Randomized Controlled TrialThe effects of positive or negative words when assessing postoperative pain.
Negative or harsh words such as 'pain' and 'sting' used to describe sensations prior to potentially painful procedures have been shown to increase pain. We aimed to determine whether the reporting of pain and its severity is affected by the way it is assessed during anaesthesia follow-up after caesarean section. Following caesarean section, 232 women were randomised prior to post-anaesthesia review. ⋯ The assessment of pain after caesarean section, using more positive words, decreases its incidence but does not affect its severity when measured by pain scores. Words that focus the patient on pain during its assessment may lead some to interpret sensations as pain which they might not do otherwise. These findings may have important implications when assessing and researching postoperative pain.

Randomized Controlled Trial Comparative StudyTopical bupivacaine compared to lidocaine with epinephrine for post-tonsillectomy pain relief in children: a randomized controlled study.
To compare the topical administration of bupivacaine hydrochloride, lidocaine hydrochloride with epinephrine and saline in alleviating post tonsillectomy pain. ⋯ Topical administration of bupivacaine hydrochloride proved to provide more efficient pain control than both saline and lidocaine without any drug related complication.

Randomized Controlled Trial Comparative Study
Anterior insula integrates information about salience into perceptual decisions about pain.
The decision as to whether a sensation is perceived as painful does not only depend on sensory input but also on the significance of the stimulus. Here, we show that the degree to which an impending stimulus is interpreted as threatening biases perceptual decisions about pain and that this bias toward pain manifests before stimulus encounter. Using functional magnetic resonance imaging we investigated the neural mechanisms underlying the influence of an experimental manipulation of threat on the perception of laser stimuli as painful. ⋯ This context-dependent classification of a stimulus as painful was predicted by the prestimulus signal level in the anterior insula, suggesting that this structure integrates information about the significance of a stimulus into the decision about pain. The anticipation of pain increased the prestimulus functional connectivity between the anterior insula and the midcingulate cortex (MCC), a region that was significantly more active during stimulation the more a participant was biased to rate the stimulation as painful under high threat. These findings provide evidence that the anterior insula and MCC as a "salience network" integrate information about the significance of an impending stimulation into perceptual decision-making in the context of pain.

Randomized Controlled Trial Comparative StudyA comparison of intraarticular morphine and bupivacaine for pain control and outpatient status after an arthroscopic knee surgery under a low dose of spinal anaesthesia.
Effective pain control is important after an outpatient arthroscopic knee surgery to permit early discharge and improve outcome. The aim of this study was to compare intraarticular morphine and bupivacaine with placebo for postoperative pain control and outpatient status after a knee arthroscopic surgery under a low dose of spinal anaesthesia. After obtaining the ethic committee's approval and written informed consents from 60 adult outpatients undergoing knee arthroscopy, patients were enrolled in this prospective, randomized, double-blinded, placebo-controlled clinical study. ⋯ Side effects were similar among the groups. Patient satisfaction scores were high in the groups M and B. Administration of 5 mg morphine and 20 ml of 0.25% bupivacaine intraarticularly provides better pain relief and shorter discharge time without increasing the side effects than placebo for an outpatient arthroscopic knee surgery performed under a low dose of spinal anaesthesia.
