Increased opioid consumption in neoadjuvant immunotherapy plus chemotherapy for patients with non-small-cell lung cancer: A multicenter, prospective cohort study.

AIMS: PD-1 block was reported to impair opioid-induced antinociception and affect cognitive function in rodents and non-human primates. This prospective multicenter cohort study aims to investigate the possible impact of neoadjuvant immunotherapy with PD-1 antibody on perioperative analgesic effect of opioids and postoperative delirium (POD) for non-small-cell lung cancer (NSCLC) patients. METHODS: Eighty-four NSCLC patients from three medical centers with neoadjuvant chemoimmunotherapy (nCIT) or chemotherapy (nCT) were enrolled. The primary outcome is the total perioperative opioid consumption defined as the sum of intraoperative and postoperative opioid use within 3 days after surgery. Secondary outcomes compromise of incidence of POD, pain intensity, and number of analgesic pump press. Tumor prognostic parameters and perioperative change of inflammatory cytokines and soluble PD-L1 level were also recorded. RESULTS: Eighty-one patients were included in the final analysis. The total opioid consumption (sufentanil equivalent) perioperatively in the nCIT group was significantly higher than that in the nCT group, with mean difference of 60.39 µg, 95% CI (25.58-95.19), p < 0.001. Multiple linear regression analysis showed that nCIT was correlated with increased total opioid consumption (ß = 0.305; 95% CI, 0.152-0.459; p < 0.001). The incidence of moderate-to-severe pain and cumulative analgesic pump press within 72 h was significantly higher in subjects with nCIT. There is no statistical difference in incidence of POD between groups within 72 h after surgery. The pathologic complete response rate and perioperative serum IL-6 level were higher in the nCIT group than in the nCT group. CONCLUSION: Patients with NSCLC receiving nCIT warrant increased opioid consumption perioperatively and suffered from more postoperative pain. CLINICAL TRIAL REGISTRATION: NCT05273827.

Outpatient Patient Controlled Analgesia (PCA) for the Palliative Care Patient.

This study explores the under-researched domain of patient-controlled analgesia (PCA) for cancer pain management in adult outpatients, focusing on the transition from patient-controlled analgesia pumps (PCA pump) to oral medications. While existing literature primarily addresses the use of PCA in inpatient settings, this descriptive study investigates the initiation of outpatient PCA in palliative care patients. The retrospective chart review includes data from all admissions between July 1, 2014, and December 31, 2020. Among the 49 identified patients, 41 were admitted for cancer-related pain, with an indication for PCA such as insufficient pain relief, highly fluctuating pain, or inadequate response to other routes. Of these patients, 13 were successfully transitioned from outpatient PCA to oral opioids. The study underscores the effective use of PCA as a transitional tool following a pain crisis that necessitates inpatient admission. Future research avenues could explore healthcare utilization, length of stay, and required outpatient resources, such as home visits or telehealth, for optimal PCA use in outpatient settings.

Use of Opioids and Epidural Anaesthesia in Labor Analgesia as Important Risk Factors for Apparent Postpartum Urinary Retention: A Case-Control Study.

BACKGROUND: Labor analgesic interventions, particularly the use of opioids and epidural anaesthesia, have raised concerns regarding their potential impact on postpartum urinary retention (PUR), necessitating a comprehensive investigation into their association with this clinical outcome. METHODS: This retrospective case-control study analysed clinical data from postpartum patients at our hospital from January 2023 to December 2023. Anaesthetic methods, including opioid and non-opioid drug usage, epidural analgesia and non-use of analgesia, were assessed. Logistic regression analysis was also performed to determine important associations with apparent PUR. RESULTS: This study included clinical data from 54 postpartum patients with PUR and 54 without urinary retention. A higher percentage of women with apparent PUR received opioids during labour compared with those without PUR (p = 0.033). Conversely, a lower percentage of women with apparent PUR received non-opioid analgesics compared with those without PUR (p = 0.026). In addition, a higher percentage of women with apparent PUR received epidural analgesia compared with those without PUR (p = 0.041). Logistic regression analysis demonstrated that opioid consumption during labour was significantly associated with apparent PUR (odds ratio (OR) = 2.469, p = 0.022). By contrast, non-opioid consumption during labour was inversely associated with apparent PUR (OR = 0.297, 95% CI = 0.123-0.681, p = 0.005). In addition, the use of epidural analgesia during labour showed a remarkable association with apparent PUR (OR = 2.857, 95% CI = 1.289-6.552, p = 0.011). CONCLUSIONS: Opioid use during labour and the use of epidural analgesia were identified as important risk factors for apparent PUR. These findings emphasise the need for a thoughtful and balanced approach to analgesic management during labour to minimise the risk of PUR in obstetric patients.

