RESUMO
BACKGROUND: 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. OBJECTIVE: We aimed to compare the impact of these two blocks on the quality of recovery in patients undergoing elective caesarean section under spinal anaesthesia. DESIGN: A single-centre, double-blind, randomised trial. SETTINGS: Operating room, postanaesthesia recovery unit, and ward in a tertiary hospital. PARTICIPANTS: 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. INTERVENTIONS: After surgery, participants received either TFP block (20âml 0.25% bupivacaine for each side) or TAP block (20âml 0.25% bupivacaine for each side). MAIN OUTCOME MEASURES: 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. RESULTS: The mean ObsQoR-11T score was higher in the TFP block group compared with the TAP block group (97.13â±â6.67 points vs. 87.10â±â9.84 points, respectively; Pâ<â0.001). The pain scores in the TFP block group were slightly lower between postoperative 4 and 24âh. The mean total morphine consumption was 15.08â±â2.21âmg in the TFP block group and 22.21â±â3.04âmg in the TAP block group (Pâ<â0.001). More patients required rescue analgesia between 4 and 8âh in the TAP block group [2.00 (5.00%) vs. 9.00 (23.08%), Pâ=â0.02]. No significant differences were observed between groups in terms of opioid-related side effects. CONCLUSION: TFP block used for analgesic purposes yielded a better quality recovery period than TAP block and also reduced opioid consumption. TRIAL REGISTRATION: Clinicaltrials.gov (NCT05999981).

RESUMO
BACKGROUND: Laparoscopic cholecystectomy(LC) causes significant postoperative pain. Oblique subcostal transversus abdominis plane(OSTAP) block was described for postoperative analgesia, especially for upper abdominal surgeries. Modified thoracoabdominal nerves block through perichondrial approach(M-TAPA) block is a new technique defined by the modification of the thoracoabdominal nerves through perichondrial approach (TAPA) block, in which local anesthetics are delivered only to the underside of the perichondral surface. The primary aim of this study was to evaluate the effect of M-TAPA and OSTAP blocks as part of multimodal analgesia on postoperative opioid consumption in patients undergoing LC. METHOD: The present study was designed as a randomized, controlled, prospective study. Seventy-six adult patients undergoing LC were randomly assigned to receive either bilaterally M-TAPA or OSTAP block after the induction of anesthesia and before surgery using bupivacaine 0.25%, 25 ml. The primary outcome was assessed as postoperative 24 h opioid consumption, between groups were compared. Secondary outcomes were Numerical Rational scale(NRS) scores, time to first opioid analgesia, patient recovery, using the Quality of Recovery-15 (QoR-15) scale, nausea and vomiting, sedation score, metoclopramide consumption, and evaluating the analgesic range of dermatome. RESULTS: The mean tramadol consumption at the postoperative 24th hour was higher in the group OSTAP than in group M-TAPA (P = 0.047). NRS movement score at 12th hour was statistically significantly lower in group M-TAPA than in group OSTAP (P = 0.044). Dermatomes showed intense sensory analgesia between T7-11 in both groups, and it was determined that there was proportionally more involvement in the group M-TAPA. There were no differences between the groups in terms of other results. CONCLUSIONS: After the LC surgery, ultrasound-guided M-TAPA block effectively reduced opioid consumption, postoperative pain, and QoR-15 scores similar to OSTAP block. CLINICAL TRIAL REGISTRATION: The study was registered prospectively at clinicaltrials.gov (trial ID: NCT05108129 on 4/11/2021).

Background and purpose: Multiple sclerosis is an autoimmune disease of the central nervous system, with myelin degeneration and Relapsing-Remitting Multiple Sclerosis (RRMS) as the most common type. The aim of this study was to determine the levels of Neurofilament Light Chain (NFL) and Orexin-A (OXA) in patients with RRMS and compare it with healthy control subjects' data. Methods: In this case-control study of 61 subjects, serum and cerebrospinal fluid samples were collected from 23 RRMS patients and 38 healthy control subjects. NFL and OXA levels were determined in cerebrospinal fluid and serum samples using enzyme-linked immunosorbent assay kits. Self-reported questionnaires were also administered to evaluate fatigue severity and impact. Receiver operating characteristic curve analysis was used to determine the optimal cut-off value of NFL and OXA. Results: The NFL and OXA concentrations in cerebro-spinal fluid of RRMS patients were significantly higher than those of the control group (p < 0.001), but no sig-nificant difference was found in the serum concentrations (p = 0.842, p = 0.597, respectively). The cut-off values were found to be 1.194 ng/ml for NFL and 77.81 pg/ml for OXA in cerebrospinal fluid. A positive correlation was found between the Expanded Disability Status Scale and Epworth Sleepiness Scale in RRMS patients (ρ = 0.49, p = 0.045). Conclusion: These results suggest that increased levels of both NFL and OXA in cerebrospinal fluid reflect neuronal destruction in RRMS. Further research of neurodegeneration should focus on neuropeptides to determine the possible roles in RRMS pathogenesis.

