The changes in body position can cause changes in lung function, and it is necessary to understand them, especially in the postoperative upper abdominal surgery, since these patients are susceptible to postoperative pulmonary complications.
To assess the vital capacity in the supine position (head at 0° and 45°), sitting and standing positions in patients in the postoperative upper abdominal surgery.
A cross-sectional study conducted between August 2008 and January 2009 in a hospital in Salvador/BA. The instrument used to measure vital capacity was analogic spirometer, the choice of the sequence of positions followed a random order obtained from the draw of the four positions. Secondary data were collected from the medical records of each patient.
The sample consisted of 30 subjects with a mean age of 45.2 ± 11.2 years, BMI 20.2 ± 1.0 kg/m(2). The position on orthostasis showed higher values of vital capacity regarding standing (mean change: 0.15 ± 0.03 L; p=0.001), the supine to 45 (average difference: 0.32 ± 0.04 L; p = 0.001) and 0° (0.50 ± 0.05 L; p = 0.001). There was a positive trend between the values of forced vital capacity supine to upright posture (1.68 ± 0.47; 1.86 ± 0.48; 2.02 ± 0.48 and 2.18 ± 0.52 L; respectively).
Body position affects the values of vital capacity in patients in the postoperative upper abdominal surgery, increasing in postures where the chest is vertical.
体位改变会导致肺功能变化，有必要对此加以了解，尤其是在上腹部手术后的患者中，因为这些患者易发生术后肺部并发症。
评估上腹部手术后患者在仰卧位（头部呈0°和45°）、坐位和站立位时的肺活量。
2008年8月至2009年1月在萨尔瓦多/巴伊亚州的一家医院进行了一项横断面研究。用于测量肺活量的仪器是模拟肺活量计，体位顺序的选择遵循从四个体位抽签获得的随机顺序。从每位患者的病历中收集二级数据。
样本包括30名受试者，平均年龄为45.2±11.2岁，体重指数为20.2±1.0kg/m²。直立位时的肺活量在站立位时显示出更高的值（平均变化：0.15±0.03L；p=0.001），仰卧位到45°（平均差异：0.32±0.04L；p=0.001）和0°（0.50±0.05L；p=0.001）。从仰卧位到直立位的用力肺活量值之间存在正趋势（分别为1.68±0.47；1.86±0.48；2.02±0.48和2.18±0.52L）。
体位影响上腹部手术后患者的肺活量值，在胸部垂直的体位时增加。
