For physiological criteria (HR, heart rate; Sao2, oxygen saturation) and crying times (DFC, duration of first cry; TDC, total duration of crying), phase 1 = pre-procedure phase, phase 2 = procedure phase, and phase 3 = post-procedure phase. For NFCS (neonatal facial action coding system), phase 1 = 30 seconds before hand holding, phase 2 = hand holding to needle insertion, and phase 3 = 30 seconds from needle insertion. AA and DF refer to individual authors. S25,25% sucrose solution; placebo, water. | ||||||
