The Role of Ibuprofen and Midazolam in Pediatric Dentistry: A Retrospective Study and Neurophysiological Considerations

Background: Managing anxiety and behavior during pediatric dental procedures is challenging. This study examines the effects of combining ibuprofen with midazolam sedation using both behavioral management and clinical hypnosis to improve patient cooperation and reduce post-treatment pain. Methods: A retrospective cohort study of 311 children (mean age 74.2 months, standard deviation (SD) = 24.7) was conducted. Patients received either midazolam with ibuprofen (n = 156) or midazolam only (n = 155). Behavior was assessed using the Venham Behavior Rating Scale and anxiety with the Dental Subscale of Children’s Fear Survey Schedule (CFSS-DS) and the Inventory of Stressful Situations (ISS) questionnaires. Statistical analyses included Mann–Whitney U tests and correlation analyses. Results: Ibuprofen did not significantly improve behavior during procedures (drinking phase 0.61, SD 1.31, p = 0.13; before treatment 0.25, SD 0.93, p = 0.53, anesthesia 1.21, SD 1.55, p = 0.29; after treatment 0.51, SD 1.22, p = 0.68), indicating that pharmacological pain management alone is insufficient to address behavioral challenges. Ibuprofen significantly reduced post-treatment pain, with 7.2% of cases reporting pain in the non-ibuprofen group compared to none in the ibuprofen group (p < 0.05). Conclusions: Ibuprofen had no effect on intraoperative behavior and only a limited effect on post-procedural pain, mainly for more invasive procedures. This study highlights the integration of sedation with behavioral strategies, such as clinical hypnosis, to manage anxiety and improve patient cooperation, aiming to enhance treatment outcomes using this integrative approach to pediatric dentistry. Further research is needed to optimize these strategies and verify them in a prospective setting.

Clinical implications of midazolam in preoperative anxiety and sedation: a review

Preoperative anxiety, a common reaction to the unfamiliar setting of medical procedures, affects 60-80% of patients and can lead to significant psychological and physiological stress. This stress can exacerbate hemodynamic instability during surgery, complicate anesthetic management, and contribute to adverse postoperative outcomes such as increased pain perception, longer recovery times, and extended hospital stays. Midazolam, a short-acting benzodiazepine, is frequently used to address these issues due to its rapid onset and effective anxiolytic and sedative properties. By acting on GABA-A receptors, midazolam provides relief from preoperative anxiety and facilitates smoother anesthesia induction. However, its use is not without risks, including potential respiratory depression, paradoxical reactions, and oversedation, which may be particularly concerning in vulnerable populations. These concerns have prompted exploration of non-pharmacological approaches, such as cognitive-behavioral therapy and mindfulness-based interventions, which can reduce anxiety without the side effects associated with pharmacological agents. This review aims to critically evaluate the clinical implications of midazolam use for preoperative anxiety and sedation, highlighting its efficacy, safety profile, and the growing interest in alternative non-pharmacological strategies.

Comparison of Dexmedetomidine and Midazolam for Preoperative Sedation in Patient Under Going Surgeries Under Spinal Anaesthesia

Preoperative anxiety is a frequent condition. Generally, it starts two days before the operation and reaches its peak just prior to induction of anesthesia. Anxiety, stress, and fear that arise just before the operation and anesthesia may lead to psychological trauma and increase the levels of stress hormones, resulting in undesirable metabolic responses before anesthesia. In our study primary objective was to compare the effectiveness of dexmedetomidine and midazolam with control group in preoperative sedation prior to surgical procedures. Considering the sample size and methodology of the seed article a sample size of 207 was obtained This prospective, hospital based, comparative study was conducted in Department of Anesthesia, Mahatma Gandhi Medical College & Hospital, Jaipur over a period from March 2023 to august 2024. Group C was control, Group D was dexmedetomidine, and Group M was the midazolam group. Patients of Group C were given 100 ml of physiological saline over 10 min. patients of Group D were given 0.25 µg/kg dexmedetomidine in 100 ml physiological saline over 10 min. Group M were given 0.03 mg/kg midazolam in 100 ml physiological saline over 10 min. Group D (dexmedetomidine group) has significantly lower bromage score, Anxiety, and VAS scores, demonstrating better overall recovery, reduced anxiety, and less pain as compare to other two group. Also group D patient show better stabilization of vital parameter.

