Table: Heart rate, parasympathetic and sympathetic activity values (mean ± standard deviation) of the surgeon in office day and during DIEP.
Figure: The course of heart rate (HR), parasympathetic activity (PSA, measured as HF) and sympathetic activity (SA, measured as LF/HF) of the surgeon during DIEP and office day. I; dissection of the flap and the perforator. II; dissection of the internal mammary vessels and final steps of perforator dissection after lunch. III; preparation of the recipient and donor vessels for anastomosis. IV; vein anastomosis. V; artery anastomosis. VI; shaping of the flap.
