A new portable, cheap and indigenous incubator made of polystyrene has been devised for delivery of primary health care services to the newborn babies in the community. Twenty six babies with a mean weight of 1726 g (range 1388-1981g) and gestational age of 35.3 weeks (range 34-38 wks) were continuously evaluated for 2 hours observation period, in naked and clothed conditions. Rectal, abdominal skin, foot, ambient air and nursery temperatures were recorded. The baseline core temperature of the babies was 36.58 (+/- 0.21) degrees C; after incubator care it was recorded s 36.80 (+/- 0.10) degrees C in naked infants. The baseline core temperature of the clothed babies was 36.63 (+/- 0.21) while it was 37.01 (+/- 0.18) after 2 hours of incubator care. An ambient air temperature of 33-34 degrees C in the incubator (thermoneutral temperature range for these babies being 31.0-33.8 degrees C) was achieved within 30-60 minutes of incubator stay (nursery temperature being 28 +/- 0.6 degrees C). No evidence of carbon dioxide narcosis, hypoxia, acidosis, or adverse thermoregulatory behavior was observed. One baby had hypoglycemia (blood sugar less than 35 mg/dl) and another had sweating. There is a scope for providing additional facilities like administration of oxygen, phototherapy, X-rays through the incubator without disturbing the baby.
一种新型的便携式、廉价且国产的聚苯乙烯制成的婴儿培养箱已被设计出来,用于向社区中的新生儿提供初级卫生保健服务。对26名平均体重为1726克(范围1388 - 1981克)、胎龄为35.3周(范围34 - 38周)的婴儿在裸体和穿衣条件下进行了2小时的连续观察评估。记录了直肠、腹部皮肤、足部、环境空气和育婴室温度。婴儿的基线核心温度为36.58(±0.21)摄氏度;在培养箱护理后,裸体婴儿的核心温度记录为36.80(±0.10)摄氏度。穿衣婴儿的基线核心温度为36.63(±0.21),而在培养箱护理2小时后为37.01(±0.18)。在培养箱中停留30 - 60分钟内(育婴室温度为28 ± 0.6摄氏度),实现了培养箱内33 - 34摄氏度的环境空气温度(这些婴儿的中性温度范围为31.0 - 33.8摄氏度)。未观察到二氧化碳中毒、缺氧、酸中毒或不良体温调节行为的证据。一名婴儿出现低血糖(血糖低于35毫克/分升),另一名婴儿出汗。通过培养箱提供额外设施如输氧、光疗、X射线检查等而不打扰婴儿是可行的。
