Ultrasound Guided Rhomboid Intercostal Block for Myofascial Pain Syndrome

Rhomboid intercostal block (RIB) is an interfacial plane block described in 2016. It creates analgesia at T2-T9 levels in the hemithorax by applying local anesthetic to the fascia between the rhomboid muscle and the intercostal muscle. It has been used effectively in patients with chronic pain. Recently published report has shown that rhomboid intercostal block (RIB) may provide effective pain control for myofascial pain syndrome (MPS), too. MPS is a regional pain syndrome characterized by trigger points detected in one or more regional muscle groups. The investigators planned a prospective observational study, a total of 30 patients who will apply to our clinic with MPS, will register in research. The investigators will perform ultrasound-guided RIB, and evaluate the clinical outcomes.

About this study

Myofascial pain syndrome (MPS) is the most common cause of musculoskeletal pain and its prevalence in the population is reported to be 21-30%. Rhomboid intercostal block (RIB) is an interfacial plane block described in 2016. It creates analgesia at T2-T9 levels in the hemithorax by applying local anesthetic to the fascia between the rhomboid muscle and the intercostal muscle. It has been used effectively in patients with chronic pain. The investigators planned a prospective observational study.From february to march 10 2021, a total of 30 patients who will apply to our clinic with MPS, will register in research. The investigators will perform ultrasound-guided RIB, and evaluate the clinical outcome Ultrasound guided RIB will applied with linear probe, in plane technique. Block needle was inserted to plane between the rhomboid muscle and intercostal muscles over the T5-6 ribs 2 cm to 3 cm medially from the medial border of the scapula. 13ml of bupivacaine 0.25% and 8mg dexamethasone mixture will inject into the fascial plane. Numerical Rating Scale (NRS) will recorded before and after the block at 30 minutes, day 1, 1-2-4-6 weeks.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Complaint of myofascial pain
Pain that is rated at least 3 on a numerical rating scale (NRS, 0 = no pain, 10 = the worst pain)

Exclusion criteria

pregnancy
the presence of coagulopathy, or the use of anticoagulants
a history of surgery on the block area
allergic to bupivacaine
decline to participate

Treatment and study plan

ultrasound guided rhomboid intercostal block

Other

A linear ultrasound probe was medially placed in the sagittal plane on the medial border of the scapula at the T5-T7 level. We inserted a 22-gauge needle into the fascial plane between the rhomboid major and intercostal muscles in a craniocaudal direction and injected 15 ml mixture of 0.25% bupivacaine with 8 mg of dexamethasone into the fascial plane.

Primary outcomes

Numerical Rating Scale (NRS) Pain Score Change

Time frame: Change from baseline to minutes 30, day 1, week 1, 2, 4, 6 after the block

The 11-point NRS consists of numbers between 0 and 10 where 0 indicates "no pain" and 10 indicates "maximum pain." The patient is instructed to identify one number between 0 and 10, which is best representative of their pain intensity.
