrotising enterocolitis, or sepsis. OBJECTIVES To assess the efficacy and safety of re-feeding when compared to discarding gastric residuals in preterm infants. SEARCH METHODS: Searches were conducted in February 2022 in Cochrane CENTRAL via CRS, Ovid MEDLINE and Embase, and CINAHL. We also searched clinical trial databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-RCTs. SELECTION CRITERIA We selected RCTs that compared re-feeding versus discarding gastric residuals in preterm infants. DATA COLLECTION AND ANALYSIS Review authors assessed trial eligibility and risk of bias and extracted data, in duplicate. We analysed treatment effects in individual trials and reported the risk ratio (RR) for dichotomous data and the mean difference (MD) for continuous data, with respective 95% confidence intervals (CIs). We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We found one eligible trial that included 72 preterm infants. The trial was unmasked but was otherwise of good methodological quality. Re-feeding gastric residual may have little or no effect on time to regain birth weight (MD 0.40 days, 95% CI -2.89 to 3.69; 59 infants; low-certainty evidence), risk of necrotising enterocolitis stage ≥ 2 or spontaneous intestinal perforation (RR 0.71, 95% CI 0.25 to 2.04; 72 infants; low-certainty evidence), all-cause mortality before hospital discharge (RR 0.50, 95% CI 0.14 to 1.85; 72 infants; low-certainty evidence), time to establish enteral feeds ≥ 120 mL/kg/d (MD -1.30 days, 95% CI -2.93 to 0.33; 59 infants; low-certainty evidence), number of total parenteral nutrition days (MD -0.30 days, 95% CI -2.07 to 1.47; 59 infants; low-certainty evidence), and risk of extrauterine growth restriction at discharge (RR 1.29, 95% CI 0.38 to 4.34; 59 infants; low-certainty evidence). We are uncertain as to the effect of re-feeding gastric residual on number of episodes of feed interruption lasting for ≥ 12 hours (RR 0.80, 95% CI 0.42 to 1.52; 59 infants; very low-certainty evidence). AUTHORS' CONCLUSIONS We found only limited data from one small unmasked trial on the efficacy and safety of re-feeding gastric residuals in preterm infants. Low-certainty evidence suggests re-feeding gastric residual may have little or no effect on important clinical outcomes such as necrotising enterocolitis, all-cause mortality before hospital discharge, time to establish enteral feeds, number of total parenteral nutrition days, and in-hospital weight gain. A large RCT is needed to assess the efficacy and safety of re-feeding of gastric residuals in preterm infants with adequate certainty of evidence to inform policy and practice.

