Tumescent local anaesthesia for early dermatosurgery in infants

Abstract

Background

Early paediatric dermatosurgery reveals excellent cosmetic results due to high skin-elasticity and pronounced capacity to recover from trauma. Furthermore, the size of skin lesions increases during life proportionally to skin growth and therefore early removal is of major importance. Selected local anaesthetics like prilocaine can cause methaemoglobinemia. However, in contrast to general anaesthesia many other local anaesthetics do not bare any major risks for infants.

Objective

In this retrospective study, we analysed infants aged less than 7 months receiving tumescent local anaesthesia (TLA) followed by dermatosurgery at our department between 2005 and 2015. The analysis is mainly based on our records. Additional information for a subset of patients was gained by a postoperative survey.

Methods

92 infants (39 male, 53 female) with a median age of 4.2 months (range: 1.5 months; 6.7 months) were included in this study. Additional postoperative information was available for 33 of the 92 studied patients (35%).

Results

Infants were mainly operated for removal of a melanocytic nevus (n=54), followed by haemangioma (n=23), nevus sebaceous (n=6) and other lesions (n=9). The lesions were located on the scalp or neck (n=31), on the extremities (n=31), on the trunk (n=21), in the face (n=6) or on the buttocks (n=3). The median size of excision was 509mm² (range: 16mm²; 3600mm²). Primary defect closure was performed by intracutaneous (n=68) or extracutaneous (n=24) suture techniques. No side effects of local anaesthesia were observed in any patient. Postoperative complications include pain (1/33; 3%), wound healing disorder (1/33; 3%) and visible severe scarring (2/33; 6%).

Conclusions

The combination of TLA and dermatosurgery in infants is a suitable outpatient treatment option for small lesions without any major risks or side effects and the benefit of prolonged postoperative analgesia.
