Trial Outcomes & Findings for Study of Catheter-related Infections Using Antibiotic-coated Versus Conventional Catheters in Children (NCT NCT00370149)

NCT ID: NCT00370149

Last Updated: 2016-02-24

Results Overview

Rates of CRBSI defined as 1. micro-organism isolated from a blood culture; 2. Clinical manifestations of infection such as fever (≥38 C) and/or hypotension (defined according to age-related practice guidelines for systolic blood pressure); 3. No apparent source for the bloodstream infection except for the catheter.

Participant Flow

Participants were recruited and consented during pre-operative visits at Riley Hospital between September 2006 and May 2010. Study catheters were assigned a random identification number by Cook Critical Care, Bloomington, IN. The clinical and infection control teams were blinded to which arm a patient was assigned.

Patients \<18 years of age who had cardiovascular surgery with a case complexity warranting a central venous catheter received either an antibiotic impregnated catheter or a conventional non-impregnated catheter on a randomized, blinded 1:1 ratio.

Antibiotic Impregnated Catheters (M/R)
Randomization to the 2 arms of the study were on a blinded a 1:1 allocation. Patients randomized to M/R had the catheter impregnated with minocycline and rifampin (M/R) inserted intraoperatively. The specific Central Venous Catheters are the Cook Incorporated Spectrum Double Lumen Polyurethane Central Venous Catheters, 4 Fr., 8 cm long, (C-UDLM-401J-ABRM), 5 Fr., 8 cm long, (C-UDLM-501J-ABRM-HC), and 5 Fr., 12 cm long, (C-UDLMY-501J-RSC-ABRM).
Conventional Non-impregnated Catheters (C/S)
Randomization to 2 arms of the study were on a blinded a 1:1 allocation. Patients randomized to this arm had the conventional Central Venous Catheter (C/S) with no antibiotic coating inserted intraoperatively. The specific catheters are the Cook Incorporated Double Lumen Polyurethane Central Venous Catheters, 4 Fr., 8 cm long, (C-UDLM-401J), 5 Fr., 8 cm long, (C-UDLM-501J), and 5 Fr., 12 cm long, (C-UDLM-501J-RSC).

n=165 Participants
Patients randomized to this arm had the M/R inserted intra-operatively as determined by the blinded randomization procedure (1M/R: 1C/S). The catheters were sized to accommodate children in different size ranges: Cook Incorporated Spectrum Double Lumen Polyurethane Central Venous Catheters, 4 Fr., 8 cm long, (C-UDLM-401J-ABRM) and C-UDLM-401J-ABRM-HC), 5 Fr., 8 cm long, (C-UDLM-501J-ABRM-HC), and 5 Fr., 12 cm long, (C-UDLMY-501J-RSC-ABRM-HC).
Conventional Non-impregnated Catheters (C/S)
n=161 Participants
Patients randomized to this arm had the C/S inserted intra-operatively as determined by the blinded randomization procedure (1M/R: 1 C/S). The catheters were one of two sizes to accommodate children in different size ranges: Cook Incorporated Double Lumen Polyurethane Central Venous Catheters,4 Fr., 8 cm long, (C-UDLM-401J), 5 Fr., 8 cm long, (C-UDLM-501J), or 5 Fr., 12 cm long, (C-UDLM-501J RSC).

Randomization to the 2 arms of the study were on a blinded a 1:1 allocation with the objective of determining if a therapeutic difference existed between M/R and C/S catheters. Patients randomized to this Arm had the M/R catheter inserted intra-operatively. Patients receiving this Catheter were enrolled in the study. The specific CVCs are the Cook Incorporated Spectrum Double Lumen Polyurethane Central Venous Catheters, 4 Fr., 8 cm long, (C-UDLM-401J-ABRM), 5 Fr., 8 cm long, (C-UDLM-501J-ABRM-HC), and 5 Fr., 12 cm long, (C-UDLMY-501J-RSC-ABRM-HC).
