Randomized Controlled Trial
OBJECTIVE
Systemic sclerosis (SSc) is an autoimmune disease with health-related quality of life (HRQoL) high impairment. Pain is of paramount importance to be targeted by therapeutical approaches. Our study aim was to perform an add-on device-based non-invasive neuromodulatory treatment through transcutaneous auricular vagal nerve stimulation (tVNS) in patients with SSc, assessing its effects on pain as primary endpoint and on inflammation, cardiovascular autonomic control and HRQoL.
METHODS
Thirty-two patients with SSc were enrolled based on reported pain assessed through Numeric Rating Scale (NRS). Twenty-one (90% with limited cutaneous SSc) completed a randomised, cross-over, patient-blind trial, in which interventional and active control were used in random order for 4 weeks, interspersed with 4 weeks washout. NRS, Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) Item4 for pain interference, heart rate variability (HRV), serum cytokines and HRQoL questionnaires (Health Assessment Questionnaire, Patient Health Questionnaire-9, University of California, Los Angeles Gastrointestinal Tract, Pittsburgh Sleep Quality Index) were assessed at baseline, at T1 (after 1 month of tVNS or active control), at T2 (after washout) and at T3 (after 1 month of active control or tVNS). T-test for paired data and Wilcoxon signed-rank test for non-normally distributed parameters were performed to compare the effect of tVNS and active control.
RESULTS
NRS pain was significantly reduced by tVNS and not by active control (Mean±SD: -27.7%±21.3% vs -7.7%±26.3%, p=0.002). Interleukin-6 was downregulated in tVNS versus active control (p=0.029). No significant differences were observed in tVNS versus active control for PROMIS-29 Item4, QoL scales and HRV with both spectral and symbolic analyses.
CONCLUSION
tVNS demonstrated to be a safe and non-invasive add-on tool to reduce pain in SSc.

Randomized Controlled Trial
OBJECTIVE
In this randomized, double-blind, sham-controlled trial, we explored the effect of 20 Hz transcutaneous auricular vagus nerve stimulation (taVNS) on gait impairments in Parkinson's disease (PD) patients and investigated the underlying neural mechanism.
METHODS
In total, 22 PD patients and 14 healthy controls were enrolled. PD patients were randomized (1:1) to receive active or sham taVNS (same position as active taVNS group but without releasing current) twice a day for 1 week. Meanwhile, all subjects were measured activation in the bilateral frontal and sensorimotor cortex during usual walking by functional near-infrared spectroscopy.
RESULTS
PD patients showed instable gait with insufficient range of motion during usual walking. Active taVNS improved gait characteristics including step length, stride velocity, stride length, and step length variability compared with sham taVNS after completion of the 7-day therapy. No difference was found in the Unified Parkinson's Disease Rating Scale III, Timed Up and Go, Tinetti Balance, and Gait scores. Moreover, PD patients had higher relative change of oxyhemoglobin in the left dorsolateral prefrontal cortex, pre-motor area, supplementary motor area, primary motor cortex, and primary somatosensory cortex than HCs group during usual walking. Hemodynamic responses in the left primary somatosensory cortex were significantly decreased after taVNS therapy.
CONCLUSION
taVNS can relieve gait impairments and remodel sensorimotor integration in PD patients.

Review
OBJECTIVES
Acupuncture treatment (AT) is commonly utilized for vomiting; however, limited bibliometric analyses exist in this area. Employing a bibliometric approach, we conducted a comprehensive review spanning three decades to assess the research landscape, advancements, and emerging trends in AT for vomiting.
METHODS
We collected the related literature data from the Web of Science Core Collection (WOSCC) from 1990 to 2022. VOSviewer and R studio were used to perform the bibliometric analysis of AT on vomiting. The status of authors, countries, affiliations, annual publications, keywords, and journals were analyzed accordingly.
RESULTS
The earliest relevant paper was published in 1990. Streitberger, K was the most productive author (7 records) and had significant influence (225 reference times, H-Index = 7). The United States had the highest publication count (224 records) and received the most recognition (9719 reference times, H-Index = 52). MEDICINE had the highest number of outputs (34 records), while ANESTHESIA AND ANALGESIA was the most cited journal (1045 reference times). The institution with the most works was Chengdu University of Traditional Chinese Medicine (CDUTCM) (13 records), and the University of California, Los Angeles received the most citations (1252 reference times). Recent and future research hotspots included AT for postoperative vomiting and post-chemotherapy vomiting. Systematic reviews and meta-analyses were the predominant study types.
CONCLUSIONS
The current status and development prospects of AT for vomiting are shown in this study. In addition, this article provides valuable ideas and potential directions for future research activities.

