The purpose of this guideline is to provide guidance about patient controlled and nurse controlled analgesia at Great Ormond Street Hospital.
The use of patient controlled analgesia (PCA) and nurse controlled analgesia (NCA) has been shown to provide a safe and effective technique for the administration of intravenous or subcutaneous opioids for the relief of pain (Anderson et al 1998; Bray 1983; Doyle et al 1993; Llewellyn 1993; Howard et al 2008; Lloyd-Thomas and Howard 1994).
These techniques are most commonly used following surgery, but can also be effective for the management of non-surgical pain such as sickle crisis, pancreatitis and cancer related pain. With caution, PCA or NCA can also be used to manage pain prior to surgery, eg fractures and abdominal pain.
Morphine is considered to be the gold standard for intravenous analgesia and is therefore usually the opioid of choice (Lloyd-Thomas 1994). The use of other opioids, eg fentanyl or oxycodone, may be considered when morphine is contraindicated, or as a preferred alternative. Other drugs with analgesic properties, such as ketamine, may be administered (as an adjunct) in combination with an opioid in some circumstances (Schmid 1999). In restricted circumstances, where opioids are contraindicated, ketamine alone may be used (White et al 2006).
Throughout this document the term 'analgesic solution' will be used to refer to the specific drug or drugs prescribed in solution.
Throughout this document the term 'patient controlled analgesia' (PCA) refers to a method of pain control that allows the patient to press a button to self-administer a pre-programmed amount of an intravenous or subcutaneous analgesic solution (the bolus dose). The pump programming will determine the time before another bolus dose can be administered, known as the 'lockout' time. The patient may also receive a small background infusion of the analgesic solution.
The term 'nurse controlled analgesia' (NCA) refers to a technique by which the nurse (or other health professional licensed to administer medications) may press a button to give the patient a pre-programmed amount of an intravenous or subcutaneous analgesic solution (the bolus dose). The bolus dose can only be repeated after a set period of time (the lockout period). The patient may be given a larger continuous infusion of the analgesic solution. However, with the exception of intensive care areas, the pump is programmed with a longer lockout interval (20-30 minutes).
Some patients may benefit from using a dual technique, whereby either the patient or the nurse is able to press the button on a pump with NCA settings. This must be approved by the Pain Control service and documented clearly on the Pain Management chart. For some patients, daytime PCA and night-time NCA settings may be appropriate. This can promote a restful night, while allowing the patient to maintain control throughout the day. Both these techniques are used at the discretion of the Pain Control service.
Some patients should not receive a background infusion, eg neonates or patients with renal impairment. These groups and patients with an altered level of consciousness will require particularly close monitoring for potential complications.
The use of PCA and NCA requires a specially designed, locked pump which allows for programming of a continuous infusion rate (if required), a bolus dose and lockout interval. The pump used in the Trust (IVAC® PCAM) also requires the programming of a drug concentration and a four hourly maximum dose limit (400mcg/kg (maximum 20mg) in any four-hour period).
PCA/NCA pumps must only be initially programmed by an anaesthetist or member of the Pain Control service. Adjustments can then be made within protocol by competent nurses as defined below.
All personnel who care for patients receiving PCA or NCA must be trained and able to do so safely.
The Pain Control service can be contacted on bleep 0577, 24 hours a day. The Pain Control service nurses are available to deal with any pain-related problems from 8am to 8pm Monday to Friday and 9am to 3.30pm on Saturday. The service is provided by the duty anaesthetist and the clinical site practitioners outside of these hours.
Abbreviations and definitions used throughout this document
mcg = micrograms, mg = milligrams, ml = millilitres, kg = kilograms
Competent nurse - a nurse who has attended the GOSH advanced practice day and been assessed as competent in adjusting PCA/NCA programming. Some nursing staff, such as clinical site practitioners, or those practising in particular areas (recovery etc) will be authorised to undertake a wider variety of roles than others, such as clinician override bolus administration.
Pain Control service - encompasses the healthcare professionals within the Pain team, those who deputise for them and duty anaesthetists.
PCA - patient controlled analgesia, NCA - nurse controlled analgesia.
