Successful use of ultrasound guided pecto-intercostal fascial plane block to provide intraoperative analgesia in four dogs undergoing median sternotomy.

To evaluate the impact of pecto-intercostal fascial plane block on providing intraoperative analgesia in dogs undergoing median sternotomy. 4 dogs. The dogs were presented with a history of inappetence, lethargy and respiratory distress. Thoracic radiographs, point of care ultrasound, thoracocentesis, bronchoscopy and computed tomography was performed to characterize the disease. 4 male castrated, 5.3 ± 3 years old dogs weighing 19.7 ± 13.5 kg and belonging to Dalmatian, Beagle, Siberian Husky and Rottweiler breeds were included. Three dogs were diagnosed with suppurative pleural effusions because of pulmonary abscesses and one dog with spontaneous pneumothorax due to the presence of pulmonary bullae. All dogs underwent median sternotomy under general anesthesia to explore the thorax. A pecto-intercostal fascial plane block was performed by injecting local anesthetic bupivacaine in the parasternal fascial plane between the deep pectoral and external intercostal muscles to provide antinociception by anesthetizing ventral cutaneous branches of intercostal nerves second through sixth. Analgesia from the block resulted in reduced requirement of inhalant anesthesia and minimal requirement for opioid to augment analgesia intraoperatively. Median sternotomy is required to perform thoracic surgery in dogs with various thoracic pathologies. Pecto-intercostal fascial plane block is a locoregional technique that can blunt nociception arising from the ventral thorax and can significantly improve perioperative patient care in dogs undergoing median sternotomy by providing effective intraoperative and potentially postoperative analgesia.

Midclavicle block: An anatomical study.

Recent studies indicate that clavipectoral fascia plane block (CPB) efficacy may stem from injectate distribution to the anterosuperior clavicular periosteum. We conducted an anatomical study combining the CPB with injection within the subclavius muscle. Our hypothesis was that the anaesthetic injectate would fully cover both the anterosuperior and posteroinferior surfaces of the clavicular periosteum in the midclavicular region. Observational human cadaver study. Laboratory of Surgical Neuroanatomy, Unit of Anatomy and Human Embryology of the Faculty of Medicine and Health Sciences, University of Barcelona. Five fresh human cadavers. The cadavers received both a CPB and subclavius muscle injections under ultrasound guidance in 10 clavicular regions. After the procedures on the cadaveric models, an anatomical dissection by planes was performed to evaluate the distribution pattern of methylene blue on the clavicular periosteum. A probabilistic map of the colour spectrum and staining temperature on the clavicular surfaces was generated. Methylene blue stained 37 ± 16% of the anterosuperior surface and 23 ± 13% of the posteroinferior surface of the clavicular periosteum, particularly in the middle third of each surface. Although the staining did not achieve complete circumferential coverage or perfect alignment between the surfaces, the areas exhibited a close relationship, indicating significant distribution and relevant coverage. Our anatomical study demonstrates that the midclavicular block achieves effective distribution around the middle third of the clavicle, although complete circumferential anaesthesia of the clavicular periosteum was not achieved. Although this block may provide periosteal and bone anaesthesia, it does not address other sources of pain, such as muscle spasms and skin components. Additional clinical studies are needed to evaluate the overall efficacy of this dual block technique for clavicle surgery.

Clavipectoral fascial plane block versus superficial cervical plexus block for fracture clavicle surgery: a randomized clinical trial

