Abstract
INTRODUCTION Pediatric dental surgeries are associated with the emotions of fear, anxiety, and other behavioral disturbances of children that need to be managed. Sedation using drugs like dexmedetomidine (DEX) and midazolam (MID) is a common pharmacological behavior managing technique. We conducted this meta-analysis to evaluate the efficacy of both these drugs in current literature. METHODOLOGY A thorough literature search was conducted on PubMed, MEDLINE, Google Scholar, and Cochrane's database for randomized studies that compared sedative efficacy of dexmedetomidine with midazolam in children of 0-15 years of age undergoing dental surgeries. Sedation in children during dental procedure, when used as a premedication, at the time of separation from parents and at the time of mask induction, onset time, duration of anesthesia, and surgery were evaluated. The mean differences (MDs), odds ratio (OR), and their 95% confidence intervals (CIs) were calculated both for continuous and dichotomous outcome data using random-effects model. RESULTS Seven studies met out inclusion criteria and were analyzed. Results of premedication with DEX was associated with more anxiolysis (OR=0.29, 95% CI: 0.17-0.52, p=0.0001; I2=0%) and at the time of separation from parents (OR=0.36, 95% CI: 0.19-0.69, p=0.002; I2=52%) in comparison to MID. No significant differences in results were seen at mask induction (OR=0.63, 95% CI: 0.34-1.18, p=0.15; I2=47%) and for sedation in children during dental procedures (OR=0.52, 95% CI: 0.07-3.70, p=0.51; I2=72%). Also, there were no significant differences in onset time, duration of anesthesia, and surgery between the two agents. CONCLUSION DEX proved to be a better premedicant than MID for pediatric patients. No significant difference in efficacy of both sedative agents was observed in children undergoing dental treatment. More clinical trials need to be conducted to see its efficacy in dental surgeries in children of standardized ages and with standard doses.

Abstract
OBJECTIVE To determine the effect of premedication with intramuscular midazolam on patient satisfaction in women undergoing general anaesthesia. TRIAL DESIGN, SETTING AND PARTICIPANTS Double-blind, parallel randomised control trial at a tertiary care medical centre in South Korea. Initially, 140 women aged 20-65 years who underwent general anaesthesia and had an American Society of Anesthesiology physical status classification of I or II were randomly assigned to the intervention group or the control group, and 134 patients (intervention n=65; control n=69) completed the study. INTERVENTION Intramuscular administration of midazolam (0.05 mg/kg) or placebo (normal saline 0.01 mL/kg) on arrival at the preoperative holding area. MAIN OUTCOMES The primary outcome was the patient's overall satisfaction with the anaesthesia experience as determined by questionnaire responses on the day after surgery. Satisfaction was defined as a response of 3 or 4 on a five-point scale (0-4). The secondary outcomes included blood pressure, heart rate, oxygen desaturation, recovery duration and postoperative pain. RESULTS Patients who received midazolam were more satisfied than those who received placebo (percentage difference: 21.0%, OR 3.56, 95% CI 1.46 to 8.70). A subgroup analysis revealed that this difference was greater in patients with anxiety, defined as those whose Amsterdam Preoperative Anxiety and Information Scale anxiety score was ≥11, than that for the whole sample population (percentage difference: 24.0%, OR 4.33, 95% CI 1.25 to 14.96). Both groups had similar heart rates, blood pressure and oxygen desaturation. CONCLUSION Intramuscular administration of midazolam in women before general anaesthesia in the preoperative holding area improved self-reported satisfaction with the anaesthesia experience, with an acceptable safety profile.

Abstract
BACKGROUND Most patients experiencing preoperative anxiety would welcome support in coping with their anxiety. Anxiolytic medication is a common way to address preoperative anxiety. However, the proportion of patients who welcome anxiolytic medication preoperatively and the preferred time of taking it have not been studied thoroughly. METHODS Adult patients (n = 1000) scheduled to undergo elective surgery under general anesthesia were eligible to participate in this single-center observational study. Primary outcomes were the ratio of patients desiring anxiolytic medication (no/yes/on request) and the preferred time of taking it (evening before surgery/morning of day of surgery/on call to the operating room). Secondary outcomes included associations between different measures of anxiety (i.e., anxiety level according to the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and anxiety status (no/yes)) and desire for anxiolytic medication (no/yes/on request). Primary outcomes were analyzed descriptively, and secondary outcomes were analyzed using multinomial logistic regressions. RESULTS Three hundred fifty-six (35.6%) out of 1000 patients desired anxiolytic medication and 239 (23.9%) patients would welcome anxiolytic medication on request. In patients reporting anxiety (no/yes; n = 493), 228 (46.2%) stated a clear desire for anxiolytic medication (yes) and 142 (28.8%) considered anxiolytic medication (on request). Patients' preferences concerning the timing of premedication vary widely. In patients reporting a clear desire for anxiolytic medication (n = 356), the "morning of the day of surgery" was most frequently (n = 111, 31.2%) stated as the preferred time to get anxiolytic medication, followed by "on call to the operating room" (n = 51, 14.3%). All anxiety measures were significantly associated with desire for anxiolytic medication (p < 0.05). CONCLUSIONS Given the importance of preoperative anxiety to patients, patients' desire for anxiolytic medication should be considered when discussing the pros and cons of premedication. Individualized instead of standardized prescription and timing of premedication is recommended. TRIAL REGISTRATION German Clinical Trials Register ( DRKS 00013319 , approved 23/11/2017).

