Filter by:The effect of surgery, in contrary to critical illness, on muscle weakness hasn't been thoroughly investigated. Recent data suggest that elective surgery may also induce muscle weakness. The neuro-endocrine stress response could be involved in the pathophysiology. Whether the mode of anesthesia/analgesia can influence muscle weakness, by influencing the neuro-endocrine stress response is unknown. Gaining insight in this matter could affect quality of care and benefit patient recovery and satisfaction.
Local intra-articular injection of anesthetics (LIA) is increasingly used during knee arthroscopy for pain relief. The LIA can only be performed at the end of surgery as the knee joint is continuously flushed during the arthroscopy. As a consequence, an optimal analgesic effect is only obtained one hour after surgery and opiates are typically used as pain relief in the immediate postoperative period. Since these opiates have a number of side effects such as nausea, vomiting and drowsiness, other analgetic methods are desirable. Intravenous administration of lidocaine, a safe, inexpensive analgesic, is already used in major (abdominal) surgeries and might also be a promising method for pain relief in the first hour after knee arthroscopy, in anticipation of the onset of the analgesic effect of the LIA. The aim of this study is to verify if systemic administration of lidocaine has a beneficial effect on the pain immediately after knee arthroscopy. In addition, the effect of systemic lidocaine administration on postoperative nausea, vomiting and general patient comfort will be evaluated.
Bowel cancer is the second most common cause of cancer-related death in the UK, with 50,000 new cases and over 15,000 deaths annually. Surgery is the mainstay of treatment and the most common complications are an infection of the wound or lungs. These can lengthen hospital stay, reduce the quality of life, and even increase the risk of death. Bowel cancer patients are often malnourished. Optimising nutrition with supplements such as fish-oils can improve the immune response of patients, helping prevent such complications, shorten hospital stay, improve quality of life and overall survival.
Currently there is a nationwide epidemic in opioid abuse and overdose deaths. While the opioid epidemic is multi-factorial one major source of excess opioids may be over-prescribing in the post-operative period. There is wide variation in the prescribing practices for post-operative pain control and there is no standard of care for pain control after minor laparoscopic surgery in general or after gynecologic laparoscopy. There is also evidence to show that on average half of the opioids prescribed are unused by the patient. The aim of the study is to evaluate two opioid prescription regimens.
Acute severe ulcerative colitis [ASUC] patients have high risk of no response to medical treatments and might miss the best timing for surgery when waiting for the medical response. Thus, we investigated whether biomarkers which could early predict the surgery risk of patients with ASUC on admission.
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.
The investigators want to verify whether the surgical outcome of vessel-sparing anastomotic repair in isolated short bulbar urethral strictures is not inferior to the surgical outcome of transecting anastomotic repair. Furthermore, the investigators compare the functional outcome of both techniques verifying if there is less erectile dysfunction after vessel-sparing anastomotic repair than after transecting anastomotic repair.
This study evaluates the influence of two different end-inspiratory pause (EIP) times on respiratory mechanics and arterial gases of surgical patients when ventilated under an open lung approach (OLA) strategy. The investigators evaluate the impact of using EIP 10% versus 30% of the inspiratory time on a volume control model. The investigators also analyse the potential influence of these EIP on pulmonary gas distribution measured by electric impedance tomography.
The purpose of this study is to evaluate the postoperative pain and discomfort using flurbiprofen axetil or nalbuphine administration after orbital decompression under general anesthesia.
Evaluate difference in postoperative opiate consumption when patients do or do not receive a quadratus lumborum block preoperatively for hip arthroscopy.