Background & objective: Both, the clavipectoral fascial plane block as well as superficial cervical plane block have been utilized as a regional anesthesia technique for clavicular fracture surgery. We compared the efficacy and safety of clavipectoral plane block with superficial cervical plexus block for intraoperative and postoperative pain relief in clavicular fracture surgery under general anesthesia (GA). Methodology: This double-blinded randomized controlled trial included 84 patients, aged between 21 and 60 y, ASA classification I and II, with fracture clavicle, either isolated or part of other trauma, undergoing fracture clavicle fixation. The patients were divided into two groups. The first group received a clavipectoral fascial plane block and the other received a superficial cervical plane block. The visual analogue scale (VAS) scores were recorded as primary outcome, while the patients’ hemodynamics, time to first rescue analgesic, and total morphine consumption were the secondary outcomes at post-anesthesia care unit (PACU) then every 2 h in the ward till 8 h. Results: Compared to the superficial cervical plexus block the clavipectoral plane block was superior in analgesia and more effective during surgical dissection and intraoperative manipulations with a clinically and statistically significant difference all the time from PACU to 8 h postoperatively. The heart rate and arterial blood pressure were much more stable in the clavipectoral group. Also, time to first rescue analgesic was more in the clavipectoral group than in the superficial cervical block. Total morphine consumption was significantly less in the clavipectoral group than in the superficial cervical group. Conclusion: Clavipectoral plane bock is superior to superficial cervical block in fracture clavicle surgeries regarding efficacy and safety. Postoperative pain, measured by VAS, was less with clavipectoral plane block, with more hemodynamic stability and less opioid consumption postoperatively.

Computed tomographic features of Morel-Lavallée lesions in 3 cats.

To describe the CT features of Morel-Lavallée lesions (MLLs) and their association with trauma in cats. This study aimed to investigate whether MLL fluid in cats accumulates between the dermis and deep fascia near superficial trauma, exhibits a vertical attenuation gradient, and shows no or only mild contrast enhancement on CT images. 3 young cats: a 1-year-old neutered male domestic shorthair cat, a 2-year-old neutered male domestic shorthair cat, and a 3-year-old neutered female British Shorthair cat. The clinical presentation of the 3 cats in the study involved recurrent swelling and fluid accumulation affecting at least 1 pelvic limb following trauma. In all cases, there was a fluid-filled space deep to the skin and superficial subcutaneous layer but superficial to the deep fascial plane overlying the muscular component of the pelvic limbs. The MLL fluid had a vertical attenuation gradient and no or only mild contrast enhancement. Morel-Lavallée lesions are often initially overlooked, likely due to distraction by concomitant significant bone injuries, and can be mistaken for hematomas, seromas, subcutaneous edema, contusions, or cellulitis, leading to less aggressive treatment. If left untreated, MLLs present a significant risk of extensive skin necrosis compared to other types of subcutaneous swelling.

Nerve Blocks for Post-Surgical Pain Management: A Narrative Review of Current Research.

Opioids remain the mainstay of post-surgical pain management; however, concerns regarding addiction and side effects necessitate the exploration of alternatives. This narrative review highlights the potential of nerve blocks as a safe and effective strategy for post-surgical pain control. This review explores the use of various nerve block techniques tailored to specific surgical procedures. These include nerve blocks for abdominal surgeries; fascial plane blocks for chest surgeries; nerve blocks for arm surgeries; and nerve blocks for lower limb surgery including; femoral, hip, and knee surgeries. By targeting specific nerves, these blocks can provide targeted pain relief without the negative side effects associated with opioids. Emerging evidence suggests that nerve blocks can be as effective as opioids in managing pain, while potentially offering additional benefits such as faster recovery, improved patient satisfaction, and reduced reliance on opioids. However, the effectiveness of nerve blocks varies depending on type of surgery, and in individual patients. Rebound pain, which temporary increase in pain after a block wears off, can occur. In addition, some techniques require specialized guidance for accurate placement. In conclusion, nerve blocks show great promise as effective alternatives for managing post-surgical pain. They can reduce the need for opioids and their side effects, leading to better patient outcomes and satisfaction. Future studies should assess the long-term impacts of specific nerve blocks on mortality rates, cost-effectiveness, and their incorporation into multimodal pain management approaches to further enhance post-surgical care.

To Study the Efficacy of Ultrasound Guided Pecto-Intercostal Fascial Plane Block in Patients Undergoing Midline Sternotomy in Open Cardiac Surgery: A Randomized Prospective Comparative Study.

