RESUMO
Objective To compare effect of swaddle bathing and tub bathing on neonatal behavior state, and improve the safety and comfort of newborn infants. Methods This was a prospective non-randomized control study. From February 2016 to September 2017, a total of 110 neonates were divided into swaddle bathing group or tub bathing group, each group including 55 cases. Neonates in swaddle bathing group received swaddle bathing after discharge, while neonates in tub bathing group received tub bathing. Behavior state in the process of bathing and temperature before and after bathing were compared. Results In swaddle bathing group, 85.5％ (47/55) of neonates kept quiet during the bathing process, which was significantly higher than 56.4％(31/55) in the tub bathing group (χ2=11.282, P<0.01). 30.9％(17/55) of neonates in swaddle group were crying, significantly lower than 50.9％ (28/55) in tub bathing group (χ2=4.550, P<0.05). Duration of neonatal grasp reflex, crying time (seconds), and neonatal body temperature after bathing was (2.3±0.4) points,2(0,7)s and (36.49±0.02)℃in swaddle bathing group, and (7.9±0.5) points, 6 (5,10) s and (36.38±0.03)℃in tub bathing group, and the difference was significant(t=4.366, 2.910, Z=3.534, P<0.01). Conclusions Swaddle bathing can promote neonatal behavior state in the process of bathing and reduce neonatal the feeling of fear. Moreover, it could help keep warm more effectively.
RESUMO
Objective:Contrast sensitivity(CS) is a new technique which measures the discrimination capacity of the human eye to an object under low contrast conditions.It is more acute and more complete in reflecting visual function than the Snellen chart which is used to test the discrimination under high contrast conditions.Our purpose is to compare the effect of an aspheric intraocular lens(IOL) with those of conventional monofocal silicone and acrylic IOL and multifocal IOL on functional visual performance. Methods:To 90 eyes after phaco emulsification with IOL implantation,30 eyes of age-matched patients were selected as control,all patients were 50-80 years old,with no disorders,other than cataract,known to affect CS.Corrected visions were all over 0.8.The CS was measured 30 days after surgery.Results:After surgery the patients' CS returned to the normal level,but which was lower than that of the control's.The aspheric IOL provided statistically significant better contrast sensitivity at 6,12 and 18 cycles per degree. Conclusion:The use of a modified prolate IOL in cataract surgery has the potential to improve CS,which is designed to partially compensate the average spherical aberration of the cornea.
RESUMO
Objective: To evaluate the curative effect of the amblyopia therapeutic instrument and to search for a best treatment of amblyopia for pre-school children.Methods: One hundred and seven children with amblyopia were treated by the amblyopia therapeutic instrument and followed up, and the curative effects were analyzed.Results: The curative effects were significantty different between the group treeted with the instrument and those treated otherwise.Conclusion: The amblyopia therapeutic instrument is a satisfactorily effective option for the treatment of amblyopia in pre-school children.
RESUMO
Objective:To study analyze sthe contrast sensitivity of high myopia.Methods:The contrast sensitivity function(CSF) in 60 eyes of 30 patients with high myopia was studied with normal subjects as control.Those with other ocular disease or systemic disease were excluded to avoid any possible affection.The patients were aged from 12 to 62 years.Corrected vision were all over 0.8 in high myopia,and the control was more than 1.0.The contrast sensitivity function was measured with CSV-1000E Vision Testing Instrument(provided by VECTOR VISION company).Results:The results revealed that the CSF of high myopia in each space-frequency range was decreased.The difference between high myopia group and control group was significant(P