A Comparison of the Use of Propofol versus Midazolam for Pediatric Magnetic Resonance Imaging Sedation: Retrospective Cohort Study.

The aim of the present study was to do a comparison of the recovery profiles and airway-related adverse events of pediatric magnetic resonance imaging (MRI) sedation patients who received propofol alone to those who received midazolam alone. This retrospective cohort study was approved by the Mutah University Ethical Approval Committee (No. 2378). A search of the patients' medical records was performed between September 2021 and April 2022 to identify children aged 4 months-11 years who received propofol or midazolam for MRI sedation. The patients were subdivided into two groups: Those who had propofol alone (propofol group) and those who received midazolam (midazolam group) for pediatric MRI sedation. In propofol group, a 1-2 mg/kg of propofol bolus was given to have a deep sedation (Ramsay Sedation Scale score of 5). Patients in midazolam group received 0.05 mg/kg of midazolam. During the maintenance state of sedation, the patient received 150 µg/kg/min of propofol, and the infusion rate was adjusted in 25 μg/kg/min increments up or down at the discretion of the anesthesiologists to maintain a state of deep sedation. The major targets of this study were recovery profiles (time to awake and time to discharge) and airway-related intervention ratios in pediatric MRI sedation patients. Patient demographics, MRI sedation, and recovery data, including propofol induction dose, airway intervention, and sedation-related adverse events from the pediatric sedation recovery unit were also collected. The mean (standard deviation [SD]) propofol induction dose was higher compared to midazolam group (2.4 [0.7] mg vs. 1.3 [0.5] mg; mean difference, 1.1 mg; P < 0.001). The mean (SD) infusion rate was higher in propofol group compared to midazolam group (161.3 [37.6] μg/min/kg vs. 116.2 [25.6] μg/min/kg; mean difference 45.1 μg/min/kg; P < 0.001). The mean (SD) propofol total dose was higher in propofol group compared to midazolam group (236.3 [102.4] mg vs. 180.7 [80.9] mg; mean difference, 155.4 mg; P < 0.001). The mean (SD) time to awake was longer in midazolam group compared to propofol group (21.2 [5.6] min vs. 23.0 [7.1] min; mean difference, 1.8 min; P < 0.001). The mean (SD) time to discharge was longer in midazolam group compared to propofol group (34.5 [6.9] min vs. 38.6 [9.4] min; mean difference, 4.1 min; 95% confidence interval, 3.0-5.1; P < 0.001). The administration of midazolam during pediatric MRI sedation can decrease the frequency of airway complications without prolonging the clinically significant recovery profile.

Comparison of remimazolam and midazolam for sedation during colonoscopy in Japanese patients: A propensity score matching analysis.

To compare the efficacy and safety of sedation with midazolam and remimazolam for colorectal endoscopy. This single-center, two-arm, post-hoc analysis of the REM-IICTJP01 study investigated the efficacy and safety of remimazolam for gastrointestinal endoscopic sedation. We enrolled 40 and 208 patients who underwent colonoscopy under remimazolam and midazolam sedation, respectively, during the same period. The primary outcome was the time from the end of the colonoscopy until discharge. The secondary outcomes included the time from the end of the colonoscopy until awakening, dosage, and adverse events. Propensity score matching was employed to eliminate the effect of confounding factors. Thirty-seven patients in each group were matched. After propensity matching, the time to awakening after colonoscopy was 28.0 (13.0-37.0) min in the midazolam group and 0 (0-0) min in the remimazolam group; moreover, the time till discharge was 40.0 (35.0-46.5) min in the midazolam group and 0 (0-5.0) min in the remimazolam group, both of which were significantly shorter in the remimazolam group (p < 0.01). The number of additional doses was 0 (0-0) and 2 (1-3) in the midazolam and remimazolam groups, respectively. The total dose was 2.0 (2.0-3.5) and 6.0 (5.0-7.0) mg in the midazolam and remimazolam groups, respectively. Remimazolam yielded significantly faster times to awakening and discharge safely compared to midazolam.

