The purpose of this guideline is to provide guidance about intrathecal cytotoxic chemotherapy administration via a lumbar puncture or Ommaya reservoir at Great Ormond Street Hospital (GOSH).
Note: While this guideline refers to the ‘child’ throughout, all activities are applicable to young people.
Cytotoxic intrathecal medication can only be administered by injection through an Ommaya shunt reservoir or by performing a lumbar puncture (Dougherty and Lister 2011).
Only methotrexate, cytarabine (Cytosine arabinoside, Ara-C) may be administered via the intrathecal route. Intrathecal hydrocortisone is often given at the same time as intrathecal methotrexate and cytarabine (GOSH 2016).
Cytotoxic intrathecal medication must only be administered by a suitably trained and authorised doctor whose name is on the GOSH Intrathecal Register.
The GOSH Intrathecal Register document names all staff involved in the clinical screening, final checking, dispensing, delivering, checking and administration of intrathecal chemotherapy. Paper copies of the register are kept in all areas where intrathecal chemotherapy is prescribed and administered. It is also available electronically.
Refer to the specific national and local guidelines that exist in relation to administration of cytotoxic intrathecal medication (GOSH 2016).
It is the responsibility of the individuals on the GOSH Intrathecal Register to ensure that any colleagues they involve in the process are on the register for the task in question (GOSH 2016).
All nursing staff should receive training in the risks associated with the administration of cytotoxic intrathecal chemotherapy. This should be appropriate to their level of involvement in the prescribing, verification, handling, preparation and administration of intrathecal chemotherapy (GOSH 2016).
Intrathecal chemotherapy must be issued by pharmacy at a different time from intravenous chemotherapy (GOSH 2016).
Ensure the intrathecal medication prescribed is compatible with this route of administration (GOSH 2016).
Intrathecal cytotoxic medication must be prescribed on a designated cytotoxic intrathecal chemotherapy drug chart, either by hand or by using Chemocare® (GOSH 2016).
Refer to hospital prescription guidelines. The medication and route of administration, 'INTRATHECAL', must be clearly written in full block capitals on the chart (GOSH 2016).
Intrathecal and intrareservoir chemotherapy doses will be dispensed in syringes which will not connect with intravenous luer connectors (National Patient Safety Agency (NPSA) /2009/PSA004A). (Rationale 1).
All intrathecal chemotherapy doses must be packed individually and separately from all other drugs, in a specially designated intrathecal chemotherapy bag. The outer bag must be labelled with the patient's name, ward and the words ‘for intrathecal use only' (GOSH 2016).
Contra-indications of the medicine (intrathecal chemotherapy):
- nausea and vomiting
- altered neurological status
- arachnoiditis (inflammation of arachnoid lining caused by infection) (Killeen et al 2012, Bogod 2012). The arachnoid layer is one of the three layers of the brain and spinal cord
- reduced white and red cell blood count
- medication formulary
- treatment protocol
- patient's medical notes with current dated treatment protocol
- manufacturer's drug information (if required)
- intrathecal medication and prescription
- sterile dressing pack
- alcohol-based antiseptic ChloraPrep®, 2% chlorhexidine in 70% isopropyl alcohol*
- lumbar puncture needle (specifically designed needle that will not connect with intravenous syringes) (NPSA/2009/PSA004A) (Rationale 1)
- sterile gauze squares
- Op-site® spray or similar
- sterile gloves
- sterile field
*2% chlorhexidine gluconate in 70% isopropyl alcohol should not be used on the skin of pre-term infants under 35 weeks gestational age. It can be used with caution in children under two months of age. However, if there is any evidence of skin reaction in this age group, discontinue its use and consult the following for further advice:
- Tissue viability CNS.
- Vascular Access Team.
Alternative antiseptic solutions:
- Povidone-iodine 10% (aqueous)
- 0.5% chlorhexidine gluconate in 70% isopropyl alcohol.
Intrathecal medication must only be administered by a suitably trained doctor (GOSH 2016).
Intrathecal chemotherapy must only be given within working hours (between 8.30am - 5.30pm) (GOSH 2016).
Intrathecal chemotherapy to be administered with general anaesthesia, local anaesthesia or Entonox® must only be administered in a designated area on a designated haematology/oncology list (GOSH 2016) (Rationale 2).
At GOSH these designated areas are:
- general anaesthetic procedure room on Safari Day Care
- main VCB theatres
- Morgan Stanley theatres
If for any reason intrathecal chemotherapy cannot be given in a designated list, the patient’s consultant must complete an exception report. This must state the reasons why this is not possible and who will be available to give and check the intrathecal chemotherapy. The pharmacist will deliver the dose directly to the doctor (GOSH 2016) (Rationale 4).
If general anaesthesia or Entonox® is to be administered, then an anaesthetist or staff competent in the administration of Entonox® must be present ensure patient safety. The child must be starved according to hospital policy (Rationale 5).
Check intrathecal chemotherapy using procedure checklist sticker. This sticker is placed in notes post procedure. Stickers can be found in each designated area where intrathecal chemotherapy is administered with the intrathecal register.
The doctor who will administer the intrathecal medication must, together with a nurse on the intrathecal register, check patient’s treatment protocol and determine stage of treatment (Rationale 6). This must be the dated copy in the patient's medical notes. There must also be an entry in the notes stating that the patient is fit for the procedure. The doctor who will administer the intrathecal medication must also check the patient’s full blood count and that this is recorded in patient’s health care record, Minimum platelet count for the procedure needs to be 50 X 9/10 L (Rationale 7).
