Duke anesthesiologists have found that a "Doppler" technique of using reflected sound waves to measure the heart?s pumping action can better guide the administration of fluids and plasma during major surgery. They have found that the use of Doppler technology appears to reduce hospital stays and to speed patient recovery.
Additionally, according to Duke University Medical Center researchers, these patients experience less postoperative nausea and vomiting and are able to eat solid foods much earlier. The researchers say that by not allowing fluid levels to drop below normal -- which is common during surgery -- the proper functioning of the intestines are maintained and recovery is improved.
Typically, fluids such as blood, plasma or synthetic agents known as plasma expanders are administered to patients during surgery to compensate for blood loss and to maintain blood pressure. Physicians add these fluids in response to changes in blood pressure, urine output or heart rate. Instead of this reactive approach, the Duke researchers proactively used an esophageal Doppler monitor (EDM) to obtain continuous readings of cardiac output.

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
