Randomized Controlled Trial
The effects of magnesium sulphate on sevoflurane minimum alveolar concentrations and haemodynamic responses.
Magnesium administered before anaesthesia induction results in a significant reduction in intravenous anaesthetic consumption. The purpose of this study was to evaluate whether the dose of intravenous magnesium sulphate reduces the minimum alveolar anaesthetic concentration of sevoflurane for endotracheal intubation (MACEI) and skin incision (MAC), and attenuates haemodynamic responses. ⋯ Magnesium sulphate administered before induction of anaesthesia increases MAC of sevoflurane and reduces cardiovascular responses to intubation.

Randomized Controlled Trial Comparative Study
Low flow desflurane and sevoflurane anaesthesia in children.
Low flow desflurane and sevoflurane anaesthesia were administered to children and compared for haemodynamic response, renal and hepatic function, recovery time and postoperative nausea and vomiting. ⋯ Low flow desflurane and sevoflurane anaesthesia do not adversely affect haemodynamic parameters, hepatic and renal function in children. Desflurane may be preferred when early recovery from anaesthesia is warranted.

Randomized Controlled Trial Comparative Study
Comparison of the modified Airway Management Device with the Proseal laryngeal mask airway in patients undergoing gynaecological procedures.
The modified Airway Management Device (AMD) and the Proseal laryngeal mask airway (PLMA) are both supraglottic airway devices designed to maintain airway patency and allow ventilation during anaesthesia. In this prospective, randomized trial, we compared the two devices in patients undergoing major gynaecological procedures. ⋯ The modified AMD has a significant lower first time successful placement rate, required a longer insertion time and has a lower oropharyngeal leak pressure than the PLMA. It also demonstrated an increased loss of airway during anaesthesia. The modified AMD needs further evaluation on its efficacy and safety before its further use can be recommended.

We decided to investigate the pathogenesis of pulmonary ventilatory and radiographic abnormalities in patients after major vascular surgery. ⋯ Our data suggest that mild, subclinical, pulmonary oedema is relatively common after major vascular surgery, mainly caused by increased pulmonary capillary permeability in the absence of overt heart failure. However, permeability oedema only partially contributes to postoperative lung injury score and need for mechanical ventilation, suggesting a major contribution by atelectasis.

We tested the feasibility of using the intubating laryngeal mask airway Fastrach (ILMA) as a ventilatory device and for flexible lightwand-guided tracheal intubation for out-of-hospital cardiopulmonary resuscitation by an emergency physician. ⋯ The intubating laryngeal mask airway has a high success rate as a ventilatory device and as a flexible lightwand-guided airway intubator during out-of-hospital cardiopulmonary resuscitation by a well-trained emergency physician. This technique may be particularly useful when there is limited access to the head and neck.
