目的:观察不同时机应用GT-4A导乐分娩镇痛仪护理对初产妇分娩的影响。方法:选取2020年6月至2022年6月该院收治的125名初产妇进行前瞻性研究,按照随机数字表法将其分为研究组63例与对照组62例。对照组于产妇宫口开至2~3 cm时应用GT-4A导乐分娩镇痛仪护理,研究组于产妇宫口开至1 cm时应用GT-4A导乐分娩镇痛仪护理。比较两组产程(第一产程、第二产程、第三产程以及总产程)时间、产妇不同时间(第一产程潜伏期末、第一产程活跃期末、第二产程末)疼痛视觉模拟评分法(VAS)评分、自然分娩率和母婴结局[产妇产后2 h出血量、新生儿出生5 min Apgar评分、脉搏血氧饱和度(SpO_(2))]。结果:研究组第一产程、第二产程、第三产程及总产程时间均短于对照组,差异有统计学意义(P<0.05);第一产程潜伏期末、第一产程活跃期末、第二产程末,研究组产妇VAS评分均低于对照组,差异有统计学意义(P<0.05);研究组自然分娩率为71.43%,高于对照组的53.23%,差异有统计学意义(P<0.05);研究组产后2 h出血量少于对照组,差异有统计学意义(P<0.05);研究组新生儿出生5 min Apgar评分、SpO_(2)水平均高于对照组,差异有统计学意义(P<0.05)。结论:初产妇宫口开至1 cm时应用GT-4A导乐分娩镇痛仪护理可缩短产程时间,提高自然分娩率,降低VAS评分,以及改善母婴结局,效果优于初产妇宫口开至2~3 cm时应用。
