The objective of the current study was to compare the anaesthetic efficacy of supplemental intraligamentary (IL) injection of 4% articaine with that of 2% lidocaine in the mandibular first and second molars with irreversible pulpitis after an ineffective inferior alveolar nerve block injection (IANB) using the same anaesthetic in a randomised triple-blind clinical trial. Seventy-six adult patients, who were diagnosed with irreversible pulpitis in the mandibular first or second molars, were divided into 2 groups and received IANB randomly. In patients with lip numbness, anaesthesia was evaluated with the cold and electrical pulp (EPT) tests, and if the reported number on EPT was below 100, supplemental IL injection was administered using the same anaesthetic. ⋯ Furthermore, there was no significant difference in the success rates of supplemental IL injection with lidocaine between the mandibular first and second molars. However, there was a significant difference in the success rates of supplemental IL injection with articaine between the mandibular first and second molars. Moreover, supplemental IL injections indicated no significant difference in the anaesthetic efficacy between articaine and lidocaine; nevertheless, they were more effective in the mandibular second molars, especially with articaine.

Several predictors have been shown to be independently associated with chronic postsurgical pain for gastrointestinal surgery, but few studies have investigated the factors associated with acute postsurgical pain (APSP). The aim of this study was to identify the predictors of APSP intensity and severity through investigating demographic, psychological, and clinical variables. ⋯ These results suggested that the predictors for APSP intensity following gastrointestinal surgery included analgesic consumption, preoperative anxiety, and expected postsurgical pain, which were also the risk factors for APSP severity.

Randomized Controlled Trial
Comparison of the Effects of Hugo's Point Massage and Play on IV-Line Placement Pain in Children: A Randomized Clinical Trial.
Reduction of intravenous line placement pain is one of the most important nursing priorities in the pediatric wards. The present study was aimed at comparing the effect of Hugo's point massage and play on the severity of IV-line placement pain in hospitalized children aged 3-6 years in the pediatric ward. 72 children were selected and assigned randomly to three groups, i.e., control, play, and Hugo point massage. In the massage group, the middle angle between the first and second bones of the palm of the opposite hand was massaged, and the playgroup encouraged bubble-making play. ⋯ The result of the post hoc Scheffe test also showed a statistically significant difference between the mean intensity of IV-line placement pain in both play therapy and Hugo's point massage groups (p=0.028; p < 0.05). Moreover, this test showed that the playgroup children felt less pain than Hugo's point and control group children. This study showed that, in comparison with Hugo's point massage, the play was a more effective way for reducing pain caused by IV-line placement in children, and pediatric nurses can play a significant role in reducing and managing children's pain by using it.

Dermatomal somatosensory evoked potentials (DSEPs) are used to evaluate abnormalities of the somatosensory tract. There have been some studies on the diagnostic value of DSEP in radiculopathy, but it is still controversial. The purpose of our study is to evaluate the diagnostic implication and clinical relevance of DSEPs in patients with radiculopathy by comparing DSEP findings to radiculopathy symptoms and intervertebral foramen (IVF) or spinal canal stenosis in lumbar magnetic resonance imaging (MRI). ⋯ This paper could be helpful in the electrophysiologic diagnosis of lumbar radiculopathy.

Medial branch nerve block (MBB) and facet joint injections (FJIs) can be used to manage axial low back pain. Although there have been studies comparing the MBB and FJI effects, a few studies have compared the therapeutic effects of both interventions combined with each separate intervention. This study aimed to compare the pain relief effect of MBB, FJI, and combined treatment with MBB and FJI in patients with axial low back pain. ⋯ MBB, FJI, and combined treatment with MBB and FJI can reduce axial low back pain and improve secondary functional degradation. Although combined treatment with MBB and FJI required a longer intervention time, it did not have a pain relief effect superior to that of MBB or FJI alone.
