Pulmonary Complication

The objective of this study was to investigate the difference in postoperative pulmonary complications (PPCs) between spinal anesthesia and general anesthesia in patients undergoing delayed hip surgery.

The aim of this study is to determine if lung ultrasound score has a strong predictive value for post operative pulmonary complications in living liver transplant recipient

Postoperative pulmonary complications (PPCs) are common in children undergoing general anesthesia and are associated with prolonged stay in the hospital and high costs. Development of PPCs is associated with ventilator settings in adult patients undergoing general anesthesia. Data on perioperative ventilator settings in children are lacking, leaving the anaesthetist without guidance. Consequently, the current standard of care in perioperative mechanical ventilation in children is expected to be extremely heterogeneous, leading to ventilation with higher levels of energy than necessary. Therefore, it is highly necessary to evaluate the current practice in perioperative ventilation in children and to determine associations with PPCs.

The goal of this multicenter randomized controlled trial is to explore the efficacy of perioperative oral decontamination and immunonutrition supplement to prevent postoperative pulmonary complications in elderly patients(≥65 years) receiving elective non-cardiac operations. Participants will be either given immunonutrition supplement versus routine nutrition advice, and oral chlorhexidine decontamination versus routine oral care randomly. The two interventions will be compared with control groups separately regarding postoperative pulmonary complications and other outcomes.

Postoperative pulmonary complications are serious threat to surgical patients, especially to high-risk geriatric patients. There is evidence that laryngeal mask airway is associated with postoperative pulmonary complications in comparison with tracheal intubation. However, conclusion may reverse among frail population such as high-risk geriatric patients. Geriatric patients are often associated with loose mask seal due to physiological changes, which may increase chances of aspiration and pose challenges to intraoperative airway maintenance. It was reported that laryngeal mask airway causes more atelectasis among children, but no report among high-risk elderly. The investigators therefore propose this study to verify the non-inferior effect of laryngeal mask airway compared to tracheal intubation on postoperative pulmonary complications among high-risk geriatric patients undergoing elective non-cardiothoracic surgeries.