BACKGROUND: A mouth gag is usually used during tonsillectomy and adenotonsillectomy surgeries, cleft palate repair, obstructive sleep apnea surgery, and intraoral tumor excision. The placement of the gag causes hemodynamic changes similar to laryngoscopy. The aim of this study was to evaluate the effect of mouth gag placement on the optic nerve sheath diameter (ONSD) of pediatric patients. The secondary aim was to assess the relationship between neck extension and changes in ONSD. METHODS: The trial was prospectively registered to the Australian New Zealand Clinical Trials Registry (Trial ID: ACTRN12618000551291) on 12.04.2018. This prospective, observational study was performed in a tertiary university hospital operating room between 01.05.2018-01.07.2018. Thirty-five children aged < 18 years, with ASA I status, who were scheduled for tonsillectomy and adenotonsillectomy surgeries were prospectively included in the study. Measurements of ONSD were performed (T0) after induction of anesthesia, (T1) after endotracheal intubation, (T2) after mouth gag placement, and (T3) 20 min after mouth gag placement. After the mouth gag was placed and the head was positioned for surgery, the degree of neck extension was calculated. RESULTS: All participants completed the study. There were significant differences in ONSD values at time points T1, T2, and T3 (p < 0.001, CI: - 0.09,-0.05; p < 0.001, CI: - 0.09,-0.05; p < 0.001, CI: - 0.05,-0.02; respectively). The maximum increase in ONSD was after intubation (0.69 ± 0.06 mm) and immediately after mouth gag placement (0.67 ± 0.07 mm). ONSD values continued to increase 20 min after gag placement (0.36 ± 0.04). There was no relation between the degree of neck extension and ONSD values (ß = 0.63, p = 0.715). CONCLUSIONS: The use of a mouth gag causes significant increases in ONSD measurements of children. Therefore, attention to the duration of mouth gag placement should be considered during surgery. TRIAL REGISTRATION: The trial was prospectively registered to the Australian New Zealand Clinical Trials Registry (Trial ID: ACTRN12618000551291 ) on 12.04.2018.

BACKGROUND: The mean platelet volume (MPV) is an important indicator of platelet function with large platelets showing higher enzymatic and metabolic activity than other platelets. There can be a relationship between increased platelet activity and anxiety and depression. Our primary hypothesis was that patients with high anxiety scores would have higher MPV, and the secondary hypothesis was that propofol induction time and total propofol consumption within the first 30 min of surgery would be higher in patients with higher anxiety scores. METHODS: The Beck Anxiety Inventory (BAI) was administered to the participating patients 1 day before surgery to evaluate the level of anxiety. Based on the scores from the BAI, 40 patients with an anxiety score of < 8 were assigned to the non-anxious group (Group NA) and 40 patients with an anxiety score of ≥8 were assigned to the anxious group (Group A). At the anesthesia induction the mean time to achieve an entropy value below 60 (T1) was recorded. The total intraoperative propofol consumption within the first 30 min was recorded. RESULTS: There was a statistically significant difference between the groups in terms of preoperative MPV and demographic data, including age and sex. The mean total propofol consumption at 30 min after induction in the groups was statistically significant. The cut-off value for MPV was calculated as 9.65. CONCLUSIONS: The preoperative MPV values and propofol consumption at 30 min among patients with high preoperative anxiety scores were high. We suggest that MPV is helpful in the clinical practice in predicting the amount of anesthetic agents required for the 30 mins of anesthesia.

