Data linkage enables evaluation of long-term survival after intensive care.
Outcomes of intensive care are important to the patient and for assessment of benefit. Short-term outcomes after critical illness are well described, but less is known about long-term outcomes. This study describes the use of data linkage, combining intensive care unit (ICU) clinical data with administrative morbidity and mortality data, to assess long-term outcomes after treatment in ICU. ⋯ Age, type of admission, severity of illness (measured by Acute Physiologic and Chronic Health Evaluation (APACHE) II and the presence of organ failure), ICU length of stay, comorbidity (Chronic Health Evaluation and Charlson comorbidity index) and ICU admission diagnosis, were all associated with survival at 1, 3, 5, 10, and 15 year follow-up (P<0.001 at all time points). Linkage of clinical and administrative data provides a feasible method for ascertaining long-term survival after critical illness. Age, admission severity of illness, diagnosis and comorbidity influenced long-term unadjusted survival.

Case ReportsAnaesthetic management of a patient with relapsing polychondritis undergoing laparoscopic surgery.
We describe the anaesthetic management of a patient with relapsing polychondritis who underwent laparoscopic cholecystectomy. We failed to secure a patent airway with a ProSeal laryngeal mask airway, probably because of the deformity of the larynx. ⋯ Positive pressure ventilation with 5 cm H2O positive end-expiratory pressure and surgery were safely performed. In relapsing polychondritis, recurrent inflammation and destruction of laryngeal and tracheobronchial cartilage causes airway obstruction, and various sizes of tracheal tubes and other airway manipulation devices should be prepared.

Case ReportsCricothyroidotomy: a short-term measure for elective ventilation in a patient with challenging neck anatomy.
Cricothyroidotomy is a well established technique of airway management in emergency situations where translaryngeal intubation cannot be achieved. This case report describes a case where cricothyroidotomy was used for elective ventilation for short period of 48 hours in a patient who had a vocal cord palsy, supraglottic oedema and inflammation. Surgical tracheostomy was considered the preferred option, but this was deemed impossible due to the challenging neck anatomy in this case.

Biography Historical ArticleBrian Dwyer and the St. Vincent's Pain Clinic 1962 to 1989.
Brian Dwyer was the Director of the Department of Anaesthetics at St. Vincent's Hospital in Sydney from 1955 to 1985. He developed a major interest in the management of intractable pain and was most impressed by the multidisciplinary pain clinic which was commissioned at the University of Washington in Seattle by John Bonica in 1960. ⋯ As a result of his work, Brian Dwyer received international recognition as a pioneer in the field of chronic pain management and the St. Vincent's Pain Clinic served as a model for the establishment of similar units, both in Australia and overseas. Brian Dwyer was the first chairman of the Clinic and remained in that position until his retirement in 1989.

Protein contamination of the Laryngeal Mask Airway and its relationship to re-use.
The Laryngeal Mask Airway is a reusable device for maintaining the patency of a patient's airway during general anaesthesia. The device can be reused after it has been cleaned and sterilized. Protein contamination of medical instruments is a concern and has been found to occur despite standard sterilization techniques. ⋯ Linear regression analysis of the degrees of staining of the airway revealed that protein contamination occurs after the first use of the device and this increases with each subsequent use. This finding highlights the concern that the currently used cleaning and sterilization methods do not prevent the accumulation of proteinaceous material on Laryngeal Mask Airways. Consideration should be given to the search for more efficient cleaning and sterilization techniques or the use of disposable devices.
