Placebo by proxy expectations toward acupuncture change over time: a survey comparing parental expectations to acupuncture pre- and postoperatively.

BACKGROUND: Patients entering a treatment have expectancy to outcome based on their previous experience, the information received, and the credibility of the treatment. Once the treatment has started, patients may detect and interpret contextual cues and somatic state. Influenced and conditioned by positive or negative interpretations, their reappraisal may improve or worsen the treatment outcome. The aims were to investigate whether parental pre-treatment expectancies towards acupuncture differ compared to post-treatment expectancies, and assess predictors for possible change of parental expectancy. Further, we wanted to explore whether the change correlates with the treatment outcome, i.e. postoperative vomiting in children. METHODS: Two hundred and eighty-two parents completed per- and 24 h postoperatively a survey on their expectancy to acupuncture treatment for alleviation of postoperative vomiting in children. The survey was embedded in a randomised controlled trial. RESULTS: Parental expectancy to acupuncture treatment changed over time. The changes were predicted by several variables such as children's gender, parents' age and education, previous experiences, and assignment to treatment group. The strongest predictor was parental anxiety to their child undergoing surgery. Further, the change of parental expectancy was correlated with postoperative vomiting. CONCLUSIONS: Anxious parents are prone to change their expectancy in a positive direction during the treatment period, which in turn may improve treatment outcome. Acupuncture therapists in clinical practice should pay a special attention to the potential that lies here, and acknowledge parental anxiety as a possible facilitator, and not a barrier, to elicit placebo by proxy effects. Further research to expand the findings of the present study into other treatments is in order. Future research should also provide more knowledge about how parental expectancy changes over time, and how different factors predict and produce change of parental expectancy.

"Placebo effect is probably what we refer to as patient healing power": A qualitative pilot study examining how Norwegian complementary therapists reflect on their practice.

BACKGROUND: Complementary therapists spend considerable time with their patients, especially in the first consultation. The communication between patients and their therapists is important for raising consciousness and activation of the patient's self-healing power. Thus, the aims in this study were to delineate what complementary therapists regard as essential in patient consultations, their view of the healing process, and how the therapists understand the placebo effect and its position in the healing process. METHODS: Semi-structured individual interviews (n = 4), focus group interview (n = 1) and participant observation were conducted among four different complementary therapists in a Norwegian community. The text data was transcribed verbatim and the analysis of the material was conducted according to conventional and direct content analysis. Some codes were predefined and others were defined during the analysis. RESULTS: The pilot study showed that the implemented methods seems feasible and fit well with the aims of this study. Complementary therapists (chiropractor, naprapath (musculoskeletal therapist), acupuncturist and acupuncturist/homeopath) representing four different complementary modalities participated. A combination of the conversation and examination during the first consultation formed the basis for the therapist's choice of treatment. A successful consultation was characterized by a fruitful relationship between the therapist and the patient. Moreover, the therapist needs to be humble and show the patient respect. Patients' positive beliefs and expectations about the treatment play a significant role in the healing process. The more hope the therapist can bring about, the more easily the patient can start believing that it is possible to get well. CONCLUSION: This was a pilot study. Therefore the findings should be appreciated as limited and preliminary. Therapists' and patients' mutual understanding and treatment goals were essential for a successful consultation. The therapists emphasized their professional skills and therapeutic competence as important when building fruitful relationships with their patients. Exerting authority and making the patient feel confident were essential factors for a successful healing process. The complementary therapists understood the placebo effect as the patient's self-healing power, resulting from establishing trust and belief in the treatment process.

Acupuncture and related techniques in ambulatory anesthesia.

PURPOSE OF REVIEW: Along with a growing awareness of quality in healthcare, has come a focus on postanesthetic morbidities, which still remain challenging in our daily practice of anesthesia. Acupuncture and related techniques (acustimulation) are often suggested to be adequate treatments with low cost and minimal adverse effects. This review focuses on the current evidence and applicability of these techniques for use in ambulatory anesthesia. RECENT FINDINGS: Trials exploring the effects of acustimulation may produce ambiguous results and sometimes be difficult to evaluate. Controversies still remain as to the clinical relevance. Recent trials suggest that acustimulation may prevent postoperative pain, nausea and vomiting. There are also promising results for the use of the techniques in reducing preoperative anxiety, postoperative shivering and emergence delirium. SUMMARY: Pharmacological drug treatment may be only partially effective and produce an adverse event. Research suggests that acustimulation may alleviate postoperative morbidities, although the body of evidence of the effect is equivocal. The treatments are easy to perform, and adverse events and costs are minimal. It may be profitable to implement this beneficial treatment to asmbulatory patients.

Implementation of acupuncture and acupressure under surgical procedures in children: a pilot study.

OBJECTIVE: To test the feasibility of research on acupuncture and acupressure for children undergoing tonsillectomy and/or adenoidectomy. METHODS: During January and February 2008, 20 patients from the ordinary waiting list at Lovisenberg Diakonale Hospital in Oslo were randomised to either acupuncture while under anaesthesia or standard care as control. The authors gave acupuncture at Pericardium 6 (P6) at a depth of approximately 0.7 cm on both forearms. The needles were removed when the patient was transferred to the recovery unit and replaced with acupressure wristbands. The outcome measure in the pilot study was to explore if acupuncture and acupressure could be implemented without extending the anaesthesia time and surgical time. This pilot study also tested the feasibility of the research protocol for future investigation in the field, with postoperative nausea, vomiting and retching as the primary end points for effect. RESULTS: The study showed no delay in the surgical procedure and no additional anaesthesia time attributable to the introduction of acupuncture. The protocol was found to be feasible with regard to performance of the main study. Vomiting occurred in five patients in the treatment group and 10 patients in the control group. The total numbers of vomiting events were 13 in the treatment group and 19 in the control group. CONCLUSION: The results encouraged performance of the main study according to the research protocol.

