Introduction. Retinoblastoma (RB) is a malignant tumor of the embryonic nerve retina. Purpose. To determine the effectiveness of retrobulbar blockade (RbB) with ropivacaine 0.5% for intra- and postoperative analgesia, as well as for the prevention of oculocardial reflex (OCR), postoperative nausea and vomiting (PONV) during enucleation. Material and methods. A prospective, randomized, controlled clinical trial was performed. Eighty patients aged 0 to 10 years were included, who were randomly assigned to the RbB group (retrobulbar blockade with ropivacaine 0.5% with general anesthesia) N = 40 and the GA control group (general anesthesia) N = 40. Results. There were no complications in the RbB group caused by the methodology. In the intraoperative period, the average dose of fentanyl in the RbB group was 4.7 ± 0.7 μg / kg, which is significantly lower than in the OA group of 10.1 ± 1.9 μg / kg (P <0.05). OCR in the RbB group was observed in 5% of cases versus 100% in the GA group (P = 0.002). The average VAS score was 1.8 vs. 3.7 60 minutes after surgery (P <0.001). For the first time 12 hours after surgery, PONV was not observed in the RBB group, and in the control group it was observed in 45% of patients. Conclusions. The study revealed that intraoperative retrobulbar blockade with 0.5% ropivacaine solution in children with RB is effective and safe. Provides stable intraoperative hemodynamics and reduces the need for opioids. Promotes the prevention of OCD and PONV, as well as the improvement of postoperative analgesia during the operation of enucleation of the eyeball in pediatric. Key words: ropivacaine, retrobulbar block, oculocardial reflex, pain, retinoblastoma, enucleation, pediatric patients.

Postoperative nausea and vomiting are common adverse effects of anaesthesia and surgery. Up to 80% of patients may be affected. These outcomes are a major cause of patient dissatisfaction. In addition, postoperative nausea and vomiting can independently cause the occurrence of rather serious complications of the postoperative period, such as aspiration of gastric contents into the airways, hemodynamic disorders in patients with a compromised cardiovascular system, failure of surgical sutures, bleeding, dehydration and electrolyte imbalance which ultimately can lead to disability of patients, prolongation of their hospitalization and higher treatment costs. Material and methods. The paper presents the results of our own research on the use of multimodal low-opioid general anesthesia as one of the methods for the prevention of postoperative nausea and vomiting during anesthetic provision of laparoscopic kidney surgery. The study involved 38 patients who underwent laparoscopic kidney surgery. Results and discussion. To compare the incidence of postoperative nausea and vomiting, patients were randomly divided into two groups. Group 1 used multimodal general anesthesia with standard opioid doses, while group 2 used multimodal low-opioid general anesthesia. The total average dose of fentanyl that was used during the entire time of anesthesia in the control group was 373.3 ± 50.8 μg (4.34 μg / kg / h). The total average dose of fentanyl that was used during the entire time of anesthesia in the study group was 217.39 ± 49.1 μg (1.76 μg / kg / h). In group 1, vomiting occurred in 4 patients out of 15 in the postoperative period, in group 2 there were 4 patients with vomitting, but out of 23 operated patients. The standardized rate of postoperative nausea and vomiting in the control group was 26.6%, in the main group it was 17.3%. Conclusion. As a result of comparing the incidence of postoperative nausea and vomiting in patients of both study groups, we found that a decrease in the dose of perioperative use of opioids helps to reduce the incidence of this complication, which increased the safety of anesthetic management, greatly facilitated and accelerated the rehabilitation of patients after laparoscopic kidney surgery. The work also highlighted and systematized information on the morphology of structures involved in the formation of postoperative nausea and vomiting, on the physiology of this process

