Background: General anesthesia could be accompanied by changes in hemodynamic parameters (arterial blood pressure, heart rate, rhythm, central venous pressure, and venous blood pressure) that would result in altered intracranial pressure. In deep anesthesia the brain perfusion is dependent on blood pressure. The present study was conducted to determine the effects of neurosurgery on hemodynamic parameters in Naghavi Hospital in Kashan.
Materials and methods: This quasi-experimental study was performed on 112 patients. Systolic and diastolic blood pressure, and cardiac rhythm and rate were measured. Then the influence of sex, age, type of operation, duration of surgery and patient’s position on aforementioned parameters were evaluated.
Results: The study population included 70 males and 42 females, most of whom aged ≥ 40 years. Hemodynamic changes were more apparent among males. Meanwhile, age of ≥ 40 years, spinal surgery, prone position, and operations of more than 2-hour duration were associated with greater hemodynamic changes. Changes in systolic and diastolic blood pressure during induction was significantly differed regarding the duration of operation and patient’s position.
Conclusion: Hemodynamic changes are common in neurosurgical operations. These are different according to the type and duration of surgery and patient’s position. Further studies are highly recommended.