Abstract
BACKGROUND Routine monitoring of gastric residual in preterm infants on gavage feeds is a common practice used to guide initiation and advancement of feeds. It is believed that an increase in or an altered gastric residual may be predictive of necrotising enterocolitis (NEC). Withholding monitoring of gastric residual may take away the early indicator and thus may increase the risk of NEC. However, routine monitoring of gastric residual as a guide, in the absence of uniform standards, may lead to unnecessary delay in initiation and advancement of feeds and hence might result in a delay in establishing full enteral feeds. This in turn may increase the duration of total parenteral nutrition (TPN) and central venous line usage, increasing the risk of associated complications. Furthermore, delays in establishing full enteral feeds increase the risk of extrauterine growth restriction and neurodevelopmental impairment. OBJECTIVES • To assess the efficacy and safety of routine monitoring versus no monitoring of gastric residual in preterm infants • To assess the efficacy and safety of routine monitoring of gastric residual based on two different criteria for interrupting feeds or decreasing feed volume in preterm infants SEARCH METHODS: We conducted searches in Cochrane CENTRAL via CRS, Ovid MEDLINE, Embase and CINAHL in February 2022. We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials (RCTs), quasi- and cluster-RCTs. SELECTION CRITERIA We selected RCTs that compared routine monitoring versus no monitoring of gastric residual and trials that used two different criteria for gastric residual to interrupt feeds in preterm infants. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial eligibility, risk of bias and extracted data. We analysed treatment effects in individual trials and reported risk ratio (RR) for dichotomous data, and mean difference (MD) for continuous data, with respective 95% confidence intervals (CI). We calculated the number needed to treat for an additional beneficial/harmful outcome (NNTB/NNTH) for dichotomous outcomes with significant results. We used GRADE to assess the certainty of evidence. MAIN RESULTS We included five studies (423 infants) in this updated review. Routine monitoring versus no routine monitoring of gastric residual in preterm infants Four RCTs with 336 preterm infants met the inclusion criteria for this comparison. Three studies were performed in infants with birth weight of < 1500 g, while one study included infants with birth weight between 750 g and 2000 g. The trials were unmasked but were otherwise of good methodological quality. Routine monitoring of gastric residual: - probably has little or no effect on the risk of NEC (RR 1.08, 95% CI 0.46 to 2.57; 334 participants, 4 studies; moderate-certainty evidence); - probably increases the time to establish full enteral feeds (MD 3.14 days, 95% CI 1.93 to 4.36; 334 participants, 4 studies; moderate-certainty evidence); - may increase the time to regain birth weight (MD 1.70 days, 95% CI 0.01 to 3.39; 80 participants, 1 study; low-certainty evidence); - may increase the number of infants with feed interruption episodes (RR 2.21, 95% CI 1.53 to 3.20; NNTH 3, 95% CI 2 to 5; 191 participants, 3 studies; low-certainty evidence); - probably increases the number of TPN days (MD 2.57 days, 95% CI 1.20 to 3.95; 334 participants, 4 studies; moderate-certainty evidence); - probably increases the risk of invasive infection (RR 1.50, 95% CI 1.02 to 2.19; NNTH 10, 95% CI 5 to 100; 334 participants, 4 studies; moderate-certainty evidence); - may result in little or no difference in all-cause mortality before hospital discharge (RR 2.14, 95% CI 0.77 to 5.97; 273 participants, 3 studies; low-certainty evidence). Quality and volume of gastric residual compared to quality of gastric residual alone for feed interruption in preterm infants One trial with 87 preterm infants met the inclusion criteria for this comparison. The trial included infants with 1500 g to 2000 g birth weight. Using two different criteria of gastric residual for feed interruption: - may result in little or no difference in the incidence of NEC (RR 5.35, 95% CI 0.26 to 108.27; 87 participants; low-certainty evidence); - may result in little or no difference in time to establish full enteral feeds (MD -0.10 days, 95% CI -0.91 to 0.71; 87 participants; low-certainty evidence); - may result in little or no difference in time to regain birth weight (MD 1.00 days, 95% CI -0.37 to 2.37; 87 participants; low-certainty evidence); - may result in little or no difference in number of TPN days (MD 0.80 days, 95% CI -0.78 to 2.38; 87 participants; low-certainty evidence); - may result in little or no difference in the risk of invasive infection (RR 5.35, 95% CI 0.26 to 108.27; 87 participants; low-certainty evidence); - may result in little or no difference in all-cause mortality before hospital discharge (RR 3.21, 95% CI 0.13 to 76.67; 87 participants; low-certainty evidence). - we are uncertain about the effect of using two different criteria of gastric residual on the risk of feed interruption episodes (RR 3.21, 95% CI 0.13 to 76.67; 87 participants; very low-certainty evidence). AUTHORS' CONCLUSIONS Moderate-certainty evidence suggests routine monitoring of gastric residual has little or no effect on the incidence of NEC. Moderate-certainty evidence suggests monitoring gastric residual probably increases the time to establish full enteral feeds, the number of TPN days and the risk of invasive infection. Low-certainty evidence suggests monitoring gastric residual may increase the time to regain birth weight and the number of feed interruption episodes, and may have little or no effect on all-cause mortality before hospital discharge. Further RCTs are warranted to assess the effect on long-term growth and neurodevelopmental outcomes.

Abstract
OBJECTIVES Routine gastric aspirate (RGA) monitoring is a common yet controversial practice intended for early identification of gastrointestinal pathology in infants receiving gavage feeds. Our objectives were to evaluate the association of ceasing RGA monitoring on the incidence of necrotizing enterocolitis (NEC) as well as nutritional outcomes in a large population of very low birth weight (VLBW) and very preterm neonates. METHODS Retrospective record review of neonates born ≤32 weeks and/or VLBW from 2 cohorts: (1) during pre-feed RGA monitoring (September 2015 to June 2018) and (2) after cessation of RGA ("non-RGA") monitoring (July 2018 to December 2020). We compared incidence of NEC, time-to-full enteral feeds, central line duration, and duration of parenteral nutrition (PN) in bivariate and multivariable models accounting for changes in feeding protocols over time. RESULTS We identified 617 subjects, 53% in the RGA monitoring cohort (n = 327) and 47% in non-RGA cohort (n = 290). The non-RGA cohort had feeds initiated earlier ( P < 0.0001), achieved full enteral feeds more rapidly ( P < 0.0001), received a shorter duration of PN ( P = 0.0003), and had shorter central access duration ( P < 0.0001) without increasing NEC risk. In fact, the non-RGA cohort had a lower incidence of NEC ( P = 0.0345) compared to the RGA cohort. Even after adjusting for changes in feeding protocols over time in a multivariable model, the RGA cohort had significantly higher odds of NEC. CONCLUSIONS Pre-feed RGA monitoring in the absence of concerning clinical exam findings is not indicated for neonates receiving gavage feeds as it does not improve NEC incidence but instead may delay important nutritional outcomes such as feed initiation and central line removal.

