Brief Summary:
This prospective comparative study evaluates pain experience in adult patients undergoing laceration repair in the emergency department using either topical lidocaine-adrenaline-tetracaine (LAT) gel or lidocaine infiltration as local anaesthesia. Lidocaine infiltration is the standard anaesthetic technique for wound repair but can cause significant pain during injection. LAT gel is a needle-free topical anaesthetic that is widely used in paediatric patients but has been less studied in adults.
Adult patients presenting with simple lacerations requiring suturing are allocated to receive either LAT gel or lidocaine infiltration according to the clinical judgement of the treating physician. Pain is measured using a visual analogue scale (VAS) during anaesthetic administration, during testing of anaesthetic effectiveness, and during suturing. Additional variables include wound characteristics, patient characteristics, and the need for additional anaesthesia. The study aims to evaluate whether LAT gel provides comparable pain control while reducing pain during anaesthetic administration.
Detailed Description:
Pain management is an important component of wound treatment in the emergency department. Local anaesthesia is routinely required for laceration repair, most commonly using infiltrative anaesthesia with lidocaine. Although effective, lidocaine infiltration can cause significant discomfort due to the injection itself and may increase patient anxiety. In addition, infiltration can sometimes distort tissue and potentially complicate the suturing procedure. Alternative approaches that reduce pain during anaesthetic administration may therefore improve patient comfort during wound management.
Topical anaesthesia using lidocaine-adrenaline-tetracaine (LAT) gel represents a needle-free alternative to infiltrative anaesthesia. LAT gel is commonly used in paediatric patients and has demonstrated effectiveness in reducing pain during laceration repair. However, evidence regarding its use in adult patients remains limited. Evaluating the effectiveness of LAT gel in adults may help determine whether it can be used more broadly as an alternative to injection-based anaesthesia in the emergency department.
This prospective comparative study includes adult patients presenting to the emergency department of Universitair Ziekenhuis Brussel with simple lacerations requiring suturing. Patients receive either LAT gel or lidocaine infiltration as local anaesthesia according to the clinical judgement of the attending physician. Pain experience is measured using a visual analogue scale (VAS) during anaesthetic administration, during testing of anaesthetic adequacy, and during suturing. Additional variables recorded include patient characteristics, wound characteristics, suturing characteristics, the need for additional anaesthesia, and procedure-related complications. The aim of the study is to compare pain experience between both anaesthetic techniques and to assess whether LAT gel may represent a suitable alternative for selected adult lacerations.
