Randomized Controlled Trial Multicenter Study Comparative StudyComparison of two ultrasound-guided techniques for greater occipital nerve injections in chronic migraine: a double-blind, randomized, controlled trial.
Two ultrasound (US)-guided techniques for greater occipital nerve (GON) block have been described for the management of headache disorders: a "proximal or central" technique targeting the GON at the level of the second cervical vertebra and a "distal or peripheral" technique targeting the GON at the level of the superior nuchal line. In this multicenter, prospective, randomized control trial, we compared accuracy, effectiveness, and safety of these two techniques in patients with chronic migraines (CMs). ⋯ This study was designed to compare two different US-guided approaches for blocking the GON. Our results demonstrate that both distal and proximal techniques can provide a short-term improvement in headache intensity, reduction in number of headache days per week, and an improvement in sleep interruption. The proximal GON technique may confer more sustained analgesic benefit compared with the distal approach in patients with CM headaches.

Observational StudyValidation of the Dutch version of the critical-care pain observation tool.
Systematic assessment of pain is necessary for adequate treatment of pain. Patient self-reported pain is a superior assessment but is of limited use for intubated patients in the intensive care unit. For these patients, the critical-care pain observation tool (CPOT) has been developed. ⋯ The CPOT is easy to use for systematic assessment of pain. Additional information about the threshold is valuable for use in daily practice.

Children of mothers with chronic pain are at increased risk for poor health, but few studies have examined what characteristics of maternal chronic pain may be associated with children's risk. This study identified subgroups of mothers based on patterns of pain, physical function, and emotional function on the 29-item Patient-Reported Outcomes Measurement Information System® (PROMIS-29®) and evaluated associations between maternal subgroups and children's pain and emotional functioning. ⋯ Patterns of maternal symptoms and functioning were associated with pain frequency and emotional symptoms in children. Further examination of individual differences in mothers with chronic pain that may confer risk for chronic pain and psychological disorders in children is warranted.

Ultrasound therapy reduces persistent post-thoracotomy tactile allodynia and spinal substance P expression in rats.
Therapeutic ultrasound (TU) alleviates nerve injury-associated pain, while the molecular mechanisms are less clear. This is an investigator-initiated experimental study to evaluate the mechanisms and effects of ultrasound on prolonged post-thoracotomy pain in a rodent model. ⋯ The results of this study suggest an increase in mechanical withdrawal thresholds and subcutaneous temperature, as well as a downregulation of spinal substance P and IL-1β, in the group which received ultrasound treatment. The regulation of spinal substance P and IL-1β may mediate potential effects of this non-invasive treatment.

Review Meta AnalysisIntraoperative monitoring of nociception for opioid administration: a meta-analysis of randomized controlled trials.
Under-dosage or over-dosage of intraoperative analgesia can cause harm to patients. Many studies have demonstrated the clinical advantages of nociception monitoring tools, but with some conflicting results. To clarify the issue, this meta-analysis compared the effects of Analgesia Nociception Index (ANI), Surgical Pleth Index (SPI), and pupillometry monitoring methods with those of analgesia management practices of intraoperative opioid administration. ⋯ Nociception monitoring devices seem to have an advantage over standard clinical practice on intraoperative management of analgesia during general anesthesia. Future research should focus on identifying appropriate indicators to objectively assess the degree of pain in children and perform large-scale multicenter trials to prove clinical advantages of nociception measurements during propofol anesthesia.
