A comparison of intranasal dexmeditomidine versus intranasal midazolam as a pre anesthetic medication in children undergoing adenotonsillectomy

Background Adenotonsillectomy is one of the most common surgical procedures performed on pediatric patients. Relieving pre- and post-operative anxiety is an important concern for the pediatric anesthesiologist. Aim of the Work: to compare dexmedetomidine with midazolam effect on preoperative sedation, the ease of children parent separation, the mask tolerance, intraoperative hemodynamics stability, emergence of anesthesia and postoperative analgesia. Patients and Methods A Prospective, randomized and double blind controlled clinical trial was done after approval of institutional ethics committee in Ain Shams university Hospitals for 6 months and obtaining an informed written consent from parents. It was designed to include fifty pediatric patients, aged 5 to 10 years old of both genders, with physical status ASA Ι. Results statistically significant increase mean of Dexmedetomidine compared to midazolam according to sedation score after 15min. to after 45min. Conclusion Premedication with intranasal dexmedetomidine 1 μg/kg attained significant and satisfactory sedation with better parent separation and lower anxiety levels without any adverse effects as compared with intranasal midazolam 0.2 mg/kg in children undergoing adenotonsillectomy.

19 Anxiolysis for laceration repair in children: A survey of pediatric emergency providers in Canada

Primary Subject area Emergency Medicine - Paediatric Background Laceration repair accounts for half of procedures performed in pediatric emergency departments. Although commonly used, topical anesthetics do little to alleviate emotional distress, particularly in young children. Intranasal midazolam is frequently used but is not consistently effective. Intranasal dexmedetomidine (IND) is a new and potentially effective anxiolytic but clinical uptake is limited by a lack of pediatric data. Objectives Our objective was to understand pediatric emergency providers’ willingness, preferences, and perceived barriers surrounding anxiolysis for laceration repair in children, to inform the design of a future clinical trial of IND. Design/Methods This was an online survey of Canadian pediatric emergency providers listed in the Pediatric Emergency Research Canada database. The survey was developed according to published guidelines and featured a vignette of a 3-year-old distressed child requiring laceration repair. It was hosted on the Research Electronic Data Capture platform in English and French, and was disseminated from September to December 2020. The primary outcome was the proportion of respondents that would provide anxiolysis. Secondary outcomes included perceived barriers to IND use. Data were reported using summary statistics. Results The response rate was 155/225 (68.9%), of which 98/141 (70%) were Royal College accredited pediatric emergency physicians. For 129/147 (88%) of respondents, 80-100% of their patients were children. 123/146 (84%) had > 6 years independent practice experience and 126/146 (86%) performed > 4 laceration repairs per month. 127/148 (86%) believed that > 25% of children experienced distress significant enough to require physical restraint during laceration repair. 116/148 (78%) indicated they would provide anxiolysis, mainly as intranasal benzodiazepines, such as midazolam (100/109, 92%). 95/148 (64%) indicated that they would consider IND if evidence suggested it was effective. Common perceived barriers included inadequate personal (114/145, 79%) and nursing (109/145, 75%) experience with IND, and lack of formulary access to IND (60/145, 41%). Conclusion Most pediatric emergency providers believe that laceration repair in a young child is distressing and would provide anxiolysis. Most providers would consider IND if there was evidence of benefit, suggesting that favourable findings from a clinical trial would have good clinical uptake.

The Frequency of Emergence Delirium in Children Undergoing Outpatient Anaesthesia for Magnetic Resonance Imaging

Background: The aim of this study was to investigate the effect on the occurrence of emergence delirium of propofol and ketofol with intranasal dexmedetomidine and midazolam applied as premedication to paediatric patients during magnetic resonance imaging (MRI). Methods: The study included children aged 2-10 years who received sedation for MRI, separated into four groups. Group MP received intranasal midazolam (0.2 mg/kg) for premedication and IV propofol (1 mg/kg) as the anaesthetic agent. Group MK received intranasal midazolam (0.2 mg/kg) for premedication and IV ketofol (1 mg/kg) as the anaesthetic agent. Group DP received intranasal dexmedetomidine (1 mcg/kg) for premedication and IV propofol (1 mg/kg) as the anaesthetic agent. Group DK received intranasal dexmedetomidine (1 mcg/kg) for premedication and IV ketofol (1 mg/kg) as the anaesthetic agent. The Paediatric Anaesthesia Emergence Delirium (PAED) scale was used to evaluate delirium. A PAED score ≥ 10 was accepted as delirium. Results: The need for additional anaesthetic was highest in Group DP at 94.3% and lowest in Group DK at 14.3%. The mean Aldrete and PAED scores were lower and the length of stay in the recovery room was shorter in Group DP than in the other groups. Delirium only developed in two patients in Group MP (5.7%) at 5 mins after anaesthesia. Conclusion: In our study, delirium was seen at a very low rate only in the Group MP and it is difficult to say the best combination in terms of delirium frequency with this result.

COMPARISON OF INTRANASAL DEXMEDETOMIDINE V/S MIDAZOLAM AS A PREMEDICATION IN CHIDREN WITH CONGENITAL HEART DISEASE UNDERGOING CARDIAC SURGERY

Background: The intranasal route is a reliable way to administer preanaesthetics and sedatives to children. The aim of present study was to compare the anxiolytic and sedative effects of intranasal dexemedetomidine and midazolam as a premedication in children with congenital heart disease undergoing cardiac surgery.. Patients and Methods: Fifty chidrens 2-12 years of age group of either sex with congenital heart disease undergoing cardiac surgery were randomly allocated into two groups. Group A-(n=25) - received intranasal dexmedetomidine as premedication.(0.1 µg/kg diluted in 2ml NS ) Group B- (n=25)- received intranasal midazolam as premedication. (0.2 mg/kg diluted in 2ml NS) Heart rate, mean arterial blood pressure and oxygen saturation were monitored upto30 minute after drug administration. The sedation score, anxiety score and child separation score were recorded until the child taken to the OR. The postoperative agitation score was also observed. Results and Conclusion: Premedication with intranasal dexmedetomidine attained significant and satisfactory sedation with better parental separation and lower anxiety levels without any adverse effects as compared with intranasal midazolam in children with congenital heart disease undergoing cardiac surgery.
