This guideline replaces the previous WoSPGHaN guideline. It aligns to current NHSGGC adult NG guidance and care plan where possible and takes into consideration actions and learning points from recent SAER and Datix.
Objectives
The purpose of this document is to provide guidance to all health care professionals working in acute paediatrics (excluding Neonates) within NHS Greater Glasgow and Clyde (NHSGGC) to provide safe care and delivery of enteral nutrition (EN) through a nasogastric (NG) tube in children and young people.
Adopting a consistent approach will promote a seamless service for children and young people and aims to reduce the potential risks associated with nasogastric tube feeding.
AIM
- To provide information on nasogastric tube feeding that reflects current thinking and evidence based practice to healthcare professionals
- To outline best practice for procedures relating to nasogastric tube feeding
- To promote a consistent approach to nasogastric tube feeding for children/young people
- To promote safe delivery and reduce the potential risks nasogastric tube feeding in children/young people
Scope
This guidance applies to all health care practitioners that care for children and young people with a nasogastric tube within NHSGCC paediatrics. This includes healthcare support workers, registered nurses, medical staff and associated students in undergraduate programmes on placement, bank and agency staff.
Glossary
Introduction
Nasogastric tube feeding is a way to deliver nutrition, hydration and medication into the Gastrointestinal (GI) tract through an artificial flexible tube that is inserted into the stomach through the nasal passage. It is the most suitable route for patients requiring short term enteral feeding support or for patients awaiting procedures to provide longer term access such as a gastrostomy tube. This method of feeding is only necessary or desirable when a patient’s nutritional needs cannot be met orally for various reasons.
This may include, but not limited to;
- Unable to feed by mouth (orally)
- The need for supplemental nutrition or hydration
- Distress during feeding or oral aversion
- Recurrent aspiration
- Decompression and drainage of stomach contents
- Chronic illness
- Acute illness
- Unconscious patient
Indications
Nasogastric feeding can provide effective support in both the short and long terms for patients who cannot meet their nutritional requirement orally and where their gut is still functional. The associated risks and benefits must be assessed and discussed with the patient, their parents/ carers before commencing nasogastric feeding.
- Confirmation and documented by medical staff that this is an appropriate treatment plan
- Is it appropriate to pass a nasogastric tube and commence feeding at this time and is the required equipment available?
- Is there sufficient knowledge or expertise available to test for safe placement of the nasogastric tube?
- Consider referral to Dietetics via Trakcare for assessment, continuing recommendations and monitoring
Roles & responsibilities
All healthcare support workers involved in the insertion, testing and administration of nasogastric feeding should be appropriately trained and supervised until considered competent. A practitioner can be described as competent if they have had the necessary training, clinical experience, skills and knowledge to undertake the task safely and without direct supervision.
The table below outlines the specific roles and responsibilities for healthcare practitioners
|
Senior Healthcare Support Worker Responsibilities |
Registered Nurse Responsibilities |
NB. Healthcare support workers should not be involved in the administration of medication |
|
Consent
Consent is required before healthcare practitioners undertake any care for a patient. Informed consent must be obtained before any procedure taking place, this involves a clear explanation of the risks and benefits. This may be informal (verbal) or formal (written) for more complex procedures. Children and young people under 16 years old have the legal capacity to consent, or refuse treatment on their own behalf, if they are deemed capable of understanding the nature and possible consequences of treatment. A parent or legal guardian may consent to medical treatment if the child lacks decision-making capacity.
In emergency situation, common law and duty of care reasoning allows healthcare practitioners to use clinical judgment as to whether the risks of delaying a procedure outweighs the need for formal consent. The healthcare practitioner must ensure that it is necessary, reasonable and proportionate.
Description of nasogastric tubes in paediatrics
Short Term
These tubes are typically made from Polyvinylchloride (PVC) and are fully radio-opaque. They can remain in place for between 7-10 days, depending on manufacturer’s recommendations. They should be replaced if required for a longer duration as can become brittle over time.
