Female vets at risk of miscarriage from anesthetic gases and pesticides
April 03, 2008Maternal occupational exposures and risk of spontaneous abortion in veterinary practice
Female vets run twice the risk of miscarriage as a result of exposure to anaesthetic gases and pesticides, suggests a study published ahead of print in Occupational and Environmental Medicine.
The findings prompt the authors to call for young female vets to be more clearly advised of the risks they run, should they want to become pregnant.
The study is based on a survey of women taking part in the Health Risks of Australian Veterinarians Project (HRAV).
This surveyed all those graduating from Australian veterinary schools between 1960 and 2000.
Of the 5700 graduates contacted, some 2800 responded, of whom 1200 were women.
Between them, these women reported a total of 1355 pregnancies, 940 of which occurred while working in clinical practice, and so were eligible for inclusion in the study.
Women carrying out surgery and exposed to anaesthetic gases that were not filtered out of the atmosphere, for an hour or more a week, were almost 2.5 times more likely to miscarry.
Female vets who used pesticides during the course of their work were also twice as likely to miscarry.
And those who performed more than five x rays a week were around 80% more likely to miscarry than those performing fewer procedures.
When the researchers restricted their analyses to those women graduating more recently-between 1980 and 2000-the results were similar.
The authors warn that female vets of childbearing age "should be fully informed of the possible reproductive effects of ionising radiation, unscavenged anaesthetic gases, and exposure to pesticides."
Women should take protective measures when they are planning to conceive and during pregnancy, they warn. But all staff working in these areas should be aware of the risks and protect themselves accordingly, they suggest.

Scientist gets award for sending people to sleep
One of the UK's top scientists will receive a prestigious award for more than 20 years of research into the mechanisms of action of anaesthetic agents. The American Society of Anesthesiologists (ASA) will make Professor Mervyn Maze, from Imperial College London, the recipient of its Excellence in Research award for 2003 at the Society's Annual Meeting on 13 October in San Francisco. In addition to his clinical work performed as a Consultant Anaesthetist at the Chelsea and Westminster Hospital, Professor Maze's body of research over the last 20 years has contributed to a better understanding of the scientific basis for the mechanisms whereby anaesthetics produce their sleep-inducing effects.

Anaesthetic and Extracorporeal Gas Transfer (Oxford Medical Engineering Series) by Keith L. Dorrington (Author) This book presents a rigorous analysis of a wide range of gas transfer problems of common interest in anesthesia and intensive care. Oxygen uptake and carbon dioxide elimination are prerequisites of the maintenance of human life, and the judicious administration of anesthetic agents remains the primary means of achieving unconsciousness during surgical operations. The book discusses a wide range of equipment used in modern hospital practice to control these aspects of a patient's therapy. Many of the solutions are presented for the first time. This is the first text to cover the whole spectrum of gas transfer from single oxygen masks to artificial lungs in a form which is accessible to both clinicians and biomedical engineering students. | |

Laughing Gas, Viagra, and Lipitor: The Human Stories behind the Drugs We Use by Jie Jack Li (Author) The stories behind drug discovery are fascinating, full of human and scientific interest. This is a book on the history of drug discovery that highlights the intellectual splendor of discoverers as well as the human frailty associated them. History is replete with examples of breakthrough medicines that have saved millions of lives. Ether as an anesthetic by Morton; penicillin as an antibiotic by Fleming; and insulin as an anti-diabetic by Banting are just a few examples. The discoverers of these medicines are doubtlessly benefactors to mankind--for instance, without penicillin, 75% of us probably would not be alive because some of our parents or grandparents would have succumbed to infections. Dr. Jack Li, a medicinal chemist who is intimately involved with drug discovery, has... |
