[The choice of anesthesia during abdominal delivery in patients with severe forms of late pregnancy toxemias].

Sixty eight anesthesia procedures during abdominal delivery in patients with late toxemia of pregnancy have been analysed. In 32 cases the diagnosis was preeclampsia, in 8 cases--eclampsia, in 28 cases III degree nephropathy. Depending on the variant and method of anesthesia the subjects were divided into 3 clinical groups. Group I comprised 31 women to whom cesarean section was performed under general endotracheal anesthesia. In group II (24 pregnant women) analgesia was achieved by prolonged epidural anesthesia (PEA). In group III (13 patients) a combination of PEA and superficial endotracheal anesthesia was used. Analysis of the anesthesia techniques in patients with severe late toxemia of pregnancy has established that in endotracheal anesthesia it is sometimes impossible to block completely pathological and operation-induced nociceptive pulsation. PEA has a good analgetic effect but ensures no neuroautonomous protection, and upon discontinuation of action of the local anesthetic there is a danger of the onset of the convulsion syndrome and signs of preeclampsia or eclampsia. Taking into account the advantages and disadvantages of endotracheal anesthesia and PEA, a technique based on the combination of both variants has been selected, which ensures optimal anesthesiological protection in abdominal delivery.
