Lumbar erector spinae plane block versus infrainguinal fascia iliaca compartment block for pain management after total hip arthroplasty: a randomized clinical trial.

OBJECTIVE: We aimed to evaluate the effectiveness of ultrasound-guided facia iliaca compartment (FIC) and erector spinae plane (ESP) blocks in managing postoperative pain after total hip arthroplasty surgery. METHODS: A total of 60 patients were randomized into 2 groups (n = 30): one that received FIC blocks and one that received ESP blocks. FIC and ESP blocks were performed with 30 mL 0.25% bupivacaine at the end of the surgery. The patients received intravenous tramadol and patient-controlled postoperative analgesia. The pain scores, opioid consumption, and adverse events were recorded. RESULTS: The dynamic pain scores on movement in the postoperative first hour were significantly lower in the ESP block group than in the FIC block group (3 [2-4] vs 4 [2-5], respectively; P = .035). Data are expressed as median (25th-75th percentiles). Postoperative opioid consumption within the first postoperative 8 hours was significantly higher in the FIC block group than in the ESP block group (80 mg [61-100] vs 100 mg [80-120], respectively; P = .010). The adverse effects of opioids did not differ between the 2 groups. CONCLUSION: ESP and infrainguinal FIC blocks provided similar postoperative analgesia 24 hours after total hip arthroplasty. The ESP block is more beneficial than the FIC block in terms of pain scores and opioid consumption in the early hours of the postoperative period.

Surgical vs ultrasound-guided lumbar erector spinae plane block for pain management following lumbar spinal fusion surgery.

PURPOSE: Spinal surgery is associated with severe diffuse pain in the postoperative period. Effective pain management plays an essential role in reducing morbidity and mortality. This study is designed to compare the ultrasound-guided erector spinae plane (ESP) block and surgical infiltrative ESP block for postoperative analgesia management after lumbar spinal fusion surgery. METHODS: The patients who underwent two or three levels of posterior lumbar spinal fusion surgery were randomly allocated into one of three groups with 30 patients each (Group SE = Surgical ESP block; Group UE = ultrasound-guided ESP block; Group C = Controls). The primary aim was to compare postoperative opioid consumption, and the secondary aim was to evaluate postoperative dynamic and static pain scores and the incidence of opioid-related adverse effects. RESULTS: There was a significant difference in terms of opioid consumption, rescue analgesia on demand, and both static and dynamic pain scores between groups at all time periods (p < 0.05). Group SE and Group UE had lower pain scores and consumed fewer opioids than the controls (p < 0.05). However, the Group UE had lower pain scores and opioid consumption than the Group SE. The sedation level of patients was significantly higher in the control group than in the other two groups. Also, nausea was more common in controls than in the other groups. CONCLUSION: While both surgical and ultrasound-guided ESP blocks reduced opioid consumption compared to the controls, the patients who received ultrasound-guided ESP blocks experienced better postsurgical pain relief than those in the other groups (surgical ESP and controls).

Preparation of NDI-BODIPY Based Photo Catalyzers for Green LED Irradiated Synthesis of Juglone.

Photochemistry related studies have been driven by with the application of new types of photocatalysis. Lately boron-dipyrromethene (BODIPY) as distinguished chromophore with exceptional photophysical and chemical features has emerged as a viable photosensitizer. Within this context, three new NDI-BODIPY triads (8-10) were synthesized/ characterized and used to investigate the efficiencies of singlet oxygen generation and oxidation of 1,5-dihydroxynapthalene to juglone under visible light. Singlet oxygen generation was determined both via indirect method by using 1,3-diphenylisobenzofuran as trap molecule and from the characteristic 1O2 phosphorescence at 1270 nm. Also, NDI with BODIPY dyes bearing bromine and iodine atoms were shown to be highly active photocatalysts in which the activities are comparable or higher to the readily available commercial systems where 36% (9) and 66% (10) juglone production was achieved under 15 min. This work may emphasize good example of applying NDI-BODIPY based triads as photocatalysts for a series of important organic transformations.

