RESUMO
Introduction: The inflammatory response after laparoscopy and laparotomy has been compared in studies in adults, but only a few studies have compared the immune response between laparoscopy and laparotomy in children. Aim: To compare open and laparoscopic appendectomies regarding a new biomarker, suPAR, to evaluate the inflammatory response. Material and methods: Patients between 3 and 17 years of age who were admitted to the pediatric surgery department and scheduled for appendectomy due to appendicitis were enrolled in the investigation. The patients were randomized to receive either laparoscopic (n = 20) or conventional open appendectomy (n = 20). The primary outcome was a change in preoperative and postoperative suPAR levels. The secondary outcomes were the white blood cell count, lymphocytes, neutrophils, platelets, C-reactive protein level, appendix diameter, symptoms, symptom duration, surgical complications, operative time, rescue analgesics, hospital stay, and family satisfaction. Results: The mean age of the patients undergoing laparoscopic appendectomy was 10.55 ±2.743 (3-17) years. The mean age of the patients undergoing open appendectomy was 11.40 ±3.515 (3-17) years. A statistically significant difference was found when the postoperative suPAR values between the two groups were compared (p = 0.048). The operative time and hospital stay in the laparoscopic group were significantly shorter than those in the open group (p = 0.001, p = 0.047). Conclusions: Laparoscopic appendectomy is associated with a shorter operative time, a shorter hospital stay, and a smaller inflammatory response caused by surgical stress than open appendectomy. suPAR is an effective marker for comparing postoperative inflammatory stress between open and closed appendectomies.
RESUMO
BACKGROUND: Current knowledge on the ideal local anesthetic concentration for the ultrasound-guided transversus abdominis plane block (TAPB) in pediatrics is scarce. The purpose of this study is to compare the efficacy of US-guided TAPB at two different concentrations of bupivacaine in pediatrics undergoing unilateral inguinal hernia repair. METHODS: After random allocation, 74 children aged 1-8 were randomized to receive US-guided TAPB by using 1 mg.kg- 1 bupivacaine as either 0,25% (0,4 ml.kg- 1) (Group 1) or 0,125% (0,8 ml.kg- 1) (Group 2) concentration. All blocks were performed under general anesthesia, immediately after the induction, unilaterally with a lateral approach. All subjects received intravenous 15 mg/kg paracetamol 0.15 mg/kg dexamethasone and 0.1 mg/kg ondansetron intraoperatively. The primary outcome was the efficacy which is assessed by postoperative FLACC behavioral pain assessment score at 15', 30', 45', 1 h, 2 h, 6 h, and 24 h. The secondary outcomes were to assess the total dose of rescue analgesic consumption, length of hospital stay, the incidence of side effects, complications and satisfaction levels of the patients' parents and the surgeons. RESULTS: Sixty-four children were recruited for the study. Postoperative pain scores were equal between the two groups. There was no need for a rescue analgesic in any group after the postoperative 6thhour. No local or systemic complication or side effect related to anesthesia or surgery was reported. CONCLUSION: TAPB using 1 mg.kg- 1 bupivacaine administered as either high volume/low concentration or low volume/high concentration was providing both adequate analgesia and no side effects. TRIAL REGISTRATION: This trial was retrospectively registered at Clinicaltrals.gov , NCT04202367 .

Quadratus lumborum block (QLB) is a new fascial plane block that may be helpful for laparoscopic surgeries. In this present study, we aim to evaluate the analgesic efficacy of QLB in laparoscopic living related donor nephrectomy (LLRDN) applied continuously via a catheter that was placed under laparoscopic vision by the surgeon. Following the approval of the Clinical Research Ethics Committee of Istanbul University, Istanbul Medical Faculty (2019/1552), 9 study (Group QLB) and 26 control (Group M) patients that underwent LLRDN were enrolled in this retrospective study. All donors underwent left nephrectomy via transperitoneal laparoscopic approach. An epidural catheter was placed between the QL and psoas major (PM) fascial plane intraoperatively by the surgeon under laparoscopic direct vision, and bupivacaine 0.25% 20 mL was injected through the catheter. After the operation, for group QLB, we used a continuous infusion of bupivacaine 0.1% 7 mL/h over 24 hours. Group M patients received intravenous morphine patient controlled analgesia for 24 hours, postoperatively. Pain scores, total morphine consumption, and complications during the first 24 hours after surgery were recorded. During the first postoperative 24 hours, morphine requirement decreased by more than 70% in Group QLB (Group QLB: 5.11 ± 1.16 mg vs Group M: 16.8 ± 7.1 mg) (P < .0001). Postoperative Numeric Rating Scale (NRS) values at the 45th minute and first hour were both significantly lower in Group QLB than Group M (P < .01). This preliminary report showed that QL catheter placement technique provides good postoperative analgesia in patients undergoing LLRDN. However, further randomized controlled studies with extended patient numbers are required to test the efficacy of the technic.

