Figure 24-2 Locations of trigger points in the iliocostalis (A) and longissimus (B) muscles and their common referral zones. Trigger point injections (TPIs) refer to the injection of medication directly into trigger points. Other rare, but possible, complications include pneumothorax (when injecting thoracic trigger points), perilymphatic depigmentation, steroid arthropathy, adrenal suppression, and abnormal uterine bleeding. This response is elicited by a sudden change of pressure on the trigger point by needle penetration into the trigger point or by transverse snapping palpation of the trigger point across the direction of the taut band of muscle fibers. Brand names: Decadron, De-Sone LA Six weeks after injection, absence of triggering was documented in 22 of 35 patients in the triamcinolone cohort and in 12 of 32 patients in the dexamethasone cohort. Long term side effects (depending on frequency and dose) include thinning of skin, easy bruising, weight gain, puffiness in the face, higher blood pressure, cataract formation, and osteoporosis (reduced bone density). Understanding Potential Complications Of Epidural Steroid Injections On rare occasions, patients exhibit signs of anesthetic toxicity, including. 2007 Mar;15(3):166-71. doi: 10.5435/00124635-200703000-00006. Most pain is the result of tissue stretching and can be mitigated by injecting slowly. These injections are most useful in instances of joint or tissue injury and inflammation. This study was designed to test the null hypothesis that there is no difference in resolution of triggering 3 months after injection with either a soluble (dexamethasone) or insoluble (triamcinolone) corticosteroid for idiopathic trigger finger. Sometimes it is not safe to use certain medications at the same time. 1362-6. For all intra-articular injections, sterile technique should be used. A third party should witness the patient's signing. Non-sterile gloves can be used when injecting or aspirating soft tissue regions. Needle breakage; avoid by never inserting the needle to its hub. The triamcinolone cohort had significantly better satisfaction and Quinnell grades than did the dexamethasone cohort at the 6-week follow-up but not at the 3-month follow-up. For most injections, 1 percent lidocaine or 0.25 to 0.5 percent bupivacaine is mixed with a corticosteroid preparation. Trigger point injection to the levator ani muscles is a minimally invasive, nonsurgical treatment option for patients who have pelvic floor myofascial spasm and are refractive to physical therapy and medication. 16 Dry needling, a technique that involves multiple advances of a needle into the muscle at the region of the trigger point, provides as much pain relief as an injection of lidocaine. 2008 Sep;67(9):1262-6. doi: 10.1136/ard.2007.073106. Hematoma formation; avoid by applying direct pressure for at least two minutes after injection. Therapeutic indications include the delivery of local anesthetics for pain relief and the delivery of corticosteroids for suppression of inflammation. Dosage. Appropriate timing can minimize complications and allow a clear diagnosis or therapeutic response. I would recommend confirming with the provider that this is the correct medication since there is a very similar medication J1094 - Injection, dexamethasone acetate, 1 mg. The affected area should be rested from strenuous activity for several days after the injection because of the small possibility of local tissue tears secondary to temporarily high concentrations of steroid. Would you like email updates of new search results? They noted that the best responses to injection were found when the local twitch response was provoked by impaling the active point.13. Common and Rare Side Effects for Dexamethasone Sodium Phosphate - WebMD Phys Med Rehab, Nov. 1998, Vol 79(11), pp. St. Louis, Mosby, 2009.). Endogenous opioid release may play a role in TPIs. If therapeutic effect is achieved, a maximum of four injections per year is recommended. Steroids can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have. Increased bleeding tendencies should be explored before injection. Dexamethasone Injection: MedlinePlus Drug Information Trigger Points: Diagnosis and Management | AAFP Each thrust coincided with the injection of 0.02 to 0.05mL of injectate, up to a total of 0.5 to 1mL in each trigger point. A healthcare provider will give you this injection. 