Long Term
These tubes are made from Polyurethane (PUR), fully radio-opaque and typically have a guidewire to aid the passing of the tube. They can remain in place for 90 days or as long as required, depending on manufacturer’s recommendations provided the tube remains intact with no complications. These tubes remain soft and flexible throughout use.
All nasogastric tubes (short and long term) are single use. These should be discarded and replaced with a new tube should it become dislodged.
Selecting size of nasogastric tubes for feeding
The size of the nasogastric tube will vary with the size of the child and the purpose of insertion. If the purpose is for feeding, a smaller size tube is appropriate. This table provides recommended nasogastric tube sizing, however clinical judgement must be used for each individual patient, with consideration for type of milk and/or addition of thickeners for example Carobel, in this instance a larger size nasogastric tube may be more appropriate.
| Age of child/ young person | Size of nasogastric tube |
| Term Newborn / Baby (Birth to 1 year) | 5 or 6fr |
| Infant/ Toddler/ Pre-schooler (1-4 years) | 6 or 8fr |
| School age (5-12 years) | 8fr |
| Young person (13-16 years) | 8 or 10fr |
If the purpose of the tube is decompression or drainage, a larger size tube should be used.
Orogastric Tubes
Orogastric tubes should only be passed after careful consideration and on the advice of a senior clinician.
Orogastric tubes are used scarcely in acute paediatrics. Older infants and children have the potential to bite through any tube sited through this route or displace it through tongue movement, therefore orogastric tubes are primarily used in newborn babies within the Neonatal Intensive Care Unit (NICU) or within the Paediatric Intensive Care Unit (PICU) for patients who are unable to have a nasogastric tube due to clinical presentation.
The insertion procedure is the same as for insertion of nasogastric tube, except the tube is passed directly through the mouth. The length of the tube should be adjusted accordingly (measure from the corner of the mouth, to the earlobe, to the xiphisternum). This tube should be secured to the chin with hypoallergenic tape. All other aspects of care in relation to these tubes are the same as for nasogastric tubes, including pH testing checks for confirmation of position.
Please see local guidance for further information on Orogastric tubes.
Potential contraindications
There are several contraindications to be considered prior to insertion of a nasogastric tube. Seek advice from senior medical staff if a nasogastric tube is to be inserted or the patient is considered at risk.
These may include but not limited to:
- A competent patient refuses treatment
- Basal skull fracture
- Maxilla facial disorders
- Unstable c-spine injuries
- Nasal/ pharyngeal oesophageal obstruction
- Oesophageal Atresia before repair
- Having undergone oesophageal surgery
- Actively bleeding oesophageal or gastric varices
- Clotting disorders
Potential complications
Potential complications which may arise during and after the insertion procedure can include:
|
COMMON COMPLICATIONS |
RARE / SIGNIFICANT COMPLICATIONS |
|
Nasal trauma |
Aspiration |
|
Tube displacement |
Bronchial placement |
|
Tube blockage |
Pleural space placement |
|
Rhinitis / Pharyngitis |
Intra cranial insertion |
|
|
Gastro-oesophageal junction placement of the tip |
|
|
Precipitation of variceal bleeding |
|
|
Strangulation from feeding tubing |
|
|
Perforation of the pharynx, oesophagus or stomach |
Reducing the risk of strangulation from enteral feeding lines
All staff must be aware of strangulation risk with enteral feeding lines, the highest risk being overnight (NPSA 2011). Minimise the risk by observing the following steps:
- Reduce the length of tubing in the cot/ bed
- Remove any unnecessary tubing
- Position feeding pump at head of the cot/ bed with feeding set through the bars and not over the top
- Secure tubing through clothing if possible
- Equipment and tubing should be assessed at regular intervals overnight
- Feeding regimes should be reviewed regularly, especially at the stage where movement overnight is likely to change
If continuous overnight feeding is required, this must be clearly documented in the medical notes.