Transvaginal pudendal nerve blocks in patients with pudendal neuralgia: 2-year follow-up results.

PURPOSE: Pudendal neuralgia (PN) is an extremely painful neuropathy of the pudendal nerve resulting in a negative impact on a patient's quality of life. The aim of this study is to evaluate the 2-year outcomes of repetitive doses of the transvaginal pudendal nerve injections (PNI), and to compare the success of the PNI concerning anatomical levels (endopelvic and extrapelvic portion) of the pudendal nerve pathology. METHODS: This retrospective longitudinal cohort study consists of patients with PN diagnosed with the first four essential Nantes criteria. Diagnostic PNI was performed on 67 patients to fulfill the fifth criteria of Nantes. A total of 56 patients who responded to the initial diagnostic PNI underwent therapeutic repeated transvaginal PNIs twice for 3 weeks apart. Mean pain intensity scores were measured using a visual analog scale at the 1st, 3rd, 6th, 12th, and 24th months after the therapeutic blocks were completed. Effectiveness of the PNIs' was defined as ≥ 50% improvement of the initial pain, and relative improvement was defined as 30-50% improvement of the initial pain. Treatment failure was defined as the reduction of the initial pain by less than 30% or the return of the pain to its worst condition. RESULTS: The efficacy of the PNIs significantly declined over time. Pudendal nerve blocks provided a significant decrease in pain scores; however, this decrease lost its strength significantly in the 24th month. The intervention was more effective in entrapments of the pudendal nerve between sacrospinous and sacrotuberous ligaments or below (Level-2) when compared to the injuries in the endopelvic part (Level-1). More than 50% pain reduction continued in five patients with pathology at Level-1 and 24 patients with pathology at Level-2. CONCLUSION: Repeated PNIs could provide a significant decrease in pain scores for both short- and long-term periods. However, the efficacy of the PNIs declined over 2 years. The success of PNIs may be affected by the anatomical level of the nerve injury; therefore, interligamentous pudendal nerve entrapment cases have more benefits than the cases of pudendal nerve entrapment in the endopelvic part. However, it is recommended to perform therapeutic nerve blocks even in patients with suspected endopelvic pudendal nerve pathology before the referral to surgery.

Our anesthesia experiences in COVID-19 positive patients delivering by cesarean section: A retrospective single-center cohort study.

AIM: Pregnancy increases susceptibility to respiratory complications of viral diseases. This study aims to evaluate our anesthesia practices in pregnant women with COVID-19 undergoing cesarean section. METHODS: A total of 61 patients who underwent cesarean section and had positive Polymerase chain reaction (PCR) testing for COVID-19 with nasopharyngeal swabs were included in the study. Patient demographics and information about anesthesia were analyzed retrospectively from the patient medical files. RESULTS: A total of 61 parturients undergoing cesarean section that had positive SARS-CoV-2 PCR tests were assessed. General anesthesia was applied to only three patients (4.9%), while spinal anesthesia was administered to the remaining 58 patients (95.1%). The incidence of hypotension was 25.9% in the spinal anesthesia group. Forty-one (67.2%) parturients were asymptomatic. While the rate of pneumonia in symptomatic patients was 45% (9/20), the pneumonia incidence among all SARS-CoV-2 PCR (+) parturients was 14% (9/61). Three (4.9%) COVID-19 patients required intensive care in the perioperative period. The overall mortality rate was 1.6% (1/61) among parturients with COVID-19 undergoing cesarean section, while it was 11.1% (1/9) in patients with pneumonia. CONCLUSION: It was observed that COVID-19 is associated with mortality in pregnant women undergoing cesarean section. Spinal anesthesia was safely and effectively administered in COVID-19 parturients, especially in patients with pneumonia.

