Filter by:Pain still remains a limiting factor in early discharge of patients undergoing laparoscopic cholecystectomy. Almost all earlier studies done to compare the efficacy of local anaesthetics used intraperitoneally as compared to intraincisionally used equal amounts of drugs at the two locations, usually 10-20 ml. Using this large amount of drug in the small space of intraincisional location as compared to similar amount of drug in large intraperitoneal space created an inadvertent bias in favor of patients receiving the drug intraincisionally so such patients naturally experienced less pain. The investigators decided to standardize the drug used at these two locations as 1ml/cm and conduct a new study comparing the effects of drugs in relieving pain when used at these two locations.
The purpose of this study is to determine weather using warmed (body temperature) 0.75% Ropivicaine to convert labour epidural analgesia to surgical anaesthesia, reduces the onset time of surgical block, compared to standard room temperature
The patients will be included the 1. or 2. day after surgery. All THA patients will be screened. Those reporting VAS > 40 during active 30 degrees hip flexion will be asked to participate. Included patients will receive 2xNCFL (singleshot) first placebo (8 ml saline) and then ropivacaine (8 ml ropivacaine 7,5mg/ml) or the other way around (randomized). There will be 45 minutes between the two blockades. The blockades will be ultrasound guided.
It is established that the local anesthetic that is administered during an interscalene block affects the autonomic outflow to the heart. This is very well seen during shoulder surgery when the patient is positioned in beach chair pasition. The investigators want to study the different effect of the two concentrations (0.5% and 0.375%) of ropivacaine on the autonomic nervous system through blood pressure and heart rate measurements.
