[Efficacy of lidocaine tape for venous cannulation in children]
Insights
Lidocaine tape effectively reduced pain during venous cannulation in children undergoing anesthesia. The tape demonstrated a remarkable pain reduction effect, especially after 120 minutes of application, with minimal adverse effects observed.
Area of Science:
- Pediatric Anesthesiology
- Pain Management
- Dermatology
Background:
- Venous cannulation during anesthetic induction in children can cause significant pain and distress.
- Effective pain reduction strategies are crucial for improving pediatric patient experience and cooperation.
- Lidocaine is a local anesthetic commonly used for topical pain relief.
Purpose of the Study:
- To evaluate the efficacy of lidocaine tape in reducing pain associated with venous cannulation in children.
- To determine the optimal application time for lidocaine tape for pain management.
- To assess the safety and tolerability of lidocaine tape in pediatric patients.
Main Methods:
- A randomized controlled trial involving 135 children scheduled for elective surgery.
- Children were assigned to three groups based on lidocaine tape application time: 30, 60, or 120 minutes.
- Pain was assessed using a standardized pain score during venous cannulation; plasma lidocaine levels were measured in a subset of patients.
Main Results:
- Lidocaine tape achieved pain reduction (pain score 0 or 1) in 81% of all patients.
- The 120-minute application group showed a particularly remarkable pain reduction effect.
- Adverse effects were minimal, with only 6.7% of patients experiencing mild skin redness or itching; plasma lidocaine levels remained below 0.8 mcg/mL.
Conclusions:
- Lidocaine tape is an effective and safe option for reducing pain during venous cannulation in children.
- Longer application times (120 minutes) appear to enhance the analgesic effect.
- The study supports the use of lidocaine tape as a valuable tool in pediatric anesthetic procedures.
Abstract:
We evaluated whether lidocaine tape (3 X 5 cm, contained 18 mg of lidocaine) could reduce pain caused by venous cannulation in children during anesthetic induction. One hundred and thirty-five children scheduled for elective surgery were randomly assigned to three groups according to the application time of the tape (30 min, 60 min and 120 min). Pain assessment was made by using our pain score (0: no response, 1: slight agitation, 2: strong agitation, at the venous cannulation). The effect of pain reduction (pain score 0 and 1) was found in 81 % of all patients. Especially in the group of 120 min, the effect was remarkable. Only 6.7% of all patients had slight adverse effects including skin redness and itching. In another 25 patients (weighing 3.5-30 kg), plasma concentration of lidocaine were measured 120 min after application of a piece of this tape. Arterial blood was sampled at 30 and 120 min after the tape was removed. Plasma lidocaine levels were always below 0.8 mcg.ml-1 In conclusion, the lidocaine tape may be useful and safely applicable for venous cannulation in children.
