Pain At Rest

Chronic postoperative pain (POP) is a serious complication of total replacement (TR) of the knee (KJ) and hip (HJ) joints.Objective: to determine the factors associated with POP in patients after TR of KJ or HJ.Patients and methods. The study group consisted of 124 patients with knee osteoarthritis or hip osteoarthritis (age 63.6±9.9 years, 63% women and 37% men) who underwent TR of KJ or HJ. POP was defined as pain ≥40 mm on a numerical rating scale persistent for ≥3 months. Its presence was assessed after 3 and 6 months by telephone survey. Comparison of patients with POP and without it was carried out for a number of factors identified before surgery.Results and discussion. The incidence of POP was 27.4%. There was no difference in the incidence of POP in patients after TR of KJ or HJ: 28.1% and 26.9% (p=0.88). POP was statistically significantly associated with parameters such as higher body mass index (BMI); the intensity of pain at rest; general assessment of impairment; WOMAC index pain, stiffness and overall; severity of symptoms of neuropathic pain (PainDETECT); signs of depression and anxiety (HADS).The risk of POP was significantly higher (p<0.05) with BMI >30 kg/m2 (odds ratio, OR 2.755; 95% confidence interval, CI 1.053–7.206), rest pain ≥40 mm on a visual analog scale (OR 1.349; 95% CI 0.478–3.803), PainDETECT scores ≥13 (OR 3.598; 95% CI 1.048–12.36) and HADS depression ≥8 (OR 2.193; 95% CI 0.745–6.454), presence of ≥2 sources of pain (OR 6.996; 95% CI 2.358–20.756).Conclusion. It was found that the risk of POP after TR of KJ and HJ is higher in patients with overweight, severe preoperative pain, signs of neuropathic pain and depression, as well as in the presence of several sources of pain (except for the affected joint, that was replaced surgically).

Scalp Block

Background: Craniotomy causes acute and chronic pain. Uncontrolled postoperative pain may lead to adverse events. Perioperative scalp nerves block is not only effective in reducing intraoperative hemodynamic response, but it also reduces postoperative pain and postoperative analgesia requirement. Objective: To compare the benefits of adding dexmedetomidine to levobupivacaine in scalp nerves block before craniotomy for the duration of analgesia in supratentorial craniotomy. Materials and Methods: After approval by the Committee for Research, 50 supratentorial craniotomy patients were randomized into two groups. The control group received 30 mL scalp nerves block with 0.25% levobupivacaine with adrenaline 1:200,000, whereas the study group received 30 mL scalp nerves block with 0.25% levobupivacaine with adrenaline 1:200,000 plus dexmedetomidine 1 mcg/kg. The primary outcome was the time to first analgesic requirement postoperatively. The secondary outcomes included intraoperative fentanyl consumption, verbal numerical rating scale, tramadol consumption, and complications during the first 24 hours postoperatively. Results: Patients in the study group had significantly increase time to the first analgesic requirement in postoperative period and reduced intraoperative fentanyl consumption. The median time to first analgesic requirement was 555 (360 to 1,035) minutes in the study group versus 405 (300 to 520) minutes in the control group (p=0.023). Intraoperative fentanyl consumption 125 (75 to 175) mcg in the study group was significantly lower than 200 (150 to 250) mcg in the control group (p=0.02). The verbal numerical rating scale at 1, 4, 8, 12 and 24 hours postoperatively, tramadol consumption, and complications during the first 24 hours postoperatively were not statistically significant different. Conclusion: Preoperative scalp nerves block with 0.25% levobupivacaine with adrenaline (1:200,000) with dexmedetomidine 1 mcg/kg significantly increased the time to first analgesic requirement and reduced intraoperative fentanyl consumption compared to 0.25% levobupivacaine with adrenaline (1:200,000) without perioperative complications.

