[The beginning of anesthesia].

On October 16, 1846, the first public demonstration of etherization, at the Massachusetts General Hospital, Boston, illustrated the rise of Inhalational Anaesthesia. Pioneers were: Hickman, Wells, Morton, Davy and Long. Anaesthesia was considered an American invention. Thereafter, the development of new molecules (cocaine, hexobarbital) which can be administered by others ways (spinal puncture, intravenous injections) allowed new methods of anaesthesia to be achieved. Thus, three successive periods have illustrated the Story of Anaesthesia: Inhalational Anaesthesia (1844), Local Anaesthesia (1860), Intravenous Anaesthesia (1932).

[Perioperative analgesia in the surgery of peripheral veins].

The analgesic efficiency of Propacetamol and Acid Niflumique for post-operative pain in the recovery room, was studied in two groups of 27 patients who had undergone stripping. Pain scores recorded were obtained with the pain ruler during two hours after intravenous injection of Propacetamol (30 mg/kg-1). The analgesic efficiency of Propacetamol is always good. We have not any benefit to purpose acid nifluril before surgery.

[Hemodynamic effects of intranasal nifedipine during clamping of the abdominal aorta].

The haemodynamic changes due to cross-clamping of the abdominal aorta below the renal arteries were studied in ten patients. Anaesthesia was induced with thiopentone and maintained with fentanyl and vecuronium and inhalation of 60% nitrous oxide in oxygen. At the fifth minute, clamping increased mean arterial pressure (Pa) by 11%, systemic vascular resistance (Rsa) by 26% and decreased cardiac output (CO) by 20%. Nifedipine was administered intranasally at this time. Heart rate remained unchanged; mean pulmonary arterial and mean pulmonary wedge pressures were slightly decreased. Pa and Rsa fell to significantly lower levels between the fifth and fifteenth minutes (24 and 43% respectively). Although CO increased by 28%, this was not significant. The administration of intranasal nifedipine during anaesthesia was well tolerated. This study demonstrated that intranasal nifedipine prevented adverse haemodynamic effects of cross-clamping of the aorta below the renal arteries.

[Determination of thresholds of external cardiac pacing during anesthesia].

The efficacy of transcutaneous pacing was studied in 33 patients during general anaesthesia. The temporary pacing was effective in all cases. Stimulation thresholds ranged from 85 to 150 mA (mean : 110 +/- 17). In all 33 patients, external pacing was effective in producing a pulse without significantly reducing arterial pressure. Stimulation thresholds were only influenced by electrode position; age, weight, thoracic diameter and cardiothoracic ratio did not have any effect on them. No adverse effects of transcutaneous pacing were recorded. Transcutaneous pacing can be an alternative to transvenous right ventricular endocardiac pacing in the operating room in some circumstances.

[Spontaneous perforation of the rectum. One case (author's transl)].

A 48-year-old man, operated upon with a diagnosis of perforation of a hollow viscus, in whom a spontaneous perforation of the rectum was discovered. Such perforations are rare since only 36 cases have been reported in the literature. The mechanism is unknown and various factors have been suggested, including increased pressure or local ischaemia. Treatment is rendered difficult by local infection and the frequently fragile general condition of the patients.