Abstract
Background Dental phobia and apprehension in children lead to difficulty with behavior management. During dental procedure if a child had a bad experience, he will develop greater apprehension, which makes further treatment difficult. Aim and objective The aim and objective of the present study is to assess and compare the sedation and wake-up behavior status of oral combinations of three different doses of ketamine and midazolam drugs in three different groups mixed in 1 mL of honey. Methodology This study was a randomized, clinical study that included patients ranging from 3 to 9 years of age with American Society of Anesthesiologists–I status with carious teeth, were randomly allocated among three groups where group (A) received 0.2 mg/kg of oral midazolam and 5 mg/kg oral ketamine combination drugs, group (B) received 0.3 mg/kg of oral midazolam with 3 mg/kg of oral ketamine combination drugs and group (C) received 0.4 mg/kg of oral midazolam with 2 mg/kg of oral ketamine combination drugs mixed in 1 mL of honey. Child patient's who fulfilled the inclusion criteria, heart rate, blood pressure, and oxygen saturation was recorded from starting of the treatment until discharged from the monitoring room. Ease of treatment completion was evaluated according to the Houpt scale, patients’ behavior, sedation, and wake-up behavior status were evaluated with modified observer assessment of alertness and sedation scale (MOAAS). Results In the study, various doses of ketamine-midazolam combination drugs in three different groups resulted in a clement increase in heart rate, systolic blood pressure (SBP), and diastolic blood pressure (DBP) during the procedure but variations among the groups were not significant. As per MOAAS, the sedation success rate in group B (83.3%) was more than group A (66.6%) and group C (66.6%). All the three groups equally showed the same i.e., (91.6%), behavior score during treatment. Ease of treatment completion was excellent in group B (83.3%) followed by group A and group C [i.e.], (66.7%). Whereas, wake-up behavior score as per MOAAS scale was found to be calm and cooperative in group B (91.7%) followed by group C (88.9%) and group A (83.3%). Conclusion In the present study oral ketamine-midazolam combination drugs can be used without harm and effectively as moderate sedation in an uncooperative pediatric patient.

Abstract
BACKGROUND Midazolam is used for sedation before diagnostic and therapeutic medical procedures by several routes including oral, intravenous, intranasal and intramuscular. This is an update of a Cochrane review published in 2016, which aimed to determine the evidence on the effectiveness of midazolam for sedation when administered before a diagnostic or therapeutic procedure in adults and children. METHODS We searched CENTRAL, MEDLINE, Embase and two trials registers up to May 2020 together with reference checking to identify additional studies. We imposed no language restrictions. Randomized controlled trials of midazolam in comparison with placebo or other medications used for sedation were included. Two authors independently extracted data and assessed risk of bias for each included study. RESULTS Eight new trials were included in this update, which resulted in changed conclusions for the intravenous midazolam versus placebo, oral midazolam versus chloral hydrate and oral midazolam versus placebo comparisons. Effect estimates for all outcomes within the intravenous midazolam versus placebo (7 trials; 633 adults and 32 children) are uncertain due to concerns about imprecision and risk of bias. Midazolam resulted in a higher level of sedation than placebo (mean difference (MD) 1.05; 95% confidence interval (95% CI) 0.69 to 1.41; 1 study; 100 adults). There was no difference in anxiety (RR 0.43, 95% CI 0.09 to 1.99; I2 = 75%; 2 studies; 123 adults). Risk of difficulty performing procedures was lower in the midazolam group (RR 0.5; 95% CI 0.29 to 0.86; I2 = 45%; 3 studies; 191 adults and 32 children). There was no difference in discomfort (RR 0.51; 95% CI 0.25 to 1.04; I2 = 0%; 2 studies; 190 adults). Five trials with 336 children were included in the oral midazolam versus chloral hydrate comparison. Midazolam was less likely to result in moderate sedation (RR 0.30, 95% CI 0.11 to 0.82; I2 = 64%; 2 studies, 228 participants). This effect estimate is highly uncertain due to concerns about the risk of bias, imprecision and inconsistency. There was no difference in ratings of anxiety (SMD - 0.26; 95% CI - 0.75 to 0.23; I2 = 0%; 2 studies; 68 participants). Midazolam increased risk of incomplete procedures (RR 4.01; 95% CI 1.92 to 8.40; I2 = 0%; 4 studies, 268 participants). This effect estimate is uncertain due to concerns about the risk of bias. There were four trials with 359 adults and 77 children included in the oral midazolam versus placebo comparison. Midazolam reduced ratings of anxiety (SMD - 1.01; 95% CI - 1.86 to - 0.16; I2 = 92%; 4 studies; 436 participants). It is unclear if midazolam has an effect on difficulty performing procedures. Meta-analysis was not performed because there was only one incomplete procedure in the midazolam group in one of the trials. Midazolam reduced pain in one study with 99 adults (MD - 2; 95% CI - 2.5 to - 1.6; moderate quality). The effect estimate is uncertain due to concerns about the risk of bias. CONCLUSION The additional evidence arising from inclusion of new studies in this updated review has not produced sufficient high-quality evidence to determine whether midazolam produces more effective sedation than other medications or placebo in any specific population included in this review. For adults, there was low-quality evidence that intravenous midazolam did not reduce the risk of anxiety or discomfort/pain in comparison to placebo, but the sedation level was higher. By combining results from adults and children, there was low-quality evidence of a large reduction in the risk of procedures being difficult to perform with midazolam in comparison to placebo. The effect estimates for this comparison are uncertain because there was concern about risk of bias and imprecision. There is moderate-quality evidence suggesting that oral midazolam produces less-effective sedation than chloral hydrate for completion of procedures for children undergoing non-invasive diagnostic procedures. Ratings of anxiety were not different between oral midazolam and chloral hydrate. The extent to which giving oral midazolam to adults or children decreases anxiety during procedures compared with placebo is uncertain due to concerns about risk of bias and imprecision. There was moderate-quality evidence from one study that oral midazolam reduced the severity of discomfort/pain for adults during a brief diagnostic procedure in comparison with placebo.

Abstract
While most children have anxiety and fears in the hospital environment, especially prior to having surgery, there are several common behavioral and emotional disorders in children that can pose a challenge in the perioperative setting. These include anxiety, depression, oppositional defiant disorder, conduct disorder, attention deficit hyperactivity disorder, obsessive compulsive disorder, post-traumatic stress disorder, and autism spectrum disorder. The aim of this review article is to provide a brief overview of each disorder, explore the impact on anesthesia and perioperative care, and highlight some management techniques that can be used to facilitate a smooth perioperative course.