BACKGROUND: Breast cancer surgery is one of the most common surgeries among the female population. Nearly half of the patients suffer chronic pain following breast cancer surgery, and 24% of them categorizing their pain as moderate to high. In this study, effects of ultrasound-guided erector spinae plane (ESP) block performed using two different concentrations of bupivacaine on postoperative tramadol consumption, pain scores, and intraoperative fentanyl requirements among patients who underwent radical mastectomy surgery were compared. METHODS: This double-blinded, prospective, and randomized study included patients with age ranged 18-70, American Society of Anesthesiologist physical status I-II, and scheduled for unilateral modified radical mastectomy surgery. The patients were randomly allocated into two groups. In group I, ESP block was performed with 0.375% bupivacaine. In group II, ESP block was performed with 0.25% bupivacaine. General anesthesia was induced in both groups according to the standard procedures. When the pain score was ≥4, patients received intravenous (i.v.) 25 mcg fentanyl in the recovery room or 4 mg of morphine in the surgical ward as a rescue analgesia. The main measurements were postoperative tramadol consumption; Numerical Rating Scale (NRS) scores 15, 30, and 60 min and 12 and 24 h postoperatively; and intraoperative fentanyl requirements. RESULTS: In total, 42 patients (21 patients in each group) were included in the study. The mean tramadol consumption at the postoperative 24th h was 149.52 ± 25.39 mg in group I, and 199.52 ± 32.78 mg in group II (p = 0.001). In group I, the NRS scores were significantly lower at every time points compared with those in group II. The mean intraoperative fentanyl requirement was similar in the two groups. CONCLUSION: Although ESP block performed with both concentrations of bupivacaine provided effective postoperative analgesia, the higher concentration of bupivacaine significantly reduced postoperative tramadol consumption after radical mastectomy surgery. CLINICAL TRIAL REGISTRATION: The study was registered prospectively with the Australian New Zealand Clinical Trials Registry (trial ID: ACTRN12618001334291at 08/08/2018).

OBJECTIVE: In obstetric patients' airway, guidelines have recommended the availability of advanced airway equipment. Our aim was to compare the larynx visualization provided by the Macintosh direct laryngoscope and McGrath video laryngoscope and the intubation time of patients undergoing cesarean section. METHODS: This study was conducted at a private obstetrics and gynecology hospital during one month between June and July 2018. A hundred patients scheduled for elective cesarean section under general anesthesia were randomized into two different group's as intubated using either McGrath VL or Macintosh DL. The intubation times, Cormack-Lehane grade, percentage of glottic opening, mean arterial blood pressure, and heart rates before and after intubation were compared among the groups. RESULTS: The McGrath VL significantly reduced the intubation time compared to the Macintosh DL. In the McGrath VL group, better glottic view set the time of tracheal intubation as assessed using the Cormack-Lehane classification system and POGO scores were recorded. After intubation, hemodynamic parameters were significantly higher in the Macintosh DL group than in the McGrath VL group. CONCLUSION: The McGrath VL significantly lowered intubation time relative to the Macintosh DL, which may be a critical finding considering the importance of maintaining the mother's airway for the health of both mother and baby.
RESUMO
PURPOSE: The primary outcome of this study is to compare the success rates of ONB techniques performed either with ultrasound guidance or with the blind technique. The second outcome is to compare the incidences of perioperative bleeding and the presence of recurrent tumors in the control cystoscopy performed in the 3rd postoperative month in both groups. MATERIALS AND METHODS: The study was conducted in the urology operating room of Mugla Sitki Kocman Training and Research Hospital between December 2019 and March 2023. A total of 122 patients were included in the study: 22 females with a mean age of 56.63 ± 12.99 years and 100 males with a mean age of 63.18 ± 8.00 years. In one group (group 1), ONB was performed under ultrasound guidance by the same anesthesiologist, and in another group (group 2), ONB was performed blindly based on anatomical signs by the same urologist. RESULTS: Adductor muscle contraction was not observed in 53 patients (91.4%) in group 1 and in 49 patients (76.6%) in group 2 (p = 0.027). CONCLUSION: The success rate of ONB was higher when using an ultrasound-guided technique than when using a blind technique.
RESUMO
OBJECTIVES: To compare the genotoxic effects of desflurane and propofol using comet assay in patients undergoing elective discectomy surgery. METHODS: This was a randomized controlled study. Patients who underwent elective lumbar discectomy under general anesthesia with propofol or desflurane were included in the study. Venous blood samples were obtained at 4 different time points: 5 minutes before anesthesia induction (T1), 2 hours after the start of anesthesia (T2), the first day after surgery (T3), and the fifth day following surgery (T4). Deoxyribonucleic acid damage in lymphocytes was assessed via the comet assay. RESULTS: A total of 30 patients, 15 in each group, were included in the analysis. The groups were similar in terms of age and gender distribution. There were no significant differences in demographics, duration of surgery, total remifentanil consumption, and total rocuronium bromide consumption. The comet assay revealed that head length, head intensity, tail intensity, tail moment at T1 were similar in the desflurane and propofol groups. Head length, tail length and tail moment measured in the desflurane group at T4 were significantly higher compared to the propofol group. Tail lengths of the desflurane group at T1, T2 and T3 were significantly higher than the corresponding values in the propofol group. CONCLUSION: Propofol and desflurane do not appear to induce DNA damage in lymphocytes. However, when the quantitative data were compared, it was determined that propofol had relatively lower genotoxic potential than desflurane.ClinicalTrials.gov Reg. No.: NCT05185167.

