[Comparison of the preclinical quality of analgesia of emergency physicians and paramedics based on trauma patients]. / Vergleich der präklinischen Analgesiequalität von Notarzt und Notfallsanitäter anhand traumatologischer Patienten.

BACKGROUND: Adequate prehospital pain management is a critical component of emergency medical services. With the introduction of the paramedic profession and the Paramedics Act in Germany, the basis for more extensive competencies of paramedics was established. In many emergency medical service areas it is thus possible for paramedics to perform analgesia and sedation with esketamine/midazolam according to pre-established instructions and/or standard operating procedures. This study assessed the quality of analgesia administered to trauma patients by paramedics compared to emergency medical service physicians. MATERIAL AND METHODS: The study included trauma patients who received prehospital administration of analgesia by either emergency medical service physicians or paramedics and were subsequently admitted to the central emergency department of the Saarland University Hospital. A standardized data collection form was used to collect information from the emergency service protocol and initial emergency department assessment. The evaluation employed descriptive statistical methods and a total of 207 completed records were analyzed. RESULTS: Both professional groups achieved significant pain reduction and fulfilled the criteria for effective pain management (pain reduction: emergency medical service physicians 5.5 ± 2.0/paramedic 4.4 ± 2.1, p < 0.001). Emergency medical service physicians, however, more frequently attained a higher reduction in numerical rating scale scores and administered oxygen. Notable differences were observed in the range of medications used and the dosages. CONCLUSION: This study could show that prehospital analgesia is comparable between emergency medical service physicians and paramedics in terms of effectiveness for trauma patients if the indications are correctly set, while observing pre-existing instructions. With their competencies paramedics are able to perform an effective and safe analgesic treatment within the framework of preformulated procedural instructions, which can be equal to that of an emergency medical service physician.

Perioperative N-acetylcysteine: evidence and indications.

Nonopioid analgesics serve to improve analgesia and limit side effects and risks of perioperative opioids. N-acetylcysteine (NAC), the primary treatment of acetaminophen toxicity, may have perioperative indications, including analgesia. NAC impacts glutathione synthesis, oxidant scavenging, glutamate receptor modulation and neuroinflammation. Potential perioperative benefits include arrhythmia prevention after cardiac surgery, decreased contrast-induced nephropathy, improved post-transplant liver function and superior pulmonary outcomes with general anesthesia. NAC may improve perioperative analgesia, with some studies displaying a reduction in postoperative opioid use. NAC is generally well tolerated with an established safety profile. NAC administration may predispose to gastrointestinal effects, while parenteral administration may carry a risk of anaphylactoid reactions, including bronchospasm. Larger randomized trials may clarify the impact of NAC on perioperative analgesic outcomes.

Nonopioid mediations are important to help pain control after surgery and may decrease risks of opioids. N-acetylcysteine (NAC), the treatment of acetaminophen overdose, decreased inflammation and has other positive effects on the body that may help pain after surgery. Thus, NAC has been studied to prevent abnormal heart rhythms with heart surgery, help kidneys after surgery, improve the liver after liver transplant or other live surgeries and improve breathing after anesthesia. NAC may also decrease pain and the amount of pain medications needed after surgery. While NAC is generally well tolerated and considered safe, stomach upset can occur as can itching or asthma like reactions in certain patients. This review describes how NAC may improve pain, summarizes the other ways NAC may help a patient undergoing surgery, and describes potential side effects when NAC is given.

Assessment of Three Distinct Approaches to Postoperative Pain in Laparoscopic Inguinal Hernia Repair, a Randomized Prospective Study.