Comparison of the Effects of Sevoflurane and Desflurane on Endothelial Glycocalyx in Patients Undergoing Laparoscopic Hysterectomy: A Randomized, Double-Blind Trial.

Objective: Various enzymes, reactive oxygen species, inflammatory conditions, and major surgeries cause endothelial glycocalyx breakdown. Inhalation of anaesthetic agents may have protective effects on the endothelium. This study compared syndecan-1 and heparan sulfate levels to evaluate the effects of sevoflurane and desflurane on the endothelial glycocalyx. Methods: This prospective randomized, double-blind study included 46 patients undergoing laparoscopic hysterectomy. The participants were allocated into sevoflurane and desflurane groups. Subsequently, blood samples were drawn at three time points: before anaesthesia induction for a baseline value (T0), after pneumoperitoneum (T1), and after extubation (T2). Heparan sulfate and syndecan-1 levels were measured. Results: There was no statistical difference between the sevoflurane and desflurane groups in terms of heparan sulfate and syndecan-1 levels at any time point. A significant difference was found only in the desflurane group in the intragroup comparisons of the measurements of heparan sulfate levels (χ2=29.826, P < 0.001). Matched pairs of the time points in the desflurane group showed that P=0.036 (Z=-2.099) for T1-T0, P < 0.001 (Z=-3.924) for T2-T0, and P < 0.001 (Z=-4.197) for T2-T1. The change in percentage between T2 and T1 of heparan sulfate in the desflurane group was found to be statistically significant (P=0.034). Conclusion: The damage caused by surgical stress on the endothelial glycocalyx can be reduced by both desflurane and sevoflurane. The protective effect of desflurane is more prominent than that of sevoflurane.

Anxiety and Depression Symptoms of Family Members of Intensive Care Unit Patients: A Prospective Observational Study and the Lived Experiences of the Family Members.

Background The aim of this study is to investigate the factors affecting symptoms of anxiety and depression in the family members of critically ill patients. Methods This prospective cohort study was conducted in an adult tertiary care mixed medical-surgical intensive care unit (ICU) at a tertiary-level teaching hospital. The symptoms of anxiety and depression of first-degree adult relatives were evaluated with the Hospital Anxiety and Depression Scale. Four family members were interviewed and asked about their experiences during the ICU process. Results A total of 84 patients and their family members were included in the study. The symptoms of anxiety were present in 44/84 (52.4%), and depression was present in 57/84 (67.9%) family members. A nasogastric tube was found to be related to anxiety ( p = 0.005) and depressive symptoms ( p = 0.002). The family members of the patients with an acute developed illness had 3.9 (95% confidence interval [CI]: 1.4-10.9) times the odds of having the symptoms of anxiety and 6.2 (95% CI: 1.7-21.7) times the odds of having the symptoms of depression than the family members of the patients with an illness developed on a chronic basis. The family members of the patients who died in the ICU had 5.0 (95% CI: 1.0-24.5) times the odds of being depressed than the patients discharged from the ICU. All interviewees stated having difficulty understanding and remembering what was told. The common feelings of all the interviewees were desperation and fear. Conclusions Awareness of the emotional stress of family members can help develop interventions and attitudes to alleviate symptom burden.

Efficacy of epidural steroid injections and evaluation of surgical and anesthetic approaches in far-lateral disc herniations.

Aim: To observe the long-term effect of epidural steroid injections (ESI) and describe surgical outcomes in patients with far-lateral lumbar disc herniations. Materials & methods: The medical records of 30 patients who underwent surgery for far-lateral lumbar disc herniations were reviewed. Results: ESI outcomes: pain scores decreased significantly after ESI (p = 0.004). The surgery was delayed for 13.78 ± 8.59 months in patients who received ESI. Surgical outcomes: the improvement in the leg pain was considerably more significant than the back pain (p < 0.001). While motor deficit improved substantially (p < 0.001), there was persistent sensory dysesthesia. Conclusion: ESI does not prevent but may delay the surgery up to 28 months. Although postoperative pain scores were significantly decreased, there was persistent back pain and sensory paresthesia.