The incidence of acute poststernotomy pain after cardiac surgery is 80%1. Pecto-intercostal fascial plane block (PIFB) adjacent to the sternum anesthetizes the anterior cutaneous branches of the intercostal nerves and may provide effective analgesia after sternotomy. A randomized controlled, double-blinded, prospective comparative trial was conducted at a tertiary care center on patients of midline sternotomy between 18 and 65 years and NYHA Class 2 and 3 for open cardiac surgery with the primary aim to evaluate analgesia on deep breathing after 3 hours of PIFB block bilaterally. A total of 60 patients were enrolled and randomly divided into three groups. PIFB was administered bilaterally before extubation, with 15 ml 0.125% bupivacaine plain (Group B), and bupivacaine+ clonidine 0.25 mcg/kg (Group B+C). Group C did not receive any intervention. All patients received acetaminophen 1 gram three times a day and injectable tramadol 1 mg/kg as a rescue analgesic. Baseline characteristics were similar among all the groups. The Numeric Rating Scale (NRS) for pain was statistically lower (P < 0.05) in Groups B and B+C compared to Group C at rest, deep breathing, and coughing at 3, 6, and 12 hours after extubation. NRS on deep breathing in Groups B, B+C, and C was {(2.3, 1.5, 4.4) at 3 hours, (2.3, 1.6, 4.3) at 6 hours, (2.8, 2.1, 3.9) at 12 hrs, and {(4.3, 3.5, 3.6)} at 24 hours after extubation. The peak expiratory flow rate was the highest in Group B. Rescue analgesia was not required in Group B. PIFB reduces sternotomy pain compared to the control group on deep breathing at 3 hours after block, with delayed requirement of rescue analgesia and improved respiratory mechanics in terms of peak expiratory flow rate at all time points. There is no benefit from adding clonidine.

Ultrasound-guided transversalis fascia plane block or transversus abdominis plane block for recovery after caesarean section: A randomised clinical trial.

Caesarean section is a widely performed surgical procedure that often results in moderate-to-severe postoperative pain. If left untreated, this pain can lead to short-term and long-term consequences. Transversalis fascia plane (TFP) block and transversus abdominis plane (TAP) block are among the regional anaesthesia techniques employed for managing pain after a caesarean section. We aimed to compare the impact of these two blocks on the quality of recovery in patients undergoing elective caesarean section under spinal anaesthesia. A single-centre, double-blind, randomised trial. Operating room, postanaesthesia recovery unit, and ward in a tertiary hospital. Ninety-three patients (ASA 2 to 3) were recruited. After exclusion, 79 patients were included in the final analysis: 40 in the TFP block group and 39 in the TAP block group. After surgery, participants received either TFP block (20 ml 0.25% bupivacaine for each side) or TAP block (20 ml 0.25% bupivacaine for each side). The primary outcome was the difference in obstetric quality of recovery 11-Turkish (ObsQoR-11T) scores between groups. Secondary outcomes included pain scores, opioid consumption and incidence of opioid-related complications. The mean ObsQoR-11T score was higher in the TFP block group compared with the TAP block group (97.13 ± 6.67 points vs. 87.10 ± 9.84 points, respectively; P < 0.001). The pain scores in the TFP block group were slightly lower between postoperative 4 and 24 h. The mean total morphine consumption was 15.08 ± 2.21 mg in the TFP block group and 22.21 ± 3.04 mg in the TAP block group ( P < 0.001). More patients required rescue analgesia between 4 and 8 h in the TAP block group [2.00 (5.00%) vs. 9.00 (23.08%), P = 0.02]. No significant differences were observed between groups in terms of opioid-related side effects. TFP block used for analgesic purposes yielded a better quality recovery period than TAP block and also reduced opioid consumption. Clinicaltrials.gov (NCT05999981). http://links.lww.com/EJA/B6 .

A 26 years old primigravida woman presented with abdominal cutaneous entrapment syndrome: a case report

