Ultrasound-guided erector spinae plane block in coronary artery bypass surgery: the role of local anesthetic volume-a prospective, randomized study.

BACKGROUND: Erector spinae plane block has been shown to help with pain management in different regions and many areas with different indications. However, the effectiveness of this block in cardiac surgery has been shown in the literature, the optimal volume remains unclear. The aim of this study is to determine the analgesic efficacy of two different volumes of local anesthetic injection used in ultrasound-guided bilateral-thoracic erector spinae plane block in patients undergoing coronary artery bypass graft. METHODS: This study was conducted on adult patients undergoing surgery with coronary artery bypass graft, and 70 patients were analyzed in each group. Group 20 received erector spinae plane block with 20 ml of 0.25% bupivacaine, Group 30 received 30 ml of 0.25% bupivacaine bilaterally. Postoperative sternotomy and chest tube-related pain were evaluated using the numerical rating scale (NRS) at rest and during movement. RESULTS: There were significant differences between the groups regarding rescue tramadol consumption was higher in Group 20 than in Group 30 (25/35 vs. 2/35, p < 0.001). In addition, there were substantial differences between the two groups concerning the time of the first-rescue analgesic requirement. The mean time ± standard deviation was 11.26 ± 9.57 h and 24.03 ± 4.12 h in Groups 20 and 30 (p < 0.001). The median scores, both at sternotomy and chest tubes, were significantly lower in Group 30 than in Group 20 at the different time points after the surgery (p < 0.05). CONCLUSIONS: In coronary artery bypass graft surgery, erector spinae plane block performed with 30 ml instead of 20 ml on each side resulted in less pain in the sternum and chest tube region, less need for rescue analgesics, and delayed first-rescue analgesic requirement.

The Shining Star of the Last Decade in Regional Anesthesia Part-II: Interfascial Plane Blocks for Cardiac, Abdominal, and Spine Surgery.

The sine qua non of enhanced recovery after surgery protocols designed to improve the perioperative experiences and outcomes of patients is to determine the most appropriate analgesia management. Although many regional techniques have been tried over the years in this purpose, interfacial plane blocks have become more popular with the introduction of ultrasound technology into daily practice and they have great potential to support effective postoperative pain management in many surgeries. The current article focuses on the benefits, techniques, indications, and complications of interfascial plane blocks applied in cardiac, abdominal, and spine surgeries.

Efficacy of transversalis fascia plane block as a novel indication for varicocelectomy surgery: prospective randomized controlled study.

BACKGROUND: Varicocele occurs as a result of dilatation of the pampiniform plexus in the spermatic veins. In this study, our primary aim was to evaluate the effect of Transversalis Fascia Plane Block (TFPB) on pain scores in the postoperative period in patients undergoing varicocelectomy surgery, and our secondary aim was to evaluate the effect of TFPB on analgesic consumption. METHODS: The study was initiated following local ethics committee approval, and sixty ASA I-II patients > 18y scheduled to undergo varicocelectomy and who consented to participation were enrolled. Before the procedure, the patients were randomly assigned two groups: Transversalis Fascia Plan block group (Group TFPB) or surgical incision site infiltration group (Group I).All surgeries were carried out under general anesthesia, and microsurgery using the subinguinal approach. After surgical suturing, TFPB and local infiltration blocks were applied prior to termination of anesthesia.For each block, 20 mL of 0.25% bupivacaine was utilized. Patients' demographic information, passive and active VAS ratings after surgery, usage of non steroidal anti-inflammatory medications and rescue analgesia, and the requirement for rescue analgesia, were recorded. RESULTS: A total of 60 patients were included in the study. In terms of demographic data, there was no difference between the groups. At all hours, there was a statistically significant decrease in favor of Group TFPB in terms of active and passive VAS scores (p < 0.001), non steroidal anti-inflammatory analgesic use (p < 0.05), and tramadol requirement (p < 0.001). CONCLUSION: This study has shown that TFPB can provide a more effective analgesia when compared to surgical site infiltration.

Ultrasound Guidance Pulsed Radiofrequency Ablation of the Medial Antebrachial Cutaneous Nerve for Palliation of Chronic Pain after Burn Injury: A Case Report.

