早产儿吸氧副作用不可忽视

早产儿吸氧副作用不可忽视早产儿的身体素质比足月儿相差很多，很多早产儿出生后会被安排吸氧，氧气对于挽救早产儿的性命极为重要，但是吸氧也是有一定的副作用的，性命我们就为家长朋友们介绍一下吸氧对宝宝的副作用。

早产儿吸氧副作用不可忽视有关资料表明，早产儿吸氧并发视网膜病变的几率为15%至30%，虽然并非完全因吸氧引起，但家长一定要警惕，避免高浓度、长时间吸氧。

视网膜病变初期，患儿的外观基本正常，不易被家长察觉，容易使人麻痹大意。

早产儿视网膜病变的病程通常分为五期，在第一期、第二期时，病变有一部分可自愈;到第四期则很严重，虽然可进行手术治疗，但效果较差。

如果发展到第五期，则有极大的危险致终身失明。

需要提醒家长的是，从三期到四期病情变化非常快，只有短短的数天，加上婴儿的眼睛从外观看来没有异常，因此很容易错过。

一旦错过最佳治疗时机，婴儿很可能失明，所以孩子一旦有视网膜病变迹象，要密切监测病程发展，以便及时治疗。

专家建议：对于出生体重在1500克以下或胎龄在28周以内的，出生后曾接受过长期吸氧的婴儿，家长应在孩子出生4周内及时带孩子到专业的眼科医院进行检查，以便早期发现，及时治疗视网膜病变的问题。