BackgroundThe sensory innervation of the lower jaw mainly depends on the third root of the trigeminal nerve, the mandibular nerve (V3). The aim of this single-center, prospective, randomized, double-blind, placebo-controlled study was to evaluate the effectiveness of bilateral V3 block for postoperative analgesia management in mandibular osteotomies.Methods107 patients undergoing mandibular surgery (75 scheduled osteotomies and 32 mandible fractures) were randomized in two groups. A bilateral V3 block was performed in each group, either with ropivacaine 0.75% (block group, n=50) or with a placebo (placebo group, n=57). A postoperative multimodal analgesia was equally provided to both groups. The primary outcome was the cumulative morphine consumption at 24 hours. Secondary outcomes were the occurrence of severe pain and the incidence of postoperative nausea and vomiting (PONV) in the first 24 hours. Data were analyzed on an intention-to-treat basis.ResultsThe cumulative morphine consumption at 24 hours was significantly lower in the block group (median 8.0 mg (IQR 2.0–21.3) vs 12.0 mg (IQR 8.0–22.0), p=0.03), as well as the incidence of severe pain during the 24 hours of follow-up (4.0% vs 22.8%, p<0.01). The mandibular block had no impact on the incidence of PONV.ConclusionBilateral V3 block for mandibular osteotomies is an effective opioid-sparing procedure. It provided better postoperative analgesia in the first 24 hours, and it did not affect PONV incidence.Trial registration numberNCT02618993.

Bispectral index parameter is used to guide the titration of general anesthesia. This monitoring improves recovery times and hospital discharges, as well as minimizes adverse events. The objective of this study is the comparison of anesthesia depth monitoring by conventional and bispectral index on nausea and vomiting after urological surgery. 180 participants who were scheduled for abdominal urological surgery were studied. Patients before induction of anesthesia were randomize into two groups with and without bispectral index monitoring. Incidence and severity of nausea and vomiting were recorded every 30 minutes for 2 hours and every 6 hours to 24 hours after surgery. The incidence of postoperative nausea and vomiting in Bispectral index group is 14.4% and 8.9% and in control group 28.9% and 23.3%, respectively. The risk of nausea and vomiting after surgery was reduced by 14.5% and 14.4%, respectively in patients monitored with bispectral index.INTRODUCTIONNausea is the conscious perception of medulla stimulation that is associated with vomiting center and create vomiting response (1). General anesthesia with the use of inhalants can cause nausea and vomiting after surgery (Postoperative nausea and vomiting, PONV). The incidence of PONV is reported about 20-30 percent (2). It seems that multiple-factor can cause PONV and few items such as anesthetic drugs, kind of surgery and personal risk factors is effective on PONV. These factors make into two categories that includes factors out of control by anesthesiologists and factors can control by anesthesiologists.1. Factors out of control by anesthesiologists: some of these factors are age, gender, past history of PONV and motion sickness, smoking, kind of surgery, operating time and anesthesia time, anxiety of patients and parents. 2. Factors controlled by anesthesiologists: these factors are associated of anesthesia settings, including premedications, kind of anesthesia, anesthesia drugs during surPublishedby Australian

We performed this study to examine the effect of electro-acupuncture (EA) on postoperative pain, postoperative nausea and vomiting (PONV) and recovery in patients after a supratentorial tumor resection. Eighty-eight patients requiring a supratentorial tumor resection were anesthetized with sevoflurane and randomly allocated to a no treatment group (Group C) or an EA group (Group A). After anesthesia induction, the patients in Group A received EA at LI4 and SJ5, at BL63 and LR3 and at ST36 and GB40 on the same side as the craniotomy. The stimulation was continued until the end of the operation. Patient-controlled intravenous analgesia (PCIA) was used for the postoperative analgesia. The postoperative pain scores, PONV, the degree of dizziness and appetite were recorded. In the first 6 hours after the operation, the mean total bolus, the effective times of PCIA bolus administrations and the VAS scores were much lower in the EA group (p < 0.05). In the EA group, the incidence of PONV and degree of dizziness and feeling of fullness in the head within the first 24 hours after the operation was much lower than in the control group (p < 0.05). In the EA group, more patients had a better appetite than did the patients in group C (51.2% vs. 27.5%) (p < 0.05). The use of EA in neurosurgery patients improves the quality of postoperative analgesia, promotes appetite recovery and decreases some uncomfortable sensations, such as dizziness and feeling of fullness in the head.

