Introduction
Chemotherapy induced nausea and vomiting (CINV) is a common and extremely unpleasant side effect for children receiving antineoplastic therapy. CINV can lead to complications of treatment and cause significant emotional and physical distress, disruptions to
            activities of daily living and influence the quality of life of the patient. The goal of antiemetic therapy is to prevent vomiting and minimise nausea before, during and after the administration of chemotherapy. The severity of nausea and vomiting can, to some degree, be predicted by the chemotherapeutic agents being
            delivered but there is a degree of variation between patients. Antiemetic treatments should be initiated prior to the first dose of chemotherapy for best control of nausea and vomiting, as it can often become difficult to control nausea once the child is vomiting. Non-pharmacological measures are also an
            important consideration and should be implemented in conjunction with pharmacological regimens to allow for the effective management of CINV. 
Aim 
The aim of this guideline is to provide an overview of the prevention and management of chemotherapy induced nausea and vomiting in the paediatric oncology patient.

Assessment
 
All patients receiving chemotherapy for childhood cancer or as preconditioning for a haematopoietic stem cell transplant (HSCT) require ongoing assessment of the incidence and severity of nausea and vomiting.          
    
         
    
It is the responsibility of nursing staff to regularly assess patients for signs and symptoms of CINV and decide on subsequent methods of management in consultation with the medical team and pharmacy.           
    
         
    
The following assessment tools can assist in determining the incidence and severity of CINV. Results of the assessment tools should be clearly documented once per shift (more frequently if indicated) in the Electronic Medical Record (EMR). The CINV score (0 to 10) and type of scale
            (BARF or VAS) utilized should be recorded under the Nausea Scale assessment in the Observation flowsheet.

Visual Analogue Scale (VAS)
    
     
    
    
* Baxter Retching Faces Nausea Scale & Visual Analogue Scale- Baxter et al. (2011)  
 
Each of the scales establishes a score from 0 to 10
- A score of 0 indicates no nausea
- A score of 10 indicates worst possible nausea
- The assessment tools should be utilised by health professionals to provide      an overview of the child’s condition which will allow for an appropriate      plan of care based on these findings.
Other
indications of children experiencing CINV may include 
- Food refusal
- Decreased fluid intake
- Decreased urine output
- Retching
- Less interaction with others
- Sweating
Management
and principles of prevention and treatment of chemotherapy induced nausea and
vomiting
Emetic potential of chemotherapy agents    
    
- Chemotherapy agents have different emetic potentials that are classified based on their risk of inducing nausea and vomiting.
Minimal
Emetogenic Potential (Minimal Emetogenic Chemotherapy or MinEC)
- Less than 10% frequency of emesis      in the absence of effective prophylaxis
Low Emetogenic Potential
(Low Emetogenic Chemotherapy or LEC)
- 10 to less than 30% frequency of      emesis in the absence of effective prophylaxis
Moderate
Emetogenic Potential (Moderate Emetogenic Chemotherapy or MEC)
- 30 to 90% frequency of emesis in      the absence of effective prophylaxis
Highly
Emetogenic Potential (Highly Emetogenic Chemotherapy or HEC)
- Greater than 90% frequency of      emesis in the absence of effective prophylaxis 
         
    
Often, combinations of moderately emetogenic agents can yield a course with high emetic potential; for example, both ifosfamide and doxorubicin have moderate emetic potential yet when delivered together have high emetic potential. Other combinations of
            chemotherapy can have low emetic potential but with extra antiemetic cover required at certain times; for example, ALL induction is generally minimal to low emetic potential but antiemetics are usually required around daunorubicin doses or on days when general anaesthetic has been given. The following provides an
            outline of the emetic potential of common chemotherapy agents and regimens;          
    
Guide to the emetic
potential of individual chemotherapy agents
Guide to the
emetic potential of combination chemotherapy regimens         
    
         
    
Antiemetic treatments should be decided based on the emetic potential of the prescribed course of chemotherapy, although there may be some instances where a specific child requires deviations from the guidelines. 
- Deviations from the guidelines should be discussed with the child’s Oncology Fellow/Consultant and Oncology Pharmacy.
- Once an effective antiemetic regimen has been determined for an individual child, this regimen should be used for future courses of chemotherapy as appropriate. 
- Ensure details of a patient’s personalised antiemetic plan are documented by the Oncology Fellow/Consultant in the Antiemetic Plan tool located in the Oncology Activity in the EMR.         
        
