Throughout this page you will find the definitions to the terms used throughout this website.

The definitions were taken from a variety of dictionaries, and medical web sites.

 

DEFINITIONS:

Epidural Anesthetic:

Anesthetic injected in the epidural space surrounding the fluid-filled sac (Dura) around the spine which partially numbs the abdomen and legs (Medterms.com Dictionary)

Bupivacaine:

Also known as (Sensorcaine, Marcaine), It is a narcotic used in epidural anesthesia and is classified as a local anesthetic (see Bupivacaine)

NCS Toxicity:

Central Nervous System toxicity occurs when excessive blood levels occur. It is caused by the injection of local anesthetic in the epidural vein (see CNS link)

CVS Toxicity:

Cardiovascular System Toxicity occurs when excessive blood levels occur but is more serious. It is most common with the use of Bupivacaine (see CVS link)

Fetal Bradycardia:

Fetal Bradycardia is the term used when the baby's heart rate goes under 100 beats per minute. Can become serious if lengthily.

Fetal Tachycardia:

Fetal Tachycardia is the term used when the baby's heart rate is too high. Can be sign of distress.

Cardiac Arrhythmia:

Arrhythmias are caused by a disruption of the normal functioning of the electrical conduction system of the heart.

Intrathecal:

This term means injection of drug into the fluid surrounding the spinal cord. (Medterms.com)

Hypoxia:

Concentration of oxygen in arterial blood that is less than normal.

Tinnitus:

"Ringing in the ears" or another noise that seems to originate in the ears or head.

Circumoral Numbness:

Numbness of mouth and tongue.

Myocardium:

The heart muscle

Diazapam:

Diazepam is a benzodiazepine with CNS depressant properties and a somewhat flatter dose-response slope than the sedative-hypnotic drugs

In humans, comparable blood levels of diazepam were obtained in maternal and cord blood indicating placental transfer of the drug. Diazepam may appear in human breast milk. (see diazapam link)

Thiopentone:

a short-acting Barbiturate (seditive). It is given by intravenous injection to produce general anaesthesia or as a premedication prior to surgery. Possible complications of thiopentone anaesthesia can include respiratory depression, laryngeal spasm, and thrombophlebitis. The drug is not used when respiratory obstruction is present.

Acidosis:

A condition in which the body fluids become more acidic, i.e. the pH is less than 7.4, and the capacity of the body to buffer hydrogen ions is diminished. A decrease in the elimination of carbon dioxide from the body gives rise to respiratory acidosis, while a deficiency of hydrogencarbonate results in metabolic acidosis (acidity of body fluids is abnormally high).