Background: Contemporarily, transabdominal preperitoneal repair (TAPP) procedure in inguinal hernia treatment is counted among the routine minimal invasive general surgery practices. Increased patient's comfort, namely less postoperative pain, is considered to be its greatest advantage. However, pain following surgery can still be an important problem. Port site local anesthetic injection (PSLAI), iliohypogastric-/ilioinguinal nerve block (IINB), and preperitoneal local anesthetic spraying (PLAS) are relatively new techniques with sparse data to address this issue. Therefore, we conducted this prospective study to evaluate these three methods in patients who underwent TAPP for inguinal hernia repair. Methods: A total of 99 patients were enrolled and randomized equally into three groups. Every patient received a patient-controlled analgesia (PCA) device. PCA usage, total analgesic demands, and numerical rating scale values were recorded at 2, 6, 12, and 24 hours postoperatively (p.o). Results: Patients' demographic data (age, gender, BMI) did not reveal any significant difference between groups (P > .05). Procedure duration was found to be significantly longer in IINB group compared with others (p < .05). Number of PCA usages, total analgesic demand, additional analgesic requirement did not differ significantly between groups at 24-hour p.o (P > .05). PLAS group was found to have less average NSR score compared with other groups at 24 hours p.o (p < .05). Conclusions: All three procedures show promising outcomes with PLAS technique appearing to be slightly superior in terms of pain management in the immediate postoperative period. However, to reach a conclusion more randomized controlled trials covering various aspects and techniques of minimal invasive approach to inguinal hernia repair should be published.

Lumbar Epidural versus Caudal Epidural for Postoperative Analgesia After Lower Extremity Osteotomy Surgery in Pediatric Patients with Osteogenesis Imperfecta: A Propensity-Matched Cohort Analysis in a Single-Center Over 9 Years.

Purpose: Although pediatric epidural analgesia is a well-established technique used perioperatively. It is unclear whether a lumbar or caudal epidural is suitable for osteogenesis imperfecta (OI) patients, which may be associated with brittle bones and spine deformity. We conducted a retrospective study to investigate and compare the efficacy of the two continuous epidural techniques in pediatric patients undergoing lower extremity osteotomy surgery using a propensity score-matched analysis (PSMA). Patients and Methods: A total of 274 patients were included. Patients' age, weight, and height were adjusted using PSMA. 90 patients were matched for further analysis, with 45 patients in the lumbar epidural group (Group L) and 45 patients in the caudal epidural group (Group C). Pain scores were categorized into three grades: mild (0-3), moderate (4-6), and severe (7-10), and compared between the two groups. Additionally, operation time, operation site, blood loss, scoliosis, oral analgesic medications, and catheter or nerve-related complications were compared. Results: There were no significant differences in operation time, operation site, scoliosis, and blood loss between the two groups. The percentage of moderate to severe pain during movement was significantly higher in Group L than in Group C, with 37.5% versus 17.5% on the second-day post-operation (P=0.039). However, no statistically significant difference was observed on other days. Additionally, there was no significant difference in oral medication consumption and complications between the two groups. Conclusion: Both lumbar and caudal epidural analgesia can be effectively used postoperatively, and a caudal epidural should be considered where performing a lumbar epidural is challenging in OI pediatric patients.

Osteogenesis imperfecta (OI) is a rare genetic disorder that affects the body's connective tissues, particularly the bones and ligaments. It is caused by abnormalities in type I collagen, which leads to skeletal fragility known as "brittle bones". This fragility can cause various issues, including an increased risk of fractures from minor trauma, limb deformities, and unusual fractures such as vertebral compressions. OI patients may also experience spinal manifestations such as scoliosis and kyphosis. Lumbar epidural analgesia has been found to be effective in providing pain relief for surgeries that involve the lower extremities. Additionally, caudal epidural analgesia has also demonstrated its effectiveness in providing postoperative analgesia for surgeries that affect the lower limbs. However, there is still debate about the safety of epidural analgesia in patients with skeletal dysplasias, especially those with OI. Despite this uncertainty, our center, which was supported by the Rare Diseases Public Welfare Organization, has successfully used epidural analgesia since 2015 in the southern part of China for OI surgeries. We conducted a retrospective study to share our experiences of nine years of practice and compare lumbar epidural with caudal epidural using a propensity score matching to balance basic demographics. We also compared the presence of scoliosis. Our findings suggest that both lumbar and caudal epidural analgesia can be safely used in OI patients. In cases where lumbar punctures may pose challenges due to potential spine deformities, the caudal route can be an alternative.

Intranasal dexmedetomidine reduces pain scores in preterm infants during retinopathy of prematurity screening.

