Filter by:This study aims to address the existing gap in knowledge by conducting a comprehensive comparison of the incidence of pain and common bile duct injuries in patients undergoing laparoscopic cholecystectomy using Low pressure pneumoperitoneum versus high pressure pneumoperitoneum.
Bariatric Surgery for morbid obesity is indicated when BMI > 40 kg/m2 without comorbidities or BMI > 35 kg/m2 with co-morbidities. Different surgeries performed for obesity are classified as restrictive, malabsorptive, and hybrid procedures. Because laparoscopic surgery has increased the interest and growth of bariatric surgery, soaring demand for laparoscopic bariatric surgery from patients has boosted the boom in bariatric surgery worldwide. Achieving pneumoperitoneum is the initial and one of the most crucial steps in any laparoscopic surgery, giving the surgeon working space to operate on a particular organ/organ system. Usually, pneumoperitoneum is achieved either by a closed technique with a veress needle or an open technique with many variations like finger assisted or the conventional open technique. Given the excess amount of subcutaneous fat in morbidly obese patients, putting a veress needle to achieve pneumoperitoneum successfully is particularly challenging which takes a toll on the operating surgeon when he/she is trying to locate the midline one can either overshoot to cause omental emphysema or undershoot getting lost in the subcutaneous fat. It is usually done in the supra umbilical area. Sometimes, due to previous surgical scars other sites are preferred. Sonography is routinely used by radiologists with negligible radiation exposure. Anesthesiologists in the operating room have used it for many assisted procedures like central line insertion / giving nerve blocks. It can also be used in obese patients undergoing metabolic surgery to assist in creating pneumoperitoneum by a veress needle. Advantages of Intraoperative ultrasonography in this particular study : 1. To quantify the thickness of subcutaneous fat 2. To visualise the linea alba and guide the veress needle safely into the peritoneal cavity 3. Real-time visualisation of the pneumoperitoneum created 4. Avoid complications like omental emphysema, bowel or vascular injury
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 patients during robotic surgery in the pelvis, often 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. In this study the circulatory effects in patients with normal heart function and preexisting heart failure will be studied during robotic surgery in extreme Trendelenburg positioning 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. This study can identify patients at risk of developing critical circulatory failure during this type of surgery.
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.