Troubleshooting
|
PROBLEM |
IMMEDIATE ACTION |
PREVENTION |
|
Aspirate pH >5.5 on pH indicator strip |
Check if the patient is taking acid-inhibiting medication. Follow steps on Decision Tree for Confirming Placement of Nasogastric Tubes for Feeding. |
Create a plan for future testing with the multidisciplinary team. |
|
Nasogastric tube blockage |
Attempt to flush with warm water, using a push/ pull method. Do not use excessive pressure when flushing. If tube cannot be unblocked consider replacing nasogastric tube. |
Ensure nasogastric tube is flushed at regular intervals during a continuous feed and when not in use. It is essential that nasogastric tubes are flushed pre and post feeds and on administration of medications. Use liquid medications where able. |
|
Potential nasogastric tube displacement |
Remove tube and replace if it is still required. |
Ensure nasogastric tube is secured close to the nostril to avoid accidental removal. Administer medications to control vomiting if needed. |
|
Skin irritation and breakdown |
Keep skin and nostrils clear by cleaning regularly. Be aware of potential allergies.
|
Ensure alternate nostrils are used each time the tube is replaced. Apply hydrocolloid dressing underneath nasogastric tube to prevent further breakdown. Consider referral to tissue viability. |
Nursing Management of Nasogastric Feeding Tube
Whilst a nasogastric tube is in place, it is important to keep the skin healthy and prevent skin breakdown. This includes the skin underneath the tapes that hold the tube in place.
- Normal face washing should be undertaken, avoiding moisturiser where tapes are to be applied
- Regularly clean the nostrils to keep them clear, nares should be inspected for skin irritation or breakdown
- Change position of tube exit site ensuring tape not pulling too tightly
- Replace the tapes when they become soiled or appear to be peeling off, checking skin condition below the tape and changing location of tape where possible
- When removing the tapes, always use medical adhesive remover to help prevent Medical Adhesive Related Skin Injury (MARSI)
Mouth Care
Children who are nasogastric tube fed may be taking little or no food and drink by mouth. Despite this regular brushing of teeth is essential to ensure cleanliness, prevent plaque build-up and provide comfort.
If there is a risk of aspiration, poor oral hygiene poses a risk of harmful bacteria being aspirated, potentially leading to respiratory difficulties or chest infection.
A smear of toothpaste is recommended to be used for children under 3 years and a pea-sized amount for children 3 years and over. Toothpaste containing 1000ppm – 1500ppm fluoride should be used twice per day (Childsmile, 2025), a low foaming toothpaste is recommended if the patient is nil by mouth or unable to spit out the toothpaste. Oral suctioning may be required to remove excess foam/ debris from the mouth.
It is important to provide mouth hydration at regular intervals. Keeping the lips and mouth moist can improve comfort.
Nasal Tube Retaining Device (NTRD) / Nasal Bridal
A Nasal Tube Retaining Device (NTRD)/ Nasal Bridal is a specialized piece of equipment that secures the nasogastric feeding tube and reduces the risk of inadvertent displacement. The NTRD/ Bridal will not completely prevent nasogastric tube displacement, therefore pH testing checks must still be made prior to use for confirmation of position of nasogastric tube.
The NTRD/ Bridal and skin at nose should be assessed at least once daily and documented in the Nasal Tube Retaining Device (NTRD) Care Plan.
For further information and support, refer to local guidance.
Feed Hygiene
Feed hygiene is essential to prevent infection. Food preparation areas and equipment are cleaned at every use. Enteral feeds (breast milk, infant formula or premade enteral nutrition) and equipment must be handled aseptically.
Preparation of enteral feeds:
- Collect all equipment and appropriate feed
- Perform hand hygiene and don appropriate PPE
- Clean and prepare area for aseptic procedure
- Before opening, clean bottle top and shoulders with 70% alcohol 2% chlorhexidine wipe
| PREPACKED ENTERAL NUTRITION |
|
| MATERNAL/ DONOR EXPRESSED BREAST MILK (MEBM/DEBM) |
|
| INFANT FORMULA |
|
Once feeding has commenced, feed containers must not be ‘topped up’ with sterile feed, including Prepacked Enteral Nutrition, DEBM/ MEBM or Infant Formula.
