Randomized Controlled Trial Comparative StudyRandomised controlled trial comparing the Ambu® aScope™2 with a conventional fibreoptic bronchoscope in orotracheal intubation of anaesthetised adult patients.
Fibreoptic intubation remains an essential skill for anaesthetists to master. In addition to the reusable fibrescope, an alternative disposable videoscope is available (aScope(™)2, Ambu®, Ballerup, Denmark). A total of 60 anaesthetised adult patients were randomised to either having orotracheal intubation using the aScope 2 or a Karl Storz fibrescope. ⋯ All of the other subjective outcomes were similar between the two groups, except that operators found it easier to use the aScope 2 compared to the fibrescope. There was no significant difference in clinical performance between the aScope 2 and the Karl Storz fibreoptic bronchoscope. The aScope's practicality, disposability and recently improved version (aScope(™)3) potentially make it an acceptable alternative to the reusable fibrescope.

Historical ArticlePain relief in childbirth: changing historical and feminist perspectives.
Pain during human childbirth is ubiquitous and severe. Opium and its derivatives constitute the oldest effective method of pain relief and have been used in childbirth for several thousand years, along with numerous folk medicines and remedies. Interference with childbirth pain has always been criticised by doctors and clergy. ⋯ They popularised the use of 'twilight sleep', a combination of morphine and scopolamine, which fell into disrepute as its adverse effects became known. From the 1960s, as epidural analgesia became more popular, a second wave of feminists took the opposite position, calling for a return to non-medicalised, female-controlled, 'natural' childbirth and, in some cases, valorising the importance of the pain experience as empowering for women. However, from the 1990s, a third wave of feminist thought has begun to emerge, revalidating a woman's right to choose a 'technological', pain-free birth, rather than a 'natural' one, and regarding this as a legitimate feminist position.

Case ReportsThe changing face of malignant hyperthermia: less fulimant, more insidious.
Modern anaesthetic techniques have resulted in the clinical presentation of malignant hyperthermia to be more often indolent and/or insidious than truly fulminant, as previously known in the anaesthetic community. We present four recently referred cases to illustrate this point: one late-onset case, two patients with slowly progressive hypercapnia as the sole sign and a fourth patient with postoperative myalgias and elevated creatine kinase. ⋯ The more insidious character of malignant hyperthermia is most likely due to the lower triggering potency of modern volatile anaesthetics, the mitigating effects of several intravenous drugs (neuromuscular blocking agents, alpha 2 adrenergic receptor agonists, beta adrenergic blockade) or techniques (neuraxial anaesthesia) and the routine use of end-tidal CO2 monitoring leading to the early withdrawal of triggering drugs. Awareness among anaesthetists of this change in presentation is important since the clinical diagnosis is often more doubtful and, if corroborative evidence is not sought, the diagnosis may be delayed or missed altogether.

Biography Historical ArticleBecoming a physician anaesthetist-difficulties encountered for half a century.
William T. G. Morton was not the first to use ether or nitrous oxide as an anaesthetic. ⋯ Some were prolific writers and helped spread the use of anaesthesia. However, attracting physicians to this new discipline proved difficult and there were segments of the medical establishment and society who were unwilling to accept this most significant advancement. In this article, we examine the reasons why many physicians and patients resisted the use of anaesthesia.
