BackgroundFascial plane blocks are a valuable and important aspect of patient care. However, nerve blocks sometimes present with a technical difficulty that can lead to upsetting the operating room schedule, cause discomfort to the patient, or lead to inadequate block. Potential predictors of this difficulty were evaluated.
MethodsIn a single-blind study, ultrasound image quality was evaluated on a grading metric, and its correlation with several factors that could potentially impact the difficulty of a procedure, including age, BMI, weight, length of surgery, IV fluids, and pre-vs postoperative block, was assessed.
ResultsNo correlation was found between any of our anesthetic, patient, or surgical factors, and the resulting image quality.
ConclusionThe study population was limited compared to our initial goals. We found no correlation between studied variables and image quality, but confounding factors that may affect image quality have not been ruled out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
