Randomized Controlled Trial Comparative StudyChloroprocaine 40 mg produces shorter spinal block than articaine 40 mg in day-case knee arthroscopy patients.
Articaine and chloroprocaine have recently gained interest as short-acting spinal anaesthetics. Based on previous work comparing articaine 60 mg with chloroprocaine 40 mg, we hypothesised that articaine 40 mg and chloroprocaine 40 mg would produce similar spinal anaesthesa regarding block onset, maximal spread, and recovery. ⋯ Both A40 and C40 provided mainly adequate spinal anaesthesia for day-case knee arthroscopy. While onset and maximal spread were comparable, the recovery from motor block was clearly faster with chloroprocaine after equivalent doses of spinal articaine and chloroprocaine.

Randomized Controlled Trial Comparative StudySevoflurane has no adverse effects on renal function in cirrhotic patients: a comparison with propofol.
Cirrhotic patients are prone to developing renal dysfunction after anaesthesia and surgery. However, no consensus has been reached whether sevoflurane could have adverse effects on renal function in cirrhotic patients. We hypothesised that the use of sevoflurane for general anaesthesia would lead to post-operative renal dysfunction in cirrhotic patients undergoing liver resection. ⋯ Sevoflurane does not seem to impair post-operative renal function in cirrhotic patients undergoing liver resection.

Randomized Controlled TrialAssessment of intraoperative microaspiration: does a modified cuff shape improve sealing?
Intra-operative aspiration of oropharyngeal secretions is associated with post-operative pneumonia. The use of endotracheal tubes (ETTs) with a modified cuff shape could be one preventive action. In this clinical, prospective, randomised controlled trial, we hypothesised that altering the cuff shape to a tapered shape could reduce the aspiration incidence. The primary outcome was aspiration of dye solution into the trachea. ⋯ Short-term use of tapered-shaped polyvinylchloride cuffs in surgical patients results in more effective sealing of the tracheal lumen in comparison with a traditional barrel-shaped polyvinylchloride cuffs. Further evaluation is needed to determine whether a reduction in post-operative pneumonia can be demonstrated when these cuffs are used.

Randomized Controlled Trial Comparative StudyThe disposable Ambu aScope vs. a conventional flexible videoscope for awake intubation -- a randomised study.
A new disposable flexible videoscope, the Ambu® aScope, has several potential advantages compared with reusable devices, but it is a prerequisite for its widespread use that it functions sufficiently well in the management of patients in whom difficulty with airway management is anticipated and awake intubation is indicated. ⋯ Both the disposable aScope and the reusable Olympus videoscope allowed safe awake intubation in our elective patients with severely difficult, but uncompromised, airways. The occasional need to employ a spare scope because of malfunctioning would make the disposable aScope less suitable in patients with acutely compromised airways.