Preoperative anxiety, postoperative pain tolerance and analgesia consumption: A prospective cohort study.

BACKGROUND: Anxiety affects the patient's perception of postoperative pain and causes a significant increase in the consumption of analgesia postoperatively. OBJECTIVE: This study assesses the relationship between preoperative anxiety, postoperative pain and postoperative pethidine consumption. METHODS: A prospective cohort design was used. Data were collected from 100 patients who were undergoing a laparoscopic cholecystectomy at St Joseph Hospital, Jerusalem. Pain-controlled analgesia with pethidine was utilised to manage pain throughout the postoperative period. The visual analogue scale scores and pethidine consumption of all patients were recorded. FINDINGS: Participants' mean level of pain was higher in the preoperative period (mean visual analogue scale = 1.3) compared with their mean level of pain in the postoperative period (mean visual analogue scale = 0.5). There is a statistically significant difference between the participants' level of anxiety and postoperative pain level (p < 0.001). Gender, weight, level of education and smoking were predictors of developing preoperative anxiety. Also, gender, smoking and medication were statistically significant predictors of developing postoperative pain. Furthermore, gender, medical history and medication were statistically significant predictors of pethidine consumption postoperatively. CONCLUSIONS: The preoperative anxiety reduction intervention should be promoted and implemented as routine care for all surgical patients.

The effect of longer epidural duration after open pancreaticoduodenectomy on pain and mobilisation: A retrospective single-centre analysis.

BACKGROUND: The optimal length of epidural use following open pancreaticoduodenectomy has not been defined. The aim of this study was to investigate whether the length of patient-controlled epidural analgesia affected pain and ability to mobilise on epidural termination following open pancreaticoduodenectomy in the context of enhanced recovery after surgery. METHODS: A retrospective single-centre cohort analysis was performed between November 2015 and December 2021 on patients who underwent open pancreaticoduodenectomy. As part of a continual review process of the enhanced recovery after surgery protocol, patient-controlled epidural analgesia duration changed allowing stratification of patients into either three- or five-day patient-controlled epidural analgesia groups. RESULTS: Of the 196 patients identified, 157 were included with 80 (50.9%) and 77 (49.1%) allocated to the three-day and five-day patient-controlled epidural analgesia groups, respectively. Patient-controlled epidural analgesia termination on postoperative day 3 was associated with transiently higher pain and less mobilisation, although no greater rescue analgesia requirement. Conversely, longer patient-controlled epidural analgesia usage following open pancreaticoduodenectomy was associated with less pain and greater mobilisation in the immediate postoperative period. CONCLUSIONS: Earlier patient-controlled epidural analgesia termination transiently leads to increased pain and decreased mobilisation following open pancreaticoduodenectomy. Ensuring appropriate analgesia requirements or longer patient-controlled epidural analgesia usage should be considered to avoid patient discomfort and enhance recovery.

Self-defined former smokers consume the highest opioid quantities following knee and shoulder arthroscopy.