Abstract
Introduction: Midazolam is a water-soluble benzodiazepine which is frequently administered by intravenous and oral routes. Its nasal spray has become recently available. Materials and Methods: In this study, after obtaining clearance from the ethical committe, 66 patients between the age group of 4 and 10 years comparable in demographic variables were randomly allocated into two groups of 33 each. Group “O” received oral midazolam (0.5 mg/kg) 20 min before induction. Group “N” received intranasal midazolam (0.2 mg/kg) 20 min before induction. The heart rate and blood pressure (systolic, diastolic, and mean) and oxygen saturation (SPO2) were recorded. Statistical Analysis Used: The statistical analysis was done using SPSS (Statistical Package for the Social Sciences) version 15.0 software. The values were represented in number (%) and mean±sd. Results: Satisfactory sedation scores were better in nasal spray group than oral group. Satisfactory ease of induction scores, recovery times, and postanesthesia recovery scores were better in the nasal spray group than in the oral group. Conclusion: Nasal midazolam spray is acceptable and is a good alternative to oral midazolam as premedication in the pediatric population.

Abstract
Introduction: It is common to encounter a patient who is anxious to the magnitude that precludes the possibility of provision of dental treatment. This study aims to evaluate and compare the sedative effect of oral combinations of midazolam-ketamine (MK), dexmedetomidine-fentanyl (DF), and dexmedetomidine-ketamine (DK) in a group of uncooperative children requiring dental treatment. Methodology: This was a prospective, randomized, triple-blind study where 36 children who were 3–9 year old with American Society of Anesthesiologists –I status and presenting early childhood caries were randomly assigned to: Group A – 0.3 mg/kg of M and 5 mg/kg K, Group B – 2 ug/kg of D with 3 ug/kg of F, and Group C – 2ug/kg of D with 5 mg/kg of K in 1 mL honey. Patients' blood pressure, heart rate, and oxygen saturation were recorded from the start of the procedure till discharge. Patients' behavior, sedation status, and wake-up behavior were evaluated with Modified Observer Assessment of Alertness and Sedation Scale and ease of treatment completion by Houpt scale. Results: Hemodynamic changes were statistically insignificant in all three groups. 72.8% of patients in Group A and 58.3% of patients in Group B were successfully sedated during treatment. Behavior improvement was seen in all three groups during treatment with statistically insignificant difference in behavior scores produced by Group C. Ease of treatment completion was moderately better with Group A. Conclusion: Oral DK has a comparable sedative property with oral MK combination. Oral DF promises to be a potential sedative agent for children due to its successful anxiolysis.

Abstract
OBJECTIVES To evaluate the clinical efficacy of masking the odor of inhalational agents using fruit flavors on the anxiety behavior and compliance of children for inhalational induction. METHODS A prospective randomized double blind, placebo controlled study was conducted on 60 unpremedicated children in the age group of 4-12 y. Thirty children received anesthetic masks smeared with a flavor of child's choice while the other 30 children were induced using masks without flavor. Anxiety was assessed using modified Yale Pre-operative Anxiety Scale (mYPAS) in the pre-op room and during inhalational induction. Mask acceptance was graded by Induction Compliance Checklist (ICC). The cost-effectiveness of flavored anesthetic masks was compared to that of commercially available pre-scented masks. RESULTS The baseline anxiety in the two groups was comparable. The number of children demonstrating high levels of anxiety at anesthetic induction was similar in flavored and non-flavored mask groups (p 0.45). The compliance to mask induction was also equally good (p 0.99). The authors found significant difference in the cost of flavored mask (INR 56.45 per mask) as compared to commercially available pre-scented masks (INR 660 per mask). CONCLUSIONS The authors observed a placebo effect that reduced the pre-op anxiety in the control group which probably made the quality of induction equivalent with flavored and non-flavored masks. Therefore, using a flavored anesthetic mask is cost-effective than using a commercially available pre-scented mask.

Abstract
BACKGROUND Benzodiazepines have been used preoperatively as part of an anesthesia regimen to attenuate the anxiety of patients. In this study, we aimed to examine the effect of oral triazolam, a short-acting benzodiazepine, on anxiety, sedation, and amnesia. METHODS Ninety patients, aged 20-55 years, were randomly assigned to receive no premedication, or to receive triazolam 0.25 mg or 0.375 mg 1 h before anesthesia. Anxiety score, sedation score, blood pressure, heart rate and psychomotor performance were measured on the evening before surgery and on the day of surgery. Additional tests of psychomotor performance were performed in the postanesthesia care unit and on the next day of surgery. The occurrence of amnesia, bispectral index (BIS), recovery profiles and patient satisfaction with overall anesthesia care were also evaluated. RESULTS Changes in the anxiety and sedation scores on the day of surgery were not significantly different among groups, whereas the increases in systolic blood pressure and heart rate were significantly less in both triazolam groups. The triazolam groups both showed a higher incidence of high satisfaction scores (≥ 2). The two triazolam groups also showed similar outcomes, except for a dose-dependent increase in the number of patients with amnesia and BIS values < 90. Delayed recovery from general anesthesia and psychomotor impairment were not observed in the triazolam groups. CONCLUSIONS Triazolam 0.25 mg or 0.375 mg reduced the hemodynamic changes associated with anxiety, produced potent amnesia, and improved patient satisfaction. We suggest that triazolam can be used effectively as anesthetic premedication in adults.

Abstract
Background: Pharmacological methods have been used as an adjunct to enhance child cooperativeness and facilitate dental treatment. Objective: Purpose of this study was to evaluate and compare the effect of sedation by intranasal dexmedetomidine and oral combination drug midazolam–ketamine in a group of children with uncooperative behavior requiring dental treatment. Materials and Methods: This was a prospective, randomized, double-blind study that included patients 3–9 years old with American Society of Anesthesiologists-I status. About 36 children presenting early childhood caries were randomly assigned to one of three groups studied: Group MK received intranasal saline and oral midazolam (0.5 mg/kg) with ketamine (5 mg/kg) mixed in mango juice; Group DX received intranasal dexmedetomidine (1 μg/kg) and oral mango juice; and Group C received intranasal saline and oral mango juice. Patients' heart rate, blood pressure, and oxygen saturation were recorded before, during, and at the end of the procedure. Patients' behavior, sedation status, and wake up behavior were evaluated with modified observer assessment of alertness and sedation scale. Ease of treatment completion was evaluated according to Houpt scale. Results: Hemodynamic changes were statistically insignificant in Group MK and Group DX. About 75% patients in Group MK were successfully sedated as compared to 53.9% Group DX and none of the patients in Group C. Ease of treatment completion was better with Group MK as compared to Group DX and least with Group C. Around 50% patients in Group MK had postoperative complications. Conclusion: Oral midazolam–ketamine combination and intranasal dexmedetomidine evaluated in the present study can be used safely and effectively in uncooperative pediatric dental patients for producing conscious sedation.

