Peripheral arterial cannulation is a necessity for installation of cardiopulmonary bypass in minimally invasive cardiac surgery (MICS). In the vast majority of cases, the femoral artery is the preferred arterial cannulation site. Distal limb hypoperfusion and ischemia can occur in the cannulated limb since antegrade perfusion is not routinely provided. Furthermore, the diameter of the cannula required to maintain adequate cardiopulmonary bypass (CPB) flow is often approaching that of the patient's femoral artery diameter, compromising distal blood flow. The possibility of distal limb ischemia is often raised as a criticism to peripheral cannulation for cardiopulmonary bypass and by extent to minimally invasive cardiac surgery. Ischemia of the lower limb is of high incidence in patients undergoing extracorporeal membrane oxygenation (ECMO) therapy, in which the same femoral cannulation technique is used. Therefore this complication has extensively been described in ECMO literature. However, no clinical trials have been performed in patients undergoing MICS, despite the same cannulation and perfusion route. ECMO patients often differ from MICS patients in morbidity as well as in duration of cannulation. Up to now, one could not observe any clinical sequelae of limb ischemia in MICS patients but a formal study of distal leg perfusion in MICS is recommended to screen its safety and to identify possible risk factors.
1. Primary Objective: Demonstrate that the IC-Flow Imaging device with Indocyanine Green (ICG) is a feasible technique when visualizing and identifying perfusion of organs when compared to The KARL STORZ VITOM II ICG System during open reconstructive surgical procedures 2. Secondary Objective: 1. Evaluate the mean Assessment of handling properties using The IC- Flow versus The VITOM II. 2. Evaluate the mean Surgeon preference Level using The IC- Flow tower, The IC-Flow Hand-held device versus The VITOM II.
This study is an open label trial designed to test the effectiveness of the Tennant Biomodulator® PRO electrical stimulation device (Avazzia), which uses BEST™ (Bio-Electric Stimulation Technology), on hospital in-patients to improve perfusion in the treated and contralateral limb.
The present study aims to evaluate, with non-invasive methods, the relationships existing between PEEP and renal perfusion in patients undergoing surgery and requiring ventilatory support and monitoring in intensive care. Renal perfusion will be assessed at baseline (PEEP 0), subsequently ,at the application of progressive increases of PEEP. At the end of the measurements, the implications of the use of PEEP on the renal vascular system will be analyzed.
This is a randomized study using a variety of techniques to compare and examine blood flow to the remaining skin after mastectomy. All treatments being used are considered standard of care and are not experimental. The objective is to compare the techniques and the incidence of perfusion related problems in patient's undergoing mastectomy with immediate breast reconstruction.
This study is designed to evaluate the information provided to the clinicians by the surgical imaging device. It is also to gain insight on the user interface and how "user friendly" it is to the clinician.
Low thermal dissection devices have been introduced as a tool to improve surgical outcomes. PlasmaBlade, a low thermal dissection device, has shown to be associated with effective cutting, and significantly lower temperature than traditional electrosurgical dissection device. Thus, low thermal devices would improve flap perfusion by decreasing the thermal injury resulted by the dissection. Looking into the use of low thermal devices in cases of mastectomy and immediate breast reconstruction has not been documented. The aim of this study is to determine if there are clinical flap perfusion, surgical site drainage, and pain scores differences between mastectomy flaps created using low thermal dissection device and those done with the standard care of Bovie cautery in order to warrant a formal study.
This study evaluates the association between near infrared spectroscopy (NIRS) and indexed oxygen delivery (DO2i) and their possible correlation with postoperative organ failure.
Preconditioning of regional skin is known to reduce post surgery complications due to increased perfusion and better skin condition. The aim of this study is to prove that local heating through a standardized device in patients with spinal cord injury induces no burnings or other relevant side effects. The investigators expect an increased regional perfusion, temperature and redness.
