Antimicrobial prophylaxis for major head and neck cancer surgery with piperacillin and ornidazole.

A prospective study in 53 eligible patients, undergoing major head and neck cancer surgery was carried out to assess the combination of an ureido penicillin, piperacillin with a nitro imidazole agent, ornidazole, in order to prevent post-operative general and wound infections. Both antibiotics were administered for five days. Each patient had piperacillin 4 gm every eight hours and ornidazole 1 gm every 24 hours.

[Pharmacokinetics of continuous infusion of etomidate in cirrhotic patients].

The pharmacokinetics of etomidate were studied in 9 control subjects (with normal liver function) and in 5 patients with cirrhosis scheduled for gastro-intestinal surgery. Anaesthetic induction included an initial bolus of etomidate 0.3 mg.

[Intubation in otorhinolaryngologic surgery: propofol versus propofol-suxamethonium].

This study was carried out to assess the conditions of intubation in head and neck surgery when using propofol alone or associated with suxamethonium. Sixty patients were randomly allocated in two groups of 30. Group I was given 3 mg.

[Anesthesia in high class athletes].

A case of general anaesthesia in a 49 year old male, high level specialist in triathlon, is reported. At the preoperative assessment, the patient had a sinus bradycardia of 45 b.min-1.

[Ambulatory anesthesia and induced abortion. Comparative study of propofol-alfentanyl and ketamine-midazolam combinations].

The use of propofol alone or with alfentanil in the day-case anaesthesia for abortion was compared with that of ketamine with midazolam. Two hundred young women were assigned to two successive series of two groups each. The four groups were: group 1 (2 mg .

Maternal and fetal concentration of morphine after intrathecal administration during labour.

Twenty-five healthy women in labour received morphine 1-1.75 mg in normal saline intrathecally. The residual pain was evaluated on a scale from 0 to 5 at 10 min (score 2.

[Effects of flunitrazepam on intraocular pressure (author's transl)].

Though ophthalmologists operate upon patients that are in a debilitated state, a general anesthesia has to be employed with increasing frequency. Flunitrazepam, known to possess good cardiovascular tolerance, was studied to evaluate its effects on intraocular pressure in 34 unselected patients undergoing 41 operations under general anesthesia, usually 41 operations under general anesthesia, usually for retinal detachment or cataract. Ocular pressure was normal in all cases before surgery, but a history of chronic respiratory insufficiency was obtained in 8 cases and of cardiovascular disease in 18.

[Pharmacoclinical competition between the benzodiazepines. Demonstration with diazepam and flunitrazepam in man].

While using a new benzodiazepines flunitrazepam by the intravenous route in ordinary anethesia a competitive action with another benzodiazepine which is being used for the last 15 years, namely diazepam, was demonstrated for the first time in man. This study on 170 patients operated for ear, nose and throat conditions demonstrated this phenomenon, confirmed it and it was possible to reproduce the effect. The interaction is mainly characterized by: - A reduction of the effects of flunitrazepam (less profound sleep, even wakefulness with a waking patient who could talk and could react to pain).

[The effect of surgical incisions on ventilatory function].

Normal surveillance was extended to include respiratory function tests (Vital capacity, FEV1, Maximum Breathing Capacity) on 40 post-operative patients. The reduction relative to pre-operative values on the 1st day after operation was of the order of 60 p. 100 for high abdominal incisions, 35 p.
