![]() 5, 8 For smaller adults or those with less muscle mass, the volume injected may need to be adjusted. For a well-developed adult, no more than 3 ml of medication should be administered in a single IM injection because the muscle tissue does not absorb it well in larger volumes. Muscle tissue is less sensitive than subcutaneous tissue to irritating and viscous medications. 2, 5 The recommended route and site for each vaccine are included in the manufacturer’s instructions for use. 9 The vastus lateralis and deltoid muscles are the only two sites recommended for vaccine administration because these sites do not contain large vessels that are within reach of the needle. More research is needed to investigate the practice of aspiration before administering an IM injection with medications other than vaccines. 2 For all other medications, there is no evidence to either support or abandon the practice of aspiration before administration. 5Īspiration before injection and slow injection of the medication are not supported by research for vaccine administration. When possible, IM injections should be avoided in muscles that are emaciated or atrophied because these muscles absorb medication poorly. 2 IM injection sites should also be rotated to decrease the risk for hypertrophy. IM injections should be administered so that the needle is perpendicular to the patient’s body or as close to a 90-degree angle as possible ( Figure 1). 2, 7 The needle must be long enough to reach the muscle tissue but not too long to present the risk of hitting underlying neurovascular structures or bone. undefined#ref2">2 The appropriate needle length is determined by the patient’s size, age, and the amount of adipose tissue in the chosen injection site. Any factor that interferes with local tissue blood flow affects the rate and extent of drug absorption.Īn IM injection may require a long, large-gauge needle to penetrate deep muscle tissue. This rich blood supply, however, increases the risk for injecting medication directly into blood vessels. The IM injection route deposits medication into deep muscle tissue, which has a rich blood supply, allowing medication to be absorbed faster than it would be by the subcutaneous route. Take steps to eliminate interruptions and distractions during medication preparation. Consider contacting the practitioner for an alternative, preferred route of medication administration. This route of medication injection is used as a last resort. Intramuscular (IM) injections have been associated with adverse reactions and pain. ![]() Previous failure to do so led to a very painful shot for me, as I injected too far back.Medication Administration: Intramuscular Injection (Home Health Care) - CE ALERT It is important to find the meatiest portion of the muscle, which on me is slightly forward of directly sideways. ![]() The 27g needle is slow though, just a warning. Watch your balance! I have had good luck with 25g 5/8" and 27g 1-1/4" needles. You may want to stretch the skin with your free hand to reduce pain upon needle insertion. I go down slightly from halfway to avoid my pants waistline location to avoid site irritation afterward.Ĥ) Stick it in with the leg relaxed.
