RESUMEN
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.
RESUMEN
Objective The objective of this study was to assess the feasibility of using an intracameral phenylephrine/ketorolac infusion during cataract surgery as a single agent to prevent postoperative pain, inflammation, and other complications. Methods A prospective, single-group feasibility study was conducted in which phenylephrine/ketorolac infusion was administered during cataract surgery and no perioperative topical drops were initially prescribed. Patients underwent optical coherence tomography, corrected distance visual acuity testing, and slit lamp biomicroscopy examination at perioperative visits, during which they also reported symptoms of pain, irritation, and/or photophobia. A goal adverse event (AE) rate was set at ≤5.0%. Results A total of 94 eyes (60 patients) were included in this study. The AE rate was 13.8% (13/94 eyes) with pain/irritation in eight eyes, cystoid macular edema (CME) in three eyes, and corneal edema in three eyes. Conclusions Based on an AE rate goal of ≤5.0%, using intraoperative, intracameral phenylephrine/ketorolac alone was not deemed a feasible alternative to current postoperative eye drop regimens in our clinical setting. However, a 13.8% AE rate is comparable to the rates of postoperative CME, corneal edema, pain, and irritation in the published literature. Thus, more research is needed to truly define this approach as inferior or non-inferior to the current standard of care.
RESUMEN
OBJECTIVE: it was to explore the influence of the postoperative pain management mode on the psychological state, quality of life (QOL), and nursing satisfaction of late patients in the intensive care unit (ICU) and improve the nursing effect of late patients in the ICU. METHODS: seventy patients who were admitted to the postoperative ICU for gastric cancer and received treatment in our hospital from March 2021 to May 2022 were selected. The patients were assigned into a research group and a control (Ctrl) group according to a random number table, with 70 cases in each group. The Ctrl group received routine nursing intervention, while research group received nursing intervention based on routine nursing intervention with postoperative pain management mode and received psychological care. Good communication was established with the patients, and the postoperative pain assessment was well conducted. The general information, state-trait anxiety (STAI) score, World Health Organization's Quality of Life Instrument (WHO QOL-BREF) score, and care satisfaction were compared. RESULTS: the general information differed slightly, such as sex, age, and ward type, between groups, with comparability (P > 0.05). S-AI scores (13.15 ± 1.53 vs. 16.23 ± 1.24) and T-AI scores (14.73 ± 3.12 vs. 18.73 ± 3.16) in research group were inferior to those in Ctrl group (P < 0.05). The scores of patients in research group in the physiological field (78.9 ± 6.1 points vs. 72.3 ± 5.6 points), social relationship field (76.9 ± 4.5 points vs. 71.3 ± 4.8 points), psychological field (78.6 ± 6.2 points vs. 72.4 ± 5.3 points), environmental field (78.6 ± 6.7 points vs. 73.5 ± 6.4 points), and total QOL (79.5 ± 7.4 points vs. 71.6 ± 5.4 points) were higher than those in Ctrl group (P < 0.05). The total satisfaction rate with nursing care in research group (82.85%) was dramatically superior to that in Ctrl group (62.85%) (P < 0.05). CONCLUSION: the adoption of a postoperative pain management model in postoperative nursing interventions for patients in advanced ICUs can alleviate anxiety and depression, improve patients' QOL and nursing satisfaction, and have clinical promotion value.
RESUMEN
Enhanced Recovery After Surgery (ERAS) protocols have substantially proven their merit in diminishing recuperation durations and mitigating postoperative adverse events in geriatric populations undergoing colorectal cancer procedures. Despite this, the pivotal aspect of postoperative pain control has not garnered the commensurate attention it deserves. Typically, employing a multimodal analgesia regimen that weaves together nonsteroidal anti-inflammatory drugs, opioids, local anesthetics, and nerve blocks stands paramount in curtailing surgical complications and facilitating reduced convalescence within hospital confines. Nevertheless, this integrative pain strategy is not devoid of pitfalls; the specter of organ dysfunction looms over the geriatric cohort, rooted in the abuse of analgesics or the complex interplay of polypharmacy. Revolutionary research is delving into alternative delivery and release modalities, seeking to allay the inadvertent consequences of analgesia and thereby potentially elevating postoperative outcomes for the elderly post-colorectal cancer surgery populace. This review examines the dual aspects of multimodal analgesia regimens by comparing their established benefits with potential limitations and offers insight into the evolving strategies of drug administration and release.
