20 randomly selected infants of 33 weeks gestation and under at birth were allowed to go home from the neonatal unit provided they were clinically well and had passed the nadir of their postnatal weight-loss and provided home conditions were satisfactory. Weight-gain at home was satisfactory and there was no increased rate of hospital readmission compared with 20 randomly selected pre-term infants who were discharged at a more traditional weight of 2200 g. There is therefore little justification for the widespread practice in Britain of delaying discharge of preterm infants until they reach a predetermined weight (usually 2000--2500 g).
随机挑选出20名出生时孕周为33周及以下的婴儿，只要他们临床状况良好，已度过出生后体重下降的最低点，且家庭条件令人满意，就允许他们从新生儿病房出院回家。这些婴儿在家中的体重增加情况令人满意，与20名随机挑选的、以更传统的2200克体重出院的早产儿相比，再次入院率并没有增加。因此，在英国，普遍将早产儿出院时间推迟到他们达到预定体重（通常为2000 - 2500克）的做法几乎没有道理。