Review
Transcutaneous electrical nerve stimulation (TENS), a pain-alleviating and muscle-relaxing treatment used in physio-therapeutic clinical practice, has recently appeared to be just as effective in dysphonia. This review aimed at clarifying whether TENS can be an effective practice in dysphonia therapy and/or management on its own or combined with other types of interventions and, hence, whether its practice can be a useful, more widespread establishment to speech and language therapy intervention methods. A search was conducted on the PubMed database using specific terms based on the PICO search strategy. Eventually, four randomized controlled studies and four clinical trials were included. The methodological quality of the included studies was evaluated using the physiotherapy evidence-based database (PEDro) assessment tool, and this indicated high-quality research with an average score of 8.43. The studies utilized various TENS devices, predominantly the Dualpex 961 device (frequency of 10 Hz, phase of 200 ms). The assessment methods varied, including auditory perception, vocal therapy, electrostimulation, audio and video perceptual assessments, and laryngeal evaluations. The clinical outcomes of TENS showed a reduction in musculoskeletal pain in various areas, while the acoustic analysis results were significant in only one study. TENS was compared to manual laryngeal therapy (LMT), placebo TENS, and vocal therapy in different studies with mixed results. This review supports the idea that a multidimensional approach, incorporating various therapeutic modalities (TENS, LMT, speech therapy, and vocal training) can yield positive outcomes for patients with voice disorders. Further research is needed to explore the specific mechanisms of action and optimal treatment protocols for TENS in voice therapy.

Randomized Controlled Trial
Dexamethasone and dexmedetomidine as adjuvants to ropivacaine do not prolong analgesia in wound infiltration for lumbar spinal fusion: a prospective randomized controlled study.
BACKGROUND AND OBJECTIVES
Local anesthetics (LAs) are widely used to infiltrate into surgical wounds for postoperative analgesia. Different adjuvants like dexamethasone and dexmedetomidine, when added to LA agents, could improve and prolong analgesia. The aim of this trial was to evaluate the analgesic efficacy and opioid-sparing properties of dexamethasone and dexmedetomidine when added to ropivacaine for wound infiltration in transforaminal lumbar interbody fusion (TLIF).
METHODS
We conducted a controlled study among 68 adult patients undergoing TLIF, which was prospective, randomized and double-blind in nature. The participants were divided into four equal groups at random. Group R was given 150 mg of 1% ropivacaine (15 mL) and 15 mL of normal saline. Group R + DXM received 150 mg of 1% ropivacaine (15 mL) and 10 mg of dexamethasone (15 mL). Group R + DEX received 150 mg of 1% ropivacaine (15 mL) and 1 µg/kg of dexmedetomidine (15 mL). Lastly, group R + DXM + DEX was given 150 mg of 1% ropivacaine (15 mL), 10 mg of dexamethasone and 1 µg/kg of dexmedetomidine (15 mL). The primary focus was on the length of pain relief provided. Additionally, secondary evaluations included the amount of hydromorphone taken after surgery, the numerical rating scale and safety assessments within 48 h after the operation.
RESULTS
Based on the p value (P > 0.05), there was no significant variance in the duration of pain relief or the total usage of hydromorphone after surgery across the four groups. Similarly, the numerical rating scale scores at rest and during activity at 6-, 12-, 24- and 48-h post-surgery for all four groups showed no difference (P > 0.05). However, the incidence of delayed anesthesia recovery was slightly higher in group R + DEX and group R + DXM + DEX when compared to group R or group R + DXM. Furthermore, there were no significant differences between the four groups in terms of vomiting, nausea, dizziness or delayed anesthesia recovery.
CONCLUSION
For wound infiltration in TLIF, the addition of dexamethasone and dexmedetomidine to ropivacaine did not result in any clinically significant reduction in pain or opioid consumption and could prompt some side effects.

Review
Effective postoperative analgesia using multimodal approach improves maternal and neonatal outcomes after cesarean delivery. The use of neuraxial approach (local anesthetic and opioids) and intravenous adjunctive drugs, such as nonsteroidal anti-inflammatory drugs and acetaminophen, currently represents the standard regimen for post-cesarean delivery analgesia. Peripheral nerve blocks may be considered in patients who are unable to receive neuraxial techniques; these blocks may also be used as a rescue technique in selected patients. This review discusses the relevant anatomy, current evidence, and advantages and disadvantages of the various peripheral nerve block techniques. Further research is warranted to compare the analgesic efficacy of these techniques, especially newer blocks (e.g., quadratus lumborum blocks and erector spinae plane blocks). Moreover, future studies should determine the safety profile of these blocks (e.g., fascial plane blocks) in the obstetric population because of its increased susceptibility to local anesthetic toxicity.

Supracondylar fractures of the distal humerus are the most common fracture around the elbow in children. A thorough initial assessment must be conducted to identify any associated neurovascular injury and carefully documented. The assessment should include a vascular examination of the radial pulse, temperature, colour and capillary refill time. A neurological examination must comment on the motor and sensory function of the radial, median and ulnar nerves. X-rays allow an evaluation of the fracture location and type, and the degree of displacement. Immobilisation in plaster is the gold standard treatment for paediatric supracondylar fracture of the humerus where the degree of displacement is within acceptable parameters. Casting should be followed by orthogonal radiographs and a repeat neurovascular assessment of the limb. Oral analgesia and safety netting information should be provided on discharge, and the child reviewed in a fracture clinic within 1 week of the injury. The British Orthopaedic Association Standards for Trauma and Orthopaedics for supracondylar fractures of the humerus in children are useful for junior orthopaedic and emergency medicine clinicians to refer to when dealing with these injuries.