Enteral Feeding Equipment
All healthcare workers should demonstrate knowledge and competency relative to the Flocare enteral feeding pump and are responsible for monitoring the patient throughout use.
Administration sets used must be compatible with the Flocare device and changed every 24 hours.
If there is any concern about damage, contamination or safety, the set should be discarded.
Only syringes labelled ‘enteral’ (purple in colour) should be used with enteral feeding systems.
Further information and support with Flocare infusion device can be found at Nutricia Flocare - Infinity 3 Pump
Initiating Nasogastric Tube Feeding
Patients commencing nasogastric tube feeding may require referral to Dietetics for assessment, recommendations and monitoring. Referral should be made via TrakCare. If the patient has not previously been on enteral nutrition and nasogastric tube feeding is to be commenced out of hours, within acute wards initiating nasogastric tube feeding out of hours plan should be followed. Where nasogastric tube feeding is to be commenced within the Paediatric Intensive Care Unit (PICU), further guidance can be found within the Nutrition Resource Book.
If nasogastric tube feeding is considered for the purposes of feeding support during acute bronchiolitis, recommended feed volumes can be found within the Bronchiolitis guideline, RHC, please note these patients are not required to have a Dietetic referral.
Administration of Medications via Nasogastric Feeding Tube
The majority of medicines are suitable to administer via nasogastric tube, provided that clinical judgement and considerations outlined in the guideline are given to each medicine.
When prescribing and administering medicines via nasogastric tubes, a medicine licensed for enteral tubes should be explored in the first instance to ensure safety and efficacy. Manipulating medicines (i.e. crushing/ dispersing or opening capsules) are rarely covered by the medicines license, as they are not intended to be used in this manner, and are therefore used ‘off-label’. ‘Off-label’ administration can be necessary in paediatric practice when there is no suitable alternative.
Consider the increased risk or issues that may be associated with using a medicine ‘off-label’:
- Risk of blockage [table 1]. Do not assume that liquid formulation will be suitable, or that tablet and liquid formulations are clinically interchangeable.
- Risk of drug loss in the enteral tubing. A few medicines may adsorb onto the tube material, reducing their bioavailability [table 2].
- A medicine’s absorption and efficacy may be influenced by feeds [table 3].
- Crushing gastro-resistant ‘GR’ or modified-release tablets ‘MR’ ‘SR’ or ‘XL’ changes the way the medicine is delivered in the body. The crushed coating can also risk blocking tubes.
- Some liquid formulations have high sorbitol content, which can lead to osmotic diarrhoea and cramping (>140mg/kg/day). These medicines should be diluted with water to reduce their osmolality.
- Effervescent formulations can lead to sediment or gas build up in the enteral tubing if not properly dispersed before administration.
When administering medicines via nasogastric tube ensure protective equipment is worn when crushing tablets. Particular care should be taken to avoid exposure to medicines that are cytotoxic, immunosuppressive, antimicrobial, or hormonal. If you are unsure, check with pharmacy.
Paediatric patients that are established on continuous feeds have additional considerations when administering medicines via nasogastric tubes, particularly for medicines whose absorption and efficacy may be influenced by feeds [table 3]. If the medicine is available in an alternative formulation, consider switching and monitor response. If not, make the ward pharmacist and managing dietitian aware to see if the feed plan can be modified.
Discharge Planning
Prior to discharge careful consideration should be given to ensure patients can be discharged home safely on nasogastric tube feeding. This includes identifying who will be responsible for daily care of tube, set up of the feed and relevant training for patient/ carer should be provided.
The Nasogastric Feeding Support and Training Pack for Parents and Carers is available from clinical areas or ordered from Medical Illustration, this must be completed prior to discharge and competency confirmed by a competent Registered Nurse.
Appendix 1: Procedure for Inserting a Nasogastric Tube
Statement
Nasogastric tubes should only be inserted where a patient’s nutritional needs cannot be met orally due to various reasons, and in conjunction with an agreed care plan.