Background: This study aimed to investigate the effectiveness of intranasal dexmedetomidine in reducing pain scores during retinopathy of prematurity (ROP) screening examinations in preterm infants. Methods: Infants born at ≤32 weeks of gestational age, undergoing routine ROP examinations in the neonatal intensive care unit, were included in the study and divided into two groups: the standard protocol group (n = 43) and the dexmedetomidine group (n = 56), over a 1-year period. Both groups received standard procedural preparation including swaddling, oral dextrose, and topical anesthesia with proparacaine. The dexmedetomidine group additionally received intranasal dexmedetomidine at a dose of 1 mcg/kg before the procedure. Pain scores (PIPP score), heart rate, respiratory rate, blood pressure, and oxygen saturation were compared at baseline, 1-min, and 5-min during the procedure. Results: There were no significant differences between the groups regarding descriptive and pre-procedure characteristics. In the dexmedetomidine group, the median (25-75p) PIPP score, heart rate, systolic blood pressure and mean (±SD) respiratory rate measured at the 1st minute of the procedure were significantly lower than those in the standard group [PIPP score 10 (8-13) vs. 14 (10-16), p < 0.001; heart rate 165 (153-176) beats/min vs. 182 (17-190) beats/min, p < 0.001; respiratory rate 60 (±7) breaths/min vs. 65(±9) breaths/min, p = 0.002; systolic blood pressure 78 (70-92) mmHg vs. 87 (78-96) mmHg, p = 0.024; respectively] whereas the saturation value was significantly higher (88% (81-95) vs. 84% (70-92), p = 0.036; respectively). By the 5th minute of the procedure, the median (25-75p) PIPP score [4 (2-6) vs. 6 (4-10), p < 0.001], heart rate [148 (143-166) beats/min vs. 162 (152-180) beats/min, p = 0.001] and respiratory rate [56 (54-58) breaths/min vs. 58 (54-62) breaths/min, p = 0.034] were significantly lower, and the saturation level was significantly higher [96% (94-97) vs. 93% (91-96), p = 0.003] in the dexmedetomidine group. Additionally, the frequency of adverse effects was significantly lower in the dexmedetomidine group compared to the standard protocol group (11% vs. 47%, p = 0.001). Conclusion: Administering intranasal dexmedetomidine before ROP screening examinations was associated with a decrease in pain scores among preterm infants. This suggests its potential as an effective and well-tolerated method for pain management during ROP screenings.

The effects of foot orthoses on radiological parameters and pain in children with flexible flat feet: a systematic review and meta-analysis.

Objective: This study aimed to investigate the impact of foot orthoses on foot radiological parameters and pain in children diagnosed with flexible flatfoot. Methods: A comprehensive search was conducted across several databases, including PubMed, Web of Science, EMBASE, Cochrane Library, and EBSCO, covering publications from the inception of each database up to 8 June 2024. The study focused on randomized controlled trials investigating the use of foot orthoses for treating flexible flat feet in children. Four researchers independently reviewed the identified literature, extracted relevant data, assessed the quality of the studies, and performed statistical analyses using RevMan 5.4 software. Results: Six studies involving 297 participants were included. The methodological quality of the included literature ranged from moderate to high. Radiological parameters of the foot improved significantly in older children with flexible flat feet following foot orthotic intervention compared to controls, particularly in the lateral talar-first metatarsal angle [mean difference (MD) = -2.76, 95% confidence interval (95% CI) -4.30 to -1.21, p = 0.0005], lateral talo-heel angle (MD = -5.14, 95% CI -7.76 to -2.52, p = 0.0001) and calcaneal pitch angle (MD = 1.79, 95% CI 0.88-2.69, p = 0.0001). These differences were statistically significant. Additionally, foot orthoses significantly improved the ankle internal rotation angle and reduced foot pain in children with symptomatic flexible flatfoot (MD = -2.51, 95% CI -4.94 to -0.07, p = 0.04). Conclusion: The use of foot orthoses positively impacts the improvement of radiological parameters of the foot and reduces pain in older children with flexible flat feet. However, in younger children with flexible flat feet, the improvement from foot orthoses was not significant, likely due to challenges in radiological measurements caused by the underdevelopment of the ossification centers in the foot. Further studies are needed. Consequently, the results of this meta-analysis support the implementation of an early intervention strategy using foot orthoses for the management of symptomatic flat feet in older children.