Far-lateral lumbar disc herniation is a rare condition, and it constitutes a specific group of lumbar disc hernias regarding its anatomic location. It causes far more severe and intractable back and leg pain than the other widely known group of disc hernias. Sometimes, it can lead to sensation disorders and even functional impairment in the legs. Few can benefit from conservative treatments, including painkillers and physical therapy so surgical treatment becomes inevitable in many patients. Lumbar steroid injections to the epidural space may provide significant symptom relief and delay surgery in certain patients.

The Effect of Ligamentotaxis on Clinical and Radiological Outcomes in Thoracolumbar Burst Fractures with High McCormack Grade.

The aim of this study was to investigate the effect of ligamentotaxis performed in combination with the posterior surgical approach in thoracic and lumbar burst fractures due to high-energy trauma with high McCormack scores (≥7). This observational study was conducted at the University of Health Sciences from January 2015 to December 2020. Medical records of 16 patients were retrospectively evaluated. The vertebral height measurements, local kyphosis angles, and anteroposterior spinal canal diameter were measured pre- and postoperatively. American Spinal Injury Association (ASIA), McCormack, and thoracolumbar injury classification and severity (TLICS) scores were also evaluated. All postoperative measurements showed a significant change. There was no statistical significance in the pre- and postoperative ASIA grades. No screw breakages were observed within a mean follow-up period of 35.50±11.79 months. Ligamentotaxis effectively increased the spinal canal diameter and provided vertebral height restoration and kyphosis angle correction in thoracolumbar burst fractures with a high McCormack score. However, no significant neurological improvement was observed in cases with neurological deficits, although laminectomy was performed with ligamentotaxis. Key Words: Ligamentotaxis, Lumbar vertebrae, Spine, Thoracic vertebrae, Thoracolumbar burst fractures, Trauma.

The impact of the first wave of the COVID-19 pandemic on hospital admissions and treatment management of ectopic pregnancy.

OBJECTIVES: We aimed to evaluate the clinical features and treatment strategies applied to the patients with ectopic pregnancy admitted to our tertiary care center before and during the pandemic. METHODS: Women aged 18-45 years, who were admitted to the hospital with a diagnosis of ectopic pregnancy in the pre- and postpandemic periods, were included in this case-control study. RESULTS: A total of 173 patients, 116 patients before the pandemic and 57 patients during the pandemic, were included in the study. The rate of admissions from the emergency department was higher during the pandemic than before the pandemic (P = 0.003). The rupture was detected significantly higher during the outbreak (13/116 [11.2%]) than before the pandemic (16/57 [28.1%]) (P = 0.009). While conservative treatment was applied more frequently in the prepandemic period, it was observed that patients were treated surgically more frequently during the pandemic period (P = 0.003). While laparoscopic surgery was preferred before the pandemic, laparotomy was applied to all patients during the pandemic (P < 0.001). CONCLUSIONS: In the first wave of the outbreak, there were delays in the diagnosis of ectopic pregnancies, and these patients presented with ruptures more frequently than before the pandemic. Furthermore, surgical treatment methods were used more than conservative therapies during the outbreak.

Severe Metabolic Acidosis, Acute Renal Failure, and Delayed Paralysis Leading to Respiratory Depression due to Manganese ethylene-bis-dithiocarbamate.