Nurse anaesthetist students' experiences of patient dignity in perioperative practice-a hermeneutic study.

Aim: The aim of the study was to describe how nurse anaesthetist students experienced patient dignity in perioperative practice. Design: A hermeneutical design and the critical incident technique were used to obtain experiences from practice. Method: In the Autumn of 2015, after participating in a mandatory lecture on ethics, 23 nurse anaesthetist students reported their experiences and interpretation concerning violation and preservation of patients' dignity in the operating theatre. The text, which was a compilation of descriptions of 35 incidents, was analysed by using hermeneutical text interpretation. Findings: The text revealed three main themes preserving patients' dignity: allocating time to the patient, inviting the patient to participate and shielding the patient's body. Furthermore, three main themes of dignity violation were identified: alienation, backbiting and violation of intimate sphere. Conclusion: Discussion and reflection based on the personal experience of the students during their practice are ways to strengthen ethical awareness and promote an ethical and dignified caring culture.

Placebo by Proxy--the Influence of Parental Anxiety and Expectancy on Postoperative Morbidities in Children.

BACKGROUND: Placebo effects emerging from expectancies of relatives, also known as placebo by proxy, is a rather unexplored field. In this study, we assume a correlation between parental anxiety/expectancy and postoperative morbidities in children. Accordingly, a reduction of parental anxiety is expected to enhance the effect of treatment. METHODS: From October 2012 to June 2013, parents of 282 children completed a self-report closed-ended questionnaire embedded in a main RCT at three ambulatory care centers. RESULTS: There were no significant associations between parental expectancy or anxiety and children experiencing vomiting and pain. CONCLUSION: The present study is the first to investigate placebo by proxy in acupuncture treatment for children. The findings were not able to demonstrate any placebo effect by proxy. Unknown confounders and limitations of methods may have contributed to the negative findings. Thus, the findings must be read with precaution, as the possibility of a type II error cannot be excluded. TRIAL REGISTRATION: ClinicalTrials.gov NCT01729052.

Acupuncture versus usual care for postoperative nausea and vomiting in children after tonsillectomy/adenoidectomy: a pragmatic, multicentre, double-blinded, randomised trial.

OBJECTIVES: To investigate the effect of a standardised acupuncture on nausea and vomiting in children after tonsillectomy with or without adenoidectomy when possible placebo effects were precluded. METHODS: A pragmatic, multicentre, double-blinded, randomised controlled trial. The study was conducted over 10 months in 2012-2013 at three ambulatory clinics. Two hundred and eighty-two children, age 1-11 years, American Society of Anesthesiologists grade ≤II, were included. To equalise expectancy effects, all parents were told that their child would receive acupuncture. However, children were randomly allocated to perioperative bilateral needling acupuncture at PC6, depth 7 mm, mean time 17 min (SD 5-45) during anaesthesia plus usual care, or to usual care only. The regional ethics committee approved this approach. Primary endpoints were nausea and vomiting 24 h postoperatively. RESULTS: This study did not demonstrate any effect of acupuncture (95% CI) compared with standard care. The overall vomiting in the acupuncture and usual-care groups was 44.2% and 47.9%, respectively. Nausea was experienced by 31.7% in the acupuncture group and by 32.6% in the usual-care group. The test power was acceptable for comparisons of vomiting. CONCLUSIONS: The findings suggest that when controlling for possible placebo effects standardised PC6 acupuncture needling during anaesthesia without further stimulation of PC6 is not effective in reducing nausea and vomiting in children after tonsillectomy with or without adenoidectomy. Future studies should investigate acupuncture treatment which balances adequate dose and technique and a feasible, child-friendly acupuncture treatment.

Perioperative acupuncture and postoperative acupressure can prevent postoperative vomiting following paediatric tonsillectomy or adenoidectomy: a pragmatic randomised controlled trial.

OBJECTIVE: To investigate the effectiveness of acupuncture and acupressure as supplements to standard treatment for postoperative vomiting in children undergoing tonsillectomy and/or adenoidectomy. METHODS: A pragmatic, open, block-randomised controlled trial. The results were analysed according to the intention-to-treat principle. The study was conducted without extra resources in a normal setting at the day-surgery department of Lovisenberg Diakonale Hospital in Oslo. 154 children with an American Society of Anesthesiologists grade 1-2, weighing at least 10 kg, were included. Children with concomitant gastrointestinal diseases, emesis or antiemetic treatment <24 h preoperatively, rash or local infection over the actual acupuncture points were excluded together with patients whose parents' informed consent could not be obtained. The intervention group received acupuncture at pericardium 6 bilaterally, at a depth of approximately 0.7 cm with a median of 21 min during anaesthesia, followed by acupressure wristbands for 24 h and standard treatment. The control group received standard treatment. The primary end point was the occurrence of vomiting or retching during 24 h postoperatively. RESULTS: Children in the acustimulation group experienced less retching and vomiting than the control group-46.8% versus 66.2% (p=0.015). The effect of acustimulation was specifically pronounced in girls and children aged 1-3 years. CONCLUSION: This trial indicates the effectiveness of acustimulation as an adjunct to standard treatment. The results should encourage and promote the implementation of acustimulation for postoperative vomiting in children undergoing adenoidectomy or tonsillectomy.
