Saline solution load test may help detect traumatic arthrotomy in pediatric patients

Among pediatric patients, the saline solution load test was a reasonable option for the detection of traumatic arthrotomy, according to researchers’ findings.
The researchers performed a saline solution load test among 87 pediatric patients who were undergoing elective knee arthroscopy using a 5-mm superolateral portal as the arthrotomy site, with injection of the saline solution into the lateral aspect of the knee. The researchers identified the 50th, 75th, 90th and 95th percentiles of saline solution load volume required for a positive result and used univariate linear regression to identify a possible relationship between demographics and load volume.

Results showed saline solution load volumes were 27 mL at the 50th percentile, 37 mL at the 75th percentile, 47 mL at the 90th percentile and 58 mL at the 95th percentile. Although mean load volume did not significantly differ between male and female patients, the researchers found load volume significantly correlated with age, height, weight and BMI. The saline solution volume required for a positive test increased as age, height, weight and BMI increased. Specifically, patient height had the highest correlation with volume for a positive saline solution load test, according to study results. – by Casey Tingle
