Insights
CoolSense significantly reduced pain during intravenous cannulation in children compared to EMLA cream. This rapid and effective method offers better analgesia for pediatric venous cannulation.
Area of Science:
- Pediatric Anesthesiology
- Pain Management
- Dermatology
Background:
- Intravenous cannulation is a common procedure in pediatric care.
- Pain and anxiety are significant concerns during pediatric intravenous cannulation.
- Topical anesthetics like EMLA cream are often used but have limitations.
Purpose of the Study:
- To compare the efficacy of CoolSense versus EMLA cream for pain reduction during pediatric intravenous cannulation.
- To evaluate secondary outcomes including anxiety, procedural success, and patient/parent satisfaction.
Main Methods:
- 140 pediatric patients (ASA I/II, 6-12 years) were randomized into two groups.
- Group I received CoolSense pretreatment; Group II received EMLA cream pretreatment.
- Pain scores, anxiety levels, procedural success, and adverse events were assessed.
Main Results:
- CoolSense demonstrated a significantly greater reduction in pain scores compared to EMLA cream (p=0.001).
- The CoolSense group showed a significant decrease in pre- and post-procedural anxiety levels (p=0.003).
- CoolSense required a significantly shorter application duration than EMLA cream.
Conclusions:
- CoolSense is more efficacious than EMLA cream in alleviating pain during pediatric intravenous cannulation.
- CoolSense offers a simple, rapid, and effective analgesic option for venous cannulation in children.
Objective:
To compare the efficacy of CoolSense and EMLA cream on pain reduction during intravenous cannulation in the pediatric population.
Methods:
A total of 140 American Society of Anesthesiologist I/II children of 6-12 y requiring intravenous cannulation before induction of anesthesia were randomized into two groups of 70 each. Before intravenous cannulation, group I received CoolSense pretreatment while group II received EMLA cream pretreatment. The primary outcome was to assess the efficacy of CoolSense and EMLA cream on pain reduction during intravenous cannulation. The secondary outcomes included the anxiety level of children, successful first attempt at cannulation, technical difficulties faced, adverse reactions, and parents' satisfaction score.
Results:
There was a significant reduction in pain scores during intravenous cannulation in the CoolSense group compared to the EMLA cream group (mean pain score 7.14 ± 4.322 versus 29.32 ± 8.95, p value 0.001). Comparison of pre- and postprocedural anxiety levels showed a decrease in the anxiety level in the CoolSense group (p value = 0.003) as compared to the EMLA group. The duration of application of CoolSense was significantly less than EMLA cream.
Conclusion:
CoolSense was more efficacious in reducing the pain of intravenous cannulation than the EMLA cream. In the pediatric population, CoolSense appears to be a simple and rapid means of providing adequate analgesia for venous cannulation.