BACKGROUND: Reduced lumbar lordosis may make the process of identifying the intervertebral distance easier. The primary aim of this study was to measure the L3...L4 intervertebral space in the same patients undergoing spinal anesthesia in three different sitting positions, including the classic sitting position (CSP), hamstring stretch position (HSP) and rider sitting position (RSP). The secondary aim was to compare ultrasonographic measurements of the depth of the ligamentum flavum and intrathecal space in these three defined positions. METHODS: This study is a single-blinded, prospective, randomized study. Ninety patients were included in final analysis. the patients were positioned on the operating table in three different positions to perform ultrasonographic measurements of the spinal canal. The intervertebral distance (IVD), the distance between the skin and the ligamentum flavum (DBSLF) and the intrathecal space (IS) were measured in the L3...L4 intervertebral space in three different positions. RESULTS: The RSP produced the largest mean distance between the spinous processes. The RSP yielded a significantly larger IVD than did the CSP (p < 0.001) and HSP (p < 0.001). The DBSP was larger in the CSP than in the HSP (p = 0.001). The DBSLF was significantly larger in the RSP than in the HSP (p = 0.009). CONCLUSIONS: Positioning the patient in the RSP significantly increased the intervertebral distance between L3...L4 vertebrae compared to the CSP and HSP, suggesting easier performance of lumbar neuraxial block.

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.
RESUMO
BACKGROUND: Inconsistent nomenclature and anatomical descriptions of regional anesthetic techniques hinder scientific communication and engender confusion; this in turn has implications for research, education and clinical implementation of regional anesthesia. Having produced standardized nomenclature for abdominal wall, paraspinal and chest wall regional anesthetic techniques, we aimed to similarly do so for upper and lower limb peripheral nerve blocks. METHODS: We performed a three-round Delphi international consensus study to generate standardized names and anatomical descriptions of upper and lower limb regional anesthetic techniques. A long list of names and anatomical description of blocks of upper and lower extremities was produced by the members of the steering committee. Subsequently, two rounds of anonymized voting and commenting were followed by a third virtual round table to secure consensus for items that remained outstanding after the first and second rounds. As with previous methodology, strong consensus was defined as ≥75% agreement and weak consensus as 50%-74% agreement. RESULTS: A total of 94, 91 and 65 collaborators participated in the first, second and third rounds, respectively. We achieved strong consensus for 38 names and 33 anatomical descriptions, and weak consensus for five anatomical descriptions. We agreed on a template for naming peripheral nerve blocks based on the name of the nerve and the anatomical location of the blockade and identified several areas for future research. CONCLUSIONS: We achieved consensus on nomenclature and anatomical descriptions of regional anesthetic techniques for upper and lower limb nerve blocks, and recommend using this framework in clinical and academic practice. This should improve research, teaching and learning of regional anesthesia to eventually improve patient care.
RESUMO
Ankylosing spondylitis is a challenging disease for anesthesiologist due its airway and axial skeleton involvement. A 55 years old male patient suffering from severe ankylosing spondylitis, admitted to Anesthesiology Clinic. He was planned to receive a midline open ventral hernia repair. We decided to perform bilateral ultrasound-guided erector spinae plane (ESP) block at the level of T8 with 0.4 mcg kg-1 hour-1 dexmedetomidine sedation for complete anesthesia of the surgery. We performed ESP block with 25 mL of 0.25% bupivacaine and repeated the same procedure at the contralateral side. Twenty minutes later, the skin incision was started. We didn't need to apply an additive anesthetic or analgesic drug throughout the surgery. ESP block provides analgesia for different dermatomes by effecting ventral rami and rami communicantes of spinal nerves depending on the level of injection site. When performed between T7-T9 levels, it has been reported to effectively attenuate postoperative pain after different types of surgeries.

