The effect of intraoperative lung protective ventilation vs conventional ventilation, on postoperative pulmonary complications after cardiopulmonary bypass.

This study aimed to evaluate the effects of high positive-end expiratory pressure (PEEP) and low tidal volume (TV) and recruitment maneuver, on postoperative pulmonary complications (PPCs) after coronary artery bypass grafting (CABG) surgery. This study is a randomized double blind clinical trial on 64 patients who were undergoing CABG surgery, and were randomly divided into two groups of conventional ventilation (C-Vent) with TV of 9 mL/kg and PEEP=0 cm H2O, and lung protective ventilation (P-Vent), with 6 mL/kg TV and PEEP=10 cm H2O with recruitment maneuver every 30 minutes. Measures of PPCs and modified clinical pulmonary infection score (mCPIS), were assessed for the first 24 hours of postoperative time in order to evaluate the pulmonary complications.

Comparing the Effect of Preoperative Administration of Melatonin and on Postoperative Cognitive Disorders in Adult Patients Undergoing Elective Surgery.

Background: Anxiety is a preoperative complication, which most patients encounter. The use of a premedication to reduce preoperative anxiety with minimal cognitive impairment is crucial.

Objectives: This study was conducted to compare the sedative effect of preoperative melatonin and in patients undergoing elective surgery regarding their potential for postoperative cognitive disorders.

Remifentanil infusion during emergence moderates hemodynamic and cough responses to the tracheal tube: A randomized controlled trial.

Objective: To examine the severity of cough and straining at the time of emergence from anesthesia.

Design: Double-blind randomized, placebo-controlled study.

Setting: University-affiliated hospital.

Anesthetic management for lower limb fracture in severe aortic valve stenosis and fat embolism: a case report and review of literature.

Introduction: Anesthesia in severe aortic stenosis, which describes a valve surface area less than 1 cm(2), can result in rapid clinical deterioration and patient mortality. These patients may require treatment for aortic stenosis before any surgical intervention. In suitable patients percutaneous balloon aortic valvutomy appears to carry lower risk, but in emergency situations, it is important to determine which kind of anesthesia technique has the lowest risk for these patients, without any cardiac intervention.

Analgesic effects of paracetamol and morphine after elective laparotomy surgeries.

Background: Opioids have been traditionally used for postoperative pain control, but they have some unpleasant side effects such as respiratory depression or nausea. Some other analgesic drugs like non-steroidal anti-inflammatory drugs (NSAIDs) are also being used for pain management due to their fewer side effects.

Objectives: The aim of our study was to compare the analgesic effects of paracetamol, an intravenous non-opioid analgesic and morphine infusion after elective laparotomy surgeries.