Critical Management of Recurrent Seizure at 16-Year-Old Primigravida with Atypical Eclampsia: A Case Report

Background: Atypical eclampsia, characterized by seizures without the classic signs of hypertension and proteinuria, presents a diagnostic and therapeutic challenge in the critical management aspect. This case report highlights the critical management of recurrent seizures in a young primigravida with atypical eclampsia. Case presentation: A 16-year-old primigravida at 38 weeks gestation presented with recurrent generalized tonic-clonic seizures. Despite initial magnesium sulfate therapy, seizures persisted postpartum. The patient was managed with a combination of midazolam and dexmedetomidine for seizure control and sedation. After five days of intensive care, the patient recovered without further complications. Conclusion: This case underscores the importance of considering atypical eclampsia in pregnant women presenting with seizures, even in the absence of typical preeclampsia symptoms. The successful use of midazolam and dexmedetomidine in this case suggests their potential as alternative therapeutic agents for refractory seizures in eclampsia. Further research is needed to validate these findings and establish optimal treatment protocols for atypical eclampsia.

Dexmedetomidine Moderate Sedation Versus General Anesthesia on the Diagnostic Yield of Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration: A Randomized Controlled Study.

One of the factors that affect the diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the level of sedation. Therefore, we aimed to compare dexmedetomidine (DEX) as moderate sedation (MS) versus general anesthesia (GA) on the diagnostic yield of EBUS-TBNA. This randomized open-label controlled trial was carried out on 70 patients older than 18 years of age, classified as American Society of Anesthesiologists (ASA) II or III, and scheduled for EBUS-TBNA. Patients were randomly allocated into two equal groups. Group D received 1 μg/kg fentanyl 2 minutes before induction with a 1 μg/kg infusion of DEX for 10 minutes, then maintenance with 0.5 - 1 μg/kg/h aiming for a Ramsey Sedation Scale of 4 - 5 while preserving hemodynamics. Group GA received 1 μg/kg fentanyl, 2 mg/kg propofol, and 0.5 mg/kg atracurium (then 0.1 mg/kg every 20 minutes). Group D had a significantly higher rate of recalling the procedure (P = 0.005) and a lower rate of shortness of breath compared to group GA (P = 0.038). Intraoperative heart rate measurements at baseline were not significantly different between groups but were significantly lower at 5 min, 10 min, 15 min, 20 min, and at the end of surgery in group D compared to group GA (P < 0.05). Intraoperative mean arterial blood pressure measurements at baseline, 5 min, 10 min, 15 min, 20 min, and at the end of surgery were not significantly different between groups. Recovery time was significantly shorter in group D compared to group GA (P < 0.001). Compared to GA, MS with DEX showed a comparable diagnostic yield with faster recovery time and better patient satisfaction, as evidenced by a willingness to repeat procedures when needed and less shortness of breath in EBUS-TBNA.

Prehospital Use of Ketamine Versus Midazolam for Sedation in Acute Severe Agitation