Chronic burn pain persists for 6 months or longer after the wound has healed, affecting the patient's quality of life and daily activities. Pharmacological treatments are essential in the treatment of chronic pain after burns, but interventional methods come to the fore in cases where there is no response to pharmacological treatments. Radiofrequency ablation is known as a safe, effective, and minimally invasive treatment for patients with intractable chronic pain. Various pain syndromes can be successfully treated with radiofrequency ablation however, there is no publication of chronic pain management associated with burn injury. Here, we first describe the successful management of chronic burn pain using radiofrequency ablation of the medial antebrachial cutaneous nerve.

Effect of Aortic Cross-Clamping Time on Development of Postoperative Atrial Fibrillation in Isolated CABG: A Single-Center Prospective Clinical Study

ABSTRACT Introduction: Many etiological factors affect the occurrence of atrial fibrillation after coronary artery bypass grafting. In this study, the relationship between cardiopulmonary bypass and cross-clamping times and the development of postoperative atrial fibrillation was examined. Methods: All patients who underwent isolated coronary artery bypass grafting with the same surgical team in our clinic between September 2018 and December 2019 were prospectively included in the study, and their perioperative data were recorded. Results: One hundred and three patients who met the specified criteria were included in the study. The median age was 62 (interquartile range: 54-71) years, and 82 (79.6%) were male. The patients were divided into two groups: those who developed atrial fibrillation and those who did not. Atrial fibrillation developed in 25 of 103 patients (24.3%). All patients underwent isolated coronary artery bypass grafting under standard cardiopulmonary bypass. The median duration of cardiopulmonary bypass was 72 (interquartile range: 63-97) minutes in those with atrial fibrillation and 82 (61-98) minutes in those without it, and there was no statistical difference (P=0.717). The median cross-clamping time was 40 (32.5-48) minutes in those with atrial fibrillation and 39.5 (30-46) minutes in those without it. Statistically, the relationship between cross-clamping time and atrial fibrillation was not significant (P=0.625). Conclusion: Our study found no significant relationship between cardiopulmonary bypass and cross-clamping times and the incidence of postoperative atrial fibrillation. However, we believe that there is a need for large-scale and multicenter clinical studies on the subject.

Myocardial Protection in Cardiac Surgery: Exploring the Influence of Anesthetic Agents.

This review assesses the efficacy of inhalation anesthetics and propofol in cardiac surgery, primarily focusing on their impact on myocardial protection and subsequent clinical outcomes. The review provides a concise summary of the current scientific information regarding the protective efects of inhalation anesthetics and propofol, particularly in the context of ischemia-reperfusion injury during cardiac surgery. The review delves into the mechanisms of action and discusses clinical studies comparing the 2 anesthetic strategies regarding mortality, complication rates, and length of hospital stay. Inhalation anesthetics exhibit cardioprotective properties through many mechanisms, such as preconditioning, scavenging of free radicals, and stabilizing mitochondria. Propofol demonstrates certain protective benefits but does not possess the preconditioning capability of inhalation medications. Clinical investigations yield contradictory findings, as several studies indicate enhanced outcomes with inhalation anesthetics, while others observe no substantial disparity between the 2 approaches. The cardioprotective efcacy of propofol against ischemia-reperfusion injury remains limited. While its inherent antioxidant properties ofer direct myocardial protection, propofol demonstrably lacks the preconditioning-mediated signaling pathways triggered by inhalation anesthetics. As a result, propofol's protective efect may be slightly inferior to preconditioning strategies, and its potential to inhibit organ-protective impact of other interventions needs further investigation. The question of which anesthetic approach ofers superior myocardial protection remains debatable. Current evidence is inconclusive, potentially due to patient heterogeneity, surgical complexity, and methodological limitations of existing studies. Future research, including pharmacogenetic studies and large, welldesigned, randomized controlled trials, are necessary to provide definitive guidance on anesthetic selection for optimal myocardial protection in cardiac surgery.

Intravenous lidocaine vs. NSAIDs for migraine attack in the ED: a prospective, randomized, double-blind study.

