Comparative Study[Evaluation of the effect of different anesthesia techniques on the immune status of pregnant women].
Cellular immunity has been studied in women after surgical delivery. Initial immune deficiency has been found in all the patients. ⋯ Minimum effect of spinal anesthesia on the immune status, as compared to general anesthesia, has been established. The use of spinal anesthesia is recommended during cesarean section in patients with immune deficiencies.

[General anesthesia in patients with abdominal trauma in a district hospital].
The paper reviews three techniques of anesthesia used in 113 patients with abdominal trauma and thoracoabdominal wounds. In 42 patients N2O-ether (halothane)-O2 anesthesia was used. In 40 patients thalamonal-hydroxybutyric analgesia was used. ⋯ In six patients trauma was incompatible with life. From the point of view of their effect on the cardiovascular system two techniques of anesthesia seem to be most advisable: thalamonal-hydroxybutyric general anesthesia and general anesthesia with ketamine. Postoperative lethality was 6 patients (5.6%).

We present the results of intraoperative monitoring of motor evoked potentials from 34 patients undergoing spinal surgery under total anesthesia with intravenously administered propofol. Intraoperative recording was performed with transcranial electrical stimulation. Two groups of patients were studied: 1) a control population of 26 patients undergoing lumbar discectomy for prolapsed intervertebral disc, all of whom had normal preoperative motor conduction; and 2) a population of 8 patients undergoing neurosurgical procedures for spinal tumor (5 patients) and spinal arteriovenous malformation (3 patients), all of whom had abnormal preoperative neurological signs and abnormal preoperative motor conduction. ⋯ Intraoperative monitoring was successful in 87% of the patients in the pathological group. We observed significant changes in both amplitude (greater than 50%) and/or onset latency (greater than 3 ms) from the intraoperative baseline that indicated either improvement (3 patients) or deterioration (2 patients) in motor conduction within minutes of surgical maneuvers anticipated to alter spinal cord function. Only permanent complete loss of intraoperative motor conduction (1 patient) correlated with a significant change in the postoperative neurological state.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative course after sufentanil or fentanyl anesthesia for coronary artery surgery.
Postoperative hemodynamic effects were compared in 50 patients randomly selected to receive either sufentanil, 25 micrograms/kg, or fentanyl, 100 micrograms/kg, anesthesia for coronary artery bypass grafting. The two groups exhibited similar patient demographics; dose of premedicants and muscle relaxants; and use of inhalation agents. Values for 15 hemodynamic variables were recorded at baseline and at six postoperative times. ⋯ Elimination half-lives differed significantly: 554 +/- 91 minutes (fentanyl) versus 277 +/- 60 minutes (sufentanil). Serum concentrations of both decreased linearly. The added advantages of postoperative hemodynamic stability could be important in the choice of anesthetic.

Randomized Controlled Trial Comparative Study Clinical Trial
Combined epidural and general anesthesia versus general anesthesia for abdominal aortic surgery.
The goal of this randomized study of high-risk surgical patients was to determine whether intraoperative thoracic epidural anesthesia in combination with light general anesthesia alters postoperative morbidity when compared to a standard technique of "balanced" general anesthesia. A total of 173 patients scheduled for abdominal aortic reconstruction were admitted to the study; 86 were to receive "balanced" general anesthesia (group 1) and 87 thoracic epidural anesthesia in combination with light general anesthesia (group 2). Preoperative evaluation included standard clinical tools, dipyridamole thallium gammatomography, and radionuclide angiography. ⋯ In group 2, 6 patients with a nonfunctioning epidural catheter due to technical failure received a balanced general anesthesia and were eliminated from the study. During the postoperative period, group 2 received analgesia of subcutaneous morphine (n = 26), epidural fentanyl (n = 25), or epidural bupivacaine (n = 30). Cardiovascular morbidity did not differ between the two groups: 22 patients in group 1 and 19 patients in group 2 had a major postoperative cardiac event.(ABSTRACT TRUNCATED AT 250 WORDS)
