“…Among such host factors, blood flow in the target tissue is an important determinant for the survival of tumor cells [4,5,10]. We have shown recently that pneumoperitoneum using CO 2 with intraabdominal pressure up to 15 mmHg has little influence on tissue blood flow in various intraabdominal organs [11]. However, preliminary data from this study suggested that the peritoneum responded differently to some extent.…”

“…Low insufflations pressure in group A might attributed to the unaltered plasma sodium, potassium and chloride as reported by Yavuz et al 22 Furthermore, CP maintained for only 30 minutes in animals of the present study might be insufficient to inflict any changes. 23 Two cytosolic enzymes ALT and AST are mostly used to evaluate hepatic function.…”

Eighteen female mongrel bitches, equally divided into three groups (A, B and C) were subjected to CO 2 insufflation at 6, 10 and 14 mm Hg pressure gradient respectively to study the physiological changes of capnoperitoneum during laparoscopy. Optimum visualization of internal organs during laparoscopy was achieved at 10 and 14 mm Hg of CO 2 pressure gradient. The physiological effects were more pronounced at 14 mm Hg of CO 2 pressure gradient. Marked increase of respiration rate in correlation with increased pCO 2 and decreased pO 2 was observed in the group C. Bradyarrhythmia was observed in all three groups, however, myocardial ischemia or hypoxia as reflected through S-T segment depression and elevation was more pronounced in 14 mm Hg of CO 2 pressure gradient (group C). Alteration of liver function was within the physiological range in the animals of all the three groups. Physiological stress was remained significantly higher with 14 mm Hg intra-abdominal pressure. In conclusion, 10 mm Hg of CO 2 was found most suitable pressure gradient for laparoscopic examination in dogs.

“…Two experimental studies by Rosenthal et al 9 and Ben-Haim et al showed the increase in IAP to be followed by an increase in systolic, diastolic and mean arterial pressure, as well as in CVP. Th e study conducted by Yavuz et al 11 , inducing IAH in experimental conditions of pneumoperitoneum, showed that an increase in IAP caused an increase in arterial blood pressure, PaCO 2 and PaO 2 , whereas SpO 2 remained unchanged. Also, in the study by Barnes et al 12 it was demonstrated that at very high levels of IAP there was an increase in blood pressure, whereas heart rate did not change, PaO 2 decreased and PaCO 2 increased.…”

SUMMARY -Th e purpose of the study was to point to the importance of measuring intra-abdominal pressure (IAP) and of early recognition of the consequences of increased IAP on basic vital functions. Measurement of IAP via urinary bladder was conducted every 12 hours in 70 surgical patients with acute abdominal syndromes not previously operated on. Based on the measured IAP values, all patients were divided into groups of patients with normal IAP values (n=20) and patients with increased IAP values (n=50) . Vital functions and basic laboratory analysis were monitored and the values obtained were compared with IAP in both patient groups. A statistically signifi cant diff erence was found in body weight, body mass index, urine output, creatinine, urea, heart rate, partial pressure of oxygen (PaO 2 ) and partial pressure of carbon dioxide (PaCO 2 ) between patients with normal and increased IAP values. Th e increase in IAP values was found to be associated with an increase in PaCO 2 , respiratory rate, peak inspiratory pressure, central venous pressure, heart rate, Acute Physiology, Age and Chronic Health Evaluation II score, mortality rate, creatinine and urea values, and number of days of treatment in the intensive care unit. At the same time, the values of PaO 2, blood oxygen saturation, diuresis and abdominal perfusion pressure were declining. IAP measurement is an old, cost-eff ective, reliable technique that is easy to perform and should be applied in all high risk patients.

Effect of increased intraabdominal pressure on cardiac output and tissue blood flow assessed by color-labeled microspheres in the pig

Abstract: The level of IAP used in current practice (10-12 mmHg) appears to be safe with regard to hemodynamic variables and tissues blood flow; however, higher levels may induce a decrease in cardiac output and tissue blood flow.
