Eur Arch Otorhinolaryngol 2024; 281:2819-2831. [PMID: 38231242 DOI: 10.1007/s00405-024-08455-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Accepted: 01/02/2024] [Indexed: 01/18/2024]
Abstract
PURPOSE To perform a systematic review and meta-analysis of randomized controlled trials (RCTs) that assessed the efficacy of perioperative intravenous lidocaine versus placebo in improving the quality of surgical field during functional endoscopic sinus surgery (FESS). METHODS PubMed, Scopus, Web of Science, and CENTRAL were thoroughly searched from inception until June 2023. The included RCTs were evaluated via RoB-2 tool. Our primary endpoint included intraoperative surgical field quality, and secondary endpoints involved operative duration, estimated blood loss, time for post-anesthesia care unit (PACU) discharge, postoperative pain, mean difference in heart rate (HR), and mean difference in mean arterial pressure (MAP). Continuous data were pooled as mean difference (MD) or standardized mean difference (SMD) via RevMan software. Also, the certainty of evidence for each outcome were assessed according to the GRADE system. RESULTS Four RCTs with total of 267 patients were included. Regarding the intraoperative quality of surgical field, the results indicated a significant difference in favor of the lidocaine group compared to the placebo group (n = 3 RCTs, MD - 0.80, 95% CI [- 0.98, - 0.61], p < 0.001, moderate certainty of evidence). The trial sequential analysis showed there is a substantial and conclusive evidence. Regarding time for PACU discharge, there was a significant difference that favor lidocaine group (p < 0.05). On the contrary, there was no significant difference between lidocaine and placebo groups in terms of operative duration, estimated blood loss, postoperative pain, mean change in MAP and HR, (p > 0.05). CONCLUSION Our review revealed that lidocaine infusion, compared with a placebo, significantly improved the surgical field and shortened the time required for PACU discharge. However, lidocaine did not reduce surgery time, estimated blood loss, postoperative pain, MAP, or HR.

Su YH, Luo DC, Pang Y. Effects of intraoperative Magnesium sulfate infusion on emergency agitation during general anesthesia in patients undergoing radical mastectomy: a randomized controlled study. BMC Anesthesiol 2023; 23:326. [PMID: 37749511 PMCID: PMC10521581 DOI: 10.1186/s12871-023-02288-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 09/18/2023] [Indexed: 09/27/2023] Open
Abstract
BACKGROUND Emergency agitation is a common postoperative complication in patients under general anesthesia, which can lead to unpredictable damages such as shedding of drainage tube and bleeding from the wound. The purpose of the study is to investigate whether intraoperative infusion of Magnesium Sulfate reduces the incidence of emergency agitation (EA) in patients undergoing radical mastectomy, and to evaluate its safety and efficacy. METHODS A total of 70 patients were randomly assigned to two groups: the Magnesium group (M group) and the control group (C group). After a routine intravenous anesthetic induction, patients in the M group received a 30 mg/kg bolus of intravenous magnesium during the first hour and then a continuous infusion of 10 mg/kg ×h until the end of the surgery, patients in the C group received 0.9% saline at the same volume and rate. The sedation-agitation scale (SAS) and the visual analogue scale were used to assess agitation and pain, respectively. RESULTS Compared to the C group, the M group reduced the incidence of EA significantly (odds ratio 0.26, 95% confidence interval 0.09-0.71, P = 0.009). The postoperative pain score of the magnesium sulfate group(0(0,1)) was lower than that of the control group(2(0,3)) at T0 (P = 0.011). Additionally, the M group required a lower dosage of remifentanil during surgery compared to the C group(300.4 ± 84 versus 559.3 ± 184 µg, respectively, P<0.001). CONCLUSIONS the intraoperative infusion of magnesium sulfate is a safe and effective method for reducing the incidence of emergency agitation in patients undergoing radical mastectomy.

Abstract
Balanced anesthesia relies on the simultaneous administration of different drugs to attain an anesthetic state. The classic triad of anesthesia is a combination of a hypnotic, an analgesic, and a neuromuscular blocker. It is predominantly the analgesic pillar of this triad that became more and more supported by adjuvant therapy. The aim of this approach is to evolve into an opioid-sparing technique to cope with undesirable side effects of the opioids and is fueled by the opioid epidemic. The optimal strategy for balanced general anesthesia in ambulatory surgery must aim for a transition to a multimodal analgesic regimen dealing with acute postoperative pain and ideally reduce the most common adverse effects patients are faced with at home; sore throat, delayed awakening, memory disturbances, headache, nausea and vomiting, and negative behavioral changes. Over the years, this continuum of "multimodal general anesthesia" adopted many drugs with different modes of action. This review focuses on the most recent evidence on the different adjuvants that entered clinical practice and gives an overview of the different mechanisms of action, the potential as opioid-sparing or hypnotic-sparing drugs, and the applicability specifically in ambulatory surgery.

Abstract
Background Emergence delirium is an early postoperative behavior change in pediatric patients, posing risks to patient safety and leading to prolonged hospital stays and increased medical costs. As a result, the research on emergence delirium has grown substantially. This study aims to identify the most influential literature, trends, and topics in emergence delirium research, as well as to quantify the fundamental data of academic publications on this topic. Methods We searched for articles on emergence delirium in the Science Citation Index Expanded databases, covering the period from 2002 to 2022. Bibliographic information, including countries, institutions, journals, authorships, references, and keywords, was collected for further analysis. Results A total of 739 articles on emergence delirium published between 2002 and 2022 were collected. China emerged as the most prolific publisher in this field, accounting for over 30% of all articles (226 publications), followed by the United States (n = 143) and South Korea (n = 92). The top three productive journals were Pediatric anesthesia (n=78, IF=2.129), Anesthesia and Analgesia (n=28, IF=6.627), and BMC Anesthesiology (n=28, IF=2.583). Yonsei University was the most active institution, with 22 publications related to emergence delirium. Among authors, Kin, Hee-Soo (n = 9) published the most articles in this field, followed by Yao, Yusheng (n = 7), Lee, Ji-Hyun (n = 7). The prominent topics in emergence delirium research during the past two decades were "children", "emergence delirium" and "propofol". Conclusion Through bibliometric analysis, this study provides a comprehensive overview of the trends and developments in the field of emergence delirium over the past two decades. The results demonstrate a significant growth in emergence delirium research worldwide, with China leading in the number of publications. Despite the wealth of literature on strategies for preventing and managing emergence delirium in clinical settings, further basic research is needed to elucidate the underlying mechanisms of emergence delirium.

Intramuscular Ketamine Effect on Postnasal Surgery Agitation: A Prospective Double-Blinded Randomized Controlled Trial. Anesthesiol Res Pract 2023; 2023:2286451. [PMID: 36890908 PMCID: PMC9988369 DOI: 10.1155/2023/2286451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Revised: 02/16/2023] [Accepted: 02/17/2023] [Indexed: 03/02/2023] Open
Abstract
This study investigates the effect of intramuscular ketamine on emergence agitation (EA) following septoplasty and open septorhinoplasty (OSRP) when administered at subanesthetic doses at the end of surgery. A random sample of 160 ASA I-II adult patients who underwent septoplasty or OSRP between May and October, 2022, was divided into two groups of eighty patients each: ketamine (Group K) and saline (Group S) with the latter serving as the control group. At the end of surgery immediately after turning off the inhalational agent, Group K was administered with intramuscular 2 ml of normal saline containing 0.7 mg/kg ketamine and Group S with 2 ml of intramuscular normal saline. Sedation and agitation scores at emergence from anesthesia were recorded after extubation using the Richmond Agitation-Sedation Scale (RASS). The incidence of EA was higher in the saline group than in the ketamine group (56.3% vs. 5%; odds ratio (OR): 0.033; 95% confidence interval (CI): 0.010-0.103; p < 0.001). Variables associated with a higher incidence of agitation were ASA II classification (OR: 3.286; 95% (CI): 1.359-7.944; p=0.008), longer duration of surgery (OR: 1.010; 95% CI: 1.001-1.020; p=0.031), and OSRP surgery (OR: 2.157; CI: 1.056-5.999; p=0.037). The study concluded that the administration of intramuscular ketamine at a dose of 0.7 mg/kg at the end of surgery effectively reduced the incidence of EA in septoplasty and OSRP surgery.