Abstract
OBJECTIVES Neonatal sepsis is one of the leading causes of neonatal deaths in neonatal intensive care units. Hence, it is essential to review the evidence from systematic reviews on interventions for reducing late-onset sepsis (LOS) in neonates. METHODS PubMed and the Cochrane Central were searched from inception through August 2020 without any language restriction. Cochrane reviews of randomized clinical trials (RCTs) assessing any intervention in the neonatal period and including one or more RCTs reporting LOS. Two authors independently performed screening, data extraction, assessed the quality of evidence using Cochrane Grading of Recommendations Assessment, Development and Evaluation, and assessed the quality of reviews using a measurement tool to assess of multiple systematic reviews 2 tool. RESULTS A total of 101 high-quality Cochrane reviews involving 612 RCTs and 193,713 neonates, evaluating 141 interventions were included. High-quality evidence showed a reduction in any or culture-proven LOS using antibiotic lock therapy for neonates with central venous catheters (CVC). Moderate-quality evidence showed a decrease in any LOS with antibiotic prophylaxis or vancomycin prophylaxis for neonates with CVC, chlorhexidine for skin or cord care, and kangaroo care for low birth weight babies. Similarly, moderate-quality evidence showed reduced culture-proven LOS with intravenous immunoglobulin prophylaxis for preterm infants and probiotic supplementation for very low birth weight (VLBW) infants. Lastly, moderate-quality evidence showed a reduction in fungal LOS with the use of systemic antifungal prophylaxis in VLBW infants. CONCLUSIONS The overview summarizes the evidence from the Cochrane reviews assessing interventions for reducing LOS in neonates, and can be utilized by clinicians, researchers, policymakers, and consumers for decision-making and translating evidence into clinical practice.

Abstract
OBJECTIVES To investigate whether evidence-based standardized nutrition protocol can facilitate the establishment of full enteral nutrition and its effect on short-term clinical outcomes in very preterm/very low birth weight infants. METHODS A retrospective analysis was performed on the medical data of 312 preterm infants with a gestational age of ≤32 weeks or a birth weight of <1 500 g. The standardized nutrition protocol for preterm infants was implemented in May 2020; 160 infants who were treated from May 1, 2019 to April 30, 2020 were enrolled as the control group, and 152 infants who were treated from June 1, 2020 to May 31, 2021 were enrolled as the test group. The two groups were compared in terms of the time to full enteral feeding, the time to the start of enteral feeding, duration of parenteral nutrition, the time to recovery to birth weight, the duration of central venous catheterization, and the incidence rates of common complications in preterm infants. RESULTS Compared with the control group, the test group had significantly shorter time to full enteral feeding, time to the start of enteral feeding, duration of parenteral nutrition, and duration of central venous catheterization and a significantly lower incidence rate of catheter-related bloodstream infection (P<0.05). There were no significant differences between the two groups in the mortality rate and the incidence rate of common complications in preterm infants including grade II-III necrotizing enterocolitis (P>0.05). CONCLUSIONS Implementation of the standardized nutrition protocol can facilitate the establishment of full enteral feeding, shorten the duration of parenteral nutrition, and reduce catheter-related bloodstream infection in very preterm/very low birth weight infants, without increasing the risk of necrotizing enterocolitis.

Efficacy and safety of Mydriatic Microdrops for Retinopathy Of Prematurity Screening (MyMiROPS): study protocol for a non-inferiority crossover randomized controlled trial. Trials 2022; 23:322.

Abstract
BACKGROUND Retinopathy of prematurity (ROP) eye examination screening presupposes adequate mydriasis for an informative fundoscopy of preterm infants at risk, on a weekly basis. Systemic absorption of the instilled mydriatic regimens has been associated with various adverse events in this fragile population. This report aims to present the fully developed protocol of a full-scale trial for testing the hypothesis that the reduced mydriatic drop volume achieves adequate mydriasis while minimizing systemic adverse events. METHODS A non-inferiority crossover randomized controlled trial will be performed to study the efficacy and safety of combined phenylephrine 1.67% and tropicamide 0.33% microdrops compared with standard drops in a total of 93 preterm infants requiring ROP screening. Primary outcome will be the pupil diameter at 45 (T45) min after instillation. Pupil diameter at T90 and T120 will constitute secondary efficacy endpoints. Mixed-effects linear regression models will be developed, and the 95% confidence interval approach will be used for assessing non-inferiority. Whole blood samples will be analyzed using hydrophilic liquid chromatography-tandem mass spectrometry method (HILIC-MS/MS), for gathering pharmacokinetic (PK) data on the instilled phenylephrine, at nine specific time points within 3 h from mydriasis. Pooled PK data will be used due to ethical restrictions on having a full PK profile per infant. Heart rate, oxygen saturation, blood pressure measurements, and 48-h adverse events will also be recorded. DISCUSSION This protocol is designed for a study powered to assess non-inferiority of microdrops compared with standard dilating drops. If our hypothesis is confirmed, microdrops may become a useful tool in ROP screening. TRIAL REGISTRATION ClinicalTrials.gov NCT05043077 . Registered on 2 September 2021.

