ACID-BASE STUDIES IN ELECTIVE CAESAREAN SECTIONS DURING EPIDURAL AND GENERAL ANAESTHESIA

Gordon S. Fox; Germain L. Houle

RésuméNous avons étudié trois groupes de 13 malades et nouveaux-nés au cours de césariennes électives faites sous anesthésie avec N2O, O2 et épidurale. La moitié du groupe fait à l’épidurale a reçu de l’oxygène additionnel par masque.Nous avons noté les paramètres suivants: Acide-base, score Apgar, le délai du début de la respiration.Pour la césarienne élective, l’analgésie épidurale semble être l’anesthésie de choix. Le groupe des enfants nés sous épidurale a un degré d’acidose inférieur et une meilleure oxygénation que le groupe né sous anesthésie générale.L’addition d’oxygène augmente les tensions d’oxygène dans la veine ombilicale et dans le sang artériel, ce qui constitue une réserve additionnelle importante d’oxygène.

Transmission of lidocaine hydrochloride across the placenta during Caesarian section.

Gordon S. Fox; Germain L. Houle

SummaryTwo per cent lidocaine with 1:200,000 epinephrine was used for lumbar epidural analgesia in nineteen caesarian sections. Maternal and foetal blood lidocaine concentrations were obtained. Maternal uptake, placental transmission, and foetal metabolism of lidocaine are discussed.

Concentration of lidocaine hydrochloride in newborn gastric fluid after elective caesarean section and vaginal delivery with epidural analgesia

Sanjay Datta; Germain L. Houle; Gordon S. Fox

SummaryLidocaine concentrations were measured after vaginal delivery or Caesarean section with epidural anaesthesia in samples of maternal and umbilical blood and in newborn gastric contents. The pH of the gastric aspirate was also determined in a number of neonates. Gastric lidocaine concentrations were higher and the pH was lower after vaginal delivery in comparison to Caesarean section. A significant inverse correlation exists between gastric pH and gastric lidocaine concentration. Neonate gastric lidocaine concentration was significantly higher than in maternal or umbilical venous plasma after vaginal delivery, but not after Caesarean section. Due to these differences, gastric lavage for the treatment of neonatal lidocaine intoxication may be more beneficial in reducing foetal systemic local anaesthetic concentration after vaginal than after elective abdominal delivery.RésuméSuivant un accouchement ou une césarienne sous anesthésie péridurale, la concentration de lidocaine a été estimée dans le sang de la mère et du cordon ombilicale ainsi que dans les secretions gastriques du nouveau-né. Le pH des sucs gastriques a aussi été évalué chez un certain nombre de nouveau-nés. La concentration gastrique de lidocaine a été plus élevée et le pH plus bas dans les accouchements que dans les césariennes. Une correlation inverse existe entre le pH des secretions gastriques et la concentration gastrique de lidocaine. La concentration gastrique de lidocaine était plus élevée de façon significative dans les échantillons sangins de la mère et de la veine ombilicale après l’accouchement mais non suivant une césarienne. A cause de ces différences, le lavage gastrique au pour le traitement de l’intoxication au lidocaine du neuveau-né serait plus efficace à diminuer la concentration systemique de l’anesthesique local après un accouchement que suivant une césarienne.

Intrauterine fetal lidocaine concentrations during continuous epidural anesthesia

Gordon S. Fox; Germain L. Houle; P.D. Desjardins; Gilles Mercier

Abstract Twenty-two patients were given epidural analgesia with the use of one per cent lidocaine hydrochloride with 1:200,000 epinephrine for labor and delivery. Maternal and fetal blood were analyzed for lidocaine concentration. Maternal blood concentration fell in the range of 0.2 to 2.4 μg per milliliter, while intrauterine fetal lidocaine concentrations were in the range of 0.1 to 1.0 μg per milliliter, that is, far below the threshold for fetal toxicity. These findings provide further evidence for the safety of epidural analgesia for labor and delivery.

TRANSMISSION OF CARBONATED LIDOCAINE ACROSS THE PLACENTA DURING CAESAREAN SECTION

Germain L. Houle; Gordon S. Fox; Michael G. Torkington

RésuméLa lidocaine carbonatée employée pour l’anesthésie péridurale pendant la césarienne élective est un agent qui est certain de produire une analgésie maternelle qui sera rapide. Même si les niveaux sanguins de la mère et du fetus sont un peu plus élevés qu’avec la lidocaine conventionelle, les concentrations sanguines sont encore beaucoup moins que la dose toxique chez la mère et le fetus.

Anesthesia for Cesarean Section: Further Studies

Gordon S. Fox; J. B. Smith; Y. Namba; R. C. Johnson

This study was designed to re-evaluate neonatal condition at birth following elective cesarean section performed with epidural anesthesia and a modified technique of general anesthesia. Two groups of 20 patients were studied. Twenty received epidural anesthesia with 2 per cent lidocaine-carbon dioxide-epinephrine, and 20 patients were given general anesthesia. Modifications of our previous general anesthetic technique included the administration, to the mother, of high inspired concentrations of oxygen (66 per cent) prior to delivery, short induction-to-delivery intervals, and positioning of the mother in a 20 degrees left lateral tilt position. No significant differences in oxygen tension and acid-base balance in umbilical venous and arterial blood were demonstrated between the two sets of neonates. One-and five-minute Apgar scores and time to sustained respiration were similar in both groups. Our observations of the infants immediately after delivery led us to conclude that either anesthesia technique is acceptable for elective cesarean section.