 
Pharmacological prevention and management of CINV
The goal of antiemetic therapy is to prevent vomiting and minimise nausea both during and after the administration of chemotherapy. For CINV prophylaxis to be effective;
- Antiemetics should be prescribed and released to the Medication Administration Record (MAR) from the Treatment Plan under the Oncology Activity on EMR
 
- Antiemetics appropriate for the emetogenic class of the chemotherapy agent or regimen, patient’s age and diagnosis should be
 - administered regularly, regardless of nausea or vomiting status (this is to ensure the prevention of breakthrough and delayed CINV)- continued throughout the period of administration of chemotherapy and for at least 24 hours following completion of chemotherapy 
 
 
 
- Ensure antiemetics are ceased 24 to 48 hours following the completion of chemotherapy. Note: agents that cause delayed CINV may require antiemetics for up to 5 days following completion of chemotherapy. If antiemetics are required for longer, please discuss with the oncology fellow/consultant to exclude other causes of nausea and vomiting.
Antiemetic
medications
- The first dose of antiemetics should be given prior to commencing chemotherapy as per the following;
 - Oral – 30 to 60 minutes prior to first dose of chemotherapy (optimal time is 60 minutes prior)
 
- Intravenous – immediately before or up to 30 minutes prior to first dose of chemotherapy (optimal time is 30 minutes prior)

Antiemetic
Guideline 
To ensure effective control of CINV, regular antiemetic therapy should be prescribed and administered according to the emetic potential of the chemotherapy agent or regimen. Recommended medications to be used as antiemetic therapy are outlined in the table below.
Antiemetic steroids should not
be used in patients with brain tumours, AML, CAR T cell therapy or patients
with corticosteroids as part of their chemotherapy regimen.
Halve dose of Dexamethasone if
using Fosaprepitant or Aprepitant.

Breakthrough
CINV  
Breakthrough nausea and vomiting should be treated promptly. It is advised to have further antiemetics charted on the Treatment Plan under the Oncology Activity on EMR to enable nurses to initiate breakthrough medication as required. 
Before prescribing further antiemetics, staff should review the Treatment Plan and contact the Oncology team to release any prescribed antiemetics to the MAR. The suggested order of escalation for breakthrough nausea and vomiting is outlined in the above table. This should be adjusted for individual situations. 
Consideration should be given to the contribution of anticipatory nausea and vomiting which is likely to respond better to benzodiazepines and non-pharmacologic management.  
Delayed CINV 
This is defined as CINV occurring 1-5 days after chemotherapy and is most associated with anthracyclines or platinum agents such as Cisplatin or Carboplatin. Regular antiemetics should be continued for at least 48 hours after completion of Cisplatin
            and in any other course of chemotherapy where delayed CINV has occurred in the past. Note: agents that cause delayed CINV may require antiemetics for up to 5 days following completion of chemotherapy. 
Consideration may be given to a second dose of Fosaprepitant  or a second dose of Palonosetron if this is appropriate. Ongoing Dexamethasone and Ondansetron may be sufficient.  
Further
considerations 
- Anticipatory CINV, is common in      adolescents and rarely responds to standard antiemetic regimes.      Benzodiazepines can be useful in this patient population but do not have      direct antiemetic effects. The best treatment for anticipatory CINV is
                             prevention- if patients do not associate chemotherapy with nausea or      vomiting, anticipatory CINV may not develop
- Dexamethasone should be charted      regular (not PRN) if included in antiemetic regimes as the efficacy is      enhanced with prophylactic administration
- Delayed CINV is common after      chemotherapy courses containing Cisplatin. Antiemetics should be continued      regularly for at least 48 hours after completing chemotherapy
- Ondansetron is as effective as Granisetron      and is the 5HTз (serotonin) antagonist of choice for CINV. If Granisetron      has been administered pre/post operatively, change antiemetic coverage to Ondansetron      if child commencing chemotherapy (may commence administration of Ondansetron
                             12 hours post Granisetron; use in caution in patients with prolonged QT      intervals or on multiple QT prolongating drugs, discuss with fellow or      consultant prior to prescribing). Ensure Granisetron is ceased. 
Non-pharmacological management of CINV 
 