2021 Nov;29(4):265-271. doi: 10.1177/2292550320969643. Marcaine is also known as bupivacaine hydrochloride. Therapeutic responses to corticosteroid injections are variable.4 The patient's response to previous injection is important in deciding whether and when to proceed with reinjection. Dexamethasone Sodium Phosphate Injection: Uses, Side Effects - WebMD To minimize pain and inflammation after leaving the office, the patient should be advised to apply ice to the injection site (for no longer than 15 minutes at a time, once or twice per hour), and non-steroidal anti-inflammatory agents may be used, especially for the first 24 to 48 hours. Seigerman D, McEntee RM, Matzon J, Lutsky K, Fletcher D, Rivlin M, Vialonga M, Beredjiklian P. Cureus. Methods: The authors conducted a prospectively collected longitudinal study of trigger finger patients separated into four stages of severity. ; Local Infection - Trigger points should not be performed in the presence of systemic or local infection. The patient should keep the injection site clean and may bathe. Dexamethasone is a synthetic glucocorticoid used in the treatment of inflammatory and immune conditions in children and adults. pain, redness, or irritation at site where injected. Am Fam Physicians 2002; 66(2):283-289 4. Outcomes of Corticosteroid Treatment for Trigger Finger by Stage - LWW Participants were randomly . Roberts JM, Behar BJ, Siddique LM, Brgoch MS, Taylor KF. J Hand Surg Am. Physicians should resist external pressure for a quick return of athletes to playing sports by the use of joint or soft tissue injections. Multiple insertions in different directions from the subcutaneous layer were fast in and fast out to probe for latent trigger points. Abdul et al. Injections of an anesthetic mixture directly into the muscle can help the muscle relax and relieve pain. Epub 2020 Nov 10. Acute trauma or repetitive microtrauma may lead to the development of stress on muscle fibers and the formation of trigger points. Repeated injections in a particular muscle are not recommended if two or three previous attempts have been unsuccessful. Comparison of Different Dosages and Volumes of Triamcinolone in the Treatment of Stenosing Tenosynovitis: A Prospective, Blinded, Randomized Trial. Generic name: dexamethasone (injection) [DEX-a-METH-a-sone] Table 1 lists soft tissue and joint condition indications for diagnostic and therapeutic injections. The injection was given intramuscularly at the point of maximum tenderness, and patients were subsequently evaluated 1 week, 1 month and 3 months after the procedure. Corticosteroid injections also should be avoided in cases of Achilles or patella tendinopathies. MeSH A trigger point injection (TPI) is an outpatient procedure used to treat painful areas of muscle that contain trigger points, or "knots" of muscle that form when muscles do not relax. When clinicians were asked to examine patients with either myofascial pain, fibromyalgia, or healthy controls, the number of tender points identified was generally consistent.43 Even among experts in myofascial pain and fibromyalgia there was inconsistency in the number of taut bands, presence of referred pain, and local twitch responses reported. Tight bands of muscle (trigger points) can be a source of chronic neck pain and they are sometimes injected to manage chronic neck pain. A set of trigger point injections means injections in several trigger points in one sitting. Fine and colleagues reported that the analgesic effects of TPIs could be reversed with intravenous naloxone.60 Mechanical disruption may play some role in breaking up trigger points.38,61 Spontaneous electrical activity, as originally observed, was later confirmed to be end-plate potentials.62 This finding was used to show that many traditional ah-shi acupuncture points corresponded to trigger points.63 Animal models also suggest the role of the autonomic nervous system related to phentolamine, an alpha-adrenergic agonist that inhibits sympathetic activation and decreases spontaneous electrical activity in rabbit myofascial trigger spots.64. Asymptomatic subjects were reported to have as many latent trigger points as those with myofascial pain or fibromyalgia. Few studies have investigated the efficacy or duration of action of the various agents in joints or soft tissue sites. Trigger point injection is one of many modalities utilized in the management of chronic pain. Choice of Corticosteroid Solution and Outcome After Injection for Trigger Finger. Trigger point injection, which is commonly used to treat other pain conditions, has been shown to improve symptoms in women with chronic pelvic pain, with efficacy similar to that of physical. Thus, these two pain syndromes may overlap in symptoms and be difficult to differentiate without a thorough examination by a skilled physician. