Behavioral problems in children contribute significantly to non-compliance and lack of cooperation with dentists.This study aimed to assess the impact of parenting styles on the success of conscious sedation with midazolam in uncooperative children aged 4 to 6 years.  

This short-term longitudinal study included ninety-six children aged 4-6 years who were classified as uncooperative according to the Frankl Behavior Rating Scale (Frankl I, II), requiring pulp treatment and Stainless-Steel Crown (SSC) restoration. Midazolam was orally administered at 0.25 mg/kg. Parents completed the Parental Stress Dental Questionnaire (PSDQ), Strengths and Difficulties Questionnaire (SDQ), and Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). Treatment began at least thirty minutes post-drug administration. Vital signs were monitored using a pulse oximeter. Sedation effectiveness was assessed with the Houpt scale at local anesthesia injection (T0), cavity preparation (T1), restoration (T2), and treatment conclusion (T3). Statistical analysis used Kruskal-Wallis and Mann-Whitney U tests (P < 0.05).  

Most parents (69, 71.9%) had an authoritative parenting style, while 10 (10.4%) were authoritarian, and 17 (17.7%) were permissive. Authoritative parenting is associated significantly with sedation success (P = 0.001) and reduced dental fear (P = 0.008). Conversely, authoritarian (P = 0.031) and permissive (P = 0.001) parenting styles are associated with sedation failure. Authoritarian parenting is associated positively with increased dental fear (P = 0.001). No significant association was found between permissive parenting style and dental fear (P > 0.05). No significant association existed between behavioral problems and parenting styles (P > 0.05). There was no significant association observed between permissive parenting style and dental fear (P = 0.279). Similarly, no significant associations were found between behavioral problems and specific parenting styles: authoritative (P = 0.625), authoritarian (P = 0.050), and permissive (P = 0.522).  

Understanding parenting styles aids in predicting conscious sedation success with midazolam and assisting in managing uncooperative children during dental procedures.

There is no agreement on the route of administration and the drug of choice for providing adequate sedation for pediatric invasive procedures.

We compared the utility, safety, and sedation effects of intranasal midazolam and oral ketamine.

This double-blind clinical trial was performed on 100 children aged 2 to 14 years who were candidates for upper gastrointestinal (GI) endoscopy. Patients were randomly assigned to two groups: ketamine (4 mg/kg orally) and midazolam (0.1 mg/ kg intranasal). Sedation score, fear levels, children’s behavior at the time of separation from parents, and vital signs were recorded.

Higher systolic blood pressure was seen in children who received ketamine (P=0.012) and lower arterial oxygen saturation in the midazolam group (P=0.023). Also, the level of sedation showed no significant difference between the groups.

Based on the results, administering oral ketamine or intranasal midazolam before endoscopy induced a similar sedation score in children. Also, both methods could be safe and non-invasive modalities for sedation.

Amelogenesis imperfecta (AI) is a rare hereditary developmental disease that has a significant effect on the enamel structure. Both primary and permanent dentition could be affected by this condition. The pivotal characteristics are loss of the tooth structure, wear of enamel, and exposed dentinal areas at the occlusal surface of posterior teeth. AI may be inherited in autosomal dominant, autosomal recessive, or X‐linked types. Treatments of AI cases should be initiated in childhood and continue into adolescence. Considering that AI is a rare and heterogeneous condition, the dental team faces various difficulties regarding choosing the appropriate treatment plan. The oral rehabilitation of patients with AI is a challenging condition that needs a multidisciplinary approach. Many treatment options have been reported for solving cosmetic and restorative problems in AI cases. The conservative treatment plan in this hypoplastic-hypomature AI case included esthetic rehabilitation with a sequential method, innovative non-invasive pulp-therapy methods, and dental restorations under oral sedation. The written consent for the treatments was obtained after consultation with the child and his parents.

Procedural sedation (PS) plays an important role in facilitating emergency procedures. Dexmedetomidine is an alpha-adrenergic agonist which can play a role in this issue. This study aimed to systematically review the literature about the role of dexmedetomidine in PS in the emergency department (ED).

In this study, several databases, namely PubMed, Embase, Ovid, ProQuest, Scopus, Web of Science, and Cochrane Library, were searched since 1999 up to November 30, 2020. The inclusion criteria in this study were randomized clinical trials performed on ED patients using dexmedetomidine for PS and articles only in the English language. The exclusion criteria were the studies that were not clinical trials or were not performed in the ED, low-quality studies or animal studies.

A total of 473 articles were identified in this study. Five studies fulfilled the inclusion and exclusion criteria. Three articles studied the adult population. One study used dexmedetomidine in an intranasal way, and one study used an intramuscular route for drug administration.