RESUMEN
Postoperative pain management following spine surgery remains a significant challenge, often requiring multimodal approaches to achieve adequate analgesia while minimizing side effects. The thoracolumbar interfascial plane (TLIP) block has emerged as a novel regional anesthesia technique for addressing this issue. By targeting the interfascial plane between the erector spinae and quadratus lumborum muscles at the thoracolumbar junction, the TLIP block aims to provide targeted analgesia to the surgical site while reducing systemic opioid requirements. This review explores the anatomy, technique, mechanism of action, and clinical evidence supporting the TLIP block for post-spine surgery pain management. Additionally, it compares the TLIP block with traditional pain management approaches and discusses its implications for clinical practice and future research. Overall, the TLIP block shows promise as an effective and potentially safer alternative for post-spine surgery pain management, potentially improving patient outcomes and enhancing recovery. Further research is warranted to optimize its utilization and comprehensively evaluate its long-term effects.
RESUMEN
Opioids are powerful analgesics; however, their significant systemic adverse effects and the need for frequent administration restrict their use. Nalbuphine (NA) is a κ-agonist narcotic with limited adverse effects, but needs to be frequently administrated due to its short elimination half-life. Whereas sebacoyl dinalbuphine ester (SDE) is a NA prodrug, which can effectively prolong the analgesic effect, but lacks immediate pain relief. Therefore, in this study, a rapid and sustained local delivery formulation to introduce NA and SDE directly into surgical sites was developed. An amphiphilic nanostructured lipid carrier (NLC) poloxamer 407 (P407) gel (NLC-Gel) was developed to permit concurrent delivery of hydrophobic SDE from the NLC core and hydrophilic NA from P407, offering a dual rapid and prolonged analgesic effect. Benefiting from the thermal-sensitive characteristic of P407, the formulation can be injected in liquid phase and instantly transit into gel at wound site. NLC-Gel properties, including particle size, drug release, rheology, and stability, were assessed. In vivo evaluation using a rat spinal surgery model highlighted the effect of the formulation through pain behavior test and hematology analysis. NLC-Gels demonstrated an analgesic effect comparable with that of commercial intramuscular injected SDE formulation (IM SDE), with only 15 % of the drug dosage. The inclusion of supplemental NA in the exterior gel (PA12-Gel + NA) provided rapid drug onset owing to swift NA dispersion, addressing acute pain within hours along with prolonged analgesic effects. Our findings suggest that this amphiphilic formulation significantly enhanced postoperative pain management in terms of safety and efficacy.

BACKGROUND: Approximately 38,000 scoliosis surgery correction operations are performed annually in the United States; these operations are associated with considerable postoperative pain which can be difficult to manage. This is largely attributed to an incision spanning multiple vertebral segments with paraspinal muscle dissection and retraction to facilitate the implantation of segmental hardware and rods. Frequently utilized analgesic modalities include intravenous patient-controlled analgesia and epidural analgesia, often in combination. We sought to ascertain the feasibility and analgesic efficacy of continuous thoracolumbar dorsal ramus nerve (TDRN) block using surgically placed multiorifice catheters. METHODS: Forty-two patients diagnosed with idiopathic scoliosis who underwent a posterior spinal fusion (PSF) were enrolled after consent was obtained. Patients were managed utilizing a standardized Enhanced Recovery After Surgery) protocol including a perioperative opioid-sparing regimen. Data were collected at specified time intervals during the recovery period. These data points included pain scores using the Numeric Rating Scale. Parenteral or both oral and parenteral opioid consumption doses were also collected every 4 hours. Any significant postoperative adverse events were recorded as well. RESULTS: A total of 42 patients had surgically placed TDRN catheters, and 40 patients were included in this study. The patients all reported low to moderate pain scores with low opioid consumption postoperatively, while the TDRN catheter delivery of local anesthetic analgesics did not result in significant complications. CLINICAL RELEVANCE: A regional technique utilizing TDRN catheters could be a valuable component of the postoperative pain management protocols for PSF surgery, and additional studies are warranted. CONCLUSION: This study evaluated the feasibility and analgesic efficacy of TDRN catheters for postoperative pain control following multilevel PSF for idiopathic scoliosis. Continuous local anesthetic delivery through TDRN catheters is a feasible and safe technique for postoperative pain control in these patients. Selective blockade of the dorsal rami might have benefits over epidural analgesia or other regional techniques.