The Intra-Articular Combination of Fentanyl, Dexamethasone, Clonidine, Ropivacaine, and Dextrose to Treat Pain Due to Knee Osteoarthritis: A Case Report.

We report a case involving the pain management of a patient with knee osteoarthritis (KOA), where conventional treatment failed to provide pain relief. Instead, a multimodal approach including an intra-articular (IA) injection of a combination of various agents was applied successfully. The pharmacological treatment resulted in minimal improvement. After experiencing failure with IA hyaluronic acid and platelet-rich plasma injections, an IA combination of fentanyl 50 mcg, dexamethasone 8 mg, clonidine 150 mcg, ropivacaine 7.5% 5 ml, dextrose 30% 5 ml, and normal saline 5 ml was applied. The treatment led to a two-year pain relief. The multimodal approach seems to offer satisfactory and encouraging results as the improvement in the quality of life led to favorable physical and psychological outcomes in the patient.

Relationship between pain resilience and pain catastrophizing in older patients after total knee arthroplasty: Chain-mediating effects of cognitive emotion regulation and pain management self-efficacy.

This study aimed to determine whether the relationship between pain resilience and pain catastrophizing in older patients after total knee arthroplasty (TKA) was mediated by cognitive emotion regulation strategies (CERS) and pain management self-efficacy (PMSE). Convenience cluster sampling was used in this cross-sectional study to recruit 382 older adults. The results revealed that pain catastrophizing was negatively correlated with pain resilience, adaptive CERS, and PMSE; however, it was positively correlated with maladaptive CERS (all p < 0.01). Mediation analysis revealed that both CERS (adaptive and maladaptive) and self-management independently and sequentially mediated the relationship between pain resilience and pain catastrophizing in older patients who underwent TKA. These findings demonstrate that CERS (adaptive and maladaptive) and PMSE play chain-mediating roles in the correlation between pain resilience and pain catastrophizing in older patients after TKA.

The Association Between Experienced Discrimination and Pain in the REasons for Geographic and Racial Differences in Stroke (REGARDS) Study.

BACKGROUND: The relationship between experienced discrimination and its effects on pain interference and management among racial disparities is not well explored. This research investigated these associations among Black and White U.S. adults. METHODS: The analysis involved 9369 Black and White adults in the REasons for Geographic and Racial Differences in Stroke (REGARDS), assessing experiences of discrimination, pain interference (SF-12), and pain treatment, incorporating factors like demographics, comorbidities, and stress. RESULTS: Black participants experiencing moderate discrimination were found to have a 41% increased likelihood of pain interference (aOR 1.41, 95% CI 1.02-1.95), similaritythose facing high levels of discrimination also showed a 41% increase (aOR 1.41, 95% CI 1.06-1.86) compared to those without such experiences. White individuals reporting moderate discrimination also faced a heightened risk, with a 21% greater chance of pain interference (aOR 1.21, 95% CI 1.01-1.45). Notably, the presence of moderate discrimination among Black participants correlated with a 12% reduced probability of receiving pain treatment (aOR 0.88, 95% CI 0.56-1.37). Furthermore, Black, and White individuals who reported discrimination when seeking employment had a 33% (aOR 0.67, 95% CI 0.45-0.98) and 32% (aOR 0.68, 95% CI 0.48-0.96) lower likelihood, respectively, of receiving treated pain. CONCLUSION: The study elucidates how discrimination exacerbates pain interference and restricts access to treatment, affecting Black and White individuals differently. These findings underscore an urgent need for strategies to counteract discrimination's negative effects on healthcare outcomes. Addressing these disparities is crucial for advancing health equity and improving the overall quality of care.

Pain in Canadian Long-Term Care Homes: A Call for Action.

