Effect of body habitus and parity on insufflated CO2 volume at various intraabdominal pressures during laparoscopic access in women

The role of abdominal compliance, the neglected parameter in critically ill patients — a consensus review of 16. Part 2: measurement techniques and management recommendations

“…It has been observed that the compliance of the abdominal cavity decreases when additional volume is added to the abdominal cavity [37]. This was confirmed clinically by McDougall et al and Abu-Rafea et al who examined 41 and 100 patients respectively during laparoscopy with CO 2 pneumoperitoneum [38,39]. The linear abdominal volume-pressure curve changed to a rather exponential shape when a pressure of 15 mm Hg was achieved by insufflating 3 and 4.5 L of CO 2 in each study (Fig.…”

“…The linear abdominal volume-pressure curve changed to a rather exponential shape when a pressure of 15 mm Hg was achieved by insufflating 3 and 4.5 L of CO 2 in each study (Fig. 9, derived from [38,39]). In their studies, the initial abdominal compliance at the beginning of the CO 2 inflation varied between 333 and 400 mL (mm Hg) -1 and at higher IAV (with corresponding IAP above 15 mm Hg) the C ab dropped to 60 and 90 mL (mm Hg) -1 respectively [38,39].…”

The Neglected Role of Abdominal Compliance in Organ-Organ Interactions

“…During laparoscopy with limitation of insufflation pressures at 12 to 15 mmHg, the IAV did not reach a critical point at which an exponential increase in IAP occured [13]. As discussed above, the initial phase of the PV curve may indeed be linear (as observed during laparoscopy) but the remaining part is curvilinear or rather exponential [13][14][15]. Because of this exponential relationship, it is important to know both the shape and the position on the curve, as the actual position will determine the corresponding C ab .…”

The Effects of Different Intraabdominal Pressure Protocols in Laparoscopic Procedures on Oxidative Stress Markers and Morphology in Rat Ovaries

“…Abu-Rafea at el. indicated that a higher CO 2 volume is required to estabilish appropriate pneumoperitoneum in tall, overweight and parous women at IAPs of 20-30 mm Hg at the beginning of laparoscopy [19]. Madl and Druml [20] previously reported that an IAP of no more than 10 mm Hg would not cause any major hazardous effects, but an IAP exceeding 12 mm Hg could result in inflamation of the tissues, including processes like leukocyte migration, a release of cytokines, increased formation of reactive oxygen intermediates, etc.…”