RESUMEN
BACKGROUND: Current evidence supports that many patients do not use prescribed opioids following reconstructive pelvic surgery, yet it remains unclear if it is feasible to eliminate routine opioid prescriptions without a negative impact on patients or providers. OBJECTIVE: To determine if there is a difference in the proportion of patients discharged without opioids after implementing a bundle of opioid-sparing strategies and tiered prescribing protocol compared to usual care after minimally invasive pelvic reconstructive surgery (transvaginal, laparoscopic, or robotic). Secondary objectives include measures of patient-perceived pain control and provider workload. STUDY DESIGN: The bundle of opioid-sparing strategies and tiered prescribing protocol intervention was implemented as a division-wide evidence-based practice change on August 1, 2022. This retrospective cohort compares a 6-month postintervention (bundle of opioid-sparing strategies and tiered prescribing protocol) cohort to 6-month preintervention (usual care) of patients undergoing minimally invasive pelvic reconstructive surgery. A 3-month washout period was observed after bundle of opioid-sparing strategies and tiered prescribing protocol initiation. We excluded patients <18 years, failure to consent to research, combined surgery with other specialties, urge urinary incontinence or urinary retention procedures alone, and minor procedures not typically requiring opioids. Primary outcome was measured by proportion discharged without opioids and total oral morphine equivalents prescribed. Pain control was measured by pain scores, postdischarge prescriptions and refills, phone calls and visits related to pain, and satisfaction with pain control. Provider workload was demonstrated by phone calls and postdischarge prescription refills. Data were obtained through chart review on all patients who met inclusion criteria. Primary analysis only included patients prescribed opioids according to the bundle of opioid-sparing strategies and tiered prescribing protocol protocol. Two sample t tests compared continuous variables and chi-square tests compared categorical variables. RESULTS: Four hundred sixteen patients were included in the primary analysis (207 bundle of opioid-sparing strategies and tiered prescribing protocol, 209 usual care). Baseline demographics were similar between groups, except a lower proportion of irritable bowel syndrome (13% vs 23%; P<.01) and pelvic pain (15% vs 24.9%; P=.01), and higher history of prior gynecologic surgery (69.1% vs 58.4%; P=.02) in the bundle of opioid-sparing strategies and tiered prescribing protocol cohort. The bundle of opioid-sparing strategies and tiered prescribing protocol cohort was more likely to be discharged without opioids (68.1% vs 10.0%; P<.01). In those prescribed opioids, total oral morphine equivalents on discharge was significantly lower in the bundle of opioid-sparing strategies and tiered prescribing protocol cohort (48.1 vs 81.8; P<.01). The bundle of opioid-sparing strategies and tiered prescribing protocol cohort had a 20.6 greater odds (confidence interval 11.4, 37.1) of being discharged without opioids after adjusting for surgery type, arthritis/joint pain, IBS, pelvic pain, and contraindication to nonsteroidal anti-inflammatory drugs. The bundle of opioid-sparing strategies and tiered prescribing protocol cohort was also less likely to receive a rescue opioid prescription after discharge (1.4% vs 9.5%; P=.03). There were no differences in opioid prescription refills (19.7% vs 18.1%; P=.77), emergency room visits for pain (3.4% vs 2.9%; P=.76), postoperative pain scores (mean 4.7 vs 4.0; P=.07), or patient satisfaction with pain control (81.5% vs 85.6%; P=.21). After bundle of opioid-sparing strategies and tiered prescribing protocol implementation, the proportion of postoperative phone calls for pain also decreased (12.6% vs 21.5%; P=.02). Similar results were identified when nonadherent prescribing was included in the analysis. CONCLUSION: A bundle of evidence-based opioid sparing strategies and tiered prescribing based on inpatient use increases the proportion of patients discharged without opioids after minimally invasive pelvic reconstructive surgery without evidence of uncontrolled pain or increased provider workload.

