OBJECTIVES To test the effects of pressure-controlled (PCV) and volume-controlled (VCV) ventilation during one-lung ventilation (OLV) for thoracic surgery on right ventricular (RV) function. DESIGN A prospective, randomized, double-blind, controlled, crossover study. SETTING A single university hospital. PARTICIPANTS Fourteen pairs of consecutive(More)
BACKGROUND Protective mechanical ventilation strategies using low tidal volume or high levels of positive end-expiratory pressure (PEEP) improve outcomes for patients who have had surgery. The role of the driving pressure, which is the difference between the plateau pressure and the level of positive end-expiratory pressure is not known. We investigated the(More)
BACKGROUND Preoperative dexmedetomidine administration blunts haemodynamic and hormonal responses to tracheal intubation and reduces anaesthetic requirements. We hypothesized that dexmedetomidine would reduce the maternal haemodynamic and hormonal responses to elective caesarean delivery without harmful neonatal effects. METHODS After ethical approval, 68(More)
BACKGROUND The use of low tidal volume during one-lung ventilation (OLV) has been shown to attenuate the incidence of acute lung injury after thoracic surgery. OBJECTIVE To test the effect of tidal volume during OLV for video-assisted thoracoscopic surgery on the extravascular lung water content index (EVLWI). DESIGN A randomised, double-blind,(More)
BACKGROUND Ketorolac may attenuate the maternal stress response to tracheal intubation, while avoiding opioid-induced neonatal depression. We aimed to evaluate the haemodynamic and hormonal effects of prophylactic ketorolac on surgical stress and analgesia after caesarean delivery. METHODS After ethical approval, 90 patients scheduled for elective(More)
The prophylactic use of small doses of ephedrine may counter the hypotension response to propofol anesthesia with minimal hemodynamic changes. One hundred-fifty patients scheduled for valve surgery were randomly assigned into five groups (n = 30 for each) to receive saline, 0.07, 0.1, or 0.15 mg/kg of ephedrine, or phenylephrine 1.5 μg/kg before induction(More)
Intravenous infusion of lidocaine attenuates the stress response to surgery. We aimed to evaluate the effects of perioperative lidocaine on the hemodynamic and hormonal responses for cesarean delivery. After the gaining of ethical approval, 90 patients scheduled for elective cesarean delivery were randomly allocated to receive either lidocaine 1.5 mg·kg−1(More)
PURPOSE The main objective of this survey is to describe the current practice of thoracic anesthesia in the Middle Eastern (ME) region. METHODS A prospective online survey. An invitation to participate was e-mailed to all members of the ME thoracic-anaesthesia group. A total of 58 members participated in the survey from 19 institutions in the Middle East.(More)
OBJECTIVES The use of continuous ultrafiltration may be effective in preventing the hepatic decompensation in cirrhotic patients after valvular heart surgery with cardiopulmonary bypass (CPB). The authors aimed to evaluate the effects of continuous ultrafiltration on the need for blood transfusion, liver function tests, duration of postoperative ventilatory(More)
