OBJECTIVE
To evaluate the renal sodium-potassium adenosine triphosphatase (Na+/K+ATPase) activity, kidney morphology, and the probable protective effects of 2 different anesthetic agents used during pneumoperitoneum (PP).
METHODS
The study was performed at Gazi University Experimental Research
The purpose of this study was to find out the impact of acute respiratory acidosis on serum potassium level during laparoscopy. The study was performed on ninety patients who underwent laparoscopic surgery. Ventilation parameters were kept constant throughout the study. Samples for assessment of
Hyperkalaemia with ECG changes had been noted during prolonged carbon dioxide pneumoperitoneum in pigs. We have compared plasma potassium concentrations during surgery in 11 patients allocated randomly to undergo either laparoscopic or open appendectomy and in another 17 patients allocated randomly
OBJECTIVE
To evaluate the effects of pneumoperitoneum with carbon dioxide and helium on renal function and morphology in a rat model.
METHODS
Twenty four rats were randomized into three groups (n=8): gasless insufflation ('open', Pressure=0 mmHg), carbon dioxide pneumoperitoneum at 12 mmHg, and
OBJECTIVE
There are no studies associating ventilatory mode effects on renal repercussions during pneumoperitoneum. This study aimed at evaluating pneumoperitoneum-induced renal hemodynamics and function changes in dogs under volume and pressure controlled ventilation.
METHODS
This study involved 16
The aim of this work was to study the cardiovascular effects, the acid-base balance in serum electrolytes and chlorides in 50 patients during diagnostic laparoscopy, comparing the use of CO2 and N2O for pneumoperitoneum. The CO2 group showed a significant decrease in pH, a significant increase in
BACKGROUND
The unique positioning of the patient at steep Trendelenburg with prolonged and increased intra-abdominal pressure (IAP) during robotic radical prostatectomy may increase the risk of splanchnic ischemia. We aimed to investigate the acute effects of IAP and steep Trendelenburg position on
BACKGROUND
Peritonitis from small bowel perforation is associated with prohibitive morbidity and mortality rates. The aims of our study were to review our institution's experience in the surgical management of small bowel perforation and to identify factors that could predict morbidity and
BACKGROUND
The effects of increased intra-abdominal pressure (IAP) and volume expansion on renal function in the rat were studied to gain more knowledge of the oliguria seen during laparoscopic procedures and to reduce the detrimental renal effects of IAP.
METHODS
IAP was elevated to 5 or 10 mmHg by
Rupture of the urinary bladder at the time of parturition occurred in a 2 year old Angus cow. Anamnesis included a dystocia followed by a gradual (16 days) onset of anorexia and abdominal distension. Prominent findings on the physical examination were marked dehydration, symmetrical distension of
Urological laparoscopy has gained increasing acceptance recently. Alterations in renal water and electrolyte homeostasis by carbon dioxide peritoneal insufflation, retroperitoneal insufflation and abdominal wall lifting were measured in 30 well-hydrated pigs over a 2-h period. Oliguria was observed
BACKGROUND
Perioperative serum potassium levels are closely associated with postoperative clinical outcomes after gastrointestinal surgery. The aim of our retrospective study was to identify the prevalence and risk factors for preoperative hypokalemia (before pneumoperitoneum) and to evaluate the
We measured plasma potassium concentrations in five anaesthetized pigs over a 3.5 h period during which a carbon dioxide pneumoperitoneum was maintained. During this period the abdominal pressure was kept at 1.96 kPa and normocapnia was maintained by intermittent positive pressure ventilation. The
Surgical treatment of adrenal disorders is increasingly performed under laparascopic approach. Both pneumoperitoneum and adrenal tumour manipulation may induce haemodynamic variations. The aim of this study was to compare the inhalational and intravenous anaesthetic management for laparascopic
Neuromuscular blocking agents (NMBAs) are commonly used in experimental laparoscopy in swine undergoing carbon dioxide pneumoperitoneum. Hypercapnia may be present and may prolong NMBAs' pharmacologic activity. The aim of this study is to evaluate the effect of permissive hypercapnia on the
