[Effect of potentiated anesthesia on clinical indices in boars]. / Vliianie na potentsiranata anesteziia vurkhu niakoi klinichni pokazateli pri nerezi.

Successful i/v potentiated anesthesia was carried out (injecting the agents in the ocular venous sinus) without surgical intervention with 6 boars and in castration of 14 others. Premedication consisted in the application of 50 gamma per kg body mass, subcutaneously, and a mixture of droperidol (0.25 mg/kg) and phentanil (0.05 mg/kg), intravenously. Fifteen min later a 5 per cent solution of thiopental sodium was introduced i/v as follows: with animals of up to 50 kg--at the rate of 13 mg/kg body mass; with those of 50 to 100 kg--at 10 mg/kg; and with boars of over 100 kg--at 5 mg/kg. Anesthesia lasted 30 min and as long as 30 min after narcosis was over. During anesthesia full relaxation of muscles set in, and the unconditional and ocular reflexes were totally suppressed. The colour of the tongue, and the wetness of mucous membranes remained unchanged. Full lack of response to pains set in. The pulse remained consistent, strong, and rhythmic. Neither were there hythermia and any laryngo- and bronchial spasms. In castration during the general anesthesia the animals showed no response to pains over the entire period of operation. Such potentiated anesthesia made possible and totally convenient all minor surgical interventions in swine.

[Hematologic and biochemical changes in the blood of boars undergoing potentiated anesthesia with droperidol, fentanyl and thiopental]. / Khematologichni i biokhimichni promeni v kruvta na nerezi pri potentsirana anesteziia s droperidol, fentanil i tiopental.

Intravenous potentiated anesthesia was made with six clinically normal boars of the White Bulgarian breed, weighing 50 kg, premedication of Atropini sulfas (50 gamma/kg M., s/c) and of a mixture of Droperidol (0.25 mg/kg M.) and Fentanyl (0.05 mg/kg M.) introduced via Sinus venosus ophthalmicus being administered 15 min. prior to 13 mg/kg M. of 5% water solution of thiopental-sodium injected in the same sinus. Prior to and following anesthesia at the 1st, 3rd, and 24th hour and on the 4th and 7th day the blood was checked with regard to hemoglobin, erythrocytes, erythrocyte sedimentation rate, hematocrit, leukocytes and leukocyte formula, total protein and protein fractions, calcium, phosphorus, magnesium, sodium, potassium, chlorides, total and direct bilirubin, and fibrinogen. Hemoglobin, erythrocytes, and hematocrit were found to drop insignificantly mathematically. The rate of increase of the sedimentation did not fully correspond to the drop of the erythrocyte count. The increase in leukocytes was accompanied by transient neutrophilia, eosinopenia, and lymphopenia in the early hours following anesthesia. The changes in the total protein and protein fractions, fibrinogen, total and direct bilirubin, and the other element indices referred to were shown to be close to the physiologic levels.
