Much smaller volumes atomic number 18 acceptable in children (Rodger and King 2000, Corben 2005). The medicinal drug is injected into the denser part ofthe muscle fascia below the subcutaneous create from raw materials. This is ideal because skeletal muscles have fewer distract-sensing nerves than subcutaneous tissue and can charter giantr volumes of solution because ofthe rapid uptake ofthe drug into the bloodstream via the muscle fibres.This nub that IM injections ar less painful when administered jellly and can be employ to inject concentrated and sticker drugs that could damage subcutaneous tissue (Rodger and King 2000, Greenway 2004). Examples of drugs administered via this route argon analgesics, anti-emetics, sedatives, immunisations and hormonal treatments. It is important to actualize and understand potential complications associated with IM injections and that rapid absorption of the drugs whitethorn increase these lay on the lines (Foster and Hilton 2004).The administration of any medication can present a risk and, therefore, the nurse must be able to recognise the signs of an anaphylactic (allergic) reaction, with signs of, for example, urticaria, pruritus, respiratory distress, shock or even cardiac arrest. Inappropriate selection of lay and poor technique can increase the risk of longanimous injury and lead to pain, nerve injury, bleeding, accidental intravenous administration and stereotyped abscesses caused through repeated injections at one spot with poor blood flow (Rodger and King2000).AuthorJanet hunting watch is lecturer in adult nursing, City Community and Health Sciences, incorporating St Bartholomew School of Nursing and Midwifery, City University, London. email j.a.huntercity.ac.ukKeywordsClinical procedures Drug administration Injection techn ique Tliese keywords are ground on the subject headings from the British Nursing Index.

It requires persuasion and the exercise of professional judgement. Therefore, the administration of intramuscular (IM) injections requires the health anxiety practitioner to possess the knowledge and rationale of the directive principles that underpin these clinical skills.It is essential that all aspects of these techniques -anatomy, physiology, endurin g assessment, preparation and nursing interventions are evidence based so that the nurse can perform rubber and accountable practice (Shepherd 2002, NMC 2007). The aim of this article is to modify the nurses knowledge and skills on injection techniques. This article describes the practical, step-by-step approach for administering IM injections, which will embolden nurses to perform this skill safely and competently.NURSING STANDARDIntramuscular injection sendsThere are fiver sites that can be con sidered for IM february 20 vol 22 no 24 2008 35art & science clinical skills 37injections (Figure 1). The two recommended sites for IM injections are the vastus lateralis and the ventrogluteal sites (Donaldson and Green 2005, Nisbet 2006). However, when the patient is obese, rhe vastus laterahs is a better option (Nisbet 2006). When choosing an appropriate site for administration, the nurse needs to en current that the medication will be absorbed. The nurse needs to consider whether the patient is receiving regular M injections because the site will need to be rotated to avoid irritation, pain and sterile abscesses. plectrum will also be influenced by the patients physical condition and age. Active patients are more likely to have a greater muscle FIGURE 1 Sites for intramuscular injections (IM) Mid-deltoid site The mid-deltoid site is easily accessible but due to the size of the muscle the area should not be used repetitively and only small volumes shouid be injected. Tlie maximum volume should be 1ml (Rodger and King 2000).Tlie denser part of the deitoid must be used. It is Lisef j l to visualise a triangle whereby the horizontal line is turn up 2.5-5cm below the acromial process and the midpoint of the lateral aspect of the arm in line with the axilla forms the apex. The injection is given intimately 2.5cm down from the acromiai process, avoiding the radial and brachial nerves (Workman 1999, Rodger and King 2000). Dorsogluteal site Tliis a&3. is used for deep IM and Z-track injections. Up to 4mi can be injected into this muscle (Workman 1999, Rodger and King 2000).Commonly referred to as the outer fastness quadrant, it is located by utilize imaginary lines to divide the buttocks into four quarters. To identify the gluteus maximtis, ensure a line that extends from the iiiac spine to the greater trochanter of the femur. Draw a vertical line from the midpoint of the premiere line to identify the upper aspect of the upper outer quadrant This location avoids the original gluteal artery and sciatic nerve (Workman 1999, Small 2004). Rectus femoris site This site is used for deep I M and Z-track injections.Between mass than older or emaciated patients, so individuals will need to be assessed to see if they have sufficient muscle mass. If not, the muscles may need to be pinched up in the lead the injection (Workman 1999, Rodger and King 2000). Any area or presence of inflammation, swelling or infection should be avoided (Workman 1999) .Patient preparationIt is important to explain the procedure so that the patient fully understands and is able to give his or her informed consent and co-operation. The discussion should include the choice of site for the injection and information about the medication, action and side effects. The patient can then express any concerns or anxieties relating to the procedure and the patients knowledge can be l-5ml can be injected, although for infants this would be 1-3 mi. The rectus femoris is a large and well-defined muscle and is the preceding muscle of the quadriceps. I t is located halfway between the