研究背景:早產兒因合併症以及口腔運動系統的不成熟,管灌飲食是常見的腸道營養給予方式,當歷經管灌期,在達到獨立經口進食以完成整個腸道餵食歷程前,早產兒開始經口進食是一關鍵因素,除了受到早產兒本身的因素亦受到環境相關因素影響,大部分的研究以單一地區的早產兒為樣本且主要以獨立經口進食之妊娠週數(postmenstrual age, PMA)為結果變項,鮮少探討不同醫院對早產兒腸道餵食歷程的影響以及護理人員對早產兒腸道餵食歷程主觀做法的相關文獻。
研究目的:了解國內南北兩家醫學中心新生兒加護病房早產兒腸道餵食歷程臨床現況分佈情形以及護理人員臨床照護現況情形及差異,並進一步探討早產兒腸道餵食歷程之影響因素。
研究方法:採相關鑲嵌式混合研究方法進行研究,採用量性及質性方法收集資料。研究場域為南北兩家醫學中心之新生兒加護病房,研究對象包含早產兒及護理人員。早產兒部分,採立意取樣,以病歷回顧的方式收集出生週數小於33週或出生體重小於1500公克早產兒之人口學變項及腸道餵食歷程等相關資料。護理人員量性資料收集部分,採立意取樣,以「護理師發展性照護能力量表」加上研究者所擬題項收集護理人員發展性照護及協助早產兒經口進食策略之能力。質性資料之收集則採分層隨機抽樣,以半結構式訪談大綱收集護理人員對早產兒腸道餵食歷程之照護策略,將收集到的文本以內容分析法進行各主題之次數計算,之後整合早產兒及護理人員之資料,探究及分析兩研究結果是否吻合並進行結果的詮釋及比較。
研究結果:本研究收集達獨立經口進食之早產兒共104位,包括72位(69.2%)南部及32位(31.8%)北部早產兒,兩家醫院早產兒基本人口學等基本屬性無統計上顯著差異(p>0.05)。南部較北部早產兒於「開始腸道營養PMA」(29.4±2.5 vs 31.0±2.6週,p<0.01)、「獨立經口進食PMA」(35.0±1.8 vs 36.6±3.1週,p=0.01)以及「餵食轉換期」(13.6±8.3 vs 22.0±17.2天,p=0.01)早達成且餵食轉換期間體重增加變化趨勢(24.1±10.7 vs 19.1±11.8公克,p=0.03)也較多,且均達統計上顯著差異。兩家醫學中心護理師基本人口學等基本屬性及「護理師發展性照護能力量表」得分無統計上顯著差異(p>0.05),協助早產兒經口進食策略上,北部護理師給予早產兒口腔刺激的餵食策略分數(3.09±0.82 vs 2.72±0.72, p=0.03)以及常規照會復健師的照護策略比例(p=0.01)均較南部護理師高,並達統計上顯著差異;南部護理師給予早產兒非營養性吸吮的餵食策略分數(3.90±0.31 vs 3.60±0.65, p=0.01)以及奶瓶餵食過程中採半高姿位(p<0.01)姿勢較北部護理師多,並達統計上顯著差異。進一步以混合線性模型檢定結果顯示出生週數、出生體重、開始經口進食PMA 及肺支氣管發育不良等因素影響腸道餵食歷程時間,且有統計上顯著差異。醫院別對獨立經口進食PMA及餵食轉換期的影響有統計上顯著差異且開始經口進食PMA對獨立經口進食PMA的影響亦有統計上顯著差異。
結論/實務應用:醫院別影響早產兒達到獨立經口進食PMA及餵食轉換期,獨立經口進食PMA又受到早產兒開始經口進食PMA的影響。早產兒開始經口進食的時機由臨床護理人員被動式的給予,因此當護理人員具有良好發展性照護並運用相關照護策略可以協助早產兒渡過餵食轉換期進而盡早達到獨立經口進食及完成腸道餵食歷程的任務。
Background: Enteral feeding progression includes both enteral and oral feeding milestones. Empirically derived guidelines for starting or progressing oral feeds are not available. Currently, rarely relevant studies are exploring the enteral feeding progression of preterm infants in different regions, and there is a lack of related subjective practices of clinical medical staff members on enteral feeding progression. Purposes: This study aims to understand the current clinical distribution of the enteral feeding progression of preterm infants and the clinical care feeding strategies of the nursing staff members in the neonatal intensive care units at two medical centers in Southern and Northern Taiwan. Furthermore, this study explores the influencing factors of enteral feeding progression in preterm infants. Methods: An embedded correlational mixed-method was conducted at two medical centers in Southern and Northern Taiwan. It includes a retrospective medical chart review for preterm infants’ enteral feeding progression, and we use the developmental support competency scale for nurses (DSCS-N) with self-proposed items and a semi-structured interview guide to evaluate NICU nurses’ ability on the developmental care of enteral feeding progression. Results: The “PMA of starting nutritional feeds”, the “PMA of full oral feeding”, and the “transitional feeding period” in preterm infants of the southern medical center were reached early, and the trend of weight gain during the “transitional feeding period” in preterm infants of the southern medical center also increased more than those of the northern one. Regarding the scores of feeding strategy “oral stimulus” for preterm infants and the proportion of the “consultation of rehabilitation routinely”, the northern nurses’ scores were higher than those of the southern nurses. Regarding the scores of feeding strategy of “providing nonnutritive sucking” for preterm infants and the proportion of the ”semielevated side-lying” posture during feeding, the southern nurses scores’ were higher than those of the northern nurses. Furthermore, the results of the mixed effect model showed that factors of the “PMA of the first date of oral feeding” affected the time of enteral feeding progression. Conclusion: Nursing staff members need to have good developmental care knowledge and use relevant feeding strategies to help preterm infants passing the transitional feeding period to complete the tasks of enteral feeding progression as soon as possible.
