Abstract/Text
INTRODUCTION: Our study aims to compare the anterior and lateral approaches for needle thoracostomy (NT) and determine the adequacy of catheter lengths used for NT in Asian trauma patients based on computed tomography chest wall measurements.
METHODOLOGY: A retrospective review of chest computed tomography scans of 583 Singaporean trauma patients during period of 2011-2015 was conducted. Four measurements of chest wall thickness (CWT) were taken at the second intercostal space, midclavicular line and fifth intercostal space, midaxillary line bilaterally. Measurements were from the superficial skin layer of the chest wall to the pleural space. Successful NT was defined radiologically as CWT ≤ 5 cm.
RESULTS: There were 593 eligible subjects. Mean age was 49.1 years (49.1 ± 21.0). Majority were males (77.0%) and Chinese (70.2%). Mean CWT for the anterior approach was 4.04 cm (CI 3.19-4.68) on the left and 3.92 cm (CI 3.17-4.63) on the right. Mean CWT for the lateral approach was 3.52 cm (CI 2.52-4.36) on the left, and 3.62 cm (CI 3.65-4.48) on the right. Mean CWT was shorter in the lateral approach by 0.52 cm on the left and 0.30 cm on the right (p = 0.001). With a 5.0 cm catheter in the anterior approach, 925 out of 1186 sites (78.8%) will have adequate NT as compared to 98.2% with a 7.0 cm catheter. Similarly, in the lateral approach 1046 out of 1186 (88.2%) will have adequate NT as compared to 98.5% with a 7.0 cm catheter. Obese subjects had significantly higher mean CWT in both approaches (p = 0.001). There was moderate correlation between BMI and CWT in the anterior approach, r 2 = 0.529 as compared to the lateral approach, r 2 = 0.244.
CONCLUSION: Needle decompression using the lateral approach or a longer catheter is more likely to succeed in Asian trauma patients. A high BMI is an independent predictor of failure of NT, especially for the anterior as compared to lateral approach.
