RESUMO
PURPOSE: To prevent hemodynamic and respiratory changes that are likely to occur during cementation in partial hip prosthesis by prophylactic use of pheniramine maleate and dexamethasone. METHODS AND MATERIALS: The study included 40 patients aged between 60 and 85 years with an American Society ofAnesthesiologists (ASA) grade of II-III who underwent partial hip prosthesis. Just after spinal anesthesia, 4 mL normal saline was pushed in patients in Group S, whereas 45.5 mg pheniramine maleate and 8 mg dexamethasone mixture was pushed intravenously in a total volume of 4 mL in patients in Group PD. RESULTS: Amounts of atropine and adrenaline administered after cementation were significantly higher in Group S than in Group PD (P < 0.05). There was a significant difference between SpO2 values before and after cementation in Group S; SpO2 value was lower after cementation (P < 0.05) except for 1. min after cementation. SpO2 value increased 1 min after cementation (P = 0.031) CONCLUSION: Prophylactic use of pheniramine maleate and dexamethasone in partial hip prosthesis led to an increase in SpO2 value and a decrease in the utilization of adrenaline and atropine after cementation.