Abstract
BACKGROUND Goal of premedication in pediatric anesthesia are relieving pre and postoperative anxiety, good parental separation, and smooth induction of anesthesia. Anxiety can produce aggressive reactions, increased distress, increased postoperative pain and postoperative agitation. The benzodiazepine, midazolam, is the most frequently used premedication in pediatric anesthesia. Midazolam has a number of beneficial effects when used as premedication in children: Sedation, fast onset, and limited duration of action. Though midazolam has a number of beneficial effects, it is far from an ideal premedicant having untoward side effects such as paradoxical reaction, respiratory depression, cognitive impairment, amnesia, and restlessness. Dexmedetomidine is a newer α-2-agonist, which can be used as premedicant. AIMS To compare the level of sedation, parental separation, mask acceptance, postoperative recovery of intranasal premedication with dexmedetomidine and dexmedetomidine-ketamine combination in pediatric patients. SETTINGS AND DESIGN Prospective randomized double-blind study. SUBJECTS AND METHODS After written informed consent from the patient's parents or legal guardian, 54 children of American Society of Anesthesiologists physical status I or II, aged between 1 and 6 years, scheduled to undergo elective minor surgery were enrolled. In group D patient received 1 μg/kg dexmedetomidine intranasally and in group DK received 1 μg/kg dexmedetomidine and 2 mg/kg ketamine intranasally. Patients were assessed every 10 min for the level of sedation, parenteral separation, heart rate, and oxygen saturation by an independent observer. Mask acceptance and postoperative agitation were noted using an appropriate scale. STATISTICAL ANALYSIS USED Pearson Chi-square analysis to determine differences between two groups with respect to separation anxiety and acceptance of the anesthesia mask. Percentages used to represent frequencies. The level of significance was set at P< 0.05. RESULTS Acceptable parenteral separation was achieved in 90% of patients 30 min after premedication. Sedation was acceptable in 80% of patients at induction. Good mask acceptance was seen in 60% of patients. The incidence of emergence agitation (EA) was 2%. None of the above parameters was statistically significant between the two groups. CONCLUSIONS Dexmedetomidine, as premedicant in children provides acceptable parenteral separation. However, mask acceptance in operation room is poor. Combination of dexmedetomidine and ketamine does not increase the success of premedication. Use of dexmedetomidine is associated with decreased EA.

Abstract
STUDY OBJECTIVE Midazolam has been found to have beneficial effects on anxiety in children in the preoperative setting. Prior studies have examined various postoperative behaviors of children, but little research has examined the effects of preoperative use of midazolam with postoperative sleep. The purpose of this investigation was to compare postoperative sleep in children as a function of preoperative sedative medication use. DESIGN This study was a 2-group randomized controlled trial. SETTING Participants were recruited from Yale-New Haven Children's Hospital. PATIENTS Participants included a convenience sample of 70 children between the ages of 3 to 12 years undergoing ambulatory tonsillectomy and adenoidectomy. INTERVENTIONS Children were randomly assigned to 1 of 2 groups: a control group who received preoperative acetaminophen only (n = 32) and an experimental group who received both acetaminophen and midazolam preoperatively (n = 38). MEASUREMENTS Parents completed measures of postoperative behavioral recovery and a subset of children wore actigraphs to examine objective sleep data. MAIN RESULTS Children who received midazolam experienced similar sleep changes compared to children in the control group. The actigraph data revealed that children who received midazolam were awake significantly less during the night compared to the control group (P= .01). CONCLUSION Children who received midazolam before surgery had similar postoperative sleep changes compared to children who did not receive midazolam. Further understanding of the postoperative behavioral effects of midazolam on children will help guide healthcare providers in their practice.

Abstract
Objective: In some medical circumstances, pediatric patients may need premedication for transferring to the operating room. In these situations, using intravenous premedication is preferred. We assessed the efficacy and safety of intravenous midazolam, intravenous ketamine, and combination of both to reduce the anxiety and improve behavior in children undergoing general anesthesia. Methods: In a double-blind randomized clinical trial, 90 pediatric patients aged 6 months to 6 years with American Society of Anesthesiologist grade I or II were enrolled. Before anesthesia, children were randomly divided into three groups to receive intravenous midazolam 0.1 mg/kg, or intravenous ketamine 1 mg/kg, or combination of half doses of both. Behavior types and sedation scores were recorded before premedication, after premedication, before anesthesia, and after anesthesia in the postanesthesia care unit. Anesthesia time, recovery duration, blood pressure, and heart rate were also recorded. For comparing distribution of behavior types and sedation scores among three groups, we used Kruskal–Wallis test, and for comparing mean and standard deviation of blood pressure and heart rates, we used analysis of variance. Findings: After premedication, children's behavior was significantly better in the combination group (P < 0.001). After anesthesia, behavior type was same among three groups (P = 0.421). Sedation scores among three groups were also different after premedication and the combination group was significantly more sedated than the other two groups (P < 0.001). Conclusion: Combination of 0.05 mg/kg of intravenous midazolam and 0.5 mg/kg of intravenous ketamine as premedication produced more deep sedation and more desirable behavior in children compared with each midazolam 0.1 mg/kg or ketamine 1 mg/kg.