Total knee replacement, a common surgery among the elderly primarily necessitated by osteoarthritis, replaces the damaged knee joint with an artificial one. Given the aging population and the increasing prevalence of such surgeries, the article highlights the critical need for effective postoperative care strategies. This editorial provides an overview of rehabilitation care for pain in elderly knee replacement patients, emphasizing the importance of a multimodal approach to postoperative recovery. Furthermore, the article advocates for a patient-centered, comprehensive rehabilitation regimen that enhances recovery and quality of life in elderly patients undergoing knee replacement surgery.
RESUMEN
Epidural catheters are seldom challenging to remove from patients. The occurrence of knotting in an epidural catheter, resulting in entrapment, is an uncommon complication of epidural catheterization. There is the risk of significant morbidity with a retained catheter, with the potential for infection or nerve injury. This report describes the techniques used in a case where surgical removal of an entrapped epidural was required and discusses other potential strategies for the successful management of this type of complication. In this case, a low thoracic epidural catheter that was inserted into a 68-year-old male for post-operative analgesia proved challenging to remove. After multiple attempts to remove the catheter, a lumbar CT scan and neurosurgical evaluation were obtained. The neurosurgical team decided to perform a right thoracic hemilaminectomy to remove the entrapped catheter. This surgery revealed a knot near the distal tip of the catheter, which likely caused the entrapment of the catheter in the epidural space.
RESUMEN
BACKGROUND CONTEXT: Postoperative pain control following spine surgery can be difficult. The Enhanced Recovery After Surgery (ERAS) programs use multimodal approaches to manage postoperative pain. While an erector spinae plane block (ESPB) is commonly utilized, the ideal distance for injection from the incision, referred to as the ES (ESPB to mid-surgical level) distance, remains undetermined. PURPOSE: We evaluated the impact of varying ES distances for ESPB on Numerical Rating Scale (NRS) measures of postoperative pain within the ERAS protocol. STUDY DESIGN/SETTING: Retrospective observational study. PATIENT SAMPLE: Adult patients who underwent elective lumbar spine fusion surgery. OUTCOME MEASURES: Primary outcome measures include the comparative postoperative NRS scores across groups at immediate (T1), 24 (T2), 48 (T3), and 72 (T4) hours postsurgery. For secondary outcomes, a propensity matching analysis compared these outcomes between the ERAS and non-ERAS groups, with opioid-related recovery metrics also assessed. METHODS: All included patients were assigned to one of three ERAS groups according to the ES distance: Group 1 (G1, ES > 3 segments), Group 2 (G2, ES = 2-3 segments), and Group 3 (G3, ES<2 segments). Each patient underwent a bilateral ultrasound-guided ESPB with 60 mL of diluted ropivacaine or bupivacaine. RESULTS: Patients within the ERAS cohort reported mild pain (NRS < 3), with no significant NRS variation across G1 to G3 at any time. Sixty-five patients were matched across ERAS and non-ERAS groups. The ERAS group exhibited significantly lower NRS scores from T1 to T3 than the non-ERAS group. Total morphine consumption during hospitalization was 26.7 mg for ERAS and 41.5 mg for non-ERAS patients. The ERAS group resumed water and food intake sooner and had less postoperative nausea and vomiting. CONCLUSIONS: ESPBs can be effectively administered at or near the mid-surgical level to the low thoracic region for lumbar spine surgeries. Given challenges with sonovisualization, a lumbar ESPB may be preferred to minimize the risk of inadvertent pleural injury.