如遇到早产儿或低体重儿出生后因血管发育不完全而出现呼吸窘迫的情况，的确需要人工吸氧。

可以说人工吸氧已成为了抢救早产儿生命不可缺少的手段。

但即使氧气能将早产儿从危重的病情中抢救过来，我们也需要警惕若给早产儿吸入高浓度氧气，或用氧时间过长，会使早产宝宝患上视网膜病变。

这是因为早产宝宝视网膜本身发育不完全，高浓度氧气刺激视网膜组织，使视网膜血管的正常发育受到干扰，从而产生病变。

一般在出生后一个月左右出现，常为两侧，男女发病率相等。

故此在给早产儿进行吸氧治疗时，医生一般会控制氧气浓度，使其在40%以下，并且时间也不宜过长。

此外，家长还需定期带早产宝宝到医院做眼科检查，密切监测病程发展，一旦发现宝宝有视网膜病变迹象，应及时到医院检查治疗，若是错过最佳治疗时机，或将导致婴儿失明。

出生4周及时检查专家指出，氧气对于抢救新生儿生命作用关键，所以其使用不可避免。

对于有过吸氧治疗史的新生儿，家长要尽早带孩子到眼科进行检查，以便早期发现和治疗视网膜病变。

出生体重在1500克以下或胎龄在28周以内的婴儿、体重及胎龄正常，但出生后接受过吸氧的婴儿，都应该及时进行视网膜检查。

而检查的时间为出生后4周，或从母亲怀孕后32周时开始检查，这样可以及时发现和筛查婴儿的视网膜病变并及时治疗。

一定要去正规的眼科找有资质的医生，他们用间接眼底镜或眼底数码相机可以捕捉到婴儿是否视网膜病变。

通常来说，病变早期若在视网膜的有血管区和无血管区之间出现“分界线”，则是婴儿发生视网膜病变的临床体征。

治疗时机切勿错过虽然得到了及时筛查，但如果错过最佳治疗“时间窗”，婴儿也可能永远生活在黑暗中。

早产儿视网膜病变的病程通常分为五期，在第一期、第二期时，病变有一部分可自愈;到第四期则很严重，虽然可进行手术治疗，但效果不好。

如果发展到第五期，则有极大的危险终身失明。

因此，在病程一至三期时，是治疗早产儿视网膜病变的最佳时间段，尤其第三期是治疗的关键期。

需要提醒家长的是，从三期到四期病情变化非常快，只有短短的数天，加上婴儿的眼睛从外面看来没有异常，因此很容易错过。

一旦错过最佳治疗时机，婴儿很可能失明，所以孩子一旦有视网膜病变迹象，就应该紧密监测病程发展，及时治疗。

Premature infants physical quality than full term differs a lot, a lot of preterm birth will be arranged after oxygen, oxygen is of extreme importance to save the lives of premature infants, but oxygen also has some side effects, life we introduce parents friends oxygen to the baby's side effects.Premature infant oxygen side effects cannot be ignoredRelevant data show that the premature infant oxygen concurrent retinopathy chance of 15% to 30%, while not entirely caused by oxygen, but parents must be vigilant, avoid high-concentration oxygen for a long time. The appearance of the children with early retinopathy, the basic normal, not easy to be parents notice, make people easy to paralysis. Premature retinopathy progression is divided into five periods, usually in the first stage, the second stage, the part of lesion can heal itself; By the fourth period is very serious, although surgery can be performed, but the effect is poor. If the development to the fifth period, have a great danger to lifelong blindness. Need to remind parents, from the three phase to four phase condition changes very fast, only a short few days, with the baby's eyes from seems to be no exception, so it's easy to miss. Once you miss the best treatment time, the baby may be blind, so once the child has a retinopathy signs, to closely monitoring the course of development, in order to timely treatment.Experts advise: the birth weight under 1500 grams or gestational age, within 28 weeks had oxygen for a long time after the birth of baby, parents should take children in time in the child 4 weeks to professional eye hospital inspection, so that early detection and timely treatment of retinopathy.Such as in premature and low birthweight babies born after respiratory distress by vascular incomplete, do need artificial oxygen. Can say artificial oxygen save premature life has become indispensable means.But even if the oxygen can be premature babies from critical illness rescue come over, if we also need to be vigilant to premature inhaling high concentrations of oxygen, oxygen or use time is too long, can make premature babies develop retinopathy. This is because the baby early to produce the retina itself development completely, high concentration of oxygen to stimulate retinal tissue, make the normal development of the retinal blood vessels is disturbed, resulting in a pathological changes. Generally appear in about a month after birth, often for both sides, the men's and women's hair disease rate are equal.Therefore during the oxygen therapy for premature babies, the doctor would control the oxygen concentration, make its below 40%, and the time also shoulds not be too long. In addition, parents also need to regularly took the baby to the hospital to do an eye test, premature close monitoring of disease development, once found the baby signs retinopathy, should be timely to the hospital treatment, if missed the best treatment time, or will lead to blindness, baby.Born 4 weeks check in timeThe expert points out, oxygen function key for rescue neonatal lives, so its use is inevitable. For newborns had a history of oxygen therapy, parents should check with children as early as possible to the eye, so that early detection and treatment of retinopathy.Birth weight under 1500 grams or gestational age infants within 28 weeks, weight and gestational age is normal, but after the birth of babies received oxygen, should be timely examination of the retina. And check for 4 weeks after birth, mother pregnancy after 32 weeks or the start of inspection, so that we can timely detection of retinopathy and screening infants and timely treatment.Must go to normal eye looking for a qualified doctor, they use indirect ophthalmoscope or fundus digital camera can capture the baby whether retinopathy. Generally speaking, if early lesions in retinal vascular area and avascular area between "line", is the baby retinopathy clinical signs.Treatment time don't miss itAlthough got timely screening, but if you miss the best treatment "time window", the baby could live forever in the darkness.Premature retinopathy progression is divided into five periods, usually in the first stage, the second stage, the part of lesion can heal itself; By the fourth period is very serious, although surgery can be performed, but the result is bad. If the development to the fifth period, the great risk of lifelong blindness.Therefore, in the course of one to three period, is the best time for treatment of retinopathy of premature babies, especially the third stage is the critical period of treatment. Need to remind parents, from the three phase to four phase condition changes very fast, only short short several days, with the baby's eyes from the outside it seems no exception, so it's easy to miss. Once you miss the best treatment time, the baby may be blind, so once the child has a retinopathy signs, should be closely monitoring disease development process, the timely treatment.。
