5% Lidocaine Hydrochloride and 7.5% Dextrose Injection, USP is indicated for the production of spinal anesthesia when the accepted procedures for this technique as described in standard textbooks are observed.

Lidocaine is contraindicated in patients with a known history of hypersensitivity to local anesthetics of the amide type. The following conditions preclude the use of spinal anesthesia:Severe hemorrhage, shock or heart blockLocal infection at the site of proposed punctureSepticemiaKnown sensitivity to the local anesthetic agent.

---

Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.

SPONDYLOMETAEPIPHYSEAL DYSPLASIA, SHORT LIMB-HAND TYPE --

Shock -- A pathological condition that can suddenly affect the hemodynamic equilibrium, usually manifested by failure to perfuse or oxygenate vital organs.

Communicable Diseases -- broad class of diseases whose causative agents may be passed between individuals in many different ways.

Infection -- Invasion of the host organism by microorganisms that can cause pathological conditions or diseases.

5% LIDOCAINE HYDROCHLORIDE AND 7.5% DEXTROSE INJECTION, USP FOR SPINAL ANESTHESIA SHOULD BE EMPLOYED ONLY BY CLINICIANS WHO ARE WELL VERSED IN DIAGNOSIS AND MANAGEMENT OF DOSE-RELATED TOXICITY AND OTHER ACUTE EMERGENCIES THAT MIGHT ARISE FROM SPINAL ANESTHESIA AND THEN ONLY AFTER ENSURING THE IMMEDIATE AVAILABILITY OF OXYGEN, OTHER RESUSCITATIVE DRUGS, CARDIOPULMONARY EQUIPMENT, AND THE PERSONNEL NEEDED FOR PROPER MANAGEMENT OF TOXIC REACTIONS AND RELATED EMERGENCIES (See also ADVERSE REACTIONS and PRECAUTIONS).

DELAY IN PROPER MANAGEMENT OF DOSE-RELATED TOXICITY, UNDERVENTILATION FROM ANY CAUSE AND/OR ALTERED SENSITIVITY MAY LEAD TO THE DEVELOPMENT OF ACIDOSIS, CARDIAC ARREST AND, POSSIBLY, DEATH. To avoid intravascular injection, aspiration should be performed before the local anesthetic solution is injected. The needle must be repositioned until no return of blood can be elicited by aspiration.

Note, however, that the absence of blood in the syringe does not guarantee that intravascular injection has been avoided. Spinal anesthetics should not be injected during uterine contractions since spinal fluid current may carry the drug farther cephalad than desired.