Abstract
Background Temozolomide (TMZ) induces a G2/M cell cycle arrest and is used for treatment of paediatric tumours, especially neuroblastomas. Patients treated with TMZ frequently receive midazolam for sedation prior to surgery and other interventions. Previous studies suggested both cytoprotective and apoptosis-inducing properties of midazolam. Therefore, the impact of midazolam on TMZ-induced cytotoxicity was investigated in vitro. Methods Human neuroblastoma cells were incubated with midazolam alone, as a pretreatment prior to incubation with TMZ or a coincubation of both. Cell viability and proliferation was analysed (XTT and BrdU assay) after 24 h and flowcytometric cell cycle analysis was performed after 24 and 48 h. Results Midazolam alone increased cell viability at lower concentrations (2, 4, 8, 16 μM), whereas higher concentrations (128, 256, 512 μM) reduced cell viability. Pretreatment with midazolam 6 h prior to TMZ incubation reduced cytotoxic effects (IC25 1005 ± 197 μM; IC50 1676 ± 557 μM; P < 0.05) compared to incubation with TMZ alone (IC25 449 ± 304 μM; IC50 925 ± 196 μM) and reduced the antiproliferative effect of TMZ (1000 μM) by 43.9 % (P < 0.05). In contrast, cytotoxic effects of TMZ were increased (IC75 1175 ± 221 μM vs. 2764 ± 307 μM; P < 0.05) when midazolam pretreatment was followed by coincubation of midazolam and TMZ. Cell cycle analysis revealed increased fractions of cells in G2/M phase after TMZ treatment (100 μM; 48 h), irrespective of midazolam pretreatment. Conclusion Midazolam causes a hormetic dose–response relationship in human neuroblastoma cells. Pretreatment with midazolam reduces the cytotoxic and antiproliferative effects of TMZ without interfering with G2/M cell cycle arrest. In contrast, subsequent midazolam coincubation increases overall cytotoxicity.

Abstract
Background Triazolam has similar pharmacological properties as other benzodiazepines and is generally used as a sedative to treat insomnia. Alprazolam represents a possible alternative to midazolam for the premedication of surgical patients. The purpose of this study was to evaluate the anxiolytic, sedative, and amnestic properties of triazolam and alprazolam as pre-anesthetic medications. Methods Sixty adult patients were randomly allocated to receive oral triazolam 0.25 mg or alprazolam 0.5 mg one hour prior to surgery. A structured assessment interview was performed in the operating room (OR), the recovery room, and the ward. The levels of anxiety and sedation were assessed on a 7-point scale (0 = relaxation to 6 = very severe anxiety) and a 5-point scale (0 = alert to 4 = lack of responsiveness), respectively. The psychomotor performance was estimated using a digit symbol substitution test. As a memory test, we asked the patients the day after the surgery if they remembered being moved from the ward to the OR, and what object we had shown them in the OR. Results There were no significant differences between the groups with respect to anxiety and sedation. The postoperative interviews showed that 22.2% of the triazolam-treated patients experienced a loss of memory in the OR, against a 0% memory loss in the alprazolam-treated patients. In comparison with alprazolam 0.5 mg, triazolam 0.25 mg produced a higher incidence of amnesia without causing respiratory depression. Conclusions Oral triazolam 0.25 mg can be an effective preanesthetic medication for psychomotor performance.

Abstract
OBJECTIVE Ketamine administration is known to induce hemodynamic pressor response and psychomimetic effects which could be attenuated by appropriate premedication. The present study was designed to evaluate the effect of midazolam on hemodynamic stability and postoperative emergence phenomenon following ketamine anesthesia. METHODS This was a prospective observational study including 30 adult patients with American Society of Anesthesiologists physical grades I and II scheduled for elective short surgeries under ketamine anesthesia. Patients were premedicated with midazolam (0.02 mg/kg intravenously) before the ketamine induction (1 mg/kg intravenously). Demographic data and hemodynamic variables were observed during the perioperative period. Pain score by visual analog scale score and psychomimetic effects were recorded postoperatively. FINDINGS The mean ± standard deviation of heart rate, systolic blood pressure, diastolic blood pressure, and respiratory rate were decreased postoperatively (85.3 ± 11.4, 120.7 ± 8.2, 79.2 ± 5.5, 13.5 ± 1.8, respectively) compared to intraoperative period (88.53 ± 14.1, 123.83 ± 13.8, 83 ± 9.1, 14.13 ± 2.0, respectively). There was statistically significant decrease in systolic (P = 0.03) and diastolic (P = 0.002) blood pressure, but not with heart rate and respiratory rate. Eighty percent of patients had no pain at ½ hour and 1 hour, while this increased to 90% at 2 hours postoperatively. Mild emergence delirium was noted in 13.3% and 16.7% at ½ hour and 1 hour, respectively, which decreased to 13.3% at 2 hours. Dreams were noticed in 20%, 27% and 10% of patients at ½ hour, 1 and 2 hours after surgery, respectively. CONCLUSION Midazolam premedication in ketamine anesthesia effectively attenuated the hemodynamic pressor response and postoperative emergence phenomenon. Hence, the combination of midazolam with ketamine can be safely used for short surgical painful procedures in adults.

Abstract
Midazolam is the most commonly used premedication in children. It has been shown to be more effective than parental presence or placebo in reducing anxiety and improving compliance at induction of anesthesia. Clonidine, an a2 agonist, has been suggested as an alternative. Dexmedetomidine is a more a2 selective drug with more favorable pharmacokinetic properties than clonidine.

Abstract
Midazolam is a short-acting benzodiazepine that is in wide clinical use as an anxiolytic, sedative, hypnotic, and anticonvulsant. Midazolam has been shown to inhibit ion channels, including calcium and potassium channels. So far, the effects of midazolam on cardiac human ether-à-go-go-related gene (hERG) channels have not been analyzed. The inhibitory effects of midazolam on heterologously expressed hERG channels were analyzed in Xenopus oocytes using the double-electrode voltage clamp technique. We found that midazolam inhibits hERG channels in a concentration-dependent manner, yielding an IC50 of 170 μM in Xenopus oocytes. When analyzed in a HEK 293 cell line using the patch-clamp technique, the IC50 was 13.6 μM. Midazolam resulted in a small negative shift of the activation curve of hERG channels. However, steady-state inactivation was not significantly affected. We further show that inhibition is state-dependent, occurring within the open and inactivated but not in the closed state. There was no frequency dependence of block. Using the hERG pore mutants F656A and Y652A we provide evidence that midazolam uses a classical binding site within the channel pore. Analyzing the subacute effects of midazolam on hERG channel trafficking, we further found that midazolam does not affect channel surface expression. Taken together, we show that the anesthetic midazolam is a low-affinity inhibitor of cardiac hERG channels without additional effects on channel surface expression. These data add to the current understanding of the pharmacological profile of the anesthetic midazolam.

