Monitoring of a free flap or a perforator flap is important in the immediate postoperative period to alert the surgeon of a vascular event and to enable flap salvage by early intervention.
Monitoring is usually done by nurses.
There are many methods of flap monitoring. The conventional method  of flap monitoring with a hand-held Doppler is a common method employed by doctors and nurses in the immediate postoperative period. Accurately placing the Doppler on the site of the perforator is important for proper flap monitoring. The site to be assessed by the Doppler (i.e., the site of the perforator) is usually marked by scoring the skin or marking by ink on the surface of the flap at the end of surgery. We are presenting here a simple method we have employed over the past 3 years to mark the site of the perforator which has a reliable accuracy in assessing and monitoring with different observers.
The normal self-adhesive electrocardiogram (ECG) lead is taken [Figure 1], the centre part is removed, leaving a hole in the middle [Figure 2]. At the end of the surgery, the surgeon places the ECG lead with the centre directly lying on the perforator to be assessed [Figure 3] and [Figure 4]. The lead stays on the first 5 days and makes it easy for everyone to place the Doppler consistently in the right spot. Caution calls due to doubts about the vascular status of the flap have become much lower ever since we started this method for marking.

This method of marking for flap monitoring is better, because there is no need to worry about the marking being erased with sweat and moisture, as it happens when marked with ink or the scored skin not being visible due to rapid epidermal healing.
This method of marking can be used in all places the Doppler is used, such as in monitoring the perforator in case of the anterolateral thigh (ALT) flap [Figure 3], radial artery flap, free fibular flap, anastomotic site in cases of buried flap [Figure 4], when other conventional methods are not possible, and dorsalis pedis artery or radial artery in case of revascularization.