Abstract
STUDY OBJECTIVE Emergence agitation (EA) is a common complication in pediatric patients after general anesthesia. The effectiveness of magnesium sulfate in decreasing the incidence of EA in children remains controversial. Therefore, a systematic review and meta-analysis was performed to assess the efficacy of magnesium sulfate in preventing EA in pediatric patients following general anesthesia. DESIGN Systematic review and meta-analysis. SETTING PubMed, Embase, Web of Science, and Cochrane Library were searched to identify eligible randomized controlled trials from their respective database inception dates to June 30, 2021. PATIENTS Pediatric patients (< 18 years old) undergoing general anesthesia. INTERVENTIONS Intravenous administration of magnesium sulfate. MEASUREMENTS The primary outcome of the meta-analysis was EA incidence. The risk of bias of the included studies was evaluated using the revised Cochrane risk of bias tool for randomized trials (RoB 2.0). Grading of Recommendations, Assessment, Development, and Evaluation was applied to assess the level of certainty. MAIN RESULTS Eight studies with 635 participants were identified. The forest plot revealed no significant difference in the incidence of EA between patients treated with magnesium sulfate and the control group (risk ratio = 0.69, 95% confidence interval [0.44, 1.07]; P = 0.10, I2 = 74%, moderate level of certainty). Additionally, magnesium sulfate did not reduce postoperative pediatric anesthesia emergence delirium scores but prolonged the emergence time. No significant differences were observed in postoperative complications (nausea, vomiting, laryngospasm, breath-holding, coughing, oxygen desaturation, and cardiac arrhythmias). CONCLUSIONS Administration of magnesium sulfate during general anesthesia did not affect the occurrence of EA in pediatric patients. However, magnesium sulfate can prolong the emergence time without adverse effects. PROSPERO registration number: CRD42021252924.

Abstract
Introduction and objective Emergence Delirium (ED), particularly in children, is characterized by mental confusion, irritability, disorientation, and inconsolable crying. ED prolongs the time required in the Post-Anesthesia Care Unit (PACU) and increases concern and anxiety in parents. The present study aimed to determine the effectiveness and safety of low-dose clonidine in preventing ED in children receiving sevoflurane anesthesia for tonsillectomy/adenotonsillectomy. Methods A randomized, double-blind clinical trial was conducted between November 2013 and January 2014. Sixty-two children aged 2–12 years, scheduled to undergo tonsillectomy/adenotonsillectomy, and classified as American Society of Anesthesiologists (ASA) physical status I/II were included, with 29 being randomized to receive 1 μg.kg-1 clonidine intravenously, and 33 allocated to a control group that received no clonidine. Anesthesia was induced and maintained with sevoflurane. Children with altered state of consciousness, neurological deficit, history of allergy to dipyrone, or receiving other drugs such as preanesthetic agents were excluded from the study. The primary outcome was the presence of ED in the initial 20 minutes in the PACU according to the Pediatric Anesthesia Emergence Delirium (PAED) scale. The Chi-Square test and Fisher’s two-tailed exact test were used for statistical analysis, as applicable. Significance level was set at 5%, and Risk Ratios (RR) and their 95% Confidence Intervals (95% CI) were calculated. Results The frequency of ED was significantly decreased in the group of children who received clonidine (17.2% vs. 57.6%; RR = 0.30; 95% CI 0.13–0.70; p = 0.001). There was no difference between groups with respect to the frequency of postoperative self-harm (falls and bruises), dislodged catheters, and for most of the other adverse events evaluated. Conclusions The use of 1 μg.kg-1 intravenous clonidine during anesthesia induction can effectively reduce the incidence of ED in children undergoing elective tonsillectomy/adenotonsillectomy under general inhalation anesthesia with sevoflurane.

Abstract
This study investigated whether intraoperative infusion of magnesium sulphate reduces the incidence of emergence agitation (EA) in paediatric patients who undergo ambulatory ophthalmic surgery using the Paediatric Anaesthesia Emergence Delirium (PAED) scale. Ninety-two paediatric patients who were scheduled for elective ophthalmic surgery were randomly allocated to two groups: control or magnesium. In the magnesium group, patients received an initial intravenous loading dose of 30 mg/kg of 10% solution of magnesium sulphate over 10 min and then a continuous infusion of 10 mg/kg×h during the surgery. In the control group, an equal volume of 0.9% isotonic saline was administered in the same way as in the magnesium group. The PAED scale was assessed at 15-min intervals until the PAED score reached below 10 at the postanaesthetic care unit. EA was defined as a PAED score of 10 or higher. Of the 86 patients recruited, 44 and 42 were allocated to the control and magnesium groups, respectively. The incidence of EA was 77.3% in the control group and 57.1% in the magnesium group (odds ratio, 0.392; 95% confidence interval, 0.154 to 0.997; p = 0.046). The intraoperative infusion of magnesium sulphate significantly reduced the incidence of EA.

Abstract
AIM In this study, we aimed to compare the effects of standard verbal information in the preoperative period and the information by visual expression and physical applications in the development of agitation, edema and ecchymosis in the postoperative period. MATERIALS AND METHODS The study was carried out in 60 ASA I-II patients who were going to undergo open rhinoplasty by plastic surgery. In the Preoperative Anesthetic Assessment the patients were divided into two groups as the patients given standard verbal information (Group S; n = 30) and those informed with a catalog which contains visuals (Group V; n = 30) In the preoperative period, anxiety levels of the patients were evaluated. Standard anesthesia induction was performed in both groups after standard monitoring. Patients were monitored in the post-anesthesia care unit and ward. Patient's extubation quality, presence of postoperative agitation and periorbital edema and ecchymosis at the 6th, 12th, 18th, and 24th hours were evaluated. RESULTS No significant difference was found between the groups in terms of intraoperative and postoperative MAP, HR, extubation quality, presence of recovery agitation, postoperative pain, development edema and ecchymosis (P > 0.05). Significant positive correlation was found between post-extubation MAP and edema scores at the 16th and 24th hours postoperatively and between the post-anesthesia care unit entry MAP and ecchymosis at the 24th postoperative hours independently of the groups (r = 0.27; P = 0.038, r = 0.302; P = 0.019, r = 0.345; P = 0.007, respectively). RESULT In our study, it was concluded that detailed visual information and physical application in the preoperative period among rhinoplasty patients had no effect on the incidence of postoperative agitation, development of edema and ecchymosis.

Abstract
Sevoflurane is a widely used inhalational anesthetic in pediatric surgeries, which is considered reasonably safe and reversible upon withdrawal. However, recent preclinical studies suggested that peri-neonatal sevoflurane exposure may cause developmental abnormalities in the brain. The present review aimed to present and discuss the accumulating experimental data regarding the undesirable effects of sevoflurane on brain development as revealed by the laboratory studies. First, we summarized the long-lasting side effects of neonatal sevoflurane exposure on cognitive functions. Subsequently, we presented the structural changes, namely, neuroapoptosis, neurogenesis and synaptogenesis, following sevoflurane exposure in the immature brain. Finally, we also discussed the potential mechanisms underlying subsequent cognitive impairments later in life, which are induced by neonatal sevoflurane exposure and pointed out potential strategies for mitigating sevoflurane-induced long-term cognitive impairments. The type A gamma-amino butyric acid (GABAA) receptor, the main targets of sevoflurane, is excitatory rather than inhibitory in the immature neurons. The excitatory effects of the GABAA receptors have been linked to increased neuroapoptosis, elevated serum corticosterone levels and epigenetic modifications following neonatal sevoflurane exposure in rodents, which might contribute to sevoflurane-induced long-term cognitive abnormalities. We proposed that the excitatory GABAA receptor-mediated HPA axis activity might be a novel mechanism underlying sevoflurane-induced long-term cognitive impairments. More studies are needed to investigate the effectiveness and mechanisms by targeting the excitatory GABAA receptor as a prevention strategy to alleviate cognitive deficits induced by neonatal sevoflurane exposure in future.

