Accuracy of recorded body temperature of critically ill patients related to measurement site: a prospective observational study.
Accurate measurement of body temperature is an important indicator of the status of critically ill patients and is therefore essential. While axillary temperature is not considered accurate, it is still the conventional method of measurement in Asian intensive care units. There is uncertainty about the accuracy of thermometers for the critically ill. ⋯ When blood temperature data was available, the mean difference between blood and bladder temperature readings was small (0.02±0.21°C). Compared with bladder temperature, mean difference for axillary temperature was -0.33±0.55°C and for tympanic temperature it was -0.51±1.02°C. For critically ill patients, recorded axillary temperature was closer to bladder temperature than tympanic temperature.

Predictors of severity in deep neck infections admitted to the intensive care unit.
A retrospective study was performed on adult patients admitted for surgical drainage of deep neck infections and admitted to the intensive care unit (ICU) during a period of 52 months. Severe infection was defined as septic shock/severe sepsis, mediastinitis, empyema or necrotising fasciitis. Complicated course was defined as ICU stay >8 days, reintubation, tracheostomy, renal replacement therapy, critical illness, myopathy or mortality. ⋯ Serious complications occur frequently in patients with deep neck infections surgically drained and admitted to the ICU. Higher severity scores are associated with both severe infection and a complicated course. Retropharyngeal and parapharyngeal locations are associated with severe infection and a complicated course respectively.

Therapeutic hypothermia following out-of-hospital cardiac arrest (OHCA): an audit of compliance at a large Australian hospital.
Therapeutic hypothermia (TH) is now largely considered the standard of care for patients following out-of-hospital cardiac arrest caused by ventricular arrhythmias, although the effective implementation of TH for individual patients can be challenging. This study aimed to document the effectiveness of TH when it is used at the discretion of treating physicians and not under the auspices of a research trial or protocol. A retrospective review of intensive care unit admissions over a four-year period detected 43 patients appropriate for TH. ⋯ Nineteen patients (44%) had a positive neurological outcome while 24 patients (56%) either died or had a poor neurological outcome. Without the control of a hospital protocol it was apparent that the implementation of TH in patients with an out-of-hospital cardiac arrest in our institution was inadequate. We recommend that TH is undertaken within the framework of a protocol that encompasses all the relevant departments.

A novel multimedia workshop on portable cardiac critical care ultrasonography: a practical option for the busy intensivist.
We aimed to assess the role of a short duration multimedia workshop to improve the knowledge and skills in cardiac critical care ultrasonography. Thirty critical care physicians participated in the cardiac critical care ultrasonography workshop. Two weeks prior to hands-on training, a three-hour web-based didactic lecture was provided to learners. ⋯ A short duration multimedia, hands-on workshop improved intensivists' knowledge, skills and confidence levels on cardiac critical care ultrasonography image acquisition. Further studies are needed to assess the sustainability of observed improvements. This module may be a practical option for the acquisition and maintenance of cardiac critical care ultrasonography knowledge and skills.