Within this document, the term child will be used to signify infants, children and young people.
Further recommendations for optimising pain control in children are included in the References section of this guideline.
Prior to surgery/setting up the infusion the anaesthetist or Pain Control service staff will consider:
If the patient is to use PCA they must:
All parents should be given a copy of the leaflet entitled Pain relief for your child after surgery PCA and NCA (PDF, 91KB) (Rationale 3).
This is also available on the wards and can be obtained from the Family Resource Centre (Rationale 3).
An anaesthetist or competent nurse will discuss the use of PCA/NCA with the child and family prior to surgery/setting up the infusion (Rationale 4).
The child and family should be prepared for the PCA/NCA:
The nursing staff and/or play specialist should explain the technique to the child and family (Rationale 5, 6).
Parents should be advised in a sensitive manner that they are not permitted to administer a bolus by pressing the button in either technique and that this is a safety feature of the technique (Rationale 7).
The family should be made aware that if the child is unable to use PCA the programming can be changed to NCA, but that this requires adjustment of the pump programming (Rationale 8).
NCA may be changed to PCA if the child is able and willing to press the button and understands the concept (Rationale 9).
If the family have any questions that ward staff are unable to answer, they should contact the Pain Control service on bleep 0577.
Nursing staff should also ensure that an age appropriate pain assessment tool and documentation is available (Rationale 10).
Nurses should ascertain which tool is best suited to the child bearing in mind the following principles:
- Self-report is the gold standard and should be used whenever possible (eg Wong-Baker FACES™, numerical rating scale).
- The tool proposed should be discussed with the child and family.
The child may be asked to score a previous painful experience to determine whether they are able to use the tool.
Words the child uses for pain and the child’s usual pain related behaviour should be recorded.
For infants, patients who are cognitively impaired and those unable to communicate, use an appropriate observational tool and involve carers as much as possible.
The following baseline observations should be recorded before the child goes to theatre or uses the PCA/NCA (Rationale 11):
- pain assessment using a validated tool
- heart rate
- respiratory rate
- blood pressure
- oxygen saturation
- baseline sedation score
Preparation of equipment: drugs used
Drug: morphine sulphate
Mechanism of action: binds with opioid receptors in the brain and spinal cord to alter the transmission of impulses along the pain pathway.
Available in ampoules of: 5mg/ml, 10mg/ml, 30mg/ml (hence the need for caution that correct ampoules selected). NPSA alert restricts the use of 30mg/ml ampoules to certain clinical areas only.
Standard concentrations are:
Mechanism of action: binds with opioid receptors in the brain and spinal cord to alter the transmission of impulses along the pain pathway.
Available in ampoules of: 10mg/1ml in 1ml or 2ml ampoules.
Standard concentrations are:
- Intravenous: refer to protocol on prescription.
- Patient weighs less than 50kg: 1mg/kg in 50ml of 0.9% sodium chloride or glucose 5% (1ml = 20mcg/kg).
- Patient weighs more than 50kg: 50mg in 50ml of 0.9% sodium chloride or glucose 5% (1ml = 1mg).
Mechanism of action: binds with opioid receptors in the brain and spinal cord to alter the transmission of impulses along the nerve axon.
Available in ampoules of: 50mcg/ml in 2ml or 10ml ampoules.
Standard concentrations are:
Action: ketamine is an NMDA receptor antagonist (not an opioid), which is thought to act within the brain and spinal cord to modify the transmission of painful messages (Schmid 1999).
Available in ampoules of: 10mg/ml (20ml ampoule), 50mcg/ml (10ml ampoule).
Intravenous or subcutaneous: refer to protocol on prescription.
It should only be prescribed after discussing the patient with a consultant anaesthetist.

instant reversal of opioid-induced respiratory slowing or respiratory arrest
has a short half-life of 30 minutes. Dose may need to be repeated.
Available in ampoules of: 20mcg/ml and 400mcg/ml.
Can also be given intra-muscularly or subcutaneously if the intravenous route is not available.
Preparation: disposables ordering
Clinical areas are expected to stock appropriate disposables for their patients (Rationale 12).
