Comparison of the efficacy of 0.5% isobaric bupivacaine, 0.5% levobupivacaine, and 0.5% hyperbaric bupivacaine for spinal anesthesia in lower limb surgeries.

Various advantages of isobaric bupivacaine, levobupivacaine, and hyperbaric bupivacaine are described. There are no studies reliably determining the benefits of these forms of bupivacaine. The purpose of the study was to compare the efficacy of spinal anesthesia (SA) performed with 0.

COVID-19: positive experience with differentiated tactics of mechanical ventilation of the lungs for different phenotypes (L-phenotype).

Relevance: Studies have previously been published on a possible differential approach to respiratory therapy in patients with COVID-19 depending on the L- or H-phenotype.The authors believe that early tracheal intubation reduces the risk of lung injury. The use of deep sedation and low PEEP (6-8 cmHO) and early intubation may prevent transition to type H.

A comparison of the onset time of complete blockade of the sciatic nerve in the application of ropivacaine and its equal volumes mixture with lidocaine: a double-blind randomized study.

Background: The purpose of the current study is to create a new mixture of local anesthetics-one with a short time of block development and short action term (5 ml of 1% lidocaine solution) and another with a longer time of anesthesia development and a long analgetic effect (5 ml of 0.75% ropivacaine)-for use during surgical operations on extremities. The primary end point was the development of the complete sensory block of the sciatic nerve.
