SFIB vs PENG Block in the Anesthesia for Total Hip Replacement

Plain-language summary

Total hip replacement is one of the most common orthopedic operations. According to statistical studies, more than 1 million of such surgical interventions are performed annually in the world. The average age of primary hip replacement surgery is 69 y.o. Modern approaches of control of general anesthesia allow safe performance of different surgical interventions under general anesthesia. However, general anesthesia does not have an effective and long-lasting effect on relieving operational stress compared to neuraxial anesthesia. To achieve a similar effect, it is necessary to adhere to the principle of multimodality of anesthesia, and the most promising method is a combination of general and regional anesthesia. peripheral blocks are described in the literature, aimed at analgesia directly in the hip joint area, and effectively used in orthopedics. Most blocks are currently performed under ultrasound control, the risk of nerve damage and accidental intravascular administration of local anesthetics is potentially reduced. It was established that the use of ultrasound guidance reduces the number of attempts and the amount of anesthetic administered, as well as reduces the time required to perform a block. Another predicted effect is a reduction in the doses of opioids and non-steroidal anti-inflammatory drugs (NSAIDs), which can cause gastrointestinal bleeding and have a nephrotoxic effect, and can also depress breathing. It should be noted that patients over 65 y.o., have the highest risks of these side effects. This study aims to compare the effectiveness and safety of SFIB and PENG block in hip replacement, as well as evaluation of the effectiveness of combined anesthesia in comparison with general anesthesia without the use of peripheral blocks.
