Inhibition of electroacupuncture on nociceptive responses of dorsal horn neurons evoked by noxious colorectal distention in an intensity-dependent manner.
The transmission of visceral nociception can be inhibited by electroacupuncture (EA) at the spinal level. However, relationships between current intensity and EA-induced analgesia are still lacking. This study compares the effects of different intensities of EA at local acupoints and heterotopic acupoints on nociceptive responses of spinal wide dynamic range (WDR) neurons induced by noxious colorectal distension (CRD). ⋯ Within a certain range, the nociceptive responses of dorsal horn neurons induced by CRD could be inhibited by EA in an intensity-dependent manner.

Pain experiences and intrapersonal change among patients with chronic non-cancer pain after using a pain diary: a mixed-methods study.
Pain diaries are a valuable self-assessment tool; however, their use in chronic non-cancer pain has received limited attention. In this study, we examined the effect of pain diary use on pain intensity, interference, and intrapersonal change in patients with chronic non-cancer pain. ⋯ Use of a pain diary in patients with chronic non-cancer pain was associated with reduced pain intensity and improved mood as well as function. Further controlled trials examining the long-term effects of pain diaries are warranted.

Who benefits from multimodal rehabilitation - an exploration of pain, psychological distress, and life impacts in over 35,000 chronic pain patients identified in the Swedish Quality Registry for Pain Rehabilitation.
Chronic pain patients frequently suffer from psychological symptoms. There is no consensus concerning the prevalence of severe anxiety and depressive symptoms and the strength of the associations between pain intensity and psychological distress. Although an important aspect of the clinical picture is understanding how the pain condition impacts life, little is known about the relative importance of pain and psychological symptoms for individual's life impact. The aims of this study were to identify subgroups of pain patients; to analyze if pain, psychological distress, and life impact variables influence subgrouping; and to investigate how patients in the subgroups benefit from treatments. ⋯ The results emphasize the need to assess both pain and psychological distress and not take for granted that pain involves high psychological stress in the individual case. Not all patients benefit from MMRP. A better matching between common clinical pictures and the content of MMRPs may help improve results. We only partly found support for treatment resistance in patients with psychological distress burden.

Failed dural puncture during needle-through-needle combined spinal-epidural anesthesia: a case series.
Combined spinal-epidural (CSE) anesthesia is a widely used neuraxial anesthetic technique. In clinical practice, failed dural puncture during needle-through-needle technique occasionally occurs, with incidence of 5%-29%. We radiologically evaluated four cases of failed dural puncture during needle-through-needle CSE anesthesia. ⋯ Excessive paramedian deviation of the epidural needle may affect dural puncture during needle-through-needle CSE technique. Moreover, wrong passage of the spinal needle through Tuohy curve instead of the back hole, may contribute to failure of dural puncture.

Ultrasound-guided continuous serratus anterior plane block: dexmedetomidine as an adjunctive analgesic with levobupivacaine for post-thoracotomy pain. A prospective randomized controlled study.
Purpose: The study aimed to evaluate the analgesic efficiency of dexmedetomidine (DEX) when added to levobupivacaine in continuous ultrasound-guided serratus anterior plane block (SAPB) performed at the end of major thoracic surgery. Methods: This randomized, double-blind trial included 50 adults undergoing thoracic surgery. Continuous SAPB was performed at the end of surgery. ⋯ Conclusions: Continuous SAPB with levobupivacaine plus DEX seems to be a promising analgesic alternative following thoracotomy. Combined with IV paracetamol, this approach provided adequate analgesia and proper sedation. Trial registration: ISRCTN registry; study ID: ISRCTN35517318.
