About this study
Official title: Ultrasound-guided (US) Serratus Anterior Plane Block (SAPB) for Acute Rib Fractures in the Emergency Department (ED)
The purpose of this randomized controlled study is to determine whether the serratus anterior plane block reduces pain more than the usual treatment for rib fractures in the same amount of time.
Read the detailed description
Patients with unilateral rib fractures in the Highland Hospital Emergency Department who agree to participate will be randomized 1:1 to either the control group or the experimental group. Those in the control group will receive the usual oral and/or IV pain medication as needed. The experimental group will receive an ultrasound-guided serratus anterior plane block. Numerical pain rating scale scores at rest and when taking a deep breath will be recorded pre-intervention and at times 0, 20, 40, and 60. At time 60, patients who received the SAPB will receive sensory testing. Patients will be offered additional pain medication as needed at times 20, 40, and 60.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
BupivacaineDrug
Patient will be positioned supine or in the lateral decubitus position on the side contralateral to the fracture(s). A 3.5 in 20-gauge needle, extension tubing, and a 30 mL syringe loaded with 0.25% bupivacaine and 3 mL of 1% lidocaine loaded in a 5 mL syringe with a 27-gauge needle will be prepared. The ribs, teres minor, latissimus dorsi, and serratus anterior will be identified with bedside US and the site of entry marked along the lateral aspect of the 4th-5th rib. The skin will be sterilized and lidocaine placed at the site of entry. The needle will be introduced at a steep angle and advanced in-plane, under US-guidance, to the plane superficial to the serratus anterior muscle. A test dose of normal saline will confirm proper needle tip placement with opening of the intramuscular layer. Injection with aliquots of 3-5 mL after negative aspiration will continue until 30mL of 0.25% bupivacaine are administered.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Numeric Pain Rating Scale score between time 0 and time 60 when comparing block and control groups
Change in Numeric Pain Rating Scale scores between time 0 and time 60 between block and control groups: Numeric Pain Rating Scale score at 0 minutes minus Numeric Pain Rating Scale score at 60 minutes, where a score of 0 is no pain and 10 is the worst pain the patient can imagine.
Measured: 60 minutes
Secondary outcomes (6)
Change in Numeric Pain Rating Scale score at rest versus when taking a deep breath when comparing block and control groups
Change in Numeric Pain Rating Scale score for resting chest pain and dynamic chest pain at 20, 40, and 60 minutes between block and control groups, where a score of 0 is no pain and 10 is the worst pain the patient can imagine.
Measured: 20, 40, 60 minutes
Difference in total morphine equivalents
Difference in total parenteral morphine equivalents received during study period (0 minutes to 60 minutes) and at 4, 12, and 24 hours (unless discharged from the hospital prior to 24 hours) in the block and control groups.
Measured: 1, 4, 12, and 24 hours
Successful analgesia for block group
Successful analgesia at 20, 40 and 60 minutes: Proportion of patients not receiving morphine dosing.
Measured: 20, 40, 60 minutes
Non-opioid medications given (yes/no)
NSAID, APAP, Gabapentin administered in block versus control groups.
Measured: 20, 40, 60 minutes
Adverse events
Proportion of patients with new onset of seizure, arrhythmias, hyper or hypotension (SBP<90 or >180), hypoxia, nausea, lightheadedness, vomiting.
Measured: 60 minutes
Sensory testing
Sensory testing to cold stimulus (alcohol swab) in the block group along the lateral sternal, anterior axillary, and posterior axillary lines at the levels of T2-T10 using a 3-point scale: 0 (unchanged), 1 (reduced), or 2 (no sensation).
Measured: 60 minutes

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Bupivacaine and Fentanyl, morphine, hydromorphone, hydrocodone, acetaminophen, ketorolac, gabapentin, ketamine, ibuprofen in people with Rib Fractures and Rib Fracture Multiple, run by Andrew A Herring at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 19 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Andrew Herring (510-633-7498, aherring@alamedahealthsystem.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Numeric Pain Rating Scale score between time 0 and time 60 when comparing block and control groups (time frame: 60 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2018; AzTrials last refreshed its copy on 6 Nov 2026.