Although the reviewed studies reported dexmedetomidine as a safe and effective agent for PS, there are not sufficient data on this issue. Therefore, it is required to perform further studies to a draw firmer conclusion.

Brugada syndrome (BrS), a type of sudden arrhythmic unexpected death syndrome (SADS), is characterized by specific electrocardiogram (ECG) changes, a structurally normal heart, and susceptibility to life-threatening ventricular arrhythmias. General anesthesia (GA) is usually used for major surgery in patients with BrS due to concerns that some local anesthetic agents may precipitate critical arrhythmias. The majority of ophthalmic surgeries are successfully carried out under regional anesthesia (RA). The literature does not address the use of ophthalmic RA in patients with BrS except one report of peribulbar block for glaucoma surgery. This clinical case report and the liertature review suggests that for BrS patients presenting for vitreoretinal surgery, a sub-tenon block, with or without sedation may safely be used as a primary anaethestic technique.

Sedation has a beneficial impact on patient’s tolerance to the endoscopic procedure. Conscious sedation is the anesthetic techniques of choice for endoscopic procedure. Conscious sedation for endoscopic procedure could be with one drug or a combination of drugs. There have been broad variations in sedation procedure between different countries, and even between different units within the same country. All drugs which depress the central nervous system have the ability to produce respiratory or cardiovascular complications. Endoscopy has a recorded mortality of 1 in 2000 and a morbidity rate of 1 in 200. These sedation techniques have their effects on patients.The main goal of this study is to describe the effects of conscious sedation on patients' outcome for endoscopic procedure.

The design for this study was a review of literature in the medical databases of PubMed, Scopus, Embase, Cochrane and hand search journals from conferences in English. All studies that evaluated the use of CS for endoscopic procedure were included.

The results showed that the pain level of the patient (visual analogue scale) was substantially positive when conscious sedation was used. Conscious sedation, however is a lightly sedated patient who is conscious, amnesic, co-operative on demand and free from fear and anxiety. It is often used during endoscopic procedures to minimize discomfort and relax the patients. The intraoperative hypotension has also been extreme in some medications relative to others.

The study revealed that CS is reliable and well tolerated anesthetic technique for endoscopic procedures, and is a better option for elective endoscopic procedures CS benefits for endoscopisit and patient outcome is superior to GA such as; short recovery times, less analgesia requirement, comfortable for patient which in turn, leads to faster induction, faster endoscopy, faster discharge, and faster turnaround time. Patients are usually willing to go home after a couple of hours. Rapid recovery is a benefit not only for patients, but also for hospital and day surgery departments. This increases the overall performance of the endoscopy unit.

Ketamine is a commonly used medicine for reducing pain and stress in patients, including children in emergency department (ED). The intravenous (IV) injection of ketamine is gold standard though difficult in children, but other routes are also possible. 

This study was conducted to compare the effects of the submucosal at different doses versus IV injections of ketamine on sedation with proper consciousness in children candidates for diagnostic-therapeutic procedures in ED. 

This randomized clinical trial was conducted with 4 groups; groups 1, 2 and 3 respectively received 4, 3 and 2 mg/kg of submucosal ketamine and group four 1.5 mg/kg of IV ketamine. Eligible subjects selected from 46 patients of children’s age as the candidates for subcutaneous wound healing were randomly assigned to the four groups and followed up 5, 10, 15 and 30 minutes after the injection. The Ramsay score was obtained by measuring the heart rate, the breathing rate, the time to start affecting and duration of the effect. The data were ultimately analyzed in SPSS and Excel. 

The baseline data were matched and confounding variables eliminated included age, gender, weight and hemodynamics. Compared to other doses of submucosal ketamine, 4 mg/kg was found to exert its effect the fastest (4.08±1.01 minutes) (p<0.05) and for the longest duration (23.09±1.12 minutes) (p<0.05). The Ramsay score in groups 1 and 4, i.e. 5.9, was significantly higher than that in groups 2 and 3 (p<0.05). 

The results showed that 4 mg/kg and 3 mg/kg of submucosal ketamine are appropriate alternatives to IV ketamine. Although the time to start affecting was shorter in the intravenous group compared to in the other groups, the duration of the effect was the longest with 4 mg/kg of submucosal ketamine. Surgeon satisfaction scores were found to be very good and not significantly different between groups 1, 2 and 4. Vomiting was also prevalent with no significant differences between the four groups.

Aspiration of gastric contents is one of the most important complications during procedural sedation and analgesia (PSA). It seems that gastric ultrasonography could be a suitable tool for qualitative and quantitative measurement of gastric contents before PSA. 

