A randomised trial published in the British Journal of Anaesthesia describes hypnosis compared with general anaesthesia in 60 children undergoing superficial surgery. We describe a definition of clinical hypnosis; the goals and conduct of hypnotic communication; and its potential as both an adjunct and, in suitable cases, alternative to traditional pharmacological anaesthesia.

Chronic low back pain (CLBP) is a debilitating and burdensome condition, and new treatment strategies are needed. This study aimed to evaluate (1) the feasibility of undertaking a controlled clinical trial investigating a novel intervention for people with CLBP: hypnotically reinforced pain science education, and (2) the acceptability of the intervention as rated by participants. feasibility and intervention acceptability criteria were set.

Patient satisfaction is routinely used to assess the quality of care in medicine. In the field of anesthesia, research has been primarily directed toward developing satisfaction measures in adults with little attention paid to the pediatric population. Satisfaction in pediatric anesthesia and perioperative care is poorly understood.

Introduction: The Serious Harm and Morbidity "SHAM" grading system has previously been proposed to categorize the risks associated with the use of invasive placebos in peripheral nerve block research. SHAM grades range from 0 (no potential complications, eg, using standard analgesia techniques as a comparator) through to 4 (risk of major complications, eg, performing a sub-Tenon's block and injecting normal saline). A study in 2011 found that 52% of studies of peripheral nerve blocks had SHAM grades of 3 or more.

Introduction: This study aimed to identify the way information is described and presented by childbirth educators during antenatal classes for expectant parents, and analyse the language structures used when discussing labour and birth.

Methods: This cross-sectional study of antenatal education was conducted at a single tertiary referral centre for Maternity Care in Western Sydney, Australia. All childbirth educators (n=3) were recorded whilst providing information to parents during antenatal classes.

Background: The tension between the ideal of informed consent and the reality of the process is under-investigated in spine surgery. Guidelines around consent imply a logical, plain-speaking process with a clear endpoint, agreement and signature yet surgeons' surveys and patient interviews suggest that surgeons' explanation is anecdotally variable and patient understanding remains poor. To obtain a more authentic reflection of practice, spine surgeons obtaining 'informed consent' for non-instrumented spine surgery were studied via video recording and risk/benefit discussions were analysed.

Background: Maternal hypotension is the most frequent complication of spinal anaesthesia for caesarean section. It can be associated with nausea or vomiting and may pose serious risks to the mother (unconsciousness, pulmonary aspiration) and baby (hypoxia, acidosis, neurological injury).

Objectives: To assess the effects of prophylactic interventions for hypotension following spinal anaesthesia for caesarean section.

Anaesthetists are key members of teams caring for burn-injured children in almost every aspect of their management. Their role can involve initial resuscitation, intensive care, analgesia, and anaesthesia for multiple procedures both acutely and subsequently for scar management. As key members of burns management teams, effective communication with patients and their families as well as other members of the burn care team is vital.

At April 2020, this review has been withdrawn. It is correct at the date of publication, and previous versions can be accessed in the 'Other versions' tab on the Cochrane Library. We are aware of new studies to potentially change the conclusions, however the update did not meet the timelines and expectations of Cochrane and the PaPaS review group.

Background: Single-shot spinal anaesthesia (SSS) and combined spinal-epidural (CSE) anaesthesia are both commonly used for caesarean section anaesthesia. Spinals offer technical simplicity and rapid onset of nerve blockade which can be associated with hypotension. CSE anaesthesia allows for more gradual onset and also prolongation of the anaesthesia through use of a catheter.

This article describes two common hypnotic communication techniques that can be used in anesthesiology and more generally for a variety of medical applications. First, the LAURS (listening, acceptance, utilization, reframing, suggestion) hypnotic communication structure is detailed. This technique allows clinicians to rapidly build patient rapport and maximize the chance of a suggestion being realized.

Unlabelled: The language structures used by antenatal educators have not been previously researched in the context of antenatal childbirth classes. Epidural analgesia for labour is a common, and a frequently asked about, component of antenatal education for parents in hospitals providing maternity care.

Aim Of The Study: We aimed to identify the way information is described and presented by childbirth educators to assess content and determine which language structures such as metaphor, suggestion, information and storytelling are utilized.

Background: Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain, and is widely used as a form of pain relief in labour. However, there are concerns about unintended adverse effects on the mother and infant. This is an update of an existing Cochrane Review (Epidural versus non-epidural or no analgesia in labour), last published in 2011.

Objective: This research examined whether negative and positive arousal emotions modify the relationship between experience level and cue utilization among anesthetists.

Background: The capacity of a practitioner to form precise associations between clusters of features (e.g.

Background/aims: To determine the prevalence of psychological distress in Australian junior medical officers (JMO) and investigate the determinants associated with psychological distress over a 3-year (2014-2016) period.

Methods: JMO were surveyed using the 2014-2016 JMO Census (n = 220, 399 and 466 each year; response rate approximately 15%). Levels of psychological distress were assessed using the Kessler Psychological Distress Scale (K10).

Background: This review is one in a series of Cochrane reviews investigating pain management for childbirth. These reviews all contribute to an overview of systematic reviews of pain management for women in labour, and share a generic protocol. This review updates an earlier version of the review of the same title.

Background: The impact of communication within the perioperative period is an area of increasing research interest. Suggestions are phrases or actions that can lead to subconscious nonvolitional changes in patient perception, mood, and/or behavior. Statements functioning as suggestions may induce positive or negative perceptual responses and experiences.

Background: Induction of general anaesthesia can be distressing for children. Non-pharmacological methods for reducing anxiety and improving co-operation may avoid the adverse effects of preoperative sedation.

Objectives: To assess the effects of non-pharmacological interventions in assisting induction of anaesthesia in children by reducing their anxiety, distress or increasing their co-operation.

Background: Emergence agitation (EA) is a common behavioral disturbance after sevoflurane anesthesia in children. Propofol 1 mg · kg(-1) bolus at the end of sevoflurane anesthesia has had mixed results in reducing the incidence of EA, whereas propofol infusion throughout anesthesia maintenance seems effective but is more complex to administer. If a simple, short transition to propofol anesthesia was found to be effective in reducing EA, this could enhance the recovery of children following sevoflurane anesthesia.

Background: Sevoflurane is an inhaled volatile anaesthetic that is widely used in paediatric anaesthetic practice. Since its introduction, postoperative behavioural disturbance known as emergence agitation (EA) or emergence delirium (ED) has been recognized as a problem that may occur during recovery from sevoflurane anaesthesia. For the purpose of this systematic review, EA has been used to describe this clinical entity.

Background: Postoperative pain remains a significant problem following paediatric surgery. Premedication with a suitable agent may improve its management. Clonidine is an alpha-2 adrenergic agonist which has sedative, anxiolytic and analgesic properties.