[PMID: 35177107 PMCID: PMC8851703 DOI: 10.1186/s13052-022-01208-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 01/10/2022] [Indexed: 11/21/2022] Open
Abstract
Objective Prefeed gastric residuals (GRs) monitoring has been correlated with an increased time to reach full feeds and longer parenteral nutrition without beneficial effect on necrotizing enterocolitis (NEC) occurrence. We aimed to assess effects of a new local protocol to provide for the selective evaluation of GRs excluding their routine monitoring. Methods We carried out a retrospective study based on a “before and after” design in a cohort of infants born at 23+0–31+6 weeks of gestation. The primary outcome was the age at full enteral feeding (150 mL/kg/d). Secondary outcomes included age at regaining of birth weight, and evaluation of Z-scores of weight, length, and head circumference at discharge. Results We studied 49 infants in the selective GR group and 59 in the routine GR group. Age at full (150 mL/kg) enteral feeding (17.8 ± 10.1 vs. 22.9 ± 10.5 days, P = 0.017) and regaining of birth weight (11.1 ± 3.0 vs. 12.5 ± 3.5 days, P = 0.039) were lower while the Z-scores of weight at discharge (-1.10 ± 0.83 vs. -1.60 ± 1.45, P = 0.040) were higher in infants in the selective GR group in comparison with infants in the routine GR group. Conclusions Selective monitoring of GRs decreased age at full enteral feeding and at regaining of birth weight and induced better Z-scores of weight at discharge in comparison with routine GR monitoring in a cohort of extremely preterm infants without increasing the incidence of NEC. Omitting prefeed GRs monitoring in clinical practice seems reasonable. Supplementary Information The online version contains supplementary material available at 10.1186/s13052-022-01208-7.

Growth of Very Preterm Infants in a Low-Resourced Rural Setting after Affiliation with a Human Milk Bank. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9010080. [PMID: 35053701 PMCID: PMC8774553 DOI: 10.3390/children9010080] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 12/17/2021] [Accepted: 12/28/2021] [Indexed: 11/17/2022]
Abstract
The extrauterine growth restriction (EUGR) of very preterm infants has been associated with long-term complications and neurodevelopmental problems. EUGR has been reported at higher rates in low resource settings. There is limited research investigating how metropolitan human milk banks contribute to the growth outcomes of very preterm infants cared in rural areas. The setting of this study is located at a rural county in Taiwan and affiliated with the Taiwan Southern Human Milk Bank. Donor human milk was provided through a novel supplemental system. A renewal nutritional protocol was initiated as a quality improvement project after the affiliated program. This study aimed to compare the clinical morbidities and growth outcome at term equivalent age (TEA) of preterm infants less than 33 weeks of gestational age before (Epoch-I, July 2015–June 2018, n = 40) and after the new implementation (Epoch-II, July 2018–December 2020, n = 42). The Epoch-II group significantly increased in bodyweight z-score at TEA ((−0.02 ± 1.00) versus Epoch-I group (−0.84 ± 1.08), p = 0.002). In multivariate regression models, the statistical difference between two epochs in bodyweight z-score changes from birth to TEA was still noted. Modern human milk banks may facilitate the nutritional protocol renewal in rural areas and improve the growth outcomes of very preterm infants cared for. Establishing more distribution sites of milk banks should be encouraged.

Abstract
Necrotising enterocolitis (NEC) is a potentially serious illness with significant mortality and morbidity in preterm infants. Previous studies have reported association of volume and colour (bile and blood stained) of gastric residuals (GR) with NEC. We aimed to study this association in our cohort of extremely preterm (EP) infants. In a case-control study using retrospective data (January 2006-December 2011), EP (gestation < 28 weeks) infants with confirmed NEC ≥ stage II (cases) were compared with infants without NEC (controls) matched for birth weight (BW) and gestational age (GA). Forty cases of NEC ≥ stage II diagnosed at a median (IQR) age of 16.5 days (10.3-23) were compared with 40 controls matched for gestation (± 3 days) and birth weight (± 680 g). Median maximum GR volume (GRV) from birth to the day of occurrence of NEC was significantly higher in cases vs. controls (5.9 vs.3.7 ml; p < 0.001). Increased maximum GRV was associated with NEC ≥ Stage II in adjusted analysis (aOR 1.36, 95%CI 1.06-1.75, p = 0.017). There was no significant difference in GRV between cases and controls throughout the clinical course, including 72, 48 and 24 h before the onset of NEC. However, green (65.0% vs. 27.5%, p = 0.001) and haemorrhagic GRs (45.0% vs. 27.5%, p = 0.092) were higher 24 h before the diagnosis of NEC.Conclusion: GRV was not associated with NEC ≥ stage II. However, green and haemorrhagic GRs were significantly higher 24 h before the diagnosis of the illness. Adequately powered prospective studies are needed to confirm the significance of our findings. What is Known: •It is unclear whether large volume, dark-coloured and blood-stained GRs are associated with NEC. •The value of routine monitoring of gastric residuals in preterm infants is currently being questioned. What is New: •Volume of gastric residuals was not associated with significant NEC. •Green and haemorrhagic GRs were significantly higher 24 hours before diagnosis of NEC.