BackgroundAbdominal cutaneous nerve entrapment syndrome (ACNES) is characterized by severe, mostly refractory, chronic pain due to the entrapment of the cutaneous branches of the lower torso intercostal nerves at the lateral edge of the rectus abdominis muscle. ACNES is rare compared to other pregnancy-related peripheral neuropathies and is often overlooked as a differential diagnosis for abdominal pain, despite the diagnosis relying primarily on patient history and physical examination. Emergency physicians and other medical personnel’s lack of exposure to such cases results in unnecessary laboratory requests, repeated visits, and increased fear and tension for the patient.Case presentationA 26-year-old primigravida on her second trimester of pregnancy presented to our Emergency department with persistent localized right upper quadrant abdominal pain. Despite repeated visit to the nearby hospital, no diagnosis was settled and the pain persisted. At our ED after a thorough history, physical examination and diagnostic test no abnormality was found. Finally Abdominal cutaneous nerve entrapment syndrome (ACNES) was considered and a mixture of 1 ml 2% lidocaine with adrenaline and 1 ml dexamethasone (4 mg) was infiltrated into the fascial plane in a fanning fashion into the most tender area using a modified technique and the patient reported significant improvement in pain.ConclusionAbdominal cutaneous nerve entrapment syndrome (ACNES) is a cause of abdominal pain in pregnancy that is often overlooked. The objective of this study is to describe a rare case of ACNES in a 26-year-old primigravida woman who presented to a low-resource emergency department to assist patient management.

Phenolic Compositions of Different Fractions from Coffee Silver Skin and Their Antioxidant Activities and Inhibition towards Carbohydrate-Digesting Enzymes.

Seeking food-derived antioxidants and inhibitors of α-glucosidase and α-amylase has been recognized as an effective way for managing diabetes. Coffee silver skin (CSS) is rich in phenolic compounds, which may be potential agents as antioxidants and for α-glucosidase and α-amylase inhibition. But whether phenolics in different forms show similar bioactivity remains unknown. In this study, phenolic compounds in CSS were extracted as free phenolics (FPs), esterified phenolics (EPs), and bound phenolics (BPs). The phenolic profiles and antioxidant activities of them were investigated. Their inhibitory effects on α-glucosidase and α-amylase were analyzed, and the inhibitory mechanisms were elucidated by molecular docking and molecular dynamic simulation. Results showed that FPs exhibited the best antioxidant ability and inhibitory effects on α-glucosidase and α-amylase. A total of 17 compounds were identified in FPs with 3-caffeoylquinic acid, 4-feruloylquinic acid, and dicaffeoylquinic acids as the dominant ones. Typical phenolics in FPs could bind to α-glucosidase and α-amylase through hydrogen bonds and form hydrophobic interaction with several key amino acid residues. In addition, 3,4-dicaffeoylquinic acid and 3-caffeoylquinic acid might be the principal components that account for the inhibitory effect of FPs on α-glucosidase. The results of this study may provide some scientific support for CSS utilization as a health-beneficial component in functional food development for type 2 diabetes mellitus management.

Is the combination of interfascial plane blocks sufficient for awake breast cancer surgery? An observational, prospective, proof-of-concept study

IntroductionBreast cancer is the most prevalent cancer among women, often necessitating surgical intervention. While surgeries like lumpectomy can be performed under local anesthesia, more extensive procedures typically require general anesthesia. Awake breast cancer surgery has emerged as an alternative due to risks associated with general anesthesia and patient preference.MethodsThis prospective observational study, conducted from July 2022 to July 2023, evaluated the effectiveness of ultrasound-guided fascial plane blocks for awake breast surgery. Patients aged 18–80 years undergoing unilateral breast surgery were included, following ethical committee approval and written informed consent. Exclusion criteria were prior breast surgery, coagulopathies, infections, allergies to local anesthetics, psychiatric disorders, body mass index over 40 kg/m², and chest deformities. The combination of interpectoral, pecto-serratus, and deep serratus plane blocks was used as the primary anesthetic method, with a superficial parasternal block added in cases where complete cutaneous coverage was not achieved.ResultsSeventeen patients were enrolled. The primary outcome, sufficient surgical anesthesia without deep sedation, was achieved in 15 patients. The combination of the aforementioned blocks proved effective, with an average surgery duration of 59.66 min, and propofol requirements averaging 1.77 mg/kg/hour. Most patients reported high satisfaction levels, and no early or late block-related complications were observed.ConclusionThe combination of fascial plane blocks is a viable option for awake breast cancer surgery, potentially eliminating the need for more invasive anesthesia techniques. Further studies are necessary to confirm these findings in larger, homogeneous patient groups.

Cookies Fortified with Polyphenols Extracts: Impact on Phenolic Content, Antioxidant Activity, Inhibition of α-Amylase and α-Glucosidase Enzyme, Colour and Sensory Attractiveness.