Despite the advances in pharmacological management, standard pharmacological regimes may not fully alleviate symptoms of CINV in paediatric oncology patients. Non-pharmacological interventions are an important consideration of antiemetic therapy. Non-pharmacological measures
            should be implemented in conjunction with pharmacological regimes to allow for the effective management of CINV. The use of non-pharmacological measures may not be appropriate for each patient, interventions should be implemented according to the individual patient's needs and circumstances.
                 
    
Music therapy and
relaxation 
 
Music therapy and relaxation are beneficial interventions in managing CINV with minimal negative side effects. Music therapy may include a) live and active music engagement, and b) individual (recorded) music listening for refocusing and/or relaxation. These interventions are suitable for all ages,
            are cost effective and can be implemented in the inpatient, outpatient and home environments. The music therapist is available to assess and advise on the most suitable plan for each patient. 
Music listening/relaxation during chemotherapy:
- Where possible suggest to families to bring familiar music and music playing device for the first period of chemotherapy 
- Involve a music therapist to assess the capability of children receiving chemotherapy to use music independently 
- Encourage patients to listen to recorded music that is familiar and that they find comforting and relaxing during periods of chemotherapy (familiar music is the best option)
- For patients and families needing guidance the music therapist can make recommendations about styles of music that are effective in promoting relaxation for different age groups 
- Commence music listening prior to chemotherapy administration or during experiences of anticipatory nausea and vomiting 
- Contact Music Therapy, Educational Play Therapy or Comfort First Clinicians to assess if patient may benefit from focused breathing exercises to assist relaxation
- Encourage periods in a quiet environment
- Cluster medical and nursing care to allow for periods of rest                    
        
 
For children aged under 7 years, active music engagement may be more effective than passive music listening. The Music Therapist can advise/plan for this. See also section on Cognitive Distraction.   
Guided imagery 
Encouraging patients to focus on thoughts and images they find pleasing and relaxing will divert attention from nausea and vomiting to desirable thoughts and images. 
- Encourage patients to visualise images related to the external environment (nature, landscape images) prior to and during chemotherapy administration
- Place appealing images/paintings in patients' rooms during chemotherapy administration
- Encourage patients to reside in areas where they can enjoy the outside view (e.g. by windows) during periods of nausea, vomiting and anxiety
- Implement music listening in combination with guided imagery for optimal management of nausea and vomiting   
Cognitive
distraction 
 
Cognitive distraction acts to counteract CINV by drawing a patient's attention away from feelings of nausea and vomiting and focusing attention on more pleasant activities. Patients should be encouraged to participate in  
- Computer games
- Movies/Television
- Arts and crafts
- Developmental / Group play sessions
- Active Music Engagement 
- Education sessions (kinder and school)
- Socialisation with family, friends and other patients 
- Discussions about life outside of the hospital setting (pets, siblings, school, hobbies)
- Organising visits from volunteer services and ward grandparents available at the RCH  
The Educational Play Therapy, Art Therapy and Music Therapy teams can assist in providing activities that promote cognitive refocussing to effectively manage CINV.  
Massage 
Educating families to perform massage during periods of chemotherapy has a positive impact on reducing levels of stress, anxiety, nausea and vomiting.          
    