Role of T-type Calcium Channels in Generating Hyperexcitatory Behaviors during Emergence from Sevoflurane Anesthesia in Neonatal Rats. Neurosci Bull 2020; 36:519-529.

Abstract
In the current study, we sought to investigate whether T-type Ca2+ channels (TCCs) in the brain are involved in generating post-anesthetic hyperexcitatory behaviors (PAHBs). We found that younger rat pups (postnatal days 9-11) had a higher incidence of PAHBs and higher PAHB scores than older pups (postnatal days 16-18) during emergence from sevoflurane anesthesia. The power spectrum of the theta oscillations (4 Hz-8 Hz) in the prefrontal cortex was significantly enhanced in younger pups when PAHBs occurred, while there were no significant changes in older pups. Both the power of theta oscillations and the level of PAHBs were significantly reduced by the administration of TCC inhibitors. Moreover, the sensitivity of TCCs in the medial dorsal thalamic nucleus to sevoflurane was found to increase with age by investigating the kinetic properties of TCCs in vitro. TCCs were activated by potentiated GABAergic depolarization with a sub-anesthetic dose of sevoflurane (1%). These data suggest that (1) TCCs in the brain contribute to the generation of PAHBs and the concomitant electroencephalographic changes; (2) the stronger inhibitory effect of sevoflurane contributes to the lack of PAHBs in older rats; and (3) the contribution of TCCs to PAHBs is not mediated by a direct effect of sevoflurane on TCCs.

Abstract
BACKGROUND Postoperative agitation is harmful for the patient as it may be associated with removal of catheters, nasal packs, oxygen masks and self-injury, and pose a danger to operating theatre staff. OBJECTIVE The current study investigated the potential role of magnesium sulphate in treatment of postoperative agitation following functional endoscopic sinus surgery. DESIGN A randomised, double-blinded, placebo-controlled trial. SETTING ENT operating room, Menofia University Hospitals, Egypt. PATIENTS A total of 312 adult patients (171 men and 141 women) were enrolled in the study. Eighteen patients (10 men and eight women) were excluded; data from 294 patients were analysed. Inclusion criteria were age between 20 and 60 years, American Society of Anesthesiologists' physical status 1 or 2 scheduled for functional endoscopic sinus surgery. Exclusion criteria were hypertension, cardiac ischaemia, cerebrovascular insufficiency, neuromuscular diseases, pregnancy, prolonged treatment with calcium-channel blockers, diabetic neuropathy or a known allergy to magnesium compounds. INTERVENTIONS Patients were allocated randomly to either the magnesium group (a magnesium infusion of 30 mg kg in the first hour followed by 9 mg kg h until the end of the surgical procedure) or the control group (0.9% saline at the same volume and rate). Hypotensive anaesthesia was induced by nitroglycerine 5 to 20 μg kg min. In the postanaesthetic care unit (PACU), patients were assessed for agitation and pain using the Richmond agitation-sedation scale and numerical rating scale, respectively. PRIMARY OUTCOME The incidence and severity of agitation measured 5 min after admission to the PACU. RESULTS Magnesium reduced postoperative agitation at time 0 (P = 0.009) and 5, 10, 15 and 30 min after PACU admission (P < 0.0001) as well as total agitation score [3 (0 to 6) versus 9 (0 to 12), P < 0.0001]. Magnesium also reduced pain [4.5 (4 to 5) versus 6 (5 to 6.25), P < 0.0001] and length of PACU stay (88 ± 23 versus 111 ± 31 min, P < 0.0001). The magnesium group consumed less pethidine in PACU compared with the control group (43 ± 15 and 59 ± 19 mg, respectively, P < 0.0001). The intraoperative end-tidal CO2 tension was comparable between groups (4.7 ± 0.7 versus 4.8 ± 1.2 kPa). CONCLUSION Intraoperative infusion of magnesium in patients undergoing endoscopic sinus surgery reduced postoperative agitation, pethidine consumption and pain assessed in the PACU. It also decreased the length of stay in PACU compared with the control group. TRIAL REGISTRATION The current study was registered according to WHO and ICMJE standards on 7 January 2014, under registration number PACTR 201402000737691.

Abstract
BACKGROUND Emergence delirium is a common complication of sevoflurane anesthesia in children. AIMS We examined the effects of maintaining remifentanil infusion during the recovery period on the incidence of emergence delirium in preschool-age children undergoing strabismus surgery under sevoflurane anesthesia. METHODS Eighty children (aged 3-7 years) were randomly assigned to either the control group (group C; intraoperative remifentanil infusion) or the intervention group (group R; intraoperative remifentanil infusion followed by remifentanil maintenance during the recovery phase). Intraoperative remifentanil infusion (0.2 μg/kg/min) was discontinued upon surgery completion in the group C, and was maintained until the discharge criteria were met at a dose of 0.05 μg/kg/min in the group R. The incidence of emergence delirium was assessed using a five-point agitation scale and the Pediatric Anesthesia Emergence Delirium scale after arrival in the postanesthesia care unit. Postoperative pain was assessed using the Children's Hospital of Eastern Ontario Pain Scale. RESULTS The incidence of emergence delirium according to the five-point agitation scale (scores ≥ 4) was lower in the group R (33.3%) compared to the group C (68.3%) (odds ratio 0.206; 95% CI 0.080 to 0.531; P = 0.002). Similar results were obtained using the Pediatric Anesthesia Emergence Delirium scale (scores > 12), with an incidence of 5.1% in the group R and 34.0% in the control group (odds ratio 0.104; 95% CI 0.022 to 0.497; P = 0.001). The Children's Hospital of Eastern Ontario Pain Scale scores and occurrence of postoperative adverse events including laryngospasm, desaturation, nausea, and vomiting were similar between the two groups. CONCLUSION Maintaining a low dose of remifentanil (0.05 μg/kg/min) throughout the recovery phase attenuated the incidence of emergence delirium in children undergoing strabismus surgery under sevoflurane anesthesia.

Abstract
Introduction Anesthesia emergence delirium is a self-limiting clinical phenomenon very common in children. Although pathophysiology is still uncertain, some factors seem to be involved, such as rapid awakening in an unknown environment, agitation during anesthetic induction, preoperative anxiety, environmental disorders, use of preanesthetic medication, use of inhalational anesthetics, and postoperative pain. Objective To determine the prevalence and risk factors associated with anesthesia emergence delirium in children undergoing outpatient surgery. Methods A prospective observational study was carried out with 100 children aged 2–10 years, who underwent surgery on an outpatient basis. The study variables were: anesthesia emergence delirium and the associated risk factors (preoperative anxiety, child impulsive behavior, use of pre-anesthetic medication, traumatic induction, type of anesthesia, and postoperative pain). Multivariate Poisson's logistic regression was used to analyze the possible explanatory variables, where the prevalence ratios were estimated with the respective 95% confidence intervals, considering a significance level of 5%. Results Delirium and pain were observed in 27% and 20% of children, respectively. Only postoperative pain after Poisson's regression, was shown to be associated with anesthesia emergence delirium, with a prevalence ratio of 3.91 (p < 0.000). Conclusion The present study showed 27% prevalence of anesthesia emergence delirium in the study population. The incidence of anesthesia emergence delirium was higher in children who had postoperative pain.