The goal of the research was to determine the impact of fortification with polyphenolic compounds on (i) sensory attractiveness (global satisfaction, appearance, colour, odour, flavour, sweetness, bitterness), (ii) content of polyphenols and colour (L*, a*, b*) after the baking process and (iii) their bioactive potential (antioxidants activity and inhibiting of α-amylase and α-glucosidase enzyme). Fortification was made with extracts of polyphenolic compounds of selected plant raw materials rich in polyphenols from quince (fruits), tilia (flowers), pomegranate (skin), passion fruit (endocarp), sour cherries (leaves), haskap and chokeberry (berries), silver skin (coffee beans), rosehip (seeds). Depending on the nature of the polyphenol extract, flavan-3-ols (monomeric and polymeric), phenolic acid, flavonols and anthocyanins were identified in the product in amounts ranging from 53.7 to 212.6 mg/100 g DM. Cookies' colour (L*, a*, b*) depended on the type of polyphenol extract used for fortification. Cookies with haskap, chokeberry and sour cherry presented the highest antioxidant potential. Cookies with chokeberry, haskap and rosehip presented high activity in inhibiting α-amylase (65.5, 60.6 and 62.2% of inhibition, respectively), but cookies with haskap, silver skin and quince in inhibiting α-glucosidase activity (23.0, 20.4 and 21.4% of inhibition, respectively). In the sensory evaluation, the most attractive were cookies with rosehip and pomegranate (6.3 and 5.8 score, respectively), but the lowest ratings were given to cookies with passion fruit and silver skin but especially quince cookies, which obtained the lowest desirability (3.7 score). The acceptability of fortified cookies was determined to the least extent by monomeric flavan-3-ols and phenolic acids (in minus in odour/flavour, bitterness, sweetness and global satisfaction), but anthocyanins, polymeric procyanidins and flavonols had the most significant positive impact on consumer acceptance of the assessed features, i.e., global satisfaction, odour/flavour, sweetness and bitterness (positive consumer drivers).

Retroperitoneal Approach to D3-Lymph Node Dissection With Left Colic Artery Preservation in the Treatment of Sigmoid Cancer.

Laparoscopic approaches and robot-assisted operations are used for colorectal cancer surgery because of their minimal invasiveness.1 However, changes in intra-abdominal pressure during laparoscopy can lead to cardiovascular complications in compromised patients;2 obesity and intraabdominal adhesions may further interfere with laparoscopic procedures. The retroperitoneal approach may facilitate minimally invasive surgery, even in patients with comorbidities. The technique for high ligation of the inferior mesenteric artery has been described in left colonic surgeries.3 However, complete termination of the blood supply through this artery may lead to a higher frequency of anastomotic leakage.4. We present a novel retroperitoneal approach for D3-lymph node dissection with low ligation of the inferior mesenteric artery and preservation of the left colic artery. This method can reduce the duration of laparoscopic procedures for compromised patients and meet the standards for extended lymph node dissection with tumor-specific mesocolic excision.5,6. The procedure started with the installation of a paraumbilical optical trocar to introduce a 30-degree optical system. The SILS™ Port (Covidien, Medtronic) was inserted into the retroperitoneal space via a 4-cm incision, made 2 cm below and parallel to the anterior superior iliac spine in the left flank under the control of the optical system. The horizontal aspect of the duodenum served as the cranial landmark during interfascial dissection, with the dissection proceeding in a cranial and medial direction. During the dissection, the left ureter was the primary landmark, passing medial to the gonadal vessels and Gerota's fascia.The aorta was exposed medially and the inferior mesenteric artery was identified. The inferior mesenteric artery was skeletonized from its origin until the branching of the left colic artery and the sigmoid artery. The left colic artery was skeletonized until the passage of the inferior mesenteric vein, and the apical lymphatic nodes with mesocolic tissue were mobilized and excised. The inferior mesenteric artery was cut below the left colic artery.The final step was performed laparoscopically. The parietal fascia along Toldt's line was cut laterally to complete the mesocolon excision. The parietal fascia was cut along the right side of the aorta to free the mesocolonic medial border. The sigmoid mesocolon was dissected at the proximal and distal resection margins.Following mobilization, the colon was cut 10 cm distal to the tumor margin using a linear stapler. The specimen was then extracted using an SILS incision. The sigmorectal anastomosis was made. Atypical hepatic resection was performed using two additional trocars. The incidence of pain syndrome in the early postoperative period was low. Blood loss reached 100 mL. The duration of the surgery was 300 min. The retroperitoneal step took 63 min. Metastases were observed in 7 of the 41 harvested lymph nodes. The patient was discharged on the 8th postoperative day. The retroperitoneal technique can be safely performed. Anatomical structures are readily accessible and easily visualized with this approach after special training, enabling extended lymph node dissection.

