Abstract

BACKGROUND: Repeat cardiac surgery represents eight to twenty five percent of cardiac surgical procedures. Catastrophic hemorrhage is a known complication of repeat sternotomy. A number of techniques have been described to reduce the incidence of injury to the heart and mediastinal structures during reoperation. This paper reports a new endoscopic technique to visualize and lyse the adhesions between the sternum and heart prior to repeat median sternotomy. METHODS: A unique substernal retractor and endoscopic visualization system was developed specifically to facilitate safe and rapid sternotomy in reoperative cardiac cases. Twenty-four patients underwent elective reoperation using the Endoscopic Redo Sternotomy Retractor and instrumentation. There were 5 patients with prior valve surgery and 19 patients with coronary bypass grafts in place. Retrosternal adhesions were divided with special endoscopic cautery or scissors after which a standard reciprocating saw was used to open the sternum without damage to underlying structures. RESULTS: The time required for endoscopic dissection of retrosternal adhesions ranged from 6 to 22 minutes. No injury to any cardiac structure or conduit occurred. CONCLUSIONS: The Endoscopic Redo Sternotomy Retractor provides excellent visualization of all retrosternal structures and adhesions allowing safe and meticulous dissection prior to sternal opening.

A conductive polymeric material used for nanospray needle and low-flow sheathless electrospray ionization applications.

A conductive polypropylene/graphite mixture is used for the production of polymeric nanospray needle emitters and as a coating on fused-silica capillaries that are used for sheathless electrospray ionization (ESI). The described production of these polymeric nanospray needle emitters and sheathless ESI contacts is exceptionally easy and at a very low cost. The described polymeric nanospray emitters have shown excellent features regarding their chemical inertness and spray performance. The long-term stability of the nanospray needles exceeds 24 h of continuous use. Furthermore, the resistance to electrical discharges, which is one of the factors that often limits the lifetime of metal coated tips, has proven to be outstanding. A voltage of up to 5 kV could be applied without loss of spray performance. The use of polypropylene emitters offers a number of desirable features, as compared to silica based emitters. Among these features are mechanical flexibility and simplified regeneration of the nanospray needle. Continuous nanospray of peptides and proteins in conjunction with orthogonal time-of-flight mass spectrometry are shown with signal relative standard deviations of 5%. In addition, the polypropylene/graphite mixture has also been applied as the conductive contact for sheathless ESI in fast capillary electrophoresis separations.

Rapid microfluidic mixing.

A preformed T-microchannel imprinted in polycarbonate was postmodified with a pulsed UV excimer laser (KrF, 248 nm) to create a series of slanted wells at the junction. The presence of the wells leads to a high degree of lateral transport within the channel and rapid mixing of two confluent streams undergoing electroosmotic flow. Several mixer designs were fabricated and investigated. All designs were relatively successful at low flow rates (0.06 cm/s, > or = 75% mixing), but had varying degrees of success at high flow rates (0.81 cm/s, 45-80% mixing). For example, one design operating at high flow rates was able to split an incoming fluorescent stream into two streams of varying concentrations depending on the number of slanted wells present. The final mixer design was able to overcome stream splitting at high flow rates, and it was shown that the two incoming streams were 80% mixed within 443 microm of the T-junction for a flow rate of 0.81 cm/s. Without the presence of the mixer and at the same high flow rate, a channel length of 2.3 cm would be required to achieve the same extent of mixing when relying upon molecular diffusion entirely, while 6.9 cm would be required for 99% mixing.

Challenges of short magnet design.

The desire to improve patient comfort and acceptance of high field magnetic resonance imaging (MRI) systems results in new approaches to magnet and other critical MRI component design. One such approach, based upon an anatomical field of view analysis, is presented in this paper. The approach is utilized to define imaging volume requirements for short, high field, solenoid magnet designs that maintain whole body imaging capability. A short magnet design with excellent magnetic field homogeneity is presented accordingly. Combined with a novel flared gradient coil the overall system achieves improvements in openness.