Administration sets can be ordered on a top up system through the Procurement department. For reasons of patient safety, all administrations sets used for PCA/NCA should contain an anti-siphon valve (Southern and Read 1994).
For example: anti-siphon intravenous administration set – ORDER REF: 30862.
For patient safety reasons, all administration sets used to piggyback a PCA/NCA infusion onto maintenance fluid should contain an anti-syphon valve and an anti-reflux valve.
For example: anti-siphon intravenous administration sets with Y connector - ORDER REF: 30852.
Products with other order codes may also be suitable.
Preparation: setting up infusions
The majority of PCA and NCA pumps will be prescribed and set up in theatres after surgery. However, contact the Pain Control service on bleep 0577 if a PCA/NCA is required for a patient on the ward (Rationale 13).
The Pain Control service will request the referring clinician to write a brief summary of the child’s condition and need for analgesia in the case notes (Rationale 14). A prescription will be generated by either an anaesthetist or Pain Control service nurse prescriber.
A pain management chart and drug prescription chart should be completed by the person prescribing the PCA/NCA (Rationale 15). The prescriber should check that the patient has no other current opioids prescribed to minimise risk of accidental administration and adverse side effects. The PCA/NCA must also be recorded on EP.
Prescriptions are available in main theatre reception files or on the Pain Control service website. These should be printed on yellow paper.
Out of hours, patients requiring PCA or NCA should be listed on the Pain Control service board in main theatres.
The pain management chart outlines standard protocols for intravenous morphine only. All other regimens will have the relevant protocol printed on the back of the yellow prescription chart, also available on the website or from main theatre reception in the Variety Club Building (VCB).
It is particularly important to ensure that naloxone has been prescribed correctly before the patient leaves theatre or the infusion is commenced (Rationale 16).
Equipment for commencing PCA/NCA includes:
The PCA/NCA pump must only be initially programmed by an anaesthetist or member of the Pain Control service. The serial number of the pump, and all of the shaded patient detail sections, must
be recorded on the pain management chart (Rationale 22
All pumps should be kept locked while in use and a dedicated line should be used wherever possible for NCA or PCA (Rationale 23
). The anti-siphon line should be connected directly to the patient's intravenous access (Rationale 21
Standard pump programming and drug concentrations should be used at all times, unless approved by a member of the Pain Control service (Rationale 24
). Refer to the front of the pain management chart or drug-specific protocol for standard settings by weight and age. All out-of-protocol settings should be clearly marked as such on the pain management chart.
Standard intravenous programming
Check front of pain management chart, or drug-specific protocol for further restrictions depending on age, weight and renal function.
- background: 0, 0.2, 0.5 or 1ml/hr
- bolus dose: 0.5ml or 1ml
- lockout: 20 or 30 minutes
- ITU only: five minutes
In some circumstances, eg poor intravenous access, subcutaneous infusion may be preferred (Rationale 25
). The infusion prescribed for subcutanous administration is more concentrated than the intravenous prescription (drug diluted to 20ml infusate rather than 50ml for IV), hence smaller background and bolus volumes are required to administer the same dose subcutaneously.
Standard subcutaneous programming is:
- background: 0 or 0.1ml/hr
- bolus dose: 0.2ml or 0.4ml
- lockout: 5 or 10 minutes
- background: 0, 0.2, or 0.4ml/hr
- bolus dose: 0.2ml or 0.4ml
- lockout: 20 or 30 minutes
- ITU only: five minutes
The speed at which the bolus dose is delivered will be slowed for subcutaneous delivery to minimise discomfort. Specific subcutaneous protocol should be placed in patient folder. The use of an appropriate subcutaneous administration device (such as a Thalaset®) is strongly advocated.
When the PCA/NCA is commenced, the Pain Control service may administer an initial loading dose of (Rationale 26):
- morphine sulphate: 50-100 micrograms/kg or
- fentanyl 0.25-1 micrograms/kg
This is particularly important for patients in severe pain, eg patients with sickle cell crisis or severe mucositis.
Care of patient while receiving PCA/NCA analgesia
All children receiving intravenous opioids must be supervised by a registered nurse, doctor or appropriately trained ODP.
