Abstract |
As laparoscopic operation has become more widely practiced, the full spectrum of effects associated with this technique must be realized. The purpose of this study is to investigate the cardiovascular effects, blood gas changes and especially changes in respiratory variables during laparoscopic operation. We studied 10 patients undergoing elective laparoscopic cholecystectomy (group I) and another 10 patients undergoing elective laparoscopic salpingectomy (group II). In both groups, mean arterial pressure and PaCO2 were increased and pH was decreased. But there was no significant change in PaO2. The changes of respiratory variables in group I were not significant. But in group II, peak airway pressure was increased and compliances significantly decreased (p<0.05) owing to more head-down position. In condusion, patients who are undergoing laparoscopic operatian may require careful monitormg about hemodynamic changes, oxygenation and CO2 retention during anesthetic management. |