PURPOSE: To identify risk factors associated with increased postoperative opioid consumption and inferior pain outcomes following knee and shoulder arthroscopy. METHODS: Using the data set from the NonOpioid Prescriptions after Arthroscopic Surgery in Canada (NO PAin) trial, eight prognostic factors were chosen a priori to evaluate their effect on opioid consumption and patient-reported pain following arthroscopic knee and shoulder surgery. The primary outcome was the number of oral morphine equivalents (OMEs) consumed at 2 and 6 weeks postoperatively. The secondary outcome was patient-reported postoperative pain using the Visual Analogue Scale (VAS) at 2 and 6 weeks postoperatively. A multivariable linear regression was used to analyse these outcomes with eight prognostic factors as independent variables. RESULTS: Tobacco usage was significantly associated with higher opioid usage at 2 (p < 0.001) and 6 weeks (p = 0.02) postoperatively. Former tobacco users had a higher 2-week (p = 0.002) and cumulative OME (p = 0.002) consumption compared to current and nonsmokers. Patients with a higher number of comorbidities (p = 0.006) and those who were employed (p = 0.006) reported higher pain scores at 6 weeks. Patients in the 'not employed/other' category had significantly lower pain scores at 6 weeks postoperatively (p = 0.046). CONCLUSION: Former smoking status was significantly associated with increased post-operative opioid consumption following knee and shoulder arthroscopy at 2 and 6 weeks postoperatively. Increased pain was found to be significantly associated with employment status and an increasing number of comorbidities at 6 weeks postoperatively. These findings can aid clinicians in identifying and mitigating increased opioid utilization as well as worse pain outcomes in high-risk patient populations. LEVEL OF EVIDENCE: Level III, cohort study.

Perioperative Management of Buprenorphine at an Urban Academic Medical Center.

INTRODUCTION: Buprenorphine is a partial mu opioid receptor agonist with high affinity to its receptor, which raises concerns of blocking or displacing full opioid agonists when used during the perioperative period of surgical patients. However, buprenorphine itself has high analgesic potency and discontinuing buprenorphine may lead to suboptimal pain control and risk for opioid use disorder relapse. There is limited data for the continuation of buprenorphine perioperatively. METHODS: This study is a retrospective cohort study of adult surgical patients taking buprenorphine for opioid use disorder at an urban, teaching, level 1 trauma center. Patients were split into two groups based on whether buprenorphine was continued (n = 46) or held (n = 28) within the first 48 h after surgery. RESULTS: Those who had buprenorphine continued in the first 48 h postoperatively required half the dose of nonbuprenorphine opioids compared to those who had buprenorphine held (113.25 versus 255.75 oral morphine equivalents, P = 0.0040). Both groups had a similar level of analgesia and incidence of adverse events. Nearly all patients who continued buprenorphine in the first 48 h postoperatively were discharged on this agent, while only half of patients who had buprenorphine held were restarted on it at discharge (92.68% versus 56.52%, P = 0.0013). CONCLUSIONS: This present study found lower nonbuprenorphine opioid requirements in patients with continued versus held perioperative buprenorphine use with no difference in degree of analgesia.

Procedural sedation and analgesia in Swiss Pediatric Emergency Departments: a national subgroup analysis of a European cross-sectional survey.

This study aims to provide a national overview of procedural sedation and analgesia practices within Pediatric Emergency Departments in Switzerland, focusing on the availability of pharmacologic agents, the presence of safety protocols, the utilization of non-pharmacological interventions, and to identify specific local limitations. We conducted a detailed subgroup analysis of Swiss data from a European cross-sectional survey on emergency department pediatric Procedural Sedation and Analgesia (PSA) practice, isolating data from Swiss sites. The survey, conducted between November 2019 and March 2020, covered various aspects of procedural sedation and analgesia practices. The survey included nine Swiss sites, treating a total of 252,786 patients in 2019. Topical analgesia, inhaled equimolar nitrous oxide-oxygen mixture, and ketamine were largely available. All sites had nurse-directed triage protocols in place; however, opioid administration was included in the protocols in only 66% of sites. Only 33% of hospitals reported common use of intravenous sedation. Barriers to procedural sedation and analgesia implementation included staffing shortages (89% of sites) and lack of dedicated spaces (78%).Conclusions: Despite a broad array of pharmacological and options available in Swiss Pediatric Emergency Departments, challenges remain in standardizing practices across the country. Limited space and staffing and enhancing training on non-pharmacological interventions were identified as potential areas for improving pain and anxiety management in pediatric emergency care. This study underscores the need for national guidelines to harmonize emergency department PSA practices across Switzerland, ensuring all children have access to effective and evidence-based procedural comfort. What is Known: • Recent research, conducted in European emergency departments, suggests that in pediatric Procedural Sedation and Analgesia (PSA) resources are limited, and practice is heterogeneous What is New: • Swiss pediatric hospitals offer a wide range of pharmacological options for pain and anxiety management. However, significant barriers to PSA were identified. These include external control of intravenous sedation and insufficient integration of non-pharmacological interventions, such as child life specialists and procedural hypnosis. National guidelines are needed to harmonize PSA practices.