OBJECTIVE: Optimal analgesia following ambulatory surgery is an important matter in patient satisfaction, and it reduces unnecessary hospital admissions. This study investigated whether a caudal block with bupivacaine alone or in a combination with lidocaine can alter postoperative pain scores, complications, and peroperative and postoperative analgesic consumption. MATERIAL AND METHODS: This is a retrospective study that included children who underwent elective circumcision surgery under general anesthesia and caudal analgesia between January and June 2018. Among the 103 children, 17 cases were not analyzed due to an unsuccessful caudal block and procedures simultaneously underwent another operation unrelated to circumcision. We divided the study participants into two groups according to the type of local anesthetic applied: 0.5 mL/kg 0.25% bupivacaine (Group B) and 0.5 mL/kg 0.25% bupivacaine + 3 mg/kg 1% lidocaine (Group BL) caudally. RESULTS: Pain scores were similar between these groups and remained in the mild-to-moderate range throughout the hospitalization (p>0.05). There were significant differences regarding the rescue analgesic use, first micturition, and mobilization times (p<0.001). In addition, we applied the multivariable logistic regression for fentanyl consumption adjusted for first mobilization and micturition time, unlike mobilization, a significantly increased risk for postoperative delayed micturition (OR, 1.06; 95% CI, 1.0-1.12; p=0.038) was found with intra-operative intravenous fentanyl use. CONCLUSION: Our results suggest that the caudal block with a lidocaine+bupivacaine combination decreases rescue analgesic consumption at day-case surgery. In circumcision procedures, the caudal block is an effective and safe analgesic method for intraoperative and postoperative pain control with no side effects. This trial was registered at Clinicaltrals.gov, NCT03911648.
RESUMO
OBJECTIVE: Surgical stress combined with general anaesthesia (GA) suppresses the immune system and leads to cancer cell growth and premature metastasis in major oncological interventions. Epidural analgesia decreases the need for inhalation agents and opioids during surgery by suppressing sympathetic and neuroendocrine responses in the postoperative period. This study aimed to compare the effects of combined general/epidural anaesthesia (GEA)+patient-controlled epidural analgesia (PCEA) and GA+IV patient-controlled analgesia (PCA) on serum tumour necrosis factor-alpha TNF-α), interleukin-1 beta (IL-1ß) and interferon-gamma (IFN-γ) levels in patients undergoing radical cystectomy. METHODS: Sixty-five patients were enrolled in this prospective study. Patients were randomly enrolled to the GEA group, i.e., combined GEA+ PCEA (0.1% bupivacaine+1 µg mL-1 fentanyl), and the GA group, namely combined GA+IV PCA (0.03 mg mL-1 morphine). To evaluate the cytokine response, blood samples were collected at preoperative, postoperative 1st and 24th hours. RESULTS: There was no statistically significant difference in serum TNF-α, IL-1ß and IFN-γ levels between groups GA and GEA at preoperative and postoperative 1st hour and 24th hour. Total remifentanil consumption was significantly lower and length of hospital stay was significantly shorter in the GEA group than in the GA group (p<0.05). CONCLUSION: There is no difference between two anaesthesia methods in terms of serum cytokine levels; however, combined GEA+PCEA technique appeared to be superior to GA+IV PCA because of lower intraoperative narcotic analgesic consumption and shorter hospital stay.
RESUMO
BACKGROUND: Bipolar and monopolar transurethral resection of prostate (TURP) are both widely used for surgical treatment of benign prostatic hyperplasia. Systemic absorption of irrigation fluids during TURP operations leads to variations in blood chemistry. The aim of this prospective clinical study was to compare two different surgical techniques and the systemic effects of irrigation solutions (5 % mannitol vs. 0.9 % sodium chloride) under standardized anesthesia care. METHODS: Fifty-two patients who were scheduled for elective TURP were enrolled in the study. Patients were divided into two groups; the group M; 5 % mannitol was used for irrigation and the group B; 0.9 % sodium chloride was used for irrigation. Spinal anesthesia was performed to all patients. The patients' demographics, prostate volumes, hemodynamic parameters, volumes of irrigation, and IV fluids were recorded. Serum electrolytes (Na+, K+) and hemoglobin (Hb) were analyzed in blood samples taken before the operation (control), at the 45th min of the operation (1st measurement), and 1 h after the end of the surgery (2nd measurement) and recorded. RESULTS: The Na+ value of group M was significantly lower in both the 1st and 2nd measurements compared with the control value (p < 0.001 and p < 0.001). Na+ values of group M were also significantly lower than group B in both the 1st and 2nd measurements (p < 0.001 and p < 0.001). The change in Na+ levels was found to be statistically significant (p < 0.001) in group M, whereas the intergroup changes were not statistically significant in group B. CONCLUSION: Our results demonstrated that bipolar resection coupled with 0.9 % sodium chloride has minimal effects on serum sodium levels compared with monopolar resection.