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective. Compression of the point for 2 minutes allowed hemostasis, which was followed by stretching of the muscle. Clinicians should also inquire about medication history to note prior hypersensitivity/allergy or adverse events (AEs) with drugs similar to those being considered, and evaluate contraindications for these types of drugs. Twenty-five patients requested a second injection (10 triamcinolone arm, 15 dexamethasone arm), and 21 elected operative treatment (10 triamcinolone arm, 11 dexamethasone arm) during the study period. Various substances have been used for trigger point injections, including local anesthetics, botulinum toxin, sterile water, and sterile saline. Antidepressants, neuroleptics, or nonsteroidal anti-inflammatory drugs are often prescribed for these patients.1. This therapeutic approach is one of the most effective treatment options available and is cited repeatedly as a way to achieve the best results.5, Trigger-point injection is indicated for patients who have symptomatic active trigger points that produce a twitch response to pressure and create a pattern of referred pain. Call your doctor at once if you have: worsening pain, swelling, or stiffness of a joint treated with dexamethasone; swelling, rapid weight gain, feeling short of breath; blurred vision, tunnel vision, eye pain, or seeing halos around lights; bloody or tarry stools, coughing up blood; increased pressure inside the skull--severe headaches, ringing in your ears, dizziness, nausea, vision problems, pain behind your eyes; pancreatitis--severe pain in your upper stomach spreading to your back, nausea and vomiting; or. It is not considered medically necessary to repeat injections more frequently than every 7 days. Neuroplastic changes in the dorsal horn may also activate neighboring neurons at lower thresholds, resulting in allodynia, hypersensitivity, and referred pain. Before receiving TPIs, patients should first be assessed for LBP using an evidence-based and goal-oriented approach focused on the patient history and neurologic examination, as discussed in Chapter 3. Trigger points are defined as firm, hyperirritable loci of muscle tissue located within a taut band in which external pressure can cause an involuntary local twitch response termed a jump sign, which in turn provokes referred pain to distant structures.1 Establishing a diagnosis of trigger points often includes a history of regional pain, with muscular overload from sustained contraction in one position or repetitive activity, presence of a taut band with exquisite spot tenderness, reproduction of the patients pain complaint, and a painful limit to muscle stretch.24 Despite being an integral component to the definition of trigger points, it has been reported that the twitch response cannot reliably be established.5, The two main types of trigger points are active and latent. This study prompted some clinicians to abandon the local twitch response to more reliably quantify tenderness with pressure thresholds, as reflected in the most current diagnostic criteria for trigger points.24, Pressure threshold is the minimum pressure that reproduces pain (or tenderness) in a suspected trigger point, and has been claimed to be an objective, reproducible, and reliable method for their detection.48,50,7577 Fischer attempted to establish standard, normal pressure thresholds, which were found to be different for each gender and each muscle.76, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window). TMJ Injection Treatments: Lidocaine, Steroids, Hyaluronate & Botox The site is secure. For diagnostic injections, the procedure should be performed when acute or chronic symptoms are present, when the diagnosis is unclear or needs to be confirmed, when consideration has been given to other diagnostic modalities, and when septic arthritis has been ruled out (by aspiration and fluid analysis). For soft tissue injections, the following modalities may be used for short-term partial anesthesia: applying ice to the skin for five to 10 minutes; applying topical vapo-coolant spray; or firmly pinching the skin for three to four seconds at the injecting site.12 Once the skin is anesthetized, the needle should be inserted through the skin to the site of injection. Many clinicians use injectables that combine short-acting compounds with long-acting suspensions (e.g., betamethasone sodium phosphate and acetate suspension), thereby obtaining the beneficial effects of both types of preparations. Physical Medicine Center Serving Tampa, Florida - Trigger Point Injections However, manual methods are more likely to require several treatments and the benefits may not be as fully apparent for a day or two when compared with injection.10, While relatively few controlled studies on trigger-point injection have been conducted, trigger-point injection and dry needling of trigger points have become widely