Background. The problem of postoperative nausea and vomiting has attracted the attention of specialists in various fields of surgery and anesthesiology for a long time and has not lost its relevance today, being the subject of active discussion in domestic and foreign literature. It can become an independent cause of other quite serious postoperative complications. The article presents the results of our own study of the use of multimodal low-opioid general anesthesia as one of the methods for the prevention of postoperative nausea and vomiting during anesthetic provision of laparoscopic kidney surgery. Materials and methods. The study involved 50 patients who underwent laparoscopic kidney surgery. To compare the incidence of postoperative nausea and vomiting, patients were randomly divided into three groups. Group 1 (control group) used multimodal general anesthesia with standard doses of opioids; group 2 used multimodal low-opioid general anesthesia with lidocaine, and group 3 used multimodal low-opioid anesthesia with dexmedetomidine. Results. The total average dose of fentanyl used during the entire time of anesthesia in the control group was 373.3 ± 50.8 μg (4.34 μg/kg/h). The total average dose of fentanyl used during the entire time of anesthesia in group 2 was 217.39 ± ± 49.1 μg (1.76 μg/kg/h). The total average dose of fentanyl used during the entire time of anesthesia in group 3 was 308.33 ± ± 51.49 µg (2.44 µg/kg/h). In group 1, vomiting in the postoperative period occurred in 4 patients out of 15 (26.7 % of cases), in group 2 — in 4 patients out of 23 operated (17.4 % of cases), in group 3 — in 1 patient out of 12 (8.3 % of cases). Conclusions. As a result of comparing the incidence of postoperative nausea and vomiting in the patients of the studied groups, it was found that a decrease in the dose of perioperative use of opioids helps to reduce the incidence of this complication, increases the safety of anesthesia, significantly facilitates and accelerates the rehabilitation of patients after laparoscopic surgery on the kidneys.

Background: Avoiding excessive doses of anesthesia was fundamental, mainly to reduce the adverse effect of anesthesia. Electroencephalography (EEG)-based monitors can be used to measure the depth level of anesthesia and guide intraoperative hypnosis drug and opioid administration. This study aims to evaluate the benefit of using CONOX monitor when administering anesthesia drugs in laparotomy procedures. Method: Twenty patients aged 18-65 years with physical status ASA I-III who underwent major laparotomy surgery with general anesthesia total intravenous anesthesia (TIVA) were divided into two groups. Group A received general anesthesia guided with the CONOX monitor, while group B using standard clinical care. We later evaluate the total use of propofol and fentanyl, intraoperative hemodynamic profile, postoperative cognitive disorder (POCD), intraoperative awareness, postoperative nausea and vomiting (PONV), and moderate to severe pain in the post-anesthesia care unit (PACU). Results: The mean total propofol used is lower in CONOX group (63.6 ± 11.7 mcg/kg/min vs. 74 ± 17.87 mcg/kg/min). A similar result was obtained with fentanyl. The CONOX group use a lower total of fentanyl (212.5 ± 32.3 mcg vs. 249 ± 54.6 mcg) than the control group. POCD was found to be more prevalent in the control group (5 vs 2 patients). While there is no report of intraoperative awareness. Conclusion: The incidence of PONV and moderate to severe pain in PACU was similar between the two groups. This pilot study is a preliminary study to evaluate the benefit of using EEG-based monitors to adjust anesthesia drugs.

BACKGROUND: The retrobulbar block in children is used to enucleate analgesia in the intra- and postoperative period and prevent oculocardiac reflex (OCD), postoperative nausea, and vomiting. However, when the block is performed blindly, it results in serious complications. AIM: This study aimed to evaluate the efficacy and safety of a retrobulbar block performed under ultrasound guidance compared with a retrobulbar block performed blindly during enucleation of the eyeball in children with retinoblastoma. MATERIALS AND METHODS: A prospective randomized controlled trial was performed. The study included 40 patients who met the inclusion criteria. The patients were divided into two groups: 20 patients who underwent ultrasound-guided retrobulbar blockade (RBВ + ultrasound) and 20 patients who underwent blindly retrobulbar blockade (RBВ). RESULTS: There was an insignificant decrease in intraoperative opioid requirements in the RBB + ultrasound group, where the average dose of fentanyl was 41.4 g/kg, and in the RBB group, 4.70.8 g/kg (p 0.05). The time before the administration of the first dose of analgesic in the postoperative period was 4.70.8 h in the RBB group and 11.73.3 h in the RBB + ultrasound group (p 0.05). VAS and CHIPPS scores obtained 6 h after the end of surgery in the RBB + ultrasound and RBB groups were 1.8 (1.2; 2) and 2.5 (3.8; 4.5) points (p 0.05), respectively. CONCLUSION: There was no statistically significant difference between the time of the retrobulbar blockade under ultrasound guidance and the retrobulbar regional block performed blindly. Retrobulbar blockade performed under ultrasound guidance provides a decrease in intraoperative opioid requirements, stable intraoperative hemodynamics, and longer postoperative analgesia.

