Changes in calculated arterio-jugular venous glutamate difference and SjvO2 in patients with severe traumatic brain injury.
Cerebral metabolic impairment is feared to induce secondary brain damage following traumatic brain injury (TBI). The present study was designed to assess the temporal profile of calculated arterio- jugular venous differences in glutamate (AJVDglu) and SjvO(2) in patients subjected to continuous pharmacologic coma. Metabolic impairment was assumed to be reflected by increased jugular venous glutamate levels and decreased jugular venous oxygen saturation (SjvO(2)). ⋯ During pharmacologic coma increased ICP was associated with significantly decreased SjvO(2) which coincided only with a trend to increased cerebral glutamate release. Calculated AJVDglu appears to be inferior in unmasking altered brain metabolism compared to SjvO(2) whenever ICP is increased.

Systemic adverse events during 2005 phacoemulsifications under monitored anesthesia care: a prospective evaluation.
The aim of the study was to evaluate the systemic adverse events triggering on-call anesthesiologist's intervention during 2005 phacoemulsification under topical anesthesia on a day-surgery monitored anesthesia care regimen. ⋯ One-day cataract surgery performed under topical anesthesia with monitored anesthesia care required anesthesiologist intervention in 21.6% of cases, mainly because of agitation or hypertension. Agitation occurred more often in younger patients with neurological or psychiatric comorbidities. Hypertension occurred more often in older patients with higher ASA scores.

ReviewWhen, where and how to initiate hypothermia after adult cardiac arrest.
Therapeutich hypothermia (TH) has been shown to improve neurological outcome and survival after witnessed cardiac arrest (CA) that is due to ventricular fibrillation. Although TH is widely used following witnessed CA as well as all forms of initial rhythm, the mortality rate after CA remains unacceptably high, and additional study is needed to understand when and how to implement hypothermia in the post-resuscitation phase. ⋯ Thus, hypothermia use should not be limited to the Intensive Care Unit but can be initiated in the field/ambulance or in the Emergency Department, then continued after hospital admission- even during specific procedures such as coronary angiography-as part of the global management of CA patients. Various methods (both non-invasive and invasive) are available to achieve and maintain the target temperature; however, only some of these methods-which include cold fluids, ice packs, iced pads and helmet and trans-nasal cooling- are easily deployed in the pre-hospital setting.
