BACKGROUND The creation of pneumoperitoneum and Trendelenburg positioning during laparoscopic surgery are associated with respiratory changes. We aimed to compare respiratory mechanics while using intravenous propofol and remifentanil vs. sevoflurane during laparoscopic colectomy. METHODS SIXTY PATIENTS UNDERGOING LAPAROSCOPIC COLECTOMY WERE RANDOMLY ALLOCATED TO ONE OF THE TWO GROUPS: group ...

PURPOSE Cerebrovascular reactivity to carbon dioxide (CVR-CO2) reflects cerebrovascular reserve capacity, which is important in many brain disorders, including cerebrovascular and Alzheimer's diseases. Meanwhile, there is a relationship between CVR-CO2 and cognitive function. Therefore, the study is aimed at investigating the effects of sevoflurane versus propofol on CVR-CO2 during laparoscopic...

early detection of free air in the peritoneal cavity is vital in diagnosis of life-threatening emergencies, and can play a significant role in expediting treatment. we present a series of cases in which bedside ultrasound (us) in the emergency department accurately identified evidence of free intra-peritoneal air and echogenic (dirty) free fluid consistent with a surgical final diagnosis of a p...

The Effect of Low-Pressure Pneumoperitoneum with Active Evacuation on the Severity Shoulder Pain in Patients Undergoing Laparoscopic Cholecystectomy

Laparoscopic surgeries have become popular and are now widely used in gynecological procedures due to their minimally invasive nature. CO2 is create the pneumoperitoneum facilitate laparoscopic surgery. Pneumoperitoneum different positions can adverse effects on hemodynamics. Most of system human body affected including Cardiovascular pulmonary leading various complications. Complications inclu...

BACKGROUND Increased central venous pressure secondary to an increase in intraabdominal pressure has been reported during laparoscopic surgery. However, no study has yet determined the effect of pneumoperitoneum on cross-sectional area (CSA) of central veins by ultrasonography during laparoscopic cholecystectomy. Herein, we aimed to quantify changes in CSAs of internal jugular (IJV) and subclav...

PURPOSE Laparoscopic cholecystectomy has been accepted as an alternative to laparotomy, but there is still controversy regarding the effects of pneumoperitoneum on splanchnic and hepatic perfusion. We assessed the effects of different insufflation pressures on liver functions by using indocyanine green elimination tests (ICG-PDR). METHODS We analyzed 43 patients who were scheduled for laparos...

pneumatic rectosigmoid rapture is usually occurred following the inappropriate fun by direct entering a high volume of the air through the pneumatic device to the anus. such an event was reported for the first time in 1904 by stone. diagnosis and treatment of such injuries are often delayed because of some social limitations and preventing the patient form explaining the event. colon sigmoid ru...
