Use of infra-red carbon dioxide analysis during general anaesthesia in the horse.

The carbon dioxide content of respiratory gases may be monitored by the use of an infra-red carbon dioxide analyser. The technique allows continuous and non-invasive recording of important information concerning the ventilatory, circulatory and metabolic states of the anaesthetised horse. Some of the monitoring capabilities of a carbon dioxide analyser (capnograph) are reviewed with illustrations from cases anaesthetised in the authors' clinic. Technical faults in the anaesthetic apparatus and the connections with the "patient" could be readily detected and emergency situations immediately recognised and treated without delay. Use of the apparatus allowed refinement of the anaesthetic technique and greatly augmented the safety of general anaesthesia.

[A simple modification for the electrochemical oxygen analyzer to improve accuracy during prolonged closed system anaesthesia (author's transl)].

A simple modification of the condenser used with the electro-chemical oxygen analyzer (Dräger BioMarine OA202 R) consists of filling the distal chamber with hygroscopic silicagel. This prevents condensation of water vapour on the sensor thus allowing the accuracy during prolonged closed system anaesthesia to remain nearly unaffected (fade less than 0.5%/h).

Increased plasma bromide concentration in the horse after halothane anesthesia.

A long-lasting increase of the plasma bromide concentration was found in 25 horses after clinical halothane anesthesia. The plasma bromide concentration was significantly (P less than 0.005) increased at the end of anesthesia. In 18 horses, peak values were reached between 48 and 72 hours after anesthesia. Eighteen days after horses had been anesthetized, the plasma bromide concentration remained significantly (P less than 0.005) increased. Significant correlation was not found between the total dose of halothane and the plasma bromide concentration. In 1 horse reanesthetized with halothane 4 days after initial halothane anesthesia, the plasma bromide concentration increased to high concentrations.

Introduction to the quantitative technique of closed circuit anesthesia in dogs.

In humans, anesthetic uptake in a closed system with constant arterial concentration has been shown to be inversely proportional to the square root of time. A practical method for quantitative dosage of volatile anesthetic was derived from this. The method was evaluated in nine dogs anesthetized with a closed circle system using halothane and isoflurane. A unit dose (UD) of anesthetic was calculated in milliliters of vapor which was converted to milliliters of liquid and repeatedly administered into the expiratory limb between the squares of integer units of time (0-1, 1-4, 4-9 minutes, etc). The UD was derived as follows: UD = 2 f MAC X lambda B/G X 2 (kg)3/4, where f MAC was the desired alveolar concentration, lambda B/G the blood-gas partition coefficient, and 2 (kg)3/4 was an approximation of cardiac output. The method resulted in a stable plane of anesthesia and permitted continuous monitoring of O2 consumption. There was no significant difference between predicted and measured values of O2 consumption, cumulative doses, or alveolar concentrations at 9 and 16 minutes of anesthesia.
