Anaesthesia and intensive care
-
Critically ill patients are often unable to make decisions about life-sustaining treatments and surrogate decision-makers are relied upon. However, it is unclear how accurately the surrogates' decisions reflect patients' intentions and expectations. We interviewed 36 pairs of patients and their appointed surrogate decision-makers about their decisions regarding nine treatments in each of three scenarios. ⋯ The significantly higher surrogate scores suggest that the surrogates' decisions would have resulted in the patients having far more treatment than the patients would have wanted. In our participants, there was poor agreement between the decisions made by surrogates and patients. Further study is needed on measures such as facilitated discussions, advance directives and the difficulties that surrogates face, in order to improve the accuracy of surrogates' decisions and respect of patients' autonomy.

Case ReportsAscites misdiagnosed as a left pleural effusion during cardiac surgery: case report and suggested echocardiographic features to differentiate these entities.
The spleen and ascitic fluid are rarely imaged by transoesophageal echocardiography. In this case perisplenic ascitic fluid was misdiagnosed as a left pleural effusion and led to unnecessary surgical opening of the left pleural space during aortic valve replacement. ⋯ Second, perisplenic ascitic fluid can be seen to communicate with a lateral space (unlike pleural fluid). Third, perisplenic ascitic fluid lies entirely lateral to the descending aorta (unlike pleural fluid).

Survival and quality of life after prolonged intensive care unit stay.
There are few data on long-term outcomes in mixed groups of intensive care unit (ICU) patients with prolonged stays. We evaluated the relationship between length of stay in the ICU and long-term outcome in all patients admitted to our 31-bed department of medico-surgical intensive care over a one-year period who stayed in the department for more than 10 days (n = 189, 7% of all ICU admissions). Mortality increased with length of stay from 1 to 10 days (1 day 5%, 5 days 15%, 9 days 24%, 10 days 33%) but remained stable at about 35% for longer ICU stays. ⋯ In conclusion, in ICU patients, mortality increases with length of stay up to 10 days. Patients staying in the ICU for more than 10 days have a relatively good long-term survival. Most survivors have an acceptable quality of life.

Anaesthesia for emergency caesarean section, 2000-2004, at the Royal Women's Hospital, Melbourne.
The provision of anaesthesia for emergency caesarean section is a major part of the workload of obstetric anaesthetists and the urgency often dictates the mode of anaesthesia that can be provided. We have audited the provision of anaesthesia for 'immediate' caesarean sections over a four-year period following the introduction of a 'Code Green' system to coordinate a rapid response to an obstetric decision to proceed with an 'immediate' caesarean section. The records of all patients for whom a Code Green was called between July 2000 and June 2004 were studied. ⋯ General anaesthesia was most used between the hours of 0700 and 1700 h. A swift response to the call for an immediate caesarean section can be achieved when suitable facilities and procedures are in place. Administering an epidural bolus into an already established epidural catheter that is working effectively can allow a decision-to-delivery interval almost as short as general anaesthesia.

Case ReportsTranstracheal lignocaine: effective treatment for postextubation stridor.
Three cases of post-extubation stridor due to suspected laryngospasm are described in which a small dose of lignocaine injected intra-tracheally, through the cricothyroid membrane, produced rapid and effective relief of stridor with no early recurrence or side-effects. The procedure was performed safely and quickly and was well tolerated by patients. Trans-tracheal injection of local anaesthetic should be considered for treatment of post-extubation stridor in adults, so long as there is no risk of pulmonary aspiration, and pathological causes of laryngospasm have been excluded.
