Filter by:A randomized clinical trial aiming to compare two different techniques of performing a nerve blockage of the abdominal wall. When performing surgery on the colon and rectum surgeons often use a minimal invasive technique called Laparoscopic surgery. In this technique small incisions in the abdominal wall are used to put special ports trough into the abdomen so that surgical instrument can be inserted. To minimize the pain caused by these port-holes, a so-called Transversus Abdominus Plane (TAP) nerve block is performed directly after the surgery before the patient wakes up from narcosis. This procedure is normally performed by the anesthesiologist using ultrasound to guide a needle to the right depth or "plane" in the abdominal wall where the nerves are gathered. When in the right position a local anesthetic is injected that will block the nerves and thereby anaesthetizing the abdominal wall for the first post-operative day. Recently an alternative way of guiding the needle to the right position has been presented. By using a laparoscopic camera the surgeon can easily guide the needle and inject the local anesthetics during surgery. This way of performing the TAP block may save valuable time compared to the more cumbersome ultrasound guided technique while also not needing an extra anesthesiologist in the operating theater. In this study we aim to include participants selected for elective minimal invasive surgery of the colon or rectum, where a TAP block is normally performed. The participant will be randomized to either a TAP block performed by the surgeon using laparoscopic guidance or by an anesthesiologist using ultrasound guidance. The intended surgery in itself will not be altered. During surgery we will measure TAP procedure time, total surgical time, total duration of anesthesia and total time spent in the operating theater. The following 2 postoperative days we will measure experienced pain using a validated pain-score (VAS) and measure the total consumption of pain medication. 2 days after surgery the study ends for the participant and there is no further follow up. By conducting this study we can determine whether a laparoscopic guided TAP by the surgeon, compared to a traditional ultrasound guided by the anesthesiologist; gives a shorter procedure time, shorter time of narcosis and reduced consumption of pain medications post-operative while still not affecting the experienced pain by the participant.
In this single center, double-blind, randomized controlled clinical trial, we will include 648 diabetes patients aged 18-70 undergoing laparoscopic pelvic tumor resection. They will be randomized to the following four groups: high-pressure pneumoperitoneum (10mmHg)+ deep neuromuscular block group, high-pressure pneumoperitoneum (15mmHg)+moderate neuromuscular block group, low-pressure pneumoperitoneum + deep neuromuscular block group and low-pressure pneumoperitoneum+moderate neuromuscular block group. Deep neuromuscular block is defined as post tetanic count (PTC) 1-2, and low neuromuscular block is defined as train-of-four (TOF) twitch 1-2. The outcomes will be indicators for acute kidney injury and surgical condition.
Study to assess the safety, and performance of the LapBox in patients in terms of duration of deployment, organ insertion into the "LapBox" bag, ease of use, success of containment and performance.
Previous surgery and obesity has disputed as an unfavorable factor during Total Laparoscopic Hysterectomy. The aim of the investigator's study was to assess the effects of previous abdominal surgery and obesity on intra-operative and post-operative outcomes of TLH.
To record the digital data from monitoring instruments (standard patient monitor) containing cardiovascular system information, and from depth-of-anesthesia monitoring modules (Bispectral index, Entropy module, Surgical Plethysmography Index, Analgesia Nociception Index) containing neurological system information captured in the patient monitor, as well as the physiological data regarding anesthetic dosage, respiratory gas analysis and the standard monitoring requirement of anesthesia. The investigators also record the precise time points of detail surgical steps during the laparoscopic cholecystectomy. Clinical data collected from these monitoring instrument will be used to gain more understanding of the complex interaction between anesthetic effect, surgical procedure, autonomic response and drug modeling. The goal is to obtain the performance of each monitoring index in detail surgical steps.