Any child leaving a clinical area while receiving PCA/NCA analgesia must be accompanied by a registered nurse, doctor or appropriately trained ODP.
If the PCA/NCA has been set up in theatre a verbal report should be made to the recovery nurse. This should include:
details of intra-operative analgesia, loading dose and other drugs given
details of drug concentration and pump programming
- any pain related complications that have been experienced peri-operatively
- the pain assessment scale being used by the patient and/or carer, if known, or some indication of the child's pre-operative competence to self report if known.
All these details should be documented clearly on the patient’s pain management chart (Rationale 27).
In addition to this and at any subsequent patient handover between staff, both staff concerned should check that:
- The PCA/NCA prescription chart has been completed correctly (Rationale 28), the analgesic solution and drugs to prevent side effects are prescribed (Rationale 29).
- PCA/NCA recorded on the Electronic Prescribing system (EP).
The drug and dose being administered corresponds with the prescription chart (Rationale 30).
The pump programming corresponds to the most recent entry in the pain management chart (Rationale 31).
Pump settings are within protocol for the age and weight of the child, unless clearly indicated as out of protocol with rationale for this. Check against the pain management chart for intravenous morphine or the drug specific protocol for other regimens.
The patient’s pain is being managed effectively.
The patient is not excessively sedated.
Ensure appropriate dose of naloxone is prescribed (Rationale 32).
Prescribed anti-emetics are not duplicated on EP or the standard ward drug chart.
Other analgesics (such as paracetamol and NSAIDS) are prescribed and administered where appropriate (Rationale 33).
These checks are also applicable if the PCA/NCA is set up on the ward before commencing an infusion.
Record pain scores hourly on the pain assessment chart (Rationale 34).
Self-reporting should be used whenever possible.
The type and location of pain should be identified whenever possible.
Hourly pump readings should be recorded on the PCA/NCA observation chart (Rationale 35). This should include:
- number of demands (tries)
- number of successful demands (good tries)
- amount infused (hourly and running totals)
- syringe reading at least four hourly (though hourly recording is recommended) (Rationale 36)
- presence or absence of opioid associated side effects (see below)
Never re-zero the pump (Rationale 37).
Supplementary analgesia, eg paracetamol and an NSAID (either diclofenac or ibuprofen) where appropriate, should be given regularly if either the oral or rectal route is available. Intravenous administration of paracetamol should be considered for all patients where enteral administration is not possible (Rationale 38).
No supplementary opioids (such as codeine or tramadol) should be administered while the patient is receiving PCA/NCA, unless specifically ordered by an anaesthetist or the Pain Control service.
If patient is in pain explore the cause of the pain with the patient if possible:
Involve parents, play specialist and teacher (ie for distraction, reassurance, comfort measures etc) particularly if the pain is anxiety related (Rationale 39).
Administer prescribed simple analgesics, eg paracetamol and an NSAID (either diclofenac or ibuprofen) if appropriate (Rationale 40).
Administer prescribed adjuncts as appropriate, eg anti-spasmodic or anti-convulsant drugs (Rationale 41).
For PCA: encourage the patient to give a bolus and evaluate effectiveness after 10-15 minutes (Rationale 42).
For NCA: administer a bolus and evaluate effectiveness after 10-15 minutes.
If pain score is greater than four for more than an hour and boluses have been optimised, contact the Pain Control service on bleep 0577, or competent nurse to discuss making changes within protocol limits for the technique.
The surgical team or the child's physician should be contacted for advice if the pain could be indicative of new or escalating medical or surgical symptoms (Rationale 43).
All patients are reviewed at least once a day by a member of the Pain Control service (Rationale 44).
Pump programming must only be changed by a member of the Pain Control service or competent nurse (Rationale 45).
Increase the background infusion, or consider increasing bolus size, within protocol if:
- an accurate pain assessment is been undertaken and
- the patient has pain which has not resolved after frequent boluses and
- other interventions have been tried and have not been effective (regular simple analgesia, repositioning etc)
Decrease the background infusion if the patient is:
- experiencing opioid induced side effects, is pain-free and/or is requiring minimal boluses (Rationale 46)
Competent nurses in certain specified areas may also administer additional boluses (using the clinician override function) if required (eg clinical site practitioners, recovery staff, cardiac unit prior to chest drain removal)(Rationale 47).
