The majority of infants with congenital talipes equinovarus (CTEV) require tenotomy of the tendoachilles. The pain response of this procedure in the awake infant has not been previously reported. In this observational study, multimodal pain management strategies, including oral sucrose, oral paracetamol, topical anesthetic, local anesthetic, a pacifier (dummy), and swaddling, were used. Physiological responses and pain were recorded. Pain was rated out of 10 at regular intervals, using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale. Ninety-one infants (65 men, mean age = 53 days, range = 19-217 days) were observed. At baseline, median FLACC, heart rate (HR), and oxygen saturation (Spo2) were 1, 159, and 97% respectively. Peak median FLACC and HR were 9 and 200, respectively, and lowest median Spo2 was 92%. The median (interquartile range) time for FLACC to return to 3 or less was 2 (2-5) minutes. Achilles tenotomy for CTEV in the awake infant is associated with high pain levels despite provision of multimodal pain relief measures.