Abstract
BACKGROUND In addition to general anaesthetic effects, sevoflurane can also induce hyperactive behaviours during induction and recovery, which may contribute to neurotoxicity; however, the mechanism of such effects is unclear. Volatile anaesthetics including isoflurane have been found to activate the kainate (GluK2) receptor. We developed a novel mouse model and further explored the involvement of kainate (GluK2) receptors in sevoflurane-induced hyperactivity. METHODS Maximal speed, mean speed, total movement distance and resting percentage of C57BL/6 mice were quantitatively measured using behavioural tracking software before and after sevoflurane anaesthesia. Age dependence of this model was also analysed and sevoflurane-induced hyperactivity was evaluated after intracerebral injection of the GluK2 receptor blocker NS-102. Neurones from the hippocampal CA3 region were used to undertake in vitro electrophysiological measurement of kainate currents and miniature excitatory postsynaptic potential (mEPSP). RESULTS Sevoflurane induced significant hyperactivities in mice under sevoflurane 1% anaesthesia and during the recovery period, characterized as increased movement speed and total distance. The hyperactivity was significantly increased in young mice compared with adults (P<0.01) and pre-injection of NS-102 significantly prevented this sevoflurane-induced hyperactivity. In electrophysiological experiments, sevoflurane significantly increased the frequency of mEPSP at low concentrations and evoked kainate currents at high concentrations. CONCLUSIONS We developed a behavioural model in mice that enabled characterization of sevoflurane-induced hyperactivity. The kainate (GluK2) receptor antagonist attenuated these sevoflurane-induced hyperactivities in vivo, suggesting that kainate receptors might be the underlying therapeutic targets for sevoflurane-induced hyperactivities in general anaesthesia.

Abstract
Emergence agitation preventive medicine should be combined with pediatric anesthesia because of the high frequency of emergence agitation. However, it is challenging to determine the most appropriate medication that can be introduced into pediatric anesthesia for the sake of emergence agitation prevention. We reviewed and retrieved the data from PubMed and Embase. Various medications were assessed based on several endpoints including Emergence agitation outcomes (EA), postoperative nausea and vomiting (PONV), the number of patients who required analgesic (RA), pediatric anesthesia emergence delirium (PAED), the extubation time, the emergency time and the duration of post-anesthesia care unit (PACU) stay. Both traditional and network meta-analysis were carried in this study. A total of 45 articles were complied with the selection criteria and the corresponding articles were reviewed. Fentanyl demonstrated the highest cumulative ranking probability which was followed by those of ketamine and dexmedetomidine with respect to EA and PAED. When PONV and RA were concerned together, clonidine exhibited the highest cumulative ranking probability compared to other medications. Our study suggested that dexmedetomidine perhaps is the most appropriate prophylactic treatment which can be introduced into anesthesia for preventing emergence agitation.

Abstract
BACKGROUND The differences in the incidence and severity of emergence agitation (EA) and emergence times between desflurane and sevoflurane anesthesia have not been as clearly elucidated in children as in adults. METHODS The design of the study is a systematic review with meta-analysis of randomized controlled trials. The study methodology is based on the Cochrane Review Methods. A comprehensive literature search was conducted to identify clinical trials comparing the incidence or severity of EA and emergence times in children anesthetized with desflurane or sevoflurane. Two reviewers independently assessed each study according to predefined inclusion criteria and extracted data from each study using a prespecified data extraction form. The data from each study were combined using a fixed effect or random effect model to calculate the pooled risk ratio (RR) or standardized mean difference (SMD) and 95% confidence interval (CI). Funnel plots were used to assess publication bias. Subgroup and sensitivity analyses were performed. RESULTS Fourteen studies met the inclusion criteria. Among the 1196 patients in these 14 studies, 588 received desflurane anesthesia and 608 received sevoflurane anesthesia. The incidence of EA was comparable between the 2 groups (pooled RR = 1.21; 95% CI: 0.96-1.53; I = 26%), and so was the severity of EA (EA score) between the 2 groups (SMD = 0.12; 95% CI: -0.02 to 0.27; I = 0%). Extubation and awakening times were shorter in the desflurane group than in the sevoflurane group; the weighted mean differences were -2.21 (95% CI: -3.62 to -0.81; I = 93%) and -2.74 (95% CI: -3.80 to -1.69; I = 85%), respectively. No publication bias was found in the funnel plot. The subgroup analysis based on the type of EA scale showed a higher incidence of EA in the desflurane group than in the sevoflurane group in studies using 3-, 4-, or 5-point EA scales; the pooled RR was 1.38 (95% CI: 1.10-1.73; I = 37%). CONCLUSION The incidence and severity of EA were comparable between desflurane and sevoflurane anesthesia in children; however, emergence times, including extubation and awakening times, were shorter in desflurane anesthesia.

Abstract
BACKGROUND AND OBJECTIVES The goal of this meta-analysis study was to assess the effects of fentanyl on emergence agitation (EA) under sevoflurane anesthesia in children. SUBJECTS AND METHODS We searched electronic databases (PubMed, Embase, Web of Science and the Cochrane Central Register of Controlled Trials) for articles published until December 2014. Randomized controlled trials (RCTs) that assessed the effects of fentanyl and placebo on EA under sevoflurane anesthesia in children that the outcome were the incidence of EA, postoperative pain, emergence time or adverse effects were included in this meta-analysis. RESULTS A total of 16 studies, including 1362 patients (737 patients for the fentanyl group and 625 for the placebo group), were evaluated in final analysis. We found that administration of fentanyl decreased the incidences of EA (RR = 0.37, 95% CI 0.27~0.49, P<0.00001) and postoperative pain (RR = 0.59, 95% CI 0.41~0.85, P = 0.004) but increased the incidence of postoperative nausea and vomiting (PONV) (RR = 2.23, 95% CI 1.33~3.77, P = 0.003). The extubation time (WMD = 0.71 min, 95% CI 0.12~1.3, P = 0.02), emergence time (WMD = 4.90 min, 95% CI 2.49~7.30, P<0.0001), and time in the postanesthesia care unit (PACU) (WMD = 2.65 min, 95% CI 0.76~4.53, P = 0.006) were slightly increased. There were no significant differences in the time to discharge of day patients (WMD = 3.72 min, 95% CI -2.80~10.24, P = 0.26). CONCLUSION Our meta-analysis suggests that fentanyl decreases the incidence of EA under sevoflurane anesthesia in children and postoperative pain, but has a higher incidence of PONV. Considering the inherent limitations of the included studies, more RCTs with extensive follow-up should be performed to validate our findings in the future.

Abstract
Objective: Emergence agitation (EA), a short-lived, self-limiting phenomenon, arises frequently after the use of inhalational agents and hampers the implementation of pediatric ambulatory surgery in spite of using so many drugs with variable efficacy. Methods: In this prospective, double-blinded, parallel group study (2008–2009), 80 children of both sex aged 3–7 years, with American Society of Anesthesiologists (ASA) physical status grade I-II, undergoing sevoflurane-based general anesthesia for elective day care surgery were randomly assigned into groups C or D. Group C received 4 μg/kg intranasal clonidine, whereas group D received 1 μg/kg intranasal dexmedetomidine, 45 min before induction of anesthesia. In postanesthesia care unit (PACU), the incidence of EA was assessed with Aonos four-point scale and the severity of EA was assessed with pediatric anesthesia emergence delirium scale upon admission (T0), after 5 min (T5), 15 min (T15), and 25 min (T25). Extubation time, emergence time, duration of PACU stay, dose and incidence of fentanyl use for pain control were noted. Findings: Based on comparable demographic profiles, the incidence and severity of EA were significantly lower in group D as compared to group C at T0, T5, T15, and T25. But time of regular breathing, awakening, extubation, and emergence were significantly delayed in group D than C. The number and dose of fentanyl used in group C were significantly higher than group D. PACU and hospital stay were quite comparable between groups. Conclusion: Intranasal dexmedetomidine 1 μg/kg was more effective than clonidine 4 μg/kg in decreasing the incidence and severity of EA, when administered 45 min before the induction of anesthesia with sevoflurane for pediatric day care surgery. Dexmedetomidine also significantly reduced fentanyl consumption in PACU.