Navigating the evaluation and management of pain in long-term care homes is a complex task. Despite an extensive body of literature advocating for a paradigm shift in pain assessment and management within long-term care homes, much more remains to be done. The assessment of pain in long-term care is particularly challenging, given that a substantial proportion of residents live with some degree of cognitive impairment. Individuals living with dementia may encounter difficulties articulating the frequency and intensity of their pain, potentially resulting in an underestimation of their pain. In Canada and in the United States, the interRAI Minimum Data Set 2.0, Minimum Data Set 3.0, and the interRAI Long-Term Care Facilities assessments are administered to capture the presence and intensity of pain. These assessment instruments are used both on admission and quarterly, offering a reliable and validated method for comprehensive assessment. Nonetheless, the daily assessment and documentation of pain across long-term care homes, which is used to inform the interRAI Pain Scale, is not always consistent. The reality is that assessing pain can be inaccurate for several reasons, including the fact that it is rated by long-term care staff with diverse levels of expertise, resources, and education. This call for action explores the current approaches used in pain assessment and management within long-term care homes. The authors not only bring attention to the existing challenges but also emphasize the necessity of considering a more comprehensive assessment approach.

Non-Pharmacological Pain and Stress Management (N-PPSM) in Pediatric Wards: A Nurses' Perspective.

PURPOSE: To describe the nurses' use of non-pharmacological pain and stress management (N-PPSM) in pediatric wards and their perceptions of the benefits and perceived barriers that encourage and limited their use of these methods. METHODS: This was a descriptive cross-sectional study involving 125 nurses working in the pediatric ward of an Indonesian hospital. Data collection utilized modified non-pharmacological method questionnaires, and data analysis involved t-tests and ANOVA. RESULTS: The most widely used N-PPSM by nurses are cognitive methods such as providing education (48%), physical methods by positioning (40%), emotional support (36%), environmental support (45%), and family support (60%). Nurses stated that N-PPSM had few side effects (50.4%), were inexpensive (49.6%), could be performed independently (51.2%), and were easy to use (52.8%). However, during its implementation, there were several obstacles including lack of experience (42.4%), lack of training (48%), lack of equipment (45.6%), nurse belief (36.8%), lack of time (44%), patient unwilling (47.2%), and patient belief (41.6%). Work experience influences the overall utilization of N-PPSM (p-value = .043). CONCLUSION: The findings from this research emphasize the significance of enhanced training for nurses working in the utilization of N-PPSM in pediatric wards. CLINICAL IMPLICATIONS: Findings from this study can enhance nurses' knowledge and competence in using N-PPSM in pediatric wards, thus improving patient care. Hospitals may consider implementing new policies, education, training, and infrastructure to support N-PPSM. Educational institutions can also incorporate these methods into nursing curricula, increasing nurses' awareness and skills in using N-PPSM in pediatric patients.

Herpes Simplex Virus-1 and Hand Sanitizer: A pilot study.

Purpose Herpes Simplex Virus type 1 (HSV-1) is a highly contagious virus that manifests as a painful lesion and recurrences can be distressing to patients. The purpose of this pilot study was to determine if the use of a 70% ethanol alcohol hand sanitizer alters the duration, size of the lesion, level of pain upon administering treatment, and overall daily discomfort during outbreak.Methods This study was a double-blind randomized controlled trial (RCT) using 70% ethanol alcohol hand sanitizer for the experiment and medical grade mineral oil for the control group. The treatment and the control were dispensed in lip gloss applicators for applying medicament. Data was collected through the initial examination, a daily journal, photographs, and a reexamination day. Descriptive statistics and the independent sample t-test were used to analyze data (p=0.05).Results A total of 20 individuals completed the research study: ten in the experimental group and ten in the control group. The mean duration of HSV-1 lesions for the control group was 10.3 days while the mean duration of the HSV-1 lesions for the experimental group was 7.6 days. The mean size of lesions for the control group was 4.87 mm; the mean size for the experimental group was 4.25 mm. The mean pain score for the control group was 1.08 and the mean pain score for the experimental group was 2.74. The mean discomfort score for the control group was 1.33 while the mean discomfort score for the experimental group was 1.72. There was no statistically significant difference between the experimental and control groups in terms of duration, size of lesions, pain, and discomfort.Conclusion Based on the results of this pilot study, 70% ethanol alcohol hand sanitizer did not demonstrate statistical significance in the treatment and management of HSV-1 lesions. Additional research is needed with a larger sample size to determine if statistical differences can be measured.

