Aim. To determine the need for pressure controlled non-invasive mechanical ventilation for reperfusion myocardial injury prevention in patients with ST-elevation myocardial infarction (STEMI). Methods. The study enrolled 61 patients admitted to the intensive care unit within 6 hours from the debut of chest pain, ST-segment elevation on electrocardiogram and oxygen saturation less than 90%. A percutaneous coronary intervention on an affected coronary artery was performed in all patients 30-90 minutes from admission. Non-invasive mechanical ventilation using the «MAQUET Servo-s» machine was started in patients of the first group (31 patients, mean age 66.3±10.7 years, males - 19, females - 12) with positive end expiratory pressure of 2-6 cm H2O, pressure support of 6-10 cm H2O, 40-60% O2 gas mix. Patients of the second group (comparison group, 30 patients, mean age 63.5±9.8 years, males - 16, females - 14) were offered a conventional treatment of ST-elevation myocardial infarction, including inhalations of humidified oxygen (6-8 liters per minute) using a nasal cannula. Results. Systolic, diastolic blood pressure and heart rate were 123.0±9.4 mm Hg, 81.2±11.3 mm Hg, 70.1±6.1 beats per minute in patients of the first group in 6 hours after admission. In patients of the comparison group the following parameters were measured as 157±12.4 mm Hg, 90.2±10.1 mm Hg, 92.6±10.2 beats per minute. The absolute risk increase of arrhythmias related to reperfusion myocardial injury was 17.8% (р 0.05) for the patients from the second group. Ejection fraction on a transthoracic echocardiogram (Teichholz method) was measured as 47.0±4.0 and 60.5±7.4% in patients from the first and the second groups respectively (р 0.05). Conclusion. Non-invasive mechanical ventilation decreases the risk for arrhythmias related to reperfusion myocardial injury, and increases the ejection fraction compared to conventional treatment and can be applied in patients with STEMI.
The aim of study is a comparative evaluation of the efficacy and safrty of ultra-low-dose spinal analgesia, epidural and paravertebral analgesia to labor pain relief. Material and methods. Four groups of 40 women tookpart in the study: one group is 40 patients, the labor pain was relieved by epidural analgesia. The second group consisted of 40 women in labor, anesthesia was carried out with ultra-low-dose spinal analgesia, 3rd group is 40 women who were anesthetized with paravertebral analgesia. The control group is 40 patients without anesthesia. The parameters of central hemodynamics were monitored: heart rate, blood pressure, mean arterial pressure. The motor block was estimated on the Bromag escale. The dynamics of the opening of the cervix, the duration of the first and second stages of labor was estimated. Implications and negative inluence of the anesthesia, the effect of analgesia on the fetus were also registered. Results. Epidural analgesia showed high efficiency and safety, but the frequency of hypotension in this group was significantly higher than in other groups, an inrease in the positivity of the exacerbation period was found. Ultra-low-dose spinal analgesia also had a sufficient analgesic effect in the first stage of labor. However, short-termeffect did not always provide effective analgesia of the second period of labor in comparison with other methods. In general the advantages of paravertebral analgesia in the form of a significant acceleration of cervical dilatation and a decrease in the time of delivery are revealrd. There were no cfses with score of 2 of Bromage scale of a motor block with paravertebral analgesia, while in the epidural group and the ultra-low-dose spinal analgesia isolated cases with a score of 1 and 2 were encountered. Paravertebral analgesia does not result to hypotensionas against other neuro-axial methods of analgesia. Conclusion. Neuroaxialmethods provide a sufficient level of analgesia can reduse anomalies of labor and do not affect negatively the fetus. All presented methods of analgesia have their place in obstetric anesthesiology. There is the possibility of choosing the most appropriate method of anesthesiain every obstetrical situation.
Aim. to identify the anesthesia method for carotid endarterectomy providing minimal ischemic neuronal damage and decreasing the number of post-surgical complications; to adjust the optimal treatment for associated neurological disorders. Methods. An assessment of anesthesia methods was performed in 190 patients who underwent the carotid endarterectomy. The intravenous anesthesia with propofol (first group, 60 patients), regional anesthesia using deep cervical plexus block (second group, 60 patients), and inhalational anesthesia with sevoflurane (third group, 70 patients) were compared. Brain perfusion parameters, neurological status, ischemic neuronal damage markers were examined. Results. In patients undergoing carotid endarterectomy an ischemic neuronal damage is provoked due to brain perfusion decrease as a result of common carotid artery clipping regardless of anesthesia method. Inhalational anesthesia was associated with relatively lower ischemic neuronal damage markers levels. Some patients form every group have developed serious post-surgical neurological complications (stroke, transient cerebral ischemic attack, neurological status deterioration). Post-surgical complications were registered in 10 (16.7%) patients from the first group, in 9 (15%) patients form the second group, in 3 (4.3%) patients from the third group. Citicoline was the most effective drug for associated neurological disorders treatment. Conclusion. Inhalational anesthesia with sevoflurane compared to intravenous anesthesia with propofol and regional anesthesia using deep cervical plexus block limits the neuronal damage and is associated with lower number of post-surgical neurological complications, which can be treated with citicoline.