Objective: Acute severe agitation often requires pharmacologic sedation. While benzodiazepines and antipsychotics are traditional first-line medications for this purpose, recent evidence has shown that prehospital intramuscular (IM) administration of ketamine results in rapid, effective sedation. However, ketamine may be associated with adverse clinical events including a higher intubation rate. The purpose of this study is to compare the efficacy and safety of IM ketamine versus IM midazolam as medications to achieve sedation in the prehospital setting. Methods: This is a retrospective cohort study of agitated patients with an initial Richmond Agitation-Sedation Scale (RASS) score of at least 3, who were sedated and transported by ambulance to Hartford Hospital. The primary endpoint was incidence of endotracheal intubation occurring during transportation and within one hour after arrival to the emergency department (ED). Secondary endpoints included the percentage of patients who achieved an improved RASS score post drug administration, the use of additional sedating agents and the need for airway and breathing support, and differences in adverse events. Results: 66 patients in the ketamine group and 68 patients in the midazolam group met inclusion criteria. While more patients in the midazolam group achieved target RASS score of -1, 0, or 1 post drug administration, patients in the ketamine group had a lower mean RASS score post drug administration. There was no difference in endotracheal intubation rates between the two groups (6.1% versus 2.9%, respectively; p = 0.383). However, upon arrival to the ED, more patients in the ketamine group required additional sedating agents as well as airway or respiratory support Conclusion: Both ketamine and midazolam are relatively safe and efficacious in the prehospital environment. IM ketamine resulted in deeper sedation without increasing intubation rate. However, ED providers receiving patients treated with IM ketamine should prepare for additional sedating agents and airway interventions.

Utility of Neonatal Pain, Agitation and Sedation Scale and Amplitude Integrated Electroencephalogram for Detection of Different Levels of Sedation in NICUs

Abstract Background Sedatives are essential drugs in every intensive care unit used to ensure the patient's optimal level of comfort. Avoiding conditions of over and under sedation is a challenge in a neonatal intensive care setting. To date, there are no definitions of optimal levels of sedation in neonates. Testing the hypothesis that if a combined use of Neonatal Pain, Agitation and Sedation Scale (N- PASS) and amplitude integrated electroencephalography (aEEG) score might be helpful to distinguish different levels of neonatal sedation and therefore useful in titration of the drugs used. Aim of the Work The primary aim of the present study is to assess Neonatal Pain, Agitation and Sedation Scale (N-PASS) and amplitude integrated electroencephalography (aEEG) in the detection of different levels of neonatal sedation. Patients and Methods This was prospective observational study conducted on 30 full term neonates on mechanical ventilation reciving sedation (midazolam,fentanyl). we divided our patients into two groups (lightly sedated and deeply sedated patients) according to dose of sedation which determined by the expert opinion according to the clinical condition of the patients. all patients were subjected to the following:(demographic data, clinical signs &amp; symptoms, laboratory investigations, N-PASS and aEEG before and after sedation from march 2021 to August 2022 to evaluate N-PASS and aEEG in the detection of different levels of neonatal sedation. Results In our study which was conducted on 30 patients admitted to NICU at Ain shams university hospitals, our patients were of mean gestational age 38.34, all patients presented with respiratory distress, were mechanically ventilated and received sedation (midazolam, fentanyl). we divided our patients into two groups (lightly sedated patients who were 11 patients (36.7%), deeply sedated patients who were 19 patients ( 63.3% ) according to dose of sedation. There was a significant decrease of co2 level in deeply sedated patients, mean co2 after deep sedation 43.36 mmHg while mean co2 after light sedation 51.52 mmHg (p 0.034),and regarding N-PASS significant decrease in N-PASS total score after sedation (p &amp;lt; 0.001 ),and regarding aEEG significant decrease of total burdjalov score after sedation (p &amp;lt; 0.001 ) Conclusion We recommend combining a clinical scoring system such as the N-PASS, with a continuous brain activity monitor such as the aEEG for assessing the level of sedation in neonates.

Comparison of Changes in Rso2 in Midazolam and Propofol Sedation Post Craniotomy in the Icu of H. Adam Malik Hospital

