Fentanyl and 0,5 % bupivacaine in elderly patients with hip fracture operated on under subarachnoid anesthetic

Abstract

Background: the elderly patient is at a greater risk of hemodynamic instability and anesthetic complications during the perioperative period.Objective: to describe the hemodynamic stability in the elderly operated on for hip fracture using subarachnoid anesthetic, at the Ernesto Guevara de la Serna Hospital from January through December 2015.Methods: a prospective longitudinal study was carried out at the place and during the period herein mentioned. The study universe consisted of all the elderly patients with hip fracture, who underwent surgery to correct it. The sample was made up of 47 patients with ASA 2 and 3 physical statuses, who were operated on using subarachnoid anesthetic with doses of bupivacaine, 0,5 % 8 mg plus fentanyl, 25 mcg. Descriptive statistics was used by means of percentage analysis.Results: female patients prevailed in 70,21 %; 63,82 % belonged to the 76 to 85 age group; patients with ASA 2 physical status were more frequent with 68,1 %; 87,23 % showed stability of blood pressure; heart rate remained normal in 83 %; the most common side effect was mild pruritus, which occurred in 100 % of the cases, followed by drowsiness in 74,4 %.Conclusions: most of the elderly patients who were operated on for hip fracture under subarachnoid anesthetic using the combination of fentanyl, 25 mcg plus 0,5 % bupivacaine, 8 mg showed hemodynamic stability in terms of blood pressure and heart rate. All cases reported mild facial pruritus as an adverse effect.
