Ketorolac tromethamine is a non-steroidal anti-inflammatory drug (NSAIDs) that is widely used in the emergency department (ED) for the treatment of moderate-to-severe pain. Ketorolac, like other NSAIDs, exhibits an analgesic ceiling effect and previous research suggests that 10 mg is possibly the ceiling dose. Do the patterns of ketorolac dosing by emergency physicians follow its analgesic ceiling dose? ⋯ The data show that ketorolac was prescribed above its ceiling dose of 10 mg in 97% of patients who received intravenous doses and in 96% of patients receiving intramuscular doses.

ReviewExperimental and procedural pain responses in primary dysmenorrhea: a systematic review.
Primary dysmenorrhea (PD) has been the focus of a number of experimental pain studies. Although a number of reviews exist, few have critically evaluated the existing body of research on PD and experimental and procedural pain. ⋯ However, there is an abundance of conflicting findings, which may be due to significant methodological issues such as inconsistent definitions of PD, wide variation in experimental pain methodologies, and inaccurate assessment of the menstrual cycle. Future research should focus on identifying specific symptoms (i.e., pain threshold ratings) to more clearly define what constitutes PD, establish reliable and valid laboratory testing protocols, and assess the menstrual cycle with greater precision.

Randomized Controlled Trial Comparative Study
Attentional bias modification for acute experimental pain: A randomized controlled trial of retraining early versus later attention on pain severity, threshold and tolerance.
Noxious attentional bias is thought to confer vulnerability to pain, suggesting that modifying the bias could reduce pain outcomes. Herein is presented a randomized controlled trial to test the effects of retraining the dot probe attentional bias at short versus long stimulus durations towards neutral stimuli, and away from threat stimuli, on acute pain experience, in comparison with a placebo control group. ⋯ Testing of the impact of modifying maintained attentional bias on vulnerability to an acute pain stressor. Findings suggested that retraining rapid attentional bias using short exposure durations conferred greater analgesic benefit, in comparison with both the slower bias and sham-training.

To investigate whether pain catastrophizing and personality traits bias recalled ratings of acute pain in an experimental tonic pain model. ⋯ This study demonstrated that memory for painful events in healthy subjects was reasonably accurate over a period of 1 week. Pain catastrophizing biased pain recall, whereas among personality traits only neuroticism exhibited a weak positive association with the recalled ratings.

Low degree of satisfactory individual pain relief in post-operative pain trials.
The majority of clinical trials regarding post-operative pain treatment focuses on the average analgesic efficacy, rather than on efficacy in individual patients. It has been argued, that in acute pain trials, the underlying distributions are often skewed, which makes the average unfit as the only way to measure efficacy. Consequently, dichotomised, individual responder analyses using a predefined 'favourable' response, e.g. Visual Analogue Scale (VAS) pain scores ≤ 30, have recently been suggested as a more clinical relevant outcome. ⋯ Our results indicate that for conventional, explanatory trials of post-operative pain, individual patient's achievement of a favourable response to analgesic treatment is rather low. Future pragmatic clinical trials should focus on both average pain levels and individual responder analyses in order to promote effective pain treatment at the individually patient level.