AbstractScrambler therapy is a noninvasive electroanalgesia technique designed to remodulate the pain system. Despite growing evidence of its efficacy in patients with neuropathic pain, little is known about the clinical factors associated with treatment outcome. We conducted a prospective, open-label, single-arm trial to assess the efficacy and safety of scrambler therapy in patients with chronic neuropathic pain of various etiologies. A post-hoc analysis was performed to investigate whether cluster analysis of the Neuropathic Pain Symptom Inventory (NPSI) profiles could identify a subgroup of patients regarding neuropathic pain phenotype and treatment outcome. Scrambler therapy resulted in a significant decrease in the pain numerical rating scale (NRS) score over 2 weeks of treatment (least squares mean of percentage change from baseline, − 15%; 95% CI − 28% to − 2.4%; p < 0.001). The mean score of Brief Pain Inventory (BPI) interference subdimension was also significantly improved (p = 0.022), while the BPI pain composite score was not. Hierarchical clustering based on the NPSI profiles partitioned the patients into 3 clusters with distinct neuropathic pain phenotypes. Linear mixed-effects model analyses revealed differential response to scrambler therapy across clusters (p = 0.003, pain NRS; p = 0.072, BPI interference subdimension). Treatment response to scrambler therapy appears different depending on the neuropathic pain phenotypes, with more favorable outcomes in patients with preferentially paroxysmal pain rather than persistent pain. Further studies are warranted to confirm that capturing neuropathic pain phenotypes can optimize the use of scrambler therapy.

The Mean

This equivalence, randomized, clinical trial aimed to compare the postoperative pain of root canal therapy (RCT) with pulpotomy with mineral trioxide aggregate (PMTA) or calcium-enriched mixture (PCEM) in permanent mature teeth. In seven academic centers, 550 cariously exposed pulps were included and randomly allocated into PMTA (n = 188), PCEM (n = 194), or RCT (n = 168) arms. Preoperative “Pain Intensity” (PI) on Numerical Rating Scale and postoperative PIs until day 7 were recorded. Patients’ demographic and pre-/intra-/postoperative factors/conditions were recorded/analysed. The arms were homogeneous in terms of demographics. The mean preoperative PIs were similar (P=0.998), the mean sum PIs recorded during 10 postoperative intervals were comparable (P=0.939), and the trend/changes in pain relief were parallel (P=0.821) in all study arms. The incidences of preoperative moderate-severe pain in RCT, PMTA, and PCEM arms were 56.5%, 55.7%, and 56.7%, which after 24 hours considerably decreased to 13.1%, 10.6%, and 12.9%, respectively (P=0.578). The time span of endodontic procedures was statistically different; RCT = 69.73, PMTA = 35.37, and PCEM = 33.62 minutes (P<0.001). Patients with greater preoperative pain, symptomatic apical periodontitis, or presence of PDL widening suffered more pain (P=0.002, 0.035, and 0.023, resp.); however, other pre-/intra-/postoperative factors/conditions were comparable. Pulpotomy with MTA/CEM and RCT demonstrate comparable and effective postoperative pain relief.

