Laparoscopic cholecystectomy is a gold standard surgical procedure for gallbladder operation. It causes altered haemodynamic responses due to pneumoperitoneum and surgical procedure also causes high incidence of postoperative nausea &vomiting. Clonidine has been shown to reduce intraoperative haemodynamic instability. This randomized prospective single blind clinical study was designed to evaluate the efficacy of oral clonidine premedication for attenuation of haemodynamic responses associated with pneumoperitoneum & also reduce the incidence of postoperative nausea & vomiting and carried out in the department of Anaesthesia Analgesia and Intensive care Medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2010 to June 2010...

Necrotizing enterocolitis (NEC) is a frequently encountered condition in the premature neonate, which can have devastating effects. The signs and symptoms of NEC are variable and can be confused with those of sepsis. An abdominal radiograph is often obtained for diagnosis, and findings that indicate NEC include pneumatosis and portal venous gas. The treatment of NEC includes gastrointestinal rest, gastric decompression, broad-spectrum intravenous antibiotics, and systemic support. A finding of pneumoperitoneum signifies intestinal perforation, which requires surgical intervention...

BACKGROUND: Pneumatosis cystoides intestinalis (PCI) is a rare self-limiting condition characterized by air-filled cysts within intestinal walls. Diagnosis should be prudent because it can mimic pneumoperitoneum leading to unnecessary treatment such as surgical exploration. Although various drugs including anti-neoplastic agents have been suggested as etiologies, cases related to sunitinib are sparse. Because of the rarity of this unusual side effect by sunitinib, we report the case report...

INTRODUCTION: Laparoscopic cholecystectomy (LC) is usually performed under general anesthesia. Recently, laparoscopic cholecystectomy under regional anesthesia has become popular, but this creates a serious risk of thromboembolism because of pneumoperitoneum, anesthesia technique, operative positioning, and patient-specific risk factors. AIM: This randomized controlled trial compares the effects of two different anesthesia techniques in laparoscopic cholecystectomy on coagulation and fibrinolysis...

Pheochromocytoma is a catecholamine-producing tumour and laparoscopic adrenalectomy is its treatment of choice. During pneumoperitoneum insufflation and tumour handling there is a high risk of massive catecholamine release and hypertensive crisis. After tumour excision, severe arterial hypotension is a common effect, due to relative vasodilation and the residual effect of antihypertensive drugs. We report the case of a patient with pheochromocytoma who was treated with laparoscopic adrenalectomy. During surgical manipulation there was a sudden hypertensive peak that could be controlled quickly with clevidipine infusion...