Risk factors of emergence agitation in adults undergoing general anesthesia for nasal surgery. Clin Exp Otorhinolaryngol 2015; 8:46-51. [PMID: 25729495 PMCID: PMC4338091 DOI: 10.3342/ceo.2015.8.1.46] [Citation(s) in RCA: 65] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2014] [Revised: 02/09/2014] [Accepted: 02/10/2014] [Indexed: 01/08/2023] Open
Abstract
Objectives To identify the incidence and the risk factors of emergence agitation in adults undergoing general anesthesia for nasal surgery. Methods We retrospectively examined 792 patients aged ≥18 years who underwent general anesthesia for elective nasal surgery between July 2012 and August 2013. Patients in the postanesthesia care unit with a Richmond Agitation Sedation Scale≥+1 at any time were considered to have emergence agitation. Results The overall incidence of emergence agitation is 22.2%. From multivariate regression analysis, the following six variables were found to be significantly associated with emergence agitation (P<0.05): younger age, recent smoking, sevoflurane anesthesia, postoperative pain on the numerical rating scale (NRS)≥5, presence of a tracheal tube, and presence of a urinary catheter. Presence of a tracheal tube was the greatest risk factor, increasing the risk of developing emergence agitation by approximately fivefold (odds ratio, 5.448; 95% confidence interval, 2.973 to 9.982). Younger age was also a strong risk factor (odds ratio, 0.975 for each 1-year increase; 95% confidence interval, 0.964 to 0.987). Current smoking, sevoflurane anesthesia, postoperative pain of NRS≥5, and the presence of a urinary catheter nearly doubled the risk of emergence agitation. Conclusion Emergence agitation following general anesthesia is a common complication in adult nasal surgery patients. To reduce the occurrence and consequences of agitation episodes, elimination of the associated risk factors is necessary, especially in at-risk patients.

Abstract
BACKGROUND Sevoflurane may be associated with neural toxicity in the developing brain, but the mechanism is still unclear. Phosphorylated extracellular signal-regulated kinases 1/2 (pERK1/2) are important for developing neurons. The aim of our study was to investigate the effects of sevoflurane on spatial learning and memory and on expression of pERK1/2 in hippocampus of neonatal rats. METHODS Sixty-three neonatal rats were randomly divided into three groups: control group, sevoflurane (sevo) group, and sham group. Rats in the control group were placed in a plastic chamber flushed continuously for 4 h with air alone, rats in the sevo group were exposed in 5% sevoflurane and air for 4 h, and rats in the sham group were exposed in 5% carbon dioxide and air for 4 h, with identical flow rates for all groups. All three groups were subjected to Morris water maze test 1 day after sevoflurane exposure. Moreover, expression of pERK1/2 was determined by immunochemistry and Western blot at 1, 3, and 6 weeks after exposure. RESULTS Compared with the control group, the escape latency was longer in sevo group and the expression of pERK1/2 was significantly inhibited in the sevo group (P < 0.01); no differences between control and sham groups were observed. CONCLUSION Our study demonstrated that neonatal rats exposed to sevoflurane had impaired spatial learning and memory, and this may be attributed to decreased pERK1/2 in the hippocampus.

Abstract
BACKGROUND Sevoflurane is an inhaled volatile anaesthetic that is widely used in paediatric anaesthetic practice. Since its introduction, postoperative behavioural disturbance known as emergence agitation (EA) or emergence delirium (ED) has been recognized as a problem that may occur during recovery from sevoflurane anaesthesia. For the purpose of this systematic review, EA has been used to describe this clinical entity. A child with EA may be restless, may cause self-injury or may disrupt the dressing, surgical site or indwelling devices, leading to the potential for parents to be dissatisfied with their child's anaesthetic. To prevent such outcomes, the child may require pharmacological or physical restraint. Sevoflurane may be a major contributing factor in the development of EA. Therefore, an evidence-based understanding of the risk/benefit profile regarding sevoflurane compared with other general anaesthetic agents and adjuncts would facilitate its rational and optimal use. OBJECTIVES To compare sevoflurane with other general anaesthetic (GA) agents, with or without pharmacological or non-pharmacological adjuncts, with regard to risk of EA in children during emergence from anaesthesia. The primary outcome was risk of EA; secondary outcome was agitation score. SEARCH METHODS We searched the following databases from the date of inception to 19 January 2013: CENTRAL, Ovid MEDLINE, Ovid EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (EBSCOhost), Evidence-Based Medicine Reviews (EBMR) and the Web of Science, as well as the reference lists of other relevant articles and online trial registers. SELECTION CRITERIA We included all randomized (or quasi-randomized) controlled trials investigating children < 18 years of age presenting for general anaesthesia with or without surgical intervention. We included any study in which a sevoflurane anaesthetic was compared with any other GA, and any study in which researchers investigated adjuncts (pharmacological or non-pharmacological) to sevoflurane anaesthesia compared with no adjunct or placebo. DATA COLLECTION AND ANALYSIS Two review authors independently searched the databases, decided on inclusion eligibility of publications, ascertained study quality and extracted data. They then resolved differences between their results by discussion. Data were entered into RevMan 5.2 for analyses and presentation. Comparisons of the risk of EA were presented as risk ratios (RRs) with 95% confidence intervals (CIs). Sevoflurane is treated as the control anaesthesia in this review. Sensitivity analyses were performed as appropriate, to exclude studies with a high risk of bias and to investigate heterogeneity. MAIN RESULTS We included 158 studies involving 14,045 children. Interventions to prevent EA fell into two broad groups. First, alternative GA compared with sevoflurane anaesthesia (69 studies), and second, use of an adjunct with sevoflurane anaesthesia versus sevoflurane without an adjunct (100 studies). The overall risk of bias in included studies was low. The overall Grades of Recommendation, Assessment, Development and Evaluation Working Group (GRADE) assessment of the quality of the evidence was moderate to high. A wide range of EA scales were used, as were different levels of cutoff, to determine the presence or absence of EA. Some studies involved children receiving potentially inadequate or no analgesia intraoperatively during painful procedures.Halothane (RR 0.51, 95% CI 0.41 to 0.63, 3534 participants, high quality of evidence) and propofol anaesthesia were associated with a lower risk of EA than sevoflurane anaesthesia. Propofol was effective when used throughout anaesthesia (RR 0.35, 95% CI 0.25 to 0.51, 1098 participants, high quality of evidence) and when used only during the maintenance phase of anaesthesia after sevoflurane induction (RR 0.59, 95% CI 0.46 to 0.76, 738 participants, high quality of evidence). No clear evidence was found of an effect on risk of EA of desflurane (RR 1.46, 95% CI 0.92 to 2.31, 408 participants, moderate quality of evidence) or isoflurane (RR 0.76, 95% CI 0.46 to 1.23, 379 participants, moderate quality of evidence) versus sevoflurane.Compared with no adjunct, effective adjuncts for reducing the risk of EA during sevoflurane anaesthesia included dexmedetomidine (RR 0.37, 95% CI 0.29 to 0.47, 851 participants, high quality of evidence), clonidine (RR 0.45, 95% CI 0.31 to 0.66, 739 participants, high quality of evidence), opioids, in particular fentanyl (RR 0.37, 95% CI 0.27 to 0.50, 1247 participants, high quality of evidence) and a bolus of propofol (RR 0.58, 95% CI 0.38 to 0.89, 394 participants, moderate quality of evidence), ketamine (RR 0.30, 95% CI 0.13 to 0.69, 231 participants, moderate quality of evidence) or midazolam (RR 0.57, 95% CI 0.41 to 0.81, 116 participants, moderate quality of evidence) at the end of anaesthesia. Midazolam oral premedication (RR 0.81, 95% CI 0.59 to 1.12, 370 participants, moderate quality of evidence) and parental presence at emergence (RR 0.91, 95% CI 0.51 to 1.60, 180 participants, moderate quality of evidence) did not reduce the risk of EA.One or more factors designated as high risk of bias were noted in less than 10% of the included studies. Sensitivity analyses of these studies showed no clinically relevant changes in the risk of EA. Heterogeneity was significant with respect to these comparisons: halothane; clonidine; fentanyl; midazolam premedication; propofol 1 mg/kg bolus at end; and ketamine 0.25 mg/kg bolus at end of anaesthesia. With investigation of heterogeneity, the only clinically relevant changes to findings were seen in the context of potential pain, namely, the setting of adenoidectomy/adenotonsillectomy (propofol bolus; midazolam premedication) and the absence of a regional block (clonidine). AUTHORS' CONCLUSIONS Propofol, halothane, alpha-2 agonists (dexmedetomidine, clonidine), opioids (e.g. fentanyl) and ketamine reduce the risk of EA compared with sevoflurane anaesthesia, whereas no clear evidence shows an effect for desflurane, isoflurane, midazolam premedication and parental presence at emergence. Therefore anaesthetists can consider several effective strategies to reduce the risk of EA in their clinical practice. Future studies should ensure adequate analgesia in the control group, for which pain may be a contributing or confounding factor in the diagnosis of EA. Regardless of the EA scale used, it would be helpful for study authors to report the risk of EA, so that this might be included in future meta-analyses. Researchers should also consider combining effective interventions as a multi-modal approach to further reduce the risk of EA.

