[Optimization of the neuroautonomic inhibition and regulation of hemodynamics during subarachnoid anesthesia in abdominal delivery].

Pregnancy is considered in the spotlight of creation of general adaptation syndrome. It was revealed that 85% and 58% of healthy non-pregnant women had an inadequate autonomous nervous system (ANS) and circulatory system response respectively. This favoured the labour activity malfunction in 20% of women in childbirth when an abdominal delivery was needed. A traditional subarachnoid anesthesia (SA) in control group was accompanied by decrease of blood pressure (BP) to the numbers requiring a medicamentous correction (as by literature data). However, the central haemodynamics measures has shown a normal blood flow and the blood pressure correction was not performed. During surgery and in early post-operative period in all women in this group a parasympathetic tone has prevailed over, and the cardiac output was at the lower limit of the hypokinetic type of haemodynamics, which was accompanied with nausea and vomiting in 30% of women. Including the atropine administration into the traditional protocol of SA in cesarean section in pregnant patients with eu- and parasympathotonia (research group) has favoured the optimization of the neurovegetative inhibition of reflexes and stabilization of haemodynamics within the physiological ranges. Vagosympathetic block has been accompanied by sympathotonia with a lesser BP decrease compared to control group, absence of bradycardia, nausea and vomiting. Thus the BP can not serve as a criterion of the perfusion of essential organs, including uteroplacental haemodynamics, especially non-invasibe BP. Including the control of ANS tone dynamics, central haemodynamics and oxygen transport into monitoring guidelines in neuroaxial anaesthesia in abdominal delivery is necessary.

[Anaesthesia in abdominal delivery in pregnant patients with hypertension].

A differentiated administration of calcium antagonists in preoperative preparation of pregnant patients with hypertension enabled the conversion of circulatory system state to "normal pregnancy range": a conversion of hypokinetic (including the HES solution infusion) and hyperkinetic types of haemodynamics to eukinetic one, with the decrease of total peripheral resistance and myocardium need for oxygen, autonomous nervous system state to physiological sympathicotonia. Evidence shows that continued intra-operative treatment including tranexamic acid enables to maintain those results during the surgery. In postoperational period, the clinical manifestations of SIRS in patients who has received the mentioned therapy were marked less then in control group, and the newborns have a higher Apgar score.

[Anesthetic service and the postoperative period in pregnant women with gestosis].

The paper analyzes the results of using in the anesthetic maintenance of pregnant females with gestosis the algorithm of preventing possible impairments in the development of the general adaptation syndrome in response to pregnancy and surgical labor. Calcium antagonists (eliminating dysfunction of secondary calcium messenger), ketonal, and tranexamic acid (which inhibiting a number of pain and inflammation mediators), and hydroxyethyl starch-130/04 solution (regenerating the endothelium) were administered to prevent the clinical manifestations of the intraabdominal compartment syndrome, ischemia-pefusion, and the second wave of the systemic inflammatory response syndrome in response to surgery. The differential use of the above agents at all stages of anesthetic maintenance in pregnant women with gestosis promoted the postoperative preservation of the most efficient eukinetic hemodynamics and physiological sympathicotonia and the elimination of water metabolic disturbances more early than in the control puerperas. A more physiological postoperative course in the study group puerperas called for much less pharmacotherapy, which created more favorable conditions for postoperative maternal-neonatal contact (feeding, etc.).

[Emergency abdominal delivery and ventriculoperitoneal bypass in pregnant females with brain tumor].

The paper describes a case from the practice of the maternity hospital, City Hospital Sixty-Seven. The pregnant woman at gestational weeks 36-37 was found to have a brain tumor complicated by obstructive hydrocephalus and dislocation syndrome. Ventriculoperitoneal bypass and abdominal delivery were simultaneously performed under endotracheal anesthesia using propofol, nitrous oxide, and small-dose ketamine (25 mg), and after fetal extraction, fentanyl. At minutes 1 and 5, the Apgar score of the neonate was 8 and 8, respectively. The patient was discharged from the hospital in satisfactory condition on day 7 postoperatively and it was recommended that her surgical treatment at a neurosurgical clinic be decided.