In the present study, efforts were made to assess the correlation between ultrasonographic gastric antral area and incidence of vomiting in patients underwent PSA. 

In the present cross-sectional study, using a convex 4MHz probe in supine position, ultrasonographic evaluation of gastric antral area was done for 100 participants in need of PSA. The evaluations were done from the outer layer of the gastric wall and 3 images were recorded between peristaltic contractions. Finally, the rate of vomiting incidence in patients were recorded and compared with the results of patients’ ultrasonography. 

The findings showed that anteroposterior diameter (AP), craniocaudal diameter (CC), and cross-sectional area (CSA) had a statistically significant correlation with incidence of vomiting in patients (p ≤ 0.0001). The odds ratio of these variables show that increase in antral diameter leads to increase incidence of vomiting. Based on these findings, 1 unit rise in AP increases the odds of vomiting by 7.45 times, 1 unit increase in CC increases the odds by 7.20 times, and finally, 1 unit increase in CSA increases the odds of vomiting by 1.32 times. 

Gastric antrum ultrasonography can be used as a proper diagnostic tool for assessing the risk of vomiting in patients undergoing PSA.

The purpose of this study was to compare the effectiveness and side effects of diazepam and midazolam administration for conscious sedation in subjects who undergoing cataract surgery.

A total of 79 patients undergoing cataract surgery under topical anesthesia with conscious sedation were prospectively reviewed. Our subjects were randomly divided to two groups. The first group comprised of 38 cases receiving 0.05 mg/kg diazepam slow intravenously (diazepam group) and the second group comprised of 41 cases receiving 0.01 mg/kg midazolam intravenously (midazolam group). Intraoperative variables such as systolic and diastolic arterial pressure, heart rate, respiratory rate and blood oxygen saturation were recorded immediately before sedation, 5, 10 and 15 minutes after diazepam or midazolam administration. All patients were contacted 24 hours after the operation for any early postoperative complications.

The variability of systolic and diastolic blood pressure at 5, 10 and 15 minutes after sedation were statistically significantly higher in midazolam group compared to diazepam group. Six patients developed episodes of apnea during operation, two patients in diazepam and four patients in midazolam group. The surgeons’ satisfaction was more in diazepam group but not statistically significant. Need for additional dose of benzodiazepine was more in the midazolam group. Drowsiness and functional impairment during 24 hours after surgery were not significantly different between the two groups.

Diazepam produces better perioperative hemodynamic profile, level of sedation and surgeon’s satisfaction and less occurrence of apnea compared to midazolam group in patients who underwent cataract surgery.

Currently, using various combinations of narcotic and analgesic drugs has received attention for induction of sedation and analgesia due to their synergy in controlling pain and anxiety. The present study was designed with the aim of comparing dexmedetomidine-fentanyl combination with midazolam-fentanyl in this regard. In this randomized clinical trial, patients diagnosed with distal radius fracture who had visited the emergency department (ED) were allocated to either the group receiving the combination of fentanyl-midazolam or the one receiving dexmedetomidine-fentanyl for procedural sedation and analgesia (PSA) and were compared regarding analgesic characteristics, time to recovery and side effects. 80 patients with the mean age of 42.08 ± 12.17 (18 - 60) years were randomly allocated to 2 groups of 40 (83.80% male). The 2 groups did not have a significant difference regarding baseline characteristics as well as pain severity. Mean pain score at the time of procedure was 3.47 ± 1.37 in dexmedetomidine and 2.85 ± 1.05 in midazolam group (p = 0.025). In addition, time to recovery in dexmedetomidine and midazolam groups was 6.60 ± 1.86 minutes and 12.70 ± 1.70 minutes, respectively (p < 0.001). Out of the 9 patients who experienced treatment failure, 8 (88.90%) patients were in dexmedetomidine group and 1 (11.10%) was in midazolam group (p = 0.029). Absolute risk increase rate of treatment failure in case of using dexmedetomidine instead of midazolam was 17.50% (95%CI: 4.19 – 30.81) and number needed to harm was 6.00 (95% CI: 3.20 – 23.80). Although the combination of dexmedetomidine-fentanyl had a shorter time to recovery compared to midazolam-fentanyl for induction of sedation and analgesia, the treatment failure rate in case of using dexmedetomidine with 1 µg/kg increased 17.5% and about 1 out of each 6 patients needed a rescue dose.

