Filter by:Patient undergoing laparoscopic radical prostatectomy in steep trendelenburg position are at risk to develop complication from brain edema. Ultrasound assessment of optical nerve sheath diameter is a simply, non-invasive method to estimate the increase of intracranial pressure. It is unknown how optical nerve sheath diameter changes after prolonged head down position.
Pneumoperitoneum created during laparoscopic surgeries has some effects on human physiology. Increased intraabdominal pressure results in increased intrathoracic pressure, and eventually may result in increased intracranial and intraocular pressures. In this study we aimed to identify intraocular and intracranial pressure changes during the perioperative period due to the pneumoperitoneum created for laparoscopic cholecystectomy surgeries. Intraocular pressure will be measured directly from the eye. Intracranial pressure will be estimated by measuring optic nerve sheath diameter changes ultrasonographically.
Peritoneal perfusion during laparoscopic surgery is quantified by video recording after intravenous injection of indocyanine green at a pneumoperitoneum pressure of 8, 12 and 16 mmHg.
The purpose of this study is to evaluate whether the change of stroke volume index(△SVI) induced by the rapid mini-fluid administration can predict fluid responsiveness in patients with pneumoperitoneum
The present study is designed to investigate the short-term and long-term renoprotective role of pneumoperitoneum preconditioning in patients undergoing laparoscopic partial nephrectomy.
The primary purpose of this study is to investigate the effect of pneumoperitoneum on remifentanil requirements in the surgical pleth index-guided analgesia for laparoscopic gastrectomy.
This study evaluates the ability of ultrasound to identify intraperitoneal free air. The study will consist of blinded review of abdominal ultrasound images of patients before and after laparoscopic surgery, a procedure which results in the introduction of air into the peritoneal cavity.
The investigators plan to compare insufflation pressures during robotic assisted laparoscopic prostatectomy (RALP). Standard pressure is typically 15 mmHg, while in a previous study the investigators determined that 6 mmHg is possible routinely. Therefore, the investigators plan to compare the clinical outcomes of participants at a pneumoperitoneal pressure of 15 versus 6 mmHg.
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.
During laparoscopic surgery, the abdomen is inflated with carbon dioxide for abdominal imaging and increased intraabdominal pressure affects intraabdominal structures and abdominal wall.
