Active clinical trials for "Postoperative Complications"

A cardiopulmonary exercise test (CPET) is increasingly used for preoperative risk assessment. Oxygen uptake (VO2) at peak exercise (VO2peak) and VO2 at the ventilatory anaerobic threshold (VO2VAT) are the most commonly used preoperative CPET variables that are associated with postoperative outcomes following colorectal cancer surgery. The aim of this study is to investigate the association between preoperative submaximal and effort-independent CPET variables and postoperative outcomes in colorectal cancer surgery. Specifically, the slope of the relation between minute ventilation and carbon dioxide production (VE/VCO2-slope) and the oxygen uptake efficiency slope (OUES) will be investigated.

To test the hypothesis that nebulized Pulmicort Respules could reduce post operation pulmonary complication incidence in primary lung cancer patients with COPD. Compare post-operation pulmonary complication incidence in two treatment arms among primary lung cancer patients with COPD required single lobectomy from 3days before operation to 7 days after operation.

Pre- and postoperatively patients who underwent free fibula flap were examined regarding donor-site morbidity of the lower extremities.

An observational trial aiming to verify whether does any relationship exist between renal resistive index and postoperative outcome in major high risk surgery

The investigator evaluated diaphragmatic function in patients undergoing thoracic surgery. Diaphragmatic displacement was evaluated before surgery, 2 and 24 hours after surgery. Also, preoperative spirometry and postoperative spirometry were collected (24 hours after surgery).

During robotic laparoscopic surgery, a high intraperitoneal pressure may result in high airway pressure and inadequate perfusion of the abdominal organs, and as a result the postoperative outcomes. Degree of neuromuscular blockade (NMB) can affect the intraperitoneal pressure. In this study, the patients undergoing robotic laparoscopic surgery will be assigned to deep NMB group and moderate NMB group. Perioperative outcomes including maximal intraperitoneal pressure, maximal intraoptic pressure, quality of emergence, postoperative pain, and incidence of postoperative respiratory complication will be compared. The results of this study will provide evidence for optimizing NMB protocol of robotic laparoscopic surgery.

The aim of this study is to investigate the hypothesis that single dose of tranexamic acid (TXA) preoperatively will lower blood loss and transfusion rate in elderly patients with hip fractures (intertrochanteric or Subcapital), that will be treated with intramedullary nailing and cemented hemiarthroplasty respectively. After application of inclusion and exclusion criteria, patients will be randomized in two groups. Group 1 will include patients that receive preoperatively single dose of TXA (15mg/kg) and Group 2 will include patients that receive normal saline (control group).

This study investigates electrical acupoint stimulation (EAS) administered in peri-operation for improving postoperative recovery in elder patients, who accept knee arthroplasty. the surgery cause to change of stress response, which might be associated with postoperative recovery of patient Totally, three groups are created, 1/3 participants receive transcutaneous electrical acupoint stimulation, 1/3 participants receive electroacupuncture, the rest 1/3 will use sham transcutaneous electrical acupoint stimulation.

Surgery has risk of morbidity and mortality. Risk factors include: patient factors; surgical factors; and anesthetic factors. The risk is much higher in emergency cases. The study of relevant risk factors can lead to improvement in patient management and reduction in mortality.
