Abstract
AIMS AND OBJECTIVES: To compare the efficacy and side effects of profile of topical 2% lidocaine gel with injectable 2% lidocaine solution as local anaesthetics for incision and curettage of chalazion. PATIENTS AND METHODS: Over a 12-month period, 61 patients with unilateral chalazia who were scheduled for incision and curettage surgery under local anaesthesia were randomlzed into two groups: A and B. Group A received 1.5ml of injectable lidocaine as local anaesthetic while group B received 1.5 ml of lidocaine 2% gel topically. The major outcome of interest was pain experienced during anaesthetic administration and surgery. RESULTS: Mean pain score from anaesthesia administration was significantly higher in the injection group (A = 4.46 vs B =0.57), (p = 0.000005). There was a statistically significant difference in mean pain score during incision and curettage with more pain in the gel group (A = 2.84 vs B = 4.83), (p = 0.0012). However, the mean total pain score (surgery plus anaesthesia) was more in the injection than the gel group (A= 7.3 vs B = 5.4) (p= 0.0094). The proportions that had no fear for injection were 54.8% in A and 56.7% in B. Group A had significantly more ptosis than group B (2.2 vs 1.4, p = 0.00003). Bleeding occurred in 93.5% in group A while none occurred in group B (p = 0.000). CONCLUSION: Lidocaine 2% gel is an effective, safe and convenient alternative to injectable lidocaine 2% as local anaesthetic agent in incision and curettage for chalazion in this study.
