Premedication during micturating cystourethrogram to achieve sedation and anxiolysis

Area of Science:

• Pediatric Radiology
• Pharmacology
• Medical Imaging

Background:

• Micturating cystourethrogram (MCUG) is crucial for diagnosing pediatric urinary tract conditions.
• Sedation and anxiolysis are often necessary to facilitate MCUG in children.
• Assessing the efficacy and safety of different sedatives is important for patient comfort and procedure success.

Purpose of the Study:

• To evaluate the effectiveness of midazolam and chloral hydrate for sedation and anxiety reduction during MCUG in children.
• To compare the impact of these sedatives versus a control group on patient comfort and procedural outcomes.
• To determine if midazolam or chloral hydrate affect the diagnostic reliability of MCUG.

Main Methods:

• A randomized controlled trial involving 53 children undergoing MCUG.
• Participants were assigned to receive oral midazolam (0.6 mg/kg), chloral hydrate (25 mg/kg), or saline (control).
• Sedation and anxiety levels were assessed using validated scales (Brietkopf and Buttner, Frankl and Houpt, Spielberger's State Anxiety Inventory) and parent impressions.

Main Results:

• Midazolam significantly improved emotional status and sedation compared to the control group (P=0.01 and P=0.018).
• Parents reported catheterization as less distressing in the midazolam group versus control and chloral hydrate groups (P<0.05).
• No significant differences were observed in bladder capacity or detection of residual urine between groups; vital signs remained stable.

Conclusions:

• Midazolam provides effective sedation and anxiolysis for pediatric MCUG, enhancing patient comfort.
• Sedation with midazolam does not adversely affect the diagnostic accuracy of micturating cystourethrogram.
• Midazolam is a safe and beneficial agent for reducing discomfort in children undergoing this radiological examination.
