Randomized Controlled TrialThe effects of propofol or sevoflurane on free radical production after tourniquet induced ischaemia-reperfusion injury during knee arthroplasty.
We studied the effects of anesthesia with propofol or sevoflurane on the production of free oxygen radicals during total knee arthroplasty performed with the use of an ischemic tourniquet by measuring the levels of malondialdehyde (MDA). ⋯ Propofol may have anti-oxidant properties in orthopaedic surgery requiring tourniquet application, but sevoflurane needs further study.

Comparative StudyMorphine versus morphine-ketamine association in the management of post operative pain in thoracic surgery.
The aim of this study was to assess the quality of postoperative analgesia obtained with morphine-ketamine association administered in self-pain controlled analgesia, as well as the amount of morphine that has been spared. Patients who had to undergo thoracic surgery were selected. They were divided into two groups: G1 was made up of patients receiving 0.5 mg/ml of morphine associated with a placebo, with boluses of 2 ml and refractory periods of 5 minutes ; and G2 made up of patients receiving 0.5 mg/ml of ketamine associated with 0.5 mg/ml of morphine with same boluses and refractory periods. ⋯ The assessment showed that the response to pain at rest was the same in the two groups as from the twelfth hour. On stimulation, the analgesic response was better in G2 as well as the amount of morphine spared. This study shows that the administration of ketamine in association with morphine in the post operative period procures a favourable efficiency-tolerance relationship and provides a good means of sparing morphine.

Case ReportsMyasthenia gravis and thymectomy: an anaesthetic approach.
In this paper, we discuss the case of a 48 year old patient with newly diagnosed myasthenia gravis, who is scheduled for a thymectomy. The patient's history showed an undocumented difficult intubation, which led to the approach of an awake intubation after sevoflurane induction. We used a slightly modified non-muscle relaxant technique, allowing induction and maintanance of anesthesia under safe and excellent conditions.

Maintaining normothermia during off-pump coronary artery bypass (OPCAB) surgery is difficult. The purpose of the present study is to determine the effect of the Inditherm Patient Warming System (IPWS) with standard institutional care during OPCAB surgery. ⋯ The combination of the IPWS with standard thermal care provides higher core temperatures during OPCAB surgery.

Case ReportsVideo-assisted laryngoscopy: a useful adjunct in endotracheal intubation.
The difficult airway is the single most important cause of anaesthesia-related morbidity and mortality and most catastrophes are due to unexpected difficulty, which are more likely in emergencies. We report a difficult airway scenario in a patient with a high energetic trauma and used several techniques for the "can't intubate, can't ventilate scenario". Eventually, successful intubation was obtained with the video-assisted laryngoscope.
