Nitrous oxyde

BACKGROUND: The administration of an equimolar mixture of nitrous oxide and oxygen (N2O) is recommended during painful procedures. However, the evaluation of its use during physiotherapy after surgery has not been reported, although pain may hamper physiotherapy efficiency. This study investigated whether the use of N2O improves the efficacy of post-operative physiotherapy after multilevel surgery in patients with cerebral palsy. METHOD: It was a randomized 1:1, double-blind, placebo-controlled study...

The newborn's vitamin B12 storage exclusively comes from placenta transfer, later from animal food. We relate 3 observations of infants (3-11-13 months) with failure to thrive, anorexia, vomiting and for the two olders refusal of weaning, associated with psychomotricity regression and hypotony. Blood cell count showed a macrocytosis without anemia (case 2-3) and a severe microcytic anemia for the first case caused by a mild alpha-thalassemia, with megaloblastic bone marrow. Vitamin B12 levels were very low associated with increased methylmalonic acid and homocysteine serum levels which confirm the diagnostic ...

INTRODUCTION: Despite the progress in surgical and anaesthetic management, decreased renal function is still observed after abdominal infrarenal aortic surgery and remains an important problem in postoperative period. Although data regarding the efficacy of perioperative renal protection are conflicting, it is widely believed that renal protection before aortic cross-clamping is beneficial and therefore is commonly used. The aim of this study was to evaluate the impact of renal protection in patients undergoing elective infrarenal aortic surgery (1ARS)...

The authors have performed 66 (cranial or spinal) operations with electro-anaesthesia supplemented by neuroleptics and pancuronium. In this technique, which respects the necessities of neurosurgical anaesthesia, analgesia is produced by means of Limoge's rectified high frequency currents. The protocol consists of: induction by a neuroleptic, application of the electrical current, intubation with benzodiazepin and succicurarium, controlled ventilation with a 50 p. cent oxygen/50 p. cent nitrous oxyd mixture and curare as required...

Neuronal responses to noxious stimulation applied on the skin of the limbs or of the tail were studied in the somatosensory cortex of rats under Fluothane/nitrous oxyde anesthesia. Among 694 neurons, 56 responded to noxious stimulation only and 35 to noxious as well as non-noxious stimulation. The receptive fields of these neurons were often larger than those of neurons recorded during the same penetration but unresponsive to noxious stimulation. They were able to encode stimulus parameters such as temperature of a hot water bath or size of the skin area stimulated...

A self made connection device with an injector of 1.5 mm in diameter and connections for the measurements of the end tidal CO2 (Datascope 500 CO2 Analyzer), expired tidal and minute volumen (Dr¿ger Spirolog), and armoured tracheal tube nr. 22 with cuff (Rüsch), has been used in 25 unselected patients submitted to diagnostic laryngoscopy. The patients have been ventilated with Wolf Injectomat 2025 with incorporated Bird's Nitrous Oxyde/Oxygen blender and general anesthesia with i.v. hypnoticum (Penthotal or Hypnomidate), analgeticum (Fentanyl) and muscle relaxant (Curalest) has been used...

One hundred unselected adult cardiac patients operated on with extracorporeal circulation (ECC) underwent analgesic anesthesia. In half of the cases, the analgesic used was morphine and for the others fentanyl. Anesthesia was completed with flunitrazepam, pancuronium, nitrous oxyde and a neuroleptic if necessary. Operative, postoperative and recuperation periods were very satisfactory and very the same in both series. Due to its small administrated dosage (average 1.22 mg/kg) the secondary effects of morphine remained discrete...

Comparative studies were performed on the spasmolytic and hypotensive effects of pentacyanoferrates with different ligands (NO, NO2, NOS, NH3, H2O) and of hexacyanoferrates and other nitrosyl compounds. Besides sodium nitroprusside, the nitro and thionitro complexes in equimolar doses were found to cause hypotension and relaxation of the aortic strip of rabbits contracted by adrenaline and spasmolytic effects on the contracted guinea pig ileum. The liberated nitrosyl cation or its secondary product, nitrous acid, is thought to be responsible for the pharmacodynamic effects of these complex compounds...

Through a retrospective study of 81 anaesthesias for primary excision with immediate grafting (performed within the first 72 hours after burning), the authors, using in most of the cases an anaesthetic procedure including neuroleptanalgesia and nitrous oxyde, with controlled ventilation, tried to determine: --the incidence of such a type of anaesthesia on the patient condition, --the period during which anaesthetic risk is the least. Studies of hemodynamic, respiratory and thermic changes, related with anaesthesia, and a study of coagulation changes, related with surgical procedure, have been performed...

Immune depression occurs after general anaesthesia. It is related to depression of serum factors after anesthesia with ether or chloroform, or secondary to depression of antibody-producing cells after anaesthesia with halothane, nitrous oxyde or Pentothal. This immune depression augments proneness to bacterial and viral infection and to malignant disease.