Non-inferiority study assessing the utility of postcervical and lumbar radiofrequency ablation steroid use.

INTRODUCTION: Many physicians administer steroids after radiofrequency ablation (RFA) to mitigate postprocedural inflammation and decrease postprocedural pain. However, robust evidence supporting the benefits of steroids after RFA is lacking and steroids have risks. METHODS: This study was a single-center, prospective, observational study designed to assess whether RFA alone is inferior to RFA with steroids for postprocedure pain. Eligible patients were at least 18 years of age and scheduled to undergo cervical or lumbar RFA. The primary outcome measure was the average pain score on the numeric rating scale (NRS) 7 days after the RFA. The secondary outcome measures included anxiety, depression and physical function, measured via the Patient-Reported Outcomes Measurement Information System short forms. All outcome measures were completed prior to the procedure and at 7 and 60 days postprocedure. RESULTS: Out of the 365 participants who completed baseline assessments, 175 received steroids and 190 did not receive steroids. The pain intensity at 7 days postprocedure was similar between the steroid and non-steroid groups (mean difference (steroid-non-steroid): -0.23). The 95% CI of the estimate (-0.76 to 0.30) was within the prespecified non-inferiority margin of 1.5 NRS points. Similar results were obtained for pain at 60 days (mean difference: 0.09; 95% CI -0.48 to 0.65). No significant differences between groups were observed for anxiety, depression or physical function at either 7 or 60 days. CONCLUSION: This study suggests that the addition of steroids to the RFA procedure does not provide added benefits and is therefore not worth the additional risks that they pose.

The Fontan Circulation in Pregnancy: Hemodynamic Challenges and Anesthetic Considerations.

Pregnancy in patients with Fontan physiology presents unique challenges due to altered cardiovascular dynamics inherent to both conditions. The Fontan procedure reroutes venous blood directly to the pulmonary arteries, bypassing the heart, and necessitating precise regulation of pulmonary venous resistance and systemic venous pressure to maintain effective cardiac output. The significant cardiovascular adaptations required during pregnancy to meet the metabolic demands of the mother and fetus can overburden the limited preload capacity and venous compliance in Fontan patients, predisposing them to a spectrum of potential complications, including arrhythmias, heart failure, thromboembolism, and obstetric and fetal risks. This review delineates the essential physiological adaptations during pregnancy and the challenges faced by Fontan patients, advocating for a comprehensive care approach involving multidisciplinary collaboration, vigilant monitoring, tailored anesthetic management, and postpartum care. Understanding the complex dynamics between Fontan physiology and pregnancy is crucial for anesthesiologists to develop and execute individualized management strategies to minimize risks and optimize outcomes for this high-risk population.

Predicting postoperative pain in children: an observational study using the pain threshold Index.

