Resuscitation
-
The purpose of this study is to examine the commonly held assumption that time is measured and documented accurately during resuscitation from cardiac arrest in the hospital. ⋯ Missing time data, negative calculated Utstein gold-standard process intervals, unlikely intervals of 0 min from arrest recognition to ALS interventions in units with CPR providers only, use of multiple timepieces for recording time data during the same event, and wide variation in coherence and precision of timepieces bring into question the ability to use time intervals to evaluate resuscitation practice in the hospital. Practitioners, researchers and manufacturers of resuscitation equipment must come together to create a method to collect and document accurately essential resuscitation time elements. Our ability to enhance the resuscitation process and improve patient outcomes requires that this be done.

Comparative Study
A comparison of CPR delivery with various compression-to-ventilation ratios during two-rescuer CPR.
The number of chest compressions required for optimal generation of coronary perfusion pressure remains unknown although studies examining compression-to-ventilation ratios higher than 15:2 (C:V) in animals have reported higher C:V to be superior for return of spontaneous circulation and neurologic outcome. We examined human performance of two-rescuer CPR using various C:V. ⋯ A 15:2 compression-to-ventilation ratio when performed during two-rescuer CPR results in 26s of hands off time each minute while only delivering 60 compressions. Alternative C:V ratios of 30:2, 40:2, 50:2, and 60:2 all exceed the AHA recommended 80 compressions/min while still delivering a minute volume in excess of 1l.

The first and most important treatment for the apnoeic drowning victim is the rapid alleviation of hypoxia by artificial ventilation. Recent studies have suggested that commencing resuscitative efforts with the victim still in the water may be beneficial. The aim of this pilot study was to evaluate the feasibility and efficacy of in-water unsupported rescue breathing. ⋯ This study has demonstrated the feasibility and potential efficacy of in-water unsupported rescue breathing with a victim in deep water. Furthermore, the technique was not associated with an undue prolongation of the rescue duration over a 50 m rescue. In circumstances where the trained lifeguard finds themselves with an apnoeic victim in the water, with no buoyant rescue aid available, they may consider the application of in-water, unsupported rescue breathing, especially if recovery to dry land is likely to be delayed. The effectiveness of this technique, however, remains to be proven in the open water environment.

To describe the characteristics, cause of hospitalisation and symptoms prior to death in patients dying in hospital without resuscitation being started and the extent to which these decisions were documented. ⋯ In patients who died at a Swedish University Hospital, we did not find a single case in which it was regarded as unethical not to start CPR. The patient group studied here had a poor prognosis due to a severe deterioration in their condition. To support this, we also found a high degree of documentation of DNAR. The low rate of CPR attempts after in-hospital cardiac arrest appears to be justified.

Anecdotal evidence suggests that anxiety and lack of confidence in managing acutely ill patients adversely affects performance. We evaluated the impact of attending an ALERT course on the confidence levels and attitudes of healthcare staff in relation to the recognition and management of acutely ill patients. A questionnaire, which examined knowledge, experience, confidence and teamwork, was distributed to participants prior to commencing an ALERT course. ⋯ More staff said that they would approach a registrar or a consultant for help (chi2 = 3.29, n = 131, p < 0.05; chi2 = 7.51, n = 131, p < 0.01). There was a significant improvement in attendees' confidence in working in an interdisciplinary team when caring for critically ill patients (pre 40.66; post 42.91; t = 2.32; p = 0.05). We conclude that attending an ALERT course has beneficial effects on the confidence levels and attitudes of healthcare staff in relation to the recognition and management of acutely ill patients.
