心臟手術前病人不確定感及控握信念對術後復原之影響

Uncertainty, Health Locus of Control and Recovery in Patients With Heart Surgery

指導教授 : 賴裕和

摘要


心臟血管疾病為國人常見且嚴重的疾病,心臟手術成為極普遍的外科治療方式,手術後的復原進展順利,是所有醫護人員的期盼與職責所在。面對心臟重大手術,易使病患產生不確定感,健康控握信念人格特質可以用來預測個體健康行為表現。本研究目的在探討心臟手術病人之人口學特質、疾病及治療特質、不確定感及健康控握信念對手術後復原的影響,探討手術後重要復原指標(疼痛、睡眠、疲憊、誘導式深呼吸訓練器吸氣量、六分鐘走路距離)的預測因素。本研究為描述與推論性的小型縱貫性研究,以立意取樣方式選擇在北部某醫學中心接受經胸骨切開執行心臟手術病人53位為研究對象。以皮爾森相關性分析、t檢定、變異數分析等統計方法,分析手術後重要復原指標的影響因素,再將統計上達顯著意義的影響因素,放入逐步回歸分析中找出顯著預測因子,研究結果如下:「術後第7天最痛程度」越高者,與未婚、曾有心臟手術病史、手術前一週有心絞痛、手術前體能狀況較差、不確定感總分較高、機運健康控握傾向、手術後一週內睡眠干擾較嚴重者,有統計上顯著相關或差異;將影響因素放入迴歸分析中發現,不確定感總分、是否已婚為顯著預測因子,可解釋變異量42.6%。「睡眠干擾」越嚴重者,與右肋膜胸管留置天數越長、手術後第1、4、7天最痛程度越高、不確定感程度越高者,有統計上顯著相關;放入迴歸分析發現,術後第4天最痛程度、不確定感總分為顯著預測因子,可解釋變異量35.1%。「疲憊」嚴重度越高者,與心臟胸管留置天數越長、不確定感程度越高者,有統計上顯著相關;不確定感總分為顯著預測因子,可解釋變異量39.2%。在體能狀況復原進展方面,「術後第七天誘導式深呼吸訓練器吸氣量」越低者,與實際年齡越長、實際教育年數越少、術前誘導式深呼吸訓練器吸氣量越低、心臟胸管留置天數越長、手術前不確定感程度越高、機運健康控握傾向、術後一週內睡眠干擾越嚴重、術後一週內疲憊程度越高者,有統計上顯著相關或差異;進入迴歸分析發現,術前誘導式深呼吸訓練器吸氣量、術後一週內疲憊程度為顯著預測因子,可解釋總變異量61.2%。「術後第七天六分鐘走路測試行走距離」越短者,與術前心臟LVEF越差、心臟胸管留置天數越長、手術前一週有心絞痛、不確定感程度越高、機運健康控握傾向、術後第7天最痛程度越高、術後一週內睡眠干擾越嚴重、術後一週內疲憊程度越高者,有統計上顯著相關或差異;進入迴歸分析發現術後一週內疲憊程度、手術前六分鐘走路測試行走距離、不確定感總分為顯著預測因子,可解釋變異量78.1%。

The impact from cardiac surgery might lead high level of uncertainty on patients. The purpose of this study is to examine patients’ recovery outcomes and its related factors in patients receiving cardiac surgery. The post-operative recovery outcomes included pain intensity, sleep, fatigue, deep-inspiration hold volume and 6 minutes walk distance. Factors used to predict these recovery outcomes were LVEF, EuroScore, health locus of control, and uncertainty. Data were collected from interviewing patients receiving cardiac surgery in two time points: pre-operation and 7 days post-operation. In addition to the original data collection time points, pain was also further assessed in 1st and 4th post-operation. A total of 53 subjects were recruited from a medical center in Northern Taiwan. The major findings showed that patients with higher uncertainty had higher fatigue level, more sleep disturbance, more pain in the 7th day post-operation and less 6-minute walking distance. Patients with more fatigue had lower deep-inspiration hold volume and less 6-minute walking distance in the 7th days post-operation. Patients with higher deep-inspiration hold volume before surgery and less fatigue during one week of surgery could predict higher post-operative deep-inspiration hold volume. The major results suggested that uncertainty plays an important role in the recovery for patients receiving cardiac surgery. Nursing intervention to support patients decreasing their pre-operative uncertainty may enhance patients’ recovery and should be further tested in the future study.