Abstract
BACKGROUND Early negative postoperative behavior (e-PONB) is common in children and manifests itself as emergence agitation (EA), emergence delirium (ED), and pain. The objective of this prospective double blind, randomized, placebo-controlled trial was to determine whether IV clonidine or IV fentanyl prior to surgery modifies e-PONB in children. METHODS Ninety children scheduled for subumbilical surgery under sevoflurane anesthesia supplemented with regional anesthesia were randomized to either receive IV clonidine 2 mcg·kg(-1) , IV fentanyl 2 mcg·kg(-1) or placebo (IV saline) before surgery. Primary outcome measures were the incidence of EA, ED and pain during the first hour after awakening. Secondary outcome measures were side effects such as nausea and vomiting and delayed discharge from PACU. RESULTS Eighty-seven children (n = 29 per group) completed the study. EA was present in 10 children (six clonidine, none fentanyl, and four placebo, P = 0.04) whereas ED was observed in 20 children (nine clonidine, three fentanyl, and eight placebo P = 0.13). Sixteen children who received placebo had a CHIPPS score of ≥4 compared with nine children in fentanyl group and 18 children receiving clonidine (P = 0.04). Ten children receiving fentanyl vomited during the first postoperative day, compared with six children in placebo group and none in clonidine group (P = 0.003). Discharge from PACU was not affected. CONCLUSIONS IV fentanyl before surgery but not IV clonidine modifies e-PONB in children undergoing lower abdominal surgery under general anesthesia supplemented with regional anesthesia. The use of fentanyl in this population was also associated with reduced pain scores after awakening but with significantly greater incidence of PONV.

Abstract
Abstract
Background:
Midazolam has been widely studied for preventing emergence agitation. The authors previously reported that in children with sevoflurane anesthesia, intravenous administration of midazolam (0.05 mg/kg) before the end of surgery reduced the incidence of emergence agitation but prolonged the emergence time. This study was designed to test the hypothesis that a lower midazolam dose could suppress emergence agitation with minimal disturbance of the emergence time in children with sevoflurane anesthesia.
Methods:
In this randomized, double-blind, placebo-controlled trial, 90 children (1 to 13 yr of age) having strabismus surgery were randomized to 1:1:1 to receive 0.03 mg/kg of midazolam, 0.05 mg/kg of midazolam, or saline just before the end of surgery. The primary outcome, the incidence of emergence agitation, was evaluated by using the pediatric anesthesia emergence delirium scale and the four-point agitation scale. The secondary outcome was time to emergence, defined as the time from sevoflurane discontinuation to the time to extubation.
Results:
The incidence of emergence agitation was lower in patients given 0.03 mg/kg of midazolam (5 of 30, 16.7%) and patients given 0.05 mg/kg of midazolam (5 of 30, 16.7%) compared with that in patients given saline (13/of 30, 43.3%; P = 0.036 each). The emergence time was longer in patients given 0.05 mg/kg of midazolam (17.1 ± 3.4 min, mean ± SD) compared with that in patients given 0.03 mg/kg of midazolam (14.1 ± 3.6 min; P = 0.0009) or saline (12.8 ± 4.1 min; P = 0.0003).
Conclusion:
Intravenous administration of 0.03 mg/kg of midazolam just before the end of surgery reduces emergence agitation without delaying the emergence time in children having strabismus surgery with sevoflurane anesthesia. (Anesthesiology 2014; 120:1354-61)

Abstract
Anesthetic neurotoxicity has been a hot topic in anesthesia for the past decade. It is of special interest to pediatric anesthesiologists. A subgroup of children potentially at greater risk for anesthetic neurotoxicity, based on a prolonged anesthetic exposure early in development, are those children receiving anesthesia for surgical repair of congenital heart disease. These children have a known risk of neurologic deficit after cardiopulmonary bypass for surgical repair of congenital heart disease. Yet, the type of anesthesia used has not been considered as a potential etiology for their neurologic deficits. These children not only receive prolonged anesthetic exposure during surgical repair, but also receive repeated anesthetic exposures during a critical period of brain development. Their propensity to abnormal brain development, as a result of congenital heart disease, may modify their risk of anesthetic neurotoxicity. This review article provides an overview of anesthetic neurotoxicity from the perspective of a pediatric cardiac anesthesiologist and provides insight into basic science and clinical investigations as it relates to this unique group of children who have been studied over several decades for their risk of neurologic injury.

Abstract
This randomised, controlled, double-blind study investigated the effects of intra-operative magnesium sulphate administration on the incidence of emergence agitation in children undergoing adenotonsillectomy using sevoflurane anaesthesia. Seventy children were randomly allocated to receive a 30 mg.kg(-1) bolus of intravenous magnesium sulphate after induction of anaesthesia followed by a continuous infusion of 10 mg.kg(-1).h(-1) or an equal volume of saline 0.9%. All children received titrated sevoflurane anaesthesia adjusted to maintain haemodynamic stability. The Pediatric Anesthesia Emergence Delirium scale and the Children's Hospital of Eastern Ontario Score were used for the assessment of postoperative emergence agitation and pain, respectively. Emergence agitation was more common in the control group than in the magnesium group (23 (72%) and 12 (36%), respectively (p = 0.004)), with a relative risk of 0.51 (95% CI 0.31-0.84), an absolute risk reduction of 0.35 (95% CI 0.10-0.54), and number needed to treat of 3 (95% CI 2-9). Postoperative pain scores were comparable in the two groups. Magnesium sulphate reduces the incidence and severity of emergence agitation in children undergoing adenotonsillectomy using sevoflurane anaesthesia and is not associated with increased postoperative side-effects or delayed recovery.

Abstract
OBJECTIVES/AIM This randomized control trial was designed to evaluate the incidence of emergence delirium (ED) in preschool children receiving sevoflurane or desflurane anesthesia combined with an effective caudal block. BACKGROUND While ED has been described in children receiving sevoflurane or desflurane anesthesia, a direct comparison between the two agents using a validated ED assessment tool has not been reported previously. METHODS/MATERIALS Two hundred and sixty preschool children scheduled for elective sub-umbilical surgery were randomized to receive sevoflurane or desflurane anesthesia combined with a caudal block. ED was defined as a Paediatric Anesthesia Emergence Delirium scale (PAED) ≥ 10 points. A delirium-specific score (ED I) was calculated from the first three items of the PAED score (eye contact, purposeful actions, awareness of the surroundings) and a nonspecific score (ED II) from the last two items on the PAED score (restlessness and inconsolability) to test the hypothesis that some items of the PAED scale may better reflect clinical ED than others. RESULTS Thirty-one (25%) children in each group demonstrated ED after awakening with ED being of shorter duration in the desflurane group than the sevoflurane group. An ED I score of nine points had a sensitivity of 0.93 and a specificity of 0.94 for ED. An ED II score of five points had a sensitivity of 0.34 and specificity of 0.95 for ED. CONCLUSION Sevoflurane and desflurane anesthesia were associated with similar incidences of ED in children undergoing sub-umbilical surgery and receiving effective regional anesthesia. High scores on the first three items of the PAED scale were highly correlated with ED. The items restlessness and inconsolability had lower sensitivity for the diagnosis of ED.