Rhomboid intercostal block (RIB) is a novel plane block, which is thought to provide analgesia for both the anterior and the posterior hemithorax. Herein, we represent the successful usage of ultrasound-guided RIB on an infant patient to provide analgesia for multiple rib fractures and insertion of a chest tube. A 10-month-old, 8 kg, male infant was scheduled for insertion of a chest tube. The patient had right sided pneumothorax and multiple rib fractures from T4 to T8 after a car crush. Following induction of anaesthesia, he was placed in lateral decubitis position and RIB was performed with 8mL 0.125% bupivacaine. A paediatric epidural catheter was placed into the interfacial plane for post-operative intermittent local anaesthetic injection as a part of multimodal analgesia with administration of intravenous paracetamol 60 mg. The postoperative pain assessment was conducted with FLACC scale at the post-operative 10th minute, 30th minute, 1st, 2nd, 6th, 12th and 24th hours, and the Face, Legs, Activity, Cry, Consolability scale score was 2 at all time-points. Ultrasound-guided RIB provided effective analgesia for insertion of a chest tube and attenuation of pain due to multiple rib-fractures in our infant patient.
RESUMO
BACKGROUND: There is heterogeneity in the names and anatomical descriptions of regional anesthetic techniques. This may have adverse consequences on education, research, and implementation into clinical practice. We aimed to produce standardized nomenclature for abdominal wall, paraspinal, and chest wall regional anesthetic techniques. METHODS: We conducted an international consensus study involving experts using a three-round Delphi method to produce a list of names and corresponding descriptions of anatomical targets. After long-list formulation by a Steering Committee, the first and second rounds involved anonymous electronic voting and commenting, with the third round involving a virtual round table discussion aiming to achieve consensus on items that had yet to achieve it. Novel names were presented where required for anatomical clarity and harmonization. Strong consensus was defined as ≥75% agreement and weak consensus as 50% to 74% agreement. RESULTS: Sixty expert Collaborators participated in this study. After three rounds and clarification, harmonization, and introduction of novel nomenclature, strong consensus was achieved for the names of 16 block names and weak consensus for four names. For anatomical descriptions, strong consensus was achieved for 19 blocks and weak consensus was achieved for one approach. Several areas requiring further research were identified. CONCLUSIONS: Harmonization and standardization of nomenclature may improve education, research, and ultimately patient care. We present the first international consensus on nomenclature and anatomical descriptions of blocks of the abdominal wall, chest wall, and paraspinal blocks. We recommend using the consensus results in academic and clinical practice.

BACKGROUND AND OBJECTIVES: Mastectomy has many potential sources of pain. Rhomboid intercostal block (RIB) is a recently described plane block. The primary hypothesis of the study is that ultrasound-guided RIB combined with general anesthesia would accelerate global quality of recovery scores of patients following mastectomy surgery. Secondary hypothesis is that RIB would reduce postoperative opioid consumption, pain scores, and the need for rescue analgesia. METHODS: Patients aged between 18 and 70 years, with American Society of Anesthesiologists physical status I-II and scheduled for an elective unilateral modified radical mastectomy surgery with axillary lymph node dissection were enrolled to the study. Following endotracheal intubation, patients were randomly allocated into two groups. Patients in the first group (group R) received ultrasound-guided RIB with 30 mL 0.25% bupivacaine. In the control group (group C), no block intervention was applied. All patients received intravenous dexamethasone 8 mg, dexketoprofen trometamol 50 mg intraoperatively and tramadol 1 mg/kg 30 min before the end of surgery for postoperative analgesia. All patients received intravenous morphine patient-controlled analgesia device at the arrival to the recovery room. RESULTS: The descriptive variables of the patients were comparable between group R and group C. Mean quality of recovery-40 score at 24 hours was 164.8±3.9 in group R and 153.5±5.2 in group C (mean difference 11.4 (95% CI 8.8 to 13.9; p<0.001). At 24th hour, median morphine consumption was 5 mg (IQR 4-7 mg) in group R and 10 mg (IQR 8-13 mg) in group C, p<0.001. Intraoperative fentanyl administration, pain scores and the need for rescue postoperative analgesia was similar between groups. CONCLUSIONS: In the current study, ultrasound-guided RIB promoted enhanced recovery and decreased opioid consumption after mastectomy surgery. TRIAL REGISTRATION NUMBER: ACTRN12619000879167.

