The American Society of Anesthesiologists (ASA) Closed Claims database was started in 1985 to study anaesthesia injuries to improve patient safety, now containing 8954 claims with 5230 claims since 1990. Over the decades, claims for surgical anaesthesia decreased, while claims for acute and chronic pain management increased. In the 2000s, chronic pain management involved 18%, acute pain managem...

Large observational studies of accurate data can provide similar results to more arduous and expensive randomised controlled trials. In 2012, the National Hip Fracture Database extended its dataset to include 'type of anaesthesia' data fields. We analysed 65 535 patient record sets to determine differences in outcome. Type of anaesthesia was recorded in 59 191 (90%) patients. Omitting patients ...

OBJECTIVE To assess knowledge and attitudes of Pakistani women towards different options of anaesthesia techniques for caesarean section and also to identify their sources of information about them. METHODS A total of 410 women scheduled for elective caesarean section were enrolled after informed written consent in this hospital based cross sectional survey. The women were interviewed prefera...

BACKGROUND The effect of resident training in anaesthesiology on operating room (OR) economics is an issue of debate. Comparisons of anaesthesia process times between residents and consultants might be systematically skewed by interactions of anaesthesia technique and patient factors. METHODS In this prospective, observational study, we analysed anaesthesia process times in 599 cases performe...

This paper presents results from analyzing the vul nerability of security critical software applications to malicious threats and anomalous events using an au tomated fault injection analysis approach The work is based on the well understood premise that a large proportion of security violations result from errors in software source code and con guration The method ology employs software fault ...

ology of rheologic studies and discussed their value and limitations. This second article presents data from recent rheologic studies of hyaluronic acid and calcium hydroxylapatite fillers and discusses how these data correlate with our current understanding and use of these fillers. Rheology—the study of flow-related properties—has been recognized for almost a century as being relevant to a nu...

BACKGROUND The aim of this retrospective study was to compare the failure rates and the frequency of anaesthesia-related complications of two different methods of regional anaesthesia used for carotid endarterectomy--cervical epidural (CE) anaesthesia and cervical plexus block (CPB). METHODS The study included 1828 carotid endarterectomies performed in 1455 patients between 1996 and 2006. A c...

There has been an increasing trend worldwide to use regional anaesthesia for operative deliveries. The Confidential Enquiry into Maternal Deaths in the United Kingdom has demonstrated a steady decline in the anaesthesia-related deaths since the introduction of regional anaesthesia. There are lower morbidity profiles in mothers delivering under regional anaesthesia as well as better infant Apgar...

The feasibility of using computer-based EEG spectral analysis to monitor the level of anaesthesia during nitrous oxide-alphaprodine anaesthesia has been established by this study. At present, this system is capable of estimating the level of anaesthesia correctly from 55 per cent to 80 per cent of the time. There are several possible clinical applications of such a monitoring system during anae...