Optimal pain relief in day-case surgery is imperative to patient comfort and timely discharge from hospital. Short-acting opioids are commonly used for analgesia in modern anaesthesia, allowing rapid recovery after surgery. Plasma concentration fluctuations from repeated dosing of short-acting opioids can cause patients to oscillate between analgesia with potential adverse effects, and inadequate analgesia requiring rescue dosing. Methadone's unique pharmacology may offer effective and sustained analgesia with less opioid consumption, potentially reducing adverse effects. Using a double-blind, randomised controlled trial, we compared post-anaesthesia care unit opioid consumption between day-case gynaecological laparoscopy patients who received either intravenous methadone (10 mg), or short-acting opioids intraoperatively. The primary outcome was post-anaesthesia care unit opioid consumption in oral morphine equivalents. Secondary outcomes included total opioid consumption, discharge opioid consumption, pain scores (0-10) until discharge, adverse effects (respiratory depression, postoperative nausea and vomiting, excess sedation), and rate of admission. Seventy patients were randomly assigned. Patients who received methadone consumed on average 9.44 mg fewer oral morphine equivalents in the post-anaesthesia care unit than the short-acting group (18.02 mg vs 27.46 mg, respectively, 95% confidence interval 0.003 to 18.88, P = 0.050) and experienced lower postoperative pain scores at every time point, although absolute differences were small. There was no evidence of lower hospital or discharge opioid consumption. No significant differences between the methadone and short-acting groups in other outcomes were identified: respiratory depression 41.2% versus 31.4%, Padjusted >0.99; postoperative nausea and vomiting 29.4% versus 42.9%, Padjusted >0.99; overnight admission 17.7% versus 11.4%, Padjusted >0.99; excess sedation 8.82% versus 8.57%, Padjusted >0.99. This study provides evidence that, although modestly, methadone can reduce post-anaesthesia care unit opioid consumption and postoperative pain scores after day-case gynaecological laparoscopy. There were no significant differences in any secondary outcomes.

BACKGROUND: Postoperative pain management in lumbar spine surgery care remains a challenge. The aim of this study was to evaluate the impact of a person-centred postoperative pain management intervention programme on lumbar spine surgery patients on postoperative pain, shared decision-making, and satisfaction with postoperative pain management. METHODS: The study was performed with a controlled before-and-after interventional design in an orthopaedic unit at a university hospital. Person-centred pain management for patients undergoing spine surgery was developed in co-creation by a multi-professional team and implemented throughout the care pathway. The usual care group (pre-intervention) served as a comparison to the intervention group. Pain intensity, shared decision-making in pain management, and patient satisfaction with results of pain management, served as patient-reported measures, collected using the International Pain Outcomes questionnaire and analysed using descriptive statistics. RESULTS: The intervention showed no benefit for patients' pain and satisfaction, while shared decision-making in pain management was significant lower in the intervention group than in the conventional group. The per-protocol analysis showed no significant differences between groups. CONCLUSION: The initial assumption of the study, that the implementation of a co-created structured person-centred care pathway would improve patient-reported outcomes, was not confirmed. The periodically low fidelity to the intervention due to organizational constraints (due to sub-optimal organizational conditions and managerial support) may have affected the results.

BACKGROUND: Morphine-sparing effects are often used to evaluate non-opioid analgesic interventions. The exact effect that would warrant the implementation of these interventions in clinical practice (a minimally important difference) remains unclear. We aimed to determine this with anchor-based methods. METHODS: This was a post hoc analysis of three studies investigating pain management after hip or knee arthroplasty (PANSAID [NCT02571361], DEX-2-TKA [NCT03506789] and Pain Map [NCT02340052]). The overall population was median aged 70, median ASA 2, 54% female. We examined the correlation between 0 and 24 h postoperative iv morphine equivalent consumption and the severity of nausea, vomiting, sedation and dizziness. The anchor was different severity degrees of these opioid-related adverse events. The primary outcome was the difference in morphine consumption between patients experiencing no versus only mild events. Secondary outcomes included the difference in morphine consumption between patients with mild versus moderate and moderate versus severe events. We used Hodges-Lehmann median differences, exact Wilcoxon-Mann-Whitney tests and quantile regression. RESULTS: The difference in iv morphine consumption was 6 mg (95% confidence interval: 4-8) between patients with no versus only mild events, 5 mg (2-8) between patients with mild versus moderate events and 0 mg (-4 to 4) between patients with moderate versus severe events. CONCLUSIONS: In populations comparable to this post-hoc analysis (orthopaedic surgery, median age 70 and ASA 2), we suggest a minimally important difference of 5 mg for 0-24 h postoperative iv morphine consumption.