All changes to pump programming should be reported to the Pain Control service on bleep 0577, and charted and signed for on the child's pain management chart.
Prevention and detection of opioid related side-effects
The sedation level of the child must be observed and recorded on the child’s PCA/NCA observation chart (Rationale 48).
Sedation scores should be recorded at least hourly:
The scores are as follows:
0 = awake
1 = sleepy/responds appropriately
2 = somnolent/rousable to light stimuli
3 = deep sleep/rousable (deeper physical stimuli)
4 = unrousable to stimuli
CEWS scores should be undertaken in line with Trust policy and additionally if the sedation score is greater than 2. CEWS escalation plan should be followed in all instances.
If the patient has a sedation score of four:
STOP the infusion (Rationale 49) and ensure the child is well supervised.
Contact the Pain control service on bleep 0577 and ward medical team.
The infusion may be recommenced once the sedation score returns to two, or on instruction from the Pain Control service.
These actions must be recorded in the child’s healthcare records (Rationale 50).
- The Pain Control service or competent nurse may decide to change the pump programming.
The following patients should be monitored continually using pulse oximetry (Rationale 51):
patients whose sedation score is repeatedly greater than two
patients with respiratory complications or obstructed airway
patients with a known sensitivity to morphine/opioids
infants under six months of age
The patient’s respiratory rate should be recorded hourly (Rationale 52):
The frequency of observation and recording should be increased if the patient is excessively sedated or their condition deteriorates.
CEWS scores should be undertaken in line with Trust policy and the Trust CEWS escalation plan should be followed in all instances.
The patient’s minimum satisfactory respiratory rate is written on the PCA/NCA prescription chart by the prescriber. This is for guidance only and the nurse should also take into account:
If respiratory depression occurs:
STOP the infusion.
Administer intravenous naloxone as prescribed (Rationale 55). This may need to be repeated (Rationale 56).
Contact the Pain Control service on bleep 0577 (Rationale 57).
Document actions in the child’s healthcare records (Rationale 58).
If respiratory arrest occurs:
- STOP the infusion.
- Contact the clinical emergency team on bleep 2222.
Administer basic life support (Rationale 59).
Administer intravenous naloxone as prescribed.
Contact the Pain Control service (Rationale 60).
Record incident according to hospital policy (Rationale 61).
Nausea and vomiting
The patient should be assessed for nausea and/or vomiting at least hourly (Rationale 62).
Any nausea or vomiting reported should be scored on the PCA/NCA observation chart. Score the highest rating in the previous hour. The scores are:
- 0 = nil
- 1 = slight
- 2 = moderate
- 3 = severe
If the patient complains of nausea or has been vomiting:
- aspirating a nasogastric or gastrostomy tube
- repositioning the nasogastric tube
- Stopping oral intake.
Administer an anti-emetic (eg ondansetron) as prescribed - consider whether intravenous administration is required (Gan et al 2003) (Rationale 63).
Consider using an additional anti-emetic if the nausea/vomiting has not improved after an hour (Gan et al 2003).
If nausea/vomiting continues, contact the Pain Control service or competent nurse, who may reprogram the pump (Rationale 64).
Suggested changes include:
- Reducing or stopping the background infusion.
- Slowing down the speed at which a bolus is given (ie dose duration to one or two minutes).
- Dexamethasone may be considered if not contraindicated and nausea persists (Gan et al 2003)
Record actions in the child’s health care records (Rationale 65).
The patient should be observed for pruritus (itching) (Rationale 66):
Record pruritis on PCA/NCA observation chart. The scores are:
- 0 = nil
- 1 = slight
- 2 = moderate
- 3 = severe
Administer an anti-histamine as prescribed, eg chlorphenamine (Rationale 67).
Actions must be recorded in the child’s health care records (Rationale 68).
Contact Pain Control service or competent nurse to review if pruritis persists.