Introduction: Cerebral oxygen saturation reflects tissue perfusion in the cerebrum. Decreases in cerebral oxygen saturation are linked to longer hospital stays and cognitive impairment. Midazolam and propofol can decrease cerebral blood flow through decreasing the cerebral oxygen metabolic rate. The purpose of this research is to analyze the comparison of changes in cerebral oxygen saturation after midazolam and propofol administration in post-craniotomy patients in the ICU of Haji Adam Malik General Hospital Medan. Subject and Method: This is a randomized control trial study. Patients were divided into, Midazolam group, that given an initial dose of 0.05 mg/kg followed by a maintenance dose of 0.02-0.10 mg/kg/hour and Propofol group that given sedation with a dose of 0.3-3mg/kg/hour, with the target of the 2 groups being a Richmond Agitation-Sedation Scale (RASS) value of 0 to -2. Data analysis using unpaired T test. Results: The results for cerebral regional oxygen saturation and RASS between groups showed significant differences in right and left value (p &lt; 0.001), but there was no significant difference in RASS (p&gt;0.05) between each group at each measurement time. The results of the analysis of cerebral regional oxygen saturation and RASS between times, there was no significant difference in right and left value (p&gt;0.05), but there was a significant difference in RASS (p&lt;0.001) at each measurement time. Based on the results of the analysis carried out, it is known that there is no statistically significant difference in changes in cerebral regional oxygen saturation both right and left in changes in RASS because it is found that all data have p&gt;0.05. Conclusion: There is no change in right and left for cerebral regional oxygen saturation after administration of propofol and midazolam groups with RASS value 0 to -2 in post-craniotomy patients in the ICU of Haji Adam Malik General Hospital Medan

Early Postnatal Exposure to Midazolam Causes Lasting Histological and Neurobehavioral Deficits via Activation of the mTOR Pathway.

Exposure to general anesthetics can adversely affect brain development, but there is little study of sedative agents used in intensive care that act via similar pharmacologic mechanisms. Using quantitative immunohistochemistry and neurobehavioral testing and an established protocol for murine sedation, we tested the hypothesis that lengthy, repetitive exposure to midazolam, a commonly used sedative in pediatric intensive care, interferes with neuronal development and subsequent cognitive function via actions on the mechanistic target of rapamycin (mTOR) pathway. We found that mice in the midazolam sedation group exhibited a chronic, significant increase in the expression of mTOR activity pathway markers in comparison to controls. Furthermore, both neurobehavioral outcomes, deficits in Y-maze and fear-conditioning performance, and neuropathologic effects of midazolam sedation exposure, including disrupted dendritic arborization and synaptogenesis, were ameliorated via treatment with rapamycin, a pharmacologic mTOR pathway inhibitor. We conclude that prolonged, repetitive exposure to midazolam sedation interferes with the development of neural circuitry via a pathologic increase in mTOR pathway signaling during brain development that has lasting consequences for both brain structure and function.

Comparison of propofol-based sedation and midazolam sedation in pediatric bidirectional endoscopy conducted by pediatric gastroenterologists.

The effectiveness and safety of propofol-based sedation and midazolam sedation in pediatric bidirectional endoscopy were compared. We retrospectively analyzed the cases of pediatric patients (≤15 years old) who had undergone bidirectional endoscopy, esophagogastroduodenoscopy, and colonoscopy by pediatric gastroenterologists. Demographic data, indications, sedatives/dosages, clinical outcomes, endoscopic findings, adverse events, and total patient time requirements (total time in which patients stay in our hospital) were compared in the two sedation groups. Ninety-one children (51 boys, 40 girls, mean age 13 years, range 9-15) treated at our hospital were enrolled. Propofol alone or in combination with midazolam and/or pentazocine was administered to 51 patients (propofol-based sedation group). Midazolam alone or in combination with pentazocine was administered to the other 40 patients (midazolam sedation group). In the propofol group, the following mean doses were used: propofol, 96 mg (range 40-145 mg); midazolam, 4.9 mg (range 3-5 mg); and pentazocine, 7.5 mg. In the midazolam group, the mean doses of midazolam and pentazocine were 6.2 mg (range 4-10 mg) and 15 mg, respectively. All procedures were successfully completed by pediatric gastroenterologists. The total procedure times and endoscopic findings were similar in the two groups, but the median patient time requirement in the propofol group was significantly shorter versus the midazolam group (7.3 h vs. 8.4 h, p < 0.001). No adverse events occurred in either group. Propofol-based sedation in pediatric bidirectional endoscopy was safely and effectively performed by pediatric gastroenterologists, and its patient time requirement was shorter than that for midazolam sedation.

