Randomized Controlled Trial Comparative Study Clinical TrialClinical evaluation of low-flow sevoflurane anaesthesia for paediatric patients.
Sevoflurane expenditure, inspired gas humidity, temperature, soda lime temperature, and compounds A and B were measured during high and low fresh gas flow anaesthesia in paediatric patients. ⋯ In conclusion, sevoflurane used for paediatric patients in a circle system with a fresh gas flow of 0.6l.min-1 resulted in a significantly reduced sevoflurane expenditure, higher inspired absolute humidity, but not temperature, compared to a fresh gas flow of 6l.min-1. Low levels of compounds A and B were detected.

Case ReportsAirway obstruction due to arytenoid prolapse in a child.
In paediatric patients, obstruction of the upper airway is still a common problem during general anaesthesia. This case report documents the susceptibility of arytenoids to prolapse in paediatric patients during halothane anaesthesia. The use of video endoscopy provides an excellent tool for visualizing this type of airway obstruction; and continuous positive airway pressure is an effective treatment for clearing the airway.

Comparative StudyEffect of experience with spinal anaesthesia on the development of post-dural puncture complications.
This clinical study was conducted in order to investigate the effect of operator experience with spinal anaesthesia (SA) on development of postural post-dural puncture headache (PPDPH) and postoperative backache. ⋯ We could not demonstrate an effect of experience and training on development of complications after SA with regard to PPDPH and backache.

Comparative StudyClinical application of diadenosine tetraphosphate (Ap4A:F-1500) for controlled hypotension.
In our animal study, it was revealed that diadenosine tetraphosphate (Ap4A:F-1500) has a dose-dependent hypotension effect of up to 60% decrease in mean arterial pressure compared to control value. Furthermore, in healthy male volunteers, the safety of Ap4A up to 4 mg.min-1 was confirmed. In patients who require surgical procedures under general anesthesia together with controlled hypotension, hypotension was induced by Ap4A in order to examine its hypotensive effect and modulating action on the blood pressure. ⋯ As it produces an excellent hypotensive effect together with a modulating action on blood pressure, Ap4A was assessed as useful in producing controlled hypotension.

Comparative StudyIntact proprioception and control of labour pain during epidural analgesia.
Accurate proprioception is critical while walking, yet an ambulatory epidural regimen that provides adequate analgesia for labour while simultaneously preserving proprioceptive input has not been described. ⋯ This study confirms that the addition of lumbar epidural fentanyl 100 micrograms to 15 mg of epidural bupivacaine provides good control of labour pain with no motor block and establishes that this combination preserves dorsal column sensory function.
