Obesity is associated with a number of anaesthesia-relevant risks. Regional anaesthesia procedures offer a number of advantages, but they also pose an anaesthetic challenge. For example, the identification of superficial landmarks according to the degree of obesity is difficult to impossible, which reduces the success rate compared to normal weight patients. The use of ultrasound (US) technology with the ability to visualize the target structures may be helpful in performing neuraxial and peripheral blockades. However, a lot of experience and training is required because the ultrasound imaging of very low-lying nerves in obese patients is limited due to the physical limitations of US technology.

To identify the value of using the ultrasound in applying a commonly used regional anaesthetic procedure (spinal anaesthesia) when compared with the conventional landmark guided approach, ...
The aim of this study is to compare conventional and ultrasound guided paravertebral blocks to with respect to efficacy, patient satisfaction and complication rates.
Regional anaesthesia is a frequently used procedure. Currently, blockades are increasingly carried out without nerve stimulation. The risk of nerve lesion is about 3 %. Industrial efforts ...

A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as diabetes, hypertension and METABOLIC SYNDROME X.
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