If pain control is good, reduction or discontinuation of any background infusion may be beneficial.
Pain Control service may consider the substitution of another opioid (such as fentanyl) for morphine as the analgesic solution (Rationale 69).
The database of patients at GOSH who have undergone PCA/NCA therapy indicates there is no evidence that intravenous opioid administration causes urinary retention in children. For this reason, retention in children on PCA/NCA should be treated as for any other child in hospital.
Record the patient’s urine output on their fluid balance chart (Rationale 70).
If the patient has not passed urine twelve hours after surgery/commencing PCA/NCA check fluid intake and consider abdominal ultrasound of bladder (Rationale 71).
If no palpable bladder/empty bladder on ultrasound, consider dehydration as a possible cause of anuria.
If the patient has a palpable bladder or urinary discomfort, try adjusting positioning, providing privacy, water-play to promote voiding (Rationale 72).
Ensure that the patient is pain-free (Rationale 73).
Contact the relevant medical team/surgeons to determine whether the patient needs to be catheterised (Rationale 74).
If the patient is catheterised:
Drug administration: technical issues
Intravenous morphine syringes and administration sets must be changed every 24 hours (Rationale 76).
These may be changed by any healthcare professional who is competent in the administration of intravenous drugs and authorised by the Trust to do so (Rationale 77).
The PCA/NCA pump should be put on hold (using the call-back facility initiated by maintaining pressure on the stop button), rather than switched off, during the syringe change or any other occasion when the programme is interrupted (Rationale 78).
Drug administration: technical problems
In line with the manufacturers instructions, all staff caring for children using NCA or PCA should have undergone pump specific training and be able to recognise the significance of alarm messages.
If the pump alarms:
Stop the infusion.
Check the display panel to identify cause of alarm (Rationale 79).
If the line has occluded:
- De-clutch the PCA drive mechanism before investigating the cause of occulsion or releasing any clamps to avoid delivery of excessive dosage when obstruction released.
- Check the cannula site.
- Check for kinks or closed clamps.
- Flush the cannula.
- Restart the infusion.
If the syringe is empty a new syringe (as per prescription) should be made up by a nurse who is competent in the administration of intravenous drugs.
If alarm is due to a flat battery, plug the pump into the mains.
If the pump is faulty, it will need to be replaced and returned to Biomedical Engineering with a label describing the fault (Rationale 80). Contact the Pain Control service on bleep 0577.
If the patient has reached their four hourly maximum infusion limit, or the cause of the alarm is unknown, put the device on hold and isolate the infusion from the patient by clamping the administration line. Contact the Pain Control service on bleep 0577.
If pain persists after the four hourly maximum dose has been reached, the Pain Control service may, after reviewing the patient, alter the prescription and increase the four hourly limit to 25ml. This must be clearly documented and reviewed within 24 hours.
Staff must ensure that faulty pumps are returned to Biomedical Engineering with the problem accurately described (Rationale 81).
Any pump which has been dropped or damaged must be taken out of service until checked by Biomedical Engineering (Rationale 82).
All PCA/NCA pumps are fitted with a Biomedical Engineering tracking device.
The PCA/NCA may be discontinued by any member of staff who is competent and prepared to accept responsibility for the change (Rationale 83). Consideration should be given to the clinical condition of the patient and the possibility of withdrawal (see weaning and withdrawal guidelines).
Criteria for stopping PCA/NCA include:
the patient is able to take analgesia via an alternative route and this is prescribed
the background infusion has been reduced or stopped
the patient is requiring minimal bolus doses
Background infusions of 0.5ml/hr and 1ml/hr are usually reduced before the NCA is stopped.
The PCA/NCA must be stopped by any nurse in the following situations (Rationale 84):
The Pain Control service must be informed that the infusion has been stopped. Discontinuation must be recorded in the child’s health care records (Rationale 85).
Maintain IV access and record pain scores for at least four hours (Rationale 86).
Clean the pump with damp cloth and detergent solution (Rationale 87).
Pumps are routinely deep cleaned by HSDU prior to annual service.
Return cleaned PCA/NCA pump to theatre when not required (Rationale 88).
