Pre-anaesthetic medication in paediatric day-care surgery
Insights
Pre-anaesthetic medication for pediatric day care surgery offers no benefit. This study found no difference in emotional state, anesthesia induction, or recovery between children receiving hydroxyzine, promethazine, diazepam, or placebo.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Pharmacology
Background:
- Pre-anaesthetic medication aims to ensure a smooth and agreeable anesthesia process.
- Evaluating the efficacy of premedication in pediatric patients is crucial for optimizing perioperative care.
- Day care surgery necessitates efficient and safe anesthetic protocols for young patients.
Purpose of the Study:
- To compare the efficacy of hydroxyzine, promethazine, and diazepam against a placebo as pre-anaesthetic medication in children undergoing day care surgery.
- To assess the impact of different premedications on patient's emotional state, anesthesia induction, and recovery.
- To evaluate postoperative complications and parental-reported outcomes following different premedication strategies.
Main Methods:
- A prospective, blinded study involving 159 pediatric patients (1-12 years) randomly assigned to four groups.
- Groups received oral hydroxyzine (0.5 mg/kg), promethazine (0.5 mg/kg), diazepam (0.1 mg/kg), or placebo 60 minutes before surgery.
- Data collected included intraoperative observations (emotional state, induction quality, complications) and recovery room data (emergence time, complications, analgesia needs), supplemented by a 3-day postoperative questionnaire.
Main Results:
- No statistically significant differences were observed between the four groups regarding emotional state, quality of anesthesia induction, or intraoperative complications.
- Recovery room assessments, including time to emergence and need for analgesia, showed no variations across the groups.
- Parental questionnaires did not reveal any significant differences in psychological or physical complications during the three days following surgery.
Conclusions:
- Pharmacological premedication for children undergoing day care surgery provides no discernible benefit.
- The absence of benefit suggests that routine pre-anaesthetic medication may not be indicated in this patient population.
- Further research could explore non-pharmacological approaches to manage anxiety and improve the perioperative experience for pediatric patients.
Abstract:
Pre-anaesthetic medication has the primary aim of making the whole process of anaesthesia smooth and agreeable. This prospective blind study was planned to compare the efficacy of three active drugs and a placebo as premedication in a paediatric population undergoing operation on a day care basis. One hundred and fifty-nine patients between one and 12 years of age were assigned randomly to one of four groups who received either hydroxyzine 0.5 mg . kg-1 (n - 43) promethazine 0.5 mg . kg-1 (n 40) diazepam 0.1 mg . kg (n - 378) or placebo (n - 36) by mouth, 60 minutes before operation. Observations in the operating room included the emotional state of the patient on arrival, quality of induction and complications. In the recovery room time for emergence from anaesthesia, complications and requirements for analgesia were recorded. The parents were asked for return a questionnaire detailing psychological and physical complications during three postoperative days. There was no difference between the groups in any of the factors examined. From this study we conclude that children undergoing surgical operations and anaesthesia on a day care basis should not receive pharmacological premedication, not because of overwhelming risk from its use, but because of the absence of any benefit.