Finding a fast-acting compound with minimal side-effects to induce a safe and efficient analgesia with short or medium duration of action is of great interest in the emergency department. The present study has been designed with the aim of comparing the effect of midazolam + fentanyl + lidocaine combination with midazolam + fentanyl + placebo in pain management of anterior shoulder dislocation reduction. The present two-arm parallel double-blind randomized controlled trial was performed on patients who presented to emergency department with anterior shoulder dislocation. Patients were randomly allocated to the 2 treatment groups of midazolam + fentanyl + placebo (double-drug group) and midazolam + fentanyl + intravenous (IV) lidocaine (triple-drug group). Then outcomes such as treatment success rate and side-effects following prescription of drugs were compared between the 2 groups. 100 patients were included in the present study (50 patients in each group; mean age of the studied patients 27.3±8.9 years; 93.0% male). Using the double-drug regimen led to 35 (70%) cases of complete analgesia, while this rate in the triple-drug group was 41 (82%) cases (p=0.16). The calculated number needed to treat was 9 cases. This means that about one in every 9 patients in treatment arm will benefit from the treatment. The most important side-effects observed included dysrhythmia (1 patient in double drug and 1 patient in triple-drug group), apnea (2 patients in each group) and SPO2<90% (2 patients in triple-drug group) (p=0.78). Number needed to harm was 25 cases. In other words, for each 25 patients treated with the triple drug regimen, 1 case of SPO2<90% is observed. Findings of the present study showed that adding IV lidocaine to IV midazolam + fentanyl drug combination does not provide additional analgesia in sedation for anterior shoulder reduction.

This study compared the safety and efficacy of nitrous oxide (N2O)/midazolam and N2O/promethazine for dental treatment of uncooperative children. In this randomized, cross‑over, clinical trial investigation Eighteen healthy uncooperative children with a pair of similar teeth requiring the same treatment were included.Combination of N2O/midazolam was given in one visit, where N2O/promethazine was administrated in the other appointment for each patient in a cross‑over manner. Oxygen saturation and heart rate as well as behavior parameters according to Houpt behavior scales were recorded. Postoperatively, patients’ anxiety and parents’ satisfaction were assessed by visual analog score and
a questionnaire, respectively. Data were analyzed using Wilcoxon’ s signed rank test and Paired t‑tests with a P value set at 0.05. Physiologic parameters were within normal limit in both groups. Children in midazolam group were significantly deeper sedated compared to other groups. In the first phase, children
sedated with midazolam behaved superiorly in comparison to promethazine, while there was no difference at the final phase of the treatment between the two groups. Both of the drug combinations resulted in acceptable, efficient, and safe sedation outcomes.

This study aimed to evaluate the effect of oral melatonin and oral midazolam as premedication for intravenous (IV) sedation of pediatric dental patients. This crossover, double-blind randomized clinical trial was conducted on 23 uncooperative 2-6-year-olds with definitely negative behaviors according to the Frankl's scale. Each child served as their own control. The children were randomly divided into two groups: group I received 0.5mg/kg of oral melatonin one hour before IV sedation, while group II received 0.5mg/kg of oral midazolam 30 minutes before IV sedation on their first visit. Every child received the other premedication on their second visit. The degree of sedation was judged according to the Houpt scale. Physiologic parameters including blood pressure (PB), heart rate (HR), and blood oxygen saturation (SpO2) and side effects including dizziness, nausea, vomiting, and sleepiness were assessed. The parents' and the operator's satisfaction rates were scored. Data were analyzed using paired t-test and Wilcoxon signed-rank test. There were significant differences in sedation scores between the two sessions (P<0.05). However, there were no significant differences in alterations of physiologic parameters between the two sessions (P>0.05). Nausea and vomiting were more common during the first two hours in the midazolam group (P=0.002). Tremors were more common in the melatonin group (P=0.013). Dizziness was more evident when melatonin was used (P<0.001). The clinician and the parents were more satisfied with the results of midazolam intake (P<0.05). Premedication with oral midazolam in pediatric patients is superior to that with melatonin with a higher parents' and operator's satisfaction

Vomiting is a common side effect of ketamine in children's sedation and there is still controversy about the use of an anti-emetic drug along with ketamine to reduce this complication. The aim of this study was to evaluate the effectiveness of ondansetron in controlling vomiting induced by intramuscular (IM), and intravenous (IV) ketamine for procedural sedation and analgesia in children in the emergency department (ED).
In a double-blind, randomized, placebo-controlled clinical trial, children aged 1 to 10 years who received ketamine for ED procedures were randomized into four groups receive IV ketamine (1.5 mg/kg), and placebo, IM ketamine (5mg/kg) and placebo, IV ketamine and IV ondansetron (0.15 mg/kg), and IM ketamine and oral ondansetron. The incidence of nausea and vomiting and ED length of stay were compared as the outcome of the study.
One hundred eighty children were enrolled and randomized to four groups; 29 patients (15.0%) had nausea and vomiting. The incidence of vomiting was 26.7% in the IV ketamine-placebo group and 8.9% in the IV ketamine/ IV ondansetron group (P = 0.02). The incidence of vomiting was 17.8% in the IM ketamine-placebo group and 11.1% in the IM ketamine/oral ondansetron group (P = 0.17). ED length of stay was similar between groups.
According to current results, children administered IV ondansetron before IV ketamine experienced a significantly reduced incidence of vomiting but did not significantly affect length of ED stay and the addition of oral ondansetron to IM ketamine dose not reduce vomiting.