BACKGROUND: This study aims to evaluate the effects of the anesthesia technique on the intraoperative blood loss in acetabular fracture patients undergoing the Modified Stoppa approach. METHODS: We retrospectively identified 63 patients who underwent a Modified Stoppa approach for acetabular fracture from January 2014 to July 2018. A total of 20 patients were excluded from this study for the following reasons: bilateral acetabular fractures (n=6), undergoing antiaggregant treatment (n=3), incomplete anesthesia records (n=3), emergency pelvic surgery due to hemodynamic instability (n=5), splenic rupture (n=2), and liver laceration (n=1). The patients were divided into two groups as follows: patients undergoing general anesthesia (GA) (n=22) and patients undergoing combined epidural-general anesthesia (CEGA) (n=21). The main outcome measurements studied were the intraoperative blood loss and the need for intraoperative and/or postoperative blood transfusions. RESULTS: No statistically significant differences were found between the groups concerning the age, gender, type of fracture, mechanism of injury, time from injury to surgery, Injury Severity Score, associated injuries, and comorbidities (p>0.05). The mean intraoperative blood losses were 717.27 ml (300-1.600 ml) in the GA group and 473.81 ml (150-1.020 ml) in the CEGA group (p<0.001). In the cases with only an isolated acetabular fracture, the intraoperative blood transfusion means were 2.43 units (1-5 units) in 14 patients in the GA group and 1.27 units (1-4 units) in 15 patients in the CEGA group (p<0.001). CONCLUSION: Less intraoperative bleeding was seen in those patients undergoing CEGA when compared to those undergoing GA. This is a significant advantage for acetabular surgery, which has a long learning curve and a high risk of bleeding.

BACKGROUND: Hip fracture is a common clinical problem which causes severe pain in geriatric patients. However, severe pain following fracture may bring on mental disorders and delirium. A neuroinflammatory response with IL-6 and IL-8 has been shown to be associated with the pathophysiology of delirium. In this study, our primary hypothesis is that preoperative femoral nerve block (FNB) intervention in geriatric patients will more effectively attenuate pain following trochanteric femur fracture than the preoperative paracetamol application. Our secondary hypothesis is that interleukin levels (IL-6, IL-8) in cerebrospinal fluid (CSF) will be lower in the femoral nerve block group than the paracetamol group. Our tertiary hypothesis is that the incidence of postoperative delirium will be lower in the femoral nerve block group. METHODS: The patients over 65 years of age with ASA status II-IV and admitted to the Emergency Service for femur fracture were included in this study. Recommendations of the 'delirium prevention table' were applied to all of the patients at arrival. In the first group, 15 mg/kg paracetamol was administered intravenously every eight hours. In the second group, femoral nerve blockage was performed, and a catheter was placed. Then, 0.5 mL/kg bupivacaine 0.25% was applied every eight hours. In both groups, pain scores four hours after interventions were recorded. All patients were operated within 48 hours under spinal anesthesia. During spinal anesthesia, 2 mL of CSF samples were taken from all patients for analysis of IL-6 and IL-8 cytokines, and pain scores during positioning were recorded. RESULTS: VAS scores four hours after the first preoperative pain treatment and during the positioning for regional anesthesia were significantly lower in the femoral nerve block group. IL-8 levels are significantly lower in the femoral nerve block group but not in IL-6 levels. The incidence of delirium was less in the femoral nerve block group, but the difference was not statistically significant. CONCLUSION: The femoral nerve block was more effective in preoperative pain management of trochanteric femur fracture and preventing pain during regional anesthesia application. The mean IL-8 level was lower in the femoral nerve block group when compared to the paracetamol group. There is no difference in the postoperative delirium incidence between groups.