PURPOSE: Although different forms of lidocaine are used for migraine attack headaches, the effect of intravenous lidocaine is still limited. This study aimed to investigate the effects of intravenous lidocaine infusion for the treatment of migraine attack headaches. METHODS: A hundred patients with migraine attacks, aged between 18 and 65, were randomly divided into two groups. The lidocaine group (n = 50) received a 1.5 mg/kg lidocaine bolus and a 1 mg/kg infusion (first 30 min), followed by a 0.5 mg/kg infusion for a further 30 min intravenously. The non-steroidal anti-inflammatory drug (NSAID) group (n = 50) received 50 mg dexketoprofen trometamol and saline at the same volume as the lidocaine at the same time intervals intravenously. The Visual Analog Scale (VAS) pain scores, additional analgesia requirement, side effects, and revisits to the emergency department were recorded. RESULTS: The VAS score was significantly lower in the lidocaine group than in the NSAID group for the first 20th and 30th minutes (p = 0.014 and p = 0.024, respectively). There was no difference between the VAS scores for the remaining evaluation times (p > 0.05). In terms of secondary outcomes, rescue medication requirement was not different between the two groups at both the 60th and 90th minutes (p > 0.05). However, the number of patients revisiting ED within 48-72 h was statistically less in the lidocaine group than in the NSAID group (1/50 vs. 8/50; p = 0.031). CONCLUSION: Intravenous lidocaine may be an alternative treatment method for patients with migraine attack headaches in the emergency department.

The Shining Star of the Last Decade in Regional Anesthesia Part-I: Interfascial Plane Blocks for Breast, Thoracic, and Orthopedic Surgery.

Regional anesthesia has benefits beyond just treating acute postoperative pain. Interfascial plane blocks, which have been very popular with ultrasound in recent years, function primarily by administering a high volume of a local anesthetic to the fascial plane. Contrary to traditional peripheral nerve blocks, the targeted nerve or structure in interfacial plane blocks is not fully defined, and the indications have not been fully revealed yet. Anatomical, cadaveric, and radiological studies show how effective the interfascial plane blocks play a role. This review focuses on the benefits, techniques, indications, and complications of interfascial plane blocks in the context of breast, thoracic, and orthopedic surgery.

New description of vagal nerve commanted intrapancreatic taste buds and blood glucose level: An experimental analysis.

Introduction: There have been thousands of neurochemical mechanism about blood glucose level regulation, but intrapancreatic taste buds and their roles in blood glucose level has not been described. We aimed to investigate if there are taste buds cored neural networks in the pancreas, and there is any relationship between blood glucose levels. Methods: This examination was done on 32 chosen rats with their glucose levels. Animals are divided into owned blood glucose levels. If mean glucose levels were equal to 105 ± 10 mg/dL accepted as euglycemic (G-I; n = 14), 142 ± 18 mg/dL values accepted as hyperglycemic (G-II; n = 9) and 89 ± 9 mg/dL accepted as hypoglycemic (G-III; n = 9). After the experiment, animals were sacrificed under general anesthesia. Their pancreatic tissues were examined histological methods and numbers of newly described taste bud networks analyzed by Stereological methods. Results compared with Mann-Whitney U test P < 0.005 considered as significant. Results: The mean normal blood glucose level (mg/dL) and taste bud network densities of per cm3 were: 105 ± 10 mg/dL; 156±21 in G-I; 142 ± 18 mg/dL and 95 ± 14 in G-II and 89 ± 9 mg/dL and 232 ± 34 in G-III. P values as follows: P < 0.001 of G-II/G-I; P < 0.005 of G-III/G-I and P < 0.0001 of G-III/G-II. We detected periarterial located taste buds like cell clusters and peripherally located ganglia connected with Langerhans cells via thin nerve fibers. There was an inverse relationship between the number of taste buds networks and blood glucose level. Conclusion: Newly described intrapancreatic taste buds may have an important role in the regulation of blood glucose level.

Does intravenous lidocaine added to nonsteroidal anti-inflammatory drugs reduce pain during colposcopy? A prospective randomized double-blind study.

OBJECTIVES: In recent years, lidocaine infusion for pain management during long operations is becoming more widespread in anesthesiology practice. However, only a limited number of studies have reported the intravenous use of lidocaine for short-term interventions. The aim of this study was to investigate the effectiveness of intravenous lidocaine use in pain management during colposcopic cervical biopsy and endocervical curettage (ECC). MATERIAL AND METHODS: Patients between the ages of 18 and 65 years with abnormal cytological findings or who were determined to be human papillomavirus (HPV)-positive were included in this randomized double-blind study. The lidocaine group (Group L, n = 30) was intravenously administered 50 mg dexketoprofen + 1.5 mg/kg lidocaine in 10 mL saline for 3 min 30 min before the procedure. The control group (Group C, n = 30) was intravenously administered 50 mg dexketoprofen in 10 mL saline for 3 min, 30 min before the procedure. During the procedure, pain scores were assessed using the visual analogue scale (VAS). In addition, patients, operator satisfaction and duration of procedure were assessed. RESULTS: There were no differences in the demographic data of the groups. Pain scores during biopsy and ECC were significantly lower in Group L than in Group C (p < 0.001). The duration of the procedure was significantly shorter in Group L than in Group C (5.00 ± 0.78 vs 6.12 ± 1.16, respectively; p < 0.001). Patient and operator satisfaction were significantly higher in Group L than in Group C (p < 0.001). CONCLUSIONS: Intravenous lidocaine administration can be used as an alternative approach to reduce pain and increase operator and patient satisfaction during colposcopy-directed biopsy and ECC procedures in office settings.