Using a human-centred design approach to develop a comprehensive newborn monitoring chart for inpatient care in Kenya. BMC Health Serv Res 2021; 21:1010. [PMID: 34556098 PMCID: PMC8461871 DOI: 10.1186/s12913-021-07030-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Accepted: 09/09/2021] [Indexed: 01/25/2023] Open
Abstract
Introduction Job aids such as observation charts are commonly used to record inpatient nursing observations. For sick newborns, it is important to provide critical information, intervene, and tailor treatment to improve health outcomes, as countries work towards reducing neonatal mortality. However, inpatient vital sign readings are often poorly documented and little attention has been paid to the process of chart design as a method of improving care quality. Poorly designed charts do not meet user needs leading to increased mental effort, duplication, suboptimal documentation and fragmentation. We provide a detailed account of a process of designing a monitoring chart. Methods We used a Human-Centred Design (HCD) approach to co-design a newborn monitoring chart between March and May 2019 in three workshops attended by 16–21 participants each (nurses and doctors) drawn from 14 hospitals in Kenya. We used personas, user story mapping during the workshops and observed chart completion to identify challenges with current charts and design requirements. Two new charts were piloted in four hospitals between June 2019 and February 2020 and revised in a cyclical manner. Results Challenges were identified regarding the chart design and supply, and how staff used existing charts. Challenges to use included limited staffing, a knowledge deficit among junior staff, poor interprofessional communication, and lack of appropriate and working equipment. We identified a strong preference from participants for one chart to capture vital signs, assessment of the baby, and feed and fluid prescription and monitoring; data that were previously captured on several charts. Discussion Adopting a Human-Centred Design approach, we designed a new comprehensive newborn monitoring chart that is unlike observation charts in the literature that only focus on vital signs. While the new chart does not address all needs, we believe that once implemented, it can help build a clearer picture of the care given to newborns. Conclusion The chart was co-designed and piloted with the user and context in mind resulting in a unique monitoring chart that can be adopted in similar settings.

Routine prefeed gastric aspiration in preterm infants: a systematic review and meta-analysis. Eur J Pediatr 2021; 180:2367-2377. [PMID: 34018044 DOI: 10.1007/s00431-021-04122-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 05/11/2021] [Accepted: 05/13/2021] [Indexed: 01/11/2023]
Abstract
Despite lack of evidence, the practice of routine prefeed gastric residue aspiration before the next feed is common. Recent studies suggest that this practice might be even harmful. Therefore, we aimed to evaluate the effect of avoiding routine prefeed gastric residue aspiration as compared to routine aspiration, on various clinical outcomes in preterm infants. We searched five different electronic databases (MEDLINE, EMBASE, Web of Science, CINAHL, and Cochrane Library) until March 8, 2021. Only randomized controlled trials comparing the practice of routine prefeed gastric aspiration with no routine aspiration in preterm infants were considered eligible. The random-effects meta-analysis was done using RevMan 5.3 software. Of the 894 unique records identified by our search, we included 6 studies (451 participants) in the review. There was no significant difference in the incidence of necrotizing enterocolitis (RR 0.80; 95% CI 0.31 to 2.08; 421 participants in 5 trials). Avoiding routine prefeed aspiration was associated with achieving full enteral feeds earlier (MD - 3.19 days, 95% CI - 4.22 to - 2.16), shorter duration of hospitalization (MD - 5.32 days; 95% CI - 10.25 to - 0.38), and lower incidence of late-onset sepsis (RR 0.77; 95% CI 0.60 to 0.99). Time to regain birth weight, days of total parenteral nutrition or central venous line usage, culture-positive sepsis, and all-cause mortality did not differ between the two groups.Conclusion: In the absence of other signs of feed intolerance, routine prefeed gastric residue aspiration should be avoided in preterm infants.Prospero registration number: CRD42020197657 What is Known: • Though, routine prefeed aspiration before next feed is a common practice in preterm gavage-fed infants. • Recent study suggests that the omission of routine gastric residual evaluation led to improved weight gain and earlier hospital discharge. What is New: • Low- to moderate-quality evidence suggest that avoiding routine prefeed gastric residue monitoring helps in the reduction of late-onset sepsis, achieving full enteral feeds earlier, and earlier discharge from the hospital. • Abandoning the practice of routine prefeed aspiration in absence of other signs of feed intolerance in preterm low birthweight neonates is safe.

Abstract
Providing adequate amounts of all essential macro- and micronutrients to preterm infants during the period of extraordinarily rapid growth from 24 to 34 weeks' postmenstrual age to achieve growth as in utero is challenging yet important, since early growth restriction and suboptimal neonatal nutrition have been identified as risk factors for adverse long-term development. Along with now well-established early parenteral nutrition, this review emphasizes enteral nutrition, which should be started early and rapidly increased. To minimize the side effects of parenteral nutrition and improve outcomes, early full enteral nutrition based on expressed mothers' own milk is an important goal. Although neonatal nutrition has improved in recent decades, existing knowledge about, for example, the optimal composition and duration of parenteral nutrition, practical aspects of the transition to full enteral nutrition or the need for breast milk fortification is limited and intensively discussed. Therefore, further prospective studies on various aspects of preterm infant feeding are needed, especially with regard to the effects on long-term outcomes. This narrative review will summarize currently available and still missing evidence regarding optimal preterm infant nutrition, with emphasis on enteral nutrition and early postnatal growth, and deduce a practical approach.

