Innovative Gel Reduces Post-Operative Pain Following Endoscopic Sinus Surgery
A gel made from a patients own blood reduces pain and may improve wound healing following endoscopic sinus surgery according to researchers at Rush University Medical Center. The study, published in the September issue of the Annals of Otology, Rhinology and Laryngology, found that patients who received platelet gel reported an easier recovery than patients who received traditional packing to stop bleeding.
The platelet gel is derived from the patients own plasma and is made in the operating room. After a small amount of the patients blood is drawn, it is put into a centrifuge machine that separates out the platelet rich plasma. The fact that the platelet gel is derived from the patients own blood eliminates the risk of acquired diseases possible with other pooled blood products. Following endoscopic surgery, the gel is sprayed into the sinus cavity.
"The gel is rich in wound factors. It contains platelets for clotting, growth hormones for healing, and white cells to fight infection," said Dr. Jay M. Dutton, study co-author and assistant professor of otolaryngology at Rush. "It effectively stops the bleeding and may advance the healing process."
The plasma gel replaces temporary sponges or sterile packing at the surgical site which, according to Dutton, can be uncomfortable, painful and may restrict breathing. Unlike the traditional material, which must be removed after a few days, the plasma gel is absorbed into the sinus cavity and eliminates the need for painful packing removal.
The study compared 16 patients who received platelet gel following surgery with a control group who received traditional packing material. The preliminary results found no adverse reactions to the gel. Patients who received the gel reported less pain and an easier recovery than the control group.
Most surgeries on the sinuses are conducted to relieve chronic sinusitis or to remove polyps. Endoscopic sinus surgery is performed using instruments inserted through the nose to remove thickened and diseased tissue while disturbing as little healthy tissue as possible. The surgery is typically performed as an outpatient procedure under general anesthesia. Doctors usually recommend patients restrict activity for one to two weeks, although this convalescence may be reduced in patients utilizing platelet gel.
"Ive seen many patients who really needed sinus surgery, but they were afraid of the pain," said Dutton. "Patients who received the plasma gel were extremely pleased and surprised. In some cases, patients were asking only two days later if they could return to work."

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
