ABSTRACT
Objective:To explore the effect of kangaroo mother care (KMC) on lactation, uterine involution of parturients and neonatal pain.Methods:A total of 200 parturients who gave birth at full term in our hospital from January 2019 to June 2019 and their newborns were selected as the research objects, they were randomly divided into control group and observation group of 100 pairs each. The control group received routine obstetric postpartum care and the observation group received KMC. The KMC cognition, postpartum lactation and uterine involution, neonatal pain during neonatal heel blood collection were compared between the two groups.Results:The cognition of KMC in the observation group was significantly better than that in the control group, and the difference was statistically significant ( χ 2 value was 24.700, P<0.01). The first lactation time of parturients in the observation group was (41.25±3.20) hours after birth, which was earlier than (54.17±2.20) hours in the control group, there was significant difference between the two groups ( t value was 2.378, P value was 0.019). The breast pain Ⅰ degree (20 cases), Ⅱ degree (56 cases), Ⅲ degree (24 cases) in observation group were significantly lighter than those in control group (62, 27, 11 cases respectively) 72h after delivery, the differences were statistically significant ( t value was 12.166, P value was 0.011). The parturients of sufficient lactation in the observation group (73 cases) were more than those in the control group (34 case),the differences was statistically significant ( χ 2 value was 30.570, P value was 0.000). The uterine fundus of the observation group decreased by (3.06±1.26) cm and (1.67 ±0.43) cm at 24h and 48h postnatally, which were better than those of the control group (1.97±0.92) cm and (1.23±0.18) cm,the differences were statistically significant ( t value was 3.162, P value was 0.002; t value was 2.689, P value was 0.009). In the process of heel blood collection after 72h of delivery in both groups, the pain scores of the observation group during and after blood collection were 4.92±0.33 and 2.37±1.27 respectively, which were lower than those of the control group (5.57±1.37 and 5.01±1.09), and the differences were statistically significant ( t value was 2.035, P value was 0.046; t value was 2.579, P value was 0.011). The heart rates of the observation group during and after blood collection were (121.36±22.13) and (142.55±23.91) beats/min, respectively, which were lower than (152.64±18.21) and (156.79±17.37) beats/min of the control group, the difference were statistically significant ( t value was 2.375, P value was 0.018; t value was 2.126, P value was 0.037). The blood oxygen saturation of the observation group during and after blood collection were 0.967 2±0.013 7 and 0.985 5 ±0.022 4 respectively, which were significantly higher than 0.891 7±0.116 5 and 0.914 5±0.137 8 of the control group ( t value was 2.036, P value was 0.046; t value was 2.017, P value was 0.047). Conclusions:The implementation of KMC can promote lactation, accelerate uterine involution, and relieve the pain of neonats during neonatal heel blood collection; Strengthening the health education of KMC can improve the cognition of parturients and their families about KMC, which has positive significance in promoting maternal and infant health and is worthy of clinical application.
ABSTRACT
@#ObjectiveTo investigate the diagnostic value of mini peak flow meters in cough variant asthma (CVA). Methods131 patients with the main symptom of chronic cough whose chest X-ray showed normal were included in this study. The peak expiratory flow (PEF) rate of each patient was measured by mini peak flow meters during the bronchial dilation test, and the results were analyzed. ResultsThe rate of positive reaction in the test was 33.6% (44/131), of whom 40.9% (18/44) were delayed over 1 year. 16.8% (22/131) of all the patients' PEF increased 10% to 15% in after the test. ConclusionMini peak flow meters can be used in the diagnosis of CVA.