Challenges of perioperative pain control in opioid use disorder patients following intramedullary nail fixation.

BACKGROUND: Outcomes of patients with opioid use disorder undergoing elective procedures have been well studied, but research is lacking in the orthopaedic trauma population. AIM: The aim was to compare perioperative pain and morphine equivalents required by patients with versus without opioid use disorder following intramedullary nail fixation of femoral or tibial fractures. METHODS: We conducted a retrospective review of all patients with isolated femoral or tibial diaphyseal fractures treated with intramedullary nail fixation. Outcomes were compared between patients with diagnosed opioid use disorder and controls without, including daily morphine equivalents and patient-reported pain scores. RESULTS: Patients with opioid use disorder (n = 42) required greater morphine equivalents and reported higher pain than controls (n = 42) at all time points but did not differ in change of morphine equivalents over the perioperative period. CONCLUSION: This highlights the challenge of perioperative pain control in this population and need for improved specific pain management protocols.

Postoperative Analgesic Regimens and Their Satisfaction Rates-Data from the Swedish Quality Register for Tonsil Surgery.

OBJECTIVE: To describe postoperative analgesic regimens and patient-reported pain-related outcomes after tonsil surgery. METHODS: Cohort study including perioperative data (n = 9274) and patient-reported outcome measures (n = 5080) registered in the Swedish Quality Register for Tonsil Surgery during 2023. RESULTS: After tonsil surgery, 92.7% received at least paracetamol and a NSAID/COX inhibitor, while 6.8% received no NSAID/COX inhibitor. Opioids were prescribed after tonsillectomy to 62.9% of adults and less often to adolescents and children (13-17-year-olds: 48.2%, 6-12-year-olds: 8.8%, 0-5-year-olds: 4.0%). Clonidine was frequently prescribed to 0-5-year-olds after tonsillectomy (54.4%). Overall, 11.7% reported dissatisfaction with the pain treatment, with the highest dissatisfaction rate after tonsillectomy in adolescents (20.6%) and adults (20.0%), and the lowest after tonsillotomy in children (4.9-6.8%). The most common complaint among dissatisfied patients was analgesics not being sufficiently helpful. Adult patients who received addition of opioids were less dissatisfied with the pain treatment (15.9% vs. 25.9%, p < 0.001), but also reported more side effects (5.7% vs. 2.7%, p = 0.039), compared with patients who received only paracetamol and NSAID/COX inhibitors. CONCLUSION: Tonsil surgery patients in Sweden receive various analgesic regimens. Although most are satisfied with pain treatment, there is room for improvement, particularly among adolescents and adults undergoing tonsillectomy. Paracetamol and a NSAID/COX inhibitor seem advisable as basic treatment. However, many patients need more effective treatment. The addition of opioids in adults results in greater satisfaction with pain treatment, but safety issues with opioid prescriptions must be taken into consideration.

Optimizing Pain Management in Cardiac Surgery: A Review of Analgesic Adjuvants.

PURPOSE OF REVIEW: Pain management following cardiac surgery is a critical component in optimizing both short- and long-term patient outcomes, with poor pain management associated with significant acute and chronic opioid use, opioid dependence and a significant rate of opioid related adverse drug events. The significant burden of both acute and chronic pain following cardiac surgery has given rise to the need for multimodel analgesic strategies, to optimize outcomes and minimize side effects. RECENT FINDINGS: While significant research has focused recently on the additive value of peripheral nerve blocks, less emphasis has been given to the value of non-opioid based analgesics in preference to traditional opioid based anesthetic and analgesic strategies. In this review, we examine the evidence for several common analgesics, highlighting the evidence supporting efficacy following cardiac surgery, as well as the safety concerns with each agent. We demonstrate the value of a multimodal analgesic strategy to reduce pain scores and improve patient-centered outcomes, and highlight the need for further studies of combination analgesic strategies.

Factors influencing nurses' use of maggot debridement therapy.

