Filter by:Aim The general aim of this study is to improve post-operative pain and reduce morphine consumption following laparoscopic ventral hernia repair (LVHR). We specifically aim to conduct a randomized, double blinded, controlled trial to investigate the effect of intra-peritoneal local anaesthesia infusions on post-operative morphine consumption and. Methods: Patients will be randomised by computer generated random numbers (random permutation) and opaque envelope methods. At closure, one small 2mm catheter belonging to the AutoFuser pain pump system will be placed in the peritoneal cavity between the onlay mesh and parietal peritoneum. In the treatment arm patients will receive 275mL of 0.2% ropivacaine at 4mL/h. In the placebo arm, 275mL of 0.9% normal saline will be used in a similar fashion. The infusions will run for 68 hours total. All members involved in patient care (with the exception of one independant research fellow) will be blinded to the above. After 68 hours the pump will be stopped and the catheter will be removed. Assessment of post-operative pain will be performed by visual analogue scale, and total opiate consumption will be collected and converted into morphine equivalents. Health significance: Local anaesthesia has become an important addition to multimodal regimens of analgesia following surgery. Recent studies have shown that local anaesthetic (LA) wound infiltration has improved post-operative pain when compared with standard opioid regimens for pain relief. Only one previous study looked at bupivacaine infusions into the hernia sac for three days following LVHR. This study found no improvement in post-operative pain or morphine consumption. We aim to demonstrate improved pain and reduced morphine consumption using an alternative catheter insertion technique and ropivacaine as the desired LA agent.
The study investigates the impact of the introduction of a surgical checklist on the incidence of complications and mortality within 30 days after surgery in patients scheduled for elective non-cardiac surgery. Patients scheduled for elective surgical procedures lasting longer than 20 minutes at are eligible. Surgery is performed in a single tertiary care center. Study design is an open trial before and after intervention (implementation of the checklist "safe surgery saves lifes").
It is well known that femoral neck fractures carry a significant increase in patients' mortality and that surgical intervention is the preferred treatment. Any delay in operating on such patients would inevitably increase their risk of developing complications. One of the reasons for such unintentional delay would be the hypercoagulative status of patients taking warfarin. The CHEST 2008 guidelines suggest reversing warfarin with Vitamin K for patients who need urgent operation. The aim of this study is to compare different roots and doses of Vitamin K.