Development and properties of bio-based polymer composites using PLA and untreated agro-industrial residues

This research developed a bio-based polymer composite using polylactic acid (PLA) and agro-industrial residues from coffee by-products (without chemical modification and the use of coupling agents or stabilizers). Agro-industrial residues, such as spent coffee ground (SCG) and coffee silver skin (CSS) as filler, were added into the PLA matrix in different percentages by weight, from 0.5 to 10 wt%. The bio-composites were prepared using solvent-cast films and were characterized by various techniques, including FT-IR, TGA, DSC, XRD, SEM and mechanical tests. Bio-composites' formation was verified using FT-IR and SEM; the material showed good interfacial interaction, with percentages between 3 and 5 wt%. XRD and DSC determined the percentage crystallinity in the bio-composites. SEM found that the bio-composites form crystals, showing their limits after mechanical testing. The bio-composites exhibited enhanced thermal and mechanical properties compared to neat PLA.These bio-based composites show great potential for a wide range of applications in the food industry, including disposable and single-use materials, as well as food packaging. Moreover, their use can significantly contribute to the global demand for eco-friendly materials.

Point-of-Care Ultrasound Diagnosis of Early Pyomyositis in a Pediatric Patient: A Case Report.

Skin and soft tissue infections are common in the pediatric emergency department. Because pyomyositis occurs deep to the fascial plane, it is often difficult to appreciate on physical examination. The utility of point-of-care ultrasound for identifying pyomyositis is of great value to the pediatric emergency physician as this diagnosis has a different expected clinical course and requires different management than other skin and soft tissue infections. This case report describes a child who presented to the pediatric emergency department with leg pain and redness, initially concerning for an abscess based on clinical findings. Point-of-care ultrasound diagnosed early pyomyositis, prompting early involvement of the pediatric surgical service and urgent computed tomography imaging, which confirmed the diagnosis.

EP568 - A rare case of necrotizing fasciitis caused by Streptococcus Anginosus and Staphylococcus Lugdunensis

Abstract Necrotizing fasciitis (NF) is a rare soft tissue infection involving the fascial planes, causing rapid and extensive tissue destruction. We present a unique case of NF in a patient with poor glycemic control caused by atypical pathogens. A 66-year-old female with a recent biopsy for a wart-like lesion developed a wound infection, with greenish-black exudate. Initial observations were: temperature: 39.4 degrees, heart rate: 105, GCS: 15/15. Physical examination revealed a grossly filiform lesion below her abdominal apron measuring 7cm in diameter. The patient was empirically treated with IV Co-Amoxiclav. Abnormal biochemistry results are shown below. Microbiological analysis revealed Streptococcus Anginosus, anaerobes and Staphylococcus Lugdunensis. CT abdomen revealed extensive inflammatory changes with gas and fluid collection and enlarged pelvic and inguinal lymph nodes. Two urgent surgical explorations and debridements, with meticulous wound care using negative pressure wound dressings (Prevena) were done. Intravenous Gentamicin, Benzylpenicillin, Clindamycin, Metronidazole and Flucloxacillin were administered for six weeks. The patient's clinical status gradually improved. Streptococcus Anginosus, that is part of the Streptococcus Milleri group and Staphylococcus Lugdunensis, a coagulase-negative Staphylococci (CoNS) are commensal organisms of the oral and gastrointestinal tracts. These organisms possess virulence factors that facilitate tissue invasion and destruction, causing an aggressive course of NF. This case highlights the importance of considering atypical pathogens, especially in patients with predisposing factors such as diabetes and obesity. Early recognition, prompt surgical intervention and a multidisciplinary approach are essential for improving outcomes in these cases.TestResultWhite Blood Cells (WBC)22,200 [WBCs per microliter]Sodium123 [mmol/L]Chloride88 [mmol/L]C-reactive protein (CRP)318 [mg/L]Blood Glucose19.3 [mmol/L]

Simulation tools in ultrasound-guided regional anesthesia: developing a simple, inexpensive erector spinae plane (ESP) block teaching model.