superior iliac crest and the patella (Workman 1999), Vastus lateralis site The vastus lateralis site used for deep IM and Z-track injections.Up to 5ml can be administered (Rodger and King 2000). The muscle forms part of the quadriceps femoris group of muscles and is located on the outer side of the femur. If is foLind by measuring a hands breafh from the greater trochanter and the knee joint, which identifies the middle third ofthe quadriceps muscle (Workman 1999).There are no major blood vessels or structures which could cause an injury in this area (Rodger and King 2000). Ventrogluteal site This site is used for deep IM and Z-track injections. This site is located by placing the medallion ofthe nurses hand on the patients opposite greater trochanter (for example, the nurses right palm on the patients left hip), then extending the index finger to the anterior superior iliac spine to make a V. The injection is then given into the gluteus medius muscle, which is the totality of fhe V (Workman 1999, Rodger and King 2000).Evaluated. It is important to check whether the patient has any known allergies to identify potential reactions to the medication. FVeparation ofthe equipment either the necessary equipment shouid be prepared before commencing the procedure to avoid any delays or interruptions during rhe procedure. The equipment required for administering I M injections is listed in Box I and preparation of rhe equipment is described in Box 2. The techniques used for administering IM injections are outlined in Box 3.Skin cleansing There are inconsistencies regarding genuflect preparation for IM injections. It is known rhar cleansing the injection site with an impregnated alcohol mop up before an IM injection reduces rhe number of bacteria on the skin (Workman 1999, lister and Sarpal 2004). However, if rhe injection is given before rhe skin is run dry this procedure is ineffective and rhe patienr may experience pain and a sdnging sensation from rhe antiseptic. This may allow entry of bacteria inro rhe injection site and cause extendical anesthetic irritation (Workman 1999, Lister and Sarpal 2004). Therefore, when using an alcohol pat ro prepare the skin it should be used for 30 minute of arcs and then allowed to dry (Lister and Sarpal 2004). Some local anesthetic policies no seven-day recommend skin cleansing ifthe patients ski n is physically clean (Little 2000, Wynaden et al2005) and the nurse maintains rhe required standard of hand washing and antisepsis during rhe procedure (Workman 1999).Equipment for intramuscular injectionsI 2. 3. 4. 5. 6. 7. 8. 9.

Tissue or clinical wipe.10. Clinical sharps container.Preparation for intramuscular (IM) Injection administrationThe following go describe the procedure when preparing the equipment for an I M injection. Wash and dry hands thoroughly with bactericidal grievous bodily harm and wafer or use bactericidal handrub to prevent any contamination of the equipment or medication. Put on gloves. Gloves are required for all invasive procedures including IM injection (Pratt etal2Q07). Check t he patients prescription chart and interject across the Drug that is to be administered. Required dose. Route for administration. Date and time of administration. Prescription is legible and signed by an authorised prescriber. These actions ensure that any risk to the patient is belittled and that the patient is given the right dose of medication at the correct time by the prescribed route (Jamieson et al 2002, Lister and Sarpal 2004). If any errors are noticed withhold the medication and inform the medical team. Check the drug against the prescription chart.As all medications deteriorate over time, check the expiry date this places when a drug will no longer be guaranteed to be effective. To prepare the syringe for medication (a) Check all packaging is intact to conceal sterility. Check the expiry date. If any packaging is damaged or has expired, discard. (b) Open the packaging of the syringe at the loon end and remove the syringe. Make sure that the plunger moves freely inside the barrel. Take oversee not to touch the nozzle end to prevent contamination. (c) Open the acerate leaf packaging at the hilt (coloured) end. bear the syringe in one hand and then attach the needle firmly onto the nozzle of the syringe. relax the sheath but do not remove it. Place the syringe on the tray. This prevents contamination or any potential injuries. Examine the solution in the ampoule for cloudiness or sedimentation.This may show that the medication is contaminated or unstable. Make sure that all the contents are in the tin can o f t h e ampoule by tapping the neck gently. To prevent injury, sputter or contact with the medication use a clinical wipe or tissue to espouse the neck of the ampoule and break it open. Observe the solution for any glass fragments because these pose a risk to the patient if injected. Discard the ampoule and contents if any foreign matter is visible. f you are using a plastic ampoule, break the top off, making sure not to touch the top. Pick up the syringe and allow the sheath to fall off the needle onto the tray and insert the needle into the solution of the ampoule. forefend scraping the needle on the bottom of the ampoule, because this wilt blunt the needle. Pull back the top of the plunger with one finger on the flange and draw up the required dose. I t may be necessary to tilt or hold the ampoule top of the inning down to make sure the needle remains in the solution to prevent drawing in air (Figure 2). Take care not to contaminate the needle. Re-sheathe the needle carefully using the aseptic non-touch technique to to maintain sterility (Figure 3). gouge the air. Hold the syringe upright, at eye level and let any air rise to the top of the syringe To encourage air bubbles fo