Abstract
INTRODUCTION The practice of pediatric anesthesia requires a regular update of scientific knowledge and technical skills. To provide the most adequate Continuing Medical Education programs, it is necessary to assess the practices of pediatric anesthesiologists. Thus, the objective of this survey was to draw a picture of the current clinical practices of general anesthesia in children, in France. MATERIAL AND METHODS One thousand one hundred and fifty questionnaires were given to anesthesiologists involved in pediatric cases. These questionnaires collected information on various aspects of clinical practice relative to induction, maintenance, recovery from general anaesthesia and also classical debated points such as children with Upper Respiratory Infection (URI), emergence agitation, epileptoid signs or anaesthetic management of adenoidectomy. Differences in practices between CHG (general hospital), CHU (teaching hospital), LIBERAL (private) and PSPH (semi-private) hospitals were investigated. RESULTS There were 1025 questionnaires completed. Fifty-five percent of responders worked in public hospitals (CHG and CHU); 77% had a practice that was 25% or less of pediatric cases. In children from 3 to 10 years: 72% of respondents used always premedication and two thirds performed inhalation induction in more than 50% of cases. For induction, 53% used sevoflurane (SEVO) at 7 or 8%. Respondents from LIBERAL used higher SEVO concentrations. Tracheal intubation was performed with SEVO alone (37%), SEVO and propofol (55%) and SEVO with myorelaxant (8%), 93% of respondents used a bolus of opioid. For maintenance, the majority of respondents used SEVO associated with sufentanil; desflurane and remifentanil were more frequently used in CHU. Two thirds of respondents used N(2)O. Depth of anesthesia was commonly assessed by hemodynamic changes (52%), end tidal concentration of halogenated (38%) or automated devices based on EEG (7%). In children with URI, 98% of respondents used SEVO for anesthesia. To control the airway 42% used a tracheal tube, 30% a laryngeal mask and 20% a facial mask. Emergence agitation was an important concern for two thirds of respondents, while epileptoid signs were considered as important by only 20%. Eighty-nine percent of respondents practiced anesthesia for adenoidectomy. Anesthesia was induced by inhalation of SEVO 7-8% (41%), 6% (39%) or 4% (12%), 66% put an intravenous line (less frequently in LIBERAL). 67% of the responders managed adenoidectomy without any device to control the airway (more frequently in LIBERAL), 32% administrated a bolus of opioid (less frequently in LIBERAL). DISCUSSION This survey demonstrated that the practices regarding general anesthesia in children are relatively homogenous. Most of the differences appeared between LIBERAL and the others structures; the anaesthetic management for adenoidectomy illustrates these findings.

Abstract
BACKGROUND AND OBJECTIVES The use of sevoflurane in pediatric anesthesia, which could enable a more rapid emergence and recovery, is complicated by the frequent occurrence of post-anesthesia agitation. This study aims to test the efficacy of adding a low dose of ketamine orally, as a supplement to the midazolam-based oral premedication for reducing sevoflurane-related emergence agitation. MATERIALS AND METHODS Ninety-two preschool children, aged between two and six years, with an American Society of Anesthesiologists physical status I or II, scheduled for elective dental filling and extractions under general anesthesia were included. The patients were allocated into two groups: Group M (46 patients) received oral midazolam 0.5 mg/kg, mixed with ibuprofen 10 mg/kg, while group KM (46 patients) received a similar premedication mixture, in addition to ketamine 2 mg/kg. The acceptance of the drug mixture, the onset of action, and the occurrence of vomiting were monitored over the next 30 minutes. Induction of anesthesia was carried out using sevoflurane 8 Vol% in 100% oxygen via face mask. Anesthesia was maintained with sevoflurane 1.5-2 Vol% in an oxygen-nitrous oxide mixture. After extubation, the standard scoring scale was used for assessing the quality of emergence. Agitation parameters were measured using a five-point scale. Agitated children were managed by giving intravenous increments of fentanyl 1 mug/ kg. The time of hospital discharge allowance was recorded. RESULTS Drug palatability, vomiting, and onset of action of premedication; showed no significant differences between both groups. Time of eye opening after discontinuation of sevoflurane showed no significant differences between both groups. Postoperative agitation score and rescue fentanyl consumption were higher in group M than in group KM on admission to the PACU (P < 0.01). The time of hospital discharge allowance in group M was longer than in group KM (P < 0.05). CONCLUSION Adding a low dose of oral ketamine to midazolam-based oral premedication in preschool children undergoing dental surgery reduced sevoflurane-related emergence agitation without delaying discharge.

Abstract
In this prospective, placebo-controlled study, we evaluated the effect of prophylactic ondansetron therapy on emergence agitation of children who underwent minor surgery below the umbilicus. Seventy children aged one to six years and American Society of Anesthesiologists physical status I were studied. Children were premedicated with midazolam rectally and were randomly assigned to receive either ondansetron (Group O) or placebo (Group P) in combination with caudal anaesthesia. Children in Group O received intravenous ondansetron (0.1 mg/kg for children weighing <40 kg, 4 mg for children weighing >40 kg) and Group P (n=35) received normal saline 2 ml following anaesthesia induction with sevoflurane. Airway management was provided with LMA-Proseal without muscle relaxation and anaesthesia maintenance was provided with a 60:40 N2O:O2 mixture and sevoflurane. Emergence agitation was evaluated with a ten point scale and pain level was assessed every 10 minutes for the first 30 minutes after admission to the recovery room. There were no significant differences between the placebo and ondansetron groups with respect to demographic, anaesthetic and surgical details. Incidences of emergence agitation in ondansetron and placebo groups were similar (32.4% and 30.3% at 10 minutes respectively). Mean modified Children's Hospital of Eastern Ontario pain scale scores and mean ten-point scale scores and emergence agitation incidences decreased similarly after 10 minutes in both groups. Ready time for discharge was similar between the groups. Agitated patients had significantly increased ready time for discharge compared to non-agitated patients (P=0.001). Prophylactic intravenous ondansetron administration does not reduce emergence agitation comparing to placebo after sevoflurane anaesthesia.

Abstract
It has been assumed that anaesthetics have minimal or no persistent effects after emergence from anaesthesia. However, general anaesthetics act on multiple ion channels, receptors, and cell signalling systems in the central nervous system to produce anaesthesia, so it should come as no surprise that they also have non-anaesthetic actions that range from beneficial to detrimental. Accumulating evidence is forcing the anaesthesia community to question the safety of general anaesthesia at the extremes of age. Preclinical data suggest that inhaled anaesthetics can have profound and long-lasting effects during key neurodevelopmental periods in neonatal animals by increasing neuronal cell death (apoptosis) and reducing neurogenesis. Clinical data remain conflicting on the significance of these laboratory data to the paediatric population. At the opposite extreme in age, elderly patients are recognized to be at an increased risk of postoperative cognitive dysfunction (POCD) with a well-recognized decline in cognitive function after surgery. The underlying mechanisms and the contribution of anaesthesia in particular to POCD remain unclear. Laboratory models suggest anaesthetic interactions with neurodegenerative mechanisms, such as those linked to the onset and progression of Alzheimer's disease, but their clinical relevance remains inconclusive. Prospective randomized clinical trials are underway to address the clinical significance of these findings, but there are major challenges in designing, executing, and interpreting such trials. It is unlikely that definitive clinical studies absolving general anaesthetics of neurotoxicity will become available in the near future, requiring clinicians to use careful judgement when using these profound neurodepressants in vulnerable patients.