BACKGROUND: Multiple medications are more effective than single agents for postoperative pain management. We investigated the analgesic effects of an intravenous combination of acetaminophen and ibuprofen immediately after thyroidectomy. METHODS: In this double-blind clinical trial, 62 patients who underwent thyroidectomies were randomized to either the treatment (1000 mg acetaminophen, 300 mg ibuprofen) or control (1000 mg acetaminophen) group. Postoperative pain intensity was assessed using the visual analog scale (VAS) 0, 15, and 30 min after recovery room admission. Opioid rescue consumption was also recorded. RESULTS: The VAS scores were significantly lower in the treatment than in the control group 15 [3 (2-4.3) vs. 5 (3-6); p = 0.015] and 30 [3 (2-4.3) vs. 4 (3-5); p = 0.018] min after recovery room admission, as were the opioid rescue dose requirements (p = 0.033). CONCLUSIONS: Combined intravenous acetaminophen and ibuprofen may be better than acetaminophen alone for immediately acute postoperative pain after thyroidectomy.

Total knee arthroplasty (TKA) often involves significant postoperative pain, necessitating effective analgesia. This meta-analysis compares the analgesic efficacy of local infiltration anaesthesia (LIA) and femoral nerve block (FNB) in managing postoperative wound pain following TKA. Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this meta-analysis was structured around the PICO framework, assessing studies that directly compared LIA and FNB in TKA patients. A comprehensive search across PubMed, Embase, Web of Science and the Cochrane Library was conducted without time restrictions. Studies were included based on specific criteria such as participant demographics, study design and outcomes like pain scores and opioid consumption. Quality assessment utilized the Cochrane Collaboration's risk of bias tool. The statistical approach was determined based on heterogeneity, with the choice of fixed- or random-effects models guided by the I2 statistic. Sensitivity analysis and evaluation of publication bias using funnel plots and Egger's linear regression test were also conducted. From an initial pool of 1275 articles, eight studies met the inclusion criteria. These studies conducted in various countries from 2007 to 2016. The meta-analysis showed no significant difference in resting and movement-related Visual Analogue Scale scores post-TKA between the LIA and FNB groups. However, LIA was associated with significantly lower opioid consumption. The quality assessment revealed a low risk of bias in most studies, and the sensitivity analysis confirmed the stability of these findings. There was no significant publication bias detected. Both LIA and FNB are effective in controlling postoperative pain in TKA patients, but LIA offers the advantage of lower opioid consumption. Its simplicity, cost-effectiveness and opioid-sparing nature make LIA the recommended choice for postoperative analgesia in knee replacement surgeries.

Antler removal in deer is a common practice for various purposes, including meat production and traditional medicine. However, the current industry practice using lidocaine as a local anesthetic has limitations, such as short duration of action and the potential for postoperative infections. In this study, we investigated the performance of a ZnO collagen nanocomposites loaded with local anesthetics to improve wound management and alleviate pain associated with antler removal in red deer. The research involved the preparation of collagen nanocomposites with local anesthetics and testing the drug release rates using in vitro drug release tests. Pharmacokinetic analysis was performed to evaluate the total drug release from the collagen matrix in red deer after velvet removal. Additionally, the analgesic efficacy of these collagen nanocomposite dressings was assessed after antler removal in red deer. Functionalized ZnO nanoparticles were incorporated into collagen fibers to enhance their mechanical stability and prolong drug release. The developed collagen nanocomposites aimed to slowly release local anesthetics and promote wound healing. The findings of this research could have significant implications for improving the pain management and wound healing associated with antler removal in deer. The results obtained from the in vitro drug release tests, pharmacokinetic analysis, and analgesic efficacy evaluations provide valuable insights into the understanding and development of novel approaches for antler removal procedures in red deer. The findings contribute to the advancement of knowledge in this field and lay the foundation for future implementation of improved techniques and protocols for antler removal.

