Colorectal cancer is a common digestive tract tumor in China. At present, laparoscopic surgery has become the classic operation of colorectal cancer surgery compared with the traditional open abdominal surgery. Although laparoscopic surgery has many advantages, such as less pain, faster recovery and so on. However, relevant studies have shown that postoperative pulmonary complications are more common in patients undergoing Laparoscopic Colorectal Surgery, which contribute to significant increases in morbidity, mortality, length of postoperative hospital stay and medical consumption. The incidence of pulmonary complications after abdominal surgery has been reported to be between 9% and 40%. The reduction in pulmonary volume and respiratory muscular activation after major abdominal surgery due to surgery-related shallow breathing, pain, long-term bed rest, mucociliary clearance disorder, and diaphragmatic dysfunction may be the main causes of postoperative pulmonary complications. Numerous studies have demonstrated physiological improvement related to prone positioning. Prone positioning consists of placing a patient face down. Prone positioning has been used for to improve oxygenation in patients who require invasive mechanical ventilation for acute respiratory distress syndrome (ARDS). It has also been applied to non-intubated patients with acute respiratory failure (ARF), to improve oxygenation and delay or even avoid the need for invasive ventilation. So, the purpose of this study is to observe whether preoperative prone position training can reduce the incidence of pulmonary complications after laparoscopic colorectal cancer surgery.