Abstract
BACKGROUND Dexmedetomidine-induced bradycardia or hypotension has recently attracted considerable attention because of potentially grave consequences, including sinus arrest and refractory cardiogenic shock. A route other than intravenous injection or a low dose may help minimize cardiovascular risks associated with dexmedetomidine. However, few studies have addressed the clinical effects of low-dose intramuscular dexmedetomidine as premedication. MATERIAL AND METHODS Forty American Society of Anesthesiologists physical status I adult patients undergoing suspension laryngoscopic surgery were randomized to receive intramuscular dexmedetomidine (1 µg·kg-1) or midazolam (0.02 mg·kg-1) 30 minutes prior to anaesthesia induction. The sedative, hemodynamic, and adjuvant anaesthetic effects of both premedications were assessed. RESULTS The levels of sedation (Observer's Assessment of Alertness/Sedation scales) and anxiety (visual analog score) at pre-induction, and the times to eye-opening and extubation, were not different between the groups. The heart rate response following tracheal intubation and extubation, and mean arterial pressure responses after extubation, were attenuated in the dexmedetomidine group compared to the midazolam group. No bradycardia or hypotension was noted in any patients. Propofol target concentrations at intubation and at start and completion of surgery were decreased in the dexmedetomidine group, whereas no difference in respective remifentanil levels was detected. CONCLUSIONS This study provides further evidence that dexmedetomidine premedication in low dose (1 μg·kg-1) by intramuscular route can induce preoperative sedation and adjuvant anaesthetic effects without clinically significant bradycardia or hypotension.

Efficacy of acupuncture in reducing preoperative anxiety: a meta-analysis. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:850367. [PMID: 25254059 PMCID: PMC4165564 DOI: 10.1155/2014/850367] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2014] [Revised: 07/11/2014] [Accepted: 07/11/2014] [Indexed: 11/18/2022]
Abstract
Background. Acupuncture has been shown to reduce preoperative anxiety in several previous randomized controlled trials (RCTs). In order to assess the preoperative anxiolytic efficacy of acupuncture therapy, this study conducted a meta-analysis of an array of appropriate studies. Methods. Four electronic databases (MEDLINE, EMBASE, CENTRAL, and CINAHL) were searched up to February 2014. In the meta-analysis data were included from RCT studies in which groups receiving preoperative acupuncture treatment were compared with control groups receiving a placebo for anxiety. Results. Fourteen publications (N = 1,034) were included. Six publications, using the State-Trait Anxiety Inventory-State (STAI-S), reported that acupuncture interventions led to greater reductions in preoperative anxiety relative to sham acupuncture (mean difference = 5.63, P < .00001, 95% CI [4.14, 7.11]). Further eight publications, employing visual analogue scales (VAS), also indicated significant differences in preoperative anxiety amelioration between acupuncture and sham acupuncture (mean difference = 19.23, P < .00001, 95% CI [16.34, 22.12]). Conclusions. Acupuncture therapy aiming at reducing preoperative anxiety has a statistically significant effect relative to placebo or nontreatment conditions. Well-designed and rigorous studies that employ large sample sizes are necessary to corroborate this finding.

Abstract
BACKGROUND Most patients are anxious before surgery. The level of preoperative anxiety depends on several factors and merits an objective evaluation. The Amsterdam Preoperative Anxiety and Information Scale (APAIS) is a self-report questionnaire comprising six questions that have been developed and validated to evaluate the preoperative anxiety of patients. This global index assesses three separate areas: anxiety about anaesthesia, anxiety about surgery, and the desire for information. The purpose of this study was to translate the APAIS into French and to evaluate the psychometric properties of the French version of the APAIS. METHODS The process consisted of two steps. The first step involved the production of a French version of the APAIS that was semantically equivalent to the original version. In the second step, we evaluated the psychometric properties of the French version, including the internal consistency and reliability, the differential item functioning, and the external validity. Participants older than 18, undergoing elective surgery (except obstetric), able to understand and read French, and able to complete a self-report questionnaire were eligible for inclusion in the study. A forward-backward translation was performed. The psychometric evaluation covered three domains: internal validity, external validity, and acceptability. Within 4-48 h after surgery, the patients were asked to complete the "Evaluation du Vécu de l'ANesthésie" questionnaire" (EVAN) questionnaire, which is a validated, multi-dimensional questionnaire that assesses the patient's experiences in the perioperative period. RESULTS A database with 175 patients was created. The principal component factor analysis revealed the same three-dimensional structure as the original scale. The confirmatory factor analysis showed a strong fit with a root mean square error of approximation of 0.069 and a comparative fit index of 1.00. The amount of differential item functioning (DIF) between the subgroups of patients (i.e., based on age, gender, type of anaesthesia or surgery, premedication, ASA physical status, and ambulatory course) was low. The APAIS was strongly correlated with the dimensions of the EVAN. Each dimension had a low proportion of missing values (ranging from 0.6 to 2.9%), which indicates good acceptability of the questionnaire. CONCLUSIONS The French version of the APAIS is valid and reliable. The availability of this tool enables the evaluation of anxiety in French patients undergoing anaesthesia.

Abstract
Background: To compare oral midazolam (0.5 mg/kg) with oral butorphanol (0.2 mg/kg) as a premedication in 60 pediatric patients with regards to sedation, anxiolysis, rescue analgesic requirement, and recovery profile. Materials and Methods: In a double blinded study design, 60 pediatric patients belonging to ASA class I and II between the age group of 2–12 years scheduled for elective surgery were randomized to receive either oral midazolam (group I) or oral butorphanol (group II) 30 min before induction of anesthesia. The children were evaluated for levels of sedation and anxiety at the time of separation from the parents, venepuncture, and at the time of facemask application for induction of anesthesia. Rescue analgesic requirement, postoperative recovery, and complications were also recorded. Results: Butorphanol had better sedation potential than oral midazolam with comparable anxiolysis at the time of separation of children from their parents. Midazolam proved to be a better anxiolytic during venepuncture and facemask application. Butorphanol reduced need for supplemental analgesics perioperatively without an increase in side effects such as nausea, vomiting, or unpleasant postoperative recovery. Conclusion: Oral butorphanol is a better premedication than midazolam in children in view of its excellent sedative and analgesic properties. It does not increase side effects significantly.

