  • Staple Usage Comparison Between Suction Calibration System and Rubber Bougie in LSG

    Elizabeth Dovec, MD, Medical Director, GBMC Comprehensive Obesity Management Program

    Data suggests a savings of 0.33 staple load per laparoscopic sleeve gastrectomy (LSG) procedure after switching to a suction calibration system (SCS). That translates to saving a staple approximately every third case. With bariatric staple loads costing upwards of over $400 per staple, this could mean significant savings for institutions that implement a SCS in their LSG procedures.

  • An Evidence Based Approach to Determining Hospital Suction Canister Change Protocols

    Keith S. Kaye, MD, MPH; Dror Marchaim, MD; Lauren Bentley, MS

    Presented at the 37th Annual Meeting of the Association for Professionals in Infection Control and Epidemiology (APIC 2010).

    The contemporary literature review does not substantiate the Q24hr recommendation. In vitro work performed shows that a significant risk to the patient exists at 24hrs. Survey results showed that although 93% of facilities have a canister change protocol, only 53% of them change the canister on a Q24hr basis. We suggest that more evidence needs to be obtained for generating canister change protocols. Also, facilities should study their suction circuits to identify any associated risk.

  • Clinical Importance of Unrestricted Flow in Hospital Suction Systems

    Michael J. Neary, MD;  John J. Hill, BA, RRT-NPS; Bonita Weyrauch, RN, CWS, DNC, CCT; Kevin Klocek, EMT, BSBME, MBA; Randolph Cremer, CBET

    Clinical White Paper published by Boehringer Laboratories August 2008

    Hospital suction outlets need to provide a minimum of 85 liters per minute of unrestricted airflow to be compliant with established standards. Suction regulators attached to the wall outlets restrict the flow available from these outlets. Only Boehringer suction regulators minimally affect the available flow and deliver maximum suction power, ensuring the most significant ability to remove patient secretions at any suction setting.

  • Healthcare Product Comparison System Report on Suction Regulators

    (Note the HPCS report is not an evaluation. The information it contains is not the result of testing by ECRI Institute’s clinical and engineering personnel. Although this information is obtained from reliable sources, ECRI Institute cannot guarantee its accuracy.)

    This Product Comparison covers low-volume, surgical, thoracic, and tracheal suction regulators that dynamically control the selected vacuum level, responding to changes in flow conditions that may be introduced during suctioning procedures. Adapters that convert continuous regulators to intermittent regulators are also covered. Other regulators, such as those controlled with a bleeder valve that does not dynamically control vacuum levels, are omitted. In addition, any accessories associated with suction regulators are excluded; however, compatible inlet and outlet fittings are listed in the chart.

  • Reducing the HAI Risk Attributable to Hospital Suction Canisters: An Evidence Based Approach

    Michael J. Scala, RN, BSN, EMT-P

    Clinical White Paper Published in 2011 

    Suction collection canisters are used in almost every patient care area. They form a reservoir where solid and liquid components are separated from air and aerosols. Once these collection vessels have been employed clinically, they become an environmental reservoir of pathogens in that patient care area. Ventilator-Associated Pneumonia (VAP) bundles commonly include the recommendation that collection canisters be changed at a minimum of Q24hrs. This literature review will attempt to demonstrate an evidence-based canister change protocol supportive of the reduction of this potential HAI vector. This evidence-based protocol recommendation could represent over $1000 worth of savings per ICU bed per year.

  • Suction Regulators: A Potential Vector for Hospital-Acquired Pathogens

    Keith S. Kaye, MD, MPH; Dror Marchaim, MD; Chester Smialowicz, MD; Lauren Bentley, MSBME

    Infection Control and Hospital Epidemiology 2010, 31(7), 772-774.

    The role of suction regulators in nosocomial infections has, to our knowledge, not been studied. A sampling of devices used in hospitals was conducted. Many regulators (173 [37%] of 470) were found to be colonized. A suction circuit model revealed that pathogens can disseminate throughout the circuit (retrograde and antegrade), colonizing an experimental patient’s stomach.

  • The Efficacy of Backflushing Suction Regulators as a Method of Internal Disinfection

    John J. Hill, BA, RRT-NPS, Director Respiratory Care Services; Michael J. Neary, MD, Director MICU/SICU, Associate Medical Director Respiratory Care Services; Caroline Panichello, CRT/RPFT, Respiratory Care Staff; Deborah Heart and Lung Center, Browns Mills, NJ, USA

    Presented at the 55th Annual International Respiratory Conference (AARC 2009).

    This study demonstrated that manufacturer-recommended backflushing does not adequately disinfect internal suction regulator passages. The novel approach to device sterilization offered by the Boehringer Regulator, wherein traditional, well-accepted autoclave techniques are employed to optimize device disinfection, would appear to offer a substantial clinical advantage in the prevention of nosocomial infections.

  • Use of Filters on Medical Gas System Outlets and Vacuum System Inlets

    User Experience Network™ [Health Devices Dec 1994;23(12):494-5]

    Recommendations include routinely inspect and maintain medical gas and vacuum systems, use filters on medical gas outlets only as a temporary measure to protect patients and devices against particles, bacteria, or liquid water found in the system, use suction canisters for any suctioning procedure, and use smoke evacuators instead of the central vacuum system for smoke evacuation during most procedures. Note that filters will not remove water vapor or other gases, which can damage some medical devices.
