INTRODUCTION. Subarachnoid anesthesia with Bupivacain is frequently used for inguinal herniorrhaphy. OBJECTIVE. To describe the use of selective hypobaric intradural anesthesia plus Fentanyl for unilateral inguinal herniorrhaphy. METHODS. A prospective, longitudinal and descriptive study was conducted in 100 patients selected for surgery of unilateral inguinal hernia in «Dr. Carlos J. Finlay» Central Military Hospital from January, 2006 to December, 2007. Selective hypobaric subarachnoid anesthesia using 0, 25% Bupivacaine plus 25µg Fentanyl was used. Motor blockade, quality and sensitive blockade level were assessed. RESULTS. In the blocked half of the body, the 68% achieved a motor I blockade level, remainder patients achieved a motor II blockade level; in the non-blocked half of the body it was null or IV level; quality of sensitive blockade was good in all cases and the sensitive level between D-8 and D-10. Mean values for heart rate and blood pressure were within those given as normality quota, hemodynamic stability was similar or higher to 98 and the 6 % of patients had the following complications: low blood pressure and urinary retention. CONCLUSIONS. The anesthetic technique used produces a scarce motor blockade, a appropriate quality of sensitive blockade, insufficient hemodynamic repercussion, and a minor incidence of complications.
