The feasibility of monitoring measured intravascular volumes and the cardiac filling pressures were compared to reflect the optimal volume status of postoperative patients. ⋯ Intrathoracic blood volume reflects more accurately the preload dependency of cardiac output in postoperative patients than left/right-sided cardiac filling pressures.

Drug mixtures containing sufentanil may be unstable owing to absorption into the drug reservoirs of patient-controlled epidural analgesia systems that contain polyvinylchloride. The stability of sufentanil in a mixture of ropivacaine 0.2% in a 750 mL reservoir was therefore investigated. ⋯ Sufentanil citrate at 0.5-1.0 microg mL(-1) in an admixture of ropivacaine 0.29 for 5 days, which is the usual period for postoperative epidural analgesia, remains stable in a polyvinylchloride reservoir. There is no change in the drug concentration even if the reservoir is stored for 4 weeks at 8 degrees C.

Letter Case Reports
Use of the intubating laryngeal mask airway in a case of ankylosing spondylitis for coronary artery bypass grafting.
The intubating laryngeal mask airway is a modification of the conventional laryngeal mask and is used as a tool for difficult intubation. It can be inserted without placing the head and neck in the Magill position and has been used successfully in cervical spine injuries. Reported is a case of successful insertion of the intubating laryngeal mask and subsequent intubation through it in a patient with ankylosing spondylitis with cervical involvement resulting in a fixed flexion deformity who underwent coronary artery bypass grafting.

Randomized Controlled Trial Comparative Study Clinical Trial
Iontophoretically applied lidocaine and the prevention of pain associated with the injection of intravenous propofol: a comparison with intravenous lidocaine.
Pain following the injection of propofol is a common problem. It is often treated by the coadministration of intravenous lidocaine. Iontophoresis, which facilitates the delivery of charged molecules such as lidocaine to body tissues, may be a practical alternative to lessen the pain. ⋯ The iontophoretic administration of lidocaine 60 mg does not compare favourably with lidocaine 40 mg mixed with propofol for the reduction of pain on administration of propofol.

Randomized Controlled Trial Comparative Study Clinical Trial
Cuffed oropharyngeal airway as a suitable alternative to the laryngeal mask airway for minor outpatient surgery.
To compare the application of the cuffed oropharyngeal airway and the laryngeal mask airway on anaesthetized adult patients undergoing minor outpatient surgery. ⋯ The results suggest that the cuffed oropharyngeal airway was an effective alternative airway in spontaneously breathing patients during short procedures.
