To investigate how suturing orange and banana peels, pig skin, and synthetic skin compares with the experience of suturing human skin.
Interventional study of simple interrupted, vertical mattress, and subcuticular suturing on the four test materials.
PARTICIPANTS, SETTING: Fifteen consultants and six trainees in surgical and emergency medicine specialties at a New South Wales regional teaching hospital.
The primary outcome was completion of simple interrupted, vertical mattress, and subcutaneous sutures. Secondary outcomes (assessed in a questionnaire) were similarity of suturing each material to suturing human skin, suitability of each material for practising each suture type, and similarity of each material to human anatomic skin types.
All 21 participants completed simple interrupted sutures in bananas and pig and synthetic skins, and 15 in orange skin (P = 0.002). All 21 participants completed vertical mattress sutures in pig and synthetic skins, 18 in bananas, and six in oranges (P < 0.001). The numbers of completed subcuticular sutures were lower for the two fruits (orange, zero; banana, two) than for pig and synthetic skins (each, 21; P < 0.001). Banana peel was rated as somewhat similar to human skin and recommended for practising simple interrupted and vertical mattress suturing.
Bananas are not only useful as healthy snacks between theatre cases, but also for practising and improving simple and vertical mattress suturing skills. However, less portable and nourishing materials are required for subcuticular suturing practice, such as pig skin or synthetic skin.
研究缝合橙皮和香蕉皮、猪皮和合成皮与缝合人皮的体验有何不同。
在四种测试材料上进行简单间断、垂直褥式和皮下缝合的干预性研究。
参与者、设置：新南威尔士州地区教学医院的 15 名外科和急诊医学顾问和 6 名学员。
主要结局是完成简单间断、垂直褥式和皮下缝合。次要结局（通过问卷调查评估）是缝合每种材料与缝合人皮的相似性、每种材料对练习每种缝合类型的适宜性以及每种材料与人解剖皮肤类型的相似性。
所有 21 名参与者均完成了香蕉、猪皮和合成皮上的简单间断缝合，15 名参与者完成了橙子皮上的简单间断缝合（P=0.002）。所有 21 名参与者均完成了猪皮和合成皮上的垂直褥式缝合，18 名参与者完成了香蕉皮上的垂直褥式缝合，6 名参与者完成了橙子皮上的垂直褥式缝合（P<0.001）。两种水果（橙子，零；香蕉，两）上完成的皮下缝合数量低于猪皮和合成皮（各 21；P<0.001）。香蕉皮被评为与人体皮肤有些相似，并推荐用于练习简单间断和垂直褥式缝合。
香蕉不仅是手术间隙的健康零食，还可用于练习和提高简单和垂直褥式缝合技术。然而，对于皮下缝合练习，需要更便携和营养的材料，如猪皮或合成皮。