Abstract
GABA is the major inhibitory neurotransmitter in the central nervous system (CNS). The type A GABA receptor (GABA(A)R) system is the primary pharmacological target for many drugs used in clinical anesthesia. The α1, β2, and γ2 subunit-containing GABA(A)Rs located in the various parts of CNS are thought to be involved in versatile effects caused by inhaled anesthetics and classic benzodiazepines (BZD), both of which are widely used in clinical anesthesiology. During the past decade, the emergence of tonic inhibitory conductance in extrasynaptic GABA(A)Rs has coincided with evidence showing that these receptors are highly sensitive to the sedatives and hypnotics used in anesthesia. Anesthetic enhancement of tonic GABAergic inhibition seems to be preferentially increased in regions shown to be important in controlling memory, awareness, and sleep. This review focuses on the physiology of the GABA(A)Rs and the pharmacological properties of clinically used BZDs. Although classic BZDs are widely used in anesthesiological practice, there is a constant need for new drugs with more favorable pharmacokinetic and pharmacodynamic effects and fewer side effects. New hypnotics are currently developed, and promising results for one of these, the GABA(A)R agonist remimazolam, have recently been published.

Abstract
BACKGROUND Preoperative anxiety frequently causes resistance to mask application and prolongs induction. Anesthesia masks resembling popular heroes or toys was used to deal with this problem. An anesthesia mask given on a preoperative visit to play with at home, may aid to establish a familiarity with the mask and alleviate mask fear, possibly making a gaseous induction more acceptable. METHODS After approval of the ethical committee, 50 children were randomly assigned into two groups. Both groups received conventional verbal information about the anesthetists, materials and equipment to be used for the procedure, description of gaseous induction via mask and transportation to the operating room. Additionally transparent anesthesia masks were given to children in the mask group after conventional verbal information. Both groups were premedicated with 0.3 mg.kg(-1) midazolam. Anxiety was assessed during separation from parents and induction of anesthesia by a modified Yale Preoperative Anxiety Scale. Mask acceptance quality and total mask time (TMT; time between the introduction of mask anesthesia and the loss of lid reflex) were also determined. RESULTS Anxiety levels in the informed group were statistically higher than in the mask group during induction of anesthesia (26 +/- 1.8 vs 30 +/- 2.9, P < 0.05). Mask acceptance quality was better in the mask group than in the informed group (IG). TMTs were 5.1 +/- 1.3 and 7 +/- 0.9 min in the mask group and in the IG, respectively. CONCLUSIONS Playing with an anesthesia mask given during a preanesthesia visit relieved anxiety, improved mask acceptance quality and shortened the induction period. We believe that this type of premedication would be feasible in gaseous induction of anesthesia in children.

Abstract
BACKGROUND The effect of two premedication regimes with different benzodiazepines on anxiety, hemodynamic data, sympatho-adrenal activity, and bispectral index (BIS) was evaluated during the variable time period prior to induction of anesthesia. PATIENTS AND METHODS This prospective, double-blind study was performed with 50 ASA class I and II patients. Patients were randomized either to group I: evenings 22.00 hours 50 mg chlorazepate dipotassium (CD), mornings 07.00 hours 25 mg CD, placebo 30 min prior to anesthesia (on demand) or group II: evenings 50 mg CD, mornings placebo, 7.5 mg midazolam on demand. RESULTS In group I the BIS dropped after administration of 25 mg CD and was significantly lower at 08.00, 09.00 and 10.00 hours compared to baseline (mean+/-SD; 90+/-5, 87+/-7 and 87+/-7, respectively vs. 95+/-4; p<0.05), whereas the BIS of group II did not decrease significantly. Both groups did not differ significantly with respect to all variables obtained throughout the study period. CONCLUSION We conclude that 50 mg CD the evening before surgery prevented an increase of anxiety and sympatho-adrenal activity in both groups and might therefore be sufficient as premedication. Fixed time application of 25 mg CD at 07.00 hours or 7.5 mg midazolam 30 min prior to anesthesia did not further affect these variables preoperatively.

Abstract
Clonidine is experiencing increasing use in the pediatric population as a sedative and analgesic because of its central alpha2-adrenergic agonism. We report three cases of preoperative use of intranasal clonidine in pediatric patients, all for different indications. One patient was treated for preoperative agitation and hallucinations associated with oral midazolam. One patient was given clonidine as a premedicant. The third patient was treated for preoperative agitation and hypertension. All three patients had subjective resolution of indicated symptoms and none experienced adverse outcomes.

Abstract
BACKGROUND Pre-anesthetic anxiety and emergence agitation are major challenges for anesthesiologists in pediatric anesthesia. Thus, sedative premedication and parental presence during induction of anesthesia (PPIA) are used to treat pre-anesthetic anxiety in children. The aim of the present study was to test if a combination of mother presence and midazolam premedication is effective for improving emergence condition in children undergoing general anesthesia. METHODS Sixty children were allocated to one of three groups: a sedative group (0.5 mg/kg oral midazolam), a PPIA group or a sedative and PPIA group. When anesthesia was induced with 7% sevoflurane in 100% oxygen, qualities of mask induction were rated. Anesthesia was maintained with sevoflurane (1.5-2.5%) in 60% oxygen and intravenous fentanyl 4 microg/kg. During emergence from anesthesia, the score of the child's emergence behavior was rated. RESULTS The children in the midazolam group showed a better quality of mask induction compared with those in the PPIA group, the addition of parental presence to oral midazolam did not provide additional improvement of mask induction. In contrast, the children in the midazolam + PPIA group were less agitated than those in the other groups at emergence from anesthesia. CONCLUSION Parental presence during induction of anesthesia enhanced the effect of oral midazolam on emergence behavior of children undergoing general anesthesia.