The current study aimed at investigating the effect of using Entonox gas during sedation and analgesia induction in pediatric candidates of bone marrow aspiration.
It was a single-blind, randomized clinical trial. All pediatric candidates of first time bone marrow aspiration were included and allocated to either group 1 or 2, using a random number table. In group 1, a combination of midazolam, fentanyl, ketamine, and propofol was injected intravenously. In group 2, the mentioned combination was injected intravenously and Entonox gas was used for patients’ ventilation. The goal was to reach level 4 sedation based on the Ramsay sedation scale. If needed, extra propofol was injected intravenously every minute. Physician and the helping nurse satisfaction of the procedure were evaluated. Duration of the procedure, the administered dosage for each patient, occurrence of any complications, and the recovery time were recorded.
A total of 88 cases with the mean age of 6.8 ± 3.6 years, and mean weight of 25.4 ± 12.5 kg were included in the study (50% female). Baseline and demographic data of the groups showed no significant difference. Propofol consumption was significantly lower in group 2, for whom Entonox gas was prescribed, compared with group 1 (P-value It is likely that Entonox prescription during bone marrow aspiration in pediatric leads to decrease in consumption of propofol to provide proper sedation, shorter recovery time of the patients, and increased satisfaction in both the physician and nurse in charge of performing the procedure.

Midazolam is among routine agents used for inducing safe sedation. This study was designed to compare the sedative effect of oral administration of midazolam (Elixir vs Vial) in fearful children during dental treatment.
A randomized double blind clinical trial was conducted in a cross over style on 20 young fearful aged 3-6 years with Frankl behavioral scale of 1. Children were randomly divided into two groups. Group I received 0.5 mg/kg Midazolam Vial and 1 mg/kg Hydroxyzine oral at their first visit and 0.5 mg/kg Midazolam Elixir and 1 mg/kg Hydroxyzine oral in their second visit. In group II, the medication order was reversed. Houpt scale was used to measure the sedation level in both groups. Vital signs of heart rate and SpO2 were recorded during the procedure. Paired t-test, Wilcoxson and McNamara were employed to statistically analyze and compare the collected data between two groups.
Based on the collected data, Houpt scale was seemingly improved more after taking elixir compare to the vial, however the difference was not statistically significant (P= 0.393). There was no significant difference between the success rate of the two methods (P= 0.625). All physiologic parameters were within the normal range with no significant difference between two groups and sessions.
The level of success between the two groups for sedation was not statistically different and were almost the same. This may indicate a success full use of the vial for oral application in certain cases of compromised cooperation.

The aim of the present study was to compare the effects of intranasal ketamine and midazolam on behavior of 3-6 year-old children during dental treatments.
In this randomized cross-over clinical trial, 17 uncooperative children requiring at least two dental treatments were selected and randomly received ketamine (0.5mg/kg) or midazolam (0.2mg/kg) prior to treatment. The other medication was used in the next visit. The children’s behavioral pattern was determined according to the Houpt's scale regarding sleep, movement, crying and overall behavior. Physiological parameters were also measured at different time intervals. The data were subjected to Wilcoxon Signed Rank test and two-way repeated measures ANOVA.
The frequency of crying decreased significantly following ketamine administration compared to midazolam (P=0.002); movement of children decreased with fewer incidence of treatment interruption (P=0.001) while their sleepiness increased (P=0.003). Despite higher success of sedation with ketamine compared to midazolam, no significant differences were found between the two regarding patients’ overall behavior (P>0.05). The patients had higher heart rate and blood pressure with ketamine; however, no significant difference was found regarding respiratory rate and oxygen saturation (P>0.05).
Ketamine (0.5mg/kg) led to fewer movements, less crying and more sleepiness compared to midazolam (0.2mg/kg). No significant differences were found between the two drugs regarding children’s overall behavior and sedation efficiency. Both drugs demonstrated positive efficacy for sedation of children during dental treatments.
