Abstract

Abstract: Objective: To compare the maximum force and displacement to failure of 4 different types of thoracostomy tube connecting devices. Study Design: Experimental in vitro study. Study Population : Four types of thoracostomy tube connecting devices (n = 10 each). Methods: Four different connecting device configurations (10 constructs each) were tested by maximum distraction to failure using a dynamometer: (1) CTTWW—a 3‐way connector with a male luer slip attached to a thoracostomy tube by a Christmas tree adapter and secured to the tube with 21 gauge orthopedic wire; (2) CTTWRCW—a 3‐way connector with a male luer lock with a rotating collar attached to a tube by a Christmas tree adapter and secured to the tube with 21 gauge orthopedic wire; (3) LVSBC—a Lopez valve attached to a tube with its short‐barbed connector; and (4) LVLBC—a Lopez valve attached to a tube with its long‐barbed connector. Results: The maximum distraction force to failure was significantly greater for CTTWRCW (250.9 N; range 143.7‐293.6) than CTTWW (132.9 N; range 84.2‐224.1), LVLBC (90.8 N; range 74.0‐123.4), and LVSBC (54.6 N; range 39.6‐164.2). The median displacement to failure of CTTWRCW (150 mm; range 54‐190) was significantly longer than that of CTTWW (34.5 mm; range 22‐70), LVLBC (32.5 mm; range 24‐57), and LVSBC (16 mm; range 11‐69). Conclusion: The CTTWRCW group required greater force to create failure and had a longer displacement to failure, making it a more secure choice for connection to thoracostomy tubes.