First emerging evidence of the relationship between Onuf's nucleus degeneration and reduced sperm number following spinal subarachnoid haemorrhage: Experimental study.

Lumbosacral pathologies can lead to infertility. Onuf's nucleus changes in these pathologies may have a role in low sperm number. This study aims to investigate the relationship between Onuf's nucleus degeneration and sperm number following spinal subarachnoid haemorrhage. 22 rabbits were used. They were divided into three groups; five of them were used as the control (GI), five as the SHAM (GII) and twelve as the study groups (GIII). The study group received 0.7 ccs autologous blood into the spinal subarachnoid space at the T12-L1 level. After two weeks, all animals were decapitated, and S1-S3 laminectomy was done. Neurodegenerative changes of Onuf's nucleus, pudendal ganglia (S3) following two weeks after spinal SAH, were examined; sperm numbers were calculated. Degenerated neuron density of the Onuf's nucleus (n/mm3 ), the pudendal ganglia (S3) (n/mm3 ) and mean sperm numbers were calculated as 5 ± 2, 8 ± 3/mm3 and 98.345 ± 12.776/mm3 in the control (GI), 20 ± 5/mm3 , 243 ± 66/mm3 and 91.841 ± 9.654/mm3 in the SHAM (GII), 143 ± 39/mm3 , 2,350 ± 320/mm3 and 68.549 ± 5.540/mm3 in the study group (GIII). In conclusion, there were statistically significant differences between groups. Onuf's nucleus may be responsible for decreased sperm number following spinal SAH.

Destructive Effects of Acidic Blood on the Intestines: Experimental Study.

OBJECTIVE: This study aimed to investigate the destructive effects of acidic blood on the intestinal structures, which has been reported as the most hazardous biochemical result of vagosympathetic autonomic imbalances in intensive care unit patients with subarachnoid hemorrhage (SAH). MATERIALS AND METHODS: In total, 27 hybrid rabbits were used; 5 rabbits were used as a control group, 7 as the SHAM group into whom 1 cc saline was injected into the cisterna magna, and the remaining 15 were used as the study group. These animals received 1 cc of autologous arterial blood injection into the cisterna magna to create the SAH group. Blood pH values were recorded before, during, and after the experimental procedures. Computed tomography was performed to examine the intestinal morphology. Normal and degenerated epithelial cell densities of the intestine were estimated by stereological methods. The relationship between pH values and intestinal tissue changes was analyzed statistically using the Mann-Whitney U test. RESULTS: The mean blood pH values were 7.364±0.042 in the control group, 7.326±0.059 in the SHAM group, and 7.23±0.021 in the study group. Intestinal epithelial cell injury, desquamation of villus, and cell loss were observed. It is observed that the number of degenerated epithelial cells, fragmented villi numbers, and vacuoles significantly increased in the study group (p<0.05). CONCLUSION: Acidotic intestinal injury secondary to blood pH changes following SAH may be considered as a generalized and dangerous complication with their multiorgan insuficiency effect.

Postoperative analgesic effectiveness of ultrasound-guided transmuscular quadratus lumborum block in congenital hip dislocation surgery : A randomized controlled study.