Safety and Efficacy of Conscious Sedation Versus General Anesthesia for Distal Vessel Thrombectomy

BACKGROUND AND OBJECTIVES: Anesthesia modality for endovascular thrombectomy (EVT) for distal and medium vessel occlusions remains an open question. General anesthesia (GA) may offer advantages over conscious sedation (CS) because of reduced patient movement facilitating catheter navigation, but concerns persist about potential delays and hypotension affecting collateral circulation. METHODS: In our prospectively maintained stroke registry from December 2014 to July 2023, we identified patients with distal and medium vessel occlusions defined as M2, M3, or M4 occlusion; A1 or A2 occlusion; and P1 or P2 occlusion, who underwent EVT for acute ischemic stroke. We compared patients who received CS with those who received GA. Primary outcomes were early neurological improvement (ENI), successful reperfusion, first-pass effect, and good outcome at 90 days. Secondary outcomes included intracerebral hemorrhage, subarachnoid hemorrhage, and 90-day mortality. RESULTS: Of 279 patients, 69 (24.7%) received GA, whereas 193 (69.2%) received CS. CS was associated with higher odds of ENI compared with GA (odds ratio [OR] 2.59, 95% CI [1.04-6.98], P &lt; .05). CS was also associated with higher rates of successful reperfusion (OR 2.33, 95% CI [1.11-4.93], P &lt; .05). CS nonsignificantly trended toward lower rates of mortality (OR 0.51, 95% CI [0.2-1.3], P = .16). No differences in good outcome at 90 days, intracerebral hemorrhage, subarachnoid hemorrhage, or first-pass effect were seen. CONCLUSION: The use of CS during EVT seems to be safe and feasible with regard to successful recanalization, hemorrhagic complications, clinical outcome, and mortality. In addition, it may be associated with a higher rate of ENI. Further randomized studies in this specific EVT subpopulation are warranted.

Objective randomised blinded investigation of therapeutic ablation versus cardioversion for persistent atrial fibrillation- outcomes of the feasibility

Abstract Background Patients with persistent atrial fibrillation (pers.AF) commonly undergo catheter ablation (CA) for symptom relief and improved quality of life(QoL). However,the benefits of CA compared to DC cardioversion (DCCV) or medical therapy lack substantial evidence from blinded randomized trials. Purpose Conducting such a large-scale trial presents substantial challenges in terms of recruitment, maintaining blinding, and implementation.To address this, we conducted a pilot study prior to a definitive larger study. Methods This feasibility trial is a single-centre, prospective, randomised, double-blinded placebo control study. Patients with early pers AF (&amp;lt;2 years) eligible for pulmonary vein isolation (PVI) or DCCV were enrolled. Twenty patients were recruited, accounting for 10% of the proposed larger trial based on power calculation. The intervention arm (PVI + DCCV) and placebo arm (Placebo + DCCV) were randomised in a 1:1 manner after ultrasound-guided vascular access with local anaesthetic and deep sedation (Midazolam + opioid). All procedures were performed as day cases on uninterrupted oral anticoagulation. Phrenic nerve pacing was performed in the Placebo group, mimicking lab interactions and fluoroscopy system movements. Implantable loop monitors were inserted immediately after heparin reversal and groin sheath removal. A 6-week(wk) blanking period was observed post-procedure. Blinding was assessed using Bang's blinding index (BI) for both patients and medical staff and a successful blinding is considered BI between -0.2 to 0.2. Health-related quality of life (HRQoL) was evaluated using SF12, EQ5D-5L, and AF PROMS. The study obtained ethical approval (REC ref 19/LO/0775),adhered to the principles of the Declaration of Helsinki,and obtained written informed consent from all participants. Results A remarkable 92% of patients approached, expressed a willingness to participate in the study. Procedure time and time to discharge were similar between groups. The study successfully achieved blinding among the patients at day0 (BI = PVI-0.2 vs placebo- 0) and was maintained throughout the 6-wk and 3M follow-up, among the patients as well as clinical staff. HRQoL improved in the active group in terms of AF PROMS [Improved difference from baseline PVI 23 (±22); vs Placebo 2 (±10), p=&amp;lt;0.001 and SF-12 mental component (MCS) at 12M (PVI 11.8 (±11) vs placebo 8.54(±11.5), p= 0.017). Over a follow up period of 12M, there was a trend towards greater recurrence (60% vs 30%; p=0.07) and repeat procedures (70% vs 40%; p=0.4) in the placebo group. Conclusion: Performing a blinded placebo-controlled interventional study to assess the efficacy of PVI is feasible and high recruitment rates are achievable. CA appears to result in better arrhythmic and QoL outcomes;a full-scale follow-on study will assess the true efficacy of CA in patients with early pers.AF and allow consideration of whether there is a role for DCCV in many patients.

