Findings of the neuromuscular blocking agent rocuronium in blood from deceased subjects several months after exposure: A report of two cases.

Rocuronium is a neuromuscular blocking agent mainly used in anesthetic procedures. Two patients who died 53 and 76 days, respectively, after their last rocuronium exposure had low (0.002-0.007 mg/L) levels of the drug in femoral blood, urine and vitreous humor samples obtained at autopsy. In neither case, the cause of death was related to the exposure to rocuronium. Here, these two cases are presented and the implications of the findings discussed.

A man in his forties with impaired cognitive and circulatory function after a fall. / En mann i 40-årene med mental og sirkulatorisk påvirkning etter falltraume.

Falls can be dangerous, but sometimes whatever caused the fall can be even more dangerous. Here we present the case of a man who was hospitalised after a fall, but for whom identifying the cause and appropriate treatment took some time. A man in his forties was brought to the trauma unit of a university hospital. According to the information received by the Emergency Medical Communications Centre, he had fallen down a 3­4 m slope, possibly as a result of intoxication. The ambulance team reported both cognitive and circulatory impairment. There was no information to suggest previous illness or a history of substance abuse.

How do I get an emergency civilian walking blood bank running?

The shift toward using a transfusion strategy in a ratio to mimic whole blood (WB) functionality has revitalized WB as a viable option to replace severe blood loss in civilian health care. A military-civilian collaboration has contributed to the reintroduction of WB at Haukeland University Hospital in Bergen, Norway. WB has logistical and hemostatic advantages in both the pre- and in-hospital settings where the goal is a perfectly timed balanced transfusion strategy. In this paper, we describe an event leading to activation of our emergency WB collection strategy for the first time. We evaluate the feasibility of our civilian walking blood bank (WBB) to cover the need of a massive amount of blood in an emergency situation. The challenges are discussed in relation to the different stages of the event with the recommendations for improvement in practice. We conclude that the use of pre-screened donors as a WBB in a civilian setting is feasible. The WBB can provide platelet containing blood components for balanced blood resuscitation in a clinically relevant time frame.

Outcome after acute respiratory failure is more dependent on dysfunction in other vital organs than on the severity of the respiratory failure.

INTRODUCTION: The incidence and outcome of acute respiratory failure (ARF) depend on dysfunction in other organs. As a result, reported mortality in patients with ARF is derived from a mixed group of patients with different degrees of multiorgan failure. The main goal of the present study was to investigate patient outcome in single organ ARF. PATIENTS AND METHOD: From 1 January 2000 to 1 July 2002, all adult patients (>16 years) in the intensive care unit (ICU) at Haukeland University Hospital were scored daily using the Sequential Organ Failure Assessment (SOFA) score for organ failure. ARF was defined by the SOFA criteria: ratio of arterial oxygen tension to fractional inspired oxygen, with a value < 26.6 kPa (200 mmHg) in more than one recording during the ICU stay (SOFA score 3 or 4). Patients with ARF alone and in combination with other severe organ failure (SOFA score 3 or 4) were included. Survival was recorded on discharge from the ICU, at hospital discharge and at 90 days after ICU discharge. RESULTS: During the period of study, 832 adult patients were treated and 529 (63.0%) had ARF. The ICU, hospital and 3-month mortality rates were lowest in single organ ARF (3.2, 14.7 and 21.8%, respectively), with increasing mortality with each additional organ failure. When ARF occurred with four or five additional organ failures, the 3-month mortality rate was 75%. No significant differences in mortality were found between early and late ARF. CONCLUSION: The prognosis for ICU patients with single organ ARF is good, both in the short and long terms. The high overall mortality rate observed is caused by dysfunction in other organs.

Effect of a scoring system and protocol for sedation on duration of patients' need for ventilator support in a surgical intensive care unit.

PROBLEM: Need for improved sedation strategy for adults receiving ventilator support. DESIGN: Observational study of effect of introduction of guidelines to improve the doctors' and nurses' performance. The project was a prospective improvement and was part of a national quality improvement collaborative. BACKGROUND AND SETTING: A general mixed surgical intensive care unit in a university hospital; all doctors and nurses in the unit; all adult patients (>18 years) treated by intermittent positive pressure ventilation for more than 24 hours. KEY MEASURES FOR IMPROVEMENT: Reduction in patients' mean time on a ventilator and length of stay in intensive care over a period of 11 months; anonymous reporting of critical incidents; staff perceptions of ease and of consequences of changes. STRATEGIES FOR CHANGE: Multiple measures (protocol development, educational presentations, written guidelines, posters, flyers, emails, personal discussions, and continuous feedback) were tested, rapidly assessed, and adopted if beneficial. EFFECTS OF CHANGE: Mean ventilator time decreased by 2.1 days (95% confidence interval 0.7 to 3.6 days) from 7.4 days before intervention to 5.3 days after. Mean stay decreased by 1.0 day (-0.9 to 2.9 days) from 9.3 days to 8.3 days. No accidental extubations or other incidents were identified. LESSONS LEARNT: Relatively simple changes in sedation practice had significant effects on length of ventilator support. The change process was well received by the staff and increased their interest in identifying other areas for improvement.
