Alcohol 70% Versus Chlorhexidine 0.5% in the Spinal Anesthesia Skin Antissepsis

2016-07-15 01:23:22 | BioPortfolio


Context: The neuraxial blocks, spinal anesthesia and epidural anesthesia are among the most frequently performed procedures worldwide, and despite the advancements of medical equipment, remain dependent on experience and practice of the anesthesiologists. Although antisepsis takes part of the daily routine, there are still no solid scientific evidence of the most appropriate antiseptic for these procedures.

Objective: To compare the 70% alcohol and 0.5% chlorhexidine alcohol solution in skin antisepsis for the neuraxial blocks.

Methods: This is a clinical trial, a prospective, randomized study. There will be selected, consecutively, 70 patients candidates for neuraxial blocks. Patients will be randomly assigned to group A (n = 35), in which the antisepsis will be performed with alcohol 70%, and to group B (n = 35), in which the antiseptic will be performed with the 0.5% chlorhexidine in alcoholic solution. Samples will be collected with swabs in an area of 25 cm² for bacterial cultures three times: in pre-antisepsis moments, in the second minute after antisepsis, and immediately after the puncture. The number of colonies forming units per square centimeter (CFU / cm²) will be counted. The data will be analyzed statistically.

Medical and Biotech [MESH] Definitions

The destruction of germs causing disease.

Procedure in which an anesthetic is injected directly into the spinal cord.

A local anesthetic of the amide type now generally used for surface anesthesia. It is one of the most potent and toxic of the long-acting local anesthetics and its parenteral use is restricted to spinal anesthesia. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1006)

A potent local anesthetic of the ester type used for surface and spinal anesthesia.

Abnormally slow pace of regaining CONSCIOUSNESS after general anesthesia (ANESTHESIA, GENERAL) usually given during surgical procedures. This condition is characterized by persistent somnolence.
