title: The effect of surgical technique on hemodynamics, arterial oxygenation and pulmonary mechanics in radical prostatectomy operations.
abstract: OBJECTIVE
  The effects of surgical technique on respiratory mechanics, arterial oxygenation and hemodynamics in radical prostatectomy operation were investigated.
  
  
  METHODS
  The study was planned on ASA II-III, 40-65 years old, fourty patients scheduled for radical prostatectomy under general anesthesia. They were divided into two groups: perineal and suprapubic (Group P, n = 20; Group S, n = 20). Heart rate, mean arterial blood pressure, arterial oxygen saturation (SpO2), partial pressure of end-tidal carbon dioxide (PEtCO2), Peak inspiratory pressure (PIP), plato pressure (Pplato), partial pressure of oxygen in arterial blood (PaO2), partial pressure of carbon dioxide in arterial blood (PaCO2) values were evaluated at 10 minutes after induction. After the position applied for surgery in the 30.60 and 90th minutes, the Alveolar-arterial oxygen pressure gradient (P(A-a) O2), the ratio of physiologic dead space over tidal volume (VD/VT), arterial to end tidal CO2 gradient (P(a-et) CO2), static compliance (CS), dynamic compliance (CD) were assessed.
  
  
  RESULTS
  In the assessment of groups, there were not statistical differences about mean blood pressure, heart rate, SpO2, PetCO2, PaO2, plateau pressure, and P (A-a) values (p &gt; 0.05). Peak inspiratory pressure was higher in Group P. Peak inspiratory pressure and plateau pressure increased with CO2 insufflation in Group P. PaCO2 and P(a-et) CO2 were higher statistically significantly in Group 0. There was no difference in terms of the PetCO2 values. VD/VT ratios were statistically significantly lower in the Group P.
  
  
  CONCLUSIONS
  Suprapubic surgery was shown to improve oxygenation and respiratory mechanics without causing any hemodynamic side effect in radical prostatectomy operation.