Maneb is a widely used agricultural fungicide, which can lead to parkinsonism due to its neurotoxic effects on the dopaminergic system after chronic low-dose exposure. Previous acute human maneb poisoning cases occurred with low-dose maneb exposure through the dermal route causing renal failure. This report presents a case of acute renal failure and delayed paralysis due to ingestion of a large dose of maneb for a suicide attempt. A 16-year-old female patient was admitted to the emergency room because of drinking almost a whole bottle of maneb (400 mL [2 g L-1]) about 2 hours before. The patient was transferred to the intensive care unit with severe metabolic acidosis and renal failure. On the 4th day in intensive care unit, although the severe acidosis was resolved with haemodialysis, the patient was intubated because of ascending muscle weakness and dyspnoea. After staying in the intensive care unit for 9 days and in the nephrology ward for 2 weeks, the patient was discharged well from the hospital with no further need for haemodialysis but a persistent bilateral drop foot. One year after the event, renal functions were normal, and motor function in the lower extremities improved entirely.

Factors influencing neonatal outcomes in twin pregnancies undergoing cesarean section: a cross-sectional study.

OBJECTIVE: This study aimed to evaluate maternal and fetal characteristics and factors affecting fetal outcomes in twin pregnancies delivered by cesarean section. METHODS: This was a cross-sectional study in a tertiary care referral hospital. The primary outcome was to ascertain the effects of independent factors on the 1st and 5th minute APGAR scores, neonatal intensive care unit admissions, the need for mechanical ventilation, and neonatal mortality. RESULTS: A total of 453 pregnant women and 906 newborns were included in the analysis. The final logistic regression model revealed that early gestational weeks and neonates <3rd weight percentile at the time of delivery were the most significant predictors of all poor outcome parameters in at least one of the twins (p<0.05). General anesthesia for cesarean section was associated with 1st minute APGAR<7 and the need for mechanical ventilation, and emergency surgery was correlated with the need for mechanical ventilation (p<0.05) in at least one of the twins. CONCLUSION: General anesthesia, emergency surgery, early gestational weeks, and birth weight <3rd weight percentile were strongly associated with poor neonatal outcomes in at least one of the twins delivered by cesarean section.

Estimating the Outcomes of Intracerebral Haemorrhage with Intracerebral Haemorrhage Score and Acute Physiology and Chronic Health Evaluation-II Score: A Multicentre Study.

OBJECTIVE: Spontaneous intracerebral haemorrhage causes mortality or leads to permanent disability in most of the survivors. Thus, determining the severity of the disease to predict mortality and morbidity is important. This study aimed to evaluate Acute Physiology and Chronic Health Evaluation-II and Intracerebral Haemorrhage scores in spontaneous intracerebral haemorrhage patients treated in intensive care units. METHODS: This multicenter study was conducted in 2 tertiary care hospitals' general intensive care units. Short- (in-hospital) and long-term (1-year) mortality and functional outcomes at discharge were evaluated using the Intracerebral Haemorrhage and Acute Physiology and Chronic Health Evaluation-II scores. RESULTS: Of the 35 spontaneous intracerebral haemorrhage patients analysed, the modified Ranking Scale was <4 in 10 (28.6%) patients and ≥4 in 25 (71.4%) patients. The in-hospital mortality was 51.4%, and 1-year mortality was 60%. The discriminative power of Acute Physiology and Chronic Health Evaluation-II was excellent (area under the curve ≥0.9), and Intracerebral Haemorrhage Score was fair (area under the curve ≥0.7) for both in-hospital mortality and poor outcomes at discharge. The area under the curve of Acute Physiology and Chronic Health Evaluation-II was significantly higher than the area under the curve of Intracerebral Haemorrhage score. CONCLUSION: Acute Physiology and Chronic Health Evaluation-II score is a better model with high sensitivity and specificity than the Intracerebral Haemorrhage score in predicting the in-hospital mortality and functional outcomes at the discharge of spontaneous intracerebral haemorrhage patients. However, the Acute Physiology and Chronic Health Evaluation-II score lacks the neuroradiologic features that are crucial for spontaneous intracerebral haemorrhage. Therefore, the Intracerebral Haemorrhage score can be used as an indicator of neurological status combined with the Acute Physiology and Chronic Health Evaluation-II score rather than as a predictive model of outcomes.