BACKGROUND/OBJECTIVE: Congenital hip dysplasia (CHD) defines a spectrum of pathologies in which the acetabulum and proximal femur of babies and children abnormally develop. Open surgery in congenital hip dysplasia leads to severe postoperative pain. The aim of this study was to evaluate the effectiveness of ultrasound-guided quadratus lumborum block (QLB) in pediatric patients undergoing surgery for congenital hip dysplasia. MATERIAL AND METHODS: Following ethical board approval, 40 children aged between 1-5 years undergoing surgery for congenital hip dysplasia were randomized into two groups. Patients (n = 20) received ultrasound guided quadratus lumborum block (group QLB) using 0.5 mL/kg body weight 0.25% bupivacaine preoperatively. The same standard postoperative analgesia protocol was used in both groups. Pain scores, parental satisfaction, requirement for ibuprofen and opioids were recorded. Pain was measured using the face, legs, activity, crying, consolability (FLACC) scale. RESULTS: The FLACC scores were lower at 30min and 1h, 2h, 4h, 6h, 12h and 24h in the QLB group when compared to the control group (p < 0.05). The requirement for rescue opioid analgesia was statistically significantly higher in the control group when compared to the QLB group (15/20 vs. 3/20, p < 0.001). Rate of ibuprofen usage in the ward was higher in the control group when compared to the QLB group (14/20 vs. 4/20, p = 0.004). Parental satisfaction was higher in the QLB group (p < 0.001). CONCLUSION: Ultrasound-guided quadratus lumborum block reduces pain scores and analgesic requirements following congenital hip dysplasia surgery.

Can ultrasound-guided infraclavicular block be an alternative option for forearm reduction in the emergency department? A prospective randomized study.

OBJECTIVE: Ultrasound-guided infraclavicular nerve block (IB) has become a well-established method in several outpatient procedures; however, its use in emergency departments (EDs) remains limited. The aim of this study was to compare procedural sedation and anlagesia (PSA) and IB in the pain management for patients who underwent forearm fracture reduction in the ED. METHODS: This prospective randomized study included 60 patients aged 18 to 65 years, who visited the ED with forearm fractures. They were randomly divided into two groups: Group PSA (n=30) and Group IB (n=30). The pain scores of patients were evaluated before and during the procedure with the visual analog scale. Complications and patient and operator satisfaction levels were recorded. RESULTS: There was no difference between the two groups in terms of demographic characteristics. The median (interquartile range) pain scores observed during the procedures were significantly higher in Group PSA than in Group IB (4 [4-6] vs. 2 [0-2], respectively; P<0.001). Patient and operator satisfaction levels were significantly higher in Group IB (P<0.001). Oxygen desaturation was statistically higher in Group PSA than in Group IB (40.00% vs. 3.33%, respectively; P=0.002). CONCLUSION: IB was an effective alternative for reducing pain and increasing patient satisfaction in ED patients undergoing forearm fracture reduction.

Perioperative Intravenous Low-Dose Ketamine Infusion to Minimize Pain for Septorhinoplasty: A Prospective, Randomized, Double-Blind Study.

OBJECTIVES: Studies investigating the effects of intravenous (IV) ketamine in pain management after septorhinoplasty is limited. This study aims to evaluate the efficacy of low-dose IV infusion of ketamine on pain scores. METHODS: This randomized, prospective, double-blind study was conducted with 48 patients who underwent septorhinoplasty. Intravenous ketamine bolus (0.5 mg/kg) was administered to the ketamine group (group K, n = 24) at anesthesia induction, and ketamine infusion was continued (0.25 mg/kg/h) during the surgery. In the control group (group C, n = 24), the same protocol was administered using saline instead of ketamine. Furthermore, 50-mg dexketoprofen trometamol was administered to both groups 30 minutes before the end of the surgery. Then it was repeated at the 12th and 24th hours postoperatively. Pain scores were evaluated with the visual analogue scale. Consumptions intraoperative of opioid and sevoflurane, rescue opioid requirement, patient satisfaction, and side effects were recorded. RESULTS: Pain scores were significantly lower in group K at all postoperative periods (P < .05). There was no significant difference between the groups in terms of intraoperative sevoflurane and remifentanil consumptions (P > .05). Rescue opioid analgesic requirements were significantly lower in group K than group C (0/24 vs 6/24, respectively; P  = .022). Side effects were similar between the groups (P > .05). CONCLUSION: We recommend the administration of low-dose ketamine infusion during septorhinoplasty surgery because it reduces the requirement for rescue opioid analgesia and postoperative pain scores.

Pre-procedure intravenous lidocaine administration on propofol consumption for endoscopic retrograde cholangiopancreatography: A prospective, randomized, double-blind study.

