Filter by:During laparoscopic surgery, the abdomen is inflated with carbon dioxide for abdominal imaging and increased intraabdominal pressure affects intraabdominal structures and abdominal wall.
This research aims to study the composition of the peritoneal exhaust gas during laparoscopic surgery to detect and possibly quantify the presence of air and / or N2O. This purely descriptive work is part of other experimental work that the investigators have already published.
The purposes of this study is to investigate the effects of moderate vs. deep neuromuscular block on respiratory mechanics and biotrauma in patients with intraoperative protective lung ventilation for laparoscopy.
Substudy of the RECOVER trial (a randomised controlled trial comparing the effect of low pressure pneumoperitoneum with deep neuromuscular block versus normal pressure pneumoperitoneum with moderate neuromuscular block during laparoscopic colorectal surgery on early quality of recovery) investigating innate immune homeostasis after laparoscopic colorectal surgery.
The primary purpose of this study is to investigate the effect of pneumoperitoneum on the continuous and non-invasive hemoglobin monitoring during laparoscopic gastrectomy
Postoperative cognitive decline (POCD) is a common and impactful outcome of surgical procedures in older adults. The pathophysiology and causative mechanisms for POCD are poorly understood. The robot-assisted radical cystectomy (RARC) is increasingly utilized. In patients undergoing RARC, Although prolonged Trendelenburg position and pneumoperitoneum can increase the cerebral blood flow, the excessive cerebral perfusion can lead to encephalemia, which reduce the oxygen uptake of brain tissue and cause insufficient oxygenation of brain tissue at the cellular level. POCD may take place due to cerebral hemodynamic changes. The goal of the current study is to investigate the combined effect of this position and CO2 pneumoperitoneum on POCD during RARC with the monitor of cerebral oxygen.
This study aimed to evaluate the increase of intraabdominal pressure 12- 14 mmHg caused by pneumoperitoneum resulted from carbon dioxide (CO2) insufflation induce glycocalyx endothelial injury that cause kidney tubular injury on live donor patient that undergo laparoscopic nephrectomy surgery, and decreasing the intraabdominal pressure to 8-10 mmHg during surgery is expected to reduce the injury.
The purpose of this study is to compare the 1: 1 I: E ratio VCV and the autoflow VCV in patients undergoing robot assisted laparoscopic prostatectomy
This is a prospective study whereby it involves patients who are planned for bariatric surgery. In the bariatric surgery procedure, pneumoperitoneum pressure will be the experimental aspect in this study. The pneumoperitoneum pressure will be adjusted to either 8-10 mmHg of low pressure or to 12-15mmHg of standard pressure.
Laparoscopic surgery is now widely established.Laparoscopic surgery involves insufflation of a gas (usually carbon dioxide) into the peritoneal cavity producing a pneumoperitoneum. The raised intra-abdominal pressure of the pneumoperitoneum, alteration in the patient's position and effects of carbon dioxide absorption cause changes in physiology, especially within the cardiovascular and respiratory systems.