Abstract
Enteral feeding is the preferred method of nutrient provision for preterm infants. Though parenteral nutrition remains an alternative to provide critical nutrition after preterm delivery, the literature suggests that enteral feeding still confers significant nutritional and non-nutritional benefits. Therefore, the purpose of this narrative review is to summarize health and clinical benefits of early enteral feeding within the first month of life in preterm infants. Likewise, this review also proposes methods to improve enteral delivery in clinical care, including a proposal for decision-making of initiation and advancement of enteral feeding. An extensive literature review assessed enteral studies in preterm infants with subsequent outcomes. The findings support the early initiation and advancement of enteral feeding impact preterm infant health by enhancing micronutrient delivery, promoting intestinal development and maturation, stimulating microbiome development, reducing inflammation, and enhancing brain growth and neurodevelopment. Clinicians must consider these short- and long-term implications when caring for preterm infants.

Abstract
Background: We aimed to evaluate gastric volume changes during intermittent milk feeds (IMF) and continuous milk feeds (CMF) in very premature neonates (VPN), with gastric residual volume (GRV) based on antral cross-sectional area (ACSA) measurements and to examine if there were differences in GRV between the two feeding methods. Methods: A randomized prospective clinical trial with crossover design was conducted in 31 preterm neonates (gestational age < 30 weeks). Gastric volume was assessed twice in each neonate (during IMF and CMF feeding), at 7 specific time points during a 2-h observation period by measuring ACSA changes via the ultrasound (U/S) method. Results: There was a significantly different pattern of gastric volume changes between the two feeding methods. GRV, expressed as the median percentage of ACSA measurement at 120 min relative to the higher ACSA measurement during IMF, was found to be 3% (range 0–25%) for IMF and 50% (range 15–80%) for CMF. Neonates fed with IMF had a shorter mean gastric emptying time compared to those fed with CMF (p = 0.0032). No signs of feeding intolerance were recorded in either group during the period of observation. Conclusions: Our results showed that gastric volume changes and gastric emptying time in VPN, based on ACSA measurement changes, depend on the milk feeding method. No gastrointestinal complications/adverse events were noted with GRV up to 80% with CMF.

Abstract
Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease of neonates, especially of preterm infants, with high morbidity and mortality. The surviving infants may have digestive tract and neurological sequelae. Therefore, the prevention and treatment of NEC are of great significance in improving survival rate and survival quality of neonates. To provide evidence-based recommendations for management of NEC, the guidelines were developed based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and the current domestic and overseas studies.

Abstract
Necrotizing enterocolitis (NEC), the first cause of short bowel syndrome (SBS) in the neonate, is a serious neonatal gastrointestinal disease with an incidence of up to 11% in preterm newborns less than 1500 g of birth weight. The rate of severe NEC requiring surgery remains high, and it is estimated between 20–50%. Newborns who develop SBS need prolonged parenteral nutrition (PN), experience nutrient deficiency, failure to thrive and are at risk of neurodevelopmental impairment. Prevention of NEC is therefore mandatory to avoid SBS and its associated morbidities. In this regard, nutritional practices seem to play a key role in early life. Individualized medical and surgical therapies, as well as intestinal rehabilitation programs, are fundamental in the achievement of enteral autonomy in infants with acquired SBS. In this descriptive review, we describe the most recent evidence on nutritional practices to prevent NEC, the available tools to early detect it, the surgical management to limit bowel resection and the best nutrition to sustain growth and intestinal function.

Antenatal Antibiotic Exposure Affects Enteral Feeding, Body Growth, and Neonatal Infection in Preterm Infants: A Retrospective Study. Front Pediatr 2021; 9:750058.

Abstract
Background: Antibiotics are widely prescribed by obstetricians, which exposes a large number of infants to antenatal antibiotics (AAB). The effect of AAB on various aspects of neonatal development of preterm infants remains unclear. Methods: In this retrospective study, infants born with gestational age (GA) between 22 +0 and 36 +6 weeks at our unit from 2017 to 2019 were included. Multivariable analysis was adopted to examine the associations between AAB exposure and various outcomes related to enteral feeding process, body growth, and neonatal infection after adjusting for potential confounders. Further subanalysis on the exposure level of AAB and stratified analysis by GA (<34 vs. ≥34 weeks) were also conducted. Results: In this cohort comprising 2,543 preterm infants, AAB was associated with decreased risks of feeding intolerance (odds ratio [OR]: 0.63, 95% confidence interval [CI]: 0.48-0.82) and neonatal infection (OR: 0.63, 95% CI: 0.41-0.94). Higher AAB exposure level was associated with higher Z scores of birth weight (β = 0.37, 95% CI: 0.27-0.47), but lower Δbodyweight Z-scores (β = -0.20, 95% CI: -0.27 to -0.13). AAB was positively associated with the parameters related to body growth in infants with GA <34 weeks but negatively associated in those with GA ≥34 weeks. Conclusions: AAB exposure affects the enteral feeding process and neonatal infection. The effects on body growth vary by the exposure level of AAB and GA of infants. A well-designed prospective and preferably multi-centre study with predefined parameters is required to confirm our findings.

