Filter by: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.
This study is an observational study measuring the esophageal pressure in anesthetized surgical patient undergoing changes in posture and pneumoperitoneum
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.
Laparoscopic surgery (surgery with the use of a camera and small instruments) uses insufflation, which is the standard medical practice where CO2 (carbon dioxide) gas is blown into the abdomen to create space for surgical procedures. The purpose of this study is to investigate whether heating and humidifying surgical CO2 will reduce surgery-related inflammation and postoperative pain.
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
The proposed study aims to assess the effect of different levels of muscle relaxation on the success of low-pressure insufflation, surgical conditions and patient recovery following laparoscopic repair of a ventral hernia (VHR) between 2 and 10cm in diameter. Patients will be randomized to moderate (TOF 1-2) or deep (post tetanic count 1-2) relaxation. Specific Aim 1. Compare two different modes of neuromuscular blockade (moderate and deep) on the ability to maintain low insufflation pressure during laparoscopic VHR. All procedures will start with low-pressure insufflation (8 mm Hg). Surgeon assessment of the conditions will be serially performed during surgery on an established visual scale. If conditions are deemed less than adequate (score 1-2), insufflation pressure will incrementally increase up to 15 mm Hg. Outcome for this specific aim will be the mean insufflation pressure during each procedure, and the ability to perform low-pressure laparoscopic VHR. Specific Aim 2. Evaluate the success of moderate neuromuscular blockade on the ability to maintain good conditions (visual scale grade 4 or 5) for each. Surgical conditions will be considered successful when scores are maintained at 4 or 5 throughout the duration of the procedure. Outcome for this aim will be the mean score for surgical condition assessment for each procedure, using a previously published surgeon-driven scoring system (score 4-5 will be used as a surrogate of good visualization). Specific Aim 3. Assess patient recovery with low and high insufflation pressures during laparoscopic VHR. Patient overall satisfaction with recovery, pain level, pain medication requirement, PONV incidence and severity will be assessed in multiple time points following surgery. Outcomes for this aim will be mean pain (visual scale), PONV severity (analogue score) and incidence (binary outcome), and patient satisfaction using the QoR-15 survey. Assessments will be performed at 30 minutes, 1, 12 and 24 hours following surgery.
