Abstract:
Objective To observe the effects of hyperventilation on jugular bulb pressure and optic nerve sheath diameter during RALRP. Methods Twenty patients undergoing elective RALRP were enrolled in this study. After hyperventilation of General anesthesia,we monitored and recorded changes of Heart rate(HR),mean arterial pressure (MAP),end-tidal carbon dioxide (ETCO2),arterial oxygen tension (PaO2),arterial carbon dioxide tension(PaCO2),peak airway pressure(PIP),JBP and ONSD in 5 minutes after intubation(T0),Trendelenberg posture in 15 minutes (T1),the established pneumoperitoneum in 30,60,90 minutes (T2,T3,T4) and termination of pneumoperitoneum in 15 minutes in supine position(T5)respectively. Results Compared with T0, JBP increased at T1 ~ T5(P < 0.05). ETCO2 and PaCO2 of T1 ~ T5 were lower than those of T0(P < 0.05)during hyperventilation. After establishment of Trendelenburg posture and pneumoperitoneum,PIP values increased at T1~T4 than that at T0 (P < 0.05),However,ONSD increased from T3 to T5 compared with T1 to T2 (P < 0.05). Conclusion Through over-ventilation,pneumoperitoneum and Trendelenburg posture,JBP and PIP can increase, and ONSD becomes wider evendually.
