The hydrodynamics of hyperbaric solution streams through spinal needles of types and sizes by different administration routes was experimentally studied. Administration rates of not more than 1,0 ml/min were found to be allowed to ensure a laminar stream model. The rates of 1,0-3,0 ml/min led to the appearance of hydrodynamic instability-associated turbulence. The rate of over 3,0 ml/min gave rise to turbulence associated with the thickened jet interface. The hydrodynamic shock of fluid flow with an obstacle as a model wall is a reason for the turbulent spread of a hyperbaric solution on the glass spine model. This mechanism of turbulence does not depend on the type of a spinal needle. The size of spinal needles affected the volume of distribution. Infusion through thin needles at equal rates increased the strength of shock with the model wall and the area of spread of a dyed hyperbaric solution. The advantage of needles with a side hole to achieve unilateral hyperbaric solution spread was found at rates of 1,5-3,0 ml/min.

The study was conducted to assess adequacy of postoperative analgesia in surgical patients of Krasnoyarsk regional clinical hospital. The study included patients undergone elective surgery. The pain intensity was assessed using 10-bals visual-analog scale (VAS). The quality of sleeping during the first night following the operation as well as subjective feeling connected with postoperative pain were registered and evaluated. It was noted that using of regional anesthesia methods prolonged painless period and decreased number of complaints during first 24 hours after surgery.

Use of neuraxial block in a patient with severe kyphoscoliosis is controversial. It is believed that severe kyphoscoliosis is a contraindication to neuraxial anesthesia. In this article, we describe two cases of successful epidural anesthesia in pregnant women with severe kyphoscoliosis. We suggest that a pregnant with severe kyphoscoliosis may be successfully managed by epidural anaesthesia for caesarean section.

The project of clinical guidelines proposed by Federation of anesthesiologists of Russia is dedicated to questions of perioperative management of patients suffering from neuromuscular diseases and other pathological conditions and disorders that involved interaction between neural and striated muscular systems.
