ALEGRE ANDRADE, Patricia  and  ARNICA GAMON, Alexander. NOREPINEPHRINE OR ETILEPHRINE IN THE TRATAMIENT OF INTRAOPERATIVE ARTERIAL HYPOTENSION FOR TOTAL HIP ARTHROPLASTY. Rev Cient Cienc Méd [online]. 2019, vol.22, n.2, pp.29-35. ISSN 2077-3323.

The frequent complication, after spinal anesthesia in hip arthroplasty is Intraoperative Arterial Hypotension, so the need to evaluate a vasopressor that is useful for this purpose. Objectives: To evaluate the use of norepinephrine and etilefrine for the prevention for intraoperative hypotension induced by spinal anesthesia in patients undergoing total hip arthroplasty. Methods: Clinical trial, simple blind, transverse and prospective. 38 patients of both sex, age 60 to 85 years, ASA II-III, spinal anesthesia and accept to participate in the study. Exclusion criteria: age <60 and> 85 years, ASA IV-V, general anesthesia, hypertension and uncontrolled heart disease. Assigned in 2 groups:group E (Etilefrine 2 mg bolus IV) and group N (Norepinephrine infusion 0.03 to 0.05 mcg/ kg/ min IV). The statistical analysis was performed student T. Results: Age in group E: 68 years and group N 69.94 years. Mean arterial pressure baseline (group E): 74.3 mmHg, y (group N): 72.4 mmHg, Statistical significance p value <0.05 after administration of local anesthestics. In group E, the baseline heart rate is 73 beats when using ethylephrine up to 95 beats. Group N: baseline of 70 and descent of 10 beats when the norepinephrine infusion is started. The Statistical significance (p value <0.05) in three moment (heart rate with vassopresor, durant surgery and end surgery). Conclusions: Use of norepinephrine in infusion maintains hemodynamic stability within normal ranges. There were no incidents of peripheral vasopressor use.
