667 cases inclusively 27 twin-births are evaluated in a retrospective study on the anesthesias administered in cesarean section (CS) from 1975 to 1983. The applied induction anesthetics hexobarbital, ketamine (Ketanest), propanidid (Sombrevin), etomidate (Radenarcon) and epidural anesthesia with bupivacaine (Marcaine) have been compared with each other concerning the Apgar scores of the newborns. Significant more depressed newborns have been found both in the hexobarbital group and to a low degree in the ketamine group...

The threshold of the acoustically elicited stapedial reflex was measured in 45 persons with normal hearing aged 13-34 years. The intravenous barbiturate given for induction of general anaesthesia was found to raise the reflex threshold by an average of 15 dB. Ketanest and Halothane raise the reflex threshold by an average of 24 dB and 28 dB respectively. The ipsilateral reflex response was altered less by general anaesthesia than the contralaterally evoked response. The stapedial reflex can thus be measured under general anaesthesia if sedation fails to control disturbed and severely handicapped children...

In rabbits the blood glucose and consequently the aqueous humour glucose levels were increased under general anaesthesia by Ketanest-xylazine. Between 60 and 90 min of the general anaesthesia the average blood glucose levels were found to be three times and those of the aqueous humour twice the normal values. After more than 75 min of anaesthesia the glucose levels tended to be further elevated.

The semisynthetic third generation cephalosporin cefmenoxime was injected through the pars plana into the mid-vitreous in seven rabbit eyes. The drug dosage varied between 0.5 and 15 mg. Seven control eyes were injected only with 0.9% NaCl-solution. Electroretinography was performed before injection and 1 week post injection. The rabbits were anesthetized by intramuscular application of ketanine (Ketanest). Immediately after the second ERG the eyes were enucleated and prepared for both light and electron microscopy...

The concept of combined anaesthesia, the centrally-acting muscle relaxant guaifenesin (My 301) in a 5% solution with ketamine (and/or fentanyl) in addition to the inhalation of nitrous oxide and halothane is based upon the principle of "balanced anaesthesia". Guaifenesin amplifies the effect of several anaesthetics, which complement one another, allowing the dosage to be decreased and thereby reducing the cardiovascular stress. To induce anaesthesia, the combination of a cataleptic anaesthetic (ketamine = Ketanest, Ketolar) and a centrally acting skeletal muscle relaxant (guaifenesin = Myolaxin, My 301) is used...

Propofol (Diprivan), a modern intravenous hypnotic, produces a reduction in both cardiac index (CI) and mean arterial pressure (MAP). Ketamine (Ketanest), a potent analgesic, in contrast, causes an increase in MAP and CI. The aim of the present study was to investigate whether the combination of propofol and ketamine can give better hemodynamic stability during the induction and maintenance of general anesthesia than propofol used with fentanyl, whose cardiodepressant actions may cumulate. METHODS. For induction of general anesthesia 10 patients (ASA I and II) each received 3-5 boluses of propofol (0...

The effect of various anaesthetics and of the manipulations of the hypothalamo-pituitary-adrenocortical system (hypophysectomy, adrenalectomy and lesion of the mediobasal hypothalamus) was studied on immunoreactive-ACTH levels in the plasma and in the cerebrospinal fluid in the rat. The anaesthetics used (Hypnorm, pentobarbital, urethan and Ketanest) were without effect on immunoreactive-ACTH concentration in the cerebrospinal fluid. Immunoreactive-ACTH was significantly decreased after hypophysectomy and elevated after adrenalectomy in both cerebrospinal fluid and plasma...

Injection of Epontol (7 mg/kg i.v.) to male healthy students caused a brief increase in plasma histamine concentration from 0.7 ng/ml to 3.0 ng/ml. Combined injection (7 mg/kg) and infusion of Epontol (21 mg/kg during 15 min) or combined injection of Epontol (7 mg/kg) and suxamethonium (0.5 mg/kg) caused a more prolonged appearance of histamine in plasma without higher maximum concentrations. During anaesthesia with ketamine (Ketanest), halothane or nitrous oxide the histamine concentrations in plasma remained unaltered...
