The use of ProSeal laryngeal mask airway in caesarean section--experience in 3000 cases.
In this single biggest study to date of 3,000 women undergoing elective Caesarean section under general anaesthesia with the LMA ® ProSeal™, there was only one case of regurgitation, and no aspiration.

Randomized Controlled Trial Comparative StudyA comparison of low dose hyperbaric levobupivacaine and hypobaric levobupivacaine in unilateral spinal anaesthesia.
The aim of this study was to compare the clinical effects and characteristics of hyperbaric and hypobaric levobupivacaine for unilateral spinal anaesthesia. Sixty patients were randomly allocated into two groups to receive either 7.5 mg (1.5 ml) hyperbaric levobupivacaine 0.5% or 7.5 mg (4 ml) hypobaric levobupivacaine 0.1875% for elective arthroscopic surgery of the knee under spinal anaesthesia. The level and duration of sensory block, intensity and duration of motor block were recorded. ⋯ In the hyperbaric group, the motor block scores were higher on the operative side during first 10 minutes than they were in the hypobaric group (P < 0.002). Motor block regression was faster in the hyperbaric group (P = 0.01). Hyperbaric and hypobaric levobupivacaine both provided satisfactory unilateral spinal anaesthesia with good haemodynamic stability for arthroscopic surgery, but with more frequent unilateral spinal anaesthesia in the hyperbaric group.

Can learning to sustain life be BASIC? Teaching for the initial management of the critically ill in Australia and New Zealand.
Commonly in Australia and New Zealand, initial intensive care support of critically ill patients is by non-intensive care trained medical and nursing staff Basic Assessment and Support in Intensive Care (BASIC) is an internationally run short course to assist practitioners to gain knowledge and skills to manage the early hours of critical illness. The aim of this study was to assess the performance and acceptance of the BASIC course as conducted in an Australian metropolitan teaching hospital and a major regional centre in New Zealand. Performance on pre- and post-course multiple choice examinations and the overall course assessment by all participants attending between 2005 and 2009 was analysed. ⋯ The post-course examination score was predicted by pre-course examination score (beta = 0.22, 95% confidence interval 0.17 to 0.27), nursing occupation, (beta = -3.96, 95% confidence interval -5.03 to -2.90) and the availability of a scenario-based simulation module (beta = 0.22, 95% confidence interval 0.17 to 0.27, R2 = 0.38, P < 0.001). Participants generally found they had learned a great deal from the program and that the course material was of an appropriate level. The BASIC course was found to be a positive learning experience for health care practitioners inexperienced in the management of the critically ill.

Case ReportsUltrasound-guided axillary plexus block in a child with dystrophic epidermolysis bullosa.
We report the use of ultrasound-guided axillary brachial plexus block in a child with dystrophic epidermolysis bullosa needing surgical treatment of the right hand. The regional anaesthesia was used in association with sedation/ anaesthesia. This technique is suitable for these difficult patients because it can minimise the risk of new bullae formation due to palpation of landmarks or unintentional intra- or subcutaneous injections. ⋯ This management plan provided good surgical conditions, early postoperative analgesia, minimised stress for the patient and avoided the need to manipulate the airway with instruments and the associated risk of mucosal bullae. The classification and breadth of clinical manifestation of epidermolysis bullosa is complex and briefly summarised. The anaesthetist should clarify the details of a particular patient's form of epidermolysis bullosa, especially in terms of mucosal involvement, as this may greatly influence planning for a procedure.

Loss of resistance to saline reduces responses accompanying spinal needle insertion during institution of 'needle-through-needle' combined spinal-epidural analgesia.
Normal saline or air is used to identify loss of resistance during identification of the epidural space for combined spinal-epidural analgesia. Following epidural needle placement using air for loss of resistance, up to 80% of parturients move, grimace, vocalise or experience paraesthesia or dysaesthesia during subsequent dural puncture by a spinal needle. We compared the effects of saline versus air for loss of resistance on the occurrence of these subjective and objective responses during thecal penetration. ⋯ In those given saline and air respectively, 5 (18%) and 12 (44%) parturients responded to and/or acknowledged having perceived dural puncture (P < 0.005). Overall, 7 and 31 (P < 0.0005) subjective and objective responses occurred during dural puncture in those given saline and air, respectively. The study found that use of saline to determine loss of resistance is associated with fewer patient responses at the moment of thecal penetration during 'needle-through-needle' placement of the spinal needle at combined spinal-epidural analgesia.
