background: this study was designed to investigate the effect of intravenous magnesium sulfate on hemodynamic changes induced by pneumoperitoneum in patients undergoing laparoscopic cholecystectomy. methods: a randomized, placebo controlled study was performed on 52 asa class i or ii aged 20-70 years patients undergoing laparoscopic cholecystectomy with pneumoperitoneum with carbon dioxide. bef...

conclusions we conclude that volume of residual pneumoperitoneum is a contributing factor in the etiology of postoperative pain after laparoscopic cholecystectomy. results at the end of the study, 17 patients (30.9%) had no residual pneumoperitoneum after 24 hours; which 23 (41.81%) had mild residual pneumoperitoneum, eight (14.54%) had moderate pneumoperitoneum and seven (12.72%) had severe pn...

Pneumoperitoneum frequently indicates a perforated abdominal viscus that requires emergent surgical management. However; pneumoperitoneum, on rare occasion, can occur without perforation. In these cases, it is defined as benign pneumoperitoneum. Benign pneumoperitoneum means asymptomatic free intra-abdominal air or pneumoperitoneum without peritonitis and can occur occasionally with colonoscopy...

BACKGROUND Gasretention in the peritoneal cavity plays an important role in inducing postoperative pain after laparoscopy, which is inevitably retained in the peritoneal cavity. OBJECTIVES The aim of this study was to detect the relation between the volume of residual gas and severity of shoulder and abdominal pain. PATIENTS AND METHODS In this Prospective study 55 women who were referred f...

Pneumoperitoneum, free intra-abdominal air, usually results from the perforation of a hollow viscous. In approximately 10% of cases, however, pneumoperitoneum is not caused by gastrointestinal perforation. These cases of "spontaneous pneumoperitoneum" generally follow more benign course and may not require surgical intervention. Examples include cardiopulmonary resuscitation (CPR), malrotation,...

Figure 1 – Chest X-ray shows pneumoperitoneum in the right and left subdiaphragmatic region. Figure 2 – Chest X-ray shows pneumoperitoneum in the right and left subdiaphragmatic region. INTRODUCTION Pneumoperitoneum is caused by perforation of hollow viscera, with perforated peptic ulcer occurring more frequently. In rare cases, pneumoperitoneum is not caused by visceral perforation, the cause ...

BACKGROUND Disadvantages related to CO2 pneumoperitoneum have led to development of the abdominal wall retractor (AWR), a device designed to facilitate laparoscopic surgery without conventional pneumoperitoneum (15 mmHg CO2). We investigated the effects of the AWR on hemodynamics and gas exchange in humans. We also investigated whether the use of an AWR imposed extra technical difficulties for ...

BACKGROUND The advent of laparoscopic surgery has benefited the patient and surgeon; however creation of pneumoperitoneum for same has bearings during the perioperative period. These effects of pneumoperitoneum are associated with significant haemodynamic changes, increasing the morbidity of the patient. AIM The present study compared the efficacy of dexmedetomidine and esmolol on hemodynamic...

BACKGROUND AND OBJECTIVES 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 dogs anesthetized with sodium thiopental and fentanyl, which were divided in t...

BACKGROUND/AIMS Pneumoperitoneum is recognized as a benign and self-limiting finding after the insertion of a percutaneous endoscopic gastrostomy (PEG) tube, while complicated pneumoperitoneum is rarely reported. The aim of this study was to reappraise pneumoperitoneum following PEG. METHODS We retrospectively reviewed 193 patients who underwent PEG from May 2008 to May 2014. All patients had...
