Clinical TrialPreoperative emotional states in patients with breast cancer and postoperative pain.
The present study examined the relationship between psychological variables, including anxiety, depression, and patient-controlled analgesia (PCA) use in patients who underwent radical mastectomy. ⋯ Patients with higher anxiety and depression levels had higher postoperative pain and analgesic requirements in this study.

Automated responsiveness test and bispectral index monitoring during propofol and propofol/N2O sedation.
Sedation practice, especially when non-anaesthesia personnel are involved, requires efficient anaesthetic depth monitoring. Therefore, we used prediction probability (PK) to evaluate the performance of the bispectral index (BIS) of the EEG and automated responsiveness test (ART) to predict sedation depth and loss of subject's responsiveness during propofol sedation, with and without N2O. ⋯ BIS and ART comparably predict sedation and loss of responsiveness. However, ART, because of its resistance to false-normal responses, might prove to be more useful on an individual patient basis - especially in the presence of agents that impair BIS sensitivity.

Clinical TrialLow plasma glutamine after multiple trauma: relationship with intracellular glutamine in polymorphonuclear neutrophils during prolonged ICU stay.
Aim of the study was to evaluate whether low plasma glutamine (GLN) is related to low intracellular GLN in stress-affected cells such as polymorphonuclear neutrophil (PMN). We hypothesized, that because low plasma GLN is assumed to have an impact on clinical outcome, stress-affected cells may also show low GLN contents. ⋯ No association between low plasma GLN and low intracellular GLN in PMN was found in a cohort of severely injured trauma patients with a minimum stay of 10 days at ICU.

Case ReportsCardiopulmonary resuscitation after near drowning and hypothermia: restoration of spontaneous circulation after vasopressin.
Recent animal data have challenged the common clinical practice to avoid vasopressor drugs during hypothermic cardiopulmonary resuscitation (CPR) when core temperature is below 30 degrees C. In this report, we describe the case of a 19-year-old-female patient with prolonged, hypothermic, out-of-hospital cardiopulmonary arrest after near drowning (core temperature, 27 degrees C) in whom cardiocirculatory arrest persisted despite 2 mg of intravenous epinephrine; but, immediate return of spontaneous circulation occurred after a single dose (40 IU) of intravenous vasopressin. ⋯ This case report adds to the growing evidence that vasopressors may be useful to restore spontaneous circulation in hypothermic cardiac arrest patients prior to rewarming, thus avoiding prolonged mechanical CPR efforts, or usage of extracorporeal circulation. It may also support previous experience that the combination of both epinephrine and vasopressin may be necessary to achieve the vasopressor response needed for restoration of spontaneous circulation, especially after asphyxial cardiac arrest or during prolonged CPR efforts.

Comparative StudyResource use in the ICU: short- vs. long-term patients.
Intensive care medicine uses a disproportionate share of medical resources, and little is known about the distribution of resources between different patient groups. ⋯ In this university-based, medical-surgical adult ICU, 11% of all patients stayed more than 7 days in the unit and consumed more than 50% of all resources. Thus, a highly disproportionate amount of resources were used per survivor in group L compared with those in group S.
