ABSTRACT CONTEXT AND OBJECTIVES: Effective postoperative analgesia is important for reducing the incidence of chronic pain. This study evaluated the effect of preoperative gabapentin on postoperative analgesia and the incidence of chronic pain among patients undergoing carpal tunnel syndrome surgical treatment. DESIGN AND SETTINGS: Randomized, double-blind controlled trial, Federal University of São Paulo Pain Clinic. METHODS: Forty patients aged 18 years or over were randomized into two groups: Gabapentin Group received 600 mg of gabapentin preoperatively, one hour prior to surgery, and Control Group received placebo. All the patients received intravenous regional anesthesia comprising 1% lidocaine. Midazolam was used for sedation if needed. Paracetamol was administered for postoperative analgesia as needed. Codeine was used additionally if the paracetamol was insufficient. The following were evaluated: postoperative pain intensity (over a six-month period), incidence of postoperative neuropathic pain (over a six-month period), need for intraoperative sedation, and use of postoperative paracetamol and codeine. The presence of neuropathic pain was established using the DN4 (Douleur Neuropathique 4) questionnaire. Complex regional pain syndrome was diagnosed using the Budapest questionnaire. RESULTS: No differences in the need for sedation, control over postoperative pain or incidence of chronic pain syndromes (neuropathic or complex regional pain syndrome) were observed. No differences in postoperative paracetamol and codeine consumption were observed. CONCLUSIONS: Preoperative gabapentin (600 mg) did not improve postoperative pain control, and did not reduce the incidence of chronic pain among patients undergoing carpal tunnel syndrome surgery.

Objectives: Analyze the literature data on the incidence and manifestation of carpal tunnel syndrome (CTS), as well as the pathogenesis and treatment options. Perform a specially designed, validated test - Pain Detection. Evaluate the objective state of patients with CTS - sensory impairment, compression test. Assess patients’ neurologic and neurophysiologic data before and after the blockade and evaluate its effectiveness. Perform a specially designed, validated test - Patients` Global Impression of Change scale (PGIC) one month after corticosteroid injection (CSI).Methods and Materials: The study includes an analysis of 55 arms of patients of different age with mild and moderate CTS who came for a neurological examination at the Neurology Outpatient Department of the Pauls Stradiņš Clinical University Hospital during the period of 01.08.2018 – 01.01.2019. All patients were analyzed clinically and neurophysiologically before CSI and one month after CSI. A Pain Detect scale, PGIC scale, compression tests and sensory tests were used for the evaluation of clinical symptom. A median nerve sensory and motor nerve conduction study was performed.Results: According to the Pain Detect scale, 60% of patients showed neuropathic pain before CSI, and 78% of patients presented clinical effectiveness after CSI. 98% of patients present clinical effectiveness after CSI in the PGIC scale. 85% of patients had improvement in neurophysiological studies – motor distal latency decreased after CSI. Before CSI, the average motor distal latency was 5.7ms (range 4.5-12.9ms SD±1.5), which was on average 130% from the maximal norm (range 102- 293 SD±36). After the CSI, the average motor distal latency was 5.2ms (range 3.8-10.7ms SD±1.3), which was on average 120% from the maximal norm (range 88-243 SD±30). We didn’t find any significant correlation between the improvement of the patient's clinical condition and the improvement of electrophysiological outcomes.Conclusions: The study concludes that the Pain Detect sensitivity for neuropathic pain evaluation of patients with CTS is 60%. Patients show clinical and neurophysiological improvement after CSI, but there is no correlation between neurophysiological and clinical improvement. The study concludes that the PGIC scale can be used to quickly assess the effectiveness of therapy.

A better understanding of the connection between risk factors associated with pain and function may assist therapists in optimizing therapeutic programs. This study applied mathematical modeling to analyze the relationship of psychological, psychophysical, and motor variables with pain, function, and symptom severity using Bayesian linear regressions (BLR) and self-organizing maps (SOMs) in carpal tunnel syndrome (CTS). The novelty of this work was a transfer of the symmetry mathematical background to a neuropathic pain condition, whose symptoms can be either unilateral or bilateral. Duration of symptoms, pain intensity, function, symptom severity, depressive levels, pinch tip grip force, and pressure pain thresholds (PPTs) over the ulnar, radial, and median nerve trunks, the cervical spine, the carpal tunnel, and the tibialis anterior were collected in 208 women suffering from CTS. The first BLR model revealed that symptom severity, PPTs over the radial nerve, and function had significant correlations with pain intensity. The second BLR showed that symptom severity, depressive levels, pain intensity, and years with pain were associated with function. The third model demonstrated that pain intensity and function were associated with symptom severity. The SOMs visualized these correlations among variables, i.e., clinical, psychophysical, and physical, and identified a subgroup of women with CTS exhibiting worse clinical features, higher pressure sensitivity, and lower pinch tip grip force. Therefore, the application of mathematical modeling identified some interactions among the intensity of pain, function, and symptom severity in women with CTS.

The purpose of this study was to identify the clinical characteristics of neuropathic pain in patients with carpal tunnel syndrome. We retrospectively reviewed 143 hands in 127 patients with carpal tunnel syndrome. The neuropathic pain was determined by using the painDETECT as a self-administered psychometric questionnaire to distinguish neuropathic pain. There were no significant differences in the characteristics of the patients with and without neuropathic pain. However, there were significant differences in the pain scores between those with and without neuropathic pain (p < 0.01). Furthermore, there was a significant difference between the existence of night pain in these patients (p < 0.01). Based on the results of the current study, we conclude that it is important to be aware of, and consider the existence of neuropathic pain during the treatment of patients with carpal tunnel syndrome with night pain or a high score on the numerical rating scales of pain.

ABSTRACT Carpal tunnel syndrome (CTS) is a condition involving nerve entrapment that often leads to chronic neuropathic pain. We aimed to evaluate sleep quality and related parameters in diabetic and non-diabetic CTS patients. Method This study included a total of 366 patients with chronic CTS. These patients’ sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI) and depression using the Beck Depression Inventory (BDI). The severity of neuropathic pain was evaluated using the Douleur Neuropathique-4 (DN4) questionnaire and a visual analogue scale (VAS). Results In the non-diabetic patient group, the total PSQI score was found to affect BDI and VAS, while in the diabetic patient group, the duration of symptoms affected VAS, BDI and fasting glucose levels. Conclusion For diabetic patients, hyperglycemia depression and chronification of neuropathic pain may lead to deterioration of sleep quality. Therefore, consideration of these parameters in the treatment may break a vicious cycle.

Purpose.The aim of this study was to determine the risk factors of neuropathic pain (NP) in the patient with carpal tunnel syndrome (CTS) before and after the carpal tunnel release.Materials and Methods.One hundred and two CTS patients were enrolled in the study. The pain score was measured by the visual analogue score. NP was determined by the painDETECT (PD) questionnaire. All subjects were divided into 3 groups at 12 weeks after surgery: an Improved, Unchanged, and Worsened group. The risk factors of worsening NP after surgery were evaluated.Results.We found that 36% and 18% of patients with CTS had neuropathic pain before and 12 weeks after surgery, respectively, and pain was significantly stronger than in those without NP. The PD score of eight hands worsened after surgery. In the “Improved group,” the average age at the surgery was younger and the pain score was lower than in the “Unchanged group.”Conclusions.The surgery was very effective on NP of CTS; however, the PD in 7% of hands worsened after surgery. Risk factors before surgery that predicted worse NP after surgery were found to be a younger age, weaker pain, and the absence of night pain.