It is not recommended to
use massage for the paediatric oncology patient with a low platelet count
(platelets ≤ 20-30 x 10e9/L)
- Caution should be taken in patients      receiving radiation. Avoid massaging areas that have received treatment to      reduce irritation of irradiated skin and/or skin breakdown 
- Caution should be taken in patients      with solid tumours. Avoid massaging directly over areas where tumour is      present to reduce associated pain and anxiety
- The level of pressure applied to      the patient should be adjusted in those at risk of peripheral neuropathy
- Care should be taken to minimise      massage movements that create a rocking motion in patients with nausea and      vomiting 
- Use non scented oils to reduce      nausea associated with oil scents 
- Care should be taken in patients      with an accessed port (central venous access device) to avoid trauma  
Acupressure 
 
The acupressure technique involves the pressure applied to and then released from acupoints. Acupressure may be performed manually or with wrist pressure bands (also used for motion/travel sickness).
It is
not recommended to use acupressure for the paediatric oncology patient with a
low platelet count (platelets ≤ 20-30 x 10e9/L)
- Acupressure wrist bands may be      applied to children prior to and during chemotherapy administration as      tolerated
Manual
acupressure
- Perform daily during chemotherapy      administration in the absence of acupressure wrist bands
- Pressure should be applied to      acupoints for 1 to 3 minutes and then released 
- Acupressure should commence prior      to administration of chemotherapy and continue for the duration of the      chemotherapy cycle 
- Health professionals should      familiarise themselves with the P6 acupressure technique. Adult studies      have suggested pressure to the P6 acupoint may assist in the control of      nausea and vomiting. The P6 acupoint is located on the inner forearm,
                             located 3 fingerbreadths below the wrist, between the two tendons.
- Encourage patients and families to      familiarise themselves with the P6 acupressure point technique so they can      independently perform this technique during treatment periods  
Dietary
considerations 
 
The following suggestions may be useful to help manage nausea and vomiting;
- Offer      bland, dry foods such as toast and dry biscuits
- Offer      smaller serves of food more frequently
- Offer sips of      fluid throughout the day, sucking on ice cubes, fizzy drinks such as soda      water or dry ginger ale and jellies can assist with an upset stomach
- Offer      cold foods that have little smell
- Eat meals in a well      ventilated room to clear the smell of foods away
- Encourage      oral intake during times when the child feels less nauseated 
- Discuss      with your doctor/medical team about optimising anti-emetics
Enteral
nutrition (Nasogastric/PEG feeds) 
 
- Consider      reducing the rates of NG/PEG feeds during highly emetogenic chemotherapy
- If a child is      vomiting during NG/PEG feeds, consider pausing the feeds for a short      period (e.g. 1 hour) and restarting again at the last tolerated rate. If a      child is on overnight NG/PEG feeds consider running total volume,      prescribed by the dietitian, over 24 hours
- A dietitian can      help to alter a child’s feeding regime if needed. Please refer to the      dietitian for advice.  
Other
considerations 
- A multidisciplinary approach to      managing CINV will assist in providing appropriate supportive care and      effective antiemetic regimes to the paediatric oncology patient
- Current literature supports the use      of ginger supplementation to manage general nausea and vomiting, however      ginger is not recommended for use in the paediatric oncology population      due to unknown effects on coagulation
- Poorly controlled CINV can result      in dehydration, electrolyte imbalance, anorexia and fatigue 
- Antiemetic therapies should be      routinely administered during chemotherapy administration known to induce      nausea and vomiting, not just PRN when patients develop symptoms of nausea
- If a patient is being discharged      with antiemetic medications, the patient and/or caregivers should be given      instructions on the management of antiemetic regimes at home prior to      discharge
- The use of various forms of non-pharmacological      and complementary therapies has also found to reduce nausea, vomiting and      fatigue intensity, however should be discussed with the medical team prior      to use 
- Rinse the mouth thoroughly after
     vomiting with water (stomach acid left in contact with the teeth and the
     mouth lining will cause tooth decay and irritate the mouth)
