Safe Zone in Trigger Point Injection
Avoid Pneumothorax: Identification of the Interscapular Area Trigger Point Injection Safe Zone in Different Positions (Sitting/Prone)
Ankara University
211 participants
Oct 1, 2024
OBSERVATIONAL
Conditions
Summary
The goal of this observational study is to define the safe distance that will reduce the risk of pneumothorax through ultrasonographic imaging measurements in both sitting and prone positions to ensure patient safety during these procedures. The main question\[s\] it aims to answer \[is/are\]: The mean distance between the skin and pleura in sitting position during the inhalation and exhalation The mean distance between the skin and pleura in prone position during the inhalation and exhalation
Eligibility
Inclusion Criteria2
- patients diagnosed with Myofascial Pain Syndrome
- patients scheduled for trigger point injections due to Myofascial Pain Syndrome.
Exclusion Criteria6
- under 18 years of age,
- additional diseases other than Myofascial Pain Syndrome,
- the presence of active infection in the interscapular area where ultrasound imaging and measurements will be performed,
- lesions that disrupt skin integrity or affect subcutaneous and muscle structures such as anomalies or masses that could impair imaging quality
- individuals with known lung diseases
- not consent to participate in the study."

Interventions
Volunteers will first be asked to sit on a chair with their back facing the examiner, placing their arms in a relaxed position with their head supported on a surface in front of them. The ultrasound operator will be positioned behind the volunteer. Initially, in the sitting position, volunteers will be asked to maintain normal breathing. Once an optimal ultrasound image is obtained, the image will be frozen, and measurements will be taken from the same image in sequence. The measurements to be performed are as follows: skin-fat tissue distance, skin-trapezius muscle distance, skin-rhomboid muscle distance, skin-rib distance, skin-pleura distance, and rhomboid muscle-pleura distance. These measurements, in millimeters, will be recorded in the data collection form. The same measurements will also be taken during deep inhalation and deep exhalation in the sitting position."
