Premedication in children: does taste matter?

Added Syrup as a Flavoring to Oral Midazolam Intravenous Solution Premedication Improves Tolerability in Pediatric Patients

Purpose

To investigate the tolerability of midazolam intravenous (IV) solution by masking its bitter taste through the addition of syrup.

Methods

In the waiting area before surgery at our institution, Eye and ENT Hospital, from May to November of 2021, pediatric patients scheduled for anterior ear fistula removal or eardrum catheterization were randomly assigned to receive a mixture of IV midazolam and water (Group C) or IV midazolam and syrup (Group S) in equal volumes. We measured the difference between the groups in terms of drug tolerability with a 5-point facial hedonic scale given to every patient, parent, and nurse involved in the study. Secondary outcomes included sedation and anxiety levels, which were assessed at separation from the parents and general anesthesia induction via a mask.

Results

In total, 180 patients were enrolled. The facial hedonic scales were higher in Group S as evaluated by the children (p=0.046), parents (p=0.020), and nurses (p=0.026). More patients were willing to take the same solution again in Group S than in Group C (p=0.024). The levels of sedation and anxiety at two timepoints were similar between the groups (all p>0.05). No adverse events were noted preoperatively.

Conclusion

The tolerability of IV midazolam administered orally was increased in a pediatric population by adding syrup. The sedative and anxiolytic effects were comparable for both midazolam mixtures.

Comparison of the Effects of Oral Midazolam and Intranasal Dexmedetomidine on Preoperative Sedation and Anesthesia Induction in Children Undergoing Surgeries

Background and Purpose: Premedication with either oral midazolam or intranasal dexmedetomidine prior to surgery remains less than ideal. The aim of this study was to investigate whether the combination of those two drug regimens would have any beneficial effects on the preoperative sedation and the children’s compliance during anesthesia inhalation induction.

Experimental Approach: One hundred thirty-eight children aged 2–6 years were randomly allocated into three groups: Group M with oral midazolam 0.5 mg kg⁻¹, Group D with intranasal dexmedetomidine 2 μg kg⁻¹, and Group M + D with intranasal dexmedetomidine 1 μg kg⁻¹ plus oral midazolam 0.5 mg kg⁻¹. The primary outcome was the children’s compliance during inhalation induction with sevoflurane. The secondary outcomes included the preoperative sedative effects, behavior scores, parental separation anxiety scores, and the postoperative incidence of emergence agitation and recovery time.

Results: Subjects in Group M + D showed higher satisfaction scores of compliance (p = 0.0049) and mask acceptance (MAS) (p = 0.0049) during anesthesia inhalation induction. Subjects in Group M + D had a significantly shorter time than those in Groups M and D to achieve the desired sedation level (p < 0.001) and remained at a higher sedation score in the holding area and up to the anesthesia induction after drug administration (p < 0.001).

Conclusion and Implications: We conclude that pediatric patients premedicated with intranasal dexmedetomidine 1 μg kg⁻¹ plus oral midazolam 0.5 mg kg⁻¹ had significantly improved anesthesia induction compliance, and quicker onset to achieve and maintain a satisfactory level of sedation than those premedicated separately with two drugs. Therefore, the combined premed regimen is a greater choice when we are expecting a higher quality of sedation and a smoother anesthesia induction in children undergoing the surgeries.

Parents' perspectives towards paediatric confectionary masked medications: a qualitative study

Background The availability of age-appropriate, taste-masked oral solid medications for the paediatric population is currently inadequate. We have developed a novel chocolate-based drug delivery platform to taste-mask bitter drugs commonly utilised in the hospital setting, but there is limited evidence regarding parent's perspectives on these medications. Aim To identify key themes regarding parents' perspectives on taste-masked medications that look like confectionary. Additionally, to explore and identify the various barriers and facilitators to using oral medication among the paediatric population.Methods Qualitative descriptive study (July to August 2020) at a single tertiary paediatric hospital (Perth Children's Hospital-PCH). Parents with at least one child (2-18 years) that underwent any elective operation at PCH were included in the study, in total 17 were interviewed. Results The two primary themes that underpinned parent's perspectives on taste-masked medications that look like confectionary were medication safety and taste. Majority of parents supported the use of the proposed medication on the basis that the favourable taste profile will facilitate oral consumption, as opposed to their previous experiences with conventional paediatric medications that do not taste mask the bitter flavour. However, medication safety, in the forms of patient education and appropriate packaging, must be considered to minimise harmful misuse of the proposed medication. Conclusion Participants unanimously support the short-term use of taste-masked medications that look like confectionary, particularly in the hospital setting. However, patient education is highly sought after by parents regarding the role of these medications, to ensure medication safety with their children.

Preoperative anxiety in preschool children: A randomized clinical trial comparing midazolam, clonidine, and dexmedetomidine

INTRODUCTION

Anxiety in pediatric patients may challenge perioperative anesthesiology management and worsen postoperative outcomes. Sedative drugs aimed to reducing anxiety are available with different pharmacologic profiles, and there is no consensus on their effect or the best option for preschool children. In this study, we aimed to compare the effect of three different premedications on anxiety before anesthesia induction in preschool children aged 2-6 years scheduled for elective surgery. The secondary outcomes comprised distress during peripheral catheter (PVC) insertion, compliance at anesthesia induction, and level of sedation.

PATIENTS AND METHODS

In this double-blinded randomized clinical trial, we enrolled 90 participants aged 2-6 years, who were scheduled for elective ear-, nose-and-throat surgery. The participants were randomly assigned to three groups: those who were administered 0.5 mg/kg oral midazolam, 4 µg/kg oral clonidine, or 2 µg/kg intranasal dexmedetomidine. Anxiety, distress during PVC insertion, compliance with mask during preoxygenation, and sedation were measured using the modified Yale Preoperative Anxiety Scale, Behavioral Distress Scale, Induction Compliance Checklist, and Ramsay Sedation Scale, respectively.

RESULTS

Six children who refused premedication were excluded, leaving 84 enrolled patients. At baseline, all groups had similar levels of preoperative anxiety and distress. During anesthesia preparation, anxiety was increased in the children who received clonidine and dexmedetomidine; however, it remained unaltered in the midazolam group. There were no differences in distress during PVC insertion or compliance at induction between the groups. The children in the clonidine and dexmedetomidine groups developed higher levels of sedation than those in the midazolam group.

CONCLUSIONS

In preschool children, midazolam resulted in a more effective anxiolysis and less sedation compared to clonidine and dexmedetomidine.