BACKGROUND AND AIM: The endoscopic retrograde cholangiopancreatography (ERCP) procedure is generally performed in patients with high comorbidity. We aimed to reduce the consumption of propofol by adding lidocaine before ERCP. METHODS: Eighty ERCP patients with ASA I-III, aged between 45-75 years, were randomly divided into two groups. Lidocaine group (group L, n = 40), received 1-mg midazolam, 1.5 mg/kg lidocaine, and 1 mg/kg propofol intravenously. The control group (group C, n = 40) received 1-mg midazolam, saline in the same volume as the lidocaine group, and 1 mg/kg propofol intravenously. Propofol was administered with intermittent bolus doses. Propofol consumption, oropharyngeal reflex, recovery time, endoscopist satisfaction, ketamine need, and side-effects were recorded. RESULTS: Propofol consumption during the procedure was statistically lower in group L than in the control group (157.25 ± 39.16 mg vs 228.75 ± 64.62 mg respectively, P < 0.001). Additionally, recovery time was statistically faster in group L compared with the control group (7.78 ± 3.95 min vs 11.92 ± 3.24 min respectively, P < 0.001). The oropharyngeal reflex was less in group L than control group (6/40 vs 15/40 respectively, P = 0.042). There was no significant difference between the two groups regarding visual analogue scale scores and endoscopist satisfaction (P > 0.05). CONCLUSIONS: We recommend the use of intravenous lidocaine before the ERCP procedure as it reduces propofol consumption, recovery times, and oropharyngeal reflex.

Sedoanalgesia Versus Infraclavicular Block for Closed Reduction of Pediatric Forearm Fracture in Emergency Department: Prospective Randomized Study.

OBJECTIVE: Procedural sedoanalgesia is commonly used in pediatric patients in the emergency department (ED) for interventional procedures, diagnosis, and treatment. However, this method causes serious systemic complications, such as respiratory and cardiac depression. To minimize these complications, ultrasound-guided regional anesthesia methods have been used in recent years. We aimed to compare the use of procedural sedoanalgesia (PSA) and infraclavicular block (ICB) in the pain management of pediatric patients who underwent closed reductions of forearm fractures. MATERIALS AND METHODS: This prospective, randomized, clinical study included patients aged 3 to 15 years who presented to the ED with forearm fractures. The patients were divided into 2 groups: the procedural sedoanalgesia group (group PSA, n = 30) and ultrasound-guided ICB group (group ICB, n = 30). Pain scores of the patients were evaluated using the Wong-Baker FACES Scale before and during the procedure. Pain scores and parental and operator satisfaction were compared between the groups. RESULTS: There was no statistical significance in terms of demographic data. The pain scores observed during the procedures were significantly higher in the group PSA than in the group ICB (3.07 ± 1.55 vs 0.47 ± 0.86, respectively; P < 0.001). The parental and operator satisfaction of the ICB group was significantly higher than that of the PSA group (P < 0.001). CONCLUSIONS: Ultrasound-guided ICB is a safe and effective method in the management of pain during closed reduction of forearm fracture in pediatric patients in EDs. It can be used safely in emergency rooms and has a high level of both parental and operator satisfaction.

Erector spinae plane block vs non-steroidal anti-inflammatory drugs for severe renal colic pain: A pilot clinical feasibility study.

AIM: Ultrasound-guided plane blocks are increasingly used in the multi-modal analgesic concept for reducing opioid consumption. The present study was conducted to compare the analgesic effect of intravenous non-steroidal anti-inflammatory drugs (NSAIDs) and erector spinae plane (ESP) block in renal colic patients. METHODS: In this prospective randomised study, 40 patients with renal colic pain were randomly assigned into two groups: Group NSAID (n = 20) received an intravenous infusion of 50 mg of dexketoprofen trometamol and Group ESP (n = 20) received ultrasound-guided ESP block with 30 ml 0.25% bupivacaine at the T8 level. The pain severity of patients was assessed using the visual analogue scale (VAS) at baseline, 5, 15, 30, 45 and 60 minutes after intervention. Opioid consumption, patient satisfaction and side effects were recorded. RESULTS: In the ESP group, the VAS scores were significantly lower than the NSAID group at 5, 15, 30, 45 and 60 minutes after the procedure (P < .001). Opioid consumption was significantly higher in the NSAID group compared with the ESP group (10/20 vs 0/20, respectively; P < .001). Patient satisfaction was significantly higher in the ESP group (P < .001). CONCLUSIONS: ESP block can be an alternative, efficient and safe method for the relief of acute renal colic pain.