Abstract
OBJECTIVES The aim of this study was to determine whether the concurrent use of either of a subhypnotic dose of midazolam, propofol or ketamine with fentanyl just before discontinuing the sevoflurane anesthesia would effectively sedate the children as they recovered and significantly decrease the incidence and severity of emergence agitation and would not delay patient awakening and discharge. BACKGROUND Postoperative emergence agitation may occur in children after general anesthesia with volatile anesthetics. Children who undergo cataract surgery after sevoflurane induction and sevoflurane-remifentanil maintenance may experience this type of agitation. METHODS/MATERIALS In 120 un-premedicated children aged 1-7 years, mask induction with sevoflurane was performed and they were then randomly assigned to one of the three antiagitation postoperative groups (n = 40). We studied the postoperative antiagitation effects of subhypnotic doses of midazolam combined with fentanyl, propofol with fentanyl or ketamine with fentanyl administered just before discontinuing the sevoflurane anesthesia. A score for the level of agitation can be assigned based on the recovery mental state (RMS) scale and the recently published pediatric anesthesia emergence delirium scale (PAED). Postoperative factors assessed included emergence behaviors, the time to eye opening, the time to discharge from the postanesthesia care unit (PACU) to the ward. RESULTS There were significantly more agitated children in the ketamine-group when compared to the midazolam-group or to the propofol-group at all time P < 0.05), especially at 10 and 15 min. The PAED scale showed a significant advantage for midazolam-fentanyl [5 (2-15)] and propofol-fentanyl [6 (3-15)] versus ketamine-fentanyl [10 (3-20)] (P < 0.05). The time to discharge from the PACU to the ward was not significantly different among the groups. CONCLUSIONS Intravenous administration of a subhypnotic dose of midazolam or propofol in addition to a low dose of fentanyl just before discontinuing the sevoflurane anesthesia was both effective on decreasing the incidence and severity of emergence agitation in children undergoing cataract extraction without significant delaying recovery time and discharge. The effect of midazolam was clearer than that seen with propofol.

Abstract
Background The rapid emergence and recovery from general anesthesia afforded by sevoflurane is associated with a high incidence of emergence agitation in children. Small doses of ketamine reduce the incidence of emergence agitation. This study compared the effects of ketamine 0.25 mg/kg and 0.5 mg/kg on emergence agitation and postoperative pain. Methods The effects of added intravenous ketamine were evaluated in 93 children, ASA I-II, 2-14 years old, undergoing an adenotonsillectomy. The patients were allocated randomly to one of three groups receiving saline (group C), ketamine 0.25 mg/kg (group K0.25) or ketamine 0.5 mg/kg (group K0.5). The children in each group were administered the study drugs 10 minutes before the end of surgery. The recovery characteristics, including the time to extubation, delivery time from the PACU, postoperative nausea and vomiting, agitation and pain were assessed. Results There were no significant differences in the extubation time, delivery time and postoperative nausea and vomiting between the three groups. There were significant differences in modified CHEOPS (Children's Hospital of Eastern Ontario Pain Scale) between the three groups. The incidence of emergence agitation was low in the K0.25 and K0.5 groups compared to the control group. However, there was no significant difference between the K0.25 and K0.5 groups. Conclusions There was no significant difference in the incidence of emergence agitation between K0.25 and K0.5 groups. However, K0.5 group showed a lower pain score than K0.25 group.

Abstract
BACKGROUND Emergence agitation (EA) in children is increased after sevoflurane anaesthesia. The efficacy of prophylactic treatment is controversial. The aim of this study was to provide a meta-analysis of the studies of the pharmacological prevention of EA in children. METHODS A comprehensive literature search was conducted to identify clinical trials that focused on the prevention of EA in children anaesthetized with sevoflurane, desflurane, or both. The data from each trial were combined using the Mantel-Haenszel model to calculate the pooled odds ratio (OR) and 95% confidence interval. I(2) statistics were used to assess statistics heterogeneity and the funnel plot and the Begg-Mazumdar test to assess bias. RESULTS Thirty-seven articles were found which included a total of 1695 patients in the intervention groups and 1477 in the control ones. Midazolam and 5HT(3) inhibitors were not found to have a protective effect against EA [OR=0.88 (0.44, 1.76); OR=0.39 (0.12, 1.31), respectively], whereas propofol [OR=0.21 (0.16, 0.28)], ketamine [OR=0.28 (0.13, 0.60)], alpha(2)-adrenoceptors [OR=0.23 (0.17, 0.33)], fentanyl [OR=0.31 (0.18, 0.56)], and peroperative analgesia [OR=0.15 (0.07, 0.34)] were all found to have a preventive effect. Subgroup analysis according to the peroperative analgesia given does not affect the results. CONCLUSIONS This meta-analysis found that propofol, ketamine, fentanyl, and preoperative analgesia had a prophylactic effect in preventing EA. The analgesic properties of these drugs do not seem to have a role in this effect.

Abstract
BACKGROUND Emergence delirium (ED) is a common problem in children recovering from general anesthesia. ED causes disruption in the postanesthetic care unit, making nursing and monitoring more difficult, and is potentially dangerous to the child. The greatest hindrance to understanding ED was the lack of a standardized tool to assess it. The Pediatric Anesthesia Emergence Delirium (PAED) Scale was recently described to measure the degree of ED in children. In this prospective observational study, we sought to evaluate the incidence of ED by grading emergence behavior using the PAED Score in healthy Asian children undergoing outpatient surgery. METHODS Three hundred sixteen children aged 2-12 years undergoing general anesthesia for elective outpatient surgery were included. No premedication was administered. Induction behavior was graded using the induction compliance checklist, and the presence of any excitation on induction documented. Emergence behavior was recorded using the PAED Scale, and the children were separately assessed for clinical agitation. RESULTS One hundred and thirty-six children (43%) had PAED Scores >0 and 33 (10.4%) had PAED Scores of >or=10. Only 28 children (8.9%) had clinical agitation consistent with ED, the rest were agitated for other reasons. A score of >or=10 on the PAED Scale was the best discriminator between presence and absence of clinical agitation. The area under the receiver operating characteristic curve for PAED Score of >or=10 was 0.98, with a true-positive rate (sensitivity) of 0.85 and a false-positive rate (1-specificity) of 0.041. Four factors were found to be predictive of ED. These include young age, poor compliance at induction, lack of intraoperative fentanyl use and rapid time to awakening. CONCLUSIONS The incidence of ED is approximately 10% in our population of healthy, unpremedicated Asian children undergoing day surgery. Young age, poor compliance at induction, lack of intraoperative fentanyl use and rapid time to awakening were predictive risk factors for ED in our population. A PAED Score of >or=10 was correlated with clinically significant ED and appeared to be the ideal cutoff score for ED.

Abstract
BACKGROUND Emergence agitation or delirium is a known phenomenon that may occur in children undergoing general anesthesia with inhaled agents. Our aim was to test the hypothesis that the addition of a small dose of ketamine at the end of sevoflurane anesthesia will result in a decrease in the incidence and severity of such phenomenon. METHODS We performed a randomized double blind study involving 85 premedicated children 4-7 years old undergoing dental repair. Children were premedicated with acetaminophen and midazolam. Anesthesia was induced and maintained with sevoflurane in N2O/O2. Group K received ketamine 0.25 mg.kg (-1) and Group S received saline. We evaluated recovery characteristics upon awakening and during the first 30 min using the Pediatric Anesthesia Emergence Delirium scale. RESULTS Eighty of the 85 enrolled children completed the study. There were 42 children in Group I. Emergence agitation was diagnosed in seven children in the ketamine group (16.6%) and in 13 children in the placebo group (34.2%). There was no difference in time to meet recovery room discharge criteria between the two groups. CONCLUSIONS We conclude that the addition of ketamine 0.25 mg.kg(-1) can decrease the incidence of emergence agitation in children after sevoflurane general anesthesia.

Abstract
BACKGROUND The aim of this study was an improvement in patient comfort, reduction of anaesthesia costs and room contamination by the use of propofol for adenoidectomy. METHODS A total of 103 infants (aged 1-5 years) undergoing elective adenoidectomy were randomized for anaesthesia with sevoflurane-nitrous oxide/oxygen (group 1), sevoflurane-air/alfentanil (group 2), alfentanil-propofol under induction with sevoflurane (group 3) or alfentanil-propofol (group 4). RESULTS Using propofol, postoperative agitation and emesis were significantly less and the anaesthesia costs as well as the need for analgesics was reduced compared to inhalative anaesthesia. CONCLUSIONS The use of propofol for preschool children undergoing ear, nose and throat (ENT) surgery seems to be advantageous because of less postoperative agitation, emesis and costs.