Objective: Study the efficacy of adding dexamethasone to caudal bupivacaine on postoperative analgesia and vomiting. Study Design: Prospective, randomized double blind controlled clinical trial. Setting: Assiut University Hospital. Patients: Ninety children ASA I-II, undergoing lower orthopedic surgeries. Methods: Patients were randomly allocated into 3 equal groups. All received caudal block after induction of anesthesia with 0.5 mL/kg of 0.25% bupivacaine in addition to 5 mL intravenous (IV) normal saline in the control group, IV 0.5 mg/kg dexamethasone in IV dexamethasone group and lastly 0.1 mg/kg dexamethasone in the caudal dexamethasone group. Postoperative pain scores and rescue analgesic consumption were recorded. Blood glucose, postoperative vomiting, and other side effects were evaluated up to 24 hours after extubation. Results: The time of first analgesia and the number of patients requiring rescue analgesics were significantly decreased with intravenous or caudal dexamethasone. No significant increase in postoperative blood glucose levels were observed. A significant increase in β- Endorphin level at 3 and 24 hours postoperative was found in both dexamethasone groups when compared with the preoperative baseline value. The incidence of postoperative vomiting was significantly decreased in both dexamethasone groups in comparison with the control group. No other side effects were detected. Limitations: Measurement of serum cortisol. Conclusion: Analgesic and antiemetic effects of dexamethasone as an adjunct to caudal block with bupivacaine (0.25%) 0.5 mL/kg is similar whether administered intravenously 0.5 mg/kg or caudally 0.1 mg/kg.

Background: Postoperative Nausea and Vomiting (PONV) is a common complication following dental treatment under general anesthesia (DGA) that may lead to unplanned hospitalization, increased costs and dissatisfaction of parents. Aim: To investigate the incidence of Postoperative Vomiting (POV) on children who underwent dental rehabilitation under general anesthesia and to compare possible preventive effect of Dexamethasone and Ondansetron on occurrences of POV. Study design: A double blind randomized parallel clinical trial was carried out on 352 ASA I children who underwent DGA in a private Saudi hospital in Jeddah. Children were allocated randomly to four groups. Group D of 91 children, received Dexamethasone PONV prophylaxis, group O of 87 children received Ondansetron, group DO of 93 children received combination of the two drugs and group C the control group of 81 children. The three groups were investigated by blinded dental staff for POV episodes, number of times analgesia was needed and post anesthesia care unit time (PACUT). Results: There was a no significant difference between the two drugs on POV. There was a significant difference in POV between control group and groups D, O, and DO. There was significant reduction in need for analgesia in the Dexamethasone groups. The three groups, which had PONV prophylaxis, showed significant reduction in PACUT compared to control group. Conclusions: Antiemetic drugs are useful adjuncts in DGA. Some dental procedures may have higher emetic potential than others. The type of dental procedures done is to be considered when deciding the drug profile in children undergoing DGA.

Background: Simultaneous application of pectoral nerve block and serratus-intercostal plane block (SPB) is one of the most desirable multimodal analgesic strategies, with wide implementation of the enhanced recovery after surgery pathway for modified radical mastectomy (MRM). Objectives: The aim of the present study was to investigate the efficacy and safety of ultrasoundguided pectoral nerve block I (PECS I) and SPB for postoperative analgesia following MRM. Study Design: A randomized, prospective study. Setting: An academic medical center. Methods: A total of 61 women undergoing MRM were randomly divided into 2 groups. The control group (group C, n = 32) received general anesthesia only, whereas the PECS I + SPB treated group (group PS, n = 29) received a combination of pectoral nerve block and SPB in addition to general anesthesia. Results: Pain scores on a visual analog scale, opioid consumption, the duration at the postanesthesia care unit, and the incidence of adverse events were lower in group PS, compared with that of the group C. Moreover, PECS I together with SPB contributed to better sleep quality and higher patient satisfaction of pain relief. Limitations: This study was limited by its sample size. Conclusions: These results suggest that the combination of PECS I and SPB provide superior perioperative pain relief in breast cancer surgery. Key words: Pectoral nerve block, serratus-intercostal plane block, postoperative analgesia, modified radical mastectomy