Management of hard-to-heal wounds remains a significant challenge for healthcare systems, with substantial economic burdens. Maggot debridement therapy, using sterile larvae of Lucilia sericata, effectively debrides necrotic tissue and promotes healing, yet its use is limited. This narrative review examines the influences on the use of this form of debridement by registered nurses, focusing on knowledge and attitudes, treatment-related pain, and practical issues. Findings indicate that wound specialist nurses are more knowledgeable and supportive of maggot debridement therapy compared with non-wound specialists, underscoring the need for targeted educational interventions. Pain management is critical, with mixed reports on pain levels, highlighting the necessity for tailored pain-relief strategies. Practical challenges include procurement difficulties and cost, suggesting a need for streamlined processes and clear clinical guidelines. Addressing these barriers through education, research, and improved logistics could enhance the acceptance and use of maggot debridement therapy, improving patient outcomes in wound management.

Criteria for continuous neuraxial analgesia associated with reduced mortality in patients undergoing thoracotomy.

INTRODUCTION: Both thoracic epidural analgesia and thoracic paravertebral analgesia are effective techniques to control pain and minimize the stress response following thoracic surgery. We hypothesized that continuous neuraxial techniques may be associated with a decrease in the incidence of postoperative mortality after thoracotomy. Additionally, we aimed to identify subgroup populations that may benefit more from neuraxial anesthesia. METHOD: 1620 patients who underwent open thoracotomy were included in this retrospective study from the German Thoracic Registry database at four university hospitals. All-cause inpatient mortality was determined for patients who had and did not have neuraxial anesthesia. Logistic regression was used to adjust for and explore various covariates. RESULTS: Continuous neuraxial analgesia was associated with a lower overall mortality in the postoperative period (2.9%, 23/796 vs 5.3%, 44/824, p=0.02) only after the univariate analysis but not the multivariable analysis (OR 0.49, 95 % CI 0.237 to 1.12, p=0.15). In patients with epidural or paravertebral catheters, mortality was significantly lower in the following subgroups: age >75 (5/113 vs 18/77, OR 0.1, 95% CI 0.02 to 0.67, p=0.02), American Society of Anesthesiologists Performance Score >III (11//97 vs 33/155, OR 0.32, 95% CI 0.11 to 0.89, p=0.03), chronic kidney disease (5/83 vs 16/77, OR 0.16, 95% CI 0.03 to 0.82, p=0.03), and postoperative sepsis (9/21 vs 17/25, OR 0.13, 95% CI 0.07 to 0.44, p<0.01). CONCLUSIONS: Neuraxial analgesic techniques are associated with reductions in postoperative mortality after open thoracic surgery in selected patients.

Adductor Canal Block Versus Femoral Nerve Block for Postoperative Pain Management in Anterior Cruciate Ligament Reconstruction: A Prospective Interventional Study.

Background A common knee joint disorder is injury to the anterior cruciate ligament (ACL), which often requires surgery. Proper pain control after the surgery facilitates fast recovery and prevents chronic pain. To provide analgesia for knee procedures, the use of opioids, non-steroidal anti-inflammatory medications, and regional techniques are commonly employed. This study aims to evaluate the efficacy of adductor canal block (ACB) and femoral nerve block (FNB) for postoperative pain management after anterior cruciate ligament reconstructions (ACLRs). Methodology This prospective interventional study included 30 participants scheduled for patellar graft ACLR. They were assigned into groups, i.e., ACB and FNB, with 15 patients each. The evaluation occurred one day before the operation, and all surgical procedures were performed using spinal anesthesia. During the postoperative period, a 10-point visual analog scale (VAS) was utilized to quantify pain intensity at the end of the surgery and at various intervals after the surgery. Patients with a VAS score greater than 4 received either FNB or ACB using bupivacaine 0.125%. Duration of analgesia time, power of quadriceps muscle, and neurologic complications were documented. Results No statistically significant value was observed in the mean duration of analgesia between the patients in ACB (348.33 minutes) and the patients in FNB (363.06 minutes). No motor block was observed in 12 patients who received ACB, while only four patients had a motor-sparing effect among those who received FNB. No neurological adverse effects were observed in the study participants. Conclusions ACB provides an equal duration of analgesia similar to FNB, and ACB significantly spares motor strength and maintains higher quadriceps power than FNB.
