使用維生素C能促進傷口癒合

長期臥床的病人所產生的壓力性損傷（pressure injury），其整體營養的表現，是影響壓力性損傷預後很重要的原因之一。呼吸照護病房（Respiratory Care Ward）病人屬性需終生依賴呼吸器，多數為長期臥床，且生理照顧皆全數由醫護人員協助，一旦發生壓力性損傷，除了給予傷口護理或是外科清創之外，其營養需求會比正常人高許多，包括熱量、蛋白質、維生素及礦物質等，營養補充是相當重要的。維生素C在許多臨床研究上有證實確實能夠改善傷口癒合，且價格便宜。所以，如果有經濟實惠又能改善傷口的營養輔助品對於患者及其家屬都是一種福音。本研究是經由實證過程，搜尋與評讀出最佳證據之結果為提供維生素C的選擇，能使有3級（含）以上的壓力性損傷的患者傷口面積縮小，進而降低護理時數、減少敷料成本與傷口護理費用。

Pressure injury caused by long-term bedridden patients can affect wound healing through nutritional support. Patients in the Respiratory Care Ward need to rely on respirators for life, most of them are bedridden for a long time, and their physiological care is assisted by medical staff. In the event of a pressure injury, in addition to wound care or wound debridement, nutritional needs will be higher, including calories, protein, vitamins, and minerals. The nutrition supplements are very important. Vitamin C has been shown to promote wound healing and is inexpensive. Economically and wound healing, it is beneficial to patients and their families. Through the evidence-based medicine, the result of searching and evaluating the best evidence is that the choice of providing vitamin C can reduce the wound area of patients with pressure injuries of grade 3 (inclusive) or higher, thereby reducing the number of nursing hours, dressing and wound care costs.
