RESUMEN
BACKGROUND: Our aim was to observe the effects of local infiltration analgesia (LIA) or erector spinae plane block (ESPB) methods, which we applied preemptively in patients who were scheduled for surgery with a lumbotomy surgical incision and on intraoperative remifentanil consumption, and to compare the postoperative numerical rating scale (NRS), morphine demand, consumption, and pain degrees. METHODS: Sixty American Society of Anesthesiologists I to III patients aged 18 to 75 years who were due to be operated on with a lumbotomy surgical incision were included in the study. The present study was conducted via prospective, randomized controlled, double-blind trials. After the induction of standard anesthesia, LIA was applied to 30 patients and ESPB was applied to 30 patients preemptively. The dose of remifentanil consumed in the intraoperative period was measured, and the hemodynamic parameters were measured every 5 minutes. Morphine bolus treatment with the postoperative patient-controlled analgesia and rescue analgesia with paracetamol were planned for the patients. Postoperative morphine and additional analgesia consumption, NRS, hemodynamic parameters, and complications were recorded for 48 hours. RESULTS: There was no difference between the groups in terms of demographic and hemodynamic data. The mean consumption of remifentanil was measured as 455â ±â 165.23 µg in the intraoperative ESPB group and 296.67â ±â 110.59 µg in the LIA group, and a statistical difference was observed (Pâ =â .001). In the postoperative follow-ups, the ESPB group drug consumption and NRS score averages were significantly lower at all times (Pâ =â .01; patient-controlled analgesia-morphine, 41.93â ±â 14.47 mg vs 57.23â ±â 15.5 mg and additional analgesic-paracetamol: 2.1â ±â 1.06 vs 4.27â ±â 1.14 g). The mean duration of additional analgesic intake of the groups was 10.6â ±â 8.1 in the LIA group, while it was 19.33â ±â 8.87 in the ESPB group, a significant difference. The patient satisfaction questionnaire was also significantly in favor of ESPB (Pâ =â .05). CONCLUSIONS: In conclusion, it has been shown that the intraoperative LIA method is more effective in terms of remifentanil consumption and in controlling pain in operations performed with a flank incision, but the ESPB method provides longer and more effective pain control in postoperative follow-ups.

OBJECTIVE: Postcircumcision pain in children can cause restlessness, crying and bleeding due to trauma. However, there are various methods to prevent postoperative pain, caudal and penile blocks are in the foreground. The primary objective of this study is to evaluate the effectiveness of CB and PB for the relief of postcircumcision pain. The secondary aim is to evaluate the postoperative additional analgesic requirement and side effects of these blocks. MATERIALS AND METHODS: A total of 148 children between the ages of 2 and 10 who underwent circumcision surgery were randomly assigned to two groups in terms of postoperative analgesia. 1) A group of caudal block (0,5 ml/kg %0.25 levobupivacaine) and 2) A group of penile block (0,3 ml/kg %0,25 levobupivacaine). Premedication and sedoanalgesia were standardized. The pain (FLACC Pain Score), analgesic consumption, motor block (Bromage Scale) and side effects (vomiting, hematoma, urinary retention) were assessed postoperatively for 4 hours. RESULTS: Postoperative FLACC scores were lower for caudale block group in the 1st, 3rd and 4th hours. There was no significant difference in postoperative analgesic consumption between the groups. The most common postoperative side effect was vomiting in both groups. CONCLUSION: Caudal block provided more effective analgesia than penile block in postcircumcision pain control.
RESUMEN
INTRODUCTION: The aim of this study was to investigate the effect of perineural dexamethasone against intraneural bupivacaine. MATERIAL AND METHODS: Rats were divided into 9 groups with 6 animals in each group; Group 1 (Intraneural saline 600 µL-2ndday), Group 2 (Intraneural saline 600 µL-7th day), Group 3 (Intraneural saline 600 µL + perineural dexamethasone 0.5 mg/kg-2nd day), Group 4 (Intraneural saline 600 µL + perineural dexamethasone 0.5 mg/kg-7th day), Group 5 (Intraneural bupivacaine 10 mg/kg-2nd day), Group 6 (Intranueral bupivacaine 10 mg/kg-7th day), Group 7 (Intraneural bupivacaine 10 mg/kg + perineurald exam ethasone 0.5 mg/kg-2nd day), Group 8 (Intraneural bupivacaine 10 mg/kg + perineural dexamethasone 0.5 mg/kg-7th day), Group 9 (Control group). At the end of the application period, histopathological and immunohistochemical examinations were analyzed. RESULTS AND CONCLUSION: It was observed that caspase 3 levels significantly increased in the 5th and 6th groups compared to the 1st and 2nd groups (p < 0.01). However, in the 7th and 8th groups, these levels were similar with 1st and 2nd groups. While a significant decrease in S 100 levels was detected in group 6 (p < 0.05), a significant increase occurred in Group 8 and reached the same levels as Group 2. According to histopathological evaluation, edema, vacuolization and myelin degeneration were significantly increased in groups 5 and 6 (p < 0.05). However, in the 8th group, the mentioned data showed a significant decrease and reached the same levels as group 2. As a result, perineural dexamethasone was found to have protective effects against intraneural bupivacaine induced sciatic nerve damage.

The antioxidant and cardioprotective effects of oleuropein have been reported in several studies; however, its effect on ketamine cardiotoxicity has not been known yet. The aim of this study was to investigate the effects of oleuropein in ketamine-induced cardiotoxicity model in rats. A total of 28 male Wistar Albino rats were included in the study and they were randomly divided into four groups, each having seven rats. Group 1 (control): rats were given 1 mL of DMSO by oral gavage method for 7 days. Group 2 (ketamine): on the seventh day of the study, 60 mg/kg ketamine was administered intraperitoneally. Then, 60 mg/kg ketamine was administered intraperitoneally every 10 min for 3 h. Group 3 (oleuropein): rats were given 200 mg/kg/day oleuropein by oral gavage method for 7 days. Group 4 (oleuropein + ketamine): rats were given 1 × 200 mg/kg oleuropein by oral gavage method for 7 days. Furthermore, 60 mg/kg ketamine was administered intraperitoneally on the seventh day of the experiment. Then, 60 mg/kg ketamine was administered intraperitoneally every 10 min for 3 h. Serum cardiac marker (TnI, CK-MB and CK) levels were measured. Histopathological analysis was performed on a portion of the cardiac tissue. Cardiac tissue oxidative stress and antioxidant markers (MDA, GSH, GSH.Px and CAT), TNF-α, IL-6, NF-κB, COX-2 and Nrf-2 gene expressions, and protein conversion levels of related genes were determined. Data obtained showed that ketamine administration increased MDA (p < 0.001), TNF-α (p < 0.01), IL-6 (p < 0.01), COX-2 (p < 0.001) and NF-κB (p < 0.001) levels, as well as serum TnI (p < 0.001), CK-MB (p < 0.001) and CK (p < 0.01) levels whereas decreased GSH (p < 0.05) and Nrf-2 (p < 0.05) levels, as well as GSH-Px (p < 0.001) and CAT (p < 0.05) enzyme activities. Oleuropein administration was observed to decrease MDA, TNF-α, IL-6, COX-2, NF-κB, TnI, CK-MB and CK levels close to the control group and to increase GSH levels and GSH-Px and CAT enzyme activities close to the control group. This study showed that oleuropein administration reversed the increased oxidative stress and inflammation as a result of the use of ketamine and had protective effects on the heart.