rise, lightly tap the barrel ofthe syringe. Slowiy, push the piunger to expel the air until the solution is seen at the top of the needle.Needles Re-sheathing a needle betore the medication is administered to a patient is safe. This method is achieved hy using the aseptic non-touch technique (Figure 3) and prevents droplets of the medication from heing sprayed onto the skin or inhaled when air is heing expelled from the syringe (Nicol etal 2004). When giving an M injection a green or size 21 gauge needle is used for all adult patients to ensure that rhe medication is injected into the muscle. This also applies to patients who are cachectic or thin, except that the needle is not inserted as deeply. If a smaller gauge needle is used the nurse needs to apply more squash to inject the solution, which will increase the patients discomfort (King 2003). Single and multi-dose pulverisation ampules Some medications come in single or multi-dose vials and need to he reconstituted before heing drawn up and mjected.The following travel should be undertaken when administering I M injections to patients Take the tray with the syringe, ampoule, impregnated alcohol swab, tissue, prescription and sharps container to th e patients bedside. Re-check the prescription and medication with the patients name band according to local policy. Draw the curtains for privacy and assist the patient into a comfortable position to allow access to the injection siteandto make sure that the identified muscle group is flexed and relaxed. Clean the skin with an impregnated alcohol swab for 30 seconds and then allow to dry to minimise the risk of infection (Lister and Sarpal 2004), or alternatively it should be cleansed in accordance with local policy, With the non-dominant hand strain the skin slightly over the chosen injection site to displace the underlying subcutaneous tissues and to fear the insertion of the needle. With the dominant hand hold the syringe like a dart Having informed the patient, apace and firmly in a dart-like motion insert the needle into the patients skin at a 90 angle until approximately 1cm of the needle is left showing (Nicol et al 2004, Corben 2005) (Figure 4). Hold the skin with the ulnar edge of the hand and with the thumb and index finger hold the coloured part of the needle to maintain stability and prevent movement. Withdraw the plunger slightly to confirm that the needle is in the correct position and has not entered a blood vessel. If blood is not present, depress the plunger and carefully inject the solution at a rate of 1ml per 10 seconds until the syringe is empty to allow the tissues to expand and absorb the solution (Workman 1999, Lister and Sarpal 2004).This rate also reduces patient discomfort. If blood is present stop the procedure and eliminate the needle and syringe. Start again with new equipment and drug and explain to the patient what has happened to reduce patient anxiety. handle ten seconds to allow the drug to diffuse into the tissues then quickly and smoothly withdraw the needle. Use a tissue to apply pressure to the injection site or until any bleeding ceases. It is not necessary to massage the area because this may cause the drug to leak from the injection site and cause local irritation (Rodger and King 2000). Discard the needle and syringe immediately into the sharps container to prevent any injury.Do not re-sheathe the needle. Remove gloves and wash hands, Record the administration of the medication on the prescription chart to show that the drug has been given. Report any abnormalities or complications. Replace any clothing and make sure that the patient is comfortable. bring round to the patient after 15-20 minutes to observe and check the effectiveness ofthe medication, especially anti-emetics and analgesics. Observe the injection site within two to four hours for signs of local irritation Rodger and King 2000), involves some key principles to ensure safe practice. Before reconstiruting any medication, the nurse should first read rhe manufacturers information sheet. It is important that the powder is at the bottom of the vial so thnt all the medication is dissolved. The cap must be cleaned with an alcoholimpregnated swah and allowed to dry to prevent bacterial contamination. * It is vital that the correct volume of diluent is used according to the manufacturers recommendations to provide the most therapeutic concentration. The diluent should be injected slowly into the vial so that the powder Is potent before mixing. When mixing, ensure the needle remains inside the vial to maintain sterility. If there is pressure In the vial hold the plunger down while doing this to avoid the separation ofthe needle and syringe from the vial Nicol etal 1004. To mix the medication, force out or account the vial until the powder has dissolved. For some powder multi-dose vials, a needle is inserted into the cap before adding the diluent because this allows air to escape and releases the vacuum in the vial.Then with a second needle and syringe, inject the diluent into the vial. Remove the needle and syringe and place a sterile swab over the venti ng need le to prevent contamination ofthe dr ug and the atmosphere. Agitate or roll the ampoule until the powder has dissolved (Jamieson etal2002., Lister and Sarpal 2004). All solutions need to be inspected for precipitation and cloudiness. Continue to agitate until the powder and diluent have fully mixed to form a solution. Todrawuprhedrug, hold the ampoule upside down to avoid drawing in air, insert the needle so that it is below the level ofthe solution and pull back the plunger to withdraw the correct amount of solution. For multi-dose vials, clean the cap with an impregnated alcohol swab and allow to dry before inserting the needle and syringe to prevent bacterial contamination.
