Vitamins C and E support breathing following an operation

11.09.2002


Patients who have recently undergone an operation experience less breathing problems after being given a cocktail of vitamins C and E. This is the conclusion reached by researchers from the Leiden University Medical Center following experiments with patients and healthy volunteers.



During the first two to three days after a major abdominal operation, most patients have frequent episodes of airway obstruction and hypoxaemia. This can lead to an increase in the heart rate and blood pressure, which can eventually result in heart muscle damage. An apparently restful patient where nothing seems to be wrong can then suddenly experience an unexpected heart attack.

The breathing problems are a side effect of the necessary sedatives and painkillers which recovering patients receive. The researchers from Leiden discovered that the medicines enhance each other’s undesirable side effects.


In searching for the mechanism behind the breathing problems, it transpired that the administration of vitamins C and E prevents many of the problems. After an encouraging experiment with vitamins C and E on an experimental animal, the researchers subjected 34 healthy men to a test. The volunteers received less oxygen than normal for a period of three minutes. Prior to this some of the men had to take sedatives and vitamins C and E. Another group were not allowed vitamins.

The group who had taken vitamins experienced fewer disruptions to the breathing than the control group who had not taken vitamins. The researchers suspect that stress and pain after an invasive operation bring about a positive effect. Stress and pain keep the body, and thereby the breathing, relatively alert.

In follow-on studies the researchers want to determine whether vitamin C has to be given in combination with vitamin E. They will also study other sorts of sedatives and painkillers. In addition to this they will further examine the role of stress and pain after an operation. Particular attention will be given to the carotid body, a special organ in the carotid artery. This organ seems to function poorly in recovering patients.

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...

Im Focus: New laser joining technologies at ‘K 2016’ trade fair

Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.

K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
