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.

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.

Comparative StudyA comparison of electronic and handwritten anaesthetic records for completeness of information.
Complete documentation in anaesthetic records is important for patient management, research and quality assurance and has medicolegal implications. This study compares the completeness of information contained in electronic versus handwritten intraoperative anaesthetic records. A sample of 70 handwritten records was randomly selected from anaesthesia performed in the month prior to implementation of the Integrated Injectable Drug Administration and Automated Anaesthesia Record System and compared to a similar sample of electronic records generated eight months later. ⋯ There was no overall difference in the completeness of electronic versus handwritten records. Several differences did exist however, highlighting both clinically important advantages and deficiencies in the electronic system. Records from both systems sometimes lacked important information.

Vocal cords-carina distance in anaesthetised Caucasian adults and its clinical implications for tracheal intubation.
Previous work has assessed vocal cords-carina distance in Chinese patients and compared it to commonly used tracheal tubes. In addition, an attempt was made to identify surface anatomy measurements with short tracheas. We have examined the length of tracheas in Caucasian patients and compared it with currently used tracheal tubes. ⋯ The best predictors in our study of vocal cords-carina distance less than 11.3 cm were a height of < or = 182 cm, an ulnar length of < or = 31.2 cm or a thyroid to xiphisternum distance of < or = 31.8 cm. This correlation is poor however and prediction of vocal cords-carina distance remains difficult clinically. It was therefore concluded that surface anatomy measurements are a poor predictor of vocal cords-carina distance.
