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.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
