Physiologic Responses to Infrarenal Aortic Cross-Clamping during Laparoscopic or Conventional Vascular Surgery in Experimental Animal Model: Comparative Study

Table 3

Systolic volume (SV) and and systemic vascular resistance (SVR) in pigs anesthetized with sevoflurane, fentanyl, and vecuronium and undergoing aortic cross-clamping through laparotomy (Group I) or laparoscopy with (Group II) or without aortic cross-clamping (Group III).
