Using cable ties to connect thoracostomy tubes to drainage devices decreases frequency of unplanned disconnection

Abstract

Objectives

Thoracostomy tube (TT) connection to drainage device (DD) may be unintentionally disconnected, potentiating complications. Tape may strengthen this connection despite minimal data informing optimal practice. Our goal was to analyze the utility of cable ties for TT to DD connection.

Methods

On April 1, 2015, our trauma center supplanted use of tape or nothing with cable ties for securing TT to DD connection. We abstracted trauma registry patients with TTs placed from March 1, 2014 to May 31, 2016 and dichotomized as prior (“BEFORE”) and subsequent (“AFTER”) to the cable tie practice pattern change. We analyzed demographics, TT-specific details and outcomes. Primary outcome was TT to DD disconnection. Secondary outcomes included TT dislodgement from the chest, complications, length of stay (LOS), mortality, number of TTs placed and TT days.

Results

121 (83.4% of abstracted) patients were analyzed. Demographics, indications for TT and operative rate were similar for BEFORE and AFTER cohorts. ISS was lower BEFORE (14.12 ± 2.35 vs 18.21 ± 2.71, p = 0.022); however, RTS and AIS for chest were similar (p = 0.155 and 0.409, respectively). TT to DD disconnections per TT days were significantly higher in the BEFORE cohort [6 (2.8%) vs. 1 (0.19%), p = 0.003], and dislodgements were statistically similar [0 vs 3 (0.57%), p = 0.36]. LOS, initial TTs placed and days per TT were similar, and median and mode of days per TT were the same.

Conclusions

Cable ties secure connections between TT and DDs with higher fidelity compared to tape or nothing but may increase rates of TT dislodgement from the chest.