Efficacy and Safety of Dexmedetomidine Compared to Other Needle-Free Pharmacological Sedation Methods in Pediatric Patients Undergoing Imaging Procedures.

Pediatric patients often require sedation during magnetic resonance imaging (MRI) and computed tomography (CT) to ensure stillness and minimize stress. This meta-analysis compared the effectiveness and safety of 3 sedative agents-dexmedetomidine, midazolam, and chloral hydrate-for pediatric MRI/CT sedation. Six studies with a total of 633 patients were included in the analysis. Quality assessment revealed varying levels of bias risk. Dexmedetomidine exhibited a significantly higher successful sedation rate compared to midazolam (risk ratio [RR] = 0.43, 95% confidence interval [CI] [0.29-0.64]), but no statistically significant difference compared to chloral hydrate (RR = 0.94, 95% CI [0.60-1.45]). Chloral hydrate also showed a higher successful sedation rate compared to midazolam (RR = 0.46, 95% CI [0.25-0.83]). The onset of sedation time did not significantly differ between the 3 agents. The dexmedetomidine group had a significantly higher incidence of bradycardia compared to the chloral hydrate group (RR = 0.17, 95% CI [0.05-0.59]), but no significant difference compared to the midazolam group (RR = 0.29, 95% CI [0.06-1.26]). No statistically significant differences were observed in the incidence of nausea and vomiting between the 3 groups. Dexmedetomidine demonstrates effectiveness in pediatric MRI/CT sedation, offering advantages over midazolam and similar efficacy to chloral hydrate. Careful cardiovascular monitoring is essential during administration, particularly in patients with congenital heart disease. Sublingual and intranasal administration of dexmedetomidine is a viable option with high bioavailability. This meta-analysis contributes valuable insights into refining sedation protocols for pediatric imaging procedures, emphasizing efficacy and safety considerations.

Midazolam for Post-Arrest Sedation in Pre-Hospital Emergency Care.

An out-of-hospital cardiac arrest (OHCA) with return of spontaneous circulation (ROSC) may need to be treated with airway management, emergency ventilation, invasive interventions, and post-arrest sedation. We investigated the influence of the use of midazolam for post-arrest sedation on achieving postresuscitation care targets and the associated risk of hemodynamic complications. All emergency rescue missions of the Dresden, Gütersloh, and Lippe medical rescue services in the years 2019-2021 were reviewed to identify adult patients who had OHCA, unconsciousness, and sustained ROSC with spontaneous circulation until arrival at the hospital; the findings were supplemented with data from the German Resuscitation Registry. Patients who received midazolam (alone or in combination with other anesthetic agents) for post-arrest sedation were compared with those who did not. The endpoints were the regaining of a systolic blood pressure ≥ 100 mmHg, end-tidal pCO2 35-45 mmHg, and oxygen saturation (SpO2) 94-98%. A propensity score analysis was used to adjust for age, sex, and variables potentially affecting hemodynamic status or the targets for oxygenation and ventilation. There were 2335 cases of OHCA among 391 305 emer - gency rescue missions. 571 patients had ROSC before arrival in the hospital (24.5%; female, 33.6%; age, 68 ± 14 years). Of the 395 among them (69.2%) who were treated with postarrest sedation, 249 (63.0%) received midazolam. Patients who received midazolam reached the guideline- recommended targets for oxygenation, ventilation, and blood pressure more frequently than those who were not sedated: the respective odds ratios and 95% confidence intervals were 2.00 [1.20; 3.34], 1.57 [0.99; 2.48], and 1.41 [0.89; 2.21]. The pre-hospital administration of midazolam leads to more frequent pre-hospital attainment of the oxygenation and ventilation targets in post-resuscitation care, without any evidence of an elevated risk of hemodynamic complications.

