Dentists find alternative to ’potentially risky’ general anaesthetic

02.09.2004


Dental experts have developed a new sedation procedure which could relieve pressure on hospitals and allow patients to avoid potentially risky general anaesthetics. Clinical trials on more than 600 children with extreme dental problems who would usually attend hospital for a general anaesthetic (GA) for dental treatment, found the new procedure was completely successful in 93 per cent of cases.

Researchers at the UK’s University of Newcastle upon Tyne carried out the Government-funded study at Queensway Anxiety Management Clinic in Billingham, Teesside. The team say the findings suggest the time is right to reform dental services so alternatives to hospital-based GAs for dental procedures can be offered in specialist practices like Queensway.

The results, which are published in the September issue of the academic journal Anaesthesia, showed that giving patients a sedative known as midazolam and a measured amount of two gases with normal local anaesthetic was a viable alternative to a GA for dental procedures.



The children, whose condition or anxiety was too severe to be treated using conventional techniques such as local anaesthetic alone, felt no pain under sedation, and although they remained conscious throughout they did not remember their treatment after it was completed. Not only did they avoid the risks of a general anaesthetic, they were sedated in a dentist’s chair, which suggests the procedure could be used as a way of reducing hospital waiting lists and freeing beds.

GAs for dental procedures have traditionally been used where dentists feel the patient’s care cannot be managed using conventional techniques. The UK Government banned dental surgeries from performing them in January 2002, following several patient deaths, and it transferred responsibility for dental GAs to hospitals.

The Newcastle University clinical trials tested three new sedative procedures on groups of children who had been referred to Queensway Anxiety Management Clinic.

In the group given a combination of nitrous oxide and sevoflurane and intravenous midazolam by a consultant anaesthetist, 249 out of the 267 children – 93 per cent - completed their treatment successfully.

Dr Paul Averley, principal dentist at Queensway Anxiety Management Clinic, who developed the techniques and is working on the programme of research in collaboration with Newcastle University’s School of Dental Sciences and Centre for Health Services Research, said: "Dentists are often suspicious about procedures that involve sedating children with intravenous agents like midazolam. However, we showed that it worked very effectively when combined with inhalation agents and we saw no adverse reactions. "The children were treated by a highly trained team, which included a consultant anaesthetist, and they also had have the benefit of shorter waiting times and treatment in familiar surroundings.

Dr Averley, who qualified as a dentist at Newcastle University in 1990, added: "It’s two years since the Government ban on GDAs in dental practices and we now hope the profession can start to share best practice on evidence-based sedation techniques. Health authorities could consider establishing specialist services throughout the country, together with facilities where teams can be trained to administer the procedures."

Commenting on the significance of this work, Dr Nick Girdler, Head of the Sedation Department at Newcastle Dental Hospital & School, said: "These results are very exciting. The technique gives real hope to children who are too scared to have teeth extracted or filled using standard sedation techniques. "It complements other types of sedation for children, such as nitrous oxide sedation (laughing gas), and newer techniques including oral midazolam sedation (a sedative drink). It is hoped that this research will give children and parents more choice, especially if other specialist dental clinics, with appropriate anaesthetic support, can be set up to offer these services".

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