Abstract
Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease of neonates, especially of preterm infants, with high morbidity and mortality. The surviving infants may have digestive tract and neurological sequelae. Therefore, the prevention and treatment of NEC are of great significance in improving survival rate and survival quality of neonates. To provide evidence-based recommendations for management of NEC, the guidelines were developed based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and the current domestic and overseas studies.

Abstract
BACKGROUND Immature gut motility in preterm neonates may be a risk factor for necrotizing enterocolitis (NEC). Using preterm pigs as a model for infants, we hypothesized that intestinal dysmotility precedes NEC development. METHODS Eighty-five preterm pigs were fed increasing amounts of milk diets to induce NEC lesions, as detected at autopsy on day 5. Gut transit time was determined on day 4 by x-ray imaging after oral intake of contrast solution. RESULTS No clinical or radiological signs of NEC were detected on day 4, but macroscopic NEC lesions were recorded in 59% of pigs (n = 50) on day 5. Relative to pigs without NEC (noNEC, n = 35), pigs with small intestinal lesions (siNEC, n = 18) showed delayed stomach emptying time (StEmpty) and time for contrast to reach cecum (ToCecum) already on day 4. Pigs with lesions only in colon (coNEC, n = 20) showed more diarrhea, shorter ToCecum time, but longer small intestinal emptying time (SiEmpty). ToCecum time predicted siNEC and coNEC lesions with a receiver-operator characteristic area under the curve of 78-81%. CONCLUSIONS Region-dependent changes in gut transit time is associated with early NEC development in preterm pigs. How gut dysmotility is related to NEC in preterm infants requires further investigations. IMPACT Using preterm pigs as a model for preterm infants, we show that gut transit time, using serial x-ray contrast imaging, was changed in individuals with NEC-like lesions before they showed the typical radiological signs of NEC. Thus prolonged transit time across the entire gut was recorded when NEC lesions appeared in the small intestine but not when lesions were detected only in the colon. Until now, recordings of food transit have mainly investigated changes in the upper gut. Using serial x-rays, this study describes food transit across the entire gut and documents a region-dependent effect of NEC lesions on gut transit changes in preterm individuals. The findings provide proof of concept for use of x-ray contrast imaging as a tool to monitor gut transit in preterm pigs as models for infants. Delayed passage across the entire gut may be an early sign of small intestinal NEC, at least in pigs. More studies are needed to confirm relations in infants. In the future, it might be possible to use x-ray contrast imaging in preterm infants to better understand gut motility in relation to early NEC progression and need for medical NEC treatment.

Mildly Pasteurized Whey Protein Promotes Gut Tolerance in Immature Piglets Compared with Extensively Heated Whey Protein. Nutrients 2020; 12:nu12113391. [PMID: 33158188 PMCID: PMC7694243 DOI: 10.3390/nu12113391] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Revised: 10/28/2020] [Accepted: 11/02/2020] [Indexed: 12/25/2022] Open
Abstract
Human milk is the optimal diet for infant development, but infant milk formula (IMF) must be available as an alternative. To develop high-quality IMF, bovine milk processing is required to ensure microbial safety and to obtain a protein composition that mimics human milk. However, processing can impact the quality of milk proteins, which can influence gastro-intestinal (GI) tolerance by changing digestion, transit time and/or absorption. The aim of this study was to evaluate the impact of structural changes of proteins due to thermal processing on gastro-intestinal tolerance in the immature GI tract. Preterm and near-term piglets received enteral nutrition based on whey protein concentrate (WPC) either mildly pasteurized (MP-WPC) or extensively heated (EH-WPC). Clinical symptoms, transit time and gastric residuals were evaluated. In addition, protein coagulation and protein composition of coagulates formed during in vitro digestion were analyzed in more detail. Characterization of MP-WPC and EH-WPC revealed that mild pasteurization maintained protein nativity and reduced aggregation of β-lactoglobulin and α-lactalbumin, relative to EH-WPC. Mild pasteurization reduced the formation of coagulates during digestion, resulting in reduced gastric residual volume and increased intestinal tract content. In addition, preterm piglets receiving MP-WPC showed reduced mucosal bacterial adherence in the proximal small intestine. Finally, in vitro digestion studies revealed less protein coagulation and lower levels of β-lactoglobulin and α-lactalbumin in the coagulates of MP-WPC compared with EH-WPC. In conclusion, minimal heat treatment of WPC compared with extensive heating promoted GI tolerance in immature piglets, implying that minimal heated WPC could improve the GI tolerance of milk formulas in infants.

