Filter by:The purpose of this study is to assess the safety and ease of use of a trocar placement access device (TPAD) to assist with obtaining peritoneal access with a Veress needle, and for placing a primary trocar, during laparoscopic surgery.
BACKGROUND: The steep Trendelenburg position and pneumoperitoneum are used to improve surgical visibility in robot-assisted laparoscopic radical prostatectomy (RALRP). However, these procedures can lead to hemodynamic changes. This study aimed to investigate the effects of these interventions on the perfusion index (PI) and the Pleth variability index (PVI) in patients undergoing RALRP under general anesthesia. METHODS: Fifty-three patients scheduled for RALRP underwent standard monitoring; PI and PVI values were monitored using a finger probe. PI, PVI, hemodynamic and respiratory parameters, and intraabdominal pressure were recorded before and after anesthesia induction, after adopting the Trendelenburg position, after pneumoperitoneum, after pneumoperitoneum and the Trendelenburg position, at 15 min, 30 min, in the supine position, after carbon dioxide (CO2) desufflation, and after extubation.
This study aims to investigate the effect of varying insufflation pressures on post-operative pain and adequacy of surgical field visualization among patients undergoing laparoscopic surgery with a minimally invasive gynecologic surgeon.
The field of robotic-assisted laparoscopic surgery increases all the time. Older and more fragile patients which are not suitable for major open surgery could be scheduled for robotic- assisted surgery. The peroperative anesthesiological challenges and stresses during this type of surgery could anyway be even more prominent. The extreme positioning of these patients during surgery, for example 30 degrees head down tilting (Trendelenburg positioning), should increase the work load of the heart significantly. There are no studies concerning fragile patients with heart failure during these conditions. We will study patients during extreme positioning during robotic surgery and compare the effects between patients with normal heart function and preexisting heart failure. During surgery the work load and performance of the heart will be monitored using an esophageal doppler and optical spectrophotometry measuring regional saturation of the brain.
The turbine-based insufflator for minimal access surgery provides a new technological basis for minimal invasive surgery insufflation. Turbine technology permits highly accurate pressure control, an intra-abdominal volume that is dynamically adapted to ventilation, and oscillometric measurements of abdominal compliance. This first-in-human study aims to evaluate technologic feasibility in terms of pressure stability performance and the safety of the device.
The aim of this study is to evaluate the effect of deep neuromuscular block on postoperative pain, duration of surgery, quality of surgical field, length of recovery room stays, Total amount of rescue analgesic, postoperative nausea/vomiting, and length of hospital stay.
Upon introducing pneumoperitoneum our research team noticed a reduction in expiration time displayed on the screen of the anesthesia machine. Since most respirators do not directly indicate the length of expiratory time and the average expiratory flow rate, we decided to investigate whether pneumoperitoneum really accelerates expiratory flow rate and thus shortens expiratory time.
Laparoscopic bariatric surgery are becoming the most used procedure to treat the obesity. To facilitate safe initial access to the abdominal cavity, we insert an optical viewing trocar at the left hypocondrium. The aim of this study is to systematically evaluate all published data existing in the literature to analyze the safety of optical trocars in patients undergoing bariatric surgery and to compare these data with our experiences.
The objective of this prospective, international cohort is to incorporate the low stable pressure (using Airseal Insufflator) approach and its associated parameters into the early rehabilitation program after colorectal surgery so as to shorten hospitalization up to the ambulatory care and reduce postoperative pain and opioid consumption.
Laparoscopic nephrectomies are commonly performed these days and are considered gold standard for both benign and malignant diseases as well as for donor nephrectomies. Despite being a widely performed surgery worldwide still there are areas of uncertainties due to lack of evidences. One of such area of dilemma is the optimum pressure of pneumoperitoneum. This study aims to identify if lower pressure of pneumoperitoneum is safe during laparoscopic nephrectomies. This is a hospital based prospective randomized control study. All the patients undergoing laparoscopic nephrectomies at department of urology and kidney transplant surgery will be eligible for study. Patients will be divided into low pressure or standard pressure pneumoperitoneum by simple random sampling and comparison of various intraoperative and post-operative parameters will be done to assess the safety of low pressure pneumoperitoneum