Objective: While the pain threshold index (PTI) holds potential as a tool for monitoring analgesia-pain equilibrium, its precision in forecasting postoperative pain in children remains unconfirmed. This study's primary aim was to assess the PTI's predictive precision for postoperative pain. Methods: Children (aged 2-16 years) undergoing general surgery under general anesthesia were included. Within 5 min prior to the patient's emergence from surgery, data including PTI, wavelet index (WLI), heart rates (HR) and mean arterial pressure (MAP) were collected. Subsequently, a 15-min pain assessment was conducted following the patient's awakening. The accuracy of these indicators in discerning between mild and moderate to severe postoperative pain was evaluated through receiver operating characteristic (ROC) analysis. Results: The analysis encompassed data from 90 children. ROC analysis showed that PTI was slightly better than HR, MAP and WLI in predicting postoperative pain, but its predictive value was limited. The area under the curve (AUC) was 0.659 [0.537∼0.780] and the optimal threshold was 65[64-67]. Sensitivity and specificity were determined at 0.90 and 0.50, respectively. In a multivariable logistic regression model, a higher predictive accuracy was found for a multivariable predictor combining PTI values with gender, BMI, HR and MAP (AUC, 0.768; 95%CI, 0.669-0.866). Upon further scrutinizing the age groups, PTI's AUC was 0.796 for children aged 9-16, 0.656 for those aged 4-8, and 0.601 for younger individuals. Conclusions: PTI, when used alone, lacks acceptable accuracy in predicting postoperative pain in children aged 2 to 16 years. However, when combined with other factors, it shows improved predictive accuracy. Notably, PTI appears to be more accurate in older children.

Continuous Ultrasound-Guided Lumbar Erector Spinae Plane Block for Thigh Cellulitis Analgesia: A Case Report.

The management of refractory acute medical pain can be challenging, especially if severe and decompensated systemic pathologies contraindicate neuraxial techniques and deep peripheral blocks. In this case report, we propose a continuous ultrasound-guided lumbar erector spinae plane block (ESPB) for multimodal analgesia of thigh cellulitis. The patient was an 80-year-old male, admitted to the intensive care unit due to septic shock originating from cellulitis of the right lower limb, associated with multiorgan dysfunction. To address refractory pain in the thigh, an ultrasound-guided lumbar ESPB at L3 was performed, with the placement of a perineural catheter and administration of 30 mL of 0.5% ropivacaine, followed by 30 mL boluses of 0.375% ropivacaine every six hours with progressive weaning. The patient maintained controlled pain without the need for rescue analgesia. Continuous ultrasound-guided lumbar ESPB is an effective and safe alternative for thigh analgesia in patients with refractory acute medical pain and systemic pathologies that contraindicate other regional techniques.

Predictive value of neutrophil-to-lymphocyte ratio on admission for intrapartum maternal fever in parturients undergoing epidural analgesia: A retrospective cohort study using propensity score-matched analysis.

OBJECTIVE: To identify the predictive value of the neutrophil-to-lymphocyte ratio (NLR) on admission for intrapartum maternal fever in parturients undergoing epidural analgesia (EA). METHODS: In this retrospective cohort study, propensity score matching (PSM) was applied to address covariates. Univariate and multivariate regression analyses were implemented in sequence to find out the factors influencing intrapartum fever. The receiver operating characteristics curve was applied to determine the area under the curve (AUC) of NLR for intrapartum fever. RESULTS: NLR and duration of EA were independent risk factors for intrapartum fever. The AUC of the combined indicator (NLR + duration of EA) was higher than that of NLR (AUC = 0.583, 95% confidence interval [CI] 0.53-0.64) and duration of EA (AUC = 0.702, 95% CI 0.66-0.75), reaching 0.715 (95% CI 0.67-0.76; p < 0.001). NLR increased predictive performance for intrapartum fever when added to the duration of EA (net reclassification index 0.076, p = 0.022; integrated discrimination improvement 0.020, p = 0.002). CONCLUSION: NLR has limited predictive power for intrapartum fever. The combination of NLR and duration of epidural analgesia may be considered a promising predictor for intrapartum maternal fever in parturients undergoing epidural analgesia. SYNOPSIS: The neutrophil-to-lymphocyte ratio is an accessible predictor for the early identification of parturients at risk of intrapartum fever.

Retrospective review of surgeon administered transversus abdominis plane blocks at emergency caesarean.