Abstract
Green gastric residuals (GR) are often considered as a sign of feed intolerance and discarded in preterm infants. Probiotics are known to enhance feed tolerance in preterm infants. To assess the composition (primary outcome) and volume of discarded green GRs, and feeding outcomes in extremely preterm (EP) infants in a probiotic trial, composition of pale and dark green GRs in the first two weeks of life from EP infants (<28 weeks) in a randomized controlled trial (RCT: SiMPro) of single vs. three-strain probiotics was assessed. Feeding outcomes included time to full feeds (TFF: 150 mL/kg/day) and duration of parenteral nutrition (PN). EP infants given placebo in our previous probiotic RCT served as the reference group. Analysis involved linear regression modelling with clustered standard errors for repeated measurements. GRs of 74/103 from 39 SiMPro infants (18: single-strain, 21: three-strain) were analyzed. Bile acid content was higher but statistically insignificant (825.79 vs. 338.1 µmol/L; p = 0.12) in dark vs. pale green GRs. Mean (95% confidence interval) fat, nitrogen, and carbohydrate loss in GRs over the study period was 0.02 g (0.01–0.03), 0.011 g (0.009–0.013), and 0.05 g (0.04–0.06), respectively. Overall, SiMPro infants had shorter median TFF (10 vs. 14 days, p = 0.02) and duration of PN (10 vs. 16 days, p = 0.022) compared with control group infants. Z scores for growth parameters at discharge were comparable. Discarding dark green GRs meant higher loss of bile acids during early enteral nutrition in EP infants. Probiotic supplementation was associated with reduced TFF and duration of PN.

Abstract
BACKGROUND Routine monitoring of gastric residuals in preterm infants on gavage feeds is a common practice in many neonatal intensive care units and is used to guide the initiation and advancement of feeds. No guidelines or consensus is available on whether to re-feed or discard the aspirated gastric residuals. Although re-feeding gastric residuals may replace partially digested milk, gastrointestinal enzymes, hormones, and trophic substances that aid in digestion and promote gastrointestinal motility and maturation, re-feeding abnormal residuals may result in emesis, necrotising enterocolitis, or sepsis. OBJECTIVES To assess the efficacy and safety of re-feeding compared to discarding gastric residuals in preterm infants. The allocation should have been started in the first week of life and should have been continued at least until the baby reached full enteral feeds. The investigator could have chosen to discard the gastric residual in the re-feeding group, if the gastric residual quality was not satisfactory. However, the criteria for discarding gastric residual should have been predefined.To conduct subgroup analysis based on gestational age (≤ 27 weeks, 28 weeks to 31 weeks, ≥ 32 weeks), birth weight (< 1000 g, 1000 g to 1499 g, ≥ 1500 g), type of milk (human milk or formula milk), quality of the gastric residual (fresh milk, curded milk, or bile-stained gastric residual), volume of gastric residual replaced (total volume, 50% of the volume, volume of the next feed, or prespecified volume, irrespective of the volume of the aspirate, e.g. 2 mL, 3 mL), and whether the volume of gastric residual that is re-fed is included in or excluded from the volume of the next feed (see "Subgroup analysis and investigation of heterogeneity"). SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 1), MEDLINE via PubMed (1966 to 19 February 2018), Embase (1980 to 19 February 2018), and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 19 February 2018). We also searched clinical trial databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA Randomised and quasi-randomised controlled trials that compared re-feeding versus discarding gastric residuals in preterm infants. DATA COLLECTION AND ANALYSIS Two review authors assessed trial eligibility and risk of bias and independently extracted data. We analysed treatment effects in individual trials and reported the risk ratio and risk difference for dichotomous data, and the mean difference for continuous data, with respective 95% confidence intervals. We used the GRADE approach to assess the quality of evidence. MAIN RESULTS We found one eligible trial that included 72 preterm infants. This trial was not blinded.We are uncertain as to the effect of re-feeding gastric residual on efficacy outcomes such as time to regain birth weight (mean difference (MD) 0.40 days, 95% confidence interval (CI) -2.89 to 3.69 days; very low quality evidence), time to reach enteral feeds ≥ 120 mL/kg/d (MD -1.30 days, 95% CI -2.93 to 0.33 days; very low quality evidence), number of infants with extrauterine growth restriction at discharge (risk ratio (RR) 1.29, 95% CI 0.38 to 4.34; very low quality evidence), duration of total parenteral nutrition (MD -0.30 days, 95% CI -2.07 to 1.47 days; very low quality evidence), and length of hospital stay (MD -1.90 days, 95% CI -25.27 to 21.47 days; very low quality evidence).Similarly, we are uncertain as to the effect of re-feeding gastric residual on safety outcomes such as incidence of stage 2 or 3 necrotising enterocolitis and/or spontaneous intestinal perforation (RR 0.71, 95% CI 0.25 to 2.04; very low quality evidence), number of episodes of feed interruption lasting ≥ 12 hours (RR 0.80, 95% CI 0.42 to 1.52; very low quality evidence), or mortality before discharge (RR 0.50, 95% CI 0.14 to 1.85; low-quality evidence). We are uncertain as to the effect of re-feeding gastric residual in the subgroups of human milk-fed and formula-fed infants. We found no data on other outcomes such as linear and head growth during hospital stay, postdischarge growth, number of infants with parenteral nutrition-associated liver disease, and neurodevelopmental outcomes. AUTHORS' CONCLUSIONS We found only limited data from one small unblinded trial on the efficacy and safety of re-feeding gastric residuals in preterm infants. The quality of evidence was low to very low. Hence, available evidence is insufficient to support or refute re-feeding of gastric residuals in preterm infants. A large, randomised controlled trial is needed to provide data of sufficient quality and precision to inform policy and practice.