Erector spinae plane catheter for pain management of multiple rib fractures: Anecdotal records of cases with blunt chest trauma.

High-energy chest wall traumas usually lead to multiple rib fractures associated with high morbidity and mortality. Pulmonary morbidity in patients with multiple rib fractures results from the impaired gas exchange from the pulmonary contusion areas and compromised breathing mechanics as a result of severe pain. Thus, analgesia plays a key role in the management of rib fractures. Erector spinae plane (ESP) block is a newly described technique and it has come into use in emergency departments for posterior rib fractures. ESP blocks can be administered in patients under anticoagulant therapy in the intensive care unit because the relevant area is located relatively superficial and far from the major vascular structures. In this report, anecdotal records of three patients with multiple rib fractures who had real benefits from ESP blocks are presented. This report highlights the bilateral extent of the sensory block after unilateral injection, the effect of ESP blocks on weaning from mechanical ventila-tion, and dramatic improvement in arterial blood gases analysis following ESP catheter insertion.

Assessment of inflammation with hematological parameters in patients with migraine and tension-type headache: a prospective study from a tertiary care center.

Aim: To investigate the role of inflammatory markers in patients with an acute headache attack. Materials & methods: This prospective controlled observational study comprised 150 subjects (migraine with aura [MA] n = 51, migraine without aura [MO] n = 51, tension-type headache n = 48, healthy controls n = 80). White blood cells (WBCs), neutrophil, lymphocyte and platelet counts, mean platelet volume, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were documented. Results: MA and MO constituted 14.2% of the admissions to the emergency department due to headaches. In addition, MA and MO had higher WBC and MO showed higher neutrophil count during the attacks than healthy control (p < 0.05). Conclusion: Although inflammatory parameters, including WBC and neutrophil counts, were high in headache patients, neutrophil-to-lymphocyte ratio did not show a significant rise. Clinical trial registration: NCT04891848.

Lay abstract Headache is one of the most common symptoms in patients admitted to emergency departments (ED). The vast majority of cases present with acute headache attacks in ED have a diagnosis of primary headache disorders, including tension-type headache (TTH) and migraine. Both of these headache types may contribute to a disabling process that decreases productivity and quality of life. Migraine is a chronic neurological disorder characterized by recurrent one-sided headache attacks with throbbing pain, lasting 4­72 h, accompanied by nausea and vomiting and sensitivity to light and/or sound. This disease usually manifests in the third­fourth decades of life, with female predominance. TTH is the most frequent type of primary headache disorder, characterized by mild to moderate pain with a 'pressing' or 'tightening' feeling lasting from 30 min to 7 days. Nausea or vomiting and sensitivity to light or sound are not seen with TTH. A relationship has been shown between these headache types and the number of cells in the blood, including red blood cells, white blood cells and platelets. In this study, we investigated the association of the number of blood cells in patients admitted to the ED with headache attacks and then compared the results of these patients with a healthy group of participants.

Application of unilateral rhomboid intercostal and subserratus plane block for analgesia after laparoscopic cholecystectomy: a quasi-experimental study.

BACKGROUND: Interfascial plane block can be used to treat postoperative pain after laparoscopic surgery. This study aimed to investigate the effect of ultrasound-guided unilateral rhomboid intercostal and subserratus plane (RISS) block after laparoscopic cholecystectomy on the amount of analgesic consumption. METHODS: Fifty patients who underwent laparoscopic cholecystectomy were included in this quasi-experimental study. Patients fulfilling the inclusion criteria were analyzed in two groups: RISS group (RISS block with 20 ml of 0.25% bupivacaine + intravenous patient-controlled analgesia [IV-PCA] tramadol [n = 25]); and Control group (IV-PCA tramadol [n = 25]). The primary outcome was the total amount of tramadol used over 24 h. Secondary outcomes included side effects, additional analgesic use, and postoperative pain (at rest and during activity) at 2, 6, 12, and 24 h according to numerical rating scale (NRS) scores. RESULTS: Postoperative tramadol consumption at 24 h was significantly lower in the RISS group than in the Control group (P < 0.001). Resting NRS scores at 2 h and 6 h were significantly lower in the RISS group. NRS scores during movement in the RISS group were significantly lower at 2, 6, and 12 h postoperatively. There was no statistically significant difference in the rate of side effects and additional analgesic use between the groups (P > 0.05). CONCLUSIONS: Unilateral RISS block was an effective method for pain management after laparoscopic cholecystectomy and can be used as a part of multimodal analgesia.

