Filter by: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
The investigators aimed to show the renal damage caused by increased intra-abdominal pressure in laparoscopic surgeries and to investigate whether its reflection on NIRS would be clinically effective.The main question it aims to answer are: Does pneumoperitoneum cause renal damage? NRS monitoring will be performed in patients undergoing laparoscopic surgery. Preoperative and postoperative blood tests will be performed at certain hours. N-GAL, urea and creatinine values will be recorded.
This study has been added as a sub study to the Simulation Training for Emergency Department Imaging 2 study (ClinicalTrials.gov ID NCT05427838). The Lunit INSIGHT CXR is a validation study that aims to assess the utility of an Artificial Intelligence-based (AI) chest X-ray (CXR) interpretation tool in assisting the diagnostic accuracy, speed, and confidence of a varied group of healthcare professionals. The study will be conducted using 500 retrospectively collected inpatient and emergency department CXRs from two United Kingdom (UK) hospital trusts. Two fellowship trained thoracic radiologists will independently review all studies to establish the ground truth reference standard. The Lunit INSIGHT CXR tool will be used to analyze each CXR, and its performance will be measured against the expert readers. The study will evaluate the utility of the algorithm in improving reader accuracy and confidence as measured by sensitivity, specificity, positive predictive value, and negative predictive value. The study will measure the performance of the algorithm against ten abnormal findings, including pulmonary nodules/mass, consolidation, pneumothorax, atelectasis, calcification, cardiomegaly, fibrosis, mediastinal widening, pleural effusion, and pneumoperitoneum. The study will involve readers from various clinical professional groups with and without the assistance of Lunit INSIGHT CXR. The study will provide evidence on the impact of AI algorithms in assisting healthcare professionals such as emergency medicine and general medicine physicians who regularly review images in their daily practice.
Commonly the pressure of about 14 mmHg is applied during laparoscopic liver resection (LLR) with moderate neuromuscular blockade. Lowering the pneumoperitoneum pressure combined with deep neuromuscular blockade may sustain optimal operating space with providing better short-term postoperative results. It has been proved in randomized controlled trials in colorectal or bariatric patients, however there is lack of similar data for laparoscopic liver resection. Doubts about lowering the pneumoperitoneum pressure too hasty are supported by apprehension of worse bleeding control during liver parenchyma transection and its impact on postoperative results. The aim of the trial is to assess the impact of standard (14 mmHg; arm 1) versus low (10 mmHg; arm 2) pneumoperitoneum pressure on intraoperative blood loss, what will be the primary outcome. As secondary endpoints following outcomes will be measured: quality of operating space, intraoperative adverse events, quality of recovery, postoperative renal function, 30-day postoperative complications rate, length of hospital stay. The investigators assume that lower pneumoperitoneum provides non-inferior blood loss control during laparoscopic liver resection with better postoperative results.
The investigators want to assess the effect of intraoperative low tidal volume vs intermediate tidal volume on respiratory mechanics, oxygenation and pulmonary complications in older patients undergoing Trendelenburg pneumoperitoneum surgery.
Previous studies conducted on the hemodynamic effects of pneumoperitoneum pressures created by different insufflation flows are very limited in the literature. In a current literature review, there was no study found comparing the effects of hemodynamic changes created by low and high insufflation flows and pneumoperitoneum pressure on cerebral oxygenation. The purpose of the study was to contribute to the literature by investigating the effects of pneumoperitoneum pressures created by different flows on brain oxygenation.
The present investigation is focused to assess the effects of positive end-expiratory pressure (PEEP) on respiratory system compliance in obese patients invasive mechanical ventilation for laparoscopic or robotic surgery with pneumoperitoneum
The investigators hypothesized that deep neuromuscular block compare to moderate neuromuscular block would reduce the rate of increasing intraabdominal pressure and operation can be completely done in lower pressure pneumoperitoneum and would improve laparoscopic space by measuring distance from the sacral promontory to the inserted trocar in patients undergoing laparoscopic gynaecological surgery.
18 participants (novices, intermediates and experts) performed in total 248 insertions in a systematic way on Thiel embalmed bodies with wide and small bore versions of the conventional VNc (conventional Veress Needle) and the VN+(The Veress Needle plus). Insertion depth was measured by recording the graduations on the needle under direct laparoscopic vision.