Abstract
OBJECTIVE Findings from published studies suggest that the postoperative recovery process is more painful, slower, and more complicated in adult patients who had high levels of preoperative anxiety. To date, no similar investigation has ever been conducted in young children. METHODS We recruited 241 children aged 5 to 12 years scheduled to undergo elective outpatient tonsillectomy and adenoidectomy. Before surgery, we assessed child and parental situational anxiety and temperament. After surgery, all subjects were admitted to a research unit in which postoperative pain and analgesic consumption were assessed every 3 hours. After 24 hours in the hospital, children were discharged and followed up at home for the next 14 days. Pain management at home was standardized. RESULTS Parental assessment of pain in their child showed that anxious children experienced significantly more pain both during the hospital stay and over the first 3 days at home. During home recovery, anxious children also consumed, on average, significantly more codeine and acetaminophen compared with the children who were not anxious. Anxious children also had a higher incidence of emergence delirium compared with the children who were not anxious (9.7% vs 1.5%) and had a higher incidence of postoperative anxiety and sleep problems. CONCLUSIONS Preoperative anxiety in young children undergoing surgery is associated with a more painful postoperative recovery and a higher incidence of sleep and other problems.

Abstract
BACKGROUND Oral Transmucosal ketamine (lollipop) has been shown to be an effective, harmless preoperative medication for children. However, its efficacy was not compared with commonly used premedication drugs. We, therefore, compared the efficacy of oral transmucosal ketamine with oral midazolam for premedication in children. METHODS Fifty-five children (2-6 years of age) were randomized to receive orally either a lollipop containing 50 mg of ketamine (the group K; n = 27) or syrup containing 0.5 mg.kg(-1) of midazolam (the group M; n = 28) before minor surgery. A five points-sedation score (1 = asleep to 5 = agitated; scores 2 and 3 were defined as 'effective') on arrival in the operating room and a three points-acceptance score of separation from the parents and a three points-mask cooperation score at induction of anesthesia (1 = easy to 3 = markedly resistant; score 3 was defined as 'poor') were used. RESULTS Sedation scores in group K were significantly higher than those in group M (P = 0.012), and the incidence of 'effective' in sedation was significantly lower in group K than in group M (P = 0.036). The incidence of 'poor' at separation from the parents and for mask cooperation was significantly higher in group K than in group M (P = 0.017, P = 0.019, respectively). CONCLUSION These results indicate that a relatively low dose of oral transmucosal ketamine premedication provides no benefits over oral midazolam in children.

Abstract
Intramuscular injections are still part of routine care in the treatment of children. Vaccines, premedications and analgesics are administered by this route. The pain associated with an intramuscular injection is severe, the risk of complications is increased, and pharmacodynamics and pharmacokinetics are unpredictable. In many cases, equivalent alternatives of rectal, oral or intranasal routes of administering pharmacologic agents exist. Intramuscular injection of analgesics and premedications to children are-except in case of emergencies-obsolete. This demand corresponds to the guidelines of the World Health Organization (WHO) and the International Association for the Study of Pain (IASP).

BACKGROUND Oral premedication with midazolam and ketamine is widely used in pediatric anesthesia to reduce emotional trauma and ensure smooth induction. However, various dosing regimens when used alone or in combination have variable efficacy and side effect profile. The aim of our study was to investigate and compare the efficacy of oral midazolam alone with a low-dose combination of oral midazolam and ketamine. METHODS We performed a prospective randomized double-blind study in 100 children who were randomly allocated into two groups. Group M received 0.5 mg.kg(-1) oral midazolam and group MK received 0.25 mg.kg(-1) oral midazolam with 2.5 mg.kg(-1) oral ketamine. The preoperative sedation score, ease of parental separation and ease of mask acceptance were evaluated on a 4-point scale. The time to recovery from anesthesia and to achieve satisfactory Aldrete score was also noted. RESULTS Uniform and acceptable sedation scores were seen in both the groups (group M 95.9%; group MK 97.96%), without any serious side effects. However, the combination offered significantly more children in an awake, calm and quiet state, who were easily separated from their parents (73.46% in MK vs 41% in group M). The induction scores were comparable between the groups. The recovery room characteristics and time to achieve satisfactory Aldrete score were also comparable between the two groups. CONCLUSIONS Oral midazolam alone and a combination of midazolam with ketamine provide equally effective anxiolysis and separation characteristics. However, the combination provided more children in an awake, calm and quiet state who could be separated easily from parents.

Abstract
BACKGROUND The main objectives of premedication in children are to facilitate the separation from the parents, to reduce preoperative anxiety, to smooth the induction of anesthesia and to lower the risk of postoperative behavioral disorders. The most common technique is sedative premedication with midazolam. Hypnosis enables a state of relaxation to be achieved and has never been evaluated as a premedication technique. The aim of the present study was to evaluate the efficacy of hypnosis on anxiety and perioperative behavioral disorders versus midazolam. METHODS Fifty children from 2 to 11 years of age were randomized into two groups: group H received hypnosis as premedication; group M were given 0.5 mg x kg(-1) midazolam orally, 30 min before surgery. Preoperative anxiety was evaluated using the Modified Yale Preoperative Anxiety Scale (mYPAS) score when arriving in the department (T1), when entering the operating room (T2), and when fitting the facemask (T3). Postoperative behavioral disorders were evaluated using the Posthospitalization Behavioral Questionnaire (PHBQ) at days 1, 7 and 14. RESULTS The two groups showed no significant difference preoperatively with the PHBQ: (M) 21 (17-25) vs (H) 20 (8-25) and mYPAS score: (M) 28 (23-75) vs (H) 23 (23-78). The number of anxious children was less during induction of anesthesia in the hypnosis group (T3: 39% vs 68%) (P < 0.05). Postoperatively, hypnosis reduced the frequency of behavior disorders approximately by half on day 1 (30% vs 62%) and day 7 (26% vs 59%). CONCLUSIONS Hypnosis seems effective as premedication in children scheduled for surgery. It alleviates preoperative anxiety, especially during induction of anesthesia and reduces behavioral disorders during the first postoperative week.

Abstract
Up to 60% of all children undergoing anesthesia and surgery experience significant anxiety and distress during the perioperative period. Currently, both behavioral interventions such as parental presence during induction of anesthesia and pharmacological interventions such as sedative premedication are used to treat this clinical phenomenon. In this review, we examine the effectiveness of these interventions on clinically relevant perioperative outcomes.