AbstractBackgroundNumerous publications describe chronic pain following surgery in both adults and children. However, data in the paediatric population are still sparse and both prevalence of chronic pain after surgery and risk factors of this complication still undetermined.MethodsWe prospectively evaluated the prevalence of chronic pain and its neuropathic pain component at 1 year following correction of idiopathic scoliosis in children less than 18 years of age. Pain was defined as the presence of pain (numerical rating scale – NRS ≥4), the presence of signs of neurologic damage within the area of surgery and the presence of the neuropathic symptoms as a DN4 (Douleur Neuropathique 4) questionnaire ≥4. Factors investigated as potentially associated with the presence of a persistent neuropathic pain were: age, weight, the presence of continuous preoperative pain over the 3 months before surgery, surgical characteristics, pain scores during the first five postoperative days, and DN4 at day 3. Statistical analysis employed univariate analysis and a multivariate logistic regression model.ResultsThirty six patients were included in the study. Nineteen (52.8%) had pain at one year after surgery. Among them 17 (48.2%) had neuropathic pain. Logistic regression found continuous pain over the 3 months preceding surgery and day 1 morphine consumption ≥0.5 mg kg-1 as independent predictors of persistent chronic pain with a neuropathic component. The overall model accuracy was 80.6 and the area under the curve of the model was 0.89 (95% confidence interval 0.78–0.99).ConclusionsThe present study found a high proportion of paediatric patients developing chronic persistent pain after surgical correction of scoliosis diformity. It allows identifying two factors associated with the occurrence of persistent chronic pain with a neuropathic component: the presence of persistent preoperative pain during the 3 months preceeding surgery and postoperative opioid consumption at day 1 –;0.5 mg kg-1ImplicationPatients scheduled for spine surgery and presenting with preoperative pain should be considered at risk of chronic pain after surgery and managed accordingly by the chronic and/or acute pain team. Postoperative opioid consumption should be lowered as possible by using multimodal analgesia and regional analgesia such as postoperative epidural analgesia.

Laparoscopic Sterilization

Background: Effective control of immediate post operative abdominal pain following laparoscopic sterilization is challenging. The objective of the study was to estimate the incidence of immediate severe postoperative pain following laparoscopic sterilization under general anaesthesia by the proportion of patients with the pain assessed on a numerical rating scale. Methods: A cross sectional study was conducted with the approval of institutional review board and ethics committee. Fifty seven participants with written informed consent underwent the study over a period of six months. Pain was assessed by a trained recovery nurse and data was collected and analyzed. The main outcome measure was immediate severe post operative pain on numerical rating scale (NRS). Results: Among the 57 participants, 14 (24.6%) had immediate severe post operative pain with median score of five in the inter quartile range of 0 to 5.75 and 43 (75.4%) participants had no severe pain. Conclusion: The incidence of immediate severe postoperative abdominal pain after laparoscopic sterilization under general anaesthesia is high. Therefore, the management of pain following laparoscopic sterilization requires individually based multimodal analgesia.

Patients Perspective

For many patients, acute pain is a common cause to seek treatment in an Emergency Department (ED). An inadequate assessment could cause inappropriate pain management. The aim of this study was to describe and explain patients’ perceptions of acute pain assessment in the Emergency Department. The data were collected from ED patients (n = 114). Patients reported that nurses were asking about intensity of pain at rest, but only 52% during movement. According to the patients, the most common tools to assess acute pain were the verbal rating scale (VRS; 54% of patients), numerical rating scale (NRS; 28% of patients), and visual analogue scale (VAS; 9.7% of patients). Over twenty per cent of patients stated that ED nurses did not ask about the intensity of pain after analgesic administration. Twenty-four per cent of the patients were not pleased with nursing pain assessment in the ED. The assessment of acute pain is still inadequate in the ED. Therefore, ED nurses need to be more attentive to systematic acute pain management of patients in the ED.

AbstractThe present study aimed to define the prevalence of pain persisting after total knee arthroplasty (TKA) and determine the impact of neuropathic pain. Knee pain after TKA was evaluated in 154 patients (222 knees with osteoarthritis) using a numerical rating scale (NRS) and followed up for a mean of 4.7 years. The patients were classified according to whether they had no or mild pain (NRS ≤ 3), or moderate-to-severe pain (NRS > 3), and then assigned to groups with nociceptive, unclear, or neuropathic pain based on responses to painDETECT questionnaires. Risk factors for these types of pain were determined. The ratio of patients with moderate-to-severe pain was 28% (62 knees). Thirteen patients (21 knees; 9%) experienced unclear pain. Patients with moderate-to-severe or unclear pain had malalignment and lower Knee Society knee scores. In conclusion, a significant number of patients experienced moderate-to-severe and unclear pain after TKA. Moderate-to-severe pain was associated with unclear pain.