accepted. A trigger point injection can help soothe myofascial pain, especially in your neck, shoulder, arms, legs and lower back. Trigger-point injection can effectively inactivate trigger points and provide prompt, symptomatic relief. Treatment of Bursitis, Tendinitis, and Trigger Points As with any invasive diagnostic or therapeutic injection procedure, there are absolute and relative contraindications (Table 2).7 Drug allergies, infection, fracture, and tendinous sites at high risk of rupture are absolute contraindications to joint and soft tissue injection. Written by Cerner Multum. Heyworth BE, Lee JH, Kim PD, Lipton CB, Strauch RJ, Rosenwasser MP. A short-acting solution, such as dexamethasone sodium phosphate (Decadron), is less irritating and less likely to cause a postinjection flare than a long-acting dexamethasone suspension. Evidence-Based Management of Low Back Pain. Trigger Point Steroid Injection | Pain Treatment Centers of America - PTCOA After the close of the study, there were 8 recurrences among patients with documented absence of triggering in the triamcinolone cohort and 1 in the dexamethasone cohort. The intensity of pain was rated on a 0 to 10 cm visual analogue scale (VAS) score. Role of Intramuscular Corticosteroids in Trigger Point Injections: A Evidence-based reviews of joint and soft tissue injection procedures have found few studies that support or refute the efficacy of common joint interventions in medical practice.13 However, substantial practice-based experience supports the effectiveness of joint and soft tissue injection for many common problems. If additional tender points are palpable, they should be isolated, needled and injected. On rare occasions, patients exhibit signs of anesthetic toxicity, including flushing, hives, chest or abdominal discomfort, and nausea. TPIs are widely available throughout the United States. Orthopedics 2013; 36(9):e1141-e1148. Time to Improvement After Corticosteroid Injection for Trigger Finger. To preserve autonomy, patients were permitted additional injections and operative treatment at any time. The highest inter- and intra-examiner reliability for locating trigger points was achieved with pressure threshold algometry.48,49 Once trigger points are located and marked with a skin pen, the skin is generally prepared with a standard antibacterial agent such as isopropyl alcohol or betadine solution. There are many other diseases that can be affected by steroid use, and many other medicines that can interact with steroids. The concept of abnormal end-plate potentials was used to justify injection of botulinum toxin to block acetylcholine release in trigger points.57 McPartland has expanded on the idea of excessive acetylcholine by suggesting that congenital or acquired genetic defects in presynaptic, synaptic, or postsynaptic structures may contribute to an individuals susceptibility to myofascial pain.45. Discussion with the patient should include indications, potential risks, complications and side effects, alternatives, and potential outcomes from the injection procedure. However, these injections seldom lead to significant, long-lasting relief. The indications for joint or soft tissue aspiration and injection fall into two categories: diagnostic and therapeutic. Find patient medical information for dexamethasone sodium phosphate injection on WebMD including its uses, side effects and safety, interactions, pictures, warnings and user ratings. The needle should be long enough so that it never has to be inserted all the way to its hub, because the hub is the weakest part of the needle and breakage beneath the skin could occur.6, An injectable solution of 1 percent lidocaine or 1 percent procaine is usually used. For thick subcutaneous muscles such as the gluteus maximus or paraspinal muscles in persons who are not obese, a 21-gauge, 2.0-inch needle is usually necessary.10 A 21-gauge, 2.5-inch needle is required to reach the deepest muscles, such as the gluteus minimus and quadratus lumborum, and is available as a hypodermic needle. The injection should flow easily and should not be uncomfortable to the patient. Many researchers agree that acute trauma or repetitive microtrauma may lead to the development of a trigger point. The indication for TPIs is CLBP with active trigger points in patients who also have myofascial pain syndrome that has failed to respond to analgesics and therapeutic exercise, or when a joint is deemed to be mechanically blocked due to trigger points and is unresponsive to other interventions. Methylprednisolone (Depo-Medrol) is often the agent selected for soft tissue injection. History of pain, local and referred, will provide important clues to the underlying pathology.