The erector spinae plane (ESP) block is an increasingly utilized regional block in the emergency department, representing one effective alternative or adjunct to opioid analgesia in patients presenting with rib fractures. While there is growing interest, its widespread adoption faces hurdles, such as a lack of appropriate training resources. Gelatin-based phantoms to simulate human anatomy have been widely used to facilitate ultrasound-guided procedures, although no such model for the ESP block has yet been defined in the literature. To address this gap, we sought to design and assemble an inexpensive, simple to build, reusable phantom to simulate the sonographic anatomy of the posterior thoracic wall and serve as a task trainer for an ultrasound-guided ESP block. This novel phantom model reproduces an ultrasonographic fascial plane using a gelatin medium and 3D-printed thoracic spine with ribs allowing for needle guidance and hydrodissection.

The biliary atresia susceptibility gene, EFEMP1, regulates extrahepatic bile duct elastic fiber formation and mechanics

IntroductionEGF-Containing Fibulin Extracellular Matrix Protein 1 (EFEMP1, also called fibulin-3) is an extracellular matrix protein linked in a genome-wide association study to biliary atresia, a fibrotic disease of the neonatal extrahepatic bile duct. Fibulin-3 is deposited in most tissues and Efemp1 null mice have decreased elastic fibers in visceral fascia; however, fibulin-3 does not have a role in the development of large elastic fibers and its overall function in the extrahepatic bile ducts remains unclear. MethodsWe used staining and histology to define the amount and organization of key extracellular matrix components in the extrahepatic bile ducts. We also repurposed pressure myography, a technique heretofore applied to the vasculature, to determine the contribution of elastin and fibulin-3 to extrahepatic bile duct mechanics. We examined extrahepatic bile duct structure and mechanics in three models: neonatal vs. adult rat ducts (n=6 each), elastase-treated adult rat ducts (n=6-7 each), and Efemp1+/- vs. wild type mouse ducts (n=6 each). ResultsWe demonstrated that fibulin-3 is expressed in the submucosa of both neonatal and adult mouse, rat and human extrahepatic bile ducts and that, in adult Efemp1+/- mouse ducts, elastin organization into fibers is decreased by approximately half. Pressure myography showed that Efemp1+/- ducts have altered mechanics compared to control ducts, with Efemp1+/- ducts displaying significant stretch compared to controls (p=0.0376); these changes in stretch are similar to those observed in elastase-treated compared to normal ducts (p<0.0001) and in neonatal ducts compared to adult ducts (p< 0.0001). ConclusionFibulin-3 has an important role in the formation of elastic fibers and the mechanical properties of the extrahepatic bile duct. This provides functional relevance for the biliary atresia susceptibility gene EFEMP1. Impact and ImplicationsThe gene EFEMP1 was found via a genome wide association study to be a susceptibility gene for the neonatal disease biliary atresia. EFEMP1 encodes the protein fibulin-3, which regulates elastic fiber organization in the extrahepatic bile duct (EHBD), the major site of disease in biliary atresia. We showed that neonatal EHBDs as well as mice heterozygous for Efemp1 have decreased numbers of elastic fibers, and that this alters EHBD mechanics. This work is important for understanding the mechanism of biliary atresia, in particular susceptibility to obstruction.

