Normal involution runs to a timetable precise enough to predict: to the umbilicus by twelve hours, then about one centimetre — one fingerbreadth — a day. Drive the clock and watch the fundus descend, then document what you actually palpated in U/1 notation and let the bench tell you whether it fits. Read a lochia pattern, weigh the loss instead of guessing at it, and plan a perineum whose comfort measures reverse at the 24-hour mark.
Work the involution up
Palpate with the bladder empty: patient supine, knees flexed, lower hand splinting just above the symphysis, upper hand palpating the fundus.
Quantitative blood loss weighs what the blood soaked into and subtracts the known dry weight. 1 gram equals 1 millilitre. Enter what is on the scale.