Clotting screen should be checked at diagnosis, a further check prior to the procedure is not necessary unless patient is unwell (e.g. septic, potential abnormal liver function tests) (Rationale 7).
Check patient’s consent form, drug chart and name band. Nurse/doctor to sign on intrathecal prescription and print names to confirm they have checked the patient's identification (Rationale 8).
Doctor to collect intrathecal chemotherapy from designated fridge and sign book and chart using full signature, to confirm that the chemotherapy has been collected from a designated area (GOSH 2016, Department of Health 2008) (Rationale 4).
Check medication according to medicine administration policy. Sign on the prescription in the medication checked section. The nurse witnessing the procedure must also sign in the relevant section. Both the doctor and the nurse must use their full signature and print their names (Department of Health 2008, GOSH 2016) (Rationale 8).
Administration via a lumbar puncture
As soon as the child is anaesthetised, they should be monitored with an oxygen saturation monitor and the following must also be observed:
- respiratory rate and pattern (Rationale 9)
- heart rate
- airway (Rationale 10)
- conscious level (Rationale 11)
Put on apron and personal protective clothing ie visor and sleeves (Rationale 13).
Perform a hand wash as per hospital policy (Rationale 14, 15, 16).
- Open sterile dressing pack and alcohol-based antiseptic ChloraPrep®, 2% chlorhexidine in 70% isopropyl alcohol or alternative (see Preparation of equipment).
- The nurse assisting with the procedure will open intrathecal chemotherapy drugs by cutting open plastic sealed pack and place this non sterile item on a tray separately from the sterile field
- Perform a hand wash as per hospital policy (Rationale 14, 15, 16).
- Put on Sterile gloves.
- Prepare skin and clean site using ChloraPrep®, 2% chlorhexidine in 70% isopropyl alcohol Or alternative (see Preparation of equipment).
- Allow to dry (Rationale 14).
Insert a lumbar puncture needle and collect 20 drops of cerebrospinal fluid (CSF) (Rationale 17).
Connect syringe containing chemotherapy to lumbar puncture needle, and inject slowly. Repeat process for double and triple injections. No flush is required between these medicines (Rationale 18, 19).
Remove the needle and syringe when the administration is complete.
Apply pressure with gauze pad when CSF has stopped leaking. Spray with Op-site®. If CSF continues to leak, apply a small dressing with gauze and tape (Rationale 20).
This dressing must be removed within 24 hours post the procedure, or as soon as the leak has stopped (Rationale 14).
Clear away equipment according to hospital waste management policy (Rationale 22).
Wash hands according to hospital policy (Rationale 15).
The doctor and the nurse must sign, using full signatures and print names, for administration of medication on the child’s prescription chart after administration is completed (Department of Health 2008, GOSH 2016) (Rationale 23, 24).
The doctor will document procedure in patient’s medical notes.
Post procedural care
If recovering from general anaesthetic or sedation, the child should continue to have their vital signs monitored and recorded until they are fully awake (Rationale 25).
The lumbar puncture site should be observed (Rationale 26) and nursing staff must be aware of side effects and complications of the procedure and of the drugs that were given.
- bruising at site
- arachnoiditis (inflammation of arachnoid lining caused by infection. (Killeen et al 2012, Bogod 2012). The arachnoid layer is one of the three layers of the brain and spinal cord)
- nausea and vomiting
If any of these occur they must be recorded in the nursing notes and the doctor should also be informed (Rationale 27).
Whilst waiting for the child to regain consciousness, the noise levels in the room should be kept to a minimum (Rationale 28).
Once the child is rousable the child’s parents should be invited to return (Rationale 28).
The child should be taken back to their bed and if they wish to sleep, they can be placed in a semi prone position (Rationale 29).
If awake, the child can be nursed in any position that they are comfortable (Rationale 30).
Oxygen and suction should be available by the child’s bed (Rationale 31).
Give analgesia if required (Rationale 30).
Administration via an intraventricular access device (Ommaya reservoir)
The doctor performing the procedure must be deemed competent to access the reservoir (Rationale 19).
To be administered with local anaesthesia, such as Emla® or Ametop® (Rationale 30).
- Check medication according to current medicine administration policy (see Performing the Procedure: general principles)
- Position the child comfortably on parent's lap or lying down (Rationale 30).
- Put on apron and personal protective clothing i.e. visor and sleeves (Rationale 13, 15).

- Insert small non-coring butterfly needle (23 or 25 gauge ) device which cannot connect to intravenous Leur connectors, (NPSA/2009/PSA004A) access the reservoir and collect a small amount of CSF (Rationale 17, 32).
- Connect syringe containing chemotherapy to butterfly needle extension and inject the medicine slowly. Disconnect the syringe.
- Attach syringe with normal saline 0.9% for injection to the butterfly needle extension, flush with normal saline 0.9%, equivalent amount to the volume of chemotherapy given. Remove the butterfly extension needle from the reservoir.
- Compress and release dome after all medication is given (Rationale 33, 34).
- Remove the needle and syringe or syringe when the administration is complete.
- Apply pressure with gauze pad. When CSF stops leaking, spray the site with Op-site spray® (Rationale 20).
- If CSF continues to leak, apply a small dressing with gauze and tape. This dressing must be removed within 24 hours post the procedure, or as soon as the pressure dressing is no longer required (Rationale 26).