Comparison of erector spinae plane and transversus abdominis plane block for postoperative analgesia after caesarean delivery under spinal anaesthesia: A randomised controlled trial

BackgroundTruncal blocks contribute to multimodal analgesia that enhances early recovery after caesarean delivery. The transversus abdominis plane (TAP) block is an established technique that offers somatic abdominal wall analgesia. The erector spinae plane (ESP) block is a fascial plane technique that may offer additional visceral analgesic effects. This study hypothesized that ESP block would offer superior analgesic efficacy to TAP block in women undergoing caesarean delivery under spinal anaesthesia. MethodsSixty-six ASA physical status grade 1–3 (≥18 years) patients undergoing elective caesarean delivery under spinal anaesthesia were randomly allocated to receive either bilateral ultrasound-guided TAP (N = 33) or ESP blocks at the T9 vertebral level (N = 35). The primary outcome measure was 24-hour cumulative morphine consumption. The secondary outcomes included time to first analgesic request, duration of block placement, numeric rating scale (NRS) pain scores at rest and movement, effect of pain on activities of daily living (ADLs) and care for the infant, patient analgesic satisfaction, frequency and severity of opioid-related side effects. ResultsThere was no statistically significant difference in mean (95% CI) 24-hour cumulative morphine consumption between groups: 32.0 (27.0 to 37.0) mg with TAP versus 27.0 (19.9 to 34.0) mg with ESP (p = 0.16). The mean (SD) duration of block placement was longer for ESP than for TAP blocks (10.7 (2.2) minutes versus 9.0 (2.5) minutes; p = 0.004). There were no significant differences in the other secondary outcomes. ConclusionThis study found similar postoperative opioid use and analgesic efficacy between ESP and TAP block after caesarean delivery performed under spinal anaesthesia.Trial Registration: South African National Clinical Trial Registry (DOH-27-102022-5278): https://sanctr.samrc.ac.za/TrialDisplay.aspx?TrialID=8100, Pan African Clinical Trials Registry (PACTR202301645957324): https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=24267.

Suppurative Cervicomediastinitis From the Perspective of the Head and Neck Surgeon in a Tertiary Treatment Unit.

Introduction Cervical suppurations represent an emergency pathology, with a dramatic evolution in the absence of adequate treatment. It frequently affects young people, hence the medico-legal implications of these cases. The anatomical substrate for the development of these deep cervical suppurations is represented by the cervical fascia and spaces. A distinct and extremely serious sub-chapter within diffuse cervical suppurations is necrotic cervical fasciitis, a polymicrobial infection with the most common oropharyngeal or odontogenic starting point, with rapidly progressive, destructive evolution in the deep fascial planes of the neck. Materials and method We will present a retrospective clinical study carried out on 26 cases diagnosed and treated between September 2013 and September 2018 in the ENT Clinic Department of the Bucharest University Emergency Hospital. Results Our retrospective analysis of a cohort of 26 patients in a tertiary referral center showed that deep cervical suppurations are slightly more common in men than in women. The most affected age groups were 50-59 years, followed by 20-29 years, representing a percentage of 53.84% of all cases. Also, 53.84% of the studied patients with deep cervical suppurations had a precarious and modest status. The most common clinical signs at presentation were malaise, cervical swelling, neck pain, dysphagia, fever, dysphonia, dyspnea, and cervical erythema. More than 60% of suppurations were odontogenic and 23% were caused by a traumatic element. Diabetes mellitus represents a comorbidity in 30.8% of patients, while 42.3% of patients had no personal pathological history, and thus this pathology has a lethal potential also in a patient in full health. In the study group, 46 (15%) had cervicomediastinitis, and 61.53% developed necrotizing fasciitis. One-third (34.61%) of our patients had undergone previous drainage surgery. Bacteriological examinations of the wound were with group C, D, G betahemolytic streptococcus, while 61.53% of the cultures were negative. Most patients required at least two cervicotomies. The average duration of hospitalization was 28.26 days, and the mortality rate was 23.07%; therefore, practically, one out of four cases resulted in death. In the studied group, no direct relationship can be established between the length of hospitalization and the favorable and unfavorable evolution of the patient. We propose a 10-step management protocol for the management of a cervical suppuration. Conclusion The multidisciplinary approach to these suppurations by the head and neck surgeon, the thoracic surgeon, the oromaxillofacial surgeon, anesthetist, imagist, specialist in infectious diseases, pathologist, psychologist, and so on, is the key to success in a patient who presents not only a suppuration in the throat but also a disease with systemic resonance and significant lethal potential.