Pain Physician Sep 2023Optimal intrathecal dosing regimens for hydromorphone are not well established for analgesia after abdominal surgery. (Review)
Review
BACKGROUND
Optimal intrathecal dosing regimens for hydromorphone are not well established for analgesia after abdominal surgery.
OBJECTIVES
We reviewed intrathecal hydromorphone doses and complications because dosing variability has been observed among anesthesiologists. We hypothesized that increasing doses of intrathecal hydromorphone would be associated with improved postoperative analgesia, but with increased rates of opioid-related adverse events.
STUDY DESIGN
Retrospective analysis.
SETTING
A high-volume academic referral center in the United States.
METHODS
A retrospective study was conducted of adults undergoing abdominal surgery under general anesthesia supplemented preoperatively with intrathecal hydromorphone for postoperative analgesia from May 5, 2018, through May 31, 2021. Patients were categorized into 3 hydromorphone dosing groups: low-dose (50-100 µg), middle-dose (101-199 µg), and high-dose (200-300 µg). Multivariable logistic regression models were used to assess rates of severe postoperative pain, severe opioid-related adverse events, oversedation, and pruritus in the postanesthesia care unit (PACU) and within 24 hours after PACU discharge.
RESULTS
Of 1,846 patients identified, 1,235 (66.9%) were in the low-dose group; 321 (17.3%), middle-dose group; and 290 (15.7%), high-dose group. Patients receiving the 2 higher doses had more extensive procedures. An unadjusted analysis showed differing rates of severe pain in the PACU by group: 306 (24.8%) in the low-dose, 73 (22.7%) middle-dose, and 45 (15.5%) in the high-dose group (P = 0.003); these differences, however, were no longer significant after an adjusted analysis (P = 0.34). Ten severe opioid-related events occurred; all were recognized in the PACU. Five events each occurred in the low-dose and high-dose groups versus none in the middle-dose group (P = 0.02). No other differences were identified with adjusted analyses.
LIMITATIONS
Limitations of our study include its retrospective design and its conduct at a single center, along with the apparent, but difficult to characterize, treatment biases in hydromorphone dosing.
CONCLUSIONS
No dose response was observed between intrathecal hydromorphone dose and postoperative analgesia, a finding that may reflect treatment bias. Higher rates of severe opioid-related events were detected for patients receiving high-dose hydromorphone in the PACU, but all other safety outcomes were similar between dosing regimens.

Review
PURPOSE OF REVIEW
In order to better treat pain, we must understand its architecture and pathways. Many modulatory approaches of pain management strategies are only poorly understood. This review aims to provide a theoretical framework of pain perception and modulation in order to assist in clinical understanding and research of analgesia and anesthesia.
RECENT FINDINGS
Limitations of traditional models for pain have driven the application of new data analysis models. The Bayesian principle of predictive coding has found increasing application in neuroscientific research, providing a promising theoretical background for the principles of consciousness and perception. It can be applied to the subjective perception of pain. Pain perception can be viewed as a continuous hierarchical process of bottom-up sensory inputs colliding with top-down modulations and prior experiences, involving multiple cortical and subcortical hubs of the pain matrix. Predictive coding provides a mathematical model for this interplay.

Randomized Controlled Trial
OBJECTIVE
Preemptive multimodal analgesia is a frequently utilized method for controlling pain after total knee arthroplasty (TKA). So far, no studies have specifically examined the efficacy of adding acetaminophen to preemptive multimodal analgesia in TKA. The current work aimed to assess the efficacy of adding acetaminophen to preemptive multimodal analgesia for clinical pain management after TKA.
METHODS
This was a double-blinded randomized study including 80 cases randomized to the acetaminophen and control groups, respectively. The acetaminophen group was administered celecoxib at 400 mg, pregabalin at 150 mg, and acetaminophen at 300 mg 2 h before TKA. Control patients were administered celecoxib, pregabalin, and placebo. The primary outcome was postsurgical use of morphine hydrochloride for rescue analgesia. Secondary outcomes included the time to the initial rescue analgesia, postsurgical pain as determined by a visual analogue scale (VAS), functional recovery as reflected by the range of knee motion and ambulation distance, hospitalization duration, and complication rates. Continuous data with normal and skewed distributions were compared by the Student's t test and the Mann-Whitney U test, respectively. Categorical variables were compared by the Pearson's chi-squared test.
RESULTS
The control and acetaminophen groups were comparable in postoperative 0-24 h morphine consumption (11.3 ± 6.5 mg vs 12.3 ± 7.7 mg, P = 0.445) and total morphine consumption (17.3 ± 10.1 mg vs 19.3 ± 9.4 mg, P = 0.242). Additionally, time to the initial rescue analgesia, postoperative VAS score at any time point, postoperative functional recovery of the knee, and hospitalization duration were similar in both groups. Both groups also had similar occurrence rates of postoperative complications.
CONCLUSIONS
In this study, adding acetaminophen to preoperative preemptive multimodal analgesia did not decrease postoperative morphine use or ameliorate pain relief. The efficacy of adding acetaminophen to preemptive multimodal analgesia in TKA need to be further explored in future studies.
