Complicated injury of the cervical spine is accompanied by a violation of blood circulation. This condition requires maintaining adequate perfusion pressure in order to prevent secondary damage to the spinal cord and multiple organ failure. The authors did not evaluate the effect of the urgency of spinal decompression on the severity and duration of systemic hypotension in this category of patients previously, as well as the presence of a connection between systemic hypotension and the outcome of the injury.

Objective. To determine the effect of early decompression of the spinal cord on the duration and characteristics of adrenomimetics use in the bundle of intensive care measures in the acute period of complicated injury to the cervical spine.

Material and Methods. A retrospective analysis of the treatment outcomes in 27 patients with complicated ASIA A cervical spine injury was conducted. Two groups were identified: Group I included 13 patients operated on within the first eight hours from the moment of injury; and Group II — 14 patients operated on within the period from eight to 72 hours. The analyzed parameters were: age, hemodynamic parameters, severity of organ dysfunction, duration of hemodynamic support, neurological status, time spent in intensive care unit, and length of hospital stay. Central hemodynamic parameters were registered using the impedance cardiography technique. To assess organ dysfunction, the SOFA score was used.

Results. Complicated injury of the cervical spine is accompanied by a decrease in systemic vascular resistance and cardiac index. Hemodynamic parameters and duration of hemodynamic support in groups were not statistically different. Statistically significant differences in the SOFA score between groups were obtained on the third and 10th day of the follow-up. Neurogenic shock was recorded in 70.4 % of cases. Positive dynamics of neurological deficit was observed only in two (15.4 %) patients of Group I.

Conclusion. The urgency of spinal decompression does not affect the duration of hemodynamic support, but reduces the severity of organ dysfunction and increases the risk of neurological disorder regression.

Aim of the study. To assess the accuracy of USCOM in patients after off-pump coronary artery bypass grafting (OPCAB).

Methods. We enrolled 14 patients who underwent elective OPCAB into an ongoing prospective observational study. The measurements of cardiac index (CI) based on USCOM (CIUSCOM) in comparison with thermodilution CI (CITD) were performed at seven stages during postoperative period. Statistical analysis included assessment of agreement in absolute values of CI using Bland–Altman analysis.

Results. Totally, 98 pairs of data were collected. According to Bland–Altman analysis of all pairs of data, mean bias between CIUSCOM and CITD was –1.09 L/min/m2 with limits of agreement of ±1.18 L/min/m2 and percentage error of 63 %. In a subgroup of stages with requirement of mechanical ventilation the intermethod bias was –1.16 L/min/m2 with limits of agreement of ±1.15 L/min/m2 and percentage error of 67 %, in a subgroup of stages after tracheal extubation the mean bias was –1.00 L/min/m2 with limits of agreement of ±1.23 L/min/m2 and percentage error of 59 %.

Conclusions. USCOM demonstrates poor accuracy with underestimation of CI compared to thermodilution technique both before and after tracheal extubation. This method can not be recommended as an acceptable alternative in cardiac surgery.
