Utility Of Chest Radiographs After Guidewire Exchanges Of Central Venous Catheters., P Frassinelli, Michael D. Pasquale Md, Facs, Fccm, M D Cipolle, M Rhodes

Michael D Pasquale MD, FACS, FCCM

OBJECTIVE: To determine whether chest radiographs are warranted after uncomplicated guidewire exchanges of central venous catheters in patients admitted to a Level I trauma intensive care unit.

DESIGN: Prospective study performed in two phases.

SETTING: Intensive care unit in a Level I trauma center.

PATIENTS: Patients admitted to a Level I trauma center intensive care unit who required central venous catheter guidewire exchanges.

INTERVENTIONS: Criteria for uncomplicated guidewire exchanges were established and followed. A catheter exchange checklist was completed at each procedure, and a chest radiograph was performed after each guidewire exchange. The complications followed were catheter malposition, pneumothorax, hemothorax, …

Outcome Of Blunt Thoracic Aortic Injury In A Level I Trauma Center: An 8-Year Review., E J Frick, M D Cipolle, Michael D. Pasquale Md, Facs, Fccm, T E Wasser, M Rhodes, Raymond L. Singer Md, S A Nastasee

Michael D Pasquale MD, FACS, FCCM

BACKGROUND: The purpose of this study was to evaluate our experience with blunt thoracic aortic injury and identify factors predictive of outcome.

METHODS: Hospital charts, trauma registry data, and autopsies of 64 patients with blunt thoracic aortic injury from 1988 to 1995 were reviewed.

RESULTS: Patients were identified and segregated based on admission physiology. Group 1 patients (n = 19) arrived in arrest. Group 2 patients (n = 10) arrived in shock with systolic BP 90. Group 3 patients (n = 35) arrived with systolic BP>90. All patients in groups 1 and 2 expired. Injury Severity Scores for nonsurvivors …

Cannulation Of The Axillary Artery For Cardiopulmonary Bypass: Safeguards And Pitfalls., Michael C Sinclair, Raymond Singer, Norman J Manley, Ralph M Montesano

Raymond L Singer MD

BACKGROUND: The ascending aorta is the customary site for arterial cannulation for cardiopulmonary bypass. Favorable experience at our institution and elsewhere using axillary artery cannulation in treating type A aortic dissections has caused us to broaden our indications for using this site for arterial cannulation for cardiopulmonary bypass.

METHODS: Medical records, operative notes, and perfusion records were reviewed in all patients in whom the axillary artery was cannulated directly or by a graft for cardiopulmonary bypass from January 1, 2000 through August 30, 2002.

RESULTS: Seventy-five patients underwent axillary artery cannulation during the 32-month interval. Eleven patients had ascending aortic …

A Fully Automated Non-External Marker 4d-Ct Sorting Algorithm Using A Serial Cine Scanning Protocol, Greg Carnes, Stewart Gaede, Edward Yu, Jake Van Dyk, Jerry Battista, Ting-Yim Lee

Edward Yu

Current 4D-CT methods require external marker data to retrospectively sort image data and generate CT volumes. In this work we develop an automated 4D-CT sorting algorithm that performs without the aid of data collected from an external respiratory surrogate. The sorting algorithm requires an overlapping cine scan protocol. The overlapping protocol provides a spatial link between couch positions. Beginning with a starting scan position, images from the adjacent scan position (which spatial match the starting scan position) are selected by maximizing the normalized cross correlation (NCC) of the images at the overlapping slice position. The process was continued by 'daisy …