Background: To investigate if combined single-shot adductor canal blockade (ACB) and inï¬ltration between the popliteal artery and capsule of the knee (IPACK) provide better postoperative pain management compared to ACB alone for patients undergoing unilateral total knee arthroplasty (TKA). Methods: This retrospective cohort study included adult patients who underwent primary, unilateral TKA. Patients were separated into 2 cohorts: single-shot ACB alone (performed with bupivacaine 0.25%) and combined single-shot ACB + IPACK (performed with bupivacaine 0.25%, dexmedetomidine 1 mg/kg, and dexamethasone 4 mg). Patients were propensity-matched 1:1. The primary study outcome was total opioid consumption converted to morphine milligram equivalents (MME) per eight-hour interval and postoperative day. Secondary outcomes included pain scores, length of stay, ambulation distance, return to emergency department, hospital readmission, and 30-day adverse events. Results: One hundred eighty patients were identified, of which propensity matching used 71% to yield 64 patients receiving ACB alone and 64 receiving combined ACB + IPACK. Combined ACB + IPACK had significantly lower total summative MME throughout the entire postoperative stay (P = .002) and cumulatively after the first 24 hours (P < .001). Combined ACB + IPACK also had lower mean pain scores for 0-8 hours (P = .005) and 8-16 hours (P = .009) postoperatively. There were no significant differences in secondary outcomes. Conclusions: Combined single-shot ACB + IPACK block was associated with lower total narcotic intake and mean pain scores during most of the immediate postoperative period following primary, unilateral TKA compared to ACB alone. Implementing longer-acting, single-shot ACB + IPACK for TKA can balance effective and more selective pain management with early rehabilitation.
RESUMEN
BACKGROUND AND OBJECTIVES: Due to frailty, dermatosurgery in the elderly is preferably performed under tumescent local anesthesia, but data is limited. The aim was to evaluate tumescent local anesthesia for skin cancer surgery in the elderly with focus on clinical benefits (treatment processes, pain management) and local postoperative complication risk. PATIENTS AND METHODS: Investigation of patients ≥ 75 years with inpatient head and neck skin cancer surgery under tumescent local anesthesia. RESULTS: 2,940 procedures in 782 patients (mean age 83.3 years) were performed with the aim of complete tumor resection during the inpatient stay. 3.8 (range: 1-20) interventions were done over an average of 4.9 days (range: 1-28). 43.2% did not require any postoperative analgesia. 53.5% received NSAIDs, 3.3% opioids. Infection (13.6%) was the most common local postoperative complication. Surgical intervention due to bleeding was required in 2.8%. None was hemoglobin relevant or life-threatening. Suture dehiscence and necrosis were rare (0.6%). CONCLUSIONS: Tumescent local anesthesia is an effective method for skin cancer surgery in the elderly. By avoiding general anesthesia, treatment processes can be optimized and anesthesiologic risks minimized. Local postoperative complications are still low and well treatable. The long-lasting analgesia results in a reduced need for analgesics and drug interactions.

PURPOSE: Our institution employs a multimodal approach to manage postoperative pain after spine surgery. It involves continuous intravenous (IV) lidocaine until the morning of postoperative day two. This study aimed to determine the rate and reasons for early discontinuation of IV lidocaine in our spine patients. METHODS: We conducted a retrospective chart review and included pediatric patients who underwent ≥ 3-level spine surgery and received postoperative IV lidocaine from November 2019 to September 2022. For each case, we recorded the side effects of IV lidocaine, adverse events, time to discontinuation, and discontinuation rate. Subsequently, we used the same methodology to generate an adult cohort for comparison. RESULTS: We included 52 pediatric (18M:34F) and 50 (21M:29F) adult patients. The pediatric cohort's mean age was 14 years (8-18), and BMI 23.9 kg/m2 (13.0-42.8). The adult cohort's mean age was 61 years (29-82), and BMI 28.8 kg/m2 (17.2-44.1). IV lidocaine was discontinued prematurely in 21/52 (40.4%) of the pediatric cases and 26/50 (52.0%) of the adult cases (RR = 0.78, p = 0.2428). The side effects noted in the pediatric cases vary, including numbness, visual disturbance, and obtundation, but no seizures. The most common adverse events were fever and motor dysfunction. CONCLUSION: The early discontinuation rate of IV lidocaine use after spine surgery for children in our institution does not differ significantly from that of adults. The nature of the side effects and the reasons for discontinuation between the groups were similar. Thus, the safety profile of IV lidocaine for pediatric spine patients is comparable to adults.
