Granisetron versus dexamethasone in prophylaxis of nausea and vomiting after laparoscopic cholecystectomy.

Background: Post-operative nausea and vomiting (PONV) is one of the common problems after laparoscopic cholecystectomy.

Objectives: The current study aimed to compare Dexamethasone effect with that of Granisetron in prevention of PONV.

Patients And Methods: In the current study 104 patients aged 20-60 with ASA class I or II who were candidates for laparoscopic cholecystectomy were included in the study.

Volume threshold for chest tube removal: a randomized controlled trial.

Background: Despite importance of chest tube insertion in chest trauma, there is no general agreement on the level of daily volume drainage from chest tube. This study was conducted to compare the effectiveness and safety of chest tube removal at the levels of 150 ml/day and 200 ml/day.

Methods: Eligible patients (138) who needed replacement of chest tube (because of trauma or malignancy) were randomized into two groups; control (removal of chest tube when drainage reached to 150 ml/day) and trial (removal of chest tube at the level of 200 ml/day).
