Lignocaine: its effects on wound healing.
The British Journal of Surgery
|December 1, 1977
Summary
Local anesthetics like lignocaine can impair wound healing, especially at higher concentrations and when combined with adrenaline. Dilute solutions without adrenaline are recommended for better surgical outcomes.
Area of Science:
- Wound healing research
- Pharmacology of local anesthetics
- Surgical outcomes
Background:
- Clinical observations suggest local anesthetics negatively impact wound healing.
- Lignocaine is a commonly used local anesthetic.
Purpose of the Study:
- To investigate the effect of lignocaine, with and without adrenaline, on skin wound tensile strength in rats.
- To determine optimal lignocaine concentrations and additives for wound healing.
Main Methods:
- Rats' skin wounds were treated with varying concentrations of lignocaine, with and without adrenaline.
- Tensile strength of wounds was measured at 3, 5, and 7 days post-operation.
Main Results:
- Lignocaine adversely affected wound healing at 5 and 7 days.
- Adrenaline potentiated the negative effects of lignocaine on wound healing.
- Both the injection method and lignocaine itself contributed to impaired healing.
Conclusions:
- Dilute solutions of lignocaine are preferable for local anesthesia.
- Using lignocaine without adrenaline is recommended to support optimal wound healing.