BACKGROUND: Effective analgesics with minimal side effects are imperative for patient and neonate wellbeing postpartum. Post-caesarean section ultrasound-guided transversus abdominis plane (TAP) blocks have proven safety and efficacy. Surgical TAP blocks appear effective and require little time and equipment. No previous examination of surgical TAP blocks in patients having undergone emergency caesarean section has been undertaken. AIMS: To investigate surgical TAP block and multimodal analgesic use during emergency caesarean section, the effect on surgical time, post-operative analgesia use, and admission length. MATERIALS AND METHODS: We performed a retrospective review of 250 patients who underwent emergency caesarean in 2022. Surgical TAP blocks were performed with 20 mL of 0.375% ropivacaine either side. Primary outcomes included surgical time, length of admission, time to first request of rescue opiate, opiate use in first post-operative 24 h, total dose used during admission, and opiates prescribed on discharge. RESULTS: Ninety-six patients received surgical TAP blocks, and 154 did not. There were no statistically significant differences in the primary outcomes. Subgroup analyses were performed in patients who did not receive intrathecal morphine, body mass index over 30 kg/m2, for patients whom this was their first caesarean, and for TAP blocks versus local infiltration to the wound. There were no significant differences in the primary outcomes in these subgroups. CONCLUSIONS: Surgical TAP blocks did not prolong surgical time or decrease post-operative analgesia use or admission length in patients having undergone emergency caesarean. Patient-tailored multimodal analgesia is encouraged, although more research is needed.

Comparative analysis of contrast distribution in cervical epidural steroid injections utilizing a modified paramedian interlaminar approach with varied needle tip positions: A randomized controlled trial.

BACKGROUND: Recent advancements in cervical interlaminar epidural steroid injections have given rise to the modified paramedian interlaminar (mPIL) approach. The objective of this study was to perform an analysis of the contrast spread pattern within the cervical epidural space, taking into account different needle tip positions in the mPIL approach. METHODS: A total of 48 patients were included in the study and randomly assigned to either the medial or lateral group based on the needle tip's position in the anterior-posterior view. The primary outcome measured was the contrast flow under fluoroscopic visualization. As a secondary outcome, we analyzed the location of the needle tip position in both lateral and contralateral oblique views. Clinical effectiveness was assessed by measuring pain intensity and functional disability post-procedure. RESULTS: Significant disparities were noted in the ventral distribution of contrast between the medial and lateral groups. In the lateral images, needle tips in the lateral group were positioned more ventrally compared to those in the medial group. Both groups exhibited statistically significant improvements in neck and radicular pain, as well as functional status, 4 weeks after treatment, with no significant differences between them. CONCLUSIONS: Our results suggest that the ventral dispersion of contrast material during cervical interlaminar epidural steroid injections using the mPIL approach may vary depending on the needle tip location.

Peripheral nerve stimulation (PNS) of the phrenic nerve for intractable hiccups: a novel use case report.

BACKGROUND: Intractable hiccups, defined as those persisting for over 1 month, represent a rare but significant clinical challenge often associated with substantial morbidity and refractory to standard treatments. CASE PRESENTATION: This case report describes the innovative use of phrenic nerve peripheral neuromodulation for managing chronic intractable hiccups in a 73-year-old male patient with a 6-year history of daily hiccups. Conventional treatments and interventional procedures had failed to provide lasting relief. Bilateral phrenic nerve peripheral nerve stimulation (PNS) placed under ultrasound guidance resulted in immediate and substantial improvement, with the patient's Hiccup Assessment Instrument score decreasing from 6/10 to 2/10. The patient experienced significant enhancements in speech and quality of life without complications. CONCLUSIONS: This novel application of phrenic nerve PNS highlights its potential as a therapeutic strategy for intractable hiccups, underscoring their pathophysiologic involvement of the diaphragm and respiratory muscles. The findings suggest that phrenic nerve PNS could offer a viable treatment option for patients unresponsive to conventional therapies, warranting further research to establish its long-term efficacy and safety.

[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.