Safety and efficacy of a low-dose combination of midazolam, alfentanil, and propofol for deep sedation of elderly patients undergoing ERCP

BackgroundProper sedation of patients, particularly elderly individuals, who are more susceptible to sedation-related complications, is of significant importance in endoscopic retrograde cholangiopancreatography (ERCP). This study aims to assess the safety and efficacy of a low-dose combination of midazolam, alfentanil, and propofol for deep sedation in elderly patients undergoing ERCP, compared to a group of middle-aged patients.MethodsThe medical records of 610 patients with common bile duct stones who underwent elective ERCP under deep sedation with a three-drug regimen, including midazolam, alfentanil, and propofol at Shandong Provincial Third Hospital from January 2023 to September 2023 were retrospectively reviewed in this study. Patients were categorized into three groups: middle-aged (50–64 years, n = 202), elderly (65–79 years, n = 216), and very elderly (≥ 80 years, n = 192). Intraoperative vital signs and complications were compared among these groups.ResultsThe three groups showed no significant difference in terms of intraoperative variation of systolic blood pressure (P = 0.291), diastolic blood pressure (P = 0.737), heart rate (P = 0.107), peripheral oxygen saturation (P = 0.188), bispectral index (P = 0.158), and the occurrence of sedation-related adverse events including hypotension (P = 0.170) and hypoxemia (P = 0.423).ConclusionThe results suggest that a low-dose three-drug regimen consisting of midazolam, alfentanil, and propofol seems safe and effective for deep sedation of elderly and very elderly patients undergoing ERCP procedures. However, further studies are required to verify these findings and clarify the benefits and risks of this method.

Comparative evaluation of intranasal dexmedetomidine, intranasal midazolam, and nitrous oxide for conscious sedation of anxious children undergoing dental treatment: A randomized cross-over trial.

Pharmacological methods, specifically sedatives, have gained popularity in managing the behavior of children during dental appointments. The aim of this study was to compare 1 m/kg intranasal dexmedetomidine, 0.3 mg/kg intranasal midazolam, and nitrous oxide in evaluating the level of sedation, behavior of the child, onset of sedation, physiologic signs, and adverse effects. In this cross-over trial, 15 children aged 6-8 years were randomized to receive intranasal atomized dexmedetomidine, intranasal atomized midazolam, and inhalation nitrous oxide at three separate visits. After administering the sedative agent, a single pulpectomy was performed during each appointment, and the outcomes were recorded. The washout period between each visit was 1 week. All three sedative agents were equally effective in controlling overall behavior. Dexmedetomidine showed lower sedation level scores (agitated; score 9) than the other groups. There was a statistically significant difference in the onset of sedation, with dexmedetomidine having the longest onset of 36.2 ± 9.47 min. Coughing and sneezing were predominantly observed after administration of intranasal midazolam. Oxygen saturation levels were statistically lower in the intranasal midazolam group during local anesthesia administration and post-treatment. 0.3 mg/kg intranasal midazolam is as effective as nitrous oxide sedation for controlling behavior and providing adequate sedation in pediatric dental patients. However, 1 m/kg dexmedetomidine did not provide the same level of sedation and had a significantly longer onset. 0.3 mg/kg intranasal midazolam is an effective alternative to nitrous oxide sedation in anxious children.