Prospective Evaluation of Infections in Geriatric Patients in Intensive Care Units.

Objective: Nosocomial infections (NIs) are major health problems with morbidity and mortality. Geriatric patients require intensive care unit (ICU) admission more frequently, and serious challenges occur during treatment. We aimed to evaluate the risk factors of NI and mortality in geriatric patients admitted to the ICU. Materials and Methods: The study was conducted between April 2018 and April 2019 in two hospitals. We prospectively recorded the data on the forms prepared according to daily ICU visits. Results: During the study period, 600 patients were hospitalized in the ICUs. Geriatric patients constituted 446 (74.3%) of the total number. The NI rate was 59% in adult patients and 80% in geriatric patients. The most frequent NI in geriatric patients was pneumonia (42%). Furthermore, the need for mechanical ventilation support, prolongation of hospital stay, total parenteral nutrition, and tracheostomy were statistically higher in geriatric patients with NI. The mortality rate in geriatric patients was statistically higher than in non-geriatric. We found the rates of prolonged hospitalization, NI development, malignancy, and cerebrovascular disease diagnosis significantly higher in geriatric patients than in non-geriatric patients. Conclusion: NI and mortality rate are higher in geriatrics than in adult patients. Pneumonia is the most common type of NI in the ICU. Identification of risk factors regarding NI and mortality in geriatric patients in ICU will contribute to developing strategies for prevention.

Ultrasonography-Guided Oblique Subcostal Transversus Abdominis Plane Block in Combination with Ultrasonography-Guided Rectus Sheath Block for Anaesthesia in Abdominal Wall Surgery.

Abdominal wall blocks provide considerable analgesia for relieving post-operative pain. Although they have been performed generally for post-operative pain management, abdominal wall blocks can be used as the principal anaesthesia method in certain cases. In this study, the case of a 47-year-old male patient who underwent surgical excisional biopsy for 2 vague intramuscular mass lesions (was within the rectus abdominis muscle and the other was within the transversus abdominis muscle) was presented. Ultrasonography (USG)-guided oblique subcostal transversus abdominis plane block in combination with USG-guided rectus sheath block was performed successfully as anaesthesia for the abdominal wall surgery. The intervention was performed fully under regional anaesthesia without any need for deep sedation or general anaesthesia.

Medical and surgical treatment of meralgia paresthetica.

Meralgia paresthetica (MP) is a painful mononeuropathy that causes paresthesia, tingling, stinging or a burning sensation in the thigh's anterolateral part due to the entrapment of the lateral femoral cutaneous nerve under the inguinal ligament. The treatment options for MP include conservative or interventional management and must follow an algorithm. The objective is to eliminate the underlying cause if known. In the present study, four patients with MP who were successfully treated with either conservative or interventional management are presented. The advantages and disadvantages of neurolysis (decompression and transposition) and neurectomy procedures for surgical treatments are discussed.

Lay abstract Meralgia paresthetica (MP) is a tingling, stinging or burning sensation on the thigh due to the compression of the nerve that gives sensation to the skin on the thigh. Constrictive clothing, obesity and pregnancy are common causes of MP. However, it can also be caused by local trauma or diseases such as diabetes. In most cases, MP can be treated with preventive measures such as wearing loose-fitting clothes and losing weight. In severe cases, treatment may require surgery.
