M-POSSUM, an effective risk assessment system prior to operation

10.10.2007
Based on POSSUM, a system suggested by some British scholars more than 10 years ago, a team led by Dr. Lian-An Ding has established the M-POSSUM evaluation system with the aim of improving the accuracy and effectiveness of the original system.

Numerous scoring systems currently exist for risk assessment, including the Glasgow Coma Scale (GCS), the Acute Physiology and Chronic Health Evaluation (APACHE), and the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM). These scoring systems are important tools in deciding the course of treatment.

The best known and most widely used scoring systems, APACHE and POSSUM, have limitations when applied to high-risk, general surgical patients. APACHE is best suited to intensive care patients, but requires 24 h of observation, and weighing tables for individual disease states. POSSUM, on the other hand, is limited by its somewhat subjective nature and incomplete evaluation of cardiac signs. They propose a modified POSSUM (M-POSSUM) as a reasonable, practical and objective scoring system that can be used across a broad disease spectrum in general surgery.

In contrast to APACHE and POSSUM, the present scoring system is based on GCS, APACHE, and POSSUM, and supplemented with the following indices: hepatic function (bilirubin), blood glucose level, gastrointestinal function and nutritional status (albumin). However, body temperature, heart rate, sodium and potassium, which are always normal preoperatively in general surgery, are not considered. To avoid repetition, the duration of operation, volume of intraoperative blood loss and surgery are considered as operative wound indices for a malignant tumor. M-POSSUM also takes blood pressure and electrocardiographic activity into consideration during anesthesia.

Through a study of a series of more than 200 patients, They show that M-POSSUM is more accurate than POSSUM and APACHE II in predicting postoperative morbidity and mortality. M-POSSUM therefore seems to be a better model for risk assessment. Further studies are now being carried out.

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: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

